Stage 1 of 6 — How it works
Understanding the task and how it is marked
You are given three pictures on a topic. Your composition must be based on at least one picture — but you can use two or all three. You write a continuous narrative (story) of at least 150 words . There is no upper limit, but quality matters far more than length.
Content & Organisation
Relevance to topic, quality of ideas, narrative structure, coherence and cohesion. Is the story engaging and well-organised? Does it have a clear beginning, middle and end?
Language
Accuracy of grammar, spelling and punctuation. Range and appropriateness of vocabulary. Sentence variety. Is the language precise, expressive and error-free?
What distinguishes a distinction-level composition: a strong hook, a clearly developed conflict or problem, emotional depth, varied sentence structures, precise vocabulary (not just "nice" or "said"), and a meaningful ending. Simply retelling the picture scores low.
Stage 2 of 6 — Planning
Plan before you write — 5 minutes well spent
Many students jump straight into writing and run out of ideas midway, or write a flat story with no tension. Spending 5 minutes planning saves time and dramatically improves the composition.
The 5-question planning method
1
Who is in the story? Name your character(s) and give them one clear personality trait.
2
Where and when does the story happen? Pick a specific setting.
3
What is the problem or conflict? This is the engine of the story. Without a problem, there is no story.
4
What happens next? The character tries to solve the problem — with a complication or turning point.
5
How does it end? Resolution + reflection. What did the character learn or feel?
Aim for 4 to 5 paragraphs . A 250–350 word composition with good language is far better than a 500-word one that rambles. Do not write more than you can proofread and edit in the time available.
Stage 3 of 6 — Structure
The 5-paragraph narrative structure
Para 1
Open with impact. Start in the middle of action, with dialogue, a surprising detail, or a vivid description — NOT "One day..." or "It was a sunny morning." Introduce setting and character quickly.
Para 2
Set the scene more fully. Introduce the situation leading to the problem. Show the character's feelings and motivations through actions and thoughts, not just "he was nervous."
Para 3
The heart of the story. The problem or conflict arrives. This is where the tension peaks. Use short sentences for urgency, dialogue for immediacy, and precise verbs to show action.
Para 4
The character resolves the problem — or fails to, but learns something. Show the change. Avoid deus ex machina endings ("then a kind stranger appeared"). The resolution should feel earned.
Para 5
End with meaning. The character reflects on what happened. A memorable final line — perhaps linking back to the opening image — makes the composition feel complete and crafted.
Avoid these structural mistakes: starting with waking up, ending with "it was all a dream," having too many characters, changing setting too many times, or spending 3 paragraphs on setup with no conflict.
Stage 4 of 6 — Language
Upgrading your language — the most learnable skill
Replacing weak, overused words
Weak "He was very scared and ran away quickly."
Strong "Terror gripped him. He bolted down the corridor, his footsteps echoing in the empty hallway."
Weak "She said, 'We have to go now.'"
Strong "She grabbed his arm. 'We have to go — now,' she whispered, her voice barely steady."
Replacing "said" — use precise speech verbs
whispered · insisted · pleaded · announced · stammered · exclaimed · murmured · snapped · urged · confessed · admitted · questioned
Show, don't tell — show emotions through actions
Tell "She was very happy."
Show "A wide smile spread across her face. She let out a laugh she had been holding in for days."
Tell "He felt guilty."
Show "He could not meet her eyes. His fingers tightened around the edge of the table."
Vary sentence length deliberately. Short sentences create tension: He froze. The lights went out. Longer sentences build atmosphere and description. Mixing both shows control of language.
Stage 5 of 6 — Sample composition
Annotated sample: "A Helping Hand"
Topic: Helping others. Picture stimulus: a child fallen off a bicycle, another child kneeling beside them.
"Don't move!" The words left Kai's mouth before he even realised he had stopped pedalling. Across the park path, a girl lay on the ground, her bicycle wheels still spinning uselessly in the air.
Hook: opens mid-action with dialogue. Establishes character and setting in two sentences.
He had been in a hurry — his mother was waiting at the café entrance, and he was already ten minutes late. But something made him dismount, lean his bicycle against the nearest tree, and jog over. The girl, who looked about eight, was clutching her knee, tears streaking silently down her dusty face.
Build-up: shows the character's conflict between self-interest and helping. Uses "tears streaking silently" — precise, visual language.
"It hurts," she managed. Her voice was barely a whisper. Kai crouched beside her and examined the wound — a raw, red scrape that had begun to bleed. He had no plasters, no cloth, nothing useful. Around them, cyclists and joggers streamed past without a second glance.
Conflict: the problem deepens. The detail of passers-by ignoring them adds emotional weight and a subtle commentary.
He pulled off his jacket, tore a strip from the lining — something his mother would later lecture him about — and pressed it gently against the wound. Then he helped the girl to her feet and walked her to a nearby bench, where her father was already rushing over, pale-faced and relieved.
Resolution: practical, believable, character-driven. The parenthetical "(something his mother would later lecture him about)" adds a touch of humour and reveals character.
Later, cycling home with a jacket that had a slightly shorter lining, Kai found he did not mind being late at all. Some things, he thought, were more important than being on time.
Reflection: short, simple, meaningful. Links back to the opening urgency. The final line delivers the story's message without stating it crudely.
Word count: ~270 words. This demonstrates that a focused, well-crafted composition does not need to be long to score well.
Stage 6 of 6 — Common mistakes
10 mistakes that cost marks — and how to fix them
1
Opening with "One day" or "It was a __ morning." → Start with action, dialogue, or a striking image instead.
2
Ending with "It was all a dream." → This invalidates the entire story. Examiners penalise this heavily.
3
Using "said" for every piece of dialogue. → Use precise speech verbs: whispered, insisted, stammered, urged.
4
No conflict or problem. → Without tension, there is no story. Every narrative needs a challenge to overcome.
5
Too many characters. → Stick to 2–3. Too many names confuse the reader and dilute focus.
6
Writing in point form or notes. → Must be continuous prose — full sentences, proper paragraphs.
7
Retelling the picture literally. → The picture is a stimulus, not a script. Build a story around it, don't just describe it.
8
Telling emotions instead of showing them. → "He was sad" → "He stared at the floor and said nothing."
9
All sentences the same length. → Vary length deliberately — short for tension, longer for description.
10
Not leaving time to proofread. → Reserve 3–5 minutes to check grammar, spelling and punctuation. One sweep can recover several marks.

Stage 1 of 5 — Overview
What situational writing tests
You are given a situation — a context, a purpose, an audience, and a set of content points you must cover. You write a short functional piece in response. The text type is usually specified: formal letter, informal email, report, speech, or notice.
Formal letter
To a principal, manager, organisation or public official. Full block format with sender's address, date, salutation, body, sign-off.
Informal email / letter
To a friend, pen pal or relative. Friendly tone, contractions allowed, no full address needed — but still organised.
Report
To a teacher, committee or organisation. Headed sections (Introduction, Findings, Recommendations). Factual, objective tone.
Speech / Notice
Speech: to an audience, direct address. Notice: brief, clear, to the point. Both need a heading and clear structure.
The two things that lose marks most: (1) missing one or more of the required content points — each missing point costs marks regardless of how well the rest is written; (2) using the wrong register — writing informally to a principal, or formally to a friend.
Stage 2 of 5 — Register & Tone
Formal vs informal — getting the register right
Register is how you adjust your language for your audience. In PSLE, the audience is always specified. Read the situation carefully and identify: who are you writing to?
Formal register — for officials & strangers
Full forms: "I am writing to..." not "I'm"
Informal register — for friends & family
Contractions allowed: "I'm," "it's," "we'll"
Same content point — two registers
Wrong register (informal to principal) "Hey, the canteen food is really bad and we all hate it. Can you fix it?"
Correct (formal to principal) "I would like to bring to your attention that many students find the current canteen menu limited in variety. We respectfully request that healthier options be considered."
Stage 3 of 5 — Formal Letter Format
The formal letter — full annotated template
This is the most commonly tested text type. Every element must be in the right place and correctly formatted.
Sender's address 12 Orchid Drive
Your address — top right or top left. No name here.
Date 15 March 2025
Write date in full. Not "15/3/25."
Recipient The Principal
Title and address of the person you are writing to.
Salutation Dear Mr Tan,
"Dear Sir/Madam," if the name is not given. Always a comma after the name.
Subject line Feedback on the School Canteen
Bold or underlined. Tells the reader the purpose immediately. Not always required but recommended.
Opening I am writing on behalf of the students of Class 6A to share our feedback regarding the school canteen.
State your purpose in the first sentence. "I am writing to..." is the standard opener.
Body Firstly, we would like to suggest that the canteen offer a wider variety of healthy food options... [cover each content point in a separate paragraph or clearly separated point]
One paragraph per main point. Use signposting words: Firstly, In addition, Furthermore, Finally.
Closing I hope you will consider our suggestions. Thank you for your time and attention.
Polite, professional close. Do not end abruptly.
Sign-off Yours sincerely,
"Yours sincerely" when name is known. "Yours faithfully" when "Dear Sir/Madam." Then your name, then your role if given.
Stage 4 of 5 — Content Points
Covering all content points — the most common mark loss
The situation will specify 3 to 5 content points you must address. These are not optional. Missing even one costs marks, no matter how beautifully written the rest is. Before you write, number the content points and tick them off as you cover each one.
Sample situation and content points
Situation: Your school is organising a recycling drive. Write a letter to parents informing them about the event. In your letter, include:
✓
Purpose: "We are organising this drive to promote environmental awareness and reduce waste in our school community."
✓
Items: "Acceptable items include old newspapers, glass bottles, plastic containers and electronic waste."
✓
Date/location: "The event will be held on 22 March 2025 at the school hall from 8 a.m. to 12 p.m."
✓
How to participate: "Parents are welcome to drop off items on the day or send them with their children by 20 March."
✓
Request for support: "We sincerely hope that you will lend your support to this meaningful initiative."
Expand each content point with at least one supporting detail or reason — do not just list them as bullet points. Write in full, connected sentences even when covering straightforward information.
Stage 5 of 5 — Common mistakes & checklist
Before you submit — the situational writing checklist
10 common mistakes and how to avoid them
1
Wrong sign-off pairing. "Yours faithfully" goes with "Dear Sir/Madam." "Yours sincerely" goes with a named person. Mixing them up costs a mark.
2
Missing the sender's address. In a formal letter, your address must appear before the date. Many students skip it.
3
Skipping a content point. Each missed point loses marks. Number and check off every point before finishing.
4
Wrong register. "I'm writing because..." in a formal letter to a principal. Use full forms and formal vocabulary.
5
No opening statement of purpose. Start with why you are writing. "I am writing to..." sets context immediately.
6
No closing paragraph. Always end with a polite closing: "I look forward to your response" or "Thank you for your kind attention."
7
Bullet points instead of prose. Content points must be written as paragraphs, not a list, unless specifically instructed otherwise.
8
Wrong text type format. If asked for a report, use section headings. If asked for a speech, address the audience directly ("Good morning, everyone...").
9
No signposting words. Connect content points with transitions: Firstly, In addition, Furthermore, Finally, I would also like to highlight...
10
Using "I" throughout a report. Reports use objective language: "It was observed that..." / "The survey revealed..." not "I found that..."

Three question types — what each one asks
Literal
The answer is directly stated in the passage. Find it, rephrase it in your own words. Do not copy word-for-word.
Inferential
The answer is not stated — you must "read between the lines" using evidence from the passage to support your reasoning.
Evaluative
Your opinion is required, but it must be justified with evidence from the passage. Both opinion AND support must be present.
The passage — read carefully before attempting the questions
[1] The morning of the regional science fair began with a sky the colour of old pewter, heavy with the promise of rain. Maya had been awake since four o'clock, rehearsing her presentation in the cramped bathroom mirror while her parents slept. She had worked on her project — a study of air quality in different parts of the city — for six months. Today, it would either be worth it or it would not.
[2] The community centre hall buzzed with the energy of forty-seven competitors. Maya found her assigned table and began arranging her display boards, her hands steadier than she had expected. The girl at the next table — Priya, her badge said — had a project about underwater robotics that gleamed under the fluorescent lights. Maya stole a glance and immediately regretted it. Priya's project looked like something from a university laboratory.
[3] "First time?" Priya asked, noticing Maya's expression. "Me too," she added before Maya could answer. "I've been awake since three." Maya exhaled slowly. Something about the admission made the air around both of them feel slightly lighter.
[4] The judging began at ten. Maya watched five competitors present before it was her turn. Two stumbled over their words; one had clearly memorised her script so thoroughly that she sounded like a recording rather than a person. Maya made a quiet decision: she would speak as if she were explaining her project to a curious friend, not performing for a panel of strangers.
[5] When her name was called, Maya walked to the front of her display and looked directly at the lead judge — a tall woman with reading glasses perched on her head. "I started this project," Maya began, "because I noticed something strange on my way to school." For the next eight minutes, she forgot she was being judged at all.
[6] The results were announced at noon. Priya's underwater robotics project won first place. Maya's project was awarded second. She clapped genuinely — she had watched Priya's presentation and found it extraordinary — and when Priya caught her eye across the hall, both of them grinned, the way people do when they have shared something difficult and come out the other side of it.
Literal questions — the answer is in the passage
Question 1 — Literal (1 mark)
Find and rephrase
What was Maya's science fair project about? (paragraph 1)
Show model answer
Maya's project investigated the quality of air in different parts of the city.
Why this earns full marks: The answer rephrases "a study of air quality in different parts of the city" in the student's own words. Copying the passage word-for-word ("a study of air quality in different parts of the city") risks scoring zero — examiners look for evidence that you have understood the text, not just copied it.
Question 2 — Literal (2 marks)
Find two points
Give two things Maya observed about the other competitors before her turn to present. (paragraph 4)
Show model answer
Firstly, two competitors struggled and hesitated during their presentations. Secondly, one competitor had rehearsed her script so well that she sounded robotic and unnatural rather than genuine.
Why this earns full marks: Two clearly distinct points, each rephrased. Notice the two points map directly to "Two stumbled over their words" and "one had clearly memorised her script... sounded like a recording." A 2-mark literal question almost always requires two separate pieces of information.
Inferential questions — read between the lines
Question 3 — Inferential (2 marks)
Evidence required
What does the phrase "immediately regretted it" (paragraph 2) suggest about how Maya felt after looking at Priya's project?
Show model answer
The phrase suggests that Maya felt intimidated and discouraged after seeing Priya's project. Looking at it made her doubt her own work, as Priya's project appeared far more advanced and professional than what Maya had produced. She wished she had not compared them, as the comparison shook her confidence.
Why this earns full marks: The answer goes beyond "she felt bad" — it explains why she regretted looking and links back to the passage detail ("looked like something from a university laboratory"). Inferential answers must name the emotion AND explain the reasoning. "She regretted it because she felt scared" earns 1/2. The explanation of what specifically caused the feeling earns the second mark.
Question 4 — Inferential (2 marks)
Character motivation
Explain why Maya decided to "speak as if she were explaining her project to a curious friend" (paragraph 4) rather than performing for the judges.
Show model answer
Maya noticed that competitors who had over-rehearsed or become nervous during their presentations came across as unconvincing — either stumbling over words or sounding mechanical. She decided that speaking naturally and conversationally, as one would to a friend, would make her presentation more genuine and engaging for the judges, and would also help her feel less anxious.
Why this earns full marks: The answer identifies the evidence (what she observed in the other competitors) and links it to her decision. Inferential questions about motivation require: (1) what the character observed/experienced, and (2) why that led to the decision. Giving only one of these earns partial marks.
Evaluative questions — your opinion, with evidence
Question 5 — Evaluative (2 marks)
Opinion + evidence
Do you think Maya showed good sportsmanship when Priya's project won first place? Support your answer with evidence from the passage.
Show model answer
Yes, I think Maya showed excellent sportsmanship. When the results were announced, she "clapped genuinely" for Priya's victory, which shows she celebrated Priya's win without bitterness or disappointment. The passage also tells us that she had genuinely found Priya's presentation "extraordinary," which suggests her applause was sincere rather than forced. Her warm grin when she caught Priya's eye across the hall further reinforces that she was truly happy for her competitor.
Why this earns full marks: The answer states a clear opinion ("Yes"), then provides two pieces of textual evidence ("clapped genuinely" and "found it extraordinary"), and explains what each piece of evidence shows. Evaluative answers without quotes or specific references from the passage earn 1/2 at most. The structure is: Opinion → Evidence 1 + explanation → Evidence 2 + explanation.
Question 6 — Evaluative (2 marks)
Theme / message
Distinction level
The writer ends the passage with the image of Maya and Priya grinning at each other "the way people do when they have shared something difficult and come out the other side of it." What message do you think the writer wants to convey through this ending?
Show model answer
I think the writer wants to convey that shared challenges can create genuine connections between people, and that the experience of overcoming difficulty together — even as competitors — can be more meaningful than the outcome. Both Maya and Priya were nervous strangers at the start of the day (Priya confessed she had been awake since three), but by the end, their shared experience had turned them into something closer to friends. The ending suggests that competing with integrity and mutual respect can be as rewarding as winning itself.
Why this earns full marks: This is a theme/message question — the most demanding evaluative type. It requires identifying a universal idea the writer is exploring (shared struggle builds connection; integrity matters more than outcome) and supporting it with evidence from across the passage, not just the final line. Answers that simply say "the writer wants to show that they became friends" earn 1/2. Connecting the theme to broader ideas about competition, resilience or human connection earns the second mark.

Grammar rules most frequently tested in PSLE
Tenses
Simple past, simple present, present perfect (have/has + past participle), past continuous, future tense
Subject-verb agreement
Singular subject → singular verb. Plural subject → plural verb. Watch: "each," "every," "neither," "either"
Articles
a (before consonant sounds), an (before vowel sounds), the (specific/known). No article for general plurals
Prepositions
in/on/at for time and place. "interested in," "afraid of," "responsible for," "consist of" — fixed collocations
Modals
can/could, will/would, may/might, must/have to, should — each has a specific meaning about possibility, permission or obligation
Word form
Noun/verb/adjective/adverb — using the correct form: "decide" (v) / "decision" (n) / "decisive" (adj) / "decisively" (adv)
Part A — Grammar MCQ (Booklet A style · 1 mark each)
Question 1 Tense
By the time the rescue team ________ the collapsed building, three survivors had already been found.
A had reached
B reached
C reaches
D will reach
Correct answer: B — reached. "By the time + simple past " is the standard construction. "Had already been found" (past perfect) describes what happened first ; the team reaching the building happened after , so simple past is correct. Past perfect (A) would create two past-perfect clauses with no sequence distinction. Present (C) and future (D) tenses don't fit a past narrative.
Question 2 Subject-verb agreement
Neither the students nor the teacher ________ aware of the change to the timetable.
Correct answer: B — was. With "neither...nor", the verb agrees with the subject closest to it (nearest-noun rule). Here "the teacher" is singular → "was". If the order were reversed ("neither the teacher nor the students"), the verb would agree with "the students" → "were". "Is" (C) is present tense and doesn't fit the past context.
Question 3 Articles
She was ________ only child who volunteered to lead ________ expedition through ________ Amazon.
A an / an / the
B the / a / a
C the / the / the
D an / the / the
Correct answer: C — the / the / the. All three blanks need "the": (1) "the only child" — superlative/unique reference demands the definite article; (2) "the expedition" — a specific expedition being discussed; (3) "the Amazon" — rivers and major geographical features always take "the". "An" (A, D) is wrong here because we need a definite article, not an indefinite one. "A expedition" / "a Amazon" (B) are both ungrammatical.
Question 4 Preposition / collocation
The committee is responsible ________ ensuring that all participants are treated fairly, regardless ________ their background.
A for / about
B of / of
C for / of
D with / from
Correct answer: C — for / of. Both are fixed collocations that must be memorised: "responsible for" and "regardless of" . "Responsible of" (B) and "regardless about" (A) are ungrammatical. "With / from" (D) fits neither slot. Preposition collocations are heavily tested in PSLE — keep a list of common ones: "interested in", "afraid of", "consists of", "depends on".
Question 5 Modal verbs
You ________ return the library books by Friday, or you will be charged a fine.
Correct answer: B — must. "Must" expresses strong obligation or necessity — confirmed by the consequence of a fine. "May" (A) expresses permission or possibility. "Might" (C) expresses weak/uncertain possibility. "Could" (D) expresses ability or past possibility. None of A, C, D convey the obligation the sentence requires. Key distinction: must = obligation; may/might = possibility; could = ability.

Pattern 1 of 5
Active ↔ Passive voice
Active: Subject does the action → The chef cooked the meal. Passive: Subject receives the action → The meal was cooked by the chef. Formula: Object + was/were/is/are/has been + past participle + (by + agent)
Active: [Subject] + [verb] + [object]
Passive: [Object] + [was/were] + [past participle] + [by + subject]
Practice questions
Q1 Active → Passive
Rewrite the sentence in the passive voice.
Show model answer
The new timetable was announced by the school board yesterday.
Object ("the new timetable") becomes the subject. Past tense active "announced" → "was announced." Agent ("the school board") follows "by." Time phrase ("yesterday") stays at the end.
Q2 Passive → Active
Rewrite in the active voice.
Show model answer
The emergency team rescued the injured hiker within two hours.
The agent ("the emergency team") becomes the subject. "Was rescued by" reverts to simple past "rescued." "The injured hiker" becomes the object.
Common error: "The emergency team was rescued the injured hiker" — never use "was/were" in an active sentence. Remove it entirely when converting to active.
Q3 Using the given word
Combine using the given word. Do not change the given word.been
Show model answer
My bicycle has been stolen.
Present perfect passive: has + been + past participle. The agent is unknown so "by someone" is omitted — this is natural in English when the doer is unspecified.
Pattern 2 of 5
Direct ↔ Reported (indirect) speech
Convert between what someone actually said ("direct") and a description of what they said ("reported").Key changes when converting to reported speech:
Direct: She said, "I am tired."
Reported: She said that she was tired.
Direct: He asked, "Where is the station?"
Reported: He asked where the station was.
Practice questions
Q1 Direct → Reported (statement)
Rewrite in reported speech.
Show model answer
The manager told the team that they would submit the report by Friday.
"Will" → "would." "We" → "they." "Told" is already past tense — no change needed. "By Friday" remains (it refers to a fixed deadline, not a relative time word).
Q2 Direct → Reported (question)
Rewrite in reported speech.
Show model answer
Auntie Mei asked her nephew if he had ever visited the science museum.
Yes/no questions use "if" or "whether." Present perfect "have you visited" → past perfect "had ever visited." "You" → "he." No question mark in reported speech — it becomes a statement structure.
Common error: "Auntie Mei asked her nephew had he ever visited..." — reported questions use statement word order (subject before verb), not question word order.
Q3 Using the given word
Rewrite using the given word.not
Show model answer
The guide warned the visitors not to touch the exhibits.
Reported commands use "told/warned/advised/asked + object + (not) + to-infinitive." "Don't touch" → "not to touch." The structure is: warned + them + not to + base verb.
Pattern 3 of 5
Combining sentences — conjunctions & connectors
Join two sentences using the given word. The meaning must stay exactly the same — changing the meaning scores zero even if the grammar is correct.
despite / although → contrast (something unexpected)
so...that → result of a degree/intensity
unless → negative condition (= "if not")
so that / in order to → purpose
neither...nor → two negatives combined
not only...but also → adding emphasis
Practice questions
Q1 despite
She was exhausted. She continued to work late into the night.despite
Show model answer
Despite being exhausted, she continued to work late into the night.
"Despite" is followed by a noun or gerund (-ing form), NOT a clause. "Despite she was exhausted" is wrong. The correct structure: despite + noun/gerund + comma + main clause.
Despite vs although: "Despite" + noun/gerund. "Although" + full clause (subject + verb). Never write "despite that she was exhausted."
Q2 so...that
The queue was very long. We decided not to wait.so
Show model answer
The queue was so long that we decided not to wait.
"So + adjective/adverb + that + result clause." The adjective "long" goes between "so" and "that." The result clause must follow "that." Do not use a comma between "so...that."
Q3 unless
If you do not practise daily, your piano skills will not improve.unless
Show model answer
Your piano skills will not improve unless you practise daily.
"Unless" = "if not." Remove the negative from the condition: "do not practise" → "practise." "Unless" already contains the negative, so never write "unless you do not practise" — this creates a double negative and reverses the meaning.
Q4 not only...but also
The new community centre has a swimming pool. It also has a library and a gym.not only
Show model answer
The new community centre not only has a swimming pool but also a library and a gym.
"Not only...but also" pairs two related pieces of information. When the subject is the same in both clauses, the subject is not repeated: "...but also [has] a library..." — "has" is implied and can be omitted.
Pattern 4 of 5
Conditional sentences (if-clauses)
Real condition (likely): If + present simple → will + base verbIf it rains, we will cancel the picnic. Hypothetical (unlikely): If + past simple → would + base verbIf I were a bird, I would fly to Paris. "were" (not "was") after "if" for hypothetical conditions — even with "I."
Practice questions
Q1 Real condition → If-sentence
You study hard. You will pass the examination.If
Show model answer
If you study hard, you will pass the examination.
Real condition: If + present simple ("study") → will + base verb ("will pass"). Comma after the if-clause when it comes first. No comma needed if the main clause comes first: "You will pass the examination if you study hard."
Q2 Rewrite as conditional
He doesn't exercise regularly, so he doesn't feel energetic.If
Show model answer
If he exercised regularly, he would feel energetic.
Hypothetical condition: the original implies he currently does NOT exercise. To express what would happen if he did, use: If + past simple ("exercised") → would + base verb ("would feel"). This is Type 2 conditional — for unlikely or unreal present situations.
Common error: "If he exercises regularly, he will feel energetic" — this is grammatically correct but changes the meaning. The original states he does NOT exercise, so the hypothetical form (Type 2) is required to preserve the original meaning.

Q1 although
The film received mostly negative reviews. Thousands of people went to watch it.Although
Show model answer
Although the film received mostly negative reviews, thousands of people went to watch it.
"Although" + full clause (subject + verb). Comma after the "although" clause when it starts the sentence. Unlike "despite," "although" takes a full clause — do not write "Although receiving negative reviews..."
Q2 asked
"Can you show me the way to the post office?" the tourist said to the shopkeeper.asked
Show model answer
The tourist asked the shopkeeper to show him/her the way to the post office.
This is a polite request ("Can you...?"), so it is reported as: asked + object + to-infinitive. "Can you show me" → "to show him/her." Note: "me" changes to "him/her" depending on the tourist's gender (use either — the examiner accepts both).
Q3 whose
The scientist won the Nobel Prize. Her research changed our understanding of climate change.whose
Show model answer
The scientist whose research changed our understanding of climate change won the Nobel Prize.
"Whose" is a relative pronoun showing possession — it replaces "her/his" to connect the two sentences. The relative clause ("whose research changed...") is embedded into the main sentence. The main verb "won" stays at the end of the complete sentence.
Q4 had
We did not review the safety procedures. The accident happened.had
Show model answer
Had we reviewed the safety procedures, the accident would not have happened.
This is a Type 3 conditional (past hypothetical — the event did NOT happen). The inverted form "Had we reviewed..." replaces "If we had reviewed..." — this is a formal/literary structure. Full form also accepted: "If we had reviewed the safety procedures, the accident would not have happened."
The "had" inversion is rare but tested: When "had" begins the sentence, the "if" is dropped and the subject and "had" are swapped: "If we had..." → "Had we..." The meaning is unchanged.

Q1 Vocabulary Cloze
The young scientist was so in her research that she often forgot to have lunch, spending hours in the laboratory without a break.
(1) keen
(2) absorbed
(3) happy
(4) excited
Correct answer: (2) absorbed. "So absorbed in her research that she forgot to have lunch" captures being completely engrossed or occupied — the mind so focused it forgets basic needs. "Keen" means enthusiastic but does not explain forgetting lunch. "Happy" and "excited" describe emotional states, not the depth of mental focus that causes someone to lose track of time.
Q2 Vocabulary Cloze
The documentary the devastating impact of plastic waste on ocean wildlife, showing footage that deeply unsettled many viewers.
(1) mentioned
(2) depicted
(3) implied
(4) suggested
Correct answer: (2) depicted. "Depicted" means showed or represented something visually and directly — the right word for a documentary using actual footage. "Mentioned" is too weak (only a brief reference). "Implied" means hinted at indirectly, the opposite of showing footage. "Suggested" also conveys something indirect — none of these match the directness of actual film footage. "Depicted" is the precise choice.
Q3 Vocabulary Cloze
The team showed determination, refusing to concede defeat even after losing the first two sets of the match.
(1) mild
(2) genuine
(3) fierce
(4) quiet
Correct answer: (3) fierce. "Fierce determination" is a natural collocation meaning intense, passionate resolve — exactly right for a team that refuses to give up despite being two sets down. "Mild" is far too weak. "Genuine" means real or sincere, but does not convey the intensity described. "Quiet" means subdued, which does not fit the fighting spirit shown by refusing to concede.
Q4 Vocabulary Cloze
Hundreds of volunteers were deployed to the damage caused by the storm before the next wave of rain arrived.
(1) repair
(2) assess
(3) control
(4) reduce
Correct answer: (2) assess. "Assess the damage" is the correct collocation — it means to evaluate or measure the extent of the damage, which is the logical first step before any repairs. "Repair" means to fix, but you cannot repair damage before you know how bad it is, and "repair" would take far longer than the time available. "Control" and "reduce" do not collocate naturally with "damage" in this context.
Q5 Vocabulary Cloze
Mrs Lee her students for their exceptional performance at the competition, noting that their dedication had been an inspiration to the whole school.
(1) congratulated
(2) praised
(3) commended
(4) thanked
Correct answer: (3) commended. "Commended" means formally praised and recognised someone's merit — the most precise word for a teacher officially recognising exceptional performance and citing it as an example to others. "Congratulated" expresses good wishes upon an achievement but does not carry the sense of formal public recognition. "Praised" is close but less formal. "Thanked" implies gratitude for a favour done, which is not what the sentence describes.

When Ethan first joined the school robotics club, he had no experience with coding or engineering. Yet his enthusiasm (6) was undeniable — he arrived early to every session and stayed late, asking the senior members countless questions.

When the club clinched (10) the championship trophy, his teammates cheered, knowing that Ethan's persistence had made all the difference.
Adapted from a fictional account
Q6 Vocabulary — enthusiasm
(1) determination
(2) eagerness
(3) talent
(4) confidence
Correct answer: (2) eagerness. "Enthusiasm" means strong eagerness, interest and excitement about something. "Eagerness" is the closest synonym — both describe a keenness and readiness to engage. "Determination" means resolve (a different quality). "Talent" means natural ability (Ethan explicitly has no experience, so talent is wrong). "Confidence" means self-assurance, which is not what enthusiasm describes.
Q7 Vocabulary — relentless
(1) growing
(2) obvious
(3) unceasing
(4) natural
Correct answer: (3) unceasing. "Relentless" means never stopping, never giving up despite difficulty — unceasing. Context: his curiosity drove him to read widely and experiment even when attempts failed, showing it never let up. "Growing" means increasing over time (a different idea). "Obvious" means easy to see. "Natural" means innate — the passage shows his curiosity was persistent, not that it was inborn.
Q8 Vocabulary — innovative
(1) practical
(2) ambitious
(3) creative
(4) complex
Correct answer: (3) creative. "Innovative" means introducing new and original ideas. "Creative" is the closest synonym — both involve imaginative, original thinking. "Practical" means useful and realistic (does not capture originality). "Ambitious" means having great aspirations. "Complex" means complicated — the passage does not describe the ideas as complicated, only as new and impressive.
Q9 Vocabulary — devised
(1) found
(2) suggested
(3) worked out
(4) tested
Correct answer: (3) worked out. "Devised" means carefully thought through and came up with — it implies a process of reasoning and invention. "Worked out" captures this best: arriving at a solution through thought and effort. "Found" suggests stumbling upon something by chance. "Suggested" is too weak (only proposing, not fully solving). "Tested" means tried out — the sentence says he came up with the solution, not that he tested it.
Q10 Vocabulary — clinched
(1) collected
(2) earned
(3) won
(4) achieved
Correct answer: (3) won. "Clinched" means secured a win decisively, especially in a competition. "Won" is the closest and most direct synonym. "Collected" describes physically picking something up, not winning it. "Earned" implies deserving through effort (close, but does not specifically mean winning a contest). "Achieved" is similarly broad — you achieve goals, not championships specifically. "Won" is the clearest match in a competition context.

Singapore Water Authority · Public Health Campaign
Every Drop Counts.
Did you know? The average Singapore household wastes up to 30 litres of water daily through leaking taps and long showers — enough to fill 150 drinking glasses.
Fix leaking taps immediately — a dripping tap wastes 20,000 litres a year
Shorten your shower by 2 minutes and save up to 15 litres per wash
Use a pail instead of running water when washing your car
Collect cool-down water from the tap for watering plants
Take the 30-Day Water Challenge → SaveWater.sg
Brought to you by the Singapore Water Authority in partnership with schools and community centres island-wide.
Q1 Literal
According to the advertisement, how much water does the average Singapore household waste daily?
A 20 litres
B 30 litres
C 150 litres
D 20,000 litres
Correct: B — 30 litres. The "Did you know?" panel states "up to 30 litres of water daily." 150 is the number of drinking glasses (not litres), 20,000 litres is the yearly waste from a leaking tap (not a daily figure), and 20 litres is a distracter — it does not correspond to any figure stated in the advertisement.
Q2 Inferential
What is the most likely reason the advertisement compares 30 litres of water to "150 drinking glasses"?
A To explain how drinking glasses should be used to save water.
B To show that Singapore households use too many drinking glasses.
C To make the amount of wasted water feel more concrete and relatable to readers.
D To compare the cost of water in Singapore to the cost of buying glasses.
Correct: C. Converting an abstract volume (30 litres) into a familiar, visual quantity (150 glasses) makes the scale of waste more tangible and emotionally impactful for the reader. This is a common persuasive technique in public health advertisements.
Q3 Inferential
The advertisement uses the phrase "Every drop saved today is a drop secured for tomorrow." What does this suggest about Singapore's water situation?
A Singapore currently has a shortage of drinking water.
B Water conservation now will help ensure adequate water supply in the future.
C Drinking water in Singapore will become too expensive in the future.
D Singapore imports all of its water and must save more to reduce costs.
Correct: B. The phrase implies a forward-looking concern — present conservation habits protect future supply. A and C go further than what the text states (no current shortage or price issue is mentioned). D introduces a detail (imports) not supported by the advertisement.
Q4 Evaluative · visual element
The advertisement ends with a call to action: "Take the 30-Day Water Challenge → SaveWater.sg". What is the purpose of including a website address?
A To prove that the advertisement was created by a real organisation.
B To show that the Singapore Water Authority has a modern digital presence.
C To provide readers with a next step so they can take action beyond reading the advertisement.
D To allow readers to report households that are wasting water.
Correct: C. A website address in an advertisement serves as a call-to-action bridge — it moves the reader from passive awareness to active participation. The purpose is engagement and behaviour change, which is the goal of public health campaigns. A is too narrow; B and D read too much into what the text supports.
Q5 Evaluative · overall purpose
What is the main purpose of this advertisement?
A To inform readers about how Singapore's water supply is managed by the government.
B To entertain readers with interesting facts about water consumption in Singapore.
C To persuade readers to change their daily water habits and take part in a conservation challenge.
D To warn readers that their water bills will increase if they do not save water.
Correct: C. The advertisement gives specific tips, uses emotive language ("Every drop counts"), and ends with a direct call to action — all hallmarks of a persuasive text designed to change behaviour. "Inform" (A) is secondary to persuasion here. "Entertain" (B) is incorrect. "Warn about bills" (D) is not mentioned anywhere in the text.
Text 2 — Infographic bar chart (Q6–Q10)
Most Popular After-School Activities
Survey of 400 Primary 6 students in Singapore · 2024
*Percentages represent proportion of each gender who regularly participate. Students could select multiple activities. Survey conducted across 8 schools.
Q6 Literal · reading the chart
According to the infographic, which activity is most popular among boys?
A Sports (75%)
B Gaming (82%)
C Reading (35%)
D Arts/crafts (22%)
Correct: B — Gaming (82%). Looking at the blue bars (boys), gaming has the highest percentage at 82%. Sports is second at 75%. This is a straightforward chart-reading question — identify the correct bar colour and find the highest value.
Q7 Inferential · comparing data
Which activity shows the greatest difference in popularity between boys and girls?
A Sports (difference of 33%)
B Gaming (difference of 44%)
C Reading (difference of 33%)
D Arts/crafts (difference of 39%)
Correct: B — Gaming (44% difference). Gaming: 82% boys − 38% girls = 44%. Sports: 75% − 42% = 33%. Arts/crafts: 61% − 22% = 39%. Reading: 68% − 35% = 33%. This question requires calculating the difference for each activity — not just reading a single bar.
Q8 Inferential · reading the footnote
The footnote states that "students could select multiple activities." Why is this important for understanding the infographic correctly?
A It explains why the survey was conducted across 8 schools.
B It shows that the survey was not conducted fairly.
C It means the percentages for each gender do not need to add up to 100%.
D It suggests that most students do not have a favourite activity.
Correct: C. If students could choose more than one activity, each student's choices would contribute to multiple bars — so the percentages across activities do not sum to 100%. Without this note, a reader might think the data was wrong. Reading footnotes carefully is an important visual text skill.
Q9 Evaluative · drawing conclusions
A student concludes: "Boys are more active than girls after school." Does the infographic fully support this conclusion? Explain your answer.
A Yes — boys have higher percentages in physical activities like sports and gaming.
B Yes — boys clearly prefer outdoor activities, which makes them more active.
C Not fully — the infographic only covers four activities and does not measure physical activity levels directly.
D No — the infographic shows girls are equally active because they read more.
Correct: C. The infographic shows preferences, not activity levels, and covers only 4 activities. Gaming (a sedentary activity) is boys' most popular choice. A fair evaluation must acknowledge what the data does NOT show — and recognise that "gaming" is not "active." This is a classic evaluative question testing whether students can identify the limits of evidence.
Q10 Evaluative · purpose of infographic
Why might a school counsellor find this infographic useful?
A To identify which activities are the most expensive for students to participate in.
B To better understand students' interests when planning programmes or conversations about well-being.
C To decide which activities should be banned for students who are not performing well academically.
D To write a report proving that boys spend more time gaming than girls.
Correct: B. A school counsellor's role involves supporting student well-being and development. Understanding what students enjoy doing after school provides context for building relationships and designing relevant programmes. A, C, and D either introduce purposes not supported by the infographic or misuse the data inappropriately.

Stage 1 of 5 — Overview
Paper 4 structure and marks
Paper 4 is conducted individually with two examiners. The total time is about 15 minutes (5 minutes preparation, 10 minutes examination). It has two parts that are not linked to each other.
Part 1 — Reading Aloud (15 marks)
Read a short passage aloud to suit the purpose, audience and context. Marked on: pronunciation, clarity, fluency, expressiveness and pace. The passage is given during preparation time.
Part 2 — Stimulus-based Conversation (25 marks)
Discuss a photo with the examiners. Share opinions, personal experiences and ideas. Marked on: relevance, depth of ideas, vocabulary, grammar, fluency and ability to engage.
Part 2 is worth 25 marks — significantly more than Part 1. Many students over-prepare for reading aloud and under-prepare for the conversation. The stimulus-based conversation is the higher-stakes component and the one where the most marks are available.
Stage 2 of 5 — Reading Aloud
Reading aloud — how to score well
The passage is read to the examiners as if communicating with a real audience — not mumbled, not rushed, not robotic. The five things marked are: pronunciation , clarity , fluency , expressiveness and appropriate pace .
Sample passage (practice reading this aloud):
5 techniques for Reading Aloud
1
Pause at punctuation. Commas = short pause. Full stops = longer pause. Dashes and colons = dramatic pause. Do not run through punctuation at the same speed.
2
Stress key words. In "not to fish, not to sell, but simply to watch " — stress "watch" because it is the contrast word. Read the sentence meaning, not just the letters.
3
Vary pitch and pace. Speed up for mundane information, slow down for dramatic or emotional moments. A flat monotone pace scores low on expressiveness.
4
Lift your eyes. Periodically look up from the page and make eye contact with the examiners — this shows you are reading for communication, not just decoding words.
5
Use preparation time well. In the 5-minute preparation, quietly read the passage aloud under your breath. Mark words you find difficult to pronounce. Identify the emotional tone.
Avoid Reading too fast, swallowing word endings, running sentences together, a flat monotone throughout, or making up words when uncertain of pronunciation (pause and try your best instead).
Stage 3 of 5 — Stimulus-based Conversation
How the conversation works — and what marks it
You are shown a photo . The examiners will ask you questions about it — starting with what you see, moving to opinions, and then to your personal experiences and broader ideas. The conversation typically lasts about 3–4 minutes.
What is assessed
Relevance of responses · Range and depth of ideas · Vocabulary range and precision · Grammatical accuracy · Fluency and clarity · Ability to engage naturally with examiners
Common mistakes
One-word answers · Rehearsed-sounding recitations · Refusing to elaborate · Going off-topic · Using "very very" repeatedly instead of precise vocabulary · Treating it as a test instead of a conversation
The golden rule: Say more than you are asked. If the examiner asks "What do you see?", describe the photo fully, then offer an observation or opinion. The examiner's job is to draw you out — your job is to give them material to work with.
The 3-layer response structure
1
Observe: What do you see? Describe the photo using precise vocabulary.
2
Interpret: What do you think is happening? What might the people be feeling? Why?
3
Connect: Does this remind you of a personal experience? What do you think about the broader issue?
Stage 4 of 5 — Sample conversation
Photo prompt + annotated sample responses
Community garden
👩
👦
👴
👧
A community garden with people of different ages
Examiner: "What do you see in this photo?"
Weak answer "I see some people in a garden. They are planting vegetables."
The photo shows a community garden where people of different ages — including what appears to be an elderly man, a middle-aged woman, and two children — are working together. Some are tending to the plants while others seem to be learning from the older members of the group. The garden looks well-maintained and the atmosphere appears relaxed and cooperative.
Uses precise vocabulary ("tending to," "cooperative"). Notes age diversity. Observes the atmosphere. Adds interpretation naturally.
Examiner: "Why do you think people of different ages are gardening together here?"
Weak answer "Because it is fun to garden together."
I think community gardens are a wonderful way for different generations to connect. The younger children can learn practical skills from their elders — like how to care for plants — while the elderly residents benefit from the company and sense of purpose. It is also something that does not require much equipment, so it is very accessible. In a way, the garden becomes a reason for people who might not otherwise meet to spend time together.
Multi-layered answer. Considers both children's and elderly people's perspectives. Uses "generations," "accessible," "sense of purpose" — varied vocabulary. Ends with a broader insight about community.
Examiner: "Have you ever done something like this with people of different ages?"
Yes — at my grandmother's flat, she has a small balcony garden. I sometimes help her water the plants on weekends. She knows the name of every plant and why she grows each one — some are for cooking, some for the fragrance. I used to find it a bit boring, but I have come to appreciate those quiet Saturday mornings. I think being with older family members teaches you patience and a different way of looking at the world.
Personal and specific (not generic). Shows a change in perspective ("I used to find it boring, but..."). Connects personal experience to a broader insight. Sounds natural, not rehearsed.
Stage 5 of 5 — Preparation & common mistakes
10 habits that raise your oral score
1
Always elaborate. Never give a one-sentence answer to a conversation question. Add a reason, an example, or a personal connection every time.
2
Use precise vocabulary. Replace "nice," "good," "bad," "very" with specific words: "heartwarming," "meaningful," "challenging," "remarkably." This directly raises your language score.
3
Give your opinion. Examiners want to know what you think, not just what you observe. After describing a photo, add: "I think," "In my opinion," "It seems to me that..."
4
Acknowledge complexity. Show mature thinking: "While some people might feel... I personally think... because..." This demonstrates evaluative thinking, not just description.
5
Use examples from your life. Personal anecdotes make your responses specific and credible. Generic answers ("I think teamwork is important") score lower than specific ones ("When my class prepared for Sports Day last year...").
6
Speak at a comfortable pace. Many students rush. Slowing down improves clarity, gives you time to think, and sounds more confident. Pausing briefly to collect your thoughts is better than filler sounds ("um," "like," "you know").
7
Make eye contact with the examiners. The oral is a conversation — look at the examiner who asked the question. Staring at the table the whole time reduces your communication score.
8
Do not memorise answers. Practise thinking through a range of topics (family, community, technology, environment, school, health) so you can respond naturally to any photo. Memorised answers sound unnatural and break down under follow-up questions.
9
Ask for clarification if needed. If you don't understand a question, say "Could you please rephrase that?" — this is better than guessing and going off-topic.
10
End your answers naturally. Signal when you have finished: "...and that is why I feel community activities like this are important." Trailing off leaves the examiner unsure whether to follow up.

Question 1 — Percentage of a whole & discount
Short answer (2 marks)
Paper 2 · calculator
Discount & GST
A jacket costs $85 before discount. A shop offers a 20% discount, followed by a 9% GST on the discounted price. How much does James pay for the jacket?
$85 × 80% = $68 (after discount)
$68 × 109% = $74.12 (final price)
20% off
+9% GST
Show working & answer
Discounted = $85 × (1 − 20%) = $85 × 0.80 = $68.00
After GST = $68 × (1 + 9%) = $68 × 1.09 = $74.12
James pays $74.12
Apply operations in sequence — discount first, then GST on the new price. Do NOT apply GST to the original $85. Multiplying by 1.09 is faster than finding 9% and adding it separately.
Question 2 — Percentage increase & decrease
Structured answer (3–4 marks)

% increase / decrease
In January, a bookshop sold 450 books. In February, the number of books sold increased by 20%. In March, the number of books sold decreased by 25% compared to February.

Feb sales = 450 × 1.20 = 540 books
(a) Mar = 540 × 0.75 = 405 books
(b) Change = 405 − 450 = −45 books (a decrease)
% change = 45 ÷ 450 × 100% = 10% decrease
(a) 405 books | (b) 10% decrease from January
The trap in part (b): +20% then −25% does NOT cancel out to −5%. Always compute the actual values first, then find % change against the original January figure.
Question 3 — Find the original (whole) given the part
Long answer (4–5 marks)
Paper 2 · calculator
Find the whole · reverse %
Mrs Lee spent 35% of her monthly salary on rent and 40% of the remainder on food. She saved the rest. If she saved $1170, how much is her monthly salary?
Monthly salary (100%)
Rent (35%)
Remainder (65%)
Food (26%)
Saved $1170 (39%)
Show working & answer
Remainder After rent: 100% − 35% = 65% of salary
Food = 40% of remainder = 40% × 65% = 26% of salary
Saved = 65% − 26% = 39% of salary
39% = $1170 → 1% = $1170 ÷ 39 = $30
Salary = $30 × 100 = $3000
Monthly salary = $3000

2-part ratio · before & after
Ali and Ben had marbles in the ratio 3 : 5. After Ali gave 12 marbles to Ben, the ratio became 1 : 3. How many marbles did Ali have at first?
Before
Ali: 3 units
Ben: 5 units
After
Ali: 1u
Ben: 3 units
−12 →
Show working & answer
Let Ali have 3u marbles before. After giving 12: Ali has 3u − 12.
After ratio Ali : Ben = 1 : 3, so Ali = ¼ of total.
Total is unchanged: 3u + 5u = 8u.
After Ali = ¼ × 8u = 2u
Equation 3u − 12 = 2u → u = 12
Ali at first = 3 × 12 = 36 marbles
Ali had 36 marbles at first
Common trap
Assuming the total changes after the transfer — it doesn't. Marbles are only moved between Ali and Ben, so the total stays at 8u throughout.

3-part ratio · find each share
A sum of money is shared among Ahmad, Betty and Calvin in the ratio 4 : 7 : 9. Calvin receives $150 more than Ahmad. How much does Betty receive?
Ahmad
4 units
Betty
7 units
Calvin
9 units
difference = 5 units = $150
Show working & answer
Difference Calvin − Ahmad = 9u − 4u = 5 units
5 units = $150, so 1 unit = $150 ÷ 5 = $30
Betty = 7 units = 7 × $30 = $210
Betty receives $210
Common trap
Students sometimes subtract the ratio numbers directly: 9 − 4 = 5, but forget to use the difference to find the value of 1 unit first. Always find 1 unit before scaling up to Betty's 7 units.
Question 3 — Ratio changes after a transaction (3-part, hardest type)

3-part ratio · before & after
Distinction level
Priya, Quinn and Ravi had savings in the ratio 5 : 3 : 2. Priya gave $60 to Ravi. The ratio of their savings then became 3 : 3 : 4.
Before
Priya: 5 units
Quinn: 3u
Ravi: 2u
After
Priya: 3u
Quinn: 3u
Ravi: 4u
$60
Total unchanged
Show working & answer
Key insight Quinn's amount is unchanged (only Priya → Ravi). So Quinn's ratio part tells us the unit value.
Quinn Before: 3 units. After: 3 units. ✓ Consistent — unit size has not changed.
Priya Before: 5u. After: 3u. She lost 2 units = $60 → 1 unit = $30
(a) Priya = 5 × $30 = $150
Quinn = 3 × $30 = $90
Ravi = 2 × $30 = $60
(b) % = $60 ÷ $150 × 100% = 40%
(a) Priya $150, Quinn $90, Ravi $60 | (b) 40%
Common trap
Trying to equate ratios directly (5:3:2 vs 3:3:4) without first checking whether the unit size is the same in both ratios. Quinn's amount doesn't change — this anchors the unit value and makes the problem solvable. Always look for the unchanged quantity.

What is algebra? Using a letter for an unknown
In PSLE algebra, we use a letter (usually n , x , or a ) to represent a number we don't know yet.n . Instead of "3 times some number", we write 3n .
Writing expressions
n + 3 → 3 more than n
n − 5 → 5 less than n
3n → 3 times n
n ÷ 4 → n divided by 4
Note on notation
3n means 3 × n
(the × sign is dropped)
n/4 means n ÷ 4
(fraction bar = divide)
Write an expression: "Sam has n stickers. He gets 8 more. How many does he have now?"
Expression n + 8
Meaning original stickers + 8 new ones
Write an expression: "A box has n apples. 4 boxes altogether."
Expression 4n
Meaning 4 groups of n apples each
Stage 2 of 5
Simplifying expressions — collecting like terms
Like terms have the same letter (or are both plain numbers). You can add or subtract like terms. You cannot add unlike terms together.8n ✓ (both have n)3n + 5 ✗ (cannot combine)
Simplify: 5a + 3 + 2a − 1
Group terms = (5a + 2a) + (3 − 1)
Simplify = 7a + 2
Simplify: 10n − 4n + 6
Group terms = (10n − 4n) + 6
Simplify = 6n + 6
Brackets are NOT used at P6. The syllabus only covers simplifying without brackets — e.g. 3(n + 2) will not appear. If you see it, it is above syllabus.
Stage 3 of 5
The balance method — solving equations
An equation is like a balance scale . Both sides are equal. Whatever you do to one side, you must do to the other — keeping it balanced.
Solve: 3n + 5 = 20
3n + 5 = 20
− 5 from both sides
3n = 15
÷ 3 on both sides
n = 5
n = 5 Check: 3(5) + 5 = 15 + 5 = 20 ✓
Solve: 40 − 2n = 12
40 − 2n = 12
− 40 from both sides
−2n = −28
÷ (−2) on both sides
n = 14
n = 14 Check: 40 − 2(14) = 40 − 28 = 12 ✓
Stage 4 of 5
Substitution — evaluating expressions
Substitution means replacing the letter with a given number and computing the result. This is tested directly in Paper 1 (no calculator) and Paper 2.
If n = 4, find the value of 5n − 3
Replace n = 5 × 4 − 3
Calculate = 20 − 3 = 17
If a = 6 and b = 2, find the value of 3a + 4b
Replace = 3 × 6 + 4 × 2
Calculate = 18 + 8 = 26
Order of operations matters. Always multiply and divide before adding and subtracting — even after substituting. 5n − 3 with n = 4 is (5 × 4) − 3 = 17, NOT 5 × (4 − 3) = 5.

Triangle on straight line
In the figure, BCD is a straight line. Angle ABC = 115° and angle ACB = 38°. Find angle ACD.

Angle BAC = 180° − 115° − 38° = 27° (angle sum of triangle)
Angle ACD = 180° − 38° = 142° (angles on a straight line)
Angle ACD = 142°
Exterior angle theorem shortcut: An exterior angle of a triangle equals the sum of the two non-adjacent interior angles. Here, angle ACD is exterior to triangle ABC at vertex C. The two non-adjacent interior angles are angle ABC (115°) and angle BAC (27°). So angle ACD = 115° + 27° = 142° — same answer, one step. The straight-line method (180° − 38°) is more direct here, but both approaches are valid and give the same result.

Rhombus + triangle composite
In the figure, ABCD is a rhombus and ABE is a triangle with EB = EA. Angle DAB = 126° and angle ABE = 33°. Find angle AEB.
Show working & answer
Angle ABC = 180° − 126° = 54° (adjacent angles in rhombus sum to 180°)
EB = EA → triangle ABE is isosceles, so angle EAB = angle ABE = 33°
Angle AEB = 180° − 33° − 33° = 114°
Angle AEB = 114°
Key step: EB = EA means triangle ABE is isosceles with the two equal angles at B and A. So angle EAB = angle ABE = 33°. The rhombus angle was a distractor here — angle DAB is not needed to find angle AEB once you identify the isosceles triangle.

Show working & answer
Angle ABC = 180° − 58° = 122° (co-interior angles, AD ∥ BC, sum to 180°)
Angle ABE = angle ABC − angle CBE = 122° − 42° = 80°
Angle BAE = angle DAB = 58° (E lies on AD, so angle BAE is the same as angle DAB)
Angle AEB = 180° − 80° − 58° = 42°
Angle AEB = 42°
The key property for trapeziums: Co-interior angles (also called allied angles) between parallel lines sum to 180°. Here AD ∥ BC, so angle DAB + angle ABC = 180°. This is the one trapezium property that must be memorised — it is the only way to link the two parallel sides.

Classic wrong answer: (78 + 83) ÷ 2 = 80.5. This only works if both groups are the same size. Since Class B is larger (30 vs 20), it pulls the combined average closer to 83. The correct answer of 81 is indeed closer to 83 than to 78 — always sense-check this way.

Pie Charts · Stage 1 of 5
The key idea — 360° = the whole = 100%
A pie chart is a circle split into sectors. The full circle = 360° , always representing the whole (100%) .
Angle → Percentage
% = angle ÷ 360 × 100%
e.g. 90° → 90 ÷ 360 × 100 =
25%
Percentage → Angle
Angle = % ÷ 100 × 360°
e.g. 25% → 25 ÷ 100 × 360 =
90°
Pie Charts · Stage 2 of 5
Reading a pie chart — angle to value
When you know a sector's angle and the total, find the value in two steps:
60°
90°
120°
90°
Swim
Cycle
Run
Other
The pie chart shows how 360 students travel to school. How many students cycle to school?
Fraction for Cycle = 90° ÷ 360° = ¼
No. who cycle = ¼ × 360 = 90 students
No. who run = 120/360 × 360 = ⅓ × 360 = 120 students
Always simplify the fraction first (90/360 = ¼) before multiplying. It is easier to compute ¼ × 360 than 90/360 × 360 directly.
Pie Charts · Stage 3 of 5
Using percentage labels
Some pie charts show percentages instead of angles. The method is the same — percentage acts like the fraction numerator over 100.
20%
35%
30%
15%
Books
Food
Transport
Others
A student spends $800 a month. The pie chart shows how the money is spent. (a) How much is spent on food? (b) What angle represents Transport?
(a) Food ($) = 35% × $800 = 35/100 × 800 = $280
(b) Transport (°) = 30/100 × 360° = 108°
(a) $280 | (b) 108°
Pie Charts · Stage 4 of 5
Finding the total from a sector's value
Sometimes you are given a sector's value and its percentage (or angle), and must find the total . This is the reverse operation.
15% of students in a school chose Science as their favourite subject. If 60 students chose Science, how many students are there altogether?
15% → 60 1% = 60 ÷ 15 = 4
Total (100%) = 4 × 100 = 400 students
A sector with angle 72° represents 48 people. How many people does the whole pie chart represent?
Fraction = 72 ÷ 360 = ⅕
⅕ of total = 48 Total = 48 × 5 = 240 people
Convert angle → fraction first (72° ÷ 360° = ⅕), then apply "find the whole." This avoids converting to % and back again.
Pie Charts · Stage 5 of 5
Comparing two pie charts — True / False / Not Possible to Tell
A common PSLE question shows two pie charts side by side (e.g. two shops). Because pie charts only show proportions, you cannot compare actual quantities between charts unless the totals are given or can be deduced.
Shop A
Lemon 25%
Mango 75%
Shop B
Lemon 17%
Mango 83%
Statement: "Shop A sold more Lemon ice-cream than Shop B."
Key rule Pie charts show proportions , not actual quantities.
Shop A Lemon = 25% of Shop A's total
Shop B Lemon = 17% of Shop B's total
Verdict If Shop B sold far more ice-cream overall, Shop B's 17% could be more than Shop A's 25%. We don't know the totals. → Not Possible to Tell
⚠ Only compare quantities between two charts if the total for each chart is given (or derivable from given data).

Reading a bar graph accurately
Always read the y-axis scale carefully. Check:

20
40
60

Mon
Tue
Wed
Thu
Steps (×100)
The bar graph shows steps taken on 4 days. Each unit = 100 steps. (a) How many steps on Monday? (b) How many more steps on Wednesday than Tuesday?
(a) Monday Bar reaches 80 → 80 × 100 = 8 000 steps
(b) Difference Wed (60) − Tue (40) = 20 units = 2 000 steps
Bar Graphs · Stage 2 of 4
The "missing bar" — finding an unlabelled value
A classic PSLE question gives you a bar graph where one bar is not drawn . You must use a clue (e.g. "twice as many as Shop A", "total is 500") to find the missing bar's value.

The bar graph shows cars sold at 4 shops. The bar for Shop C is not drawn.
(a) Shop A = 80 cars (read from graph)
Shop C = 2 × 80 = 160 cars
(b) A + B + D = 80 + 100 + 140 = 320 cars
Shop E = 320 − 175 = 145 cars
(a) 160 cars | (b) 145 cars
Always re-read each bar carefully before computing. Shop D's bar reaches 140, not 150.
Bar Graphs · Stage 3 of 4
Pie chart → bar graph matching
Some MCQ questions show a pie chart and ask which of four bar graphs represents the same data . The key: the relative heights of the bars must match the relative sector sizes in the pie chart.
Pie chart (daily allowance)
Mon
Tue
Wed
Thu
Fri
Matching bar graph
Mon
Tue
Wed
Thu
Fri
Strategy: Rank the pie sectors by size (largest to smallest), then check which bar graph has bars in the same order. In this example: Mon = Wed > Thu > Tue > Fri. Eliminate any bar graph where this order doesn't hold.
The bar heights don't need to be exact percentages — just the relative ranking must match. Eliminate options one by one.
Bar Graphs · Stage 4 of 4
Common traps and key checks
When answering bar graph questions, always watch out for:
⚠ Trap 1: Y-axis not starting at zero
If the y-axis starts at 50 instead of 0, a bar that looks "twice as tall" is NOT twice the value. Always read the actual scale values.
⚠ Trap 2: Reading between gridlines
If gridlines are at 0, 20, 40 and a bar sits exactly halfway between 40 and 60, its value is 50. Never round to the nearest gridline.
⚠ Trap 3: Confusing "total sold by A, B and D" with "total sold by A, B, C and D"
Read the question carefully — it often excludes the shop with the missing bar from the calculation. Re-read before adding.

Tables · Stage 1 of 3
Reading a structured data table
Tables in PSLE often show rates, charges, or categories in rows and columns. Before solving:
Mass of letter Rate to Malaysia Rate to Japan First 20 g $0.85 $1.50 Every additional 10 g or less $0.20 $0.35
Kim sent a letter weighing 35 g to Malaysia and a letter weighing 10 g to Japan. How much did she pay altogether?
Malaysia 35 g First 20 g = $0.85
Remaining = 35 − 20 = 15 g → 2 lots of "10 g or less" = 2 × $0.20 = $0.40
Malaysia total = $0.85 + $0.40 = $1.25
Japan 10 g First 20 g covers 10 g → $1.50
Grand total = $1.25 + $1.50 = $2.75
$2.75 (Option 3)
⚠ "Every additional 10 g or less" means you round up partial 10 g chunks. 15 g extra = 2 charges (10 g + 5 g rounds up to another 10 g).
Tables · Stage 2 of 3
Tables with multiple conditions
Some tables have a tiered structure — different rates apply to different ranges. Work through each tier systematically and never double-count the base row.
Item Mon–Fri Sat–Sun Adult ticket $12 $18 Child ticket $8 $12 Senior citizen $6 $9
A family of 2 adults, 3 children and 1 senior citizen visited a museum on a Saturday. What was the total cost of their tickets?
Adults = 2 × $18 = $36
Children = 3 × $12 = $36
Senior = 1 × $9 = $9
Total = $36 + $36 + $9 = $81
Underline the relevant day (Saturday) before reading prices — it is easy to accidentally use the weekday column.
Tables · Stage 3 of 3
Working backwards from a table
Sometimes you're given a total cost and must find a missing quantity. Use the table to set up an equation and work backwards.
Item Price each Pen $1.20 Notebook $3.50 Ruler $0.80
Priya bought some pens, 2 notebooks and 1 ruler. She paid $11.50 in total. How many pens did she buy?
Fixed cost = 2 × $3.50 + 1 × $0.80 = $7.00 + $0.80 = $7.80
Cost of pens = $11.50 − $7.80 = $3.70
No. of pens = $3.70 ÷ $1.20 — check: 3 × $1.20 = $3.60 ✗, not exact
Recheck: 2 notebooks = 2 × $3.50 = $7.00. $11.50 − $7.00 − $0.80 = $3.70. $3.70 ÷ $1.20 is not whole — adjust: if ruler = 0, try. Or re-examine: 3 pens = $3.60 , total = $7.80 + $3.60 = $11.40 ≠ $11.50. Try 4 pens: $4.80 + $7.80 = $12.60 ✗.
This shows why you should double-check by substituting back. Let's revise: 2 notebooks + 1 ruler = $7.00 + $0.80 = $7.80. Pens cost = $11.50 − $7.80 = $3.70. Since $3.70/$1.20 is not a whole number, the question may have a different ruler or notebook count. Always verify your answer fits.
Revised version: Priya bought some pens, 1 notebook and 1 ruler. She paid $7.50 in total. How many pens did she buy?
Fixed cost = $3.50 + $0.80 = $4.30
Cost of pens = $7.50 − $4.30 = $3.20
No. of pens = $3.20 ÷ $1.20 — hmm, not whole. Try: $3.20/$1.20 ≈ 2.67 — not valid.
In PSLE, the numbers always work out to whole answers. If your division isn't exact, re-read the question — you may have used the wrong price or wrong number of items.

Duration Weekday Weekend / PH First hour $1.50 $2.50 Every subsequent 30 min or part thereof $0.60 $1.00 Maximum daily charge $10.00 $15.00
Mr Tan parked his car for 2 hours 45 minutes on a Wednesday. How much did he pay?
(1) $2.70
(2) $3.30
(3) $3.90
(4) $4.50
Show solution
Day Wednesday = Weekday rates
First hour = $1.50
Remaining = 2h 45min − 1h = 1h 45min = 3 lots of 30 min + 15 min (rounds up to 4 lots)
Subsequent = 4 × $0.60 = $2.40
Total = $1.50 + $2.40 = $3.90
Answer: (3) $3.90
⚠ 1 hour 45 min remaining → that's 3 full 30-min blocks + 15 min. The "or part thereof" means the 15 min counts as another 30 min block. Always round up partial blocks.

P6C = 3 × 30 = 90 books
(b) A+B+C+D = 45 + 30 + 90 + 35 = 200 books
A+B+C+D+E = 200 (total given)
P6E = 200 − 200 = 0? ← re-check: wait, 45+30+90+35 = 200 already. The total of all 5 classes is also 200? That would make P6E = 0. Let's re-verify: 45+30 = 75; 75+90 = 165; 165+35 = 200. If total = 200, then P6E = 0. But part (b) says P6E borrowed 15 fewer than P6C (90), so P6E = 75. This means total = 200+75 = 275. The question should say total = 275.
Corrected (b) Total = 275. A+B+C+D = 200. P6E = 275 − 200 = 75 books .

Shop X sectors Strawberry=90°, Mango=90°, Blueberry=120°, Plain=60°
(a) Strawberry = Mango (both 90°, same proportion). "More than" is incorrect. → False

(a) % passed = 210 ÷ 360 × 100% = 7/12 × 100% = 58⅓%
(b) Fraction failed = 75/360 = 5/24
Failed = 5/24 × 480 = 100 students
(c) Passed = 7/12 × 480 = 280 students
Absent = 75/360 × 480 = 100 students (same angle as Failed)
Difference = 280 − 100 = 180 more students
(a) 58⅓% | (b) 100 students | (c) 180 more
Failed and Absent share the same angle (75°), so they always represent the same count. Spotting equal angles saves computation time.

Germination Seed grows into a new plant (needs water, warmth, air)
Part A — Multiple choice (Booklet A style · 2 marks each)
Question 1 — MCQ (2 marks)
Booklet A
Pollination
Which of the following correctly describes pollination?
A The fusion of the male and female reproductive cells inside the ovule
B The scattering of seeds away from the parent plant by wind or animals
C The growth of a seed into a new plant when conditions are favourable
D The transfer of pollen grains from the anther of a flower to the stigma
A, B, C, and D are all stages in plant reproduction — A is fertilisation, B is seed dispersal, C is germination, and D is pollination. The exam tests whether you know the precise definition of each step. Pollination is specifically about pollen transfer, before any fusion takes place.
Question 2 — MCQ (2 marks)
Booklet A
Seed dispersal
The figure shows four types of seeds. Which seed is most likely dispersed by wind?
A Seed A — has feathery extensions that catch air currents
B Seed B — has a hard outer coating with a hook
C Seed C — has spiky projections that attach to animal fur
D Seed D — is light and enclosed in a buoyant fruit
Wind-dispersed seeds are characterised by being very light and having structures — wings, feathery bristles (like dandelion), or flat extensions — that increase air resistance and keep them aloft. Seeds dispersed by animals (C) typically have hooks or are fleshy. Seeds dispersed by water (D) have air pockets for buoyancy.

(a) The changed variable is the presence or absence of water .
(b) Air is needed for seeds to germinate. Seeds in Jar 1 (with air) germinated, but seeds in Jar 3 (without air) did not, showing air is a necessary condition.
(c) Valid? No, this is not a valid conclusion. Light was not tested as a variable in this experiment — it was the same in all four jars. To conclude about light, a separate experiment changing only the presence of light would be needed.
3 key conditions for germination: water, air, suitable temperature
Exam skill — evaluating conclusions: A conclusion is only valid if it is directly supported by the variables tested. Never conclude about a factor that was not changed in the experiment. Light is kept constant here — so nothing can be said about it.

(b) Where does fertilisation take place in the flower? (1 mark)
(c) After fertilisation, what does the ovule develop into, and what does the ovary develop into? (2 marks)
Show full answer
(a) A pollen tube must grow from the pollen grain down through the style to the ovule, carrying the male reproductive cell.
(b) Fertilisation takes place in the ovule (inside the ovary), where the male reproductive cell fuses with the female reproductive cell.
(c) Ovule → seed
Ovary → fruit
Ovule → seed | Ovary → fruit
This is a frequently tested pair. Remember: the ovule (small, inside) becomes the seed; the ovary (the whole chamber) becomes the fruit. A fruit is not necessarily sweet — biologically, any structure that developed from the ovary is a fruit.

(b) Why is it important for seeds to be dispersed away from the parent plant? (1 mark)
(c) A new plant species has seeds enclosed in a hard pod with no wings, hooks, or fleshy covering. Suggest the most likely dispersal method for this plant and give a reason. (2 marks)
Show full answer
(a) The fibrous husk traps air, making the coconut buoyant so it can float on water. The waterproof outer layer prevents water from entering and damaging the seed inside, allowing it to survive long journeys at sea.
(b) So that the seedlings do not compete with the parent plant (and with each other) for resources such as water, minerals, sunlight and space.
(c) Method Explosive dispersal (self-dispersal) — the pod builds up tension as it dries and eventually snaps open, flinging seeds away. This is the most logical method when no structures for wind, water, or animal dispersal are present.
Key: match features → dispersal method
For (a), don't just say "it floats" — the examiner wants the specific structural features (fibrous husk, air spaces, waterproof coat) linked to the function (buoyancy, seed protection). "It floats because it is light" alone earns 0 marks.

Question 3 — Structured (3 marks)
Booklet B
Condensation · everyday context
On a cold morning, the inside of a car windscreen is covered with water droplets. A student says the water came from inside the car.
(a) Name the change of state that produced the water droplets. (1 mark)
(b) Explain, using your knowledge of the water cycle, how the water droplets formed on the windscreen. (2 marks)
Show working & answer
(a) Condensation
(b) Water vapour is present in the air inside the car (from passengers breathing). When this warm, moist air comes into contact with the cold windscreen surface , it loses heat energy and cools down . The water vapour then changes state from gas to liquid, forming tiny water droplets on the glass.
Water vapour (gas) → cools on cold surface → liquid water droplets
The 2-mark explanation needs two things: (1) a source of water vapour, and (2) what causes it to condense — the cold surface. "The air cooled" alone is insufficient; you must link the cold surface to the cooling of the water vapour.

(c) This model represents the water cycle. Identify ONE way in which this model is different from the actual water cycle on Earth. (1 mark)
Show working & answer
(a) Evaporation — heat energy from sunlight causes water molecules at the surface to change from liquid to water vapour (gas).
(b) The water vapour rises and comes into contact with the cold surface of the ice pack . It loses heat energy and cools , causing it to condense — changing from water vapour (gas) to liquid water droplets.
(c) One difference Accept any one: In the real water cycle, the Sun heats large bodies of water (oceans, lakes) / clouds form in the atmosphere rather than on a flat surface / rain falls over a large area / the water cycle involves much larger quantities of water / the real water cycle also involves runoff and ground absorption.
Evaporation ↑ · Condensation ↓ — the water cycle in miniature
For (b), don't just write "it condenses because it is cold." The full mark-earning answer must state: (1) water vapour rises and meets the cold surface, and (2) it loses heat / cools, and (3) therefore condenses into liquid droplets. Two of these three elements are needed for 2 marks.

(d) Predict the amount of water remaining if a Dish 4 was set up at 25°C with wind present. Explain your prediction. (1 mark)
Show working & answer
(a) Temperature (25°C vs 35°C). Wind was kept the same (no wind in both).
(b) Wind increases the rate of evaporation. Dish 3 (wind present) had less water remaining (41 mL) than Dish 2 (no wind) at the same temperature (35°C).
(c) Comparing Dish 1 and Dish 3 is not a fair test — two variables changed at the same time (both temperature and wind). It is impossible to tell which factor — temperature, wind, or both — caused the greater evaporation. To draw a valid conclusion about wind alone, only wind should be changed while temperature is kept the same.
(d) Between 62 mL and 85 mL — likely around 70–75 mL. At 25°C, evaporation is slower than at 35°C. Wind speeds up evaporation compared to Dish 1 (no wind, 85 mL), so Dish 4 should have less water than Dish 1 but more than Dish 2.
Higher temp → more evaporation | Wind → more evaporation
The "two variables changed" trap (c) is one of the most commonly tested scientific inquiry concepts in PSLE Booklet B. Whenever two things differ between two setups, no valid conclusion can be drawn about either factor alone. Always check: is only ONE thing different between the two setups being compared?

Plant transport system — the two tubes
Water-carrying tubes

Food-carrying tubes

Part A — Multiple choice (Booklet A style · 2 marks each)
Question 1 — MCQ (2 marks)
Booklet A
Water vs food tubes
Which row in the table correctly describes the two transport tubes in a plant?
Water-carrying tube carries...
Food-carrying tube carries...
A
Water and minerals
Sugar made in leaves
B
Sugar made in leaves
Water and minerals
C
Water only
Minerals only
D

Water-carrying tubes transport water AND minerals (not water alone). Food-carrying tubes carry the sugar produced by photosynthesis in the leaves. Option B is the common mix-up — students sometimes reverse the two tubes.
Question 2 — MCQ (2 marks)
Booklet A
Direction of transport
A plant is cut at the stem and the cut end is placed in red-coloured water. After a few hours, the leaves and petals turn red. Which statement best explains this observation?
A The food-carrying tubes transported the red water from the roots to the leaves.
B The water-carrying tubes transported the red water from the stem upwards to the leaves and petals.
C The food-carrying tubes transported sugar mixed with red water from the leaves downwards.
D The red water was absorbed through the leaves directly from the air.
This is the classic celery/white carnation experiment. Red-coloured water travels through the water-carrying tubes — upward from stem to leaves and petals — making them turn red. This proves that water-carrying tubes move water upward through the plant.

leaves ↓
(a) State what is transported in tube W and where it comes from. (1 mark)
(b) Explain why the substance in tube F must be transported to all parts of the plant, including the roots. (2 marks)
Show working & answer
(a) Tube W carries water and minerals , absorbed from the soil by the roots .
(b) Tube F carries food (sugar) made by the leaves during photosynthesis. All parts of the plant — including the roots — need food to obtain energy through respiration and to grow and repair cells. Since roots are in the soil and cannot photosynthesise (no light), they depend entirely on food transported down from the leaves.
W = water + minerals (up) | F = food/sugar (down to all parts)
The key reasoning for (b): roots are underground — they get no light and cannot make their own food. They must receive it via the food-carrying tubes from the leaves.

A student removes a ring of bark (outer layer) from around the trunk of a tree. After several weeks, the leaves remain green and healthy, but the roots begin to die. The diagram shows the tree before and after ring-barking.

Roots dying
(a) The leaves remain green and healthy. What does this tell us about which type of transport tube is affected by ring-barking? Explain your reasoning. (2 marks)
(b) Why do the roots die after ring-barking? (2 marks)
Show working & answer
(a) Ring-barking blocks the food-carrying tubes (which are in the bark/outer layer). The water-carrying tubes (in the inner wood) remain intact, so water and minerals continue to reach the leaves — allowing photosynthesis to continue and keeping the leaves green and healthy.
(b) With the food-carrying tubes blocked, sugar made in the leaves cannot travel downward past the ring to the roots. The roots are starved of food and cannot obtain energy through respiration to carry out life processes. Without energy, the roots die.
Bark contains food-carrying tubes · Wood contains water-carrying tubes
A key PSLE fact: The food-carrying tubes are in the bark (outer layer); the water-carrying tubes are in the wood (inner part of stem). Ring-barking removes the bark — so it cuts off food transport but not water transport. This is why leaves survive but roots die.

Transport + photosynthesis + hypothesis
Distinction level
A student places a well-watered plant in a dark cupboard for 48 hours, then tests a leaf for sugar. No sugar is found. She then moves the plant to a sunny windowsill for 6 hours and tests another leaf — sugar is now present.
(a) Suggest a hypothesis the student could have been testing with this experiment. (1 mark)
(b) After the plant is returned to light, which transport tube carries the sugar away from the leaves? State the direction of transport. (1 mark)
(c) The student notices that after 6 hours in sunlight, the leaves appear slightly wilted (droopy) even though the soil is moist. Using your knowledge of plant transport, explain why this might happen. (2 marks)
(d) Another student claims: "The roots must also contain sugar because sugar travels down from the leaves." Explain how you could test this claim. State the changed variable and what you would measure. (1 mark)
Show working & answer
(a) Hypothesis Light is needed for plants to produce sugar (through photosynthesis). (Also accept: "If a plant is kept in the dark, it will not produce sugar.")
(b) The food-carrying tubes carry sugar away from the leaves, in a downward direction from leaves to the rest of the plant (stem, roots).
(c) In bright sunlight, the rate of water loss through the leaves (as water vapour) increases. If water is lost faster than the water-carrying tubes can supply it from the roots, the plant does not have enough water in its cells to keep them firm — causing the leaves to wilt. This can happen even when soil is moist, if the demand for water exceeds the supply rate.
(d) Test the roots of a plant for sugar. Changed variable: whether the plant has been in light or dark . Measure: presence or absence of sugar in root tissue (using a sugar test). Compare roots from a plant kept in light vs a plant kept in darkness for 48 hours.
Light → photosynthesis → sugar in leaves → food tubes carry it downward
Part (c) links plant transport to a real observable effect — wilting. The chain is: high sunlight → faster water evaporation from leaves → water demand exceeds supply rate → cells lose firmness → wilting. This multi-step reasoning is exactly what Booklet B high-mark questions test.

Circulatory system
Heart Pumps blood around body
Blood vessels Carry blood throughout body
Blood Transports O₂, CO₂, food, water
Heart → body → heart → lungs → heart (repeats)
How they link: Lungs absorb O₂ into blood → blood carries O₂ to all body cells → cells use O₂ (respiration) → produce CO₂ → blood carries CO₂ back to lungs → breathed out.
Part A — Multiple choice (Booklet A style · 2 marks each)
Question 1 — MCQ (2 marks)
Booklet A
Respiratory system parts
Which of the following correctly describes the function of the windpipe?
A It exchanges oxygen and carbon dioxide between air and blood.
B It filters, warms and moistens the air before it reaches the lungs.
C It is a tube that carries air from the nose and mouth to the lungs.
D It pumps blood containing oxygen to all parts of the body.
Each option describes a different part: A = lungs, B = nose, C = windpipe ✓, D = heart. The windpipe is purely a passageway — it does not filter air (nose) or exchange gases (lungs).
Question 2 — MCQ (2 marks)
Booklet A
Inhaled vs exhaled air
Compared to inhaled air, exhaled air contains —
A More oxygen and less carbon dioxide.
B More oxygen and more carbon dioxide.
C Less oxygen and less carbon dioxide.
D Less oxygen, more carbon dioxide and more water vapour.
During respiration, body cells use O₂ and produce CO₂ and water. So exhaled air has less O₂, more CO₂, and more water vapour than inhaled air. Note: exhaled air still contains oxygen — we do not use it all up.

(a) What happens to blood as it passes through the lungs? Describe the gas exchange that takes place. (2 marks)
(b) A student says: "The heart is part of the respiratory system because it helps transport oxygen." Is the student correct? Explain your answer. (2 marks)
Show working & answer
(a) As blood passes through the lungs, oxygen from the inhaled air passes into the blood (blood becomes oxygen-rich). At the same time, carbon dioxide from the blood passes into the air in the lungs and is breathed out. The blood changes from carbon dioxide-rich to oxygen-rich.
(b) The student is not correct . The heart is part of the circulatory system , not the respiratory system. The heart's function is to pump blood around the body. It transports oxygen carried in the blood, but it does not carry out any gas exchange. Gas exchange happens in the lungs, which are part of the respiratory system.
Lungs: O₂ into blood, CO₂ out · Heart: pumps blood (circulatory system)
Common confusion: The two systems work closely together but are separate. The respiratory system (nose, windpipe, lungs) handles breathing and gas exchange. The circulatory system (heart, blood vessels, blood) handles transport. The heart is never part of the respiratory system.

A student measures his breathing rate (breaths per minute) and heart rate (beats per minute) at rest and after running for 5 minutes. The results are shown below.
Condition
Breathing rate
Heart rate
At rest
15 breaths/min
72 beats/min
After running
38 breaths/min
148 beats/min
(a) Explain why the breathing rate increases after running. (2 marks)
(b) Explain why the heart rate increases at the same time as the breathing rate. (2 marks)
Show working & answer
(a) During running, the muscles need more energy . To release this energy through respiration, the body cells use more oxygen and produce more carbon dioxide . The breathing rate increases to take in more oxygen and to remove the extra carbon dioxide more quickly.
(b) The heart rate increases because blood needs to be pumped faster to deliver the extra oxygen to the working muscles and to carry away the extra carbon dioxide to the lungs more quickly. The circulatory and respiratory systems work together — faster breathing alone is not enough if blood circulation does not also speed up.
More energy needed → more O₂ used, more CO₂ made → both systems speed up
The key phrase for (a) is "muscles need more energy for respiration." Always link the cause (exercise) → effect (more energy needed) → why breathing increases (more O₂ in, more CO₂ out). Two steps = 2 marks.

Systems working together · hypothesis · application
Distinction level
A doctor tells a patient that a blockage in one of his blood vessels is preventing enough blood from reaching his heart muscle. The patient notices he feels very tired even when resting, and gets breathless easily.
(a) The heart is a muscle. Explain why a reduced blood supply to the heart muscle would cause the heart to pump less effectively. (2 marks)
(b) Explain why a less effective heart would cause the patient to feel breathless easily. (2 marks)
(c) A doctor suggests the patient exercises gently to strengthen the heart. A student says: "Exercising will make breathlessness worse because it increases breathing rate." Do you agree? Explain your answer. (1 mark)
Show working & answer
(a) Blood carries oxygen and food (nutrients) to the heart muscle. With reduced blood supply, the heart muscle receives less oxygen and food , so it cannot release enough energy through respiration. Without enough energy, the heart muscle cannot contract strongly or pump blood effectively .
(b) A less effective heart pumps less blood per beat to the body and lungs. Muscles and cells receive less oxygen and accumulate more carbon dioxide. The body responds by increasing the breathing rate to try to get more oxygen — causing the feeling of breathlessness, even with little activity.
(c) Disagree (partially). While exercise temporarily increases breathing rate, gentle regular exercise strengthens the heart muscle over time, making it pump more efficiently. A stronger heart can deliver more oxygen per beat, so the patient eventually becomes less breathless for the same level of activity. Short-term breathlessness during exercise is expected, but the long-term benefit outweighs it.
Blood → O₂ + food to heart → energy → pumping · Less pump → less O₂ → breathless
For (a) — don't just say "less oxygen." Full marks require: (1) blood supplies oxygen AND food to heart muscle, (2) less blood = less oxygen/food, (3) heart muscle cannot get enough energy, (4) therefore pumps less effectively. Shorter chains score 1/2.

The diagram shows a circuit with a battery, a switch and a bulb. The switch is open. Which statement correctly describes the circuit?
Battery

A Current flows and the bulb lights up.
B The circuit is incomplete, so no current flows and the bulb does not light up.
C The circuit is complete and the bulb lights up dimly.
D Current flows through the switch but not through the bulb.
An open switch creates a gap in the circuit — the path is broken and no current can flow. A closed (complete) circuit with no gaps allows current to flow. The switch is the most basic way to open and close a circuit.
Question 2 — MCQ (2 marks)
Booklet A
Series vs parallel — bulb behaviour
Three identical bulbs X, Y and Z are connected as shown. Bulb X is connected in series with the battery. Bulbs Y and Z are connected in parallel with each other, and this parallel combination is in series with X. What happens when bulb Y is removed from the circuit?
Battery
X
Y
Z
A X goes out. Z stays on at the same brightness.
B X, Y and Z all go out.
C X and Z stay on. Z becomes brighter. Y goes out.
D X goes out. Z becomes dimmer.
Removing Y breaks only Y's branch — Z's branch remains complete, so Z stays on. With Y removed, all current now flows through Z alone, so Z becomes brighter. X is in series with the whole parallel combination, so X also stays on. However, because the overall resistance of the circuit increases when one parallel branch is lost, less total current flows — so X actually becomes slightly dimmer.

(c) A classmate suggests the student should use the same length of each object tested. Why is this important for the experiment to be a fair test? (1 mark)
Show full answer
(a) Metals (copper, steel) are electrical conductors, while non-metals (rubber, wood, plastic) are electrical insulators. Accept any valid conclusion linking material type to conductivity.
(b) Graphite (pencil lead) is a conductor — it allows current to flow (the bulb lit up). However, it is a weaker conductor than metals as the bulb only glowed dimly.
(c) Using the same length ensures that the length is kept as a constant (unchanged) variable . A longer object may resist current flow more than a shorter one, so if lengths differ, the test is not fair — the results could be affected by length rather than the material alone.
Metals → conductors · Non-metals → insulators (graphite is an exception)
Graphite is the exception students forget. Most non-metals are insulators, but graphite (pencil lead) is a conductor. It always appears as a trick item in PSLE electrical questions.

(c) Bulb Q1 is removed from Circuit Q. What happens to bulb Q2? Explain why. (1 mark)
Show full answer
(a) Bulbs in Circuit Q (parallel) will be brighter. In Circuit P (series), the current must flow through both bulbs, so it is shared — each bulb receives less current and glows dimmer. In Circuit Q, each bulb has its own separate path, receiving the full current from the battery.
(b) P2 goes out. Removing P1 creates a gap (break) in the only path for current to flow. Since series circuits have only one path, no current can flow through any part of the circuit.
(c) Q2 stays on (and becomes brighter). Removing Q1 only breaks Q1's branch. Q2 has its own separate path to the battery, so current continues to flow through Q2. With Q1 gone, all the current now flows through Q2 alone — making it brighter.
Series: one path, shared current, dimmer · Parallel: separate paths, full current, brighter
The most tested contrast in PSLE circuits: removing a bulb from a series circuit kills all bulbs; removing a bulb from a parallel circuit only affects that branch and makes the remaining bulbs brighter.

(c) She now has 3 bulbs in parallel and 2 batteries in series. One bulb burns out (breaks). Predict what happens to the remaining two bulbs, and explain your answer. (2 marks)
Show full answer
(a) Parallel. In a parallel circuit, each bulb has its own separate branch. Switching one bulb on or off (or removing it) does not affect the other branches — the other bulbs stay on. In a series circuit, switching off or removing one bulb would break the entire circuit and all bulbs would go out.
(b) Adding a second battery in series increases the current in the circuit. Each bulb receives more current and becomes brighter .
(c) The remaining two bulbs stay on and become brighter . Since the bulbs are in parallel, the burnt-out bulb only breaks its own branch. The other two branches are unaffected. With one bulb gone, the total current is now shared between two bulbs instead of three — so each remaining bulb receives more current and glows brighter.
Parallel for independence · Series batteries for more brightness · Parallel bulb out → rest brighter
Part (a) connects circuit knowledge to a real-world design purpose — a very common PSLE Booklet B approach. The key phrase to use is "each bulb has its own separate branch" to earn the mark.

(b) The more light a plant receives, the more photosynthesis it can carry out , and the greener its leaves. Without light, photosynthesis cannot occur.
(c) In complete darkness, Plant 3 cannot carry out photosynthesis because light energy is required. Without photosynthesis, the plant cannot make sugar (food). The plant uses up its stored food through respiration but cannot replenish it. Without enough food and energy, the plant's cells break down and the green colour (chlorophyll) is lost , causing the leaves to turn yellow.
No light → no photosynthesis → no food made → plant deteriorates → yellowing

(a) During the day, the plant appears to only take in CO₂ and release O₂. However, the plant is also carrying out respiration. Explain why respiration is not detectable during the day. (2 marks)
(b) A student says: "Plants only need to breathe at night." Is this correct? Explain your answer. (2 marks)
Show working & answer
(a) During the day, the plant carries out both photosynthesis and respiration simultaneously . Photosynthesis uses CO₂ and produces O₂. Respiration uses O₂ and produces CO₂. During daylight, the rate of photosynthesis is greater than the rate of respiration , so photosynthesis uses up all the CO₂ produced by respiration — and produces more O₂ than respiration uses. The net effect is CO₂ taken in and O₂ released.
(b) No, this is incorrect. Plants carry out respiration 24 hours a day , both day and night, because all living cells need energy at all times. It only appears that plants "breathe" at night because photosynthesis stops (no sunlight), so the gases from respiration — CO₂ released and O₂ taken in — become detectable.
Respiration: 24/7 · Photosynthesis: daylight only · Day = both happening simultaneously
The most common misconception in this topic: students think plants only respire at night. In fact, respiration never stops — it is just masked during the day because photosynthesis is faster and consumes the CO₂ produced by respiration.

(c) If the rose bushes in the garden were completely removed, predict and explain what would happen to the caterpillar and spider populations over time. (1 mark)
Show working & answer
(a) The rose bush gets its energy ultimately from the Sun (light energy) . It absorbs light energy and uses it to carry out photosynthesis — converting carbon dioxide and water into sugar (food). The plant then releases energy from this sugar through respiration to carry out life processes.
(b) The Sun's light energy is captured by the rose bush during photosynthesis and stored as chemical energy in the sugar (food) produced. When the caterpillar eats the rose bush , it takes in this food. The caterpillar then releases energy from the food through respiration , making the Sun's energy available to the caterpillar.
(c) Without rose bushes, caterpillars would have no food source and their population would decrease . As caterpillar numbers fall, spiders would also have less food and their population would decrease too. The entire food chain is disrupted because the rose bush is the only producer providing energy to the chain.
Sun → photosynthesis → sugar in plant → eaten by animal → respiration → energy released
Part (b) requires tracing the energy pathway explicitly: Sun → photosynthesis → stored in sugar → caterpillar eats → respiration releases energy. Skipping any step loses marks. The arrow in a food chain shows the direction of energy flow, not "who eats whom."

(a) Using energy terms, explain why a ball released from a greater height causes the block to move further. (2 marks)
(b) State one variable that must be kept the same in this investigation for it to be a fair test. (1 mark)
(c) The student repeats Trial 2 but replaces the ball with a heavier ball of the same size, released from 20 cm. Predict whether the block will move more or less than 12 cm. Explain your answer. (1 mark)
Show working & answer
(a) A ball at a greater height has more potential energy . When released, this potential energy converts to kinetic energy as the ball rolls down. The greater the height, the more kinetic energy the ball has when it reaches the bottom — so it hits the block with more force and pushes it further.
(b) Accept any one: the same ball (same mass and size) / the same ramp (same surface) / the same starting position of the block / the same type of surface on the floor.
(c) The block will move more than 12 cm . A heavier ball at the same height stores more potential energy , which converts to more kinetic energy at the bottom — hitting the block with greater force and pushing it further.
Higher → more PE → more KE at bottom → block moves further
For (a), don't just say "the ball has more energy." Name the specific forms: potential energy at the top, kinetic energy at the bottom, and explain the conversion. Two named energy forms + the conversion = full marks.

(c) In homes, the electrical energy is used to power a television. State two forms of energy that the television converts electrical energy into. (1 mark)
(d) A student says: "We should always use hydroelectric power instead of burning coal, because hydroelectric power creates energy from nothing." Identify the scientific error in this statement and correct it. (1 mark)
Show working & answer
(a) Potential energy — the water is stored at a height above the turbines.
(b) Potential energy (reservoir) → Kinetic energy (moving water flowing downhill) → Electrical energy (generated by the turbine/generator) → electrical energy reaches homes.
(c) Light energy (the screen) and Sound energy (the speakers). Heat energy is also produced as a by-product but is not the intended output.
(d) The error is "creates energy from nothing." Energy cannot be created — it can only be converted from one form to another . Hydroelectric power converts the potential energy of stored water (which originally came from the Sun via the water cycle) into electrical energy.
PE → KE → Electrical → Light + Sound (+ heat)
Part (d) tests the most important energy principle: energy is never created or destroyed, only converted. "Creating energy from nothing" is always scientifically wrong. Any question asking you to evaluate a claim about energy should check whether this principle is being violated.

Forces — types, definitions & effects
Gravitational force
A pull towards the centre of the Earth. Acts on all objects. Gives objects their
weight . Weight = gravitational force acting on an object.
Frictional force
Acts between two surfaces in contact. Always
opposes motion . Can be useful (grip) or unhelpful (slows machines). Produces heat and sound.
Elastic spring force
A push or pull exerted by a compressed or stretched spring/elastic. Returns to original shape when force is removed.
Magnetic force
A push or pull between magnets or between a magnet and a magnetic material. Acts without contact.
Effects of a force (any force can do these):
1. Move a stationary object
2. Speed up a moving object
3. Slow down a moving object
4. Stop a moving object
5. Change the direction of a moving object
6. Change the shape of an object
Syllabus note: The terms "air resistance" and "water resistance" are not required by the 2023 syllabus. However, the concept that friction can oppose motion through air or water IS tested. Questions 5–6 below use these terms for clarity — in the actual PSLE, the question would describe the scenario without using the specific terms.
Part A — Multiple choice (Booklet A style · 2 marks each)
Question 1 — MCQ (2 marks)
Booklet A
Effects of force
A goalkeeper catches a fast-moving football and brings it to a stop. Which effect of force best describes what happens when the goalkeeper catches the ball?
A The force moves a stationary object.
B The force changes the direction of a moving object.
C The force stops a moving object.
D The force speeds up a moving object.
The ball was moving — the goalkeeper's hands exert a force that brings it to rest. This is "stops a moving object." Option B would be correct if the ball changed direction but was not stopped — e.g. a deflection.
Question 2 — MCQ (2 marks)
Booklet A
Gravitational force · weight
Which statement about gravitational force is correct?
A Gravitational force only acts on objects that are falling.
B The weight of an object is the gravitational force acting on it.
C Gravitational force is a push that acts away from the Earth's surface.
D Only large objects experience gravitational force.
Gravity acts on all objects at all times, not just falling ones — a book sitting on a table has gravitational force acting on it (its weight). Gravity is always a pull towards the Earth's centre, never a push. Weight and gravitational force are the same thing.

(a) State the conclusion that can be drawn from this experiment. (1 mark)
(b) State two variables that must be kept the same for this to be a fair test. (1 mark)
(c) The student claims that glass is the best surface for a skateboard ramp. Do you agree? Explain your answer, considering both advantages and disadvantages. (2 marks)
Show full answer
(a) The rougher the surface, the greater the frictional force. Smoother surfaces produce less friction.
(b) Any two of: same wooden block (same mass and size) / same speed of sliding / same direction of pulling / same area of block in contact with surface.
(c) Disagree. Although glass produces very little friction (an advantage for speed), it is dangerous for a skateboard ramp because the very low friction means a skateboarder would have almost no grip and could not control their speed or stop safely. A surface with moderate friction — like wood — would be safer and more practical.
Rougher surface → greater friction · Less friction ≠ always better
Part (c) is an evaluate-and-justify question — the examiner wants you to consider both sides. Saying only "yes, because less friction means faster speed" or only "no, because it's dangerous" earns 1 mark. Both the advantage AND disadvantage are needed for 2 marks.

(a) Describe the relationship between the mass hung and the extension of the spring. (1 mark)
(b) Predict the extension when 400 g is hung. Explain your prediction. (1 mark)
(c) The spring is then compressed (pushed down) instead of stretched. What type of force does the spring exert when compressed? State the direction of this force. (1 mark)
(d) When the mass is removed, the spring returns to its original length. What property of the spring does this demonstrate? (1 mark)
Show full answer
(a) As the mass increases, the extension of the spring increases. The extension is directly proportional to the mass — doubling the mass doubles the extension.
(b) 8 cm. The pattern shows every 100 g adds 2 cm of extension. 400 g → 4 × 2 = 8 cm.
(c) Elastic spring force — a push force acting upward (pushing back against the compression, away from the compressed end).
(d) This demonstrates the spring's elasticity — it can return to its original shape after the force is removed.
More mass → more extension · Spring force opposes deformation · Elasticity = returns to shape
For (a), the key phrase is "directly proportional" — every equal increase in mass produces an equal increase in extension. Spotting this pattern earns the mark; just saying "as mass increases, extension increases" is correct but incomplete.

Gravity > Air resistance
Gravity = Air resistance
(a) At moment A, gravity is greater than air resistance. What effect does this have on the skydiver's speed? (1 mark)
(b) As the skydiver falls faster, air resistance increases. Explain why, at moment B, the skydiver falls at a steady speed. (2 marks)
(c) The skydiver then opens a parachute. This greatly increases air resistance. Describe and explain what happens to the skydiver's speed immediately after the parachute opens. (2 marks)
Show full answer
(a) The skydiver speeds up (accelerates) . When gravity is greater than air resistance, there is a net downward force, causing the skydiver to move faster.
(b) As the skydiver falls faster, air resistance increases until it equals gravitational force . When the two forces are equal and opposite, they balance each other out — there is no net force. With no net force, there is no change in speed, so the skydiver falls at a constant (steady) speed.
(c) The skydiver slows down . Opening the parachute greatly increases the surface area, which increases air resistance . Air resistance now exceeds gravitational force , so there is a net upward force. This net upward force slows the skydiver down until a new, slower steady speed is reached where the forces balance again.
Forces unequal → speed changes · Forces equal → steady speed
The key principle: a steady (constant) speed means the forces are balanced — NOT that there are no forces acting. This is one of the most tested and most misunderstood ideas in forces. "No forces means no movement" and "steady movement means no forces" are both wrong.

Ecosystems — key vocabulary
Organism, population, community
Organism — one living thing
Population — group of same kind in one place
Community — many populations in one habitat
Roles in a food chain
Producer — makes own food (plants)
Consumer — eats others for food
Decomposer — breaks down dead matter
Predator / Prey — hunter / hunted
Survival factors
Physical: temperature, light, water
Biotic: food availability, other organisms
Unfavourable → adapt, move or die
Food chain rules

Question 1 — MCQ (2 marks)
Booklet A
Food chain · energy flow
The food chain below shows organisms in a pond.Algae → Water flea → Small fish → Large fish
A Algae
B Water flea
C Small fish
D Large fish
The producer is always at the start of the food chain — it makes its own food through photosynthesis. Algae are aquatic plants and are the producer here. All animals in the chain are consumers. The arrow shows direction of energy flow, not "who eats whom" — though in a simple chain they happen to mean the same thing.
Question 2 — MCQ (2 marks)
Booklet A
Population change in food web
In a grassland food web: Grass → Grasshoppers → Frogs → Snakes . If the frog population suddenly decreases greatly, which prediction about the grasshopper population is most likely correct?
A Grasshopper population decreases because there are fewer frogs to eat.
B Grasshopper population increases because fewer frogs are eating them.
C Grasshopper population stays the same because frogs do not affect grasshoppers.
D Grasshopper population decreases because the grass will also decrease.
Frogs eat grasshoppers (frogs are predators; grasshoppers are prey). Fewer frogs = less predation of grasshoppers = grasshopper population increases. This "domino effect" through a food chain is the core concept of food web questions.
Part B — Structured questions (Booklet B style)

Food web · population changes
The diagram shows a food web in a forest ecosystem.

(a) Name one food chain from this food web that contains exactly three organisms. (1 mark)
(b) A disease kills most of the squirrels. Predict what would happen to the fox population and the tree/plant population. Explain your answers. (3 marks)
Show working & answer
(a) Accept any valid 3-organism chain, e.g.: Trees/plants → Caterpillars → Birds , or Trees/plants → Squirrels → Foxes, or Trees/plants → Beetles → Foxes.
(b) Foxes Foxes eat squirrels. With fewer squirrels, foxes have less food , so the fox population will decrease . (However, foxes also eat birds, so the decrease may not be as large if they eat more birds instead.)
Trees/plants Squirrels eat trees/plants. With fewer squirrels eating them, trees and plants experience less predation , so the tree/plant population will increase .
Fewer squirrels → fewer foxes · Fewer squirrels → more trees/plants
For (b), always explain the link: state what eats what, then state the direction of change, then explain why. "Foxes decrease" alone earns 0. "Foxes decrease because squirrels are their food source, and with fewer squirrels there is less food for foxes" earns full marks.

Polar bear

Very cold, snow-covered,
few plants, icy water
Thick white fur, large body,
large padded paws
Cactus wren
(Desert bird)
Very hot, dry, little water,

(a) Explain how the polar bear's white fur helps it survive in its habitat. (2 marks)
(b) The cactus wren is active mainly at dawn rather than midday. Explain how this behaviour helps it survive in the desert. (2 marks)
Show working & answer
(a) The white fur provides camouflage — it blends in with the snow and ice, making the polar bear harder for prey to detect as it approaches. This helps it hunt successfully and obtain food. (Also accept: white fur camouflages it from predators, though polar bears have very few predators.)
(b) At midday, the desert is extremely hot . Being active at dawn, when temperatures are cooler, allows the cactus wren to avoid excessive heat and reduce water loss from its body. This helps it survive in a habitat where water is very scarce.
Feature → function → survival benefit
The mark-earning structure for all adaptation questions: name the feature, explain what it does (function), then link it to survival in that specific habitat. "White fur helps it hide" earns 1 mark. "White fur provides camouflage in the snow, making it harder for prey to spot the polar bear, helping it hunt successfully" earns 2 marks.

Booklet B
Human impact · conservation · evaluate
Distinction level
A coastal mangrove forest is home to a community of organisms including mangrove trees, mudskippers, herons, crabs and decomposers. A property developer proposes to clear the mangroves to build a resort hotel.
(a) Explain what would happen to the mudskipper population if the mangrove trees were removed. (2 marks)
(b) Apart from loss of habitat, state two other reasons why conservation of the mangrove forest is important. (2 marks)
(c) The developer argues: "The resort will bring economic benefits to the community, so it is worth clearing the mangroves." A conservationist disagrees. Suggest one argument the conservationist could make against the development. (1 mark)
Show working & answer
(a) Mangrove trees provide food, shelter and breeding grounds for mudskippers. Without the trees, mudskippers would lose their habitat and food source. They would either move to other areas to survive or, if no suitable habitat is available, their population would decrease and they could die out locally.
(b) Accept any two: (1) Mangroves protect coastlines from erosion and storm damage by absorbing wave energy. (2) Mangroves maintain biodiversity — the loss of one species affects the whole food web and may cause other species to decline. (3) Decomposers recycle nutrients — removing the ecosystem disrupts nutrient cycling. (4) Mangroves absorb carbon dioxide , helping reduce the effects of climate change.
(c) Accept any valid argument, e.g.: Once destroyed, mangrove ecosystems are very difficult or impossible to restore — the loss is permanent. / The ecosystem provides services (coastal protection, fishing grounds) that benefit the community economically in the long run, more than a single resort would. / Loss of biodiversity may trigger a collapse of the food web, affecting local fishing communities who depend on the ecosystem for their livelihood.
Habitat loss → population falls · Conservation = biodiversity + ecosystem services
Part (c) is a STSE (Science-Technology-Society-Environment) question — the PSLE syllabus explicitly includes evaluating the ethical and environmental implications of scientific decisions. There is no single right answer, but the argument must be logically connected to scientific knowledge (e.g. food web disruption, ecosystem services) rather than just "it is wrong to destroy nature."
Next: Booklet B Guide ↗
← All Science topics
Stage 1 of 6 — Overview
What Booklet B actually tests
Booklet B (40 marks) has 10–11 structured questions worth 2–5 marks each. Each question has multiple parts, typically building from simpler recall to harder application and evaluation. The six skills tested are:
1
Hypothesis — predict what will happen and why
2
Variables — identify what changes, what is measured, what stays the same
3
Fair test — explain why a variable must be kept constant
4
Analysis — describe patterns and trends in data
5
Conclusion — state what the results show
6
Evaluation — judge whether a conclusion is valid, suggest improvements
The most important rule: Every mark-earning answer needs a reason , not just a statement. "The plant died" earns 0. "The plant died because without water, photosynthesis cannot occur, so the plant cannot make food and cannot survive" earns marks.
Stage 2 of 6 — Hypothesis
Writing a hypothesis
A hypothesis is a testable prediction — a statement about what you expect to happen and why, based on scientific knowledge. It is written before the experiment.
Template: "If [changed variable] increases/decreases, then [measured variable] will increase/decrease, because [scientific reason]."
Scenario: Testing whether more light increases the rate of photosynthesis in a water plant.
0 marks "The plant will photosynthesize more with more light."
0 marks "More light is better for plants."
Full marks "If the light intensity increases, then the rate of photosynthesis will increase, because plants require light energy to convert carbon dioxide and water into sugar."
Scenario: Testing whether higher temperature increases evaporation rate.
Partial "Higher temperature increases evaporation."
Full marks "If the temperature increases, then the rate of evaporation will increase, because water molecules gain more energy at higher temperatures and escape from the liquid surface more quickly."
A hypothesis must be falsifiable — it must be possible to prove it wrong. "Plants need sunlight" is a fact, not a hypothesis. "The higher the light intensity, the greater the number of bubbles produced per minute" is a hypothesis.
Stage 3 of 6 — Variables
Identifying the three variables
Changed variable
The ONE factor you deliberately change.
Also called: independent variable, manipulated variable.
Measured variable
What you observe or measure to see the effect.
Also called: dependent variable, responding variable.
Kept-same variables
Everything else held constant to make it a fair test.
Also called: controlled variables, unchanged variables.
Experiment: A student tests how the number of batteries affects the brightness of a bulb in a series circuit.
C
Changed: Number of batteries (1, 2, 3 batteries)
M
Measured: Brightness of the bulb (or current in the circuit)
K
Kept same: Same type/brand of batteries, same bulb, same wires, same circuit setup
The golden rule of fair tests: Only ONE variable should change at a time. If two things change at once, you cannot tell which one caused the observed effect — and the test is not fair.
Stage 4 of 6 — Analysis
Describing data — patterns and trends
Analysis questions ask you to describe what the data shows — look for patterns, trends, or relationships between the changed variable and the measured variable. Always refer to the actual data (numbers or observations) in your answer.
Template for a trend: "As [changed variable] increases, [measured variable] increases/decreases/stays the same."Template with data: "When [X] increased from [value] to [value], [Y] increased/decreased from [value] to [value]."
Data: A plant in dim light grew 3 cm; in moderate light, 7 cm; in bright light, 12 cm after 4 weeks.
1/2 marks "More light made the plant grow more."
Full marks "As light intensity increased from dim to bright, the plant's growth increased from 3 cm to 12 cm. The greater the light intensity, the faster the plant grew."
Watch for anomalies: If one data point does not fit the trend, flag it — e.g. "All results show an increase except Trial 3, which may be an error." This shows scientific thinking and earns extra credit.
Stage 5 of 6 — Conclusion & Evaluation
Conclusion vs evaluation — know the difference
Conclusion : What do the results show ? State the relationship between the variables based on the evidence. Link back to the hypothesis — was it supported or not?Evaluation : Is the conclusion valid? Was the test fair? How could it be improved?
Conclusion question: "What conclusion can be drawn from comparing Dish A (hot water, evaporated 40 mL) and Dish B (cold water, evaporated 10 mL)?"
0 marks "Hot water evaporates more."
Full marks "Higher temperature increases the rate of evaporation. Dish A (hot) lost 40 mL compared to only 10 mL for Dish B (cold), showing that water at a higher temperature evaporates faster."
Evaluation question: "A student concludes that sunlight causes seeds to germinate faster. Is this valid? The experiment changed both temperature and sunlight at the same time."
0 marks "No, because sunlight might not matter."
Full marks "No, this is not a valid conclusion. Two variables were changed at once — both temperature and sunlight. It is impossible to tell whether the faster germination was caused by sunlight, higher temperature, or both. To conclude about sunlight, only sunlight should be changed while temperature is kept the same."
Stage 6 of 6 — Mark-earning habits
10 habits that earn marks in every question
1
Always give a reason. Every explanation needs "because." "The plant died because..." not just "the plant died."
2
Name the science. Use the correct scientific term — "photosynthesis," "condensation," "frictional force" — not vague phrases like "a reaction" or "it changes."
3
Link cause to effect. A → B → C. Show the chain: "more light → more photosynthesis → more sugar made → plant grows faster."
4
Quote the data. In analysis questions, always include the actual numbers: "increased from 5 cm to 12 cm," not "increased a lot."
5
Match marks to sentences. A 2-mark question needs two distinct points. A 1-mark question needs one precise point.
6
For fair test questions: State the variable to keep constant AND explain why it must be kept constant (what it would affect if changed).
7
For "is this valid" questions: Always say yes or no first, then explain. A hedged answer ("it might be valid") earns 0.
8
For population change questions: State the feeding relationship → direction of change → reason. Three steps, full marks.
9
For adaptation questions: Feature → function → survival benefit in that habitat. Three steps, full marks.
10
Never conclude about an untested variable. If light was not changed in the experiment, you cannot say anything about light's effect.

第四阶段 / 共5阶段 — 命题作文范文
命题作文范文：《一次难忘的帮助》（带批注）
题目：《一次难忘的帮助》 · 约200字 · 适合P6水平
那天，天空阴沉沉的，仿佛随时都会下起雨来。我背着沉重的书包，匆匆走向公共汽车站。
开头：以环境描写烘托气氛，营造紧张感，为事件发展作铺垫。
就在这时，我看见一位老奶奶费力地拖着一大袋东西，步履蹒跚地走着。袋子里装满了蔬菜，看起来十分沉重。她每走一步，都微微地弯着腰，额头上渗出了汗珠。
铺垫：通过细节描写（"步履蹒跚"、"渗出了汗珠"）具体呈现老人的困难处境，不是简单地说"她很辛苦"。
我犹豫了一下——万一她不需要帮助，岂不是令她难为情？可是，当我再次看到她那吃力的样子，心里一横，快步走上前去。"奶奶，我帮您提吧！"我说。她先是一愣，随即绽放出一个温暖的笑容："谢谢你，小朋友，真是个好孩子。"
高潮：写出内心的矛盾与挣扎，增加真实感。对话简洁自然，情感真挚。
我把老奶奶一路送到了家门口。道别时，她握着我的手说："现在像你这样热心的孩子不多了。"
结局：言简意赅，不拖沓，用老人的话推进故事走向收尾。
回家的路上，我的脚步轻快了许多。那一刻，我明白了：帮助别人，其实也是在温暖自己。
结尾：点明主题，以感悟升华。最后一句简洁有力，令人印象深刻。
常见失误： 结尾只写"我觉得帮助别人很重要"——太笼统，无法打动人。优秀的结尾要结合具体经历，写出发自内心的感受，才能让阅卷老师留下印象。
第五阶段 / 共5阶段 — 看图作文 + 常见失误
看图作文技巧 + 10个常见失误
看图作文要求根据图画内容写一篇记叙文 。图画是"提示"而非"剧本"——不要只描述图中看到的东西，而要以图画为起点，发挥想象力，补充细节，创造完整的故事 。
看图作文四步法
1
观察图画 ：图中有哪些人物？地点在哪里？正在发生什么事？图画传达出什么氛围？
2
想象补充 ：事情发生之前是怎样的？图画没有画出的细节是什么？人物在想什么、说什么？
3
确定主题 ：这个故事想表达什么？（如：互相帮助、坚持不懈、诚实守信等）
4
按结构写作 ：开头（设景/引入）→ 铺垫 → 高潮（图画所呈现的核心事件）→ 结局 → 感悟结尾。
10个常见失误——避免失分
1
开头用"那是一个……的早晨/下午"。 → 改用动作、对话或景物描写直接开篇。
2
全篇只有叙述，没有描写。 → 加入动作、语言、心理、环境描写，使内容具体。
3
结尾只写"这件事让我学到了……"。 → 要结合具体情节写感悟，不能空洞。
4
文中大量重复使用"然后……然后……然后"。 → 用"接着""随即""不一会儿""这时"等替换。
5
人物心理描写完全缺失。 → 适当加入"心里一紧""忐忑不安""如释重负"等心理感受。
6
标点使用错误（如用"，"代替"。"）。 → 一个意思完整的句子必须用句号结尾。
7
字迹潦草，涂改过多。 → 先打草稿再誊写，誊写时放慢速度，保持书写工整。
8
看图作文只描述图画，没有展开故事。 → 图画是起点，要在此基础上想象发挥，补充前因后果。
9
通篇使用简单短句，缺乏变化。 → 长短句交替使用，增强文章节奏感与可读性。

语文应用考查三大汉字能力：
字形辨析
形近字——字形相似但意思不同，如"己/已/巳"、"戊/戌/戍"。选出正确的汉字填入句子。
字音辨析
音近字和多音字——读音相同或相近但字义不同，如"做/作"；一字多音，如"调"(diào/tiáo)。
拼音应用
根据拼音选出正确汉字，或给汉字标注正确声调。考查声母、韵母、四声的掌握。
第一组 — 形近字辨析（字形）
第1题 字形 己/已/巳
选出填入句中空格最恰当的汉字：
A 己（zì jǐ — 自己）
B 已（yǐ jīng — 已经）
C 巳（sì — 天干地支之一）
答案：A — 己（zì jǐ）。 "自己 "意为本身、自身，此处填"己"组成"自己"。已 "（yǐ）表示已经（如已完成、已知）；"巳 "（sì）是天干地支中的字（如巳时），不用于"自己"。三字字形相近，须结合词义辨别。
第2题 字形 再/在
选出填入句中空格最恰当的汉字：
A 再……再……
B 在……再……
C 在……在……
D 再……在……
答案：B — 在……再…… 在 ：表示位置（放在 桌上）；再 ：表示再次、又一次（再 次检查）。这是PSLE最常考的形近字组合之一。
第3题 字形 做/作
下列句子中，哪一句中的加线汉字使用正确？
A 他每天早上都要作 早操。
B 他每天早上都要做 早操。
C 她是一位著名的做 家，出版了许多优秀的故事书。
D 同学们，请认真作 题，不要粗心大意。
答案：B。 做 早操 ✓ — 早操是具体的肢体动作，用"做"正确。作 早操"错误，应为"做早操"（具体动作用"做"）。做 家"错误，应为"作家"（书面专用称谓用"作"）。作 题"错误，应为"做题"（具体动作用"做"）。做 ＝具体动作（做饭、做作业、做早操）；作 ＝书面语/固定搭配（作家、作文、作品、作者）。
第二组 — 多音字辨析（字音）
第4题 多音字 调 diào/tiáo
根据句子意思，"调"字应读哪个音？调 换了一下。
A diào（调换、调动）
B tiáo（调节、调味）
答案：A — diào。 diào "的用法（调动、调换、调查）。tiáo "用于协调、调整的含义（调节温度、调味、调解矛盾）。记忆口诀：diào=移动/转变；tiáo=协调/平衡。
第5题 多音字 长 cháng/zhǎng
下列句子中，"长"字读音与其余三项不同的是哪一项？
A 这条河有多长？（cháng）
B 他的头发很长。（cháng）
C 小树慢慢地长大了。（zhǎng）
D 这根绳子不够长。（cháng）
答案：C。 长 大"的"长"读 zhǎng ，表示生长、增长。cháng ，表示长度。其他常见"zhǎng"用法：长大、成长、生长、族长、家长（长辈）。
第6题 多音字 好 hǎo/hào
选出"好"字读音正确的选项：好 学，常常废寝忘食地看书。
答案：B — hào。 好 学"意思是爱好学习、热爱学习，读 hào （hào xué）。hǎo "用于形容词（好人、好天气）；"hào "用于动词，表示"喜好/爱好"（好奇、爱好、好动）。"废寝忘食"作为后文的呼应也证明这是积极热爱学习的意思。
第三组 — 汉语拼音辨析
第7题 拼音 声调辨别
下列词语中，哪一组拼音完全正确？
A 精神 — jīng shén（均读第一声）
B 图书馆 — tú shū guán（"馆"读第二声 guán）
C 努力 — nǔ lì（第三声 + 第四声）
D 高兴 — gāo xīng（第一声 + 第一声）
答案：C — 努力 nǔ lì ✓。 二 声），不是第一声，故A错。三 声），不是第二声 guán，故B错。四 声），不是第一声 xīng，故D错。
第8题 拼音 根据拼音选字
根据拼音，选出正确的汉字：
答案：B — 精彩。
第四组 — 综合辨字（字形 + 字义结合）
第9题 字形+字义 常见错别字
下列四个词语中，哪一个含有错别字？
答案：C — 应为"再接再厉 "，而非"再接再励"。 厉 （lì），意为继续努力，再加一把劲。"厉"是严厉、磨砺之意；"励"是鼓励，两字字形相近但意思不同。这是PSLE常见错别字考点。
第10题 字形+字义 形近字选填
选出填入句中空格最恰当的汉字：
答案：C — 色彩……和谐。 色彩 （sè cǎi）：颜色与色调，"彩"有颜色、光彩之意。"色采"是错误写法（A、B均错）。和谐 （hé xié）："谐"含有协调融洽之意，是固定搭配。"和协"（A、D）是错别字组合，"协"虽有协调之意，但不与"和"搭配成词。
第11题 字形辨析 偏旁识别
下列哪组汉字，都含有"氵"（三点水）偏旁？
A 活、清、海、深、波、请
B 活、清、海、深、波、泳、洗、湖、江
C 活、清、海、深、波、浓、漂、请
D 活、清、海、深、波、激、洁、情
答案：B — 全部含有"氵"偏旁。
第12题 综合 字义辨析
下列哪个句子中，加线字的用法正确？
A 他返 复练习，终于学会了骑自行车。
B 这道题我看了很久，终于解 开了答案。
C 她渡 过了重重困难，终于成功了。
D 他反 复练习，终于学会了骑自行车。
答案：D — "反 复"用"反"正确。 反复 （fǎn fù）：一遍又一遍，"反"是正确用字 ✓返 复"错误——"返"表示回返（返回家乡、返回），不用于"反复"这一固定搭配。解 开答案"搭配不当——应为"找到答案"或"解开谜题"，"解开"与"答案"不搭配。渡 过困难"错误——"渡"多用于穿越水域（渡河、渡船）；克服/经历困难应用"度过"（度过难关）。
下一专题：词语运用 ↗
下一专题：句子结构 ↗
词语运用考查三类题型：
近义词辨析
意思相近但用法不同，如"爱护/保护"、"改善/改变"。须结合句子语境选出最恰当的词。
成语运用
选出适合语境的成语，或判断成语用法是否正确。须理解成语的本义和比喻义，避免望文生义。
习用语/量词/补语
固定搭配（如"一模一样"）、量词选用（一匹马/一头牛/一只鸟）、结果补语（听清楚/说明白）。
第一组 — 近义词辨析
第1题 近义词 爱护 / 保护 / 维护
选出填入句中空格最恰当的词语：
答案：A — 爱护。 爱护 ：爱惜并保护，含有珍视与关爱的感情色彩，多用于公共财物、环境、弱小的人或物（爱护公物、爱护小动物）。保护 ：使不受侵害，侧重防护作用（保护环境、保护眼睛）。维护 ：使不受损害，多用于权益、秩序（维护权益、维护和平）。语境中"不要随意破坏"对应"珍惜爱惜"的态度，"爱护"最贴切。
第2题 近义词 改善 / 改变 / 改正
选出填入句中空格最恰当的词语：
答案：A — 改善。 改善 ：使状况变得更好，有"从差到好"的方向（改善环境、改善生活条件）。改变 ：使不同于原来，不含好坏判断（改变方向、改变想法）——语义太中性。改正 ：改掉错误，对象通常是错误、缺点（改正错误、改正坏习惯）——不适合"环境"。
第3题 近义词 遵守 / 遵照 / 服从
选出填入句中空格最恰当的词语：
答案：A — 遵守。 遵守 ：遵照并严格执行（遵守规则、遵守纪律）——固定搭配是"遵守+规定/纪律/法律/规则"。遵照 ：按照某人的指示去做（遵照指示、遵照吩咐）——搭配的对象多为"指示""嘱咐"，而非"规则"。服从 ：听从命令（服从命令、服从安排）——含有被动接受的意味，"自觉服从规则"语感不够自然。
第二组 — 成语运用
本组成语参考：
废寝忘食 形容极其专注，连睡觉和吃饭都顾不上
马到成功 比喻事情一开始就获得成功（祝愿语）
半途而废 做事做到一半就放弃了（贬义）

C 一匹马、一头猪、一只鸟、一条鱼、一棵树、一张椅子
D 一头马、一头猪、一只鸟、一条鱼、一棵树、一张椅子
答案：C。 匹 （D中"一头马"错误）头 （B中"一只猪"错误；猪、牛、羊等大型牲畜用"头"）只 （A中"一条鸟"错误；禽类、小动物用"只"）条 （正确）棵 （B中"一株树"——"株"为书面语，日常规范用"棵"）张 （规范搭配；桌、椅、床等家具用"张"）
第8题 量词 文章/书/信
选出填入句中空格最恰当的量词：
答案：C — 篇……篇。 篇 （一篇日记；"则"用于新闻/笑话/短消息，如"一则新闻"，不用于日记）篇 （固定搭配：一篇文章、一篇报道）
第四组 — 习用语与固定搭配
第9题 习用语
选出填入句中空格最恰当的词语：
答案：A — 辛勤。 辛勤苦干 "是固定搭配成语，意为勤劳努力地工作，"辛勤"与"苦干"相辅相成，是规范用法。辛苦 "（B）虽有辛劳之意，但"辛苦苦干"语义重叠，不是惯用搭配（两个词都含"苦"字，重复冗余）。辛酸 "指心酸悲苦，强调情绪感受，而非劳动状态；"辛辣 "指味道刺激，与语境完全无关。
第10题 固定搭配 动宾搭配
下列哪个句子中，动词与宾语的搭配最为恰当？
A 我们要发扬良好的学习习惯。
B 他的演讲充分体现了勇气和智慧的发挥。
C 我们要养成良好的学习习惯。
D 这次活动加强了同学们的团队精神。
答案：C。 养成 习惯"是固定搭配；A中"发扬习惯"错误（"发扬"搭配"精神/传统/优点"）；B中"发挥的发挥"语义重复，句子结构不自然；D中"加强团队精神"——通常说"增强团队精神"或"培养团队精神"，"加强"多搭配"合作/管理/纪律"。
第五组 — 综合词语辨析
第11题 综合 程度词辨析
选出填入句中空格最恰当的词语：
答案：C — 详细。

阅读短文 — 《一棵树的坚持》
【第一段】 在学校操场的角落里，有一棵老榕树。它不像其他地方的榕树那样枝繁叶茂、气派非凡，它的主干歪歪扭扭，有几根粗壮的树根甚至裸露在地面上，像是一双粗糙的手，紧紧抓住土地。每当刮风下雨，别的树摇来晃去，它却始终稳稳地立在那里，好像什么都奈何不了它。
【第二段】 校工老伯告诉我，这棵榕树已经在这里生长了将近七十年。那时候，这里还是一片荒地。有人把一颗小小的榕树种子随手丢进了泥土里，也没有人去管它。谁知道，它竟然在那片贫瘠的土地上发了芽、生了根，一年一年地长大，熬过了一个又一个酷热的夏天和干旱的秋天。
【第三段】 树下有几块石头，是同学们常常坐着聊天休息的地方。有人说，坐在榕树下面，心里特别踏实。一位同学告诉我，他有一次在考试前非常紧张，一个人跑到树下坐了一会儿，看着那些盘根错节的树根，不知为何，心里慢慢平静下来。
【第四段】 去年，学校曾经讨论过要把这棵树移走，因为它裸露的树根影响了操场的整洁。后来，许多老师和同学联名写信，希望保留这棵树。信里有一句话让我印象最深刻："一棵经历了七十年风雨的树，它的根已经深深嵌入这片土地，也嵌入了我们每一个人的记忆。"最终，学校决定保留这棵树，并在周围铺上了防滑地砖。
【第五段】 每次经过那棵老榕树，我都会停下来看一看。它不需要人的照料，不需要人的赞美，只是默默地生长，用它的存在，告诉每一个走过的人：只要扎根够深，什么样的风雨都能扛过去。
作答以下各题（每题2分）
第1题 字面理解
根据第二段，这棵榕树是怎样在校园里生长起来的？
A 学校特地找人把榕树种在操场角落，并细心照料。
B 校工老伯在七十年前亲手把种子种在学校里。
C 有人随意把种子丢入土里，无人照顾，它自己发芽生长。
D 这棵树是从别处移植过来的，移来时已经很大了。
答案：C。 文章第二段明确写道："有人把一颗小小的榕树种子随手丢进了泥土里，也没有人去管它。谁知道，它竟然……发了芽、生了根。"答案直接来自文章，须注意"随手丢""也没有人去管"这两个关键细节。A、B和D均不符合原文。
字面理解题的答题提示： 先找到题目所指的段落，再在段落中找出相关句子，用自己的话核对选项。不要凭印象选择，要回到原文确认。
第2题 推断理解
第三段提到同学坐在榕树下"心里慢慢平静下来"。这说明了什么？
A 榕树能发出一种特殊的气味，帮助人平静情绪。
B 坐在树下比待在教室里更舒服，所以容易放松。
C 这棵历经风雨仍然稳立的老树，给人一种沉稳、踏实的力量。
D 同学在树下遇到了朋友，和朋友聊天后才平静下来。
答案：C。 这道题要"读字面以外的意思"。第三段写同学"看着那些盘根错节的树根……心里慢慢平静"——树根象征着深扎土地、稳固不移的力量。结合全文对老榕树坚韧不拔形象的描写，可以推断：树的稳定感给人心理上的支撑与安慰。A文中未提及；B和D均是无中生有的推断。
第3题 推断理解
第四段中，联名信里写道："它的根……也嵌入了我们每一个人的记忆。"这句话的意思是什么？
A 榕树的树根非常长，已经蔓延到每个人居住的地方。
B 这棵榕树已经成为大家生活与情感的一部分，难以忘怀。
C 每个人都记得这棵树的具体位置和样子。
D 这棵树的年龄太长了，所有人都知道它的历史。
答案：B。 "根嵌入记忆"是比喻的写法——"根"在这里不是指真实的树根，而是比喻这棵树在人们心中留下的深刻印记，已经成为大家情感与生活不可分割的一部分。这是PSLE最常考的推断题类型：理解文中比喻或含蓄表达的真正含义。A是字面误读；C和D过于表面，未理解比喻含义。
第4题 归纳评价
根据全文，下列哪项最能概括这篇文章的主旨？
A 介绍学校操场角落里一棵老榕树的外貌和历史。
B 说明学校为了保留榕树而作出的努力与决定。
C 借老榕树历经风雨仍坚韧生长，表达只要扎根够深便能承受困难的道理。
D 批评学校曾经想要移走榕树的做法，呼吁大家保护自然。
答案：C。 主旨题要看
全文的核心信息 ，尤其是开头和结尾。文章结尾明确点出："只要扎根够深，什么样的风雨都能扛过去。"这是文章的中心思想——以榕树为喻，表达坚韧、扎根的精神。A和B只是文章的部分内容，不是主旨；D文中从未有"批评"的语气，属于过度解读。
归纳主旨题的答题方法： 先看文章结尾（作者往往在结尾点明主旨），再看题目（文章名称有时也是提示），最后排除只描述局部内容的选项。
第5题 归纳评价
根据文章，老榕树的哪些特点令人印象深刻？以下哪项概括最全面、最准确？
A 外形高大美丽，是校园里最壮观的一棵树。
B 历史悠久，树根很深，同学们喜欢在树下玩耍。
C 无需人照料，自然生长，对学校环境造成了一些影响。
D 外形虽不出众，却历经七十年风雨顽强生长，给人以沉稳踏实的力量，已成为师生共同记忆的一部分。
答案：D。 D是最全面的概括，包含了文章的四个核心层面：（1）外形普通但坚韧（第一段）；（2）历经七十年风雨自力生长（第二段）；（3）给人沉稳的力量（第三段）；（4）已成为师生共同的情感记忆（第四段）。
A与文章第一段矛盾（文章明确说它"不像其他榕树那样枝繁叶茂、气派非凡"）；B过于简单，遗漏了情感意义；C虽提到"对环境的影响"，但这只是文章的一个小细节，不能代表全文。
概括题的答题策略： 概括题的正确答案往往覆盖文章的多个层次 ，而错误选项通常只涉及其中一个细节，或与原文有直接矛盾。逐项对照文章内容，排除与原文不符的选项。

小华请小文解释第三段的比喻，小文应如何回应？
A 没问题，我可以试着跟你解释一下。
B 那个比喻我也不明白，你去问老师吧。
C 你每次都要问我，自己要多用功一点。
D 那段我没有看，不知道。
答案：A — "没问题，我可以试着跟你解释一下。"
第4题（空格4）礼貌回应
小华问今天有没有体育课，小文应如何回应？
A 有体育课，你快去换衣服。
B 忘记带鞋的话就不要上体育课了。
C 你怎么这么粗心，每次都忘东忘西的。
D 这个我也不太清楚，课表好像有改过。
答案：D — "这个我也不太清楚，课表好像有改过。" 不确定 答案，所以才建议去问老师。D表达了不确定（"不太清楚"），与后文建议问老师的逻辑完全吻合。A肯定"有体育课"，与"赶快去问老师"矛盾（若已知，就不必再问）；B和C语气均不合适，B是消极建议，C带批评语气。

开放式问答
答案须用
自己的话 回答，不能整句照搬原文。分值较高的题目须答出多个要点。先找到原文依据，再用流畅的语言表达。
书面互动
以书信/短信/电邮形式回复，须包含正确的
格式 （称谓、正文、署名）、
内容要点 （不能遗漏）和
适当语气 （礼貌或亲切，视对象而定）。
分值分配
阅读理解二共32分，是试卷二中分值最高的部分。每个开放式问题通常2–4分，书面互动约5–8分。
审题技巧
注意题目中的"根据文章"——答案必须来自文章，不能凭空想象。"用自己的话"——须改写原文，不能直接抄。
阅读短文 — 《志愿者的一天》
【第一段】 那是一个星期六的早晨，我第一次以志愿者的身份走进了养老院。推开大门的那一刻，我有些迟疑——我不知道该说什么，也不知道该做什么。队长林叔叔看出了我的紧张，拍了拍我的肩膀，笑着说："放轻松，他们最需要的，只是有人陪。"
【第二段】 我被分配去陪伴一位叫郑奶奶的老人。她坐在窗边，安静地看着窗外的小花园，手里捏着一串佛珠。我不知从何开口，便随口问了一句："奶奶，您喜欢花吗？"她转过头来，眼睛顿时亮了起来，话匣子就这样打开了——她告诉我，她年轻时在老家种过很多花，最喜欢白色的茉莉花，因为那个味道会让她想起她的母亲。
【第三段】 我们聊了将近一个小时。郑奶奶说，她的儿女都在工作，很少来探望，平时的日子"安静得让人发慌"。她说这句话的时候，并没有抱怨的意味，语气里只有一种淡淡的寂寞。我忽然意识到，对这些老人来说，"安静"不一定是舒适，有时候也是一种孤独。
【第四段】 临走前，郑奶奶握住了我的手，说："你下次还会来吗？"我点了点头，说一定会来。走出养老院，我回头望了一眼——她还站在窗口，朝我挥手。那一刻，我的心里有一种难以描述的感受：不是悲伤，却比悲伤更难受；不是快乐，却比快乐更有意义。
【第五段】 这一天的经历让我明白了一件事：做志愿工作，不只是完成一项任务，更是用真心去感受另一个人的生命。我们给的，也许只是一个下午；他们得到的，却可能是一整周的温暖。
第一部分 — 开放式问答（共9分）
第1题 字面理解 2分
根据第二段，郑奶奶为什么特别喜欢茉莉花？
显示参考答案
因为茉莉花的香味会让她想起她的母亲，茉莉花承载着她对母亲的思念与回忆。
得分要点： （1）茉莉花的味道/香味让她想起母亲——1分；（2）表达出情感连结（思念/回忆/感情）——1分。只回答"她喜欢茉莉花"而不解释原因得0分。
常见失误： 直接抄原文"那个味道会让她想起她的母亲"——须改用自己的话，否则可能被扣分。
第2题 推断理解 3分
第三段中，郑奶奶说日子"安静得让人发慌"。这句话反映了她怎样的生活处境和内心感受？请结合文章内容回答。
显示参考答案
这句话反映了郑奶奶独居养老院、缺乏陪伴的孤独处境。她的儿女工作繁忙，很少来探望，所以她每天都是一个人，生活中缺乏热闹与交流。"安静得让人发慌"说明这种安静并非她主动选择的宁静，而是一种令她感到不安、甚至恐惧的孤独感。作者也因此意识到，对老人来说，"安静"有时意味着寂寞。
得分要点（共3分）：
区分字面与推断： 只回答"她儿女很少来"得1分（字面）。要拿满分，须推断出她的心理状态，并理解"安静"在这里的特殊含义。
第3题 归纳评价 4分
第四段描述作者临走时的感受："不是悲伤，却比悲伤更难受；不是快乐，却比快乐更有意义。"请解释这句话的含义，并说明作者为什么会有这样的感受。
显示参考答案
这句话表达了作者内心复杂而深刻的情绪。"比悲伤更难受"是因为看到郑奶奶仍然站在窗口挥手，作者感受到了老人内心深处的孤独与期待，这种感受让他心里沉甸甸的，比单纯的悲伤更触动人心。"比快乐更有意义"是因为这次陪伴虽然简短，却给了老人真实的温暖，让作者体会到帮助他人的价值与意义，远不只是表面上的高兴。总体而言，这句话说明作者通过这次志愿服务，对生命和人与人之间的情感有了更深刻的感悟。
得分要点（共4分）：

第一阶段 / 共5阶段 — 考试概况
口试结构与评分说明
口试共50分 ，占总分25% ，分两个部分，考前有10分钟准备时间 ——默读篇章，同时反复观看一段录像短片。
第一部分：朗读篇章（20分 / 10%）
朗读一篇短文（约150字）。评分标准：发音是否准确、吐字是否清晰、语调是否自然、语速是否适当、是否有感情地朗读。
第二部分：会话（30分 / 15%）
主考员根据录像短片内容与考生对话。评分标准：回答是否切题、内容是否充实、语言是否流畅准确、能否主动表达观点与感受。
会话（30分）是分值最高的单一项目 ，比朗读多出10分。许多同学把大部分准备时间花在朗读上，忽略了会话练习，这是最常见的备考误区。
第二阶段 / 共5阶段 — 朗读技巧
朗读篇章——五个提升技巧
朗读不是"把字念出来"，而是"用声音传达文章的情感"。准备时间里，把篇章默读两遍，找出情感转折点，再轻声练习一遍。
练习用篇章（请大声朗读）
那天放学后，天色已经暗了下来。我一个人走在回家的路上，脑子里还转着今天考试的题目。忽然，我看见路边一位老爷爷正蹲在地上，费力地捡散落一地的水果。我犹豫了一下，还是走了过去，帮他把水果一个个捡起来放回袋子里。老爷爷抬起头，对我微微笑了笑，说了一声"谢谢"。那笑容很简单，却让我走完剩下那段路时，脚步轻了许多。
五个朗读技巧
1
在标点符号处停顿。 逗号=短停（约半秒）；句号=长停（约一秒）；破折号/省略号=拉长停顿，增加感情色彩。不停顿会让句子听起来像在赶路。
2
重读关键词，轻读过渡词。 如"费力 地捡"、"犹豫 了一下"——动词和形容词要稍微加重，助词、连词轻带过去。
3
语速有快有慢。 描述动作时可稍快；描写心情、感悟时要放慢，体现思考感。上面篇章中"那笑容很简单，却让我……"要放慢，读出回味的感觉。
4
抬眼看主考员。 不要全程低头盯着纸。读完一句后，自然地抬眼扫一眼主考员，传达"我在和您交流"的感觉，而不是在背稿。
5
声母韵母要发准。 常见错误：n/l不分（"牛"念成"刘"）、前后鼻音混淆（"人"ren vs"仁"rén）、翘舌音（zh/ch/sh）发不到位。准备时把不确定的字先查好。
常见失误 全程用同一个音调平读，没有停顿、没有起伏、没有感情——即使发音准确，也会在"语调自然"一项中失分。
第三阶段 / 共5阶段 — 会话策略
录像短片会话——答题的三层结构
主考员会根据录像短片提问，话题通常与日常生活、社区、环境、家庭、成长等主题相关。问题分三个层次——先问"你看到了什么"，再问"你觉得为什么"，最后问"你有什么看法或经历"。
三层答题结构
1
第一层：观察（描述短片内容）
2
第二层：分析（解释原因或影响）
3
第三层：联系（结合自身经历或看法）
提升会话分数的习惯
多说，不要单句答
主考员问一句，你至少答三到四句。每个观点后加上"因为……"或"举例来说……"展开。
用四字词语
会话中用一两个四字词语（如"助人为乐"、"废寝忘食"）会明显提升语言印象。
表达看法时用句式
"我认为……因为……"、"依我看来……"、"从我的角度来说……"——不要只说"我觉得好"。
听不懂可以请求重复
主考员说的话没听清楚，可以说"对不起，请您再说一遍，好吗？"这是正常的，不会扣分。
第四阶段 / 共5阶段 — 模拟会话示范
模拟录像话题 + 示范对话（带批注）
录像短片：社区义工活动
青少年与老人一起种植蔬菜
短片描述：画面中，几位中学生和养老院的老人们在社区菜园里一起种植蔬菜。青少年帮助老人翻土、浇水，双方有说有笑，气氛融洽。
主考员：你在短片里看到了什么？
不足 我看到一些学生和老人在种菜。
短片里，我看到几位青少年和养老院的老人们在一个社区菜园里共同劳动。青少年们在帮老人翻土和浇水，大家有说有笑，气氛非常融洽。看得出来，这是一个代际交流的义工活动。
✓ 有具体细节（翻土、浇水）；✓ 有场景描述（社区菜园）；✓ 有观察分析（"代际交流"）——比只说"种菜"丰富得多。
主考员：你觉得青少年参与这类义工活动有什么好处？
不足 可以帮助老人，也可以学到很多东西。
我认为好处有很多。首先，青少年通过陪伴老人，可以学会体谅他人、关心社会，培养助人为乐的精神。其次，与老人交流可以让我们了解他们丰富的人生经验和智慧，这是课本上学不到的。此外，这类活动也让老人感受到被重视和关怀，减少他们的孤独感，对他们的身心健康很有帮助。
✓ 三个层次的好处（青少年品德、学习、老人得益）；✓ 使用"助人为乐"四字词语；✓ 逻辑清晰，用"首先…其次…此外"串连。
主考员：你有没有参加过类似的义工活动？有什么感受？
我曾经参加过学校组织的探访活动，去过一间养老院陪老人聊天。起初我有点紧张，不知道该说什么。后来，我问了一位奶奶她年轻时的故事，她一下子就打开了话匣子，跟我聊了很久。那次经历让我体会到，有时候，我们给出的只是一个下午，对方却能感受到整整一周的温暖。所以我觉得，义工工作不只是帮助别人，更是让自己成长的机会。
✓ 有具体经历（不只说"参加过"）；✓ 有心理变化（紧张→打开话匣子）；✓ 有感悟升华（"给出一个下午，对方感受一周温暖"）——这是区分普通答案与高分答案的关键。
第五阶段 / 共5阶段 — 常见话题与10个应试习惯
录像短片常见话题 + 10个提分习惯
常见录像话题与应对词汇
环境保护

社区与义工
助人为乐/服务社区/代际交流/互相关爱/奉献精神/感恩回馈

科技与生活
善用科技/网络礼仪/不沉迷游戏/平衡线上线下生活/批判性思维
健康生活
均衡饮食/规律作息/积极运动/保持健康体魄/心理健康同样重要
10个口试应试习惯
1
准备时间优先观看录像。 篇章可以边朗读边熟悉，但录像只能在准备时看——把握短片的主题、人物和关键情节，是会话成功的基础。
2
朗读时不要太快。 紧张时语速容易加快，导致发音不清晰。刻意放慢，留时间停顿，反而听起来更从容自信。
3
会话答案要有"因为"。 每个观点后都补上原因，如"我认为……因为……"，这是拿到第二分的关键。
4
联系自身经历时要具体。 不要说"我也有过类似的经历"——要说出是什么经历、发生了什么、你有什么感受。
5
每个回答至少说三句话。 一句话的答案不能给主考员留下好印象，也无法展示你的语言能力。
6
会话时保持眼神接触。 自然地与主考员对视，不要低头或望向旁边，传达出你在认真交流而非背稿。
7
不要死记硬背模板答案。 主考员会根据你的回答追问，死记的答案很容易崩溃。多练习思路，而不是背固定句子。
8
适当使用"感悟升华"句式。 如"这让我明白了……"、"这次经历让我体会到……"——结尾一句有深度的感悟，能大幅提升会话的整体印象。
9
说错了不要慌，可以自我纠正。 "不对，我想说的是……"——主考员不会因为一两处语病就大幅扣分，流畅与内容比完美更重要。
10
日常多用华语交谈。 口试考的是自然流畅的语言运用能力，临时抱佛脚效果有限。每天和家人或同学用华语说几分钟，是最有效的长期备考方式。

录音材料一 — 对话（第1–2题）
【模拟听力：请先阅读第1、2题题目，再阅读以下对话内容，然后作答。】
妈妈： 小杰，你今天放学怎么这么晚才回家？已经六点半了。
小杰： 妈，对不起。我留下来帮老师把图书馆的书重新整理了一下，忘了时间。
妈妈： 哦，原来是这样。不过下次留下来帮忙，要先通知我一声，知道吗？我等了你很久，担心死了。
小杰： 知道了，妈，对不起，我下次一定提前告诉你。对了，老师说我整理得很认真，还夸我了呢。
妈妈： 做好事当然好，不过也要让家人知道你在哪里，这样大家才不会担心。来，快去洗手，饭菜都凉了。
第1题 对话 字面理解
小杰为什么回家晚了？
A 他在学校参加了课外活动。
B 他留下来帮老师整理图书馆的书。
C 他和同学在外面玩，忘了回家。
D 他迷路了，找不到回家的路。
答案：B。 小杰说"我留下来帮老师把图书馆的书重新整理了一下，忘了时间"。这道题是直接信息题，答案在对话中明确说出。
听力技巧：问"为什么"的题目，答案通常是说话人解释的那句话。注意听"因为"、"是因为"或解释性的内容。
第2题 对话 推断态度
妈妈对小杰帮老师整理图书馆这件事，态度是怎样的？
A 完全反对，认为应该立刻回家。
B 非常生气，批评小杰不懂事。
C 认同做好事，但要求下次先通知家人。
D 完全不在意，只关心饭菜凉了。
答案：C。 妈妈说"做好事当然好，不过也要让家人知道"——"当然好"表示认可，"不过"表示转折提出要求。这是态度题，须综合判断，不能只抓一句话。
听力技巧：态度题须听完整段话，尤其注意转折词"不过""但是""只是"——转折后的内容往往才是说话人的真正态度。
录音材料二 — 通告（第3–4题）
【模拟听力：请先阅读第3、4题题目，再阅读以下通告内容，然后作答。】
全体同学请注意。本校图书馆将于本周五（即本月二十日）下午两点至五点进行书架重新安排，届时图书馆将暂停开放。如需借还书籍，请在本周四下午五点前完成。另外，图书馆订购的一批新书将于下周一上架，届时欢迎同学前来借阅。有意了解新书书目的同学，可于明天早上到图书馆柜台索取书单。谢谢各位同学的合作。
第3题 通告 细节信息
同学们最迟在什么时候必须完成借还书籍？
A 本周五下午两点前。
B 本周四下午五点前。
C 本月二十日下午五点前。
D 下周一上午。
答案：B。 通告明确说"如需借还书籍，请在本周四下午五点前完成"。A是图书馆暂停开放的时间（周五下午两点），不是借还书的截止时间。这道题考查在同一则通告中辨别不同时间点的能力。
听力技巧：通告中通常有多个时间点，须仔细区分每个时间对应的事件。建议在题目旁边标注关键时间，避免混淆。
第4题 通告 细节推断
想提前了解新书书目的同学，应该怎么做？
A 等到下周一新书上架后，到图书馆翻阅。
B 在本周五图书馆关闭前向柜台查询。
C 明天早上到图书馆柜台索取书单。
D 发电邮给图书馆老师查询新书书目。
答案：C。 通告最后说"有意了解新书书目的同学，可于明天早上到图书馆柜台索取书单"。D（发电邮）是通告中没有提到的方法，属于无中生有。
录音材料三 — 说明介绍（第5–6题）
【模拟听力：请先阅读第5、6题题目，再阅读以下内容，然后作答。】
同学们，今天我来向大家介绍一种新加坡特有的树木——雨树。雨树因为叶子在下雨前会自动合拢、遮蔽下方的空间而得名。雨树的树冠非常宽大，一棵成年雨树的树荫可以覆盖将近一千平方米的范围，因此常常被种植在公园、路边和学校，为人们提供遮阴的地方。雨树的寿命很长，有些雨树已经生长超过一百年。值得注意的是，雨树虽然高大，但它的根系非常深，因此即使遇到强风，也很少被吹倒。希望大家下次在路边看到雨树时，能想起它的名字和特点。
第5题 说明介绍 字面理解
雨树的名字是怎么来的？
A 因为雨树只在雨天才会开花。
B 因为雨树的叶子在下雨前会自动合拢。
C 因为雨树的树荫下经常会积水。
D 因为雨树在雨季时生长得最旺盛。
答案：B。 录音说"叶子在下雨前会自动合拢、遮蔽下方的空间而得名"。这是直接信息题，关键词是"下雨前 "（不是下雨时），须听清楚时间词。
第6题 说明介绍 综合理解
根据录音，以下哪项关于雨树的描述是正确的？
A 雨树的树冠很小，适合在狭窄的地方种植。
B 雨树的寿命通常不超过五十年。
C 雨树的根系很浅，容易在强风中被吹倒。
D 雨树因根系深，即使遇强风也不容易倒塌。
答案：D。 录音说"它的根系非常深，因此即使遇到强风，也很少被吹倒"。A、B、C均与录音内容相反（树冠宽大、寿命超百年、根系深）。这类题目故意把原文中的描述反转成错误选项，须认真核对。
听力技巧：这类"哪项正确"的综合题，通常有多个选项直接把原文中的描述反转。每个选项都要回到录音中核对，不要凭印象选择。
录音材料四 — 故事叙述（第7–8题）
【模拟听力：请先阅读第7、8题题目，再阅读以下故事，然后作答。】
从前有一个农夫，他有两个儿子。大儿子勤劳肯干，每天早起耕田，但做事冲动，经常因为一时冲动而做出错误的决定。小儿子则头脑灵活，遇事会先思考，但他非常懒惰，什么事都不愿意去做。农夫年迈了，开始担心把农田留给谁。他召集两个儿子，给了他们同一块田地，让他们各自耕种半年。半年后，大儿子的田里丰收了，但他粗心地把种子放错了地方，损失了三分之一的收成。小儿子的田里杂草丛生，几乎颗粒无收，因为他总是想着"明天再做"。最后，农夫叹了口气说："勤劳而不冲动，聪明而不懒惰，这样的人才能把田种好。"
第7题 故事 人物比较
根据故事，大儿子和小儿子各自的主要缺点是什么？
A 大儿子懒惰；小儿子冲动。
B 大儿子不聪明；小儿子不勤劳。
C 大儿子冲动易犯错；小儿子聪明但懒惰。
D 大儿子和小儿子都懒惰，不愿意耕田。
答案：C。 故事明确说大儿子"做事冲动，经常因为一时冲动而做出错误的决定"；小儿子"头脑灵活……但他非常懒惰"。A把两人的缺点对调了——这是此类题目最常见的干扰选项设计。
第8题 故事 主旨寓意
这个故事的主要寓意是什么？
A 农田的收成取决于天气和运气。
B 勤劳的人一定比聪明的人更成功。
C 一个人既要勤劳，又要沉稳思考，才能做好事情。
D 年长的父亲总比年轻的儿子更有智慧。
答案：C。 故事结尾农夫直接说出寓意："勤劳而不冲动，聪明而不懒惰，这样的人才能把田种好。"这道题可以从故事结尾的总结句中直接找到答案。
听力技巧：故事型录音的主旨寓意通常在结尾点明。注意听最后一两句话，往往是关键。
录音材料五 — 广告（第9–10题）
【模拟听力：请先阅读第9、10题题目，再阅读以下广告内容，然后作答。】
想让孩子爱上阅读？"书香小屋"儿童阅读中心正式开业了！中心位于宏茂桥地铁站旁，提供超过三千册适合四岁至十二岁儿童阅读的中英双语图书。每周六及周日上午十时至下午四时开放，会员每月只需十五元，即可无限次借阅。此外，本月加入会员，还可免费参加每周五下午三时举行的故事讲述活动。首批会员名额有限，欲报名者请于本月底前致电六八七八零八零八，或亲临中心登记。
第9题 广告 细节信息
"书香小屋"儿童阅读中心在哪些时候开放？
A 每天上午十时至下午四时。
B 每周一至周五上午十时至下午四时。
C 每周六及周日上午十时至下午四时。
D 每周五至周日上午十时至下午四时。
答案：C。 广告说"每周六及周日上午十时至下午四时开放"。D（周五至周日）是错误的，因为故事讲述活动在周五，但阅读中心的开放时间只有周六和周日。注意区分"开放时间"与"活动时间"这两个不同信息。
第10题 广告 优惠条件
根据广告，什么条件下可以免费参加故事讲述活动？
A 所有到访者都可以免费参加。
B 本月内加入会员的人可以免费参加。
C 只要支付额外费用，任何时候都可以参加。
D 四岁至十二岁的儿童可以免费参加。
答案：B。 广告说"本月加入会员，还可免费参加每周五下午三时举行的故事讲述活动"——关键条件是"本月加入会员"，不是所有人都有资格。A和D是没有条件限制的错误说法。
听力技巧：广告中的优惠条件往往有时间限制（"本月"）或身份限制（"会员"），须注意听清楚条件词，不要只记住优惠内容而忘记条件。
