PSLE Synthesis & Transformation: The Rules, with Worked Examples
How to use this page: read each rule and its worked example, then attempt the MCQ to choose the correct transformation before checking the explanation. The wrong options are the classic traps.
Synthesis & Transformation (S&T) is the most rule-based part of Paper 2, which is good news. You're given a sentence and a word or two to rebuild it around, and you must keep the meaning exactly the same. Learn the handful of common patterns and this becomes one of the most reliable sections to score in.
The golden rule: the meaning must not change, and no information may be added or dropped. Most marks are lost not to grammar, but to a small change in meaning.

The common transformation types
1. although / even though / though
Joins two contrasting ideas using a full clause (subject + verb).
Given: It was raining heavily. We still went to the park. Although: Although it was raining heavily, we still went to the park.
Trap: after although, you need a clause, not just a noun. "Although the heavy rain" is wrong; it must be "although it was raining".
Combine using ALTHOUGH: 'He was very tired. He finished the race.' Which is correct?
Show answer & explanation
Answer: (B) Although he was very tired, he finished the race.
The correct answer is (B). 'Although' must be followed by a full clause (subject + verb): 'he was very tired'. (A) follows 'although' with a noun ('his tiredness'), which is the despite/in spite of pattern, not although. (C) adds 'but'; you never pair 'although' with 'but' in the same sentence. (D) is not a proper clause and turns the second idea into a noun phrase, dropping the verb.
2. despite / in spite of
Same meaning as "although", but followed by a noun or -ing, not a full clause.
Despite: Despite the heavy rain, we still went to the park.
Trap: never write "despite of". It's either despite or in spite of, never a mix of the two.
Rewrite using DESPITE: 'Although she was ill, she attended the concert.' Which is correct?
Show answer & explanation
Answer: (C) Despite her illness, she attended the concert.
The correct answer is (C). 'Despite' is followed by a noun or -ing form: 'her illness' (or 'being ill'). (A) is the classic 'despite of' trap: 'of' is never added after 'despite'. (B) and (D) both wrongly follow 'despite' with a full clause ('she was ill'), which is the although pattern. Remember: despite + noun/-ing; although + clause.
3. unless (= if… not)
Given: If you do not hurry, you will miss the bus. Unless: Unless you hurry, you will miss the bus.
Trap: unless already contains the "not", so don't write "unless you do not hurry", which reverses the meaning.
Rewrite using UNLESS: 'If you do not water the plant, it will die.' Which is correct?
Show answer & explanation
Answer: (B) Unless you water the plant, it will die.
The correct answer is (B). 'Unless' already means 'if… not', so it replaces the 'do not': 'Unless you water the plant, it will die.' (A) keeps 'do not' as well, giving a double negative that reverses the meaning. (C) wrongly negates the result ('will not die'), changing the meaning entirely. (D) swaps cause and effect, so it no longer says the same thing as the original.
4. so … that / such … that
Shows a cause strong enough to produce a result.
Given: The soup was very hot. He could not drink it. So: The soup was so hot that he could not drink it. Such: It was such hot soup that he could not drink it.
Trap: so goes before an adjective (so hot); such goes before a noun phrase (such hot soup).
Rewrite using SO: 'The bag was very heavy. Nobody could carry it.' Which is correct?
Show answer & explanation
Answer: (B) The bag was so heavy that nobody could carry it.
The correct answer is (B). 'So' comes before an adjective: 'so heavy that…'. (A) uses 'such' before an adjective alone ('such heavy'), but 'such' needs a noun phrase ('such a heavy bag'). (C) swaps in the 'too… to' pattern and drops 'that', changing the structure the question asked for. (D) misplaces 'so' before a noun phrase ('so a heavy bag'), which is ungrammatical; it should be 'such a heavy bag'.
5. Reported (indirect) speech
Move the tense back one step and change the pronouns and time words.
Given: "I finished my homework yesterday," said Sam. Reported: Sam said that he had finished his homework the day before.
Trap: remember all three shifts: tense (finished → had finished), pronoun (I → he), and time (yesterday → the day before).
Report this: ‘“I will call you tomorrow,” said Mrs Rao.’ Which is correct?
Show answer & explanation
Answer: (B) Mrs Rao said that she would call me the next day.
The correct answer is (B). All three shifts happen: tense (will → would), pronouns (I → she, you → me), and the time word (tomorrow → the next day). (A) makes none of the shifts. (C) keeps the present 'will' and the time word 'tomorrow' unchanged. (D) shifts the tense correctly but forgets the pronoun ('you' → 'me') and the time word ('tomorrow' → 'the next day').
6. too … to / enough to
Given: The box was very heavy. She could not lift it. Too: The box was too heavy for her to lift. Enough: The box was not light enough for her to lift.
Trap: with too… to there's no "not": "too heavy to lift" already means she couldn't.
Rewrite using TOO: 'The tea was very hot. The child could not sip it.' Which is correct?
Show answer & explanation
Answer: (B) The tea was too hot for the child to sip.
The correct answer is (B). 'Too… to' already carries the negative meaning: 'too hot… to sip' means the child could not sip it. (A) adds 'not', which reverses the meaning. (C) mixes 'too' with the 'so… that' structure: 'too' takes 'to', not 'that'. (D) is not a valid transformation ('too… enough' cannot be combined, and it drops the negative result).
7. Passive voice
The object of the action becomes the subject.
Given: A famous chef cooked the meal. Passive: The meal was cooked by a famous chef.
Trap: keep the tense the same (cooked → was cooked, not "is cooked").
Rewrite in the passive: 'The gardener planted the roses last week.' Which is correct?
Show answer & explanation
Answer: (B) The roses were planted by the gardener last week.
The correct answer is (B). The object ('the roses') becomes the subject, and the past tense is kept: 'planted' → 'were planted'. (A) shifts the tense to present ('are planted'), but the original is past ('last week'). (C) uses '-ing' ('were planting') instead of the past participle 'planted'. (D) reverses who did what: the roses did not plant the gardener, so the meaning changes.
The two-second check that saves marks
After you transform a sentence, read your version and the original side by side and ask: "Do these mean exactly the same thing?" If your version accidentally makes it stronger, weaker, or reversed (a common unless mistake), fix it. Meaning first, grammar second.
