Synthesis and Transformation: The Question Types, the Rules, and the Marks Children Lose
Synthesis and transformation asks you to rewrite one or two given sentences as a single new sentence that keeps exactly the same meaning. You are given a starting word or a printed frame, and you must work out which grammatical change that frame forces. The meaning may not shift, nothing may be left out, and nothing new may be added.
It is worth marks in every P5 and P6 English paper, and the marks are lost in a small, predictable set of places — almost always because a pupil changed the wording without changing the grammar the frame demanded.
What Is Synthesis and Transformation?
The name describes two jobs, and most children only notice the first.
Synthesis is the joining: two sentences become one. Transformation is the rebuilding: the grammar has to change so that the joined sentence still says the same thing. A pupil who joins two sentences neatly but leaves the verbs, pronouns and tenses as they were has done half the task, and half the task earns no mark.
That is the reason a child can produce a sentence that is perfectly grammatical English and still be marked wrong. The question does not ask for a good sentence. It asks for the same meaning, rebuilt to fit the given frame.
What Are the Types of Synthesis and Transformation Questions?
There are nine families a P5 or P6 pupil should recognise on sight. The first is the largest — in one P6 set, five of eighteen items were nominalisations.
# | Question type | What the frame makes you do |
1 | Nominalisation | Turn a verb or adverb pair into an adjective + noun pair, and move it to the front — died suddenly → sudden death |
2 | Non-finite opener | Start with Having + past participle, or Upon + gerund, keeping the same subject as the main clause |
3 | Active to passive | Rebuild around the object, including the progressive passive (were being chewed) |
4 | Inversion | Front a negative or a conditional — No sooner had … than …, Had he …, he would have … |
5 | Connector substitution | Replace a connector and preserve the meaning — sometimes by flipping the polarity |
6 | Double negation | Negate two subjects at once with Neither … nor, dropping the auxiliary that is no longer needed |
7 | Relative pronoun placement | Position who, whom or whose correctly — often by reversing the clause order |
8 | Perfect aspect for a span | Choose the present perfect when a period runs from the past into the present, cued by Since |
9 | Reported speech, both directions | Direct to reported and reported back to direct — and the change table only runs one way |
What Are the Synthesis and Transformation Rules?
Six rules cover most of the marks.
The meaning must survive exactly. If the rewritten sentence is true in slightly different circumstances from the original, it is wrong however elegant it reads.
Use every part of both given sentences. An answer that quietly drops the second sentence is the commonest wrong answer of all, and it is examined below.
The frame chooses the grammar, not you. The printed starting word is an instruction. Since forces a tense decision; unless forces a negation; a lead-in noun forces the passive.
A fronted opener must share its subject with the main clause. Having finished her homework, Mei went out is correct because Mei both finished and went. Change one subject and the sentence breaks.
Additional-information phrases do not change the number of the verb. as well as, together with, except and neither of all look plural and none of them is.
Although never appears with but, and the reason goes first. One connector does the whole job. When a sentence contrasts a reason with an outcome, the reason is what follows Although — putting the surprising part there inverts the emphasis and usually the meaning with it.
Synthesis and Transformation Examples: Five Worked Items With the Marked Answers
1. The connector that has to flip the meaning
Given: Norman will speak to you if you apologise to him. Frame: ______ unless ______
→ Norman will not speak to you unless you apologise to him.
unless already means if not, so the main clause has to become negative for the meaning to hold. A pupil who writes "Norman will speak to you unless you apologise" has said the opposite of the original. Both the connector and the main clause flip, or neither does.
2. The passive that keeps its aspect
Given: My pet dog was chewing my slippers. Frame: My slippers ______
→ My slippers were being chewed by my pet dog.
were chewed is the answer most children give, and it loses the mark because it loses the aspect: the original describes chewing in progress. The given sentence is progressive, so the passive must be progressive too. Note also that my pet dog after by is the agent — the doer — not the object.
3. The tense a single word decides
Given: Veronica does not have to help out with the house chores. She did not have to do all that even when she was young. Frame: Since ______
→ Since Veronica was young, she has not had to help out with the house chores.
Read Since as from the time when, never as because. It marks a span that starts in the past and is still true now, and English marks that span with the present perfect. did not have to describes a finished period and drops the continuing relevance.
4. The nominalisation
Given: Henry was completely surprised that he had won the top prize in the singing competition. Frame: To ______
→ To Henry's complete surprise, he had won the top prize in the singing competition.
Both words change class together: completely (adverb) becomes complete (adjective), and surprised (adjective) becomes surprise (noun). Children who convert only one of the two produce To Henry's completely surprise, which is the same error in a different coat.
5. The plural that is not plural
Given: All the players train extremely hard during the weekly practice. Bobby and James do not. Frame: Every one of the players except ______
→ Every one of the players except Bobby and James trains extremely hard during the weekly practice.
The subject is Every one, which is singular, so the verb is trains. Bobby and James sits inside an exception phrase and never touches the verb. There is also no comma before except, so there cannot be one after James — punctuation is marked here as well as grammar.
The Single Most Commonly Lost Mark
One item type accounts for more lost marks than any other, and it is lost by pupils who know their grammar well.
Given: Sheryl could not get the jar open. She tried even harder.
Frame: However ______
Almost every child writes this:
✗ However, Sheryl could not get the jar open.
It is grammatical. It reads naturally. It is wrong — because it treats However as a linking word and throws the second sentence away entirely. Rule 2 above is the one being broken.
The marked answer is:
✓ However hard Sheryl tried, she could not get the jar open.
Here However is a degree adverb, not a connector, and it takes a fixed shape: However + adjective or adverb + subject + verb. However hard she tried. However quickly he ran. However late it was. Once a child has seen the shape once, the item becomes one of the easier marks on the paper — which is precisely why it is worth practising deliberately.
The four items above share one feature, and it is the reason they are so often missed.
Synthesis and Transformation at P5 and P6: What Changes?
The families are the same at both levels. The difficulty moves in three ways.
P5 | P6 | |
Transformations per item | Usually one | Often two at once — a nominalisation and a negation |
Passive forms | Mostly simple past | Progressive, perfect and modal passives are all examinable |
Reported speech | Direct → reported | Both directions, and reversing is harder than converting |
The reverse direction deserves a word, because it is where a strong P5 pupil first stumbles at P6. Going from reported speech back to direct speech means undoing several changes at once — pronoun, tense and time reference — and the pupil has to remember to restore the auxiliary and the closing quotation mark as well.
The Three-Word Self-Check
For any reported-speech item, three words catch almost everything: pronoun, tense, time. Across one P6 exercise, a pronoun change was required in five items out of five, a tense change in five out of five, and a time change in four out of five — the exception being the one item with no time reference at all.
So the check is simply: have I changed the pronoun? the tense? the time? If a required change has not been made, the answer is incomplete, whatever it sounds like. That is a faster and more reliable proof-read than reading the sentence back to see whether it "sounds right" — because the wrong answers in this section almost always sound right. That is what makes them wrong answers.
If Your Child Keeps Losing These Marks
Look at which step is being missed rather than at the number of marks lost. In our experience the loss is almost never vocabulary. It is one of four things: the frame was not read as an instruction, the second sentence was not used, only one of two required changes was made, or the meaning quietly shifted. Each has a different fix, and a child who is told only "practise more" gets none of them.
We teach synthesis and transformation as a set of recognisable families with a decision to make in each, rather than as a list of rules to memorise, in our P5 and P6 English programmes at AGrader. If you would like to see how your child handles the four steps above, book a free trial at agrader.sg.
