Synthesis and transformation: same meaning, new shape
You are given a sentence and a word or phrase to build a new one round. The meaning must stay exactly the same — and almost every lost mark is a meaning that quietly changed.

01 The rule underneath all of it
The new sentence must mean the same as the old one. Not nearly, not roughly. Every fact in the original must survive, and nothing new may appear.
So the safe method is: work out what the original says, then build a sentence that says all of it using the word you were given.
Then read your sentence on its own, without looking at the original, and ask whether it still says the same thing.
02 The joining words and what each signals
The word you are given tells you the relationship the new sentence must show.
| Given word | Shows | Watch for |
|---|---|---|
| although / even though | contrast | no 'but' as well |
| because / since / as | reason | cause before effect |
| so that / in order to | purpose | not the same as 'so' |
| too … to / enough to | degree | meaning flips if misplaced |
| unless / if | condition | unless already means 'if not' |
| despite / in spite of | contrast | followed by a noun, not a clause |
03 The transformations that come up
A handful, and each has its own trap.
- Active to passive. The dog chased the cat → The cat was chased by the dog. Keep the tense; the object moves to the front.
- Direct to reported speech. “I am tired,” she said → She said that she was tired. Tense shifts back, pronouns change, and quotation marks go.
- Too … to / enough to. He is too short to reach it means he cannot reach it; tall enough to reach it means he can. Getting these round the wrong way reverses the meaning entirely.
- Unless. Unless you hurry, you will be late already contains the negative. Writing unless you do not hurry reverses it.
- Joining two sentences. Keep both facts, remove the repetition, and do not add anything.
04 Checking your answer
Four checks, in this order, catch nearly everything.
- Is every fact from the original still there? Missing one is the commonest error.
- Has anything new appeared? Adding a reason the original did not give is marked wrong.
- Did you use the given word, in the form given? If it was although, though is not it.
- Is the tense the same? Unless the transformation requires a shift, as reported speech does.
- Read it aloud in your head. A sentence that is grammatically wrong loses the mark even if the meaning survived.
05 How to say them
These are words most children have never said out loud, and a word you cannot say is a word you avoid using. Capitals mark the syllable you lean on. Tap the speaker to hear it.

07 Mistakes worth knowing about
Each of these is wrong. Decide why before you open it.
“Although he was tired, but he kept working.”
Although already carries the contrast. Using but as well is one connector too many.
“He is too short to reach it” → “He is short enough to reach it.”
Those mean opposite things. Too … to means cannot; enough to means can.
“Unless you do not hurry, you will be late.”
Unless already means if not. The double negative reverses the meaning.
“Despite he was tired, he kept working.”
Despite is followed by a noun or -ing: despite his tiredness, or despite being tired.
“I made it shorter and clearer.”
Clearer is not the task. The meaning must be identical, including every fact the original gave.
