Sentence Transformation Drill
grammarwritingaccuracypracticepairslow prep15-20 min
Cambridge FCE/CAE/CPE Use of English features key-word transformations: a sentence, a prompt word, and a word-count constraint. Learners rewrite using the prompt without changing meaning. This drill sharpens the technique.
The Task Format
Original: She regrets not studying harder at school.
Key word: WISHES
Rewrite: She … at school.
(5 words including the key word)
Answer: wishes (that) she had studied harderProcedure
- Technique brief (5 min):
- Identify the grammar transformation: the key word signals which structure (wish/unreal past, as if/comparison, since/time, etc.).
- Change as little vocabulary as possible beyond the prompted structure.
- Count words carefully; contractions count as two (didn't = did not = 2 words).
- Pair drill (10 min): take 8 items together. For each:
- Student A identifies the target grammar point.
- Student B writes the transformation.
- Both check word count and meaning preservation.
- Swap roles for the next item.
- Solo set (5 min): 6 fresh items, individual, timed.
- Common errors review: share the items most pairs got wrong.
Grammar Categories Most Tested
| Category | Trigger words |
|---|---|
| Passive | BY, WAS, WERE, HAD |
| Reported speech | SAID, TOLD, ASKED, WHETHER |
| Modal perfects | MUST, COULD, SHOULD, MIGHT |
| Wishes / regrets | WISH, IF ONLY, HAD |
| Conditionals | UNLESS, IF, PROVIDED |
| Inversion | NOT, HARDLY, NEVER, NO SOONER |
| Causatives | HAD, GET, MADE |
| Participle clauses | HAVING, BEING |
| Cleft sentences | WHAT, IT |
Why It Works
- Exam-specific fluency: transformation is a distinct skill from general grammar; needs direct practice.
- Grammar system review: 20 items cover most of the B2–C1 grammar inventory.
- Word-count discipline: a common failure mode; this drill trains it.
Variations
- No word-count version: students write the transformation first; count and adjust second. Isolates the grammar from the constraint.
- Write-your-own items: pairs create 5 transformations for another pair. Forces deep understanding.
- Category-locked: a set of 10 items all target the same structure (passive, or reported speech). Deep drill.
Tips
- The word-count trap catches half of students' wrong answers. Teach them to count before claiming done.
- Build a transformation cheat sheet: one-line note for each grammar category's typical trigger. Fits on a bookmark.
- These drills are equally useful outside Cambridge exams — good general grammar review for B2+ learners.
