What are Key Word Transformations?

Key Word Transformations is Part 4 of Use of English in First Certificate (B2) and Advanced (C1). You must complete six transformations using a given key word, keeping the meaning exactly the same. You may use 2–5 words (B2) or 3–6 words (C1) including the key word, which you must not change.

Common transformation types

Frequent patterns

1. Expressions with 'make' and 'let'

Transformations with causative structures.

Examples:
  • He forced me to go → made me go
  • She allowed me to leave → let me leave
  • They didn't allow smoking → wouldn't let people smoke
  • The teacher made us study → forced us to study

2. Conditionals and 'wish'

Hypothetical structures and wishes.

Examples:
  • I regret not studying → wish I had studied
  • It's a pity you can't come → wish you could come
  • If only I were taller → wish I were taller
  • I should have listened → wish I had listened

3. Comparisons and superlatives

Different ways to express comparisons.

Examples:
  • No one is taller → the tallest person
  • Nothing is more important → the most important thing
  • I've never seen anything better → the best thing I've ever seen
  • She's not as tall as → shorter than

Problem-solving strategies

1. Analyse the meaning

Understand exactly what the first sentence means.

Examples:
  • Identify subject and object
  • Recognise the tense
  • Note register (formal/informal)
  • Watch for negation or emphasis

2. Identify the transformation needed

Decide what kind of structural change you need.

Examples:
  • Tense shift?
  • Active to passive or the reverse?
  • A different grammatical pattern?
  • An equivalent idiomatic expression?

3. Build around the key word

Use the key word as the centre of your answer.

Examples:
  • What pattern does this word require?
  • Which prepositions go with it?
  • Which tense does it need?
  • How does it fit the gap?

Frequent exam patterns

Most common transformations (B2/C1)

Structures that appear regularly in exams.

Examples:
  • Wish + past perfect: 'I regret...' → 'I wish I had...'
  • So/such + that: 'very tired' → 'so tired that'
  • Have something done: 'Someone repaired' → 'had it repaired'
  • It's time + past simple: 'should go' → 'it's time we went'

Frequent key words

Words that often appear as key words.

Examples:
  • WISH (regret, hypothetical situations)
  • RATHER (preferences: would rather, rather than)
  • POINT (there's no point, what's the point)
  • SOONER (no sooner, would sooner)

Time management (15–20 minutes)

Timing strategy for this section.

Examples:
  • Spend at most 2–3 minutes per transformation
  • If you are stuck, move on
  • Leave 3–4 minutes for a final check
  • Write something even if you are not sure
