FCE Key Word Transformations: Tips & Practice

Key Word Transformations are part of Reading and Use of English, Part 4 of the B2 First (FCE) exam. You are given a sentence, a key word, and a second sentence with a gap. Your task is to complete the second sentence so that it has the same meaning as the first one, without changing the key word. You must use between two and five words, including the key word.

This task is not simply about knowing grammar rules. It tests whether you can recognise and produce different ways of expressing the same idea. The transformations can involve a wide range of language points, including verb patterns, tenses, conditionals, modal verbs, passive structures, reported speech, comparisons, phrasal verbs, collocations and fixed expressions.

How to approach FCE Key Word Transformations

When you see a transformation, don't immediately try to fill the gap. A more effective strategy is to work through the sentence systematically:

1. Read the whole sentence carefully. Make sure you understand its exact meaning before you start changing anything.

2. Look at the key word. Think about common structures and expressions that use it. Remember: you cannot change the word in any way.

3. Identify what has changed between the two sentences. Is the second sentence testing a different tense, a passive structure, a conditional, a verb pattern, a phrasal verb or a particular collocation?

4. Build the transformation in your head first. Don't worry about the gap until you know what structure you need.

5. Check the number of words. Your answer must contain 2–5 words, and the key word counts as one of them.

6. Read both sentences again. They should mean exactly the same thing. Small differences in meaning can cost you the point.

7. Check the grammar and spelling. In this part of the exam, accuracy matters.

A useful habit is to learn language patterns rather than isolated words. For example, don't just learn suggest. Learn the structures suggest doing something and suggest that someone do something. Don't just learn look forward; learn look forward to doing something. These are the patterns that often make the difference in a transformation task.

Test yourself

The best way to prepare for Part 4 is not just to read lists of possible transformations. You need to actively practise recognising the language point and producing the structure yourself.

To help you do that, I've prepared a set of 50 FCE-style Key Word Transformations, covering many of the language points that commonly appear in this part of the exam. Try to complete them without looking at the answers first. Give yourself enough time to think about each one, and check not only whether your answer is correct, but also why that particular transformation works.

Exam hack

Once you've checked your answers, make a note of the structures you found difficult. Those are the ones worth revisiting - because in the exam, recognising the underlying language pattern quickly is often more important than simply knowing a grammar rule.
