Fixed expressions
Come as a surprise, take by surprise, keep someone in the dark, at short notice, live up to and more.

Many C1 Part 4 answers are fixed expressions: you can't work them out with grammar – you just have to know them. Learn them in small groups with an example, and they'll stick!
Surprise, attention and knowledge
Expectations and chances
Time, amounts and other favourites
How it comes up in Part 4
In Part 4 you complete the second sentence with the key word, so that it means the same as the first one (3–6 words).
DARK
We were kept in the dark about the changes.
Keep someone in the dark = not tell them. Here it is passive: were kept.
LIVE
The holiday didn't live up to our expectations.
Live up to expectations = be as good as expected.
BOUND
The train is bound to be late.
Be bound to = be certain to.
Common mistakes
- ✗ The news came as surprise to me.✓ The news came as a surprise to me.Don't drop the article in a fixed expression.
- ✗ He didn't pay attention at my advice.✓ He didn't pay attention to my advice.Learn the preposition with the expression.
- ✗ The hotel didn't live up our expectations.✓ The hotel didn't live up to our expectations.Live up to – all three words.

Keep a notebook of expressions with their preposition and an example sentence. In the exam, if grammar alone doesn't explain the answer, the key word is probably part of a fixed expression.
