Finn says
If sentences help you talk about real and imaginary situations – perfect for Speaking Part 4 ('What would you do if…?'). Learn three patterns and you're ready!

Common mistakes
- ✗ If it will rain, we'll stay in.✓ If it rains, we'll stay in.No 'will' after 'if'.
- ✗ If I would have time, I would help.✓ If I had time, I would help.No 'would' after 'if' – use the past simple.
- ✗ Unless you don't hurry, we'll be late.✓ Unless you hurry, we'll be late.'Unless' is already negative.

Finn's exam tip
Never put 'will' or 'would' straight after 'if'. The 'will' or 'would' goes in the other half of the sentence.
