Preferences: prefer and would rather
Prefer A to B, prefer -ing to -ing, would prefer to, would rather and would sooner … than.

There are several ways to say what you like more, and each one has its own grammar. Part 4 often asks you to change one into another – so let's compare them side by side.
General preferences
Things you usually like more.
In a particular situation
What you want now, or on one occasion.
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 (2–5 words).
PREFER
I prefer reading to watching TV.
Prefer + -ing + to + -ing.
RATHER
I would rather take the train.
Would prefer to = would rather + infinitive without to.
SOONER
I would sooner cook at home than eat out.
Would sooner + infinitive … than + infinitive.
Common mistakes
- ✗ I prefer tea than coffee.✓ I prefer tea to coffee.Prefer A to B.
- ✗ I'd rather to stay at home.✓ I'd rather stay at home.No 'to' after would rather.
- ✗ I'd prefer staying in tonight.✓ I'd prefer to stay in tonight.Would prefer + to-infinitive.

Ask yourself: is it a general preference (prefer) or a particular situation (would rather / would prefer)? Then check the verb form: prefer -ing to -ing, would rather + infinitive, would prefer + to.
Quick check
