Conditionals
- Zero: general truths — If you heat ice, it melts.
- First: real future — If it rains, we will stay home.
- Second: unreal/imaginary — If I were rich, I would travel.
Key idea
The zero conditional states facts, the first a real future possibility, and the second an unreal situation.
Remember
The second conditional uses 'were' and 'would' for imaginary situations.
