zero-first, second and third conditional -explanation and exercises

 

The Zero Conditional

We use the zero conditional to talk about permanent truths, such as scientific facts, and general habits. The structure is simple:

If you heat water to 100°, it boils.

If I’m tired, I go to bed early.

The First Conditional

We use the first conditional to talk about a realistic situation in the present or future. The structure of the first conditional is as follows

If it's sunny, I'll go out

If he studies hard, he’ll pass his exam.

He’ll call you if he needs help.

The Second Conditional

We use the second conditional to talk about improbable or impossible situations in the present or future. Here is the structure:

If I were rich, I’d spend all my time travelling.

If he didn’t have to study, he would go out with his girlfriend.

The Third Conditional

We use the third conditional to talk about impossible situations, as in the second conditional, in the past. We often use the third conditional to describe regrets. The structure is:

If we had left earlier, we would have arrived on time.

If you hadn’t forgotten her birthday, she wouldn’t have been upset.
