If, when

Lesson 18

If I have money, I will buy it.
When I have money, I will buy it.

When we speak about the future, we use the present simple after if and when.

Examples

If you come at four, I will be happy.
If you travel a lot, this information will help you.
When I leave you, you will be sad.
When you look at the stars, you will smile.
