We use the zero conditional to talk about something that is always true or always happens as a result of something else.
You can use the simple present, present continuous or present perfect in either clause.
We use the first conditional to talk about something that will probably happen in the future.
You can use any present form in the if – clause ( simple present, present continuous or present perfect) and any future form ( will going to, future perfect, future continuous) or an imperative or a modal verb (might, may or should) in the other clause.
When we have negative if-clauses, we can replace if not with the word unless.
We can replace the word if in the if-clause with a future time expression to give more details about the future.
