Step-by-step explanation:
The given sentences are an example of the first conditional. The first conditional consists of two clauses. The first clause contains the present simple tense after if, while the second clause contains the future simple tense:
- If + present simple, ... future simple.
We use this form when we talk about things that might happen in the future.
For example:
- If a cat washes behind its ear - if + present simple
- It will rain - future simple
The rest of the examples are solved the same way.
