First Conditional Exercise 3

The first conditional is an if-sentence in English that is used to talk about realistic situations in the present and future. There is a condition and the result of that condition when it is fulfilled. The verb in the if-clause needs to be in the present simple and the verb in the main clause has to be in the will-future (will + infinitive).

This is an exercise in which you must fill in the correct verb form.
