Icono de iDevice Solved exercise

We've already learned the form of first conditional sentences. Let's learn about their use:

We use first conditional sentences to talk about a possible or likely event and its result.

The 'if' clause can go at the beginning or at the end of the sentence, and they have the same meaning:

CONDITION RESULT
If I study,
I will pass my exams

 

RESULT CONDITION
I will pass my exams
 if I study
What happens if we put the 'if' clause at the beginning?

Don't forget you are using the Present Simple in first conditional sentences, so don't forget the -s of the third person singular, or the auxiliaries do/ does, don't/doesn't for the negative or interrogative forms!
