Revision of first type conditional sentences

The first conditional is also called the "real" conditional because it is used for real, or possible, situations. These situations take place if a certain condition is met.
In the first conditional we can salso use unless, which means "if... not". In other words, "... unless he hurries up" could also be written, "... if he doesn't hurry up."

• If it rains, we will stay at home.
• He will arrive late unless he hurries up.
• Sophie will buy a new car, if he gets his raise.

The first conditional is formed by the use of the present simple in the if clause followed by a comma and a future simple verb (will + infinitive) in the result clause. You can also put the result clause first without using a comma between the clauses.

• If he finishes on time, we will go to the movies.

OR

• We will go to the movies if he finishes on time.
