Conditional sentences express a choice and the possible consequences of that choice.
There are three types of conditional sentences: Real, Unreal and Unreal Past.
The first type is the easiest to learn. It involves a present choice and a future consequence.
- If you drive north for three miles, you will get to Columbus.
- If he doesn’t exercise, Fred will gain weight.
- If you purchase a raffle ticket, you might win a car.
Real conditional sentences contain two parts, the if clause, and the result clause.
The if clause indicates the choice and is expressed in present tense.
