We would have gone with him if we had known about his small car
If you had studied, you would have passed your exams.
You will grow up quicky if you drank a lot of milk
If you won that contest, I will be very happy
I will go with you tonight if my parents let me
If you don't treat the dog kindly, he will bite you.
