I will earn a lot of money, if i get that job
If she doesn't hurry, we will miss the bus
If he tried harder, he would reach his goals
I would buy these shoes, if they fitted
It wouldn't suprise me, if he didn't know the answer
If we had listened to the radio, we would have heard the news
If you had switched on the light, you wouldn't have fallen over the chair
She would have come to our party, if she hadn't been on holiday
