If you heat water to 100° C,
If you had been able to afford it,
If Rachel had more time,
If I won the lottery,
If Bill studies,
If I don’t practice the piano everyday,
Will you take the train
Suzanne wouldn’t have had the heart attack
she would learn to play the guitar
I would travel around the world
if you miss the bus?
it boils
would you have liked to go to university?
if she had gone on a diet as her doctor recommended
he will pass the exam
I play poorly
