She would travel all over the world if she were rich.
She would pass the exam if she studied.
If I had his number, I would call him.
If I were you, I wouldn't go out with that man.
If the weather wasn't so bad, we would go to the park.
If you went to bed earlier you wouldn't be so tired.
If she fell, she would hurt herself.
If I found her address, I would send her an invitation.
