If you don't study hard, you will not pass this exam. You will be healthy, if you don't leave home. If Helen hasn't heard the bad news yet, I will tell her. If we don't sign the contract, we will have wasted a lot of time and money. If you don't hurry up, you will be late. If you can't do that task in maths, I will help you. We will not go to the cinema, if it rains. If you don't come in time, I won't can to meet you.
