Boys and girls,
It is very important for us students to keep healthy.
There are many ways to be healthy. We’d better eat more fruits and vegetables. Take exercise for at least one hour every day. We need enough sleep and rest so it is important to go to bed early and get up early. Besides, we should wash our hands as often as possible. In my opinion, we mustn't drink wine or smoke .They are bad for our health.
