     We all know that healthy is very important to us. Both study and work depend by strong bodies.

Doing sports and games help us keep strong and healthy. If we do not take any exercise, we may

feel tired but get sick easily. There're many different kinds of sports we can do them, such as playing

ball games, running, walking and swim. However, now we have too much homework to do in every

that our school can hold a sport meeting every term.
