     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 day. We hope that we'll be giving less homework
and have more time takepart in sports. We also hope
that our school can hold sports meeting every term.
