| 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. | 1._________ 2.________ 3.________ 4.________ 5.________ 6._________ 7._________ 8.________ 9._______ 10._________ |
