参考范文

     Health is very important to us teenagers. Either study or work is based on strong body. Doing sports every day helps us keep healthy and energetic. And taking exercise can keep us strong, we won’t get tired or sick easily. Just as the slogan says, “Exercise one hour a day keeps illness away.”

     There are many kinds of sports we can do, such as running, swimming and ball games. Now we students have to do too much homework after school. I hope teachers will leave us less home work so that we can have more time to take part in sports. I also hope our school can organize more sport activities for us.
