Hello! Welcome to our program! I’m John. I’m in a health club now. I’m having a talk with four students. They are members of this club.

Enough sports are good for relaxation（放松）and can make people strong and clever. If you do sports every day, you can get good grades（成绩）in the exam（考试）and do homework well.

There are many ways to exercise. You can walk, run, swim, or play ball games. But remember: exercise enough, but not too much. It’s best to exercise thirty minutes every time.

In fact（事实上）, students spend（花费）most of their time on study and don’t do enough sports. They can feel tired and bored（厌烦的）. If they feel tired, they will want to sleep. When they feel sleepy, they can’t study well.

Parents and teachers must pay more attention to the students’ health.

Swimming is a very popular game in the world. Many people like swimming in summer, and in the other three seasons too. They think water makes them feel cool and swimming makes them keep healthy. But sometimes it’s also not safe if you don’t know how to keep safe when swimming.

If you swim in a wrong place, it may not be safe. A lot of people die (死) when they are enjoying themselves in the water, and most of them are students. Now some people are not careful in swimming. They often think they can swim very well, so nothing will happen to them in water.

If you go swimming in summer, remembering the following rules will be very useful. Don’t get into water when you are by yourself. If there is a “No swimming” sign, don’t get into water. If you remember these, swimming will be safe and enjoyable.
