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 make them keep healthy. But sometimes it’s also dangerous if you don’t know how to keep safe (安全的)when swimming.
If you swim in a wrong place, it may not be safe. A lot of people died(死) when they were enjoying themselves in the water, and most of them were 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.
