Swimming is very popular. People like swimming in summer because water makes people feel cool. If you swim in a wrong place, it may not be safe. These years, a lot of people died when they were enjoying themselves in the water, and most of them were students. But some people are still not careful when swimming. They often think they can swim so well that nothing will happen to them when they are swimming. Summer is here again. If you go swimming in summer, don ' t forget that many better swimmers have died in the water. They died because they were not careful, not because they could not swim. So don't get into water when you are alone. If there is a "No Swimming" sign, don't get into water, either. If you remember these, swimming will be safer.
