In summer, the weather is very hot. People like swimming because water makes them feel cool. If you like swimming and swim in a wrong place, it may not be safe. Every year, some people die(死亡) when they are swimming in rivers, and most of them are students. But still a lot of people are not careful(小心的) in swimming. They often think they swim so well that nothing can happen (发生) to them in rivers. It’s summer now. If you go swimming, don’t forget that some good swimmers die in rivers. They die because they are not careful, not because they can’t swim well. So don't get into rivers when you are alone(单独的), especially when there is a “No swimming!” sign.
