C)阅读短文，根据短文内容选择正确的答案。
Swimming is very popular in the world. People like swimming in summer，even in the other three seasons，because water makes people feel cool and swimming makes people healthy.
If you swim in a wrong place，it may not be safe. A lot of people died when they swam in the water，and some of them were students. Last summer，a few students from one school went to swim in the river near their school. However，three of them never came out from the river.
Now some people are not careful enough in swimming. They often think they can swim very well. And they think nothing will happen in water.
Summer is here again. If you go swimming in summer，don't forget that a lot of good swimmers had accidents in water. They had accidents not because they couldn't swim，but because they were too careless(粗心大意的). Don't get into water when you are alone. If there is a “No swimming” sign，don't get into water. If you remember these，swimming will be safe and fun.
