Summer holiday is coming. And swimming safety becomes a big problem. Swimming is a great way to keep fit and relax. However not every place is suitable (合适的) for us to swim. There is some advice (建议) for you.
Swimming pool is a good place to swim. You'd better don't swim in a deep river. Also, you can't go swimming alone (单独的). You'd better go with your parents. Before you swim, you should get ready for it instead of (代替) jumping into the water in a hurry. Of course, you shouldn't swim for too long so that you won't feel tired.
In short, only one life. We must keep away from danger and cherish life.
