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