     Swimming is a good sport and it's very popular. In summer people like swimming because water makes

people feel cool. If they swim in a wrong place, it may not be safe. These years, some people died when they

were enjoying themselves in water and most of them were students. These people were not careful in

swimming. They often thought they swam so well that nothing would happen to them in water.

      Summer holiday will be here again. If you go swimming, don't forget that better swimmers often died in

water. They died because they were not careful, not because they could not swim. So don't get into the water

when you are alone. Don't get into the water if there is a "No swimming" sign. If you remember these,

swimming will be safe and it's good for your health.
