     Swimming is very popular. 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, a lot of people died

when they were enjoying themselves in the water, and most of them were students. But some people are

not careful in swimming. They  often  thinks  they  can  swim  so  well that nothing will happen to them in

water.

     If you go swimming in summer, don't  forget  that better swimmers  have  died  in  water. They died

because they were not careful, not because they could not swim. So don't get into water when you are

alone. If there is a "No swimming" sign, still don't get into water. If you remember these, swimming will

be safe.
