阅读理解。

     Swimming is very popular in summer. People like swimming in summer because water makes them

feel cool. If you swim in a wrong place, it may not be safe.  These years,  more than ten people died in

this city while they were enjoying themselves in the water and most of them were students.

      But some people are  still  not careful while  swimming.  They  often think they swim so well that

nothing can happen to them in water. Summer is here again. If you go swimming, don't forget that lots

of swimmers have died in water.They died because they were not careful, not because they were not

good at swimming. So don't get into water when you are alone. If there is a "No swimming" sign, don't

get into water, either. If you remember all these, swimming will be safe,
