Swimming is a good sport.It's popular.People like swimming because the water
makes people feel cool.But if they swim in a wrong place,it is very dangerous.
These years,some people died when they were enjoying themselves in water and
most of them were students.Summer holiday will be there again.I want to give
you some advice.First,don't get into the water when you are alone.Second,
don't get into the water if there is a No swimming sign.Third,you should be
careful in the water.If you remember these,swimming will be safe and it's good
for your health.
