Swimming is the best thing in summer. I can get cool when swimming and keep me healthy.

At the 20 12 London Olympic Games, I saw Sun Yang and Ye Shiwen from China win gold medals. This is a big surprise in China. More and more people will like swimming.

Besides, swimming is my favorite hobby, and it is a good exercise for me to keep fit. I often go swimming, usually twice a week in summer. Of course, I have my favorite swimmer-he is Phelps. From swimming, I learned that the more we practice, the better we can do. My parents think swimming is a good hobby, and they encourage me to swim better.
