Swimming is the best thing in summer. I can get cool when swimming and make me fit well. In the 20xx London Olympics,I watched YangSun and ShiwenYe who come from China have got gold medals. IT was a big suprise in China,and more and more peple will like swimming .Besides,swimming is my favorite hobby,and it's a good sport for me to get stronger. I often go swimming, usually twice a week in summer. Of course, I have my favorite swimming athlete-he's Phelps. From swimming, I learn 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. As one of the popular sports,more and more parents send their children to learn swimming. They hope that their children can grow up healthy.Therefore i think swimming will become important like sleeping in the future.
