I'm keen on swimming, because I find it’s so cool and relaxing. In summer days, it's always very hot. We can’t do any sports but swim. While swimming, I can entertain myself. I began to learn swimming when I was eight years old. I was a quick learner. After three weeks learning, I could swim very well. So I often went swimming with my friends in my free time. But now I'm tired of swimming pools. I dream of swimming in the sea.
