Many people like to swim in summer. So do I. My favorite sport is swimming. Just imagine! What fun it is to jump into the water in hot summer! In hot weather，I often go to swim in the swimming pool with my family. Swimming can not only make us strong and healthy，but also helps us to keep in good shape. But few people like to swim in winter because it is too cold.Swimming in winter needs much courage. I hope one day I can be strong enough to swim in winter.
