It is well known that exercise is important. In our school, we have to do an hour's exercise every day. Many students are very happy. In the one hour, some of us play basketball, football and ping pong, and some run around the playground. Everyone is talking and laughing. I love this activity very much. I also hope that there will be more and more sunlight sports in our life after school. That not only makes us happy, but also makes our body healthier.
