My Favorite Sport
Sports are an important part of my life. I not only like watching the sports games, but also like playing sports. My favorite sport is basketball. Firstly, it can help me to keep healthy and happy. Secondly, I can make a lot of friends through playing basketball and we can share our successes and failures. I can also learn a lot from playing basketball with others, and it makes me understand that there is no “I” in the team. And every player should cooperate with other players in the team. So, I insist on playing it with my friends and classmates every day.
