答案

I'm glad I've made up my mind to play basketball. There are some reasons. Firstly, it's a good game to burn my calorie. Take myself for example. I was almost 200 pounds last year and when I realized I had to lose weight, I started to play basketball. After a year, I've lost over 70 pounds. What a nice hit! Moreover, it's a game to make friends. Basketball, as is known to all, is a game requires a good sense of teamwork and cooperation. So it is the case with my partner Tim and me. We cooperate well in the game, so we become friends. And the deeper the friendship is, the better we cooperate.
