（2015•温州市高三第二次适应性测试） My favorite sport is playing basketball. In the middle school, I joined in the basketball team. All the teammate practised hard after school. Once our team had match against another school’s. At the very beginning, we were so nervous which we couldn’t cooperate very good, because this was the first time for us to compete with the school honor. In the half match they fell behind. Our team leader calls us together and said that we must get uniting in order to beat them. Then we tried  our best and won the game at last. Play basketball makes me realize the importance of union and teamwork.
