It is very important for us to do sports.We can exercise and enhance physical fitness by doing sports.I often do sports.And I like playing basketball very much becsuse we can exercise our ability to respond and foster co-awareness.I often play basketball with my friends in P.E.class.We often play basketball twice a week----on Tuesday and Friday afternoon.And every time we spend about 40 minutes in playing basketball.I am very tired after playing basketball,but I feel very happy.
