I went with several of my classmates to play badminton on last weekend.When they got to the sports ground,it was full in people.We waited patient for our turn for an hour.At first,we play singles.After about half hour,Li Ming suggested playing doubles,but we all agreed.Liu Qiang and I was in a team.Both of us tried our best and finally our group beat the other three team.From this sports exercise I learned what important teamwork is.
