| I am writing this story to express the important value of sportsmanship. Some years ago, my traveling 1 team took part in a nationwide competition. This competition is very 2 and the atmosphere is far from 3 . After we completed our performance, the next competing team laughed at us and gave us a dirty 4 as we passed them. They looked 5 at us and made fun of our costumes and our performance. My team and I were all very 6 , even to the point of tears. One of my team members 7 that we should “boo（发嘘声）"them as they performed. Finally I said, “Let’s teach them a lesson.” My teammates all looked at me. I was the oldest member of the team and their role model. What I said next totally 8 them. I said, “They are on stage right now. Let’s go and 9 them.” I then looked up at the stage and started to scream, “Come on!” My teammates all started to shout loudly with me to show support for the team. At first they were 10 . Then I noticed that they were having 11 screaming for the team that a couple of minutes before they hated. When the team finished dancing and walked off stage, my teammates and I all started to 12 them. Most members of the opposite team 13 and said “thank you”, and they were a little embarrassed. My team and I felt a lot better about the 14 . After that, my teammates understood what a great 15 it was and they were glad that they had shown good sportsmanship. | ||||
