答案
Sports meeting
Every year, my school holds sports meeting in about October, I am very exciting about it, I can watch the wonderful game and don’t have class. My school’s sports meeting lasts three days, the class is suspended, all the students go to the play ground to watch the game. As an audience, I am so nervous and yell out “come on” to my classmate, watching they get to the final line, I am so proud of them. The part I like most is relay race, that is so exciting, all the students yell loudly, the athletes chase one by one, nobody can be sure who is the champion until the last minute. Sports meeting bring me so many beautiful memories.
