It was holding on Oct. 6th, which was a fine day. There was over 1,000 students and teachers attend it. Wang Lin, a student from my class won the 100-meter race. He finish the race in 12.6 seconds and broke in the school record. The sports meet was really success. That was because we were all trying to do my best. Although I was not one of the winner, I was proud of that we had done. Looking forward to receiving your letter. Yours, Li Ping 1._________ 2._________ 3._________ 4._________ 5._________ 6._________ 7._________ 8._________ 9._________ 10._________ 查看答案
