Tom,

I'd like to tell you something more about our school sports meet. It was holding on Oct. 6, which was a fine day. There were over 1,000 students and teachers attend it. Wang Lin, a student from my class won the 100-meters 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 cone. I’m looking forward to receiving your letter.
