Dear Jim,

I'd like to tell you something more about our school sports meet. It was holding on Oct. 6th, it was a fine day. There were over 1,000 students and teachers attended it. Wang Lin, a student from my class won the 100-meters race. He finished the race in 12.6 seconds and broke 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 receive your letter.

Yours, Li Ping
