Dear Jim,                                             
    I'd like to tell you something more about our school  
sports meet. 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,
