Dear Jenny,

     At 8:00 a.m.. I have math. It is not fun. The teacher says it is useful, but I think it is difficult. Then at 9:00 in the morning, I have science.  At 10:00 a.m. I have history.  It is easy and fun. Lunch is from 12:00 to 1:00 p.m., and after that we have Chinese. It is my favorite subject.  My classes finish at 1:50 p.m., but after that I have an art lesson for two hours. It is really relaxing! 

    How about you?  What is your favorite subject?

Your friend,

Yu Mei
