语言素材：
Dear Jenny,
I am very busy on Friday. At 8:00 I have math. It is not fun. The teacher says it is useful, but I think it is difficult. Then at 9:00 I have science. It is difficult but interesting. At 10:00 I have history. After that, I have P.E. at 11:00. It's easy and fun. Lunch is from 12:00 to 1:00, and after that we have Chinese. It is my favorite subject. Our Chinese teacher, Mr. Wang, is great fun. My classes finish at 1:50, but after that I have an art lesson for two hours. It is really relaxing! How about you? When are your classes? What is your favorite subject? Your friend, Yu Mei
