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 his-tory．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
