　　Dear Jenny，

　　I am very busy on Monday．At 7：30I have English，It's difficult but interesting．Then at 9：00I have science．It is very fun．I like it very much．At 10：00I have P．E．It is my favorite subject．After that，I have Chinese at 11：00．It's difficult but useful．Lunch is from 12：00to 1：00，and after that we have history．My history teacher，Mr．Li，is great fun．My classes finish at 4：00，but after that I have an art lesson for two hours．It is so easy!

　　Your friend，

　　David
