English composition: Suppose you are Li Hua, a middle school student. You have an appointment with Tom, an English friend from Shanghai, to travel to Beijing next weekend, but you can't keep the appointment for some reason. Please write him a letter.
Dear Tom:
I'm sorry that I can't travel to Beijing with you next weekend. Because I have a lot of homework this weekend. (Essay) How about going there? If not. Have a nice trip. If you want to go next week, have a nice trip.
Your friend
Ilhua
