Dear Huanhuan,
I'm happy to write to you. I'm very busy on Friday. At 8. 00, I have Chinese. It's fun. Then at 9:00, I have a math lesson for two hours. The teacher says it is useful, but I think it is difficult. After lunch, we have English. It's my favorite subject. Ms. Hand, our English teacher, is great! We have a good time every class.
Oh. I also have some good things to tell you. Next month, we have a school trip on January 12th. We go skating(滑雪)in Jingyue Park. And we have an art festival on January 18th, They are really cool for me I can't wait! (等不及了)
Well, how about you? What's your favorite subject? And what activities do you have? Tell me soon!
Best wishes!
Amy
