Dear Wang Hong,
I am an American school girl. My name is Alice Green. I am twelve. There are five people in my family-my brothers, my parents and I. My brothers and I are all students at the same school. We go to school from Monday to Friday. We don't have any classes on Sundays or Saturdays. My father and mother are teachers. They say, China is great, and  Chinese people are friendly, I want to travel in China. I think it is very interesting, isn't it? I like reading. Now I am reading a book of Chinese stories. They are very interesting. My brothers and I like playing soccer and basketball. What do you like?
Let's be friends. Please write soon.
Yours,
Alice Green
