Dear Amy,
I'm your pen friend. My name is Mark. I'm ten years old. My school is very beautiful. I am happy at school. In the morning, I do morning exercises (做早操) and dance in the playground. Then, I go to the library. There are many books in the library. We can learn a lot from books. Do you have a library? Today is a sunny day in Hainan. In the afternoon, I can swim in the swimming pool. What's the weather like in Beijing today?
Yours,
Mark
