Dear Kate,
You are in New York, but I am in Beijing now. China is a great country  and Beijing is a big city in China. It's very beautiful. I like it very much. There are twenty-four girls and nineteen boys in our class. One of the boys is from England. His name is Bob. He likes swimming. Sue and I come from America.
Sue likes playing the piano, but I like playing volleyball. I have many Chinese friends here now. They teach me Chinese and I teach them English. Chinese is not easy, but I like it.
Yours
Nick
