| Dear friend: Hello, I'm your new friend. My name is Bob. I'm fifteen. I'm American. I live in New York. I am a middle school student. I'm good at maths. It's very interesting. My favourite sport is basketball. And I am not only a basketball fan but also a good player. I like pop music, my friends and I often sing pop songs together. After school I am interested in getting on-line. I have known a lot about China from the Internet. Now I'm learning Chinese. I hope I will visit your country one day. Please write to me and tell me something about your life. I'm looking forward to hearing from you. Yours, Bob | ||||||||
