【经典范文】 Dear Tom, I have missed you very much. How about your study and life in China? I should tell you that I have something to be helped by you. In July, I will take part in an English speech contest for middle school students in Beijing in summer vacation. I want to make a speech about American scientist Thomas Edison.

But I don't know about him deeply. Could you tell me some background about him, especially how hard he studied science? Please tell me more about his spirit of devoting himself to_science and_his stories about_the innovation_in science. I wish I could become a scientist like Thomas Edison to invent many new things for the world. And please tell me how to use the American motto, which can make my speech more vivid. I will visit you after the speech contest. Thanks a lot! Faithfully yours! Li Hua
