急求一篇英语写信作文!急求一篇英语写信作文,假定你是李华,打算出国学习计算机科学,现在给在美国的老朋友David写信.1

Dear David, How are you I meant to write you for some time. You know I plan to continue my study in the US. I'm interested in computer science. So I'm writing to ask for your help. I want to know how to prepare for that as a foreign student. For example, what kind of English test is required for entrance How many courses does a student have to take each term How much do I have to pay for the courses How much do I need for food and housing Really a long list of questions. Since I know very little about American universities, it would be great if you can suggest some universities suitable for me. I'm looking forward to your reply. Thank you very much. Yours, Li Hua
