建议信范文一： Dear John, You asked for advice concerning whether you should study history or computer science at university. I will try making some suggestions. University is preparation for your career. You should consider studying a subject which will best equip you to earn a living. Computer science offers more job opportunities than history. We are now in a high-tech age. For the foreseeable future, it would be necessary for everyone to be equipped with computer skills merely to earn a living! Of course, you don't have to devote all your time at university to studying computers and nothing else. I would recommend that you continue reading of history in your spare time. That way, you will find that your leisure hours are enriched while you prepare yourself for a worthwhile career in computer science. Whatever you decide to do, good luck with you studies! Yours sincerely, Li Ming范文二：Dear Helen,What a surprise it is that you are going to take this June's CET?6 since you are only a freshman in Fudan University! Anyway, your courage and efforts are worth praise.To get fully prepared for the test, I think, you need to first enlarge your vocabulary, which is the basis of all parts. Second, you need more exercises, especially exercises of reading comprehension, in order to improve your test skills. Then you should practise writing constantly. You can e?mail your compositions to me and I will correct them for you in time. In a word, every effort is rewarding. I am looking forward to your success.Best wishes.Yours,Mary
