【正确答案】[范文]
Dear Paul,
Thank you for your letter, in which you asked me for my advice concerning whether you should study history or computer science at university. I am rather glad to make some useful suggestions.
You should bear in mind that your first consideration should be to study a subject which will best equip you to earn a living. There is no doubt that the field of computers offers far wider job opportunities than history does.
Of course, you don't have to dedicate all your time at university to studying computers. On the contrary, I would recommend that you keep on your reading of history in your leisure time. Therefore, you will find that your leisure hours are enriched while you prepare yourself for a worthwhile career in computers.
Yours sincerely,
LiMing
