You have a friend who is about to enter university, and he wants you to advise him on which subject to specialize in—history, in which he is very interested, or computer science, which offers better job prospects.
1）Give your suggestions.
2）Explain the reasons.
3）Other recommendation.
Dear Wangcai,
You have asked me for my advice concerning/regarding whether you should study history or computer science at university, and I will try to make some useful/practical/conducive suggestions/proposals/recommendations.
You must keep in mind that, above all, your university training is a preparation for your future career. There is no doubt that the field of computer science offers far wider job opportunities than history. Besides, for the foreseeable future, not only will it be necessary for everyone to be computer-literate, it will also be necessary to be equipped with computer skills merely to earn a living.
Of course, I would recommend that you keep up your reading of history in your spare time.
Yours sincerely,
Li Ming
