贺信高分范文
Dear Li Ming,
Congratulate you on your being admitted to ** University. You know it is one of the most popular and competitive universities in our country. You must be very proud.
But then, university life is quite different from life in high school. It is more challenging both in your academic achievement and in interpersonal relationships. Also, it provides you with the chance to experience the kind of real life that you will face right after graduation. So make good use of the next four years; then you will be an excellent job applicant and an agreeable colleague.
If you have any questions about college life, write to me as soon as possible.
Yours truly,
Zhang Wei
贺信参考译文
亲爱的李明：
祝贺你被录取到** 大学。你知道，这是我们国家最受欢迎也最有竞争力的大学之一。你一定感到非常自豪吧。
但是，大学生活与高中生活有很大的不同。无论从学术成就还是从人际关系来说，大学生活都更具挑战性。此外，它给你提供了一个体验真正的生活的机会，而这样的生活是你在毕业之后马上就将面对的。所以好好利用未来四年吧，然后你就会成为一个优秀的求职者和一个讨人喜欢的同事。
如果你有任何关于大学生活的问题，尽快给我写信吧。
此致
敬礼!
