【答案解析】[参考范文]
Dear Li Ming,
I am writing to congratulate you for your wonderful success in your college entrance examination.
I heard you have achieved overwhelming and remarkable scores in the college entrance exam. In order for you to adapt yourself to the university life, you are advised to get prepared physically and intellectually. Firstly, you need to build a strong body for the future academic pursuit, so you can take some exercise during the breaks. Secondly, since the study in university is more demanding than in your secondary school, you are highly suggested to find some introductory books from the library so as to have a good idea of the specialty you are going to take in your college life. Given your sound ability, you are sure to have a successful college life.
I hope you can keep studying. It will be never too old to learn. May you have an amazing time in college!
Best wishes.
