假設你是一名大四學生，即將畢業離校，請你根據四年的大學生活的經歷給大一新生寫一封忠告信：

　　1. 作簡單介紹

　　2. 大一新生如何適應大學生活

　　3. 強調學習英語的重要性

　　【范文】

　　I, the undersigned, am a senior in the Computer Science Department of Peking University. I would like to say a few words to you, which I hope would be helpful to you.

　　To begin with, the change of ideas is of most importance for freshmen to adapt themselves to campus life. During the middle school days, we usually depend upon our teachers at school and parents at home. However, the life and study on university campus features independence, which is essential to our psychological development. In my view, we had better always bear in mind the idea of independence.

　　Whats more, English learning is a must. On one hand, without CET 4 certificate, we can not get our degree when we graduate from university. On the other hand, when we hunt for job, English level is a deciding factor. Therefore, I do hope that all of you will have a good understanding of the necessity of learning English well.

　　Good Luck to you!
