A letter to my friend
Dearxiaofang                                    2008-05-7:                                           
    I am grade to receiving your letter .in the letter I got to know you were accepted into zhejiang normal university which famous across the nation. Congratulations.
    There are a wealth of differences between college life and middle school life. At zhe first place, classrooms are unfixed; every course has a special classroom. Secondly, in addition to required courses, you could take a grate variety of optional course to expend you sight. Take myself as an example; I take a keen interest in history. So I choose “china history”, “world history” and so on. At last, during these four years you will take majority time in room, so you should get with your roommates friendly.
    In my eyes, you could not relax yourself too much and maintain your advantage. The most important is pass CET-4 as soon as possible.
  Best wishes.
                                                                Yours

亲爱的小芳：
    我很高兴收到你的来信。在信中我得知你被浙江师范大学录取了，这是一所全国有名的大学。祝贺你。
    大学生活和中学生活有很多的不同点。首先，教室是流动的，每一门课有一个专门的教室。第二，除了必修课，你还可以选各种各样的选修课来扩展你的眼界，就拿我来说吧，我对历史有很大的兴趣，我就选了中国历史和世界历史等等。最后，在这4年里，你大部分的时间会在寝室，所以要和你的室友友好相处。
    在我看来，你不能太放松自己，要保持你的优势，最重要的是尽快过四级。
    祝贺你。
