Dear Prof. XXX,As the semester begins, I am concerned about my course selection. I'd be very glad if you can give me some advice on which courses I should take this semester.
I have taken XXX(class name) previously. Do you think I need to further this topic and take YYY(class name)?Sincerely.
一英语的影响力
（1）从全世界来看，说英语的人数已经超过了任何语言的人数，10多个国家以英语为母语，45个国家的官方语言是英语，世界三分之一的人口（二十几亿）讲英语。比如在日本，除了他们的本国母语——日语之外，英语是他们的第二语言，很多高层次的日本人以会说英语为荣。
（2）全世界75％的电视节目是英语，四分之三的邮件是用英语书写，电脑键盘是英语键盘，任何一个会议敢号称是国际会议，其会议工作语言一定要用英语，也是联合国的正式工作语言。
二英语听力的注意事项
（1）领到试卷后应迅速浏览听力部分，尽快根据题干和选项预测可能出现的录音内容，努力寻求选项之间的差别，提高捕捉信息的准确度。
（2）听力测试的时间是预先设定的，通常为12分钟左右。因此，要培养抢记内容的能力，如人名、地名、时间、数字等。特别是对那些一时拿不准、写不出的词要学会用音标或缩写词作快速记录，以便在录音结束后为自己创造追忆的条件。
