Dear professor Moss:

　　I am Sandy Lee, an undergraduate student of the department of Electrical and Computer Engineering.

　　At the beginning of this semester, I registered one of your courses, African Literature and Culture. It is a two-hour course held on every Thursday afternoon.

　　Yesterday, I received a notice from my department that a major course, Computer Principle, would be changed to Thursday afternoon. This major course conspicuously influences my credits and it is every important to me.

　　Unfortunately, I can not study your course this semester. Because of your reputation and my enthusiasm in literature, I hope I could study this course in next semester.

　　I also heard that another course of yours, China Literature, is held every Friday afternoon.

　　If the registration of this course hasn’t closed yet, I will be so glad to participate in your class. Sorry to bother you, your help will be greatly appreciated.

　　Sincerely yours,

　　Sandy Lee
