【正确答案】Dear Mr. Wang, 　　Thank you for the job opportunity you have offered me, but after two-month work as an editor for your magazine, I find that the job is not quite suitable to me. So I have to give it up. 　　This is mainly because my major at university is computer science. Although my dream is to be an editor, I find it hard to cope with my present job without much knowledge about fashions. What I have learned can be of little help to my work. I'd like to find something closely related to my major. 　　I'm awfully sorry to make this decision. A more qualified editor, I believe, will make a great contribution to your magazine. 　　Thank you for your time and attention.　 　　　　　　　　　　　　　　　　　　　　Yours respectfully, Li Ming
