Dear Mr. Ye,
I am guessing from your name that you are of Asian extraction. Therefore, it is my judgment that number four would be the most appropriate topic. However, topics 1 to 3 are okay also. I would avoid topic number five because it is a bit mundane and might tend to bore the professor, a deadly factor no matter how objective the professor tries to be. I have a great deal of experience in writing academic papers and also considerable knowledge in the area of culture and psychology, and have written a great many papers in business at MBA level on decent other topics. My usual blurb follows please take a good look at the samples and resume which I will attach.
I am American/Canadian and a native speaker of English. I have extensive experience in every kind of writing, especially academic writing, technical, informational, and entertainment. I do all my own writing, unlike some jobbers who artificially inflate their stats, and I have personally written an average of 500,000 words per year for the past 15 years, including hundreds of academic papers on a huge array of subjects and domains. Much of my work has been on business. I teach academic, fiction, and creative non-fiction writing part time. I have taught academic and business writing at MBA level. I hate the politics in education, so I freelance, working both for individuals and corporations. (I even do some work for other professors.) I do not work cheaply, but I work fast and my deliverables are always excellent. I am A+ and CNE certified and have several degrees plus published work. It is a long story why I must work, but I would write every day even if I had lots of money. It is who I am. Please Google my name to see some samples of my work. (Skip over the marketing guru sites who are pushing social networking.) I will attach my resume for your information.
Thank you, Karena
