"You really have to let the admissions committee know what it is about this program in particular that interests you."
-The Woodrow Wilson School of Public and International Affairs, Princeton University
"It helps for the student to have done some research on the university being applied to. It is easy to differentiate an applicant who really wants to come here because of our special resources from someone whose knowledge of the program comes simply by way of the brochure we send to all interested applicants."
-Graduate English Department, UCLA
F、Writing Ability （写作能力）
Again, the importance of writing ability varies according to different programs. A great flair for language will not get you admitted into a biochemistry program, but it's still essential to demonstrate strong written communication skills. On the other hand, you should also keep in mind that a well-written essay makes its points clearly and forcefully, so your content benefits as well.
Good writing means more than the ability to construct grammatical sentences. You also must create a coherent structure and ensure proper flow as the piece progresses. Because the process of developing ideas and putting them down on paper is so intimate and personal, all writers end up needing editors to assess the effectiveness of their product. You should consult people whose writing you respect for advice or even more hands-on help.
