【正确答案】[参考范文]
Dear Ms. Thompson,
I have applied for admission to Chicago University. As I have no relatives in the United States and I have no enough money for the tuition, I must find a financial guarantor. As you know, in applying for a student visa, an affidavit to support must be submitted from an individual who will assure this opportunity. It plays an important role for my chance to enter the university. Could you do me a favor to be-my financial guarantor? If I really have the chance of coming to the U. S. , I will undertake part - time employment (o cover all the living expenses.
Please write to me soon.
Yours sincerely,
Wang Ling
