【正确答案】范文：
Dear Sir,
I'm a student from Tsinghua University. I want to rent an apartment near my school. The apartment should have one or two bedrooms with a bathroom. Besides, I hope it costs no more than six hundred yuan per month. I want to move in at the beginning of next month. If you have any information, please call me at 62785001.
Thank you.
Yours sincerely,
Ginger Breadman
