Dear Sir,

How are you? I’m a exchange student. I am writing to tell you I would prefer to move into a single room in next term, as I find it inconvenient to sharing a room with others. My roommate often held parties at night, that makes much noise.Besides, his friends are always visiting him, which disturb me a lot.So I hope to draw your attentions to this problem.If you think in my position, I am sure he will agree that the only solution for me is to get a room my own, one not in the same building but as near to the school campus as possible.I would be gratefully if you could do me the favor.

Yours sincerely,

Li Hua
