Dear Sir,
How are you? As 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 share a room with others. My roommate often held parties at night, made much noise. Besides, his friends are always visiting him, that disturbs 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 get a room of my own, one not in the same building and as near to the school campus as possible. I would be gratefully if you could do me the favor.
Best wishes.
　　                                                        Yours sincerely,
Li Minga-an
