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 that 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 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 get a room of 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.
Best wishes.
Yours sincerely，
Li Ming
