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 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,
