　　Dear Sir or Madam，

　　I am writing to inform you that I wish to move into a new room next semester. I would prefer a single room， as I find the present sharing arrangement inconvenient.

　　I must explain that the reason for my dissatisfaction is my roommate’s inconsiderate behavior. For one thing， his friends are constantly visiting him; for another， he regularly holds noisy parties. In these circumstances， I find it difficult to concentrate on my studies， and I am falling behind in my assignments.

　　I am sure you will agree that the only solution is for me to move into a room of my own. Therefore， I would be grateful if you could find a single room for me， preferably not in the same building but as near to the college campus as possible.

　　Yours sincerely，

　　Li Ming
