Directions：

You live in a room in college which you share with another student. You find it very difficult to work there because your roommate always has friends visiting and has parties in the room.

Write a letter to the Accommodation Officer at the college and ask for a new room next term. You would prefer a single room. Explain your reasons.

Dear Sir or Madam，

I am writing to express/air dissatisfaction/disappointment/concern regarding accommodation. I would prefer to move into a single room next semester， 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.

To solve this problem/surmount this difficulty/improve this situation/crack this hard nut， I hope to draw the attention of the authorities concerned. I am sure you will agree that the only solution for me is 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
