三。投诉信参考范文：
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. He/She has parties in the room and sometimes borrows your things without asking you。
Write a letter to the Accommodation Officer at the college and:
1) ask for a new room next term,
2) you would prefer a single room,
3) explain your reasons。
Don’t sign your own name at the end of your letter, using“Li Ming”instead。
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 difficulty/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
