【答案解析】Dear Sir,
I am a new student who has been living here for about two months. I am writing to report the problems with the dorm management.
The first thing I have to say is that security of the dorms should be improved. Strangers can go in and out freely without any inquiry or check. Thievery Occurs from time to time．Secondly, the heating system is frequently out of order without being repaired in time. As a result, many of my roommates have caught cold.
I sincerely hope that the people in charge of the dorms would take immediate actions to solve these problems.
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Yours truly,
