Good afternoon.I'mCelia Kim，housing director here at the university．[16]I'm  visiting all the dormitories this week to inform students about check-out procedures．I know you have a lot on your minds with finals coming up，but there are a few things you need to be aware of as you prepare to leave for vacation．This dormitory will be closed during the summer months and will reopen on September 1st．You must vacate your room by June 3rd．Even if you’re registered for classes during the summer，you must leave this dorm by June 3rd．If this poses a problem for you，you should contact my office as soon as possible．You should remember to rum in your room key before you leave．Failure to return your key call result in a 20-dollar fine．[17]You must also make sure that all of your personal property has been cleared out of your room．[18]I'm be passing out a form for you to fill
out concerning the condition of your room．You should report on the form any damage to your room which has occurred over the last year，such as holes in the room’s walls,doors ,windows or cabinets．That way，our summer maintenance crew will know where to make repairs before the next school year starts．If you have any
questions during the next few days，please ask your resident advisors or call my office．Now please take one of the forms as they are passed around．
What does the speaker mainly discuss?
【解题思路】四项均为名词短语，相互之间关联度不高，且该题目为此段短文的第一题，因此很可能考查短文的主旨。
【解析】讲话者在开头就进行了自我介绍，表明自己是 “housing director here at the university(大学的住宿主管.，其讲话内容也围绕学生宿舍在暑期的各项管理规定展开，可见该短文的主旨是暑期前的各项退宿手续，故选D。check-out意为“离开房间；退房结账”，其反义短语为“check-in(办理入住；登记，报到.”。
