听力原文：(M =Jack; W = Anne)
M: Hey, Anne, long time no see !
W: Yeah, what are you doing？
M: Oh, just hanging around my suite.
W: Oh, you got a suite this year？ I remember last year you were in a triple. I mean, those rooms were really supposed to be for two people, but they stuffed of you in them.
M: Right. That' s why I got to bid first for my room this year. And now me and five other guys are in a suite.
W: So it' s three rooms for two people each？
M: Right. And how about you？ Where are you living this year？
W: I' m out in the Hillside Community. I really like it there. It' s a little further away from the Academic buildings, but it' s nice and quiet. You know, I' m net much of a party goer.
M: I know. Last year our crazy floor used to keep you up all night! De you remember when the RA caught me with beer in my room？ I had to do 15 hours building service!
W: That RA was so strict! In Hillside, since it' s mostly an older community, there are no regulations about alcohol. However, Sunday through Thursday, and Friday and Saturday after 1 a.m. are all "quiet hours".
M: Is it more expensive to live up there？ I know the apartments are really nice.
W: Yeah, a lot more. It's about $2,000 a semester.
M: Whoa. My room is just $1,400 for a year per person.
