听力原文：W: Congratulations on your new job, Chris! Last year you wanted to get out of university! M: I know, but that was last year. To tell you the truth, I' m not so sure I like working. Now, it's just work, work, work. I work hard all day, every day. Now, I have money, a nice apartment and a car. But I don't have any time to enjoy it all. W: Oh, come on. Don't complain. You' re making a good salary now. Last year, you didn' t make anything. It can't be all that bad. So tell me, what do you miss about university? M: I used to go to parties, I stayed up late talking with friends. But now I' m tired at work. I can't do that. I have to be serious about things. You don't understand me because you are still in school. What did the man want last year?A.
University
