【正确答案】
C
【答案解析】[听力原文] W: Hi, Larry, are you waiting to see Professor Jameson, too? M: Yeah, since I got one of the five highest grades in her managerial economics class, she asked me if I'd be interested in working as her assistant next semester. I'm here now for my interview. W: Oh. I know all about that job. I did it two years ago. M: Really? Did you like it? W: I think it was the best I've had at school. It paid eight dollars an hour, which was three dollars an hour more than I got working at the school post office the year before. M: That is attractive. What did you do? W: I was in charge of grading all the problem sets that were assigned as homework. M: I think I'd enjoy doing that sort of work. It would be very good experience for anyone thinking about becoming a teacher. W: Absolutely. You also learn how to use the computer data base, because the records are kept on it. And building up your computer skills is a good preparation for lots of jobs. M: The job sounds great, but I'm a little worried about how much time it might take. W: It's pretty reasonable. It never took me more than five hours a week to do all the grading and then another thirty to forty minutes to record the grades on the computer. M: That sounds manageable. I guess you can do the work when it fits into your own schedule, too, can't you? W: Oh, yea]a, you can do the grading in your room or in the library. You just need to get each set back for the next class, but that means you always have at least two days and sometimes four. M: Sounds great. W: Good luck with your interview. Why was the woman able to give Larry so much information about the job? 选项B、C、D都涉及到“她”的工作，听音时应留意。女士在第二个话轮就说到：“我了解那个工作，我两年前做过。”因此选C。女士相应的话语内容存在因果关系，I know all about that job. (As) I did it two years ago. 其实这也是一种特殊的语义点，话语内容虽然简单，但是逻辑关系很严密。
