A. 该土层的桩侧阻力为零
B. 该土层液化后再固结,对桩侧产生负摩阻力

听力原文:W: Hi, Larry, are you waiting to see Prof. Gilmore, too?
M: Yah, since I got one of the five highest grades in her 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, yes. 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 a good salary. What did you do?
W: I was in charge of grading all the problem sets that were assigned as homework. I never had trouble doing it, and of course, Prof. Gilmore was always available to help me if I had any questions.
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.
Questions 23 to 25 are based on the conversation you have just heard.
