Conversation One
M: Hi, Mary. Do you want to start writing a lab report after we finish this experiment?
W: I can't. In fact I need to finish early because [19]I'm going over to the psychology department to talk to Professor Smith about a job opening.
M: You mean a job on campus?
W: Yeah. And it sounds pretty interesting. It involves helping with your study on learning style. You know, about how some people learn best by sight, while others learn best by hearing or touch.
M: Yeah. I know that's an area of expertise.
W: Right. Anyway for her study she's taking some high school students who aren't doing very well in their classes and testing them to find out what their learning styles are. Then tutors, people like me, will work with them presenting material to them in their particular learning style.
M: Hey. That is interesting. Now will you mostly do the testing or the tutoring?
W: Both I hope. I want to be involved from start to finish.
M: Are you getting paid for this?
W: I'm sure we'll get something though, probably not much. Anyway it doesn't matter to me. [20]I just want to have some hands-on experience.
M: Yeah. And it'll be nice to help those high school students too.
W: That's what I thought when I saw the ad. You know you could do it too. You don't have to be in her classes to work on the study.
M: Really?
W: Yes.
M: That's perfect for me.
W: Then come along. [21]We will save the lab report for later. But we'd better make sure we do a good job on our experiment first.
M: Yeah. First thing's first.

答案解析：
19. What are the speakers mainly discussing?
[D]解析：主旨大意题。女士在第一轮对话中就说：“我想到心理系和史密斯教授谈谈一个工作机会”，直接进入话题。故D正确。
20. Why is the woman interested in working with Professor Smith?
[B]解析：女士说：“我想获得一些实际动手的经验。”故B为答案。选项内容都是She想做某事，尤其A、B、D都是阐述某种愿望，故题目可能是问原因。答案中的practical是原文hands-on的同义替换。听到什么选什么。
21. What will the speakers probably do next?
[D]解析：女士说“我们还是把实验报告留到以后做吧。不过首先我们最好要保证做好我们的实验。”对话中的“do a good job on our experiment”和D相吻合，故D正确。由动词选项知，本题为对话“尾巴题”，一般问对话双方下一步的行动，结尾处的内容是答题要点。
