【正确答案】 D

【答案解析】[听力原文]18-21 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 the experiment early because I'm going over to the Psychology Department to talk to Professor Elizabeth about a job vacancy. 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. Any way 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: Mm, that is interesting. Now will you mostly do the testing or the tutoring? And are you getting paid for this? W: Both I hope. I want to be involved from start to finish. I'm sure we'll get something, though, probably not much. Anyway it doesn't matter. To me, I just want to have some experience. M: Yeah. And it'll be nice to help those high school students too. Do you have any idea what the schedule is like? It sounds great. 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. From late afternoon to evening for tutoring I think. After all the kids are in regular classes until three thirty. If you like, come along. We will save the lab report for later. But we'd better make sure we do a good job on our experiment first.
