听力原文：M: Hi, Mary. Do you want to start writing a lab report after we finish this exper

iment？ W: I cant. In fact I need to finish early because Im 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 her 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 thats her area of expertise. W: Right. Anyway for her study shes taking some high school students who arent 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 we hope. I want to be involved from start to finish. M: Are you getting paid for this？ W: Im sure well get something, though probably not much. Anyway, it doesnt matter to me, I just want to have some hands-on experience. M: Yeah. And itll be nice to help those high school students, too. W: Thats what I thought when I saw the ad. You know, you could do it, too. You dont have to be in her classes to work on the study. M: Really？ Do you have any idea what the schedule is like？ W: Late afternoon, then evening for tutoring I think. After all, the kids are in regular classes until three thirty. M: Actually thats perfect for me. W: Then come along. We will save the lab report for later. But wed better make sure we do a good job on our experiment first. M: Yeah. First things first.
