SECTION A CONVERSATIONS
Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.
听力原文：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 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 her study on learning style.
M: Yeah. I know that's her 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: 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, I just want to get 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？ 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 that's perfect for me.
W: Then come along. We will save the lab report for later. But we'd better make sure we do a goad job on our experiment first.
M: Yeah. First things first.
Why is the woman interested in working with Professor Smith？

听力原文： Scientists have discovered evidence that a dinosaur found in Montana was a female. Scientists have never before been able to reliably determine the sex of fossilized dinosaurs. The latest discovery gives them a tool to identify at least some females. What they found was a layer of something called medullary bone inside the thighbone of a dinosaur dug up five years ago. Scientists had cut the bone into two pieces to get it into a helicopter. Medullary bone is only known in ovulating birds, it's a source of calcium that birds draw to make shells for their eggs. Writing in the journal Science, the scientific team believes the bone layer could be a way to identify other female dinosaurs but only if they died while making eggs and were then fossilized. They point out that the discovery confirms the view that modem birds are the closest living relatives of the two-legged dinosaurs.
Which is NOT correct description about Medullary bone？
