听力原文：M: You've worked in a university before, haven't you? W: Yes, in Britain. M: What, um, how do students go about getting jobs when they graduate? W: Well, most universities have a Careers Advice Service. I used to know the people in the Careers Service in Newcastle University and they, in fact, seem fairly successful in finding jobs for students. They are able to get jobs for 30-40% of new graduates. M: That seems a fairly low percentage. W: Um…well…it's not if you consider the various other options which people take up. For example, there are a fair number of people, who go into further study, who carry straight on into master's degrees, either at the same university or another university. Then there is a second group of people who decide not to take a career job immediately after university. Instead, they decide to take time off, maybe see the world, and…and…well, there is a third group who can't actually get the jobs they want immediately, and who may take something else while they wait for a job they really want. So when I say 30-40% find jobs through the Careers Service, that doesn't mean that only that number find jobs. A lot of other people find jobs through the newspaper. M: So it is quite high really, yes? W: Oh, I think so, relatively, yes. And quite a lot of other people, of course, look in newspapers and the particular journals or magazines which advertise jobs in the fields they're interested in. What is the percentage of college graduates getting jobs through university Careers Service?
