听力原文：W: Why don't you get another job for a change? M: But I like my job. W: Look, digging gardens is not a job for a university graduate. M: But the money is not bad and there's plenty of fresh air. W: If I were yon, I'd take some kind of direction layer teaching. M: Teaching? Anything but that. It's so boring. W: Come on, you really must think of the future. M: I'll tell you what. I'd like to be a doctor. W: Well, you should think very seriously about that. It means a lot of study, and then working all sorts of hours. M: Yes, maybe. But the idea sounds interesting. W: Well, then, you ought to get more information about it as soon as possible. (20)
