听力原文：M: Sarah, you work in the admissions office, don't you？
W: Yes, I'm...I've been here left years as an assistant director.
M: Really？ What does that involve？
W: Well, I'm in charge of all the admissions of postgraduate students in the university.
M: Only postgraduates？
W: Yes, postgraduates only. I have nothing at all to do with undergraduates.
M: Do you find that you get particular...sort of...different national groups？ I mean, do you get large numbers from Latin America or...
W: Yes. Well, of all the students enrolled last year, neatly half were from overseas. They were from African countries, the Far East, the Middle East, and Latin America.
M: Em. But have you been doing just that for the last 10 years, or, have you done other things？
W: Well, I've been doing the same job. Er, before that, I was secretary of the medical school at Birmingham; and further back, I worked in the local government.
M: Oh, I see.
W: So I've done different types of things.
M: Yes, indeed. How do you imagine your job might develop in the future？ Can you imagine shifting into a different kind of responsibility or doing something...
W: Oh, yeah, from October 1, I'll be doing an entirely different job. There's going to be more committee work. I mean, more policy work, and less dealing with students, unfortunately...I'll miss my contact with students.
