听力原文：M: Do you want to go to the cinema with us on Saturday?W: Thanks, but I have to study for my research project. I'm taking that same anthropology course you took with Professor Gray.M: The one on ethnographic interviewing? Oh, good! I'm sure you'll get a lot out of it.W: I have to admit the word 'ethnography' seared me a little at first. It seems so technical. But then when she explained that it's what anthropologists do, you know, how they investigate and record aspects of a culture, it didn't seem so intimidating!M: Yeah, it's a part of the field work anthropologists conduct and it's good to start doing that now before you become a graduate student and have to conduct large projects yourself. Who are you going to interview?W: You know the publishing office where I used to work? Vivian, the woman I worked for, has been a manager there for over 30 years and seen a lot of changes in the industry. I thought I'd start out by interviewing her about how the people in the office interact with each other and with outside clients.M: The best part of that course is that it shows you that ethnographic research can also be done on a familiar ground.W: Yeah. I got the idea for my project from reading Robert Marshal's study of office life and I realized I already had some background in that. So far, I'm really enjoying this course.(20)A．Which major the woman will be choosing.B．An anthropology course the woman is taking.C．How to find a job in publishing.D．Which anthropology professors the man recommends. 点击查看答案
