【答案解析】[听力原文] 15-17
W: I like that picture you put up on the wall yesterday.
M: Oh, thank you. It's a photograph that I took on my vacation last year.
W: You took it yourself? I didn't know you were a photographer.
M: Oh, yes, I've been taking pictures for years.
W: It sounds interesting. Do you have any more of your pictures here? And may I see them?
M: Yes, certainly. Some of them are faces, just faces of people whom I see when I'm walking around.
W: Do you let them know that you're taking pictures of them?
M: I try not to. I don't like pictures of people who set themselves for the camera. I like people who are going about their business without knowing the camera's there.
W: I suppose you need a lot of equipment. How many cameras do you have?
M: Well, I have a dozen of them, but I use two of them more than the others.
