听力原文:W: Let's go in here and order some coffee while we look at your pictures.
M: Good idea! We'd both like coffee, please. OK, here's one of Ed, my roommate. I took this picture right after we had arrived at school this fail. We had just met, in fact, and this is our room in the dormitory while we were unpacking all of our things, What a mess!
W: You certainly bad a lot of boxes. How did you ever find room for everything?
M: In the beginning we thought we'd never get it arranged, but now we're very comfortable. Lucky for me Ed keeps his things neat.
W: Do you like living in the dormitory?
M: It's not bad. Sometimes Ed turns his radio up too loud or makes too much noise; then I get angry. Sometimes I leave my books and clothes lying around and he gets angry. But usually we get along. Here's a picture of him taken when we went to visit my family during vacation.
W: And this last One?
M: That's my dog, Spot.
