听力原文：M: Let's sit here and order some coffee while I'll show you some pictures. W: Good idea. But I'd prefer tea, please. M: This is Ted, my roommate. We live in the dormitory. W: Is this your room? You certainly have a lot of books. How did you ever manage to put them in such a good order? M: Ted did this for me. He is a neat person. W: Do you like living in the dormitory? M: Yes. Ted is a very good guy. Sometimes I leave my books and clothes lying around and he gets angry. Sometimes he turns his radio up too loud and makes much noise, then I get angry. But on the whole we can get well along. W: Where did you take this picture? M: That's a picture of us taken when we went to the beach during vacation. W: You look so smart. This is a lovely puppy. M: That's my dog Allen. He is now with my parents. Where does this conversation most probably take place?
