　　Now you’ll hear two long conversations。

　　Conversation One

　　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’s, my roommate. I took this picture right after we had arrived at the school this fall. We had just met, in fact. And this was our room of the dormitory while we were unpacking all our things. What a mess!

　　W:You certainly had a lot of boxes. How did you ever find room for everything?

　　M: In the beginning we thought we’d never get all arranged but now we are 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 and makes too much noise. Then I get angry. Sometimes I leave my books 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。

　　Questions 19 to 22 are based on the conversation you have just heard。

　　19.Where is this conversation most probably taking place?
