【答案解析】[听力原文]
   M: Good afternoon, ma'am. I'm Mr. Smith. I called you a little while ago about the apartment for rent.
   W: Oh, right, Mr. Smith. Come in. Let me show you the place. The two rooms are upstairs. Come with me.
   M: You have a very nice house.
   W: Thanks. Here we are. Both are simply furnished with a bed, a desk and a cupboard.
   M: This is not bad. How's the hot water? That's very important. I'm asking because where I live now keeps running out of hot water. I can't tell you how many cold showers I've had to take. In fact, I had to take one just this morning. I can't stand taking cold showers any more.
   W: Don't worry. You can shower to your heart's content in here.
   M: How much is the rent?
   W: Well, how about $250 a month for each room? That includes water, electricity and gas.
   M: Well, that sounds quite reasonable. Did you say quite a few people are waiting for these two rooms?
   W: Right. But you have no children. I'd like to put you up higher on the list.
   M: Well, thank you very much. I'll consult with my wife and contact you as soon as we make up our minds. It's really very nice talking with you.
   W: Thank you. I'm glad you like the rooms.
   What are the two speakers talking about?
