【答案解析】[解析] 19-22
M: Hello, This is Peter Smith's speaking.
W: Hello, Peter, Betty's speaking. I'm calling about the open-door concert in London. Will it still be held this Sunday, as is scheduled? It's been so cold that I haven't been outside for a week. I do hate the Cold.
M: Yes, it's best to stay indoors in such beastly weather. But I'm afraid I have no idea about the oncoming concert. You noticed our new neighbours who have arrived at number thirty-five though, surely. Perhaps they knew something.
W: Well, I called on them yesterday. They seemed such nice people at first—but now I'm not so sure.
M: Really? Why?
W: Well, they are from London, and they think it's the only place in the world worth talking about. The wife made some very catty remarks about this area.
M: Londoners always think they' re better than other people, but I always find them less cultured. What does she look like?
W: Quite young and pretty, but she does wear a lot of makeup, and she certainly dyes her hair. Perhaps she isn't as young as she looks.
M: Anyway I don't want to mix with people like that. Because I knew they would be snobs when I saw that huge car. Surely they don't need such a big one.
W: No... still, my husband says it's four years old and it probably cost less than ours second-hand; and ours is certainly as fast as theirs. Besides, it uses so much petrol. You can hardly afford to run it.
