【答案解析】[听力原文]
M: Hello. This is Peter Smith's speaking.
W: Hello Peter, Betty's speaking. I am calling about the open-door concert in London. Will it still be held this Sunday as is scheduled? It has 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 am afraid I have no idea about the oncoming concert. You noticed our new neighbors who have arrived at No. 35 though. Surely, perhaps they knew something.
W: Well. I called on them yesterday. They seem such nice people at first but now I am 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 it. The wife made some very catty remarks about this area.
M: Londoners always think they are always 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 make-up 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 snob when they 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 costs less than our secondhand. And ours is certainly as fast theirs. Besides, it uses so much petroleum. You can hardly afford to run it.

What has the woman done for the past week?
