Now you'll hear the two long concersations.
Conversation One
M: You like living in the city, don't you?
W: Oh, I love it. It's so convenient. I can take the bus to work, or the subway, or the taxi. And there is so much to do.
M: I know what you mean. [20]I'd like to live in the city, but to live in the suburbs is better for children.
W: Well, there are a lot of good things about suburban living. But, as a working woman, I think a city has all the conveniences-including the best food and fastest news.
M: [20]But there are more trees, grass and fresh air in the suburbs.
W: Yeah, but living in a city, it's convenient to go everywhere. There are lots of movie houses, theaters and so on. You can take them to the suburbs on the weekends.
M: Yeah, children are the right age. There are lots of things for them here.
W: You are right. They are at the library in Brooklyn. And they come back home for lunch, then go uptown to the Museum of Natural History. [21]There is so much for young people to see and do.
M: [21]Not just for young people. What about me? I've never been to the Museum of Natural History.
W: Neither have I. When I was a child, I used to go to the Museum of Art.
M: I've been there several times. Twice with children.
W: [22]Well, I have an idea. Next weekend, we go to the Museum of Natural History.
M: Ok, that's really a very nice idea.
