听力原文：W: Ok, this will be my treat. M: Oh, no, you don't. W: All right then, we'll go Dutch. M: Next time. This time it's my treat. W: Mine, it's nice to have lunch with such a prosperous gentleman. M: Thank you. W: Gee, it's crowded. M: Look, one empty table by that big picture window over there. Let's go and get itt W: Ah, this is a pretty spot. You can see the people passing by while you eat. M: And they can see you eat while they pass by and that's a pretty picture too. W: You not only coin a neat phrase, but turn a girl's head too. Is this the only type of place for lunch? M: There are some lunch counters, but they serve only a few specialties. W: Why can't you eat your lunch in a restaurant? M: Well, you can, but the service isn't as fast. Most people only have half an hour to one hour for lunch. The time is too short for them to eat in a restaurant or run back and forth from home to school or office, because cities are too big. W: So they eat quickly at the lunch counters? M: Right. Lunch is normally a light meal anyway. Workers must either take lunch with them or get it near the place where they work. W: What about the children? M: Kids in school take sandwiches, fruit and cookies along with them or eat in school cafeterias. W: This is delicious. I fall the food tastes as good as this I won't miss our own food too much. I like American food! M: I'm glad you enjoy it. Are you done? W: Yeah, I'm full. M: Are you sure? You can get seconds. W: I'm positively full. I have no more room. Wow, this will last me for a week. Thank you very much. M: Don't mention it. (20)
