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 you're my guest. W: Gee, it's crowded. M: Look, one empty small table by that big picture window over there. Let's go and get it. 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 and that's a pretty picture, too. W: Is this the only type place for lunch? M: There are some lunch counters, but they serve only a few specialties. W: Why can't you eat 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 to run back and forth from home to school or office, because the 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. If all the food tastes as good as this, I don't miss our own food too much. I like American food! M: I'm glad you enjoy it. Are you done? W: 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)
