听力原文：W: Excuse me, do you mind answering a few questions? M: No. W: Firstly, do you ever cat fast food? M: Yes, I do. W: What kind of fast food do you normally eat? M: Oh, you know, burgers, sandwiches, well sometimes like a pizza. W: Oh, right. And how often do you eat fast food? Every day, more than once a week or less than once a week? M: Well, Monday to Friday when I'm working, but not usually at the weekends. W: And what time of day do you eat fast food? M: Well, at work as I said, you know at lunchtime I go out and get a burger or a sandwich. Sometimes, if I'm going out and I don't have time to cook in the evenings then I'll send out for a pizza. W: Oh, right. Do you only eat it as a main meal or do you snack between meals? M: No, only a main meal, you know luxurious, in the evening. W: And what do you think of fast food? Which statements do you think are true? Um, either 'It's convenient'? M: Oh, definitely. I mean, that's sort of the main reason that I eat it. W: Right. How about 'It tastes good'? M: Yeah, I mean, not as good as food like in a good restaurant, but it's not bad. W: 'It's good for you'? M: No. Sort of eating quickly and standing up it's sort of bad for you, the food itself isn't very good for you, you know there's not enough greens, you know vegetables or salad. W: How about 'It's an expensive way of eating'? What do you think of that? M: Oh, yes, it is, but you're paying for the convenience, you know the speed of it. Well, I certainly think that it's cheaper than cooking your own food. W: And what about lastly 'It creates Jitter'. Do you think that's true? M: Yes, it does. Only I always put mine in a litter bin, but unfortunately a lot of people don't, but in the packaging there is a lot of paper involved and plastic and sometimes polystyrene. (23)
