M: Hi, I’m from the Students’ Union. We’re doing a survey of students’ eating habits. Is it all right if I ask you a few questions?
W: Will it take long?
M: No, not really. Five minutes maybe? There aren’t all that many questions.
W: And what’s it for exactly?
M: Well, we wanted to get an idea of the sort of things students eat on a regular basis, and [6] find out how aware people are about diet and nutrition. The idea is to produce an information leaflet about healthy eating.
W: Yes, I suppose something like that would be quite useful, a leaflet I mean, especially for new students. Anyway, what do you want to know, exactly?
M: OK, first question. What would you say your favorite food is?
W: That’s easy. A burger and chips. Lots of chips! I must say I like a nice Chinese meal as well, and maybe spaghetti once in a while... But no, [7] the best has got to be a burger.
M: OK, and what’s your least favorite food?
W: Let me think. I’ve never been that keen on cauliflower, or fish—the smell puts me off. But no, the thing I really can’t stand is salad. Rabbit food, I call it. I know lettuce and things are supposed to be healthy and all that, but it’s just not a real meal, is it?
M: Mmm. You’re getting into some bad habits there, you know. Anyway, moving on... Let’s take a typical day. How many meals do you have? I mean proper sit-down meals, not snacks.
W: Well, [8] I nearly always oversleep, which means I generally skip breakfast altogether. And then I’d probably just have a bar of chocolate for lunch. So in answer to your question, I don’t sit down to a proper meal till the evening.
M: OK. Typical student. I suppose! And the next question: How many eggs would you eat in a week? One? Two?
W: Well, I don’t do much cooking as a rule, but every Sunday I make myself a nice fried breakfast as a treat. That’s sausages, bacon and two eggs. Lovely!
M: That sounds OK once a week. But [9] I wouldn’t recommend it on a regular basis. Too much fat. And how about fresh fruit? Does it figure in your diet at all?
W: Not really, well, I know it’s bad, but... I’m just not in the habit really. [10] I suppose I might eat an apple once in a blue moon.
M: Pity. But I suppose it’s better than nothing! And would you say you had a sweet tooth.
W: I guest so. Well, most people have, haven’t they? Me, I can’t resist a bar of chocolate.
