听力原文:W: George, as a university student, you've been here for almost a year. Do you miss your home cooking a lot? Or are you getting used to our English food? M: Oh there are quite a lot of dishes I miss very much indeed. You see in my country we have a much greater variety of dishes, but I must say English food is much better than I thought it was going to be. W: Really, what are your favorite English dishes? M: Well, first of all I think the quality of your food is excellent. Your dairy products are so fresh and your meat is usually so tender. For example, the strawberry yoghurt and pork rib chop. And there is so much to choose from in the shops. W: Yes, but what English dishes do you particularly like? Or don't you like any of them? M: Well, I'm a little tired of your fishing chips, and roast beef and Yorkshire pudding is only good when properly cooked at home. I don't like the way you cook your vegetables, either, and... W: So you don't really like any of our food, do you? M: Oh, no. I didn't say that. W: Well. I'm very fond of the steak and kidney pudding you make. And I like your apple pies... you know, all the homemade staff. M: It's very nice of you to say so! W: And I think your cooked breakfasts are simply marvelous. Nothing like them where I come from.
