【答案解析】[听力原文]
   M: What are you going to have?
   W: I have no idea. Could you help me with the menu?
   M: Yes, sure. These are starters, and these are main courses and these are desserts. See?
   W: What's the alternative?
   M: The alternative is to order a complete dinner. For a set price you get your choice of soup or juice, one dish with potato and vegetable, salad, bread and butter and sometimes coffee and sometimes dessert.
   W: And you pay the price listed next to the main course?
   M: Right. Like the roast beef dinner is $7.85—plus tax and tip, of course.
   W: It's all looks pretty expensive to me.
   M: It's not. This is only a bit more expensive than McDonald's. So enjoy yourself. We're celebrating, remember?
   W: You're kind.
   M: Friends are friends. I cannot get promoted often. Are you ready to order?
   W: Ah, can you tell me what Hot Fudge Sundae is?
   M: That's a dessert. It's an English specialty. It's a kind of ice cream with a hot sticky sauce over the top—very sweet and fattening!
   W: I don't really like the sound of that. How come here is English food? I thought we agreed to eat American food.
   M: Our country is made up of people from all over the world, so besides collected words and phrases from every language, we've also absorbed recipes. We even have a lot of Chinese restaurants now.
   W: Which is better, French or Chinese cuisine?
   M: I'd say it's a toss-up. I love them both.
   W: I didn't know you were so fond of foreign foods. When my boss promotes me, I will take you to a French restaurant near my company. The food there is delicious.
   M: Oh, we will have a second dinner soon.
