Doug and Liz正开车去超市买菜，可Doug忽然觉得饿了，想顺道先去快餐店买个汉堡吃。
Professor: Winnie, do you ever get hungry when you go shopping?
Doug: Hey Liz, I'm really hungry. Let's stop and eat something.
Liz: Alright, where do you want to eat?
Doug: There is a McDonalds nearby.
Liz: Fast food is so unhealthy. But if you are really hungry, we can go through the drive-through.
Doug: No, let's go inside. I don't want to spill my drink in the car.
Professor: So Winnie, did you hear where Doug wants to eat?
Professor: Exactly! Why doesn't Doug want to use the drive-through?
Professor: That's true. I guess there are two ways eating fast food can kill you.
Cashier: Welcome to McDonalds! May I take your order?
Doug: Yes, I'd like two hamburgers, a large Coke and a large fries.
Cashier: Do you want anything, ma'am?
Liz: No thanks, I'm on a diet.
Cashier: For here or to go?
Doug: For here.
Cashier: Alright, that will be 11 dollars and 50 cents.
Liz 说，she is on a diet, 正在节食，所以不吃这些高热量的快餐。Doug 真应该向 Liz 学学。
Professor: Yes, fast food has a lot of fat in it. But Winnie, does Doug want the food "for here" or "to go"?
Doug 说for here, 也就是在餐厅里吃。如果说 "to go"，就是打包带走的意思。
Professor: Yes. When you take food home from a restaurant, you can also say the food is for "take out." Now Doug and Liz are eating their food. Let's listen.
Doug: Do you want to eat my tomato? I don't like them. The only topping I like is ketchup.
Liz: Sure, I love tomatoes. They're a healthy food.
Doug: That's true. Are you sure you don't want anything?
Liz: Well I know the French fries are very unhealthy, but they look so good.
Doug: Come on Liz, try one. It won't kill you.
Liz: Well alright, I'll have just one.
Doug: Great! I'm going to get a refill of soda.
看来， Liz 的决心动摇了。虽然她一直在说快餐多没营养，可是一看到Doug的薯条，也忍不住要吃上一根。
Professor: That's right. And did you hear what topping Doug likes, and which one he doesn't like?
Doug 说, 在汉堡的所有佐料中，他只喜欢ketchup--番茄酱, 还说他不爱吃番茄。真奇怪，番茄酱不就是番茄做的嘛？
Professor: That's right. What does Doug say he is going to do at the end?
他说他要去refill他的饮料. Professor, refill, r-e-f-i-l-l, refill 就是续杯的意思吧？
Professor: Correct. When you go to a restaurant, you can ask the waiter, "Do you have free refills?"
Professor: Now let's see what Doug says when he returns to the table.
Doug: Liz, where are all my fries? Did you eat them all?
Liz: I'm sorry, Doug. They were just so good! Once I started eating them, I couldn't stop.
Doug: Don't worry Liz. If I'm going to get really fat, you should get really fat too! We will look really cute together.
Liz: Wow, that is a really scary thought. I need to exercise right now!
啊？ Liz 趁Doug不在，居然把他的薯条都吃了！不过，她显然不想和Doug一起变成胖子，所以说要马上去健身。不过首先，希望他们在超市能买些健康食品!
Professor: Well listen next time to find out!
