Professor: Now Doug and Liz are eating their food. Let's listen.
Doug: Do you want to eat my tomato? I don't like them. ___________________________.
Liz: Sure, I love tomatoes. They're a healthy food.
Doug: That's true. Are you sure you don't want anything?
Liz: ____________________________.
Doug: Come on Liz, try one. It won't kill you.
Liz: Well alright, I'll have just one.
Doug: Great! __________________.
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. _________________________?
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. __________________________?
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. __________________________?
嗯…这些碳酸饮料中的热量已经很高了，还要续杯？我看还是算了吧!
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! ____________.
Doug: Don't worry Liz. If I'm going to get really fat, you should get really fat too! ____________________.
Liz: Wow, ___________________. I need to exercise right now!
