课文讲解
April, a salesperson at an appliance store, approaches Doug, a customer: 在电器用品店里，店员艾波走近顾客道格：
A: Good afternoon. Are you interested in this microwave oven?
午安，你对这一款的微波炉有兴趣吗？
D: Yup. If you don’t want to get irradiated, you’d better stand back while I test it!
对。如果你不想被辐射照到，我测试的时候你最好站后面一点。
A: Oh, that’s just a story someone cooked up. This model is perfectly safe and powerful too.
喔，那只是有人编造出来的说法。这一型绝对安全，效能也很强。
D: So, it’ll cook food much faster than conventional ovens?
所以它烹调食物的速度比普通的烤箱快啰？
A: Definitely. As a regular oven heats up, the hot, fast-moving molecules in the air struggle to penetrate the cold, slow-moving molecules in the food.
当然。一般的炉子加热时，空气中高温且快速移动的分子会不断地穿透食物中冰冷、移动速度慢的分子。
D: And I suppose that’s why my roast meats are always rarest in the middle?
我想那就是为什么烤肉时，肉中间的部分总是最不熟的。
A: Yeah. But microwaves work completely differently, as you can see in this pamphlet.
对啊！但微波作用的方式完全不同，就像你在这本手册上所看到的一样。
D: Oh, I get it! Microwaves ovens emit very-high-frequency radio waves which penetrate the food instantly.
喔，我懂了！微波炉会发出超高频率的无线电波，立即穿透食物。
A: That’s right. Microwaves pass right through most things, until they encounter molecules that are good absorbers of energy.
没错。微波会穿透大部分的东西，直到它们遇到很会吸收能量的分子。
D: I had noticed that they cook juicy and fatty foods much faster than other foods.
我注意到它们烹调多水分多油脂的食物比烹调其他的食物要快得多。
A: That’s true. Some molecules, like water and fat, are better absorbers of microwaves than others. So, will you take this model?
没错。某些分子，像水和脂肪，吸收微波的能力比其它的分子还要好。所以，你要买这一型的吗？
D: Hmmm – I’m still a bit concerned by all the humming and whirring.
嗯…我还是有点担心那些嗡嗡声和呼呼声。
A: Don’t worry, that’s just a metal fan.
不要担心，那只是金属风扇。
D: Really? I’m becoming a microwave fan myself. I’ll take it!
真的？我自己快要变成微波炉迷（双关语：微波炉风扇）。这个我要了！
