情景对话:
A: Mommy, what's this?
B: It's a piece of charcoal.
A: What do people need it for?
B: People burn it to produce heat.
A: Then it's like the coal. Miss Castle told us in class that people also burn coal to produce heat as well as electricity.
B: Right! Coal, a solid fuel, is the largest source of energy for the generation of electricity worldwide. Well, what else did Miss Castle tell you?
A: Urn, she said that coal is primarily composed of carbon,but I know there are also some other elements in it.
B: Yes. And where can we find coal?
A: In a coalfield.
B: Right. Coal is extracted through mining. And Tommy, do you remember Uncle Ben used to be a coal miner?
A: Yes, I do, but isn't it a long time ago?
B: Ha-ha, you're right. Now tell me if there's anything more that Miss Castle has taught you about coal.
A: She also told us coal is a fossil fuel. But mommy, what's"fossil fuel"?
参考译文:
A:妈妈，这是什么?
B:是一块木炭。
A:人们用它来干吗?
B:通过燃烧它产生热量。
A:那它就和煤一样。卡什老师上课告诉我们人们还是烧煤以产生热量和发电。
B:正确!煤是一种固体燃料.是全世界用于发电的主要能源。好了，卡什老师还教了你们什么?
A:嗯，她跟我们说煤的主要成分是碳，不过，我知道里面还有其他一些元素。
B:没错。那我们在哪儿能找到煤呢?
A:煤田里。
B:说得对，人们开矿来采煤。汤米，你记得本叔叔以前在煤矿当过矿工吗?
A:我记得，不过那是很早以前的事了吧?
B:哈哈，没错。现在跟我讲讲卡什老师上课还有没有教你们其他什么跟煤有关的内容。
A:嗯，她还告诉我们煤是一种矿石燃料。但是妈妈，什么是“矿石燃料”啊?
