第十九篇
Graphene’s Superstrength
1 .What would change the future of electronics according to engineers?
工程师认为什么将会改变电子设备的未来？
A Big technology. 重大科技。
B Creative ways. 富有创意的方法。
C Graphene. 石墨烯
D Both A and B. A和B两项内容。
【教材解析】C 第一段最后一句提供了答案：工程师将眼光投向石墨烯，一种由碳原子组成的超薄材料，这种材料能够改变电子产品的未来。
【芒果备注】
Big technology comes in tiny packages.“重大的科技以‘微型’来呈现”。这里in tiny packages表示方式，不要把come in理解成表示“进来”的短语。tiny packages的字面意思为“微小的包装”，实际上就是说小的产品容纳了重大科技成分在里面，后面给了例子cell phone和personal computer。
2. According to the second and third paragraphs，what is true of graphene?
根据第二段和第三段的内容，下列关于石墨烯的说法那个是正确的？
A It can be used to make paper. 可用于制作纸张。
B It is possible to see it with our naked eye. 肉眼是可能看到的。
C It is easy to find graphene. 找到石墨烯很容易。
D It is possibly the thickest material in the world. 很可能是世上最后的材料。
【教材解析】C 第二段倒数第二句告诉我们，25,000 层石墨烯才能堆砌成一张普通白纸的厚度，这是为了说明石墨烯是多么的薄，而不是说它可以用来造纸，所以A不是正确答案。第三段最后一句说明石墨烯就在我们周围，因此C是答案。B和D的表述内容都与该两段内容不符合。
【芒果备注】
This year's Nobel Prize for Physics（诺贝尔物理学奖） has been awarded（授予） to Andre Geim and Kostya Novoselov from the University of Manchester4，UK. for the discovery of graphene. Graphene isn't just small, it's “the thinnest（最薄的） possible material in this world，” says Novoselov. He calls it a“wonder material.” It's so thin that you would need to stack about 25,000 sheets just to make a pile as thick as a piece of ordinary white paper.（这里有一个so that结构，意思是“如此……以至于……”，stack意思为“把……堆在一起”此句意为：石墨烯极薄，25000片石墨烯叠放在一起才与一张普通白纸一样厚。） If you were to hold a sheet of graphene in your fingers，you'd have no idea because you wouldn't be able to see it.
Carbon is one of the most abundant（丰富的，充裕的） elements in the universe. Every known kind of life contains carbon. Graphene is a sheet of carbon, but only one atom thick. You don't have to look far to find grapheme —it's all around you.（far的意思为“遥远的”，look far的字面意思是“到远处如寻找”。这里可以理解为“费力去寻找”。）
3. Which of the following can be used to replace the word “apply” in paragraph 4?
下列哪个单词能代替第四段中的“apply”？
A request. 请求，需要
B polish. 磨光，使发亮
C use. 使用，利用
D put. 放置
【教材解析】D apply... over：将……涂（敷）在……上。
【芒果备注】
If you want this high-tech wonderstuff（神奇物），all you need is a pencil，paper and a little adhesive tape. Use the pencil to shade（涂黑，使阴暗） a small area on the paper, and then apply a small piece of adhesive tape（胶条） over the area. When you pull up the tape（由此处的拉起胶条可知，前面的apply a small piece of adhesive tape意思一定是把胶条贴在涂黑的那块纸上，所以put在此可以代替apply），you'll see that it pulls up a thin layer of some of the shading from your pencil.（此句的意思是：当你拉开胶条你会发现它粘起了很薄的一片铅笔涂的阴影。） That layer is called graphite，one of the softest minerals in the world.
4. Which of the following is NOT meant in the last two paragraphs?
下列哪项不是最后两段要表述的意思？
A Graphene is made of graphite, one of the softest materials in the world.
石墨烯由石墨构成，石墨是世界上最柔软的材料之一。
B Graphite is made of layers of graphene，the thinnest material in the world.
石墨是由多层石墨烯构成，石墨烯是世界上最薄的材料。
C When we get to the thinnest possible layer of graphite，we find graphene.
我们可能得到的最薄的那层石墨就是石墨烯。
D With a pencil，a sheet of paper and a piece of adhesive tape，we can find graphene.
利用一支铅笔，一张纸，一段胶条，我们就能找到石墨烯。
【教材解析】A 最后两段告诉我们，用一张纸，一支铅笔和一片胶带就能找到石墨烯；无数层石墨烯构成石墨，当铅笔留在纸上的石墨被胶带剥离到最薄一层时，我们就得到了石墨烯。因此只有A不是最后两段的表述内容。
【芒果备注】
If you want this high-tech wonderstuff, all you need is a pencil，paper and a little adhesive
tape. Use the pencil to shade a small area on the paper, and then apply a small piece of adhesive
tape over the area. When you pull up the tape, you'll see that it pulls up a thin layer of some of
the shading from your pencil. That layer is called graphite, one of the softest minerals in the world.
Now stick the same piece of tape on another sheet of paper and pull the tape up—there should be an even thinner layer（even修饰thinner，更薄的一层）, this time left on the paper. Now imagine that you do this over and over（这里的over and over意思是说将粘了石墨的胶条贴在纸上后拿开，再用新的胶条去粘留在纸上的石墨，然后再贴在另外的纸上，如此反复。）, until you get the thinnest possible layer of material on the paper. This layer would be only one atom thick, and you wouldn't be able to see it. Graphite is made of layers of graphene（石墨是由多层石墨烯构成，答案A的表述说反了。），so when you get to the thinnest possible layer, you've found graphene.
5. Graphene's superstrength lies in the fact that
石墨烯的超强力量来自于
A It is the thinnest material in the world.
它是世界上最薄的材料。
B It is made of the most abundant elements in the world.
它是由世上最多的元素构成。
C It can help to make electronic components smaller.
它能使电子元件更小巧。
D It helps engineers to produce more sensitive electronic products.
它帮助工程师制造更加敏感的电子产品。
【教材解析】C 第一段提供了答案。随着电子产品越来越小，需要更小的电子组件（components) ，而石墨烯作为最薄的材料可以帮助工程师实现这一目标。这就是石墨烯力量所在。
【芒果备注】
Big technology comes in tiny packages. New cell phones and personal computers get smaller every year, which means these electronics require even smaller components on the inside. Engineers are looking for creative ways to build these components, and they've turned their eyes to graphene, a superthin material, made of carbon, that could change the future of electronics.（最后点出that could change the future of electronics“石墨烯能够改变电子产品的未来”，由此足见石墨烯的超强力量所在。）
