题目内容
9．Imagine what you could do with a machine that could make things disappear．（36）F In the books of J．R．R．Tolkein，Bilbo Baggins finds a ring that can make him disappear．Of course，there's also poor Harry Potter，who used his invisibility cloak （隐形斗篷）to hide from danger．
Now that you've got some ideas，it's time for the hard part：building the cloak．（37）G
An invisibility cloak has to cheat anything or anyone who might be watching．In order to understand how something can be seen，it's important to understand how we see．
Human beings can only see objects that reflect light waves．These waves enter the eyes and are then processed by the brain．However，if an object doesn't reflect light，then the waves don't enter the eyes，and the brain doesn't process．（38）C
Cummer was part of a team of scientists from Duke University，including David Smith and David Schurig，who built the world's first version of an invisibility cloak．（39）EHe in May said that an invisibility cloak was possible and Pendry was not the only one thinking about a disappearing act．At the same time，a Scottish physicist，Ulf Leonhardt published a paper on building invisibility equipment．
"It wasn't easy，"says Cummer．"As often happens in science and research，it didn't work very well the first time．That first cloak didn't work like Harry Potter's-（40）BSo the research is still under way．"
A．Would you like an invisibility cloak that works just like the one Harry Potter got from his father？
B．The scientists didn't actually seeanything disappear．
C．So building an invisibility cloak is building something that doesn't reflect light．
D．Researchers in England and the USA have found the materials to build such a cloak．
E．They had been inspired by the work of a British physicist，John Pendry．
F．For inspiration，you could read some books．
G．To do that，you have to give up science fiction and turn to real science．
分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了一个关于制造隐形斗篷的研究，然而制作隐形斗篷并不容易，尽管已经出现了隐形斗篷的第一个版本，但并不能像哈利波特的斗篷一样使物体消失，研究还在不断尝试中．
解答 36．F．推理判断题．根据文章第二段"In the books of J．R．R．Tolkein，Bilbo Baggins finds a ring that can make him disappear"在J．R．R．Tolkein的书，Bilbo Baggins 发现了一个可以让他消失的戒指，可推测前文应为为了获得灵感，你可以读一些书；故选F．
37．G．推理判断题．根据文章第三段"An invisibility cloak has to cheat anything or anyone who might be watching．In order to understand how something can be seen，it's important to understand how we see"一件隐形斗篷必须欺骗任何会被看到的人活事物，为了了解什么是可以被看到的，这是非常重要的去了解我们如何看到事物的；可推测前文应为要制作隐形斗篷，你必须放弃科幻小说，转向真正的科学；故选G．
38．C．推理判断题．根据文章第四段"However，if an object doesn't reflect light，then the waves don't enter the eyes，and the brain doesn't process"可知如果一个物体不反射光，那么波不进入眼睛，大脑不处理，人们便看不见；因此前文为所以建立一个隐形斗篷是建立一个不反射光的东西；故选C．
39．E．推理判断题．根据文章第五段：Cummer was part of a team of scientists from Duke University，including David Smith and David Schurig，who built the world's first version of an invisibility cloak，Cummer是一队来自杜克大学的科学家，包括David Smith和David Schurig，他们建造了世界上的隐形斗篷的第一个版本，可推测后文为他们曾被英国物理学家John Pendry的工作鼓舞；故选E．
40．B．推理判断题．根据文章最后一段"As often happens in science and research，it didn't work very well the first time．That first cloak didn't work like Harry Potter's"正如科学研究中经常发生的那样，第一次总是不能做的很好，这第一件斗篷并没有像哈利•波特那样；可知后文为科学家们实际上并没有看到什么东西消失；故选B．
点评 七选五阅读是完成性阅读，和完形填空很类似，不同的是一个选词，一个选句子．解题时，要注意上下文语境，充分考虑信息词（选项中和空格前后句子中相同或相近的词），选出最符合语境的句子．
