Electronic computer chips made of tiny silicon wagers now regularly contain millions of electronic switches. Unfortunately, electronic switches that are this small cannot withstand intense radiation. Micro-mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage. The switches will, however, be slower than electronic switches and the chip wil contain only 12,000 switches.
For there to be a market for Micro-mechanics' chip as a result of the apparent advantage described above, each of the following would have to be true EXCEPT:
A There will be applications in which the speed attainable by anm electronic switch is not essential
B Switches used on electronic chips that contain only 12,000 switches are more vulnerable to radiation damage than the switches on Micro-mechanics' chips may have to survive intense radiantion
C There will be applications for computer chips in environments where the chips may have to survive intense radiation
D Some devices in which computer chips will be used will have other components that will be able to function during or after exposure to radiation
E Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.
the correct answer is E.
Why D is not correct?
ding
AC应该都可以理解
B中表明M的chip好, D中表明用M的chip没有副作用, 不会影响其他component
而E是无关选项
D Some devices in which computer chips will be used will have other components that will be able to function during or after exposure to radiation
E Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.
D说的是computer 需要一些部件能够在radiation下工做正常.也就是说文章的那个new switch 是有用的.
E说的是Manufacturers有办法(注意没说是那个new switch)能够保护chips在radiation下不受损. 这不是说new switch 是有用的,而是在说new switch 可能没有用武之地了.
要仔细体会DE说的差别.
所以E是对的.
谢谢斑竹，关于E的解释我看懂了，但是D还是不明白。
D直译过来是说，芯片用的某些装置里会有其它的一些部件，也能够在受到辐射时或者之后正常工作。
既然都能够正常工作了，那要这个new switch有什么用呢？不正好说明了这个new switch没有advantage吗？
还是其它的意思呢？我想应该是我理解错了吧。但是那个be able to不是表能力吗？

你说的"D直译过来是说，芯片用的某些装置里会有其它的一些部件，也能够在受到辐射时或者之后正常工作"
是对的.可是你说的"既然都能够正常工作了，那要这个new switch有什么用呢"是不对的.那个D是用的将来时态.D是暗试说
"因为芯片用的某些装置里会有其它的一些部件，也能够在受到辐射时或者之后正常工作,所以那个new switch是有用的",而不是不需要new switch.
你再仔细体会一下D的含意.
D的意思就是说，new switches可以在during or after exposue to radiation后工作，言下之意思old switches 不能。
所以，在other parts都能在during or after exposue to radiation后工作的情况下（D的意思），new switches比old switches 有apparant advantages.
For example, a car can not run anymore because one of the tires is flat. However, everything else on the car still works, so you don't want to dump the whole car only because one of the tires is flat. D is saying that if you can change the old tire into a new one that won't get flat easily, that would be nice.

哈，终于明白鸟。。。D是在说除了那个new switch之外，别的部件也必须在辐射之后还能用得着，否则所以东西都坏了，只有那个switch是好的也是白搭。。。
不明白为什么是E
请指点 以下巴
E Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.
制造商能够去保护电脑那些电路不受强辐射干扰，当这种保护需要的时候
就是说新的电路能够自己保护不受辐射没什么用
对否？
感觉C也可以，请教NN
B: Switches used on electronic chips that contain only 12,000 switches are more vulnerable to radiation damage than the switches on Micro-Mechanics’ chip will be.
应用于只有12000个开关的electronic chips 的开关，比M芯片上的开关受到辐射时更加脆弱；
意思就是，M的芯片好，符合原文意思。
还是感觉这题怪怪的 明明问题问的是have to be true必要条件
答案里都像是充分条件。。。
Ans:E
请教各位大大们，这题我左看右看搞不清楚在问什么？？
这题应该要找什么答案？？？
UP
这题目问那个是芯片的优势（就是有市场价值），除了——
E是唯一不能让芯片发挥作用的一种情况，所以就是它了。

还是不知道题目再谐什麽~~
误选B，栽在限定12,000上了
其实这道题D选项sunjie已经说的很清楚了。附上我的进一步分析

解析：原文推理：electronic switches不能忍受intense radiation，Micro-Mechanics’ chip可以忍受，但是slower than electronic switches，结论说Micro-Mechanics’ chip有市场，也就是说就算慢也可以
思路：要加强有市场，就要强调Micro-Mechanics’ chip能够抗击radiation damage的优点，淡化速读慢的缺点。
A：说速度不重要，自然就去除了慢这个缺点，也就有市场了。
B：相同的速读下electronic chips比Micro-Mechanics’ chip更脆弱，加强了Micro-Mechanics’ chip抗击radiation damage的能力
C：chips may have to survive intense radiation说明抗击radiation damage很重要，因此有市场
D：错误是认为其他组成部分是否能够忍受radiation damage和Micro-Mechanics’ chip有市场无关。但是这个选项说明使用Micro-Mechanics’ chip没有副作用。之前使用electronic switches的时候因为不能忍受intense radiation，所以只能在弱radiation的情况下使用，现在换成了Micro-Mechanics’ chip，也就是说可以在强radiation下使用，但是如果装置中的其他零件不能忍受强radiation的话，就算是换上了Micro-Mechanics’ chip也不能用，所以也就没有市场了。这个选项排除了这种情况。
E：正确，很明显的错误，electronic computer chips可以被保护不受radiation damage，那么就不需要Micro-Mechanics’ chip了，削弱结论
