GWD 27 Q2看了一些帖子还是有两个选项不明白。。想了很久。。

ssxxtt27

Electronic computer chips made of tiny silicon wafers 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 will 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 an electronic switch is not essential.（会有软件不要求速度）

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.（相同速度的chips，微芯片更不易受损）

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.

答案是E  E我没疑问
我不知道CD错哪了。。看了不少帖子，对这讨论不多呢。。
我的理解 C  存在软件可以在computer chips严重的辐射中（不就削弱了新技术的价值了么）
                D  一些设备可以有其他部分，来保证即使computer chips遭遇辐射也可以继续运转（这样不就不需要Micro-Mechanics’ chip 了么）
先谢了~~~

自己顶一下！

C是说 chips必须经受的住强烈辐射，是支持Micro-Mechanics’ chip的~
D是说 一些设备有其他部分被辐射了还是可以运行，也就是说，只要chip可以经受的住辐射，其他部分是没问题的，还是支持了Micro-Mechanics’ chip抗辐射~
open to discuss~

不好意思，还是不太明白。。。C说“将会有能适应强辐射的applications”，不就是说“没有Micro-Mechanics’ chip也没有关系（反正能防辐射的app马上就有了）”吗?谢谢啦

看到D我发现了一个问题.C和D里的computer chips指的是什么。。。是electronic computer chips还是Micro-Mechanics’ chip？你的理解应该是后者，我理解的是前者。。。这可能是问题的根本所在。。。

huisang

There will be applications for computer chips in environments where the chips may have to survive intense radiation.
这句话的意思我理解不是“将会有能适应强辐射的applications”，而是有applications for computer chips，但运行环境是chips可能必须抗的住强辐射~所以支持了能抗辐射的Micro-Mechanics’ chip~

huisang

我理解的是computer chips就是电脑芯片的泛指~electronic computer chips和Micro-Mechanics’ chip都是computer chips~

C选项你理解错了，它是说会有applications要求chips工作在有辐射的环境中，那当然micro chips好

明白了！这么一句话我怎么理解错了呢。。。哎。。。

嗯！终于明白了！
