标题: [求助]GWD-27-2 急求NN解答.
GWD-27-Q2:
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:
- There will be applications in which the speed attainable by an electronic switch is not essential.
- 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.
- There will be applications for computer chips in environments where the chips may have to survive intense radiation.
- 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.
- Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.
答案是E . 麻烦各位NN鼎力相助!
感激不尽.

有2种chips Micro-Mechanics’ chip 优点是不怕强辐射.但是速度慢,一种是electronic switches的chip 优点是速度快一点但是怕辐射.
题目要求是支持使用Micro-Mechanics’ chip,那么就要找一些能体现Micro-Mechanics’ chip 优点和electronic switches的chip缺点的例子.但是要选exception的哦!(相当于选支持electronic switches)
A,速度不重要,那么electronic switches没有优势了.
B,装了12,000 switches 后,lectronic switches更容易坏也不行.
C,要求chip能survive intense radiation,体现了Micro-Mechanics’ chip的优势,不行.
D,无关选项.
E,Manufacturer可以让chip免于受radiation的影响.避免electronic switches的缺点.选这一个.

哦.谢谢你的解释.当时对于B一直发愣.没想明白.

2楼解释的非常清晰
一看就明白了
大感谢您…

感觉这个题目比较绕~做得时候完全是一头雾水~二楼的NN解释得太好了!非常透彻!谢谢!
作者: bear_w 时间: 2009-3-23 17:47
不错,明白了。

很好,谢谢2楼!
作者: lannyll 时间: 2009-10-23 18:47
基本同意2楼的观点
不过D似乎不应该是无关选项吧,题目要找不能体现Micro-Mechanics’ chip 优点的选项,如果D是无关,那岂非也属于不能体现Micro-Mechanics’ chip 优点的选项之一
我开始选的是D,不过仔细一想,D说的应该是一些设备用CHIP有其他的组件能够在辐射时发挥作用
这样一看,D应该也是能体现Micro-Mechanics’ chip 的优点的
不知道是8是这么理解的?

大致方向没错,题目要求的是选出不能让 M 公司的芯片有市场的选项。
稍微更正一下 2楼的 B 选项
B、(其他公司生产的)只有12000 switch的芯片比 M 公司的更容易被辐射损害—— M 公司产品有市场的原因,不能选

支持7楼8楼
D说的是一些使用了CHIPs的设备有其他的零件能够不怕辐射,即除了chips,其他零配件不怕辐射,说明chips是设备中能不能不怕辐射的关键因素,从而支持了Micro-Mechanics’ chip的市场重要性,有利于市场销售,所以不能选

二楼解释的好好!

good~
作者: peter3008 时间: 2010-10-20 06:50
题目要看清楚啊,我以为是must be true题目,结果看到D这个无关选项就直接选了,没有想到是削弱题型
作者: shirryzhan 时间: 2012-6-6 23:16
It asks which choice doesn’t support the conclusion that Micro-Mechanic’s chip is better.所以只要选出对于M公司不利的选项
A.It says there would be applications in which the electronic switches would not take the advantage of speed. That is to say, the speed issue
would not weaken Micro-Mechanic’s chip.
B.使用12000转的电子芯片没有M公司的芯片抗辐射。
C.It give M-chips an opportunity to prove itself, because radiation resistance is its advantage.
D. After radiation, the devices using computer chips are also functional in some parts. Actually, it doesn’t help M-chips nor the Electronic ones. Just a neutral attitude.
E. As long as manufacturers are able to protect electronic chips against radiation, there would be dangerous for M-chips to keep its advantage as radiation resistance.

恩...二楼的解释都合理,除了D外, D不是无关选项。
如果说一个device除了computer chip不受辐射影响外,其他都不灵了,那这个computer chip同样没有意义
D的存在证明了这个防辐射芯片的价值

感謝樓上清楚的解釋!!!
作者: lsshi8947 时间: 2013-7-2 06:13
个人思路:错选D,注意文章问题是下面哪一项不能说明这种chip有市场?d说一些设备含有防辐射组件(说明还有另一些没有),因而chip是有市场的,所以错
作者: lisa1009 时间: 2014-10-4 10:47
我开始也以为D无关选了D,15楼正解啊
如果一些device的其他组成部分也受radiation的影响,那么Micro-Mechanics's chip防radiation也没用啊,这些devices照样不能运行
作者: AnnieFFish 时间: 2016-10-24 20:07
没想通D
看了15楼的解释 终于明白了!
作者: Aruzaaaa 时间: 2017-8-17 20:04
同意!
