Q31:
People with a certain eye disorder are virtually unable to see in moderately bright light, which seems to them unbearably intense, since the cells of their retinas are overwhelmed by moderately bright light. These people do, however, show normal sensitivity to most components of dim light. Their retinal cells are also not excessively sensitive to red components of moderately bright light.
The information above best supports which of the following hypotheses about people with the disorder described, if they have no other serious visual problems?
A. In all moderately dim light in which people without the disorder can read large print, people with the disorder cannot read such print.
B. In an otherwise darkened concert hall, these people will see a dimly illuminated red exit sign more clearly than small dim white lights that mark the aisles.
C. These people typically see more acutely at night and in dim light than do most people who do not have the disorder.
D. Eyeglasses that are transparent to red components of light but filter out other components of light help these people see in moderately bright light.
E. These people perceive colors other than red in the same way as do most people who do not have the disorder.
答案是D
看不明白题, 也看不明白选项. NN能帮忙解答一下吗?
十分感谢的说!

People with a certain eye disorder are virtually unable to see in moderately bright light
Their retinal cells are also not excessively sensitive to red components of moderately bright light.
由以上原文得出下面结论:很理解读不懂题干的心情,刚好刚刚做完这道题,就试着和楼上的分享一下,有不对的地方请指出。
原体题干:眼睛disorder的人在moderate的光下看东西有问题,因为对于他们的视神经来说,moderate的光太强了;但是这些人在dim光有正常的光敏感度,同时他们对moderate光里的红光也不是超级敏感,(意即对红光的敏感度是正常的)。
d答案:这些人在moderate 光下戴上这样一种眼镜:保留红光(透明的),过滤其他的光,对他们看东西有帮助。

括号中的是怎么推出来的呢?
为什么过虑红光保留其他光对他们看东西是有帮助的?
D.
可以排除其他答案:
a. 如果large print is red, people with the disorder CAN read <= " not excessively sensitive to red "
b. in dark, these people ONLY show normal sensitivity , no better
c. 用和 b 一样的理由排除
e. 和原文观点相反

其他光线太强,导致病人看不清,因此 "过滤其他光,保留红光”是有帮助的。
i can't understand why B is not right ?
what the word 'otherwise' means?
B. 在一个几乎漆黑的大厅里,对于这些有eye disorder 的人,一个昏暗的红色exit sign要比一个小的昏暗的白色光源清楚。
但原文中只说,这些人既能看清昏暗的光(包括白色和红色),又能看清一般亮度的红色的光。并没有比较dim white 和 dim red, 所以错。
otherwise可以这么理解:去掉这个otherwise,大厅就是漆黑的。但因为有后文的red exit sign 和 white light, 所以大厅还不至于彻底漆黑(在一个几乎漆黑的大厅里)。
本题信息
1. people woth eye disorder 在 moderately bright light中什么也看不见《=bright light intense对他们来说太强烈了(推出敏感=〉看不见,那么不敏感就有可能=>看见了)
2这群人对dim light的大多数成分不敏感=>这帮人在dim light可以看见)
3这群人对moderately bright light的red成分也不敏感=>如果moderately bright light只有red,那么就不敏感了=〉那么在moderately bright light就可以看到了
答案对照选就可以了
D: Eyeglasses that are transparent to red components of light but filter out other components of light help these people see in moderately bright light.
那按照选项的意思还有大家的翻译:“过滤其他光,保留红光”那戴眼镜的人岂不是只看的见MODERATELY BRIGHT LIGHT下的红光了?其他颜色都看不见了?但是常识告诉我们不是这样的呀,那是怎么回事呢???烦请大家再帮忙看看!!

请看一下题干
People with a certain eye disorder are virtually unable to see in moderately bright light, which seems to them unbearably intense, since the cells of their retinas are overwhelmed by moderately bright light. These people do, however, show normal sensitivity to most components of dim light. Their retinal cells are also not excessively sensitive to red components of moderately bright light. 我解释一下这个题: 有某种眼疾的人感到对于正常人感觉正常的光线有无法忍受的强烈,除了红光外。也就是说,正常强度的红光对于这种眼疾患者是可以接受的,但其他正常强度的光线对于这类眼疾患者是不能接受的。 D说一种眼镜,能让红光穿透,而过滤其他光线(即降低它的强度)对患者看正常光线有帮助。 不知道你明白没有。
D.
可以排除其他答案:
a. 如果large print is red, people with the disorder CAN read <= " not excessively sensitive to red "
b. in dark, these people ONLY show normal sensitivity , no better
c. 用和 b 一样的理由排除
e. 和原文观点相反
还是不太明白.望NN解答
这道题目关键还是要读懂题目吧。
题目说:有眼病的人对正常关极度敏感(太敏感,太强烈),以至于实质上不能看到正常光。然而他们对于微弱光和正常的红光有象常人一样的敏感度。
问可以推出什么。就是C所说的,拿正常光来,过滤掉其他的,只剩下红光,这些有眼病的人就可以看到了。
我原来也选了B, 后来仔细一看,确实应该选D
正确答案楼上的几位解释的很清楚了,我试着解释B的错误
文章中有说过, These people do, however, show normal sensitivity to most components of dim light.也就是说在dim的情况下, 他们的反应是正常的,也就说他们看到dimly illuminated red exit sign 和small dim white lights 的清楚程度是一样的.
不知道理解是否正确?
这题很难读懂 因为推理貌似没有联系
这些人对暗光的敏感是正常的 其实暗光大多由红外线组成 这样再去理解 他们对白光里的红光也不过度敏感 就容易多了
