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!

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。

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）。

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。
