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.

看到前人一致同意选择D

我想请教eyeglass的功能是可以降低光的强度吗

当然常识可以理解，可是原文没有这个信息啊

请指点

此外在提干中的excessively sensitive做什么解释？

   Answer:

Eyeglasses that ... 限定性从句。

excessively sensitive: 极度过敏

因为原题说Their retinal cells are also not excessively sensitive to red components of moderately bright light啊

顶一下.

还是不明白这题的意思, 以及正确选项说的意思.

烦请哪位牛牛讲解一下好吗? 十分感谢!

Up!

盼望解答!!

为何选D？

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.

我怎么觉得这道题应该是B呢?有谁同意吗?

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.

首先,昏暗的光他们反而能正常看得清,其次,红光在正常强度下他们不是很敏感,换言之, 同样昏暗的光下看红光会比其他光要清楚.

是不是因为文章中，只是涉及到了这种人的信息，并没有阐述其他人的情况，而B中与其他人做了比较

D只是阐述这种人的情况
