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. (D)
E.
These people perceive colors other than red in the same way as do most people who do not have the disorder. 作者: 翁羽凌虚 时间: 2011-6-19 10:49
这种病，
外界亮的时候，觉得特别亮，嘛都看不见，
外面暗的时候，和正常一样，
外面亮的时候，对红色的视觉是正常的，
问下面怎么才能支持上面
A 外面一般暗---病眼在暗处不如常眼，不支持题干
B 暗处对红光敏感-----没有落到题干范围内，无关
C 病眼在暗处更厉害----没说暗处病眼更厉害，说在暗处和常人一样，矛盾
D 在外面一般亮的时候，红墨镜把外面光线变成等强度的红色，能帮助病眼看
外面，---完全支持，虽然看到的是红色背景，但是还是可以算得视觉正常。
E 红色以外，----没说红色以外会如何，无关作者: alicejingli 时间: 2011-6-19 21:22
