以下是引用小I爱漂漂在2005-2-16 12:40:00的发言: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。 |
