说说我的想法
The importance of the ozone layer to terrestrial animals is that it entirely filters out some wavelengths of light but lets others through. Holes in the ozone layer and the dangers associated with these holes are well documented. However, one danger that has not been given sufficient attention is that these holes could lead to severe eye damage for animals of many species.
Which one of the following is most strongly supported by the statements above, if they are true.
A). All wavelengths of sunlight that can cause eye damage are filtered out by the ozone layer where it is intact.黄色部分是原文没有的
B). Few species of animals live on a part of the earth's surface that is not threatened by holes in the ozone layer原文没讲
C). Some species of animals have eyes that will not suffer any damage when exposed to unfiltered sunlight原文没讲
D). A single wavelength of sunlight 原文没讲can cause severe damage to the eyes of most species of animals原文没有
E). Some wavelengths of sunlight that cause eye damage are more likely to reach the earth's surface where there are holes in the ozone layer than where there are not,
A部分光线进入大气 部分光线进不了大气 B黑洞对很多动物的眼睛造成损害
E讲 一些 对眼睛造成损害的光线 通过臭氧洞进入大气
就是A与B的结合
E对
