Question

About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!

There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green--a strange world indeed.

Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.

Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.

【解析】

試題分析：文章講的是色盲的相關(guān)知識(shí)。男性中，十個(gè)人中會(huì)有一個(gè)人患有色盲，而女性的概率是二百分之一。色盲有不同的形式，有的分不清紅色和綠色，有的無(wú)法區(qū)分藍(lán)色和綠色。

1.About ten men in every hundred suffer from color blindness in some way.”和二、三段首句“There are different forms of color blindness. ...Color blindness in human beings is a strange thing”可知，文章講的是色盲，故選D。

2.things called “cones”. These help us to see in a bright light and to tell difference between colors.”可知，眼球中的錐體細(xì)胞幫助人們看到強(qiáng)光下的物體，還幫助我們分辨顏色，故選D。

3.only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!”可知，女性患色盲的概率很低，因此，理論上來(lái)講，讓女性開(kāi)車(chē)會(huì)更安全，故選B。

4.There are different forms of color blindness. ...a man may not be able to see deep red ...a person cannot tell the difference between blue and green”可知，色盲有著不同的形式，有的無(wú)法辨別深紅，有的人無(wú)法區(qū)分藍(lán)色和綠色，故選A。

5.Mosquitoes prefer blue to yellow.”可知，蚊子喜好藍(lán)色的光，因此，我們可以用藍(lán)光來(lái)滅蚊，故選C。
