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.

(答案→)D
解析：本文说明方，男性中有百分之十的人是色盲，女生的比例较低，从这个角度，所以女生开车比男生更安全，色盲不仅仅人类有，动物也会出现。
【小题1】D 主旨大意。第一段提出男女色盲的问题，第二段There are different forms of color blindness.提出不同颜色的色盲，第三段Color blindness in human beings is a strange thing to explain色盲很难解释，第四段许多昆虫也有这种现象，故选D项。
【小题2】D 细节题。根据第三段These help us to see in a bright light and to tell difference between colors，用来区分颜色 故选 D项。
【小题3】B 细节题。根据第一段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.，女性色盲率低，故更安全，所以选择B项
【小题4】A细节题。根据第二段In some cases a man may not be able to see deep red和In rare cases an unlucky man may see everything in shades of green － a strange world indeed.在某种情况下，男人可能看不到红色，在极少数可能情况下，这个也可能看不到绿色，所以BCD三个选项过于的肯定或者否定，判断出A项正确。此类题注意not all 和none ,这可能就是解题的关键。
【小题5】C细节题。根据最后一段Mosquitoes prefer blue to yellow.根据语法 Prefer blue to yellow ,更喜欢蓝色。吸引蚊子用蓝色的灯，故选C项。
