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.

5.C

【解析】

試題分析：本文說明方，男性中有百分之十的人是色盲，女生的比例較低，從這個(gè)角度，所以女生開車比男生更安全，色盲不僅僅人類有，動物也會出現(xiàn)。

1.D 主旨大意。第一段提出男女色盲的問題，第二段There are different forms of color blindness.提出不同顏色的色盲，第三段Color blindness in human beings is a strange thing to explain色盲很難解釋，第四段許多昆蟲也有這種現(xiàn)象，故選D項(xiàng)。

2.D 細(xì)節(jié)題。根據(jù)第三段These help us to see in a bright light and to tell difference between colors，用來區(qū)分顏色 故選 D項(xiàng)。

3.B 細(xì)節(jié)題。根據(jù)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，所以選擇B項(xiàng)

4.A細(xì)節(jié)題。根據(jù)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.在某種情況下，男人可能看不到紅色，在極少數(shù)可能情況下，這個(gè)也可能看不到綠色，所以BCD三個(gè)選項(xiàng)過于的肯定或者否定，判斷出A項(xiàng)正確。此類題注意not all 和none ,這可能就是解題的關(guān)鍵。

5.C細(xì)節(jié)題。根據(jù)最后一段Mosquitoes prefer blue to yellow.根據(jù)語法 Prefer blue to yellow ,更喜歡藍(lán)色。吸引蚊子用藍(lán)色的燈，故選C項(xiàng)。
