题文
About ten men in every hundred have the trouble of color blindness in some way. Women are luckier, only about one in two hundred is affected（感染）in this matter. Perhaps, after all ,it is safer to be driven by a woman.
There are different kinds of color blindness. For example, a man cannot see deep red. He may think that red, orange and yellow are all shades (影子) of green. Sometimes a person can’t tell the difference between blue and green. Only a few unlucky men may see everything in shades of green— a strange world indeed.
Color blindness in human beings is a different thing to explain. In only one eye there are millions of very small things called “cones（锥状细胞）” . These help us to see in the bright light and to tell differences between colors. These are also millions of “rods“（杆状细胞），but these are used for seeing when it is nearly dark. They show us shapes but not colors.
Some insects have favorite colors. Mosquitoes(蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky. With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of the rods we can see shapes at night.

小题1:C
小题2:D

试题分析：
小题1:根据词的意思可知：color“颜色”，blindness“失明”，所以color blindness就是“色盲”的意思。
小题2:通过阅读第一段，我们可知，妇女开车之所以更安全，是因为她们很少是色盲，很容易区分颜色，特别是交通灯。所以本题选D。
小题3:通过These help us to see in the bright light and to tell differences between colors.可知，“cones”能帮助我们分辨颜色，所以本题应该选D“将黄色与橙色区分开”。
小题4:通过 Mosquitoes(蚊子) like blue 可知，我们应该利用蚊子喜欢蓝色的特性，用蓝光吸引蚊子，从而消灭文中。所以本题选C。
小题5:通过阅读全文可知，ACD都太绝对，是错误的；而B的意思是“并非所有的男人在认识颜色方面存在相同的问题。”很明显是正确的。
点评：本文是有关色盲的文章。文章从什么是色盲，色盲的种类，色盲的原因以及动物的色盲等四个方面讲述了色盲。完成本题时应该熟读短文，注意对色盲一些细节的描述，应该根据已有的信息，加以合理的推测。还应注意上下文之间的关系。 |
