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 can not see deep red. He may think that red, orange and yellow are all shades 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 nearly dark. They show us shape but no color.

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 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（看不见的）colors around.

1. According to the passage, with the help of the “cones”, we can________.

A. tell orange from yellow

B. see in weak light

C. kill mosquitoes

D. tell different shapes

2. Why do some people say it is safer to be driven by women?

A. Women are more careful.

B. There are fewer color-blind women.

C. Women are fonder of driving than men.

D. Women are weaker but quicker in thinking.

3. We can attract and kill mosquitoes by using a_____.

A. red light　　　　   B. yellow light

C. blue light　　　　    D. green light

 

Answer 1

答案：A;B;C
解析：

1、细节推测题。文中说With the aid of the cones in our eyes we can see many beautiful colors by day，而orange和yellow是两种不同的颜色，用演绎法我们可以判定，借助于眼中的cones，我们可以分辨橙色和黄色。 2、因果关系推理题。根据Women are luckier, only about one in two hundred is affected in this matter.女性患色盲的很少，容易分辨红绿灯等各种交通标志，故坐女性驾驶的车比较安全。 3、细节推理题。文中说mosquitoes（蚊子）like blue，蚊子喜欢蓝色，我们可以利用这一特点，用蓝灯吸引蚊子，然后将其捕杀。
