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.

1.“Color blindness” means ________ in Chinese.

A. 盲目        B. 无色      C 色盲    D 讨厌颜色

2. Some people say it’s safer to be driven by women because ________.

A. women drive more carefully

B. women are better at driving than men

C. women can see things more clearly

D. there are fewer color — blind women

3.With the help of the “cones”, we can ________.

A. tell different shapes        B. kill insets

C. see in the dark            D. tell orange from yellow

4. We can attract and kill mosquitoes by using a ________ light.

A. red       B. yellow     C. blue     D. green

5. Which of the following sentences about color blindness is TRUE?

A. None of men can see deep red.

B. Not all of men have the same problem in recognizing colors.

C. None of men can tell the difference between blue and green.

D. All of men see everything in shades of green.

About ten men in every hundred suffer from colour blindness in some way. Women are luckier. Only about one in two hundred is affected in this matter. So some people say it is safer to be driven by women.

There are different forms of colour blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades（色调）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.

Colour blindness in humans is a strange thing to explain. In our eyes there are millions of very small things called “cones”. These help us to see in a bright light and to tell differences between colours. There are also millions of “rods”, but these are used for seeing when it is nearly dark. They show us shapes but no colour.

Some insects have favourite colours. 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 humans also have favourite colours. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colours 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（看不见得）colours around us.

1.With the help of the cones, we can 　　　　　　 .

A. see in a weak light

B. tell different shapes

C. kill mosquitoes

D. tell orange from yellow

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

A. Women are more careful.

B. There are fewer colour-blind women.

C. All of them see everything in shades of green.

D. None of them has trouble in recognizing colours.

3.This passage is mainly about　　　　　　 .

A. colour and its surprising effects

C. colour blindness

D. the invisible colours around us

People have been interested in color and its effects for hundreds of years. More recently, research has turned to the question of how different colors can help students learn better.

Believe it or not, some colors can affect a child’s IQ. For example, a simple black and white color scheme may cause IQ to become low, while the good use of reds and oranges may raise it as much as 15 points. Be careful not to use too much, however, a little red is exciting, but too much makes people uncomfortable. Bright yellow is exciting to the brain, while the color green is thought to encourage creativity.

Use blue and green to calm yourself. Blue, especially, can cause you to calm down. Something blue in a reading area, for example, may help you focus (集中于) on what you are reading. But too much dark blue can make you sad, so use light blue on walls or large floor areas.

If you are struggling to read, try a different color of paper. According to a study, 80 percent of children who had difficulty in reading improved their understanding when they put something grey or blue over their pages. Do not use bright colors here, as they become difficult to look at after a while.

However, use bright colors like red, orange and yellow for important points. These colors attract the eye and may help you notice details.

The same color of the walls of a room do not help you focus on your studies , but make you slow in understanding. Colors, on the other hand, make the senses active and encourage learning. Use primary colors red, yellow and blue in a proper way. Then how do you make your choices of color? It mainly depends on your space, the lighting and the function of the room.

1.The color grey may help you ________.

A. read better　　 B. calm down　　 C. raise IQ　　 D. feel creative

2.If you want to remember some important facts, you may use the colors ________.

A. green and blue　　 B. grey and blue　　 C. red and yellow　　 D. black and white

3.Which is most important when you choose the color for your room?

A. Your IQ and abilities.　　 B. The use of your room.

C. Your likes and dislikes.　　 D. The location of your room.

4.Which might be the proper title for the passage?

A. What should we learn about colors?　　 B. Why are people interested in colors?

C. Where should we be careful with colors?　　 D. How do colors affect our learning abilities?
