中央电大_开放英语3历年试题及答案2007-2010(19)

People who cannot tell all colors apart are said to be color blind. Most color-blind people can see yellow and blues, but confuse reds with greens. It is very rare for a person to be blind to all colors，but they may see everything in shades of black, white, and gray.

It is interesting to note that many color-blind people don‟t even realize that they are color-blind. They don't know that the colors they are seeing and naming are not the actual colors that people with normal vision can see. This can be particularly dangerous when a color-blind person confuses the red and green of a traffic light.

Color blindness is thought to be inherited（遗传）．And although doctors have thought up tests to determine（测定）color blindness, there is no cure to treatment for it.

36. A color-blind person can tell red and green apart correctly. F

37. Many color-blind people are unaware（没意识到）that they are color-blind. T

38. It's especially dangerous for a color-blind person to cross a street when there are no traffic lights at the cross of the streets. F

39. A color-blind person is not allowed to drive. NG

40. Up to now, doctors have found a way to free a person from his color blindness. F

1st August 2005 Dear Jennifer,

Thank you for telling me about yourself. I’d like to let you know more about me too.

As a child，I wanted to be a detective. I thought a detective was really great because he could solve criminal cases to do justice. But my dream never came true. I’m now a librarian, dealing with books every day. The work is nothing thrilling，but I like it. Since there are more and more electronic materials，I hope that we will have an e-library built soon.

Looking forward to hearing from you again.

Best wishes，

Ian
