The traffic lights were red when the driver reached them．To the surprise of his passenger,the ear did not slow down．Unexpectedly the passenger was thrown forward in the vehicle as the driver put on his brakes at the last moment．The car stopped just in time. "Sorry,I didn't notice the light．I thought it was green until I saw that it was the top light which was shining." This strange story is quite true．About ten men in every hundred are color blind in some way;women are luckier--only about one in two hundred suffers from 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 the same as green. People often like one color more than others．Blue is the color of the sky and sea．Green makes us think of fields and trees．Red is the color of blood and makes some people think of danger．Black is the color of night．In the dark we cannot see what is around us so we are sometimes afraid of the unknown and do not like black as a color.One is considered as a color blind man if__.A.he can see the difference between red and deep red B.he can see the difference between blue and green C.he can't tell the difference between orange and green D.he thinks green is the same as blue
