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 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 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 " . These help us to see in the bright light and to tell differences between colors. These are also millions of "rods" ,but these are used for seeing when it is nearly dark. They show us shapes but not colors. Some insects have favorite colors. Mosquitoes 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. 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

Today is Tom's birthday. After school he walks past the shop on the street corner. He looks at the window. That pair of trainers is still there. He really wants to have them very much. He was very sad and walks away. He knows his mother can give him anything he likes if she can. But he also knows she has no money and the trainers are too expensive. He doesn't go home at once because his mother could notice his worry. So he goes to the park and sits on the grass. Then he sees a boy in a wheel chair . He finds that the boy moves the wheel with his hands. Tom looks at him carefully and is surprised to see that the boy has no feet. He looks at his own feet. "It's much better to be without shoes than without feet." he thinks. There is no reason for him to feel so sorry and sad. He smiles and thinks he is happier. From the story we can know that Tom _ .
