2019中考英语选练（8）（阅读理解）AWhen we can see well, we dont think about our eyes very often. It is only when we can not see perfectly that we come to see how important our eyes are.People who are nearsighted can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant things clearly.People who are farsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty reading a book unless they hold it at arms length. If they want to do much reading, they must get glasses, too.Other people do not see clearly because their eyes are not exactly the right shape. This, too, can be corrected by glasses. Some peoples eyes become cloudy because of cataracts（白内障）. Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.When night falls, colures become fainter to the eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the sides of your eyes rather than the centers. Sometimes, after dark, you can see a small thing to one side of you, which seems to disappear if you turn your head in its direction. This is because when you turn your head, you are looking at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they cant see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark.1.

Now science fiction has become science fact. For the first time, scientists have made a robot that can keep on working. Scientists from Cornell University made the robot, which looks like an animal with four legs.Until now, even the most perfect robot is almost certain to break down when it is damaged. That is because its computer inside simply doesnt know how to make the robot work after its shape has changed. To deal with this problem, the scientists put a “brain” into the robot that can read how the robot is working. With it , the computer can then know the robots shape at any moment.“The new technology has developed in robot-making,” scientists say. It may someday help scientists create better man-made arms and legs and give new freedom（自由）to people who lose them. It might also help scientists understand how people and animals know their own sense of place in space.“It has been difficult to design robots that can work well when the environment changes or when its damaged,” says Olaf Sporns of Indiana University in the US. “With this work, we are nearer to solving this problem.”( ) 1. It has become a science fact that _.
