遼寧高考英語閱讀練習題原文

　　Other people do not see clearly because their eyes are not exactly the right shape. This, too,can be corrected by glasses. Some people‘s eyes become cloudy because of cataracts(白內障).Long ago these people often became blind. Now, however, it is possible to operate on thecataracts and remove them.

　　When night falls, colours become fainter to the eye and finally disappear. After your eyeshave grown used to the dark, you can see better if you use the sides of your eyes rather thanthe centers. Sometimes, after dark, you see a small thing to one side of you, which seems todisappear if you turn you head in its direction. This is because when you turn your head, youare looking at the thing too directly. Men on guard duty sometimes think they see somethingmoving to one side of them. When they turn to look straight at it, they cannot see it any more,and they believe they were mistaken. However, this mistake happens because the center of theeye, which is very sensitive(敏感的) in daylight, is not as sensitive as the sides of the eyesafter dark.
