高中英語閱讀強化試題原文：

　　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(nèi)障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

　　When night falls, colours become fainter to the eye 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 see a small thing to one side of you, which seems to disappear if you turn you 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 cannot see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive(敏感的) in daylight, is not as sensitive as the sides of the eyes after dark.
