Question

【题目】When we can see well, we do not think about our eyes very often. It is only when we cannot 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（缝纫）, become nearsighted. Then they have to wear glasses in order to see distant things clearly.

People who are farsighted（远视的）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 arm’s 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 people’s 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, colors 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.

【解析】本文叙述了人们看不清东西的集中情况：近视，远视以及其他方面的一些问题。近视的人只能看清楚离他们眼睛很近的东西，要想看清远处的东西就要戴眼镜。远视的人能看清远处的东西，离他们近的东西看不清楚，需要戴眼镜才能看清。眼睛形状不正确，也看不清东西，需要戴眼镜来纠正。还有人是因为得了白内障而看不清，需要去除眼睛上的障碍物。再有，就是晚上人们因为天黑而看不清楚。

【1】细节理解题。由“It is only when we cannot see perfectly that we come to see how important our eyes are.”可知只有当我们不能很清楚的看东西的时候，我们才会意识到眼睛的重要性。故选B。

【2】细节理解题。由“Many people who do a lot of close work, such as writing, reading and sewing（缝纫）, become nearsighted.”可知很多像做写作，读书，缝纫这样近距离工作的人都会变得近视。A. tailor 裁缝 B. Doctor医生 C. guard 狱警 D. painter画家，A符合题意，故选A。

【3】细节理解题。由“it is possible to operate on the cataracts and remove them.”可知白内障可以做手术去除。故选C。

【4】细节理解题。由“People who are farsighted（远视的）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 arm’s length.”可知远视眼的人读书有困难，除非他们把书放在一臂远，他们看不清近处的东西。所以远视的人不戴眼镜就不能做大量近距离的工作。故选A。

【5】细节理解题。由“ 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.”在你逐渐适应黑夜之后，如果你用侧面看而不是用眼中间看，效果会更好。可知稍微朝着不同的方向看会更好。故选D。
