Question

【題目】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（縫紉）, become nearsighted. Then they have to wear glasses in order to see distant things clearly.

People who are farsighted（遠(yuǎn)視的）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, 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】本文敘述了人們看不清東西的集中情況：近視，遠(yuǎn)視以及其他方面的一些問(wèn)題。近視的人只能看清楚離他們眼睛很近的東西，要想看清遠(yuǎn)處的東西就要戴眼鏡。遠(yuǎn)視的人能看清遠(yuǎn)處的東西，離他們近的東西看不清楚，需要戴眼鏡才能看清。眼睛形狀不正確，也看不清東西，需要戴眼鏡來(lái)糾正。還有人是因?yàn)榈昧税變?nèi)障而看不清，需要去除眼睛上的障礙物。再有，就是晚上人們因?yàn)樘旌诙�看不清楚�?/span>

【1】細(xì)節(jié)理解題。由“It is only when we cannot see perfectly that we come to see how important our eyes are.”可知只有當(dāng)我們不能很清楚的看東西的時(shí)候，我們才會(huì)意識(shí)到眼睛的重要性。故選B。

【2】細(xì)節(jié)理解題。由“Many people who do a lot of close work, such as writing, reading and sewing（縫紉）, become nearsighted.”可知很多像做寫作，讀書(shū)，縫紉這樣近距離工作的人都會(huì)變得近視。A. tailor 裁縫 B. Doctor醫(yī)生 C. guard 獄警 D. painter畫(huà)家，A符合題意，故選A。

【3】細(xì)節(jié)理解題。由“it is possible to operate on the cataracts and remove them.”可知白內(nèi)障可以做手術(shù)去除。故選C。

【4】細(xì)節(jié)理解題。由“People who are farsighted（遠(yuǎn)視的）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.”可知遠(yuǎn)視眼的人讀書(shū)有困難，除非他們把書(shū)放在一臂遠(yuǎn)，他們看不清近處的東西。所以遠(yuǎn)視的人不戴眼鏡就不能做大量近距離的工作。故選A。

【5】細(xì)節(jié)理解題。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.”在你逐漸適應(yīng)黑夜之后，如果你用側(cè)面看而不是用眼中間看，效果會(huì)更好。可知稍微朝著不同的方向看會(huì)更好。故選D。
