Question

【題目】 When we can see well, we do not think about our eyes often. It is only when we cannot see perfectly that we come to know how important our eyes are. People who are nearsighted can see things that are very close to their eves. Many people who do a lot of close work, such as writing and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly. People who are farsighted face 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 take them away.

When night falls, colours become fainter(黯淡) to the eves and finally disappear. After your eyes have got used to the dark, you can see better if you use the side of your eyes rather than the centres. Sometimes, after dark, you 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 cannot see it any more, and they believe they were mistaken. However, this happens because the centre of the eye, which is very sensitive(敏感的) in daylight, is not as sensitive as the sides of the eye after dark.

【解析】

眼睛是我們身體上很重要的一個(gè)器官，人們的眼睛會(huì)有很多問(wèn)題，如近視、遠(yuǎn)視、白內(nèi)障等，這篇短文給我們介紹了關(guān)于我們的眼睛的一些知識(shí)。

【1】細(xì)節(jié)理解題。根據(jù)短文第一段It is only when we cannot see perfectly that we come to know how important our eyes are.可知，只有當(dāng)我們的眼睛看不清楚東西的時(shí)候，我們才知道眼睛的重要。由此可知應(yīng)選B。

【2】推理判斷題。根據(jù)短文第一段中Many people who do a lot of close work, such as writing and reading, become nearsighted.可知，經(jīng)常做閱讀、寫作等近距離工作的人，容易近視。選項(xiàng)中policeman是警察；doctor是醫(yī)生；football player是足球運(yùn)動(dòng)員；guard是保安。在這四個(gè)選項(xiàng)中，醫(yī)生用眼比較多，故應(yīng)選B。

【3】細(xì)節(jié)理解題。根據(jù)短文第一段People who are farsighted face 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.可知，遠(yuǎn)視的人看不清楚近的事物，他們需要戴眼鏡。由此可知應(yīng)選A。

【4】推理判斷題。根據(jù)短文第三段Sometimes, after dark, you 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.，天黑后，你會(huì)看到身體一側(cè)有小東西。如果你把頭轉(zhuǎn)向它，它似乎就會(huì)消失。所以在晚上想要看清楚一個(gè)小東西，最好向有點(diǎn)不同的方向看。故應(yīng)選D。

【5】推理判斷題。根據(jù)第二段第一句話Other people do not see clearly because their eyes are not exactly the right shape.可知，有些人看不清楚是因?yàn)樗麄兊难劬π螤钣袉?wèn)題。故C選項(xiàng)符合文意，選C。
