1、2019中考英语选练（8）（阅读理解）AWhen we can see well, we dont think about our eyes very often. It is only when we can not 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

2、 writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant things clearly.People who are farsighted 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 arms length.

3、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 peoples eyes become cloudy because of cataracts（白内障）. Long ago these people often became blind. Now, however, i

4、t is possible to operate on the cataracts and remove them.When night falls, colures become fainter to the eyes 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 can see a small

5、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

6、cant see it any more, and they believe they were mistaken.

21、ude potatoes, corn, vegetable oil and bananas.

According to The Wall Street Journal, it takes 1,000 years for c

22、ommon plastic bags to break down. But an EnviGreen bag can naturally break down in less than 180 days. It also breaks down in less than a day in water, and in about 15 seconds in boiling water.

27、种新型塑料袋,这种塑料袋不仅对环境没有任何危害,而且还可以食用。1.B细节理解题。根据第一段倒数第二句话“They bring no harm to the environment.”可知,这种塑料袋对环境无害,故选项B“它对环境有一些害处”是不正确的表述。2.B主旨大意题。通读第二段内容可知,该段主要介绍了Hedge研制这种环保塑料袋的过程,故选B。3.A推理判断题。根据第三段第一句“Although an EnviGreen bag is about 35 percent more expensive than a common plastic bag, it has many advantages.”可知,这种环保塑料袋比普通的塑料袋贵35%。由此推测,选项A就是这种环保塑料袋的缺点。4.D推理判断题。根据最后一段的最后一句“Maybe the EnviGreen bag could be a solution to the world problem of plastic pollution.”可知,这种环保塑料袋的诞生,有可能会解决世界范围内的塑料污染问题。 故选D。 7
