　　【答案及详解】

　　答案：CCCDA

　　1 C。事实细节题。第一段提到了影响视幅的因素：不同的人，不同的阅读目的，对材料的熟悉程度，光线，疲劳。C“一组词的长度”不是能影响视幅的因素，是本题的答案。

　　2 C。观点态度题。作者在第二段第二句提到，眼睛训练课程只注重了阅读的视觉因素。倒数第二句书哦，阅读要求具备理解单词间关系的能力。因此选项C“阅读需要大脑的深度参与”正确。作者没有否定阅读的视觉因素的必要性，但是也没有说读者应该练习拓宽视幅，加快阅读速度。所以AB两项都不正确。作者没有对大脑和眼睛在阅读过程中的重要性进行对比，所以不选D

　　3 C。 作者在这句话中先是肯定了那些阅读练习提高看单词的能力，然后提出了有效阅读概念。后面句中还指出，有效阅读需要的是理解单词间的联系的能力。所以作者的意思应该是那些(训练眼睛的)阅读练习对与有效的阅读无益。B与文章相反。D句是蕴涵其中一个意思，却不是作者想表达的方向。

　　4 D。 第二段最后一句说，眼睛训练对于帮助读者阅读连贯文章无益，所以D是错的，是本题答案。

　　5 A。 参考前面的结构剖析，作者写本文的主要目的是对那些只关注阅读的视觉因素的阅读能力课程进行批判，所以答案应该是A。

　　Unless we spend money to spot and prevent asteroids (小行星) now, one might crash into Earth and destroy life as we know it, say some scientists.

　　Asteroids are bigger versions of the meteoroids (流星) that race across the night sky. Most orbit the sun far from Earth and don’t threaten us. But there are also thousands of asteroids whose orbits put them on a collision course with Earth.

　　Buy $50 million worth of new telescopes right now. Then spend $10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we’ll have a way to change its course.

　　Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn’t be cheap.

　　Is it worth it? Two things experts consider when judging any risk re: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare—but if one did fall, it would be the end of the world. “If we don’t take care of these big asteroids, they’ll take care of us,” says one scientist. “It’s that simple.”

　　The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.

　　21. What does the passage say about asteroids and meteoroids?

　　A) They are heavenly bodies different in composition.

　　B) They are heavenly bodies similar in nature.

　　C) There are more asteroids than meteoroids.

　　D) Asteroids are more mysterious than meteoroids.

　　22. What do scientists say about the collision of an asteroid with Earth?

　　A) It is very unlikely but the danger exists.

　　B) Such a collision might occur once every 25 years.

　　C) Collisions of smaller asteroids with Earth occur more often than expected.

　　D) It’s still too early to say whether such a collision might occur.

　　23. What do people think of the suggestion of using nuclear weapons to alter the courses of asteroids?

　　A) It sounds practical but it may not solve the problem.

　　B) It may create more problems than it might solve.

　　C) It is a waste of money because a collision of asteroids with Earth is very unlikely.

　　D) Further research should be done before it is proved applicable.

　　24. We can conclude from the passage that ________.

　　A) while pushing asteroids off course nuclear weapons would destroy the world

　　B) asteroids racing across the night sky are likely to hit Earth in the near future

　　C) the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetime

　　D) workable solutions still have to be found to prevent a collision of asteroids with Earth

　　25. Which of the following best describes the author’s tone in this passage?

　　A) Optimistic. B) Critical. C) Objective. D) Arbitrary.

　　21. B 22. A 23. B 24.D 25. C
