　　【答案及詳解】

　　答案：CCCDA

　　1 C。事實細(xì)節(jié)題。第一段提到了影響視幅的因素：不同的人，不同的閱讀目的，對材料的熟悉程度，光線，疲勞。C“一組詞的長度”不是能影響視幅的因素，是本題的答案。

　　2 C。觀點態(tài)度題。作者在第二段第二句提到，眼睛訓(xùn)練課程只注重了閱讀的視覺因素。倒數(shù)第二句書哦，閱讀要求具備理解單詞間關(guān)系的能力。因此選項C“閱讀需要大腦的深度參與”正確。作者沒有否定閱讀的視覺因素的必要性，但是也沒有說讀者應(yīng)該練習(xí)拓寬視幅，加快閱讀速度。所以AB兩項都不正確。作者沒有對大腦和眼睛在閱讀過程中的重要性進行對比，所以不選D

　　3 C。 作者在這句話中先是肯定了那些閱讀練習(xí)提高看單詞的能力，然后提出了有效閱讀概念。后面句中還指出，有效閱讀需要的是理解單詞間的聯(lián)系的能力。所以作者的意思應(yīng)該是那些(訓(xùn)練眼睛的)閱讀練習(xí)對與有效的閱讀無益。B與文章相反。D句是蘊涵其中一個意思，卻不是作者想表達的方向。

　　4 D。 第二段最后一句說，眼睛訓(xùn)練對于幫助讀者閱讀連貫文章無益，所以D是錯的，是本題答案。

　　5 A。 參考前面的結(jié)構(gòu)剖析，作者寫本文的主要目的是對那些只關(guān)注閱讀的視覺因素的閱讀能力課程進行批判，所以答案應(yīng)該是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 (毀滅性的) 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
