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 are: 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 course 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

除非我们花钱去侦察和防止小行星(小行星)现在,你可能要坠毁到地球,毁坏人们所理解的生命,说一些科学家.
小行星非常大的版本的流星,(流星横跨夜晚的天空.大多数绕太阳轨道远离地球和不要威胁我们.但同样也有成千上万的小行星的把他们轨道地物体撞上地球.
美元购买价值5000万美元新型天文望远镜就可以了.然后我花一年1千万美元的未来25年内找到大部分的太空岩石.我们发现一个最致命的一次,科学家们说,我们会有一种方法来改变它的课程.
一些科学家支持小行星离了航线,推动拥有核子武器.但是成本不会变得便宜.
值得吗?审判时,有两件事情的专家们认为是:1)任何风险事件为大;2)多坏的后果如果事件的发生.专家们认为小行星大到足以摧毁很多有生命的每50万年才与地球相撞一次罢工.听起来很罕见,但如果某人对掉在什么东西上,这将是世界末日.“如果我们不小心的话,这些大小行星,他们会照顾我们,”有人说科学家.“就这么简单.”
治疗,却可能比先前的更利害了疾病.我们真的想要舰队核武器围坐在在地球上吗?“世界上有不害怕来自世界末日(毁灭性的)比和一个伟大的岩石核舰队反对它,说:”纽约时报文章.
21岁.这篇文章有什么说的小行星和流星吗?
他们都是天体不同的成分.
2)他们都是天体在性质上有类似处.
C)比流星小行星.
D)小行星是比流星更神秘.

B)这样的碰撞可能发生的一次每25年.
C)碰撞较小的小行星与地球更常出现超过预期.
D)仍然太早说是否这样的碰撞可能发生.
23日.的人怎么看的建议来改变使用核武器小行星过程中吗?
一)听起来实用,但可能不能解决问题
B,它可能产生的问题多于可能会解决
