Question

18．The world is not coming to an end on December 21，2012，the US space agency insisted Monday in a rare campaign to dispel widespread rumors fueled by the Internet and a new Hollywood movie．
The latest big screen offering from Sony Picture，2012，arrives in theaters on Friday，with a 200-million-dollar production about the end of the world supposedly based on myths （虛構(gòu)的故事） backed by the Mayan calendar．It is claimed that the end of time will come as a Planet X-or Nibiru-heads toward or collides with the Earth．
Some websites accuse NASA of hiding the truth on the planet's existence，but the US space agency denounced such stories as an"Internet hoax（惡作�。�"．"There is no factual basis for these claims，"NASA said in a question and answer posting on its website．"If such a collision were real，astronomers would have been tracking it for at least the past decade，and it would be visible by now to the naked eye．Obviously，it does not exist．Credible scientists worldwide know of no threat associated with 2012，"it insisted．"After all，our planet has been getting along just well for more than four billion years，"added NASA．
There is another planet，Eris，floating in space．But the small planet similar to Pluto will remain safely fixed in the outer solar system and it can come no closer than four billion miles to the Earth，according to NASA．
Initial theories set the disaster for May 2003，but when nothing happened the date was moved forward to the winter in 2012 to coincide with the end of a cycle of the ancient Mayan calendar．
NASA insisted the Mayan calendar in fact does not end on December 21，2012，as another period begins immediately afterward．
And even if the planets were to line up as some have forecast，the effect on our planet would be"negligible"，NASA said．
"And while comets and asteroids （小行星） have always hit the Earth，big hits are very rare，"NASA noted．The last major impact was believed to be 65 million years ago，resulting in the end of dinosaurs．
"We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs，"the space agency said．

C．NASA                             D．An Indian calendar

Answer 1

分析 本文主要講的是好萊塢災(zāi)難大片《2012》使網(wǎng)絡(luò)上盛傳的"2012年12月21日為世界末日"這一所謂的瑪雅預(yù)言再次進(jìn)入人們的視野．為此，美國(guó)宇航局重申，2012年12月21日并不是世界末日，傳言中的X星球?qū)⑴c地球相撞也并不屬實(shí)．

解答 49．B．細(xì)節(jié)理解題．根據(jù)第一段中"to dispel widespread rumors fueled by the Intermet and a new Hollywood movie"可知因特網(wǎng)和一部好萊塢新片對(duì)傳播世界末日的謠言起到了推波助瀾的作用．故選B．
50．A．細(xì)節(jié)理解題．根據(jù)第二段第一句"about the end of the world supposedly based on myths"可知《2012》這部電影是關(guān)于世界末日的．根據(jù)文章內(nèi)容可先排除D項(xiàng)；由第二段中based on myths（虛構(gòu)的故事）可知B項(xiàng)錯(cuò)誤；由宇航局的講話"There is no factual basis for these claims，"可推出C項(xiàng)錯(cuò)誤．故選A．
51．D．推理判斷題．根據(jù)文中第一段中"the US space agency insisted Monday in a rare campaign to dispel widespread rumors"可知謠言傳播之廣以至于美國(guó)宇航局不得不出來(lái)辟謠，由此可見(jiàn)事態(tài)嚴(yán)重，故可判斷謠言有可能造成了一些人的恐慌．故選D．
52．B．主旨大意題．本文主要講美國(guó)宇航局駁斥"2012年12月21日是世界末日"的謠言．故B項(xiàng)為最佳標(biāo)題．故選B．

點(diǎn)評(píng) 本文考察同學(xué)們新聞報(bào)道類閱讀理解，此類閱讀的關(guān)鍵在于了解發(fā)生了什么新聞．另外此類閱讀涉及面頗廣，可涉及：時(shí)事熱點(diǎn)，生活，科技，軍事，抗震救災(zāi)，世界大事等等諸多方面．同學(xué)們?cè)诖祟愵}是應(yīng)該注意找尋關(guān)鍵字，有時(shí)并不需要閱讀全文．這類材料命題點(diǎn)往往落在事實(shí)細(xì)節(jié)上．
