Meteorite Impact（陨石撞击） and Dinosaur Extinction（恐龙的灭绝）

There is increasing evidence that the impacts of meteorites have had important effects on Earth, particularly in the field of biological evolution. Such impacts continue to pose a natural hazard（自然威胁） to life on Earth. Twice in the twentieth century, large meteorite objects are known to have collided with Earth.

越来越多的证据表明陨石撞击对地球造成的影响特别严重，尤其是生物进化领域。这种影响对地球上的生物来说，仍然是一种自然威胁。在20世纪，被人们所知悉的就有两次大型陨石撞地球的事件发生。

If an impact is large enough, it can disturb the environment of the entire Earth and cause an ecological catastrophe. The best-documented such impact took place 65 million years ago at the end of the Cretaceous period（白垩纪） of geological history. This break in Earth's history is marked by a mass extinction, when as many as half the species on the planet became extinct. While there are a dozen or more mass extinctions in the geological record, the Cretaceous mass

extinction has always intrigued （感兴趣）paleontologists （古生物学家）because it marks the end of the age of the dinosaurs. For tens of millions of years, those great creatures had flourished. Then, suddenly, they disappeared.

当撞击力度特别大时，陨石和地球的相撞将扰乱整个地球的环境，并引发一场生态灾难。记载最完整的这种灾难曾发生在6 500万年前，在地质历史阶段的白垩纪末期。地球历史上的那次重大灾难造成了大量生物死亡，当时多达一半的物种灭绝。根据地质史料记载，地球上有十几次甚至更多大型的物种灭绝，古生物学家一直对白垩纪大灭绝非常感兴趣，因为它标志着恐龙时代的结束。数千万年以来，那些庞大的生物繁盛活跃着；然后突然间，它们消失了。

The body that impacted Earth at the end of the Cretaceous period was a meteorite （陨石）with a mass of more than a trillion tons and a diameter （直径）of at least 10 kilometers. Scientists first identified this impact in 1980 from the worldwide layer of sediment（沉积） deposited from the dust cloud that enveloped the planet after the impact. This sediment layer is enriched in the rare metal iridium and other elements that are relatively abundant in a meteorite but very rare in the crust of Earth. Even diluted（削弱） by the terrestrial（陆地的） material excavated from the crater, this component of meteorites is easily identified. By 1990 geologists had located the impact site itself in the Yucat region of Mexico. The crater, now deeply buried in sediment, was originally about 200 kilometers in diameter.

将大量尘埃扬起至大气层中，尘埃降至地面后逐渐形成沉积岩，通过测量沉积岩的厚度，我们可以判断当时的大气中的尘埃约有100万亿吨。如此大量的物质存在于大气层中，将会完全阻隔了阳光的照射，于是地球一瞬间进入了一个持续数月之久的寒冷黑暗时期。据估计，爆炸过程还产生了大量的硝酸和被溶解的岩浆并喷出地球外，造成了大面积火灾，大部分的森林和草原被燃尽。这些环境灾难很可能就是包括恐龙在内的大规模物种灭绝的原因。

This impact released an enormous amount of energy, excavating a crater （火山口）about twice as large as the lunar crater Tycho. The explosion lifted about 100 trillion tons of dust into the atmosphere, as can be determined by measuring the thickness of the sediment layer formed when this dust settled to the surface. Such a quantity of material would have blocked the sunlight completely from reaching the surface, plunging （跳入）Earth into a period of cold and darkness that lasted at least several months. The explosion is also calculated to have produced vast quantities of nitric acid and melted rock that sprayed out over much of Earth, starting widespread fires that must have consumed most terrestrial forests and grassland. Presumably, those environmental disasters could have been responsible for the mass extinction, including the death of the dinosaurs.

白垩纪末期，撞击地球主体是一块巨大陨石，它的质量超过万亿吨，直径至少在10公里。1980年科学家通过研究撞击后形成的、覆盖地球表面

的尘雾沉积层，首次确认了这次撞击。该沉积层富含稀有金属铱和其他在陨石中含量较丰富但在地壳中却很稀有的元素。即便这些物质从陨石坑被挖掘出来后受到地球物质的稀释，其中的成分仍然很容易被鉴定出来。1990年，地质学家已经将那次撞击的地点定位于墨西哥的尤卡地区。现在被深埋于沉积物中的陨石坑，最初的直径为200公里左右。

Several other mass extinctions in the geological record have been tentatively identified with large impacts, but none is so dramatic as the Cretaceous event. But even without such specific documentation, it is clear that impacts of this size do occur and that their results can be catastrophic. What is a catastrophe for one group of living things, however, may create opportunities for another group. Following each mass extinction, there is a sudden evolutionary burst as new species develop to fill the ecological niches opened by the event.

这次撞击释放出了巨大的能量，凿出了一个约为月球第谷山口面积的两倍大的陨石坑。那场爆炸根据地质学记载，一些其他大批生物的灭绝也被初步认定认为与类似的撞击有关，但都没有白垩纪的那次触目惊心。不过即便是没有具体史料依据，这种规模的撞击显然发生过，并且带来了灾难性的后果。然而对于一个生物种群而言算是大灾难，却有可能给另一个种群创造了机会。每一次大灭绝过后，都会有新的物种爆炸式地进化去填补由灭绝造成的物种空缺。

Impacts by meteorites（陨石） represent one mechanism（机制） that could cause global catastrophes and seriously influence he evolution of life all over the

planet. According to some estimates（估计）, the majority of all extinctions of species may be due to such impacts. Such a perspective fundamentally changes our view of biological evolution. The standard criterion for the survival of a species is its success in competing with other species and adapting to slowly changing environments. Yet an equally important criterion is the ability of a species to survive random global ecological catastrophes due to impacts.

陨石撞击描绘了一个能够制造全球性的灾难的途径，这种灾难会对整个星球的生命体的进化带来重大影响。据估计，已经灭绝的所有物中，绝大部分都是由于这些撞击造成的。这种观点从根本上改变了我们对于生物进化的看法。一个物种生存的标准准则就是它成功地与其他物种对抗，并适应缓慢变化的环境。然而还有一个同等重要的准则就是，可以从随机的、由天体撞击造成的全球生态灾难中幸存。

Earth is a target in a cosmic（宇宙） shooting gallery, subject to random violent events that were unsuspected a few decades ago. In 1991 the United States Congress asked NASA to investigate the hazard posed today by large impacts on Earth. The group conducting the study concluded from a detailed analysis that impacts from meteorites can indeed be hazardous（有危险的）. Although there is always some risk that a large impact could occur, careful study shows that this risk is quite small.

几十年前，地球是宇宙射击场的一个靶子，容易受到未知的随机暴力事件的攻击。1991年美国国会要求美国国家航空航天局调查大型撞击对地

第一部分 选择题（共90分）

一、单项选择（共15小题；每小题1分, 满分15分）

【题文】1. Experiments of this kind ________ in both the U.S. and Europe long before the Second World War.

A. conducted B. was conducted C. had been conducted D. had conducted

【答案】【知识点】A11 动词的时态与语态

【答案解析】C。解析： the Second World War发生在过去，又因为before在…….之前，所以表示的是过去的过去，Experiments of this kind与conduct是被动关系，故用过去完成时的被动语态。句意：在二次世界大战之前这种实验在欧洲和美国进行得很好。

【题文】2. No scientists can exactly figure out what ________ happened ________ at that time, which caused the extinction of the dinosaurs.

A. on earth; on the earth B. on the earth; on earth

C. on earth; on earth D. on the earth; on the earth

【答案】【知识点】A6 连词与介词

【答案解析】A。解析：on earth:究竟,到底；on the earth在地球上；根据句意可知，第一个空是“究竟”，第二个空是“在地球上”句意：没有科学家能够准确找出在那时地球上究竟发生了什么事,导致恐龙的灭绝。

【技巧点拨】熟记两个短语的区别；on earth通常用在特殊疑问词后。

【典型总结】Who on earth told you that? 那件事究竟是谁告诉你的？What on earth will he get up to next? 下一步他究竟要耍什麽花样?

【题文】3. Food supplies in the earthquake area ________. We must act immediately before there’s none left.

A. are being run out B. are running out

C. have run out D. have been run out

【答案】【知识点】A11 动词的时态与语态

【答案解析】B。解析：run out用完；用尽；无被动形式，排除AD。根据后半句可知食物快用完了，故用现在进行时表将来。

【题文】4. The coat ________ thin but ________.

A. is worn„is dried easy B. wears„dries easily

C. has worn„has dried easy D. wears„dries easy

【答案】【知识点】A7 动词

【答案解析】B。第二个空修饰动词dry要用副词，排除ACD。第一个空wear作不及物动词"主动表被动"含义，表示主语的某种属性。解析：句意：外套穿着很薄，但是容易晒干。

【典型总结】英语中有些动词在形式上是主动的，含义上却是被动的，但是这些动词这样用时又不是不及物动词。常见的这类动词有：sell, wash, cook, wear, rite, look, open, shut, translate, read, last, cut等。His novel sells well.他的小说销路很好。 This cloth washes easily. 这种布很容易洗。His shoes have warn/wore through. 他的鞋子穿破了。

【题文】5. It’s illegal for a public official to ask people for gifts or money ________ favors to them.

A. in preference to B. in place of C. in agreement with D. in exchange for

【答案】【知识点】A6 连词与介词

【答案解析】D。解析：介词短语辨析in preference to“优先于”；in place of“代替”；in agreement with“与……一致”；in exchange for“交换”。 句意：对于一个公务员来说，为人们做点好事就向人们要物要钱是不合法的。

【题文】6. — Why are your eyes so red? You ________ well last night.

— Yes, I stayed up late writing a report.

A. mustn’t have slept B. can’t have slept C. couldn’t sleep D. might not sleep

【答案】【知识点】A10 情态动词与虚拟语气

【答案解析】B。解析：根据last night可判断出是对过去发生事情的猜测，要用情态动词+have done,故排除CD，根据why are your eyes so red？可以得出对方一定没有睡好。mustn’t（禁止，不准）can’t（不可能）can't have done（不可能做过）是must have done（一定做过）的否定形式。句意：你眼睛怎么这么红？你昨晚一定没睡好吧。---我熬夜写报告。

【题文】10. Miss Liu ________ as an accountant for 4 years in the company, and now she is a general manager of it.

A. served B. has served C. serves D. was serving

【答案】【知识点】A11 动词的时态与语态

【答案解析】A。解析：本题容易错选B项。但是现在完成时表示过去发生的事情对现在的影响，或者持续到现在。根据后半句现在她是这家公司的总经理，强调过去和现在的对比。句意：王小军在这家公司里做了四年的秘书，现在她是这家公司的总经理。

【题文】11. I suggest ________, considering the patient’s serious condition.

A. must send a doctor B. a doctor be sent for

C. a doctor to be sent D. sending a doctor for
