  Older Volcanic Eruptions

  Volcanoes were more destructive in ancient history, not because they were bigger, but because the carbon dioxide they released wiped out life with greater ease.

  Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over the past 300 million years coincided with huge formations of volcanic rock. To his surprise, the older the massive volcanic eruptions were, the more damage they seemed to do. He calculated the "killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size for size, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.

  The Permian extinction, for example, which happened 250 million years ago, is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe. Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide. The global warming that followed wiped out 80 per cent of all marine genera at the time, and it took 5 million years for the planet to recover. Yet 60 million years ago, there was another huge amount of volcanic activity and global warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years. "The most recent ones hardly have an effect at all," Wignall says. He ignored the extinction which wiped out the dinosaurs 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid. He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO2.

  Vincent Courtillot, director of the Paris Geophysical Institute in France, says that Wignalls idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they lasted. And it is impossible to tell whether the huge blasts lasted for thousands or millions of years. He also adds that it is difficult to estimate how much lava prehistoric volcanoes produced, and that lava volume may not necessarily correspond to carbon dioxide emissions.

  远古火山喷发

  古代的火山更具杀伤力,不是因为它们更大,而是因为它们释放出来的二氧化碳更容易把人杀死。

  来自里兹大学的Paul Wignall正在调查火山爆发和大规模物种灭绝之间的联系。不是所有的火山都会造成大量动物死亡。但在过去的三亿年间,巨大的火山岩石的形成都伴随着大规模种族灭绝。让他惊奇的是,远古的火山造成的破坏更大。他通过比较火山释放出的熔岩的体积与杀死生命的比例计算这些火山的杀伤效力。他发现,体积相同的情况下,老远古火山要比近期火山的杀伤力大十倍。

  例如,发生在两亿五千年前的二叠纪物种灭绝就与西伯利亚的火山爆发发生在同一时期。当时的火山岩大约覆盖了西欧那么大的面积。当时火山释放出了大约100亿吨梯恩梯的二氧化碳,随之而来的全球变暖杀死了80%的海洋生物。500万年以后,地球才恢复到原来的状态。然而,6000年前,火山大规模爆发,以及而后的全球变暖并没有带来种族灭绝。一些动物确实消失了,但几万年以后,地球又恢复到以前的水平。“最近的一次火山爆发基本上没带来什么影响。”Wignall称。他并没有将650万年前的恐龙灭绝计算在内,因为大部分的科学家认为那是有小行星撞击地球所引起的。他认为,远古火山之所以杀伤力大是因为近期的生物能够更好的适应二氧化碳含量上升。

  法国巴黎地理研究所的所长Vincent Courtillot称Wignall的观点很具争议性,并且很难做出这样的计算。他指出火山爆发的杀伤力是由其持续长度所决定的。并且很难知道是否大规模爆发会持续上百万年。他补充道,很难计算远古火山灰喷发多少火山岩,并且火山岩的数量也不一定和二氧化碳释放数量相一致。

  词汇:

  dioxide n. 二氧化物

  lava n. 熔岩

  Permian adj. 二叠纪

  gigaton n. 十亿吨梯恩梯

  genera n. 种类

  dinosaurs n. 恐龙

  asteroid n. 小行星

  注释:The Permian extinction 二叠纪物种灭绝

  练习:

  1. Why did older volcanic eruptions do more damage than more recent ones?

  A) Because they killed off life more easily.

  B) Because they were brighter.

  C) Because they were larger.

  D) Because they were hotter.

  2. How did Wignall calculate the killing power of those older volcanic eruptions?

  A) By estimating how long they lasted.

  B) By counting the dinosaurs they killed.

  C) By studying the chemical composition of lava.

  D) By comparing the proportion of life wiped out with the volume of lava produced.

  3. When did dinosaurs become extinct?

  A) 300 million years ago.

  B) 250 million years ago.

  C) 60 million years ago.

  D) 65 million years ago.

  4. What can be inferred from paragraph 3 concerning dinosaurs?

  A) They were killed off by an asteroid.

  B) They died of drastic climate change.

  C) They were wiped off by a volcanic eruption.

  D) The cause of their extinction has remained a controversial issue.

  5. What is the main thesis of the article?

  A) Volcanic eruptions are not always deadly.

  B) Older volcanic eruptions were more destructive.

  C) Carbon dioxide emissions often give rise to global warming.

  D) It is not easy to calculate the killing power of a volcanic eruption.

  答案与题解:

  1.A 问题问的是:为什么远古的火山爆发比近期的火山爆发破坏性更大?第一段是这么说的:古代的火山更具破坏力,不是因为它们更大,而是因为它们释放出的二氧化碳更能容易地毁灭生命。

  2.D 问题问的是:Wignall是如何计算出远古火上爆发的杀伤力的?答案在第二段。第二段有这样一句话:He calculated the "killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced.他通过比较火山释放出的熔岩的体积与杀死生命的比例计算这些火山的杀伤效力。

  3.C 问题问的是:恐龙是什么时候灭绝的?答案在第三段。其中有这么一句话:He ignored the extinction which wiped out the dinosaurs 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid.他没有提及6千5百万年前恐龙的灭绝是因为许多科学家相信恐龙的灭绝是受一颗小行星的影响。

  4.D 问题问的是:第三段还可以推导出有关恐龙的什么样的信息?在讨论第三题的答案时,我们已经注意到了,Wignall没有提6千5百万年前恐龙的灭绝是否跟火山爆发有关是因为许多科学家相信恐龙的灭绝是受一颗小行星的影响。这就说明,关于恐龙灭绝的原因在科学家之间是有分歧的。

  5.B 问题问的是:文章的主要论点是什么?答案在文章的第一句:Volcanoes were more destructive in ancient history, ...(古代火山更具破坏力)。

  Adult Education

  Voluntary learning in organized courses by mature men and women is called adult education.Such education is offered to make people able to enlarge and interpret their experience as adults.Adults may want to study something which they missed in earlier schooling,get new skills or job training,find out about new technological developments,seek better self-understanding,or develop new talents and skills.

  This kind of education may be in the form of self-study with proper guidance through the use of libraries,correspondence course,or broadcasting.It may also be acquired collectively in schools and colleges,study groups,workshops,clubs,and professional associations.

  Modern adult education for large numbers of people started in the 18th and 19th centuries with the rise of the Industrial Revolution.Great economic and social changes were taking place: people were moving from rural areas to cities; new types of work were being created in an expanding factory system.These and other factors produced a need for further education and re-education of adults.

  The earliest programs of organized adult education arose in Great Britain in the 1790s,with the founding of an adult school in Nottingham and a mechanics institute in Glasgow.The earliest adult education institution in the United States was founded by Benjamin Franklin and some friends in Philadelphia in 1727.

  People recognize that continued learning is necessary for most forms of employment today.For example,parts of the adult population in many countries find it necessary to take part in retraining programs at work of even to learn completely new jobs.Adult education programs are springing up constantly to meet these and other needs.

  练习:

  1.Paragraph 2__________.

  2.Paragraph 3__________.

  3.Paragraph 4__________.

  4.Paragraph 5__________.

  A Necessity for developing adult education

  B Early days of adult education

  C Ways of receiving adult education

  D Growth of adult education

  E Institutions of adult education

  F Definition of adult education

  5.Some adults want to learn _______________.

  6.There are various forms of adult education,including ____________.

  7.Adult education has been made necessary ___________.

  8.The earliest organized adult education _______________.

  A by social and economic changes

  B guided self-study and correspondence courses

  C by studying together with children

  D what they did not manage to learn earlier

  E dates back to the eighteenth century

  F mass production

  答案:C A B D D B A E
