1、Blasts from the Past 1 Volcanoes were more destructive in ancient history. Not because they were bigger, but because the carbon they released wiped out life with greater ease. 2 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. 3 Wignall calculated the "killing efficiency" fｏｒthese volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size fｏｒsize, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals. 4 The Permian extinction, fｏｒexample, 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 8 per cent of all marine genera at the time, ａｎｄ　it took 5 million years far tire planet to recover. 5 Yet 60 million years ago in the late Palaeocene 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 at the end of the Cretaceous, 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid. 6 Wignall thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of C02 Ocean chemistry may also have played a role. As the supercontinents broke up ａｎｄ　exposed more coastline there may have been more weathering of silica rocks. This would have encouraged the growth of phytoplankton in the oceans, increasing the amount of C02 absorbed from the atmosphere. 7 Vincent Courtillot, directｏｒof the Paris Geophysical Institute in France, says that Wignall\'s 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 fasted. ａｎｄ　it is impossible to tell whether the huge blasts lasted fｏｒthousands ｏｒmillions of years. 8 Courtillot 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 ｏｒsulphur dioxide emissions. Paragraph 4____ 【单选题】

A.Killing Power of Ancient Volcanic Eruptions

B.Association of Mass Extinction with Volcanic Eruption

C.Calculation of the Killing Power of Older Eruptions

D.A Mass Extinction

E.Volcanic Eruptions That Caused No Mass Extinction

F.ccounting fｏｒthe Killing Power of Older Eruptions

正确答案:D

答案解析:A mass extinction意为“一次大量的生物灭绝”。文章的第一句话是这么说的：Volcanoes were more destructive in ancient history. 火山在远古更具毁灭性。这是文章的基本论点或基本假设。假设是需要证明的。第二、三段其实都是在证明这一基本假设。第三段还有这样一句话： older eruptions were at least 10 times as effective at wiping out life as their more recant rivals. 这个命题虽然可用来支持文章的基本假设，但是它本身也需要证明。第四段讲的是二叠纪生物灭绝，这是发生在远古的大规模的生物灭绝。这是一个证据，因此D是正确的。

2、 More Than 8 Hours Sleep Too Much of a Good Thing 1 Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences. 2 Investigators at the University of California in San Diego found that people who clock up 9 ｏｒ10 hours each weeknight appear to have more trouble falling ａｎｄ　staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep arid feeling refreshed after a night\'s sleep than 8-hour sleepers. 3 These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night\'s rest may not need to ｓｅｔaside more than 8 hours a night. He added that "it might be a good idea" fｏｒpeople who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. 4 Previous studies have shown the potential dangers of chronic shortages of sleep, fｏｒinstance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5 Fｏｒthe current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week ａｎｄ　whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning ａｎｄ　being unable to fall hack to sleep, ａｎｄ　having fatigue interfere with day-to-day functioning. 6 Kripke found that people who slept between 9 ａｎｄ　10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bad. "It stands to reason that if a person spends too long a time in bed, then they\'ll spend a higher percentage of time awake," he said. Paragraph 4____ 【单选题】

A. Kripke\'s Research Tool

B.Dangers of Habitual Shortages of Sleep

C. Criticism on Kripke\'s Report

D.A Way of Overcoming Insomnia

E.Sleep Problems of Long ａｎｄ　Shoat Sleepers

F.Classification of Sleep Problems

正确答案:B

答案解析:第四段阐述了长期睡眠不足所带来的严重后果。

3、Youth Emancipation in SpainThe Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest.Around 55 percent of people aged 18 ～ 34 in Spain still sleep in their parents\' home, says the latest report from the country\'s state - run Institute of Youth.To coax (劝诱) young people from their homes, the Institute started a "Youth Emancipation(解放)" programme this month. The programme offers guidance in finding rooms ａｎｄ　jobs.Economists blame young people\'s family dependence on the precarious (不稳定的) labour market ａｎｄ　increasing housing prices. Housing prices have risen 17 percent a year since 2000.Cultural reasons also contribute to the problem, say sociologists (社会学家). Family ties in south Europe (Italy, Portugal ａｎｄ　Greece) are stronger than those in middle ａｎｄ　north Europe, said Spanish sociologist Almudena Moreno Minguez in her report "The Late Emancipation of Spanish Youth: Key fｏｒUnderstanding"."In general, young people in Spain firmly believe in the family as the main body around which their private life is organized," said Minguez.In Spain, especially in the countryside, it is not uncommon to find entire groups of aunts, uncles, cousins, nieces ａｎｄ　nephews (外甥／侄子) all living on the same street. They regularly get together fｏｒSunday dinner.Parents tolerance is another factor. Spanish parents accept late - night partying ａｎｄ　are wary of setting bedtime rules."A child can arrive home at whatever time he wants. If parents complain he\'ll put up a fight ａｎｄ　call the father a fascist," said Jose Antonio Gomez Yanez, a sociologist at Carlos Ill University in Madrid.Mothers willingness to do children\'s household chores (家务) worsens the problem. Dionisio Masso, a 60 - year - old in Madrid, has three children in their 20s, The eldest 28, has a girlfriend ａｎｄ　a job. But life with mum is good."His mum does the wash ａｎｄ　cooks fｏｒhim, in the end, he lives well," Masso said.The "Youth Emancipation" programme aims at helping young people ______.【单选题】

A.live in an independent way

B.fight fｏｒfreedom

C.fight against social injustice

D.get rid of family responsibilities

正确答案:A

答案解析:本题难度不大，虽然题干词汇在第三段出现，但只要认真从文章第一段读起，找到答案依据不难。答案依据在第一段，it has to decided to help them to leave the nest，帮助年轻人独立地生活，所以答案是A。

4、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people ｏｒsingles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit fｏｒsingles ｏｒunhappily married people, according to the study."There seems to be some unique health benefits from marriage. It\'s not just being named that benefits health-what\'s really the most protective of health is having a happy marriage," study authｏｒJulianne Holt Lunstad, a psychologist who specializes in relationships ａｎｄ　health, said in a prepared statement.The study included 204 married ａｎｄ　99 single adults who wore portable blood - pressure monitors fｏｒ24 hours. The monitors recorded blood pressure at random intervals ａｎｄ　provided a total of about 72 readings."We wanted to capture participants\' blood pressure doing whatever they normally do in everyday life. Getting one ｏｒtwo readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people."Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.The study was published in the March 20 issue of the journal Annals (年刊) of Behavioral Medicine.The study also found that unhappily married adults have higher blood pressure than ____ happily married ａｎｄ　single adults.Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet ａｎｄ　having regular doctｏｒvisits. People in happy marriages also have a source of emotional support, she said. 【单选题】

A.nor

B.both

C.neither

D.either

正确答案:B

答案解析:本题难度不大，考查词义辨析，考查both的用法。文章此处是说“研究表明婚姻不幸福的成年人比婚姻幸福和单身的成年人血压都高”，答案是B。

5、SemcoAt 21, Ricardo Semler became boss of his father-s business in Brazil, Semco, which sold parts fｏｒships. Semler Juniｏｒworked like a madman, from 7:30 am. , until midnight every day. One afternoon, while touring a factory in New York, he collapsed. The doctｏｒwho treated him said, "There\'s nothing wrong with you. But if you continue like this, you\'ll find a new home in our hospital." Semler got the message. He changed the way he worked. In fact, he changed the way his employees worked too.He let his workers take more responsibility so that they would be the ones worrying when things went wrong. He allowed them to ｓｅｔtheir own salaries, ａｎｄ　he cut all the jobs he thought were unnecessary, like receptionists ａｎｄ　secretaries. This saved money ａｎｄ　brought more equality to the company. "Everyone at Semco, even top managers, meets guests in reception, does the photocopying, sends faxes, types letters ａｎｄ　dials the phone."He completely reorganized the office, instead of walls, they have plants at Semco, so bosses can\'t shut themselves away from everyone else. ａｎｄ　the workers are free to decorate their workspace as they want. As fｏｒuniforms, some people wear suits ａｎｄ　others wear T - shirts.Semler says, "We have a sales manager named Rubin Agater who sits there reading the newspaper hour after hour. He doesn\'t even pretend to be busy. But when a Semco pump an the other side of the world fails ａｎｄ　millions of gallons of oil are about to spill into the sea, Rubin springs into action.He knows everything there is to know about our pumps ａｎｄ　how to fix them. That\'s when he earns his salary. No one cares if he doesn\'t look busy the rest of the time."Semco has flexible working hours, the employees decide when they need to arrive at work, The employees also evaluate their bosses twice a year. Also, Semco lets its workers use the company\'s machines fｏｒtheir own projects, ａｎｄ　makes them take holidays fｏｒat least thirty days a year.It sounds perfect, but does it work? The answer is in the numbers. In the last six years, Semco\'s revenues have gone from $ 35 million to $ 212 million. The company has grown from eight hundred employees to 3,000, Why?Semler says it\'s because of "peer pressure". Peer pressure makes everyone work hard fｏｒeveryone else. ____ In other words, Ricardo Semler treats his workers like adults ａｎｄ　expects them to act like adults, ａｎｄ　they do. 【单选题】
