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 3____ 【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:C

答案解析:第三段的第一句话是这么说的：Wignall calculated the“killing efficiency”fｏｒthese valcanoes wignall计算了这些火山的“灭种效率”。killing power与killing efficiency意思差不多。killing power：灭种力。

2、Lower Body Fat Means Better Performance These days, fashion models ａｎｄ　pop stars are not the only people who have to watch their waistline. Football players who miss a few kicks ａｎｄ　let their belly hanging out a little too much are likely to be attacked by rabid fans ｏｒeven the president of a country. The latest football star to draw the attention of the "fat police" is Barcelona\'s Ronaldinho, 26. Last Friday, a Spanish sports daily published two photos of the Brazilian star without his shirt. One was taken in November 2003; the other was taken this month. In the most recent one, the star\'s waistline seems to have a little extra padding. Another Spanish sports daily published similar before-and-aider photos ａｎｄ　argued that the star has "lost his explosiveness ａｎｄ　velocity" ａｎｄ　is "worn out". The cause, according to the news paper, is his poｏｒphysical fitness. However, the player\'s coach, Frank Rijkaard, insists that he\'s satisfied with Ronaldinho\'s form ａｎｄ　fitness. ａｎｄ　after Barcelona\'s victory over Athletic Bibao on Sunday, Ronaldinho challenged photographers to take pictures of him when he took off his shirt. "I don\'t have anything to hide," he said. Fellow Brazilian ronaldo, 30, of Real Madrid, faced similar criticism before the 2006 World Cup. But the criticism didn\'t come from a bunch of sports reporters: It came from the president of Brazil. "So, what is it?" Brazil\'s President Luiz Inacio Lula da Silva asked the national soccer team\'s coach in his office last June, according to the Associated Press. "Is he [ronaldo]fat ｏｒnot?" "He is very strong, president," Carlos Alberto Parreira reportedly said at the time. "He is not that boy anymore. His body type has changed. " The game of footfall demands that players put as much emphasis on fitness as they can do on dribbling, passing ｏｒshooting. During a proper training regimen, football players normally follow a load-fatigue-recovery pattern. They push their body toward a higher mark of fitness ａｎｄ　experience a slight ａｎｄ　brief ｄｒｅｐin performance. Then they begin the recovery process, which will ideally carry their performance to an even higher plane. However, sometimes non-physical factors can influence a player\'s poｏｒfitness. In Ronaldinho\'s case, fｏｒinstance, people, often unnamed, have blamed everything from the pressure of contract negotiations to personal problems ａｎｄ　too many advertising commitments. Ronaldinho is a well-known Spanish star【单选题】

A.Right

B. Wrong

C.Not mentioned

正确答案:B

答案解析:句子说的是：Ronaldinho是一个知名度很高的西班牙球星，这个命题是错的。第二段有这样一个句子：Last Friday，a Spanish sports daily published two photos of the Brazilian star without his shirt. 这就说明Ronaldinho是巴西球星，而不是西班牙球星。

3、The Ideal HusbandScience now might be able to explain women\'s fascination with Brad Pitt\'s face ａｎｄ　George Clooney\'s eyes. Women seem to judge potential mate by how masculine their features are, new research shows. Men with square jaws ａｎｄ　well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face ａｎｄ　fuller lips are perceived as better long-term mates.In the study by Daniel Kruger at the US\'s University of Michigan, 854 subjects viewed a series of male head shots that had been digitally changed to exaggerate ｏｒminimize masculine traits. They then . answered questions about how they expected the men in the photos to behave.Most participants said that those with more masculine features were likely to be risky, competitive, ａｎｄ　more apt to fight, challenge bosses, cheat on spouses ａｎｄ　put less effort into parenting. Those with more feminine faces were seen as good parents ａｎｄ　husbands, hard workers ａｎｄ　emotionally supportive mates.But, despite all the negative characteristics, when asked who they would choose fｏｒa short-term relationship, women selected the more masculine looking men. Brad ａｎｄ　George, both chiseled jaws ａｎｄ　well-defined brows, then would be good fｏｒa brief romance, not fｏｒsomething longer.The study was published in the December issue of the US journal Personal Relationships.Kruger said that from an evolutionary perspective, this makes sense. The key is testosterone, the hormone responsible fｏｒthe development of masculine facial features ａｎｄ　other sexual characteristics. It has been found to affect the body\'s ability to fight disease: men with high levels of the hormone are typically strong ａｎｄ　healthy- traits women want to pass on to their children.However, increased testosterone has also been linked to ____ ａｎｄ　violence in relationships. So, these men might produce high quality offspring, but they don\'t always make great parents ｏｒfaithful mates, Kruger says.The scientific community have shown skepticism toward physiognomy, which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool fｏｒunderstanding mating strategies. And, of course, fｏｒexplaining why Tony Leung ａｎｄ　Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. ｏｒsomething to do with ours.【单选题】

A.cheat

B.cheats

C.cheated

D.cheating

正确答案:D

答案解析:这事同一个词表现出的不同形态变化。link后面的to是介词to而不是不定式to，因此须用cheating。

4、BaseballThere are people in Italy who can\'t stａｎｄ　soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who yawn ｏｒeven frown when somebody mentions baseball. Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens. They tell you it\'s a game better suited to the 19th century, slow, quiet ａｎｄ　gentlemanly. These are the same people you may be one of them who love football because there\'s the sport that glorifies "the hit".By contrast, baseball seems abstract, cool, silent ａｎｄ　still. On TV the game is fractured into a dozen perspectives, replays ａｎｄ　close ups. The geometry of the game, however, is essential to understanding it. You will contemplate the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the game affords so much space ａｎｄ　time fｏｒinvolvement. The TV won\'t do it fｏｒyou.Take, fｏｒexample, the third baseman. You sit behind the third base dugout ａｎｄ　you watch him watching home plate. His legs are apart, knees flexed. His arms hang loose. He does a lot of this. The skeptic still cannot think of any other sports so still, so passive. But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms ｏｒbring the glove to a point in front of him, takes a step right ｏｒleft, backward ｏｒforward, perhaps he glances across the field to check his first baseman\'s position. Suppose the pitch is a ball. "Nothing happened," you say. "I could have had my eyes closed".The skeptic ａｎｄ　the innocent must play the game. ａｎｄ　this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood if football is a symphony of movement ａｎｄ　theatre, baseball is chamber music, a spacious interlocking of notes, chores ａｎｄ　responses.The passage is mainly concerned with ____.【单选题】

A.the different tastes of people fｏｒsports

B.the different characteristics of sports

C.the attraction of football

D.the attraction of baseball

正确答案:D

答案解析:第一段简述了人们对垒球所持的偏见——无活力、从容和缓，不像橄榄球那样高潮迭起、令人激动。文章的第二、三、四、五段探讨了垒球的根本特征及欣赏角度，文章的最后一句话用一个比喻概括了垒球的魅力： “如果橄榄球是一曲交响乐的话，球中所表现出来的运动恰似一曲优美的室内乐。”可见，主要探讨的是垒球的特点及其欣赏。A不对，这段也确实提到了不同观众对不同运动形式的偏好，只是用以引出对垒球的特征及欣赏的讨论。

5、Life Expectancy in the Last Hundred YearsA hundred years ago, life expectancy in developed countries was about 47 in the early 21st century, men in the United States ａｎｄ　the United Kingdom can expect to live to about 74. Women to about 80, ａｎｄ　these ages are rising all the time. What has brought about these changes? When we look at the life span of people 100 years ago, we need to look at the greatest killers of the time. In the early 20th century, these were the acute ａｎｄ　often____ infectious diseases such as smallpox. Many children died very young from these diseases ａｎｄ　others, ａｎｄ　the weak ａｎｄ　elderly were always at risk.In the developed world these diseases are far less deadly today, ａｎｄ　in some cases have almost disappeared. A number of factors have led to this: improvements in sanitation ａｎｄ　hygiene, the discovery ａｎｄ　use of antibiotics, which make bacterial diseases much less dangerous, ａｎｄ　vaccinations against common diseases. In addition , people\'s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better ａｎｄ　warmer housing, ａｎｄ　better understanding of nutrition.Genetically, we should all be able to live to about 85 but while people do live longer today, there are still some big killers around that are preventing US from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease ａｎｄ　strokes, ａｎｄ　those spread by viruses, such as influenza ａｎｄ　AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect older people, but there are worrying trends in the developed world with problems such as obesity leading to more heart disease ａｎｄ　illnesses such as diabetes at younger ages.The killers today can be classed as "lifestyle diseases", which means that it may be possible to halt their progress.【单选题】

A.more

B.less

C.high

D.highly

正确答案:D

答案解析:本句举了天花的例子，下一句指出很多孩子死于这些病，所以此处应为一个表严重的词。high是形容词，不能修饰后面的形容词。acute不是比较级，所以and后面也不应用比较级。
