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、Smart Window Windows not only let light in to cut down an electricity use fｏｒlighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark ａｎｄ　anywhere in between with a flip of a switch. "It took us a long time to figure out what a window really is," says Claes Granqvist. He\'s a professｏｒof solid-state physics at Uppsala University in Sweden. "It\'s contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows ａｎｄ　natural light are important fｏｒimproving the way people feel when they\'re stuck indoors. Yet, windows are the weak link in a building when it comes to energy ａｎｄ　temperature control. In the winter, cold air leaks in. When it\'s hot ａｎｄ　sunny, sunlight streams in. All of this sunlight carries lots of heat ａｎｄ　energy. ａｎｄ　all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world. Windows have been a majｏｒfocus of energy research fｏｒa long time. Over the years, scientists have come up with a variety of strategies fｏｒcoating, glazing, ａｎｄ　layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color. Electrochromic windows use electricity to change color. Fｏｒexample, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied ａｎｄ　dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it\'s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear ｏｒdark. One important feature that makes a smart window so smart is that it has a sort of "memory. " All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different. Which of the following statements does not indicate the importance of windows as described in the first two paragraphs? 【单选题】

A. Windows can change from clear to dark to save energy.

B.Windows help to save energy by letting light in.

C.Windows help to save energy by providing heat.

D.Windows enable people to have contact with the outside world.

正确答案:D

答案解析:借助文章中的用词特点或文章开头的语句进一步了解这篇文章的主题：文章讲介绍一种智能窗户。

3、Nurse! I Want My MummyWhen a child is ill in hospital, a parent\'s first reaction is to be with them.Most hospitals now allow parents to sleep overnight with their child, providing a bed ｏｒsofa on the ward.But until the 1970s this practice was not only frowned upon (不赞同) — it was actively discouraged. Staff worried that the children would be upｓｅｔwhen their parents left, ａｎｄ　so there was a blanket (通用的) ban.A concerned nurse, Pamela Hawthorn, disagreed ａｎｄ　her study "Nurse, I want my mummy!" published in 1974, changed the face "paediatric (儿科的) nursing.Martin Johnson, a professｏｒof nursing at the University of Salford, said that the work of nurses like Pamela had changed the face of patient care."Pamela\'s study was done against the background of a lively debate in paediatrics ａｎｄ　psychology as to the degree women should spend with children in the outside world ａｎｄ　the degree to which they should be allowed to visit children in hospital.""The idea was that if mum came to visita small child in hospital the child would be upｓｅｔａｎｄ　inconsolable (无法安慰的) fｏｒhours. ""Yet the nurse noticed that if mum did not come at all the child stayed in a relatively stable state but they might be depressed. ""Of course we know now that they had almost given up hope that mum was ever coming back.""To avoid a little bit of pain they said that no one should visit.""But children were alone ａｎｄ　depressed, so Hawthorn said parents should be allowed to visit."Dr. Peter Carter, chief executive ａｎｄ　general secretary of the Royal College of Nursing, said her work had been seminal (开创性的)."Her research put an end to the ____ when parents handed their children over to strangers at the doｏｒof the hospital ward.""As a result of her work, parents are now recognized as partners in care ａｎｄ　are afforded the opportunity to stay with their children while they are in hospital, which has dramatically improved both parents\' ａｎｄ　children\'s experience of care." 【单选题】

A.months

B.days

C.weeks

D.hours

正确答案:B

答案解析:本题难度不大，考查词义辨析，可以先看选项得到信息提示。文章此处是说“她的研究结束了家长在医院病房门口把孩子交给陌生人照顾的时代”，days指“时代，日子”，答案是B。

4、I enjoyed the play-it had a clever plot ａｎｄ　very funny dialogues.【单选题】

A.long

B.boring

C.original

D.humorous

正确答案:D

答案解析:我喜欢这部剧一一它情节巧，对白幽默。本题难度不大，是送分题。funny指“滑稽的，有趣的”，和humorous“富有幽默感的”是近义词，A项“长的”，B项“单调的，乏味的”，C项“起初的，原来的”和答案意义差异很大，干扰性不强。

5、Acceptance of Chronic IllnessFｏｒchronically ill patients, giving up the hope that they will get better may actually lead to more happiness, U. S. researchers suggest."Hope is an important part of happiness, but there\'s a dark side of hope. Sometimes, if hope makes people put off getting on with their life, it can get in the way of happiness," Dr. Peter A. Ubel from the University of Michigan Health System said in a university news release.He ａｎｄ　his colleagues studied patients who\'d just had a colostomy (结肠造口术), which means their colons (结肠) were removed ａｎｄ　they had to have bowel (肠) movements in a pouch (小袋) outside the body. At the time of the surgery, some patients were told the procedure was reversible ａｎｄ　they\'d have a second operation in a few months to reconnect their bowels. Other patients were told the colostomy was permanent.The patients were followed fｏｒsix months, ａｎｄ　the researchers found that those without hope of regaining normal bowel function were happier than those with reversible colostomies."We think they were happier because they got on with their life. They realized the cards they were dealt, ａｎｄ　recognized that they had no choice but to play with those cards," Ubel said. "The otherｇｒｏｕｐwas waiting fｏｒtheir colostomy to be reversed. They contrasted their current life with the life they hoped to lead, ａｎｄ　didn\'t make the best of their current situation. "The study, published in the November edition of Health Psychology, also may explain why people whose spouse dies often recover better emotionally over time than those who get divorced, the researchers said.That\'s because people whose husbａｎｄ　ｏｒwife dies have closure (结束), while those who get divorced may still have hope fｏｒsome chance of making up, they explained.Oneｇｒｏｕｐof the patients was happier because ______.【单选题】

A.they made the best of their current situation

B.they were good at playing cards

C.they regained normal bowel function

D.they were promised another operation

正确答案:A

答案解析:本题有一定难度，需要吃透原文句意。答案依据比较明显，在文章第五段最后一句，谈到，不开心的第一组病人总是把现在的生活和他们想要的生活进行比较，没有很好地适应现在的生活。换句话说，另一组病人之所以开心是因为适应了现在生活，回来看选项，A项和原文句意相符，是答案。
