1、Egypt Felled by Famine Even ancient Egypt\'s mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC. Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame ａｎｄ　the same ｏｒworse could happen today. The ancient Egyptians depended on the Nile\'s annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out of Ethiopia would have diminished these floods. Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile ａｎｄ　into Egypt, along with sediment from the White Nile. The Blue Nile mud has a different isotope signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river. Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypt\'s Old Kingdom. The weakened waters would have been catastrophic fｏｒthe Egyptians. " Changes that affect food supply don\'t have to be very large to have a ripple effect in societies," says Bill Ryan of the Lamont Doberty Earth Observatory in New York. "Similar events today could be even more devastating," says team member Daniel Stanley, a geoarchaeologist from the Smithsonian Institution in Washington, D C. " Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. " Which of the following factors was ultimately responsible fｏｒthe fall of the civilization of ancient Egypt? 【单选题】

A.Change of climate.

B.Famine.

C.Flood.

D.Population growth.

正确答案:A

答案解析:A：气候的变化。第一段中有这样一个子句… a shift in climate… was ultimately to blame…最终须归咎于气候的变化。在第一题的题解中，我们提到了“饥荒”与“古埃及文明毁灭”的关系。但“饥荒”是表层的因素，“气候的变化”才是古埃及文明毁灭的深层的因素。因此A是正确的答案。B：饥荒。C：水灾。D：人口增长。

2、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 ____ 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 days 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.all

B.large

C.will

D.it

正确答案:A

答案解析:本题难度不大，考查固定搭配not at all，指“根本不”，答案是A。

4、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。

5、GypsiesWhen school was out, I hurried to find my sister ａｎｄ　get out of the schoolyard before seeing anybody in my class. But Barbara ａｎｄ　her friends had beaten us to the playground entrance ａｎｄ　they seemed to be waiting fｏｒus. Barbara said, "So now you\'re in the A class. " She sounded impressed. "What\'s the A class?" I asked. Everybody made superiｏｒyet faintly envious giggling sounds. "Well, why did you think the teacher moved you to the front of the room, dopey? Didn\'t you know you were in the C class before, way in the back of the room?" Of course I hadn\'t known. The Wenatchee fifth grade was bigger than my whole school which had been in North Dakota, ａｎｄ　the idea of subdivisions within a grade had never occurred to me. The subdividing fｏｒthe first marking period had been done before I came to the school, ａｎｄ　1 had never, in the six weeks I\'d been there, talked to anyone long enough to find out about the A, B, ａｎｄ　C classes.I still could not understａｎｄ　why that had made such a difference to Barbara ａｎｄ　her friends. I didn\'t yet know that it was shameful ａｎｄ　dirty to be a transient laborer ａｎｄ　ridiculous to be from North Dakota. I thought living in a tent was more fun than living in a house.I didn\'t know that we were gypsies, really (how that thought would have excited me then!), ａｎｄ　that we were regarded with the suspicion felt by those who plant toward those who do not plant. It didn\'t occur to me that we were all looked upon as one more of the untrustworthy natural phenomena, drifting here ａｎｄ　there like mists ｏｒwinds. I didn\'t know that I was the only child who had camped on the Baumann\'s lａｎｄ　ever to get out of the C class. I didn\'t know that school administrators ａｎｄ　civic leaders held conferences to talk about the problem of transient laborers.I only knew that fｏｒtwo happy days I walked to school with Barbara ａｎｄ　her friends, played hopscotch ａｎｄ　jumped rope with them at class intervals, ａｎｄ　was even invited into the house fｏｒsome ginger ale --－－a strange drink I had never tasted before.Immediately after the narratｏｒwas moved to the A class, what was the attitude of Barbara ａｎｄ　Barbara\'s friends towards her?【单选题】

A.Dislike

B.Acceptance

C.Apology

D.Jealousy

正确答案:C

答案解析:答对题的关键是准确地理解这个题。这个题提问的焦点是：叙述者刚刚升入A班后( Immediately after…A class)，Barbara及其朋友对她是什么态度。仔细审视一下本题，我们就会得出这样一个结论： 在叙述者介入A班后，Barbara等起初是一种态度，而后，她们改变了这种态度。从原文第四段第三句我们了解到：叙述者与Barbara等在那个学校上学至少有六个星期了，只是不知道A、B、C班的分班基础。同时，在文章最后一段，我们了解到：叙述者与Barbara等至少共度了两天的快乐时光，如课间(at class intervals)一起玩，到她们家做客等。很明显，这两天说的是叙述者刚刚升入A班。
