  A Great Quake Coming?

  Everyone who lives in San Francisco knows that earthquakes are common in the bay area and they can be devastating.In 1906,for example,a major quake destroyed about 28,000 buildings and killed hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's bound to happen someday.At least seven active fault(断层)lines run through the San Francisco area.Faults are places where pieces of Earth's crust(地壳)slide past each other.When these pieces slip,the ground shakes.

  To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens.

  One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists had assumed at the time.During small earthquakes,faults rupture(断裂)at about 2.7 kilometers per second.During bigger quakes,however,ruptures can happen at rates faster than 3.5 kilometers per second.

  At such high speeds.massive amounts of pressure build up,generating underground waves that can cause more damage than the quake itself.Lucky for San Francisco,these pressure pulses(脉冲)travel away from the city during the 1906 event.As bad as the damage was,it could have been far worse.

  Looking ahead,scientists are trying to predict when the next major quake will occur.Records show that earthquakes were common before 1906.Since then,the earthquake has been relatively quiet.Patterns in the data,however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent.

  New buildings in San Francisco are quite safe in case of future quakes.Still,more than 84 per-cent of the city's buildings are old and weak.Analyses suggest that another massive earthquake would cause extensive damage.

  People who live there tend to feel safe because San Francisco has remained pretty quiet for a while.According to the new reseaych,however,it's not a matter of"if the Big One will hit".It's just a matter of when.

  16.The San Francisco area is located above several active fault lines.

  A.Right

  B.Wrong

  C.Not mentioned

  17.The 1906 earthquake in San Francisco is the most severe one in American history.

  A.Right

  B.Wrong

  C.Not mentioned

  18.The highest speed of fault ruptures in the 1906 quake was more than 3.5 kilometers per second.

  A.Right

  B.Wrong

  C.Not mentioned

  19.Earthquakes rarely happened before 1906.

  A.Right

  B.Wrong

  C.Not mentioned

  20.San Francisco is fully prepared for another big earthquake.

  A.Right

  B.Wrong

  C.Not mentioned

  21.Scientist will be able to predict the exact time of an earthquake soon.

  A.Right

  B.Wrong

  C.Not mentioned

  22.A major earthquake striking San Francisco someday is inevitable.

  A.Right

  B.Wrong

  C.Not mentioned

第3部分:概括大意与完成句子(第23~30题,每题1分,共8分)

  下面的短文后有2项测试任务:(1)第23-26题要求从所给的6个选项中为第2~5段每段选择1个最佳标题;(2)第27~30题要求从所给的6个选项中为每个句子确定1个最佳选项。

  Natural Gas

  Natural gas is produced from reservoirs deep beneath the earth's surface.It is a fossil fuel,meaning that it is derived from organic material buried in the earth millions of years ago.The main component of natural gas is methane(甲烷).

  The popularity and use of clean natural gas has increased dramatically over the past 50 years as Dipeline infrastructure(基础设施)has been installed to deliver it conveniently and economically to millions of residential,commercial and industrial customers worldwide.Today,natural gas service is available in all 50 states,and is the leading energy choice for fueling American homes and indus-tries.More than 65 million American homes use natural gas.In fact,natural gas is the most eco-nomical source for home energy needs,costing one-third as much as electricity. In addition to heat-ing homes,much of the gas used in the United States is used as a raw material to manufacture a wide variety of products,from paint,to fibers for clothing,to plastics for healthcare,computing and fur-nishings. Natural gas is also used in a significant number of new electricity-generating power plants.

  Natural gas is one of the safest and cleanest fuels available. It emits less pollution than other fossil fuels.dioxide(二氧化碳)and water vapor-the same substances emitted when humans ex-hale.Compared with some other fossil fuels,natural gas emits the least amount of carbon dioxide in-to the air when combusted(燃烧)-making natural gas the cleanest burning fossil fuel of all.The industry also is subject to substantial federal regulation in the areas of production and distribution,which help ensure it is provided to consumers safely and cleanly.

  The United States consumes about one-third of the world's natural gas output,making it the lar-gest gas consuming region in the world.The U.S.Department of Energy's Energy Information Ad-ministration forecasts that natural gas demand will grow by more than 50 percent by 2025.

  There are huge reserves of natural gas beneath the earth's surface.The largest reserves of natu-ral gas can be found in Russia,West and North Africa and the Middle East.LNG(液化天然气)has been produced domestically and imported in the United States for more than four decades.To-day,the leading importers of LNG are Japan,Korea,France and Spain.

  23.Paragraph 2_______________

  24.Paragraph 3_______________

  25.Paragraph 4_______________

  26.Paragraph 5_______________

  A.Popularity and use of natural gas

  B.Natural gas reserves and supply

  C.Natural gas prices

  D.Clean fuel of choice

  E.Disadvantages of natural gas

  F.Natural gas consumption

  27.Natural gas is stored deep________.

  28.Natural gas is recognized as the most economical energy source ________.

  29.When manufacturing many products,people commonly use natural gas ________.

  30.It is estimated that by 2050 that natural gas demand in the United States will increase________.

  E.as a raw material

  F.for home energy needs

第4部分:阅读理解(第31-45题,每题3分,共45分)

  下面有3篇短文,每篇短文后有5道题。请根据短文内容,为每题确定1个最佳选项。

  第一篇

  Walking to Exercise the Brain

  Do you think sitting and studying all the time will improve your grades?Think again.Getting some exercise may help,too.

  New research with older people suggests that taking regular walks helps them pay attention better than if they didn't exercise.

  Previous research had shown that mice learn,remember,and pay attention better after a few weeks of working out on a running wheel.Mice that exercise have greater blood flow to the brain than those who don't.Their brain cells also make more connections. 外语~教育网编辑整理

  Neuroscientists from the University at Urbana-Champaign wanted to find out if the same thing is true for people.First,they measured the physical fitness of 41 adults,ages 58 to 77,after each per-son walked 1 mile.Then,participants looked at arrows on a computer sczeen and had to use com-puter keys to show which way one particular arrow was pointing.

  Adults who were physically fit were faster at the arrow task,and their answers were just as ac- curate as their less-fit peers,the researchers found.The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions.

  In a second study,15 elderly people who completed a 6-month aerobic-training course were fas-ter at attention tasks compared with 14 seniors who just did stretching and toning exercises for the same amount of time.

  So,even going for a walk every 2 or 3 days forjust 10 to 45 minutes can help.That should be good news for your grandparents.

  The effects of exercising on the brains of younger people haven't been studied yet.Still,it can't hurt to take occasional study breaks and go for a walk or run around with your friends.You might even do better in school.

  Whatever you do,though,don't try to read and walk at the same time.You could end up hurting yourseff!

  31.Walking regularly helps elderly people_______.

  A.lose weight

  B.become happier

  C.concentrate better

  33.The first study on 41 elderly people found______.

  A.the less-fit participants did arrow tasks faster

  B.the fitter participants did arrow tasks faster

  C.the less-fit participants gave more accurate answers

  D.the fitter participants gave more accurate answers

  34.It can be good for health when one takes a walk every 2 or 3 days for at least______.

  A.3 minutes

  B.45 minutes

  C.30 minutes

  D.10 minutes

  35.It is suggested in the last paragraph that people should______.

  A.run around once a week

  B.not read and walk at the same time

  C.go for a walk every day

  Night of the Living Ants

  When an ant dies,other ants move the dead insect out of the nest.This behavior is interesting to scientists,who wonder how ants know for sure and so soon that another ant is dead.

  Dong-Hwan Choe,a scientist at the University of California found that Argentine ants have a chemical on the outside of their bodies that signals to other ants."I'm dead.take me away."

  But there's a twist to Choe's discovery.These ants ave a little bit like zombies(僵尸).Choe says that the living ants,not just the dead ones,have this death chemicals.In other words.While an ant crawls around,perhaps in a picnic or home,it's telling other ants that it's dead.

  What keeps ants from hauling away the liring dead?Choe found that Argentine ants have two additional chemicals on their bodies,and these tell nearby ants something like,"Wait-I'm not dead yet,"So Choe's research turned up two sets of chemical signals in ants:one says,"I'm dead."the other set says,"I'm not dead yet."

  Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious,other ants leave it alone until it wakes up.That means ants know that unmoving ants can still be alive.

  Choe suspects that when an Argentine ant dies,the chemical that says"Wait-I'm not dead yet" quickly goes away.Once that chemical is gone,only the one that says"I'm dead"is left."It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard(墓地),not because its body releases new unique chemicals after death,"said Choe. When other ants detect the"dead"chemical without the"not dead yet"chemical,they haul away the body. This was choe's hypothesis(假设).

  To test his hypothesis,Choe and his team put different chemicals on Argentine ant pupae(蛹). When the scientists used the"I'm dead"chemical,other ants quickly hauled tbe treated pupae away. When the scientists used the"Wait-I'm not dead yet"chemicals,other ants left the treated pupae alone.Choe believes this behavior shows that the"not dead yet"chemicals override(优先于) the"dead"chemical when picked up by adult ants. And that when an ant dies,the"not dead yet"chemicals fade away.Other nearby ants then detect the remaining"dead"chemical and remove the body from the nest. 外语~教育网编辑整理

  36.What is meant by"death chemical"mentioned in paragraph 3?

  A.A chemical that contains poison.

  B.A chemical that causes death.

  C.A chemical that announces death.

  D.A chemical that prevents death.

  37.Which of the following statements is NOT true of ants?

  A.Ants know very soon that another ant is dead.

  B.When an ant is dead,others move its body out of the nest.

  C.If an ant is unconscious,it is moved out of the nest.

  D.Living ants have the"I'm dead"chemical on their bodies.

  38.According to Choe's hypothesis,___________.

  A.an ant still smells like a living when it dies

  B.the"I am dead"chemical leaves the ant's body when it dies

  C.the"I am not dead yet"chemical is left when an ant dies

  D.the"I am not dead yet"chemical leaves the ant's body when it dies

  39.According to paragraph 7,what is the result of the test on Choe's hyothesis?

  A.It shows that his hypothesis is wrong.

  B.It proves that his hypothesis is convincing.

  C.It suggests that his hypothesis needs revising.

  D.Not enough evidence has been found to support his hypothesis.

  40.The passage"Night of the Living Ants"tells us about________.

  A.how an ant is moved out of the nest at nigh

  B.what an ant does at night

  C.how an ant finds its way in darkness

  D.what happens when an ant dies

  The Iceman

  On a September day in 1991,two Germans were climbing the mountain between Austria and Italy.High up on a mountain pass,they found the body of a man lying on the ice. At that height (10,499 feet or 3,200 meters),the ice is usually permanent,but 1991 had been an especially warm year.The mountain ice had melted more than just usual and so the body had come to the surface.

  It was lying face downward.The skeleton(骨架)was in perfect condition,except for a wound in the head.There was still skin on the bones and the remains of some clothes.The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots.Nearby was a pair of gloves made of tree bark(树皮)and a holder for arrows.

  Who was the man? How and when had he died? Everybody had a different answer to these questions.Some people thought that it was from this century,perhaps the body of a soldier who died in World War I.since several soldiers had already been found in the area. A Swiss woman who believed it might be her father, who had died in those mountains twenty years before and whose body had never been found.The scientists who rushed to look at the body thought it was probably much older,maybe even a thousand years old.

  With modern dating techniques,the scientists soon learned that the iceman was about 5,300 years old.Born in about 3300 B.C.,he lived during the Bronze Age in Europe.At first scientists thought he was probably a hunter who had died from an accident in the high mountains. More recent evidence.however,tells a different story.A new kind of X-ray shows an arrowhead still stuck in his shoulder.It left only a tiny hole in his skin,but it caused internal damage and bleeding.He almost certainlv died from this wound,and not from the wound on the back of his head.This means that he was probably in some kind of battle.It may have been part of a large war,or he may have been fighting bandits.He may even have been a bandit himself.

  By studying his clothes and tools,scientists have already learned a great deal from the Iceman about the times he lived in.we may never know the full story of how he died,but he has given us important clues to the history of those distant times.

  41.The body of the iceman was found in the mountains mainly because__________.

  A.two Germans were climbing mountains

  B.he was just on a mountain pass

  C.the melted ice made him visible

  D.he was lying on the ice

  42.What can be inferred from paragraph 2?

  A.The iceman could have died from the wound in the head.

  B.The iceman was struck dead from behind.

  C.The iceman was killed while working.

  D.The iceman lived a poor life.

  43.All the following are assumptions once made about iceman EXCEPT____________.

  A.he was a soldier in Worid War I

  B.he came from Italy

  C.he was a Swiss woman'S long-lost father

  D.He was born about a thousand years ago

  44.The scientists made the deduction that the iceman_________.

  A.was hit in the shoulder by an arrowhead

  B.has a tiny hole in his skin causing his death

  C.was probably in some kind of a battle

  D.had got a wound on the back of his head

  45.The word"bandits"in paragraph 4 could be best replaced by_________.

  A.robbers

  B.shooters

  C.soldiers

  D.hunters

  Semco

  At 21,Ricardo Semler became boss of his father'S business in Brazil,Semco,which sold parts for ships.Semler Junior worked like a madman,from 7:30 am,until midnight every day.One afternoon,while touring a factory in New York,he collapsed.The doctor who 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 ways 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 set their own salaries,and he cut all the jobs he thought were unnecessary,like receptionists and secretaries.__________(46)."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.__________(47).As for uniforms,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 on the other side of the world fails,millions of gallons of oil are about to spill into the sea.Rubin springs into action._________(48).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.________(49).

  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 employees work hard for everyone else._________(50).In other words,Ricardo Semler treats his workers like aduhs and expects them to act like adults.And they do.

  A.This saved money and brought more equality to the company.

  B.He knows everything there is to know about our pumps and how to fix them.

  C.And the workers are free to decorate their workspace as they want.

  D.Most managers spend their time making it difficult for workers to work.

  E.If someone isn't doing his job well,the other workers will not allow the situation to continue.

  F.Also,Semco lets its workers use the company's machines for their own projects,and makes them take holidays for at least thirty days a year.

  "U.S.customs has been fingerprinting incoming foreign visitors for years."Tan says."unfortunately,for the Singaporean traveler,one potential_________(57)effect of his drug treatment is a smoothing of the tissue on the finger pads._________(58),no fingerprints."

  "It is uncertain when fingerprint___________(59)will begin to take place in patients who are taking capecitabine,"Tan points out.So he__________(60)any physicians who prescribe the drug to provide their patients with a doctor'S___________(61)pointing out that their medicine may cause fingerprints to disappear.

  Eventually,the Singapore traveler made it into the United States.I guess the name on his passport didn't raise any red flags. But he'S also now got the explanatory doctor's note-and won't leave home_______(62)it.

  By the way,maybe the Food and Drug Administration(美国食品药物管理局),____________(63) approved use of the drug 11 years ago,should consider updating its list of side effects _______(64)with this medicine.The current list does note that patients may experience vomiting(呕吐),stomach pain and some other side effects.But no where__________(65)it mention the potential for loss of fingerprints.

  第2部分:阅读判断

  16.B [解析]本题给出的信息是错误的。原文是:"At least seven active fault lines run through the San FranciSCO area."

  17.C [解析]文章没有谈到这方面信息。文章只提到1906年地震破坏性大,没说是最严重的。

  18.A [解析]本题给出的信息是正确的。原文是:"During bigger quakes,baowever,ruptures can laappen at rates faster than 3.5 kilometers per secona."由于1906年洛杉矶地震属于大地震,因此本句"1906年洛杉矾地震断层最高速度超过每秒3.5公里"是正确的。

  19.B [解析]本题给出的信息是错误的。原文是:"Recorcls show that earthquakes were common before 1906."

  20.B [解析]本题给出的信息是错误的。原文是:"still,more than 84 percent of the city's buildings are old and weak."既然大多数房屋不能抵挡地震,那么洛杉矶并没有为地震的来临做好准备。

  21.C[解析]文章没有谈到这方面信息。

  22.A[解析]本题给出的信息是正确的。原文是:"According to the new research,however,it's not a matter of'if the Big 0ne will hit'.It's just a matter of wllen."既然问题是"地震什么时候会发生",那么这一地震是无法避免的了。

  参考译文

  大地震就要来了?

  住在旧金山的人都知道海湾地区地震高发,而且具有毁坏性。例如1906年的地震毁坏了28000座建筑,让成百上千的人丧命。现在这里的居民想知道下次"大地震"到来的时间,它在某天必定会发生。现在至少有七条活跃的断层线穿过旧金山。断层是地壳破裂面互相移动形成的。当这些破裂面滑动时地震就发生了。

  为了迎接那一天,科学家用新技术重新分析1906年的地震,并估计下次地震有可能造成的破坏。

  关于1906年地震的一个新发现是圣安德烈亚斯断层分裂的速度比当时科学家认为的要快。小地震发生时断层以每秒2.7公里的速度断裂。然而在大地震时断层断裂速度每秒可超过3.5公里。

  在如此高速下聚集了大量压力,并产生比地震本身破坏性更强的地下波。洛杉矶算幸运的,1906年这些压力脉冲游离了该城。尽管破坏很严重,但总算避免了更糟糕的后果。

  展望未来,科学家在估计下次大地震什么时候发生。记录显示1906年前地震频发。自此,地震相对减少。然而数据模式显示2032年前一场大地震袭击湾区的可能性至少有62%。

  旧金山的新建筑即使在地震中也是完全安全的,但城里超过84%的旧建筑仍是不坚固的。分析家暗示再来一次大地震会造成大面积破坏。

  居民觉得住在旧金山是安全的,因为很长一段时间来都很平静。然而根据新的研究,问题已不再是"是否将会发生大地震",而是"什么时候它会来"。

  参考译文

  天然气

  天然气深深储藏在地球表面下方,它属于矿物燃料,是埋藏在地球上百万年的有机物产生的。天然气的主要构成是甲烷。

  过去50多年,随着管道基础建设能将气体便利、经济的输送到世界各地的居住区、商业和工业用户,天然气受欢迎程度和使用迅速增长。如今全美50州都有天然气服务,并且是美国家庭和工业燃料首选。超过6500万美国家庭使用天然气。事实上,天然气是最经济的家庭能源的来源,费用是电的1/3。除了家庭取暖,美国许多天然气被用作原材料,生产从油漆到服装纤维、保健用塑料制品、计算设备和家具等多种产品。天然气也被用在许多新的发电厂。

  天然气是现有能源中最安全和最干净的。它释放的污染小于其他矿物燃料。天然气燃烧时主要产生二氧化碳和水蒸气--与人呼气产生的物质相同。与其他矿物燃料相比,天然气燃烧时释放到空气中的二氧化碳最少,因此它是最洁净的燃烧矿物燃料。燃料的生产和分配必须按照联邦政府的规定,这样能确保向消费者提供安全干净的服务。

  美国消费世界天然气出产量的三分之一,是世界上最大的天然气消费地区。美国能源部的能源信息行政部门预计天然气需求量到2025年会增长超过50%。

  地表下有大量的天然气储存。最大的天然气储存在俄罗斯、西非、北非和中东。过去的四十多年美国同时本土生产和进口液化天然气。现在进口液化气的国家主要有日本韩国、法国和西班牙。

  参考译文

  步行健脑

  你认为整日坐着学习就可以提高成绩么?想想吧。做做运动或许也有效呢。

  对老年人的新研究显示经常运动能让老年人更集中精力。

  以前的研究证明老鼠在轮子上奔跑数周后它们的学习、记忆和集中程度都有所提高。运动的老鼠大脑中的血液流量大于不运动的,而它们脑细胞的联系也更频繁。

  来自Urbana-Champaign大学的神经学家想要知道是否人类也会有同样的情况。首先,他们测量了41位58岁到77岁的成年人行走1英里后的健康状况。然后让这4l位参加者观看电脑屏幕上的箭头,用电脑操纵键指出箭头指向哪里。

  研究员发现身体健康的成年人完成箭头测试的速度更快,他们的答案和身体状况不佳的参加者一样准确。有更多的血液流向健康参加者大脑中控制注意力和做决定的部分。

  第二项试验中,已完成了一个六个月有氧训练课程的老年人在注意力测试中比另外14位只是做过同样时间的伸展和肌肉锻炼的老年人要更快。

  因此每两到三天仅仅出去散步10到45分钟都会对健康有益。这对你的祖父母来说是个好消息。

  运动对年轻人大脑的作用尚未有研究。不过,偶尔放下学习,和朋友们散散步、跑一跑还是有好处的。或许对学习大有裨益。

  不管你怎么做都不要一边走路一边读书,你有可能伤到自己的哦。

  参考译文

  蚂蚁的死亡

  一只蚂蚁死后,别的蚂蚁会把它挪出蚁穴。科学家认为这一现象很有趣,他们想知道蚂蚁们如何迅速准确地得知有只同伴死了。

  加州大学科学家周东环发现阿根廷蚂蚁的身体能向外释放一种化学物质告诉同伴:"我死了,把我挪走吧。"

  让周东环在研究中疑惑不解的是蚂蚁都像僵尸一般,不仅是死蚂蚁,活的蚂蚁也有这种死亡化学物质。换句话说,当一只蚂蚁在餐厅或家中爬行时,它就在告诉同伴他死了。

  是什么令蚂蚁们并没有拖走活着的同伴?周发现阿根廷蚂蚁身体上有两种化学物质,这些物质能向周围的蚂蚁传达诸如"等等,我还没死呢"这样的信息。因此,周的研究发现了两种化学物质信号。一种说明"我死了",另一种说"我还没死呢"。

  其他科学家也试图发现蚂蚁如何知道一个同伴已经死去。如果一个蚂蚁昏迷了,其他蚂蚁能在它醒过来前不碰它。这意味着蚂蚁们知道没有动的同伴有可能仍然活着。

  周指出,当一只阿根廷蚂蚁死后,发出"等等,我还没死呢"这一信号的化学物质立刻消失。一旦这种物质消失,就只有发出"我死了"的化学物质。周说,"这是因为死去的蚂蚁散发的味道不同于活着的蚂蚁,因而应该被带到坟墓去了。并不是因为蚂蚁在死后产生新化学物质。"当其他蚂蚁监测到"我没死"化学物质消失了,而只有"我死了"物质,它们就将尸体拖走。这是周的假设。

  为了证明这一假设,周和他的团队将不同的化学物质涂在阿根廷蚂蚁的蛹上。当科学家用"我已死"化学物质时,蚂蚁们立刻将处理过的蛹拉走。当科学家使用"等等,我还没死"这一化学物质时,其他蚂蚁并不碰这个蛹。周认为这一行为说明蚂蚁选择时,"还没死"物质要优先于"死亡"物质。而且当一只蚂蚁死后,"还没死"化学物质逐渐消失。其他周围的蚂蚁才感觉到"死亡"物质,并将尸体拖离蚁穴。

  第三篇

  41.C[解析]本题是细节考查题。冰人尸体被发现的原因在文章的第一段提到。选项A"两个德国人正在爬山";选项B"他刚好在一个山口上";选项C"融化的冰将他暴露出来";选项D"他躺在冰上"。因此只能选C。

  42.A[解析]本题是阅读理解能力考查题。能从第二段推断出的是以下哪项?选项A "冰人有可能死于头部伤口";选项B"冰人背后受袭击而致死";选项c"冰人工作时被杀害";选项D"冰人生活贫困"。原文是"它面朝下,除了头部有伤外,骨架状况很好",仅就此推断,冰人可能死于头部伤,因此答案是A。

  43.B [解析]本题是细节考查题。原题是下列哪项不属于人们对冰人作出的种种猜测。原文在第三段。选项A"他是一战时期的士兵";选项C"他是一位瑞士妇女失踪多年的父亲";选项D"他大约一千年前出生"均在该段中有所提及。选项B"他来自意大利"在文章中没有出现。因此答案是B。

  44.C [解析]本题是细节考查题。原题是科学家对冰人的推论是什么。原文在第四段。选项A"他的肩膀被箭头刺伤"是事实而非推论;选项B"皮肤上的小孔导致他的死亡"不符合事实;选项C"有可能参与过战斗"是推论;选项D"头后部有伤口"是事实而非推论因此只能选C。

  45.A [解析]本题是阅读理解能力考察题。第四段"bandits"是什么意思?选项A"强盗";选项B"射击手";选项C"士兵";选项D"猎人"。只有选项A与其他三项意义相距甚远。因此只能选A。

  参考译文

  冰人

  1991年九月的一天,两位德国人正在攀登奥地利和意大利之间的山脉。爬到一个山口它们发现了一具躺在冰上的尸体。在这样的高度(10499英尺或3200米),冰通常是常年不化的。但是1991年是特别暖的一年,山上的冰比从前消融的迅速,所以尸体才显露出来。

  他面朝下,除了头部有伤外,骨架状况很好。骨头上依然有皮肤和残余的衣物。尸体双手仍然握着斧头的木柄,双脚穿着简单的由皮革和布料做的靴子,他附近有树皮做的一双手套和一个箭筒。

  他是谁?他在什么时候怎样死去的?人人的解释都不同。有人认为他就是本世纪的人,有可能是一战时期阵亡的士兵,因为在这附近已经有士兵被发现了。一位瑞士妇女相信他是自己二十年前在这些山脉间去世的父亲,他的遗体一直没有被找到。赶去查看的科学家认为这一尸体可能更久远,它甚至有一千岁了。

  科学家们运用最新的年代确定技术很快获悉这一冰人已有大约5300岁了。他大约出生在公元前3300年,生活在欧洲的青铜器时代。起初科学家们认为他有可能在高山间打猎时出事故而身亡。然而最近的一些证据显示不同。新型的X光表明他的肩膀上仍有一个箭头,皮肤上只有一个小孔,但却导致内部损伤和失血。几乎可以肯定他死于这个伤,而不是脑后的伤口。这说明他有可能参与过战争。这场战争有可能是大型战争的一部分或者其间他和强盗博斗过,甚至他本人就可能是强盗。

  通过研究他的衣服和工具,科学家们就已经知道有关冰人生活的时代的很多内容。我们有可能永远无法知道他死亡的真相,但是他给我们提供了了解那个远古时代的重要线索。

  第5部分:补全短文

  46.A [解析]本题考查的是对上下文之间意义关系的理解和对文章细节的把握。上一句说到"他允许他们自己制定薪水,但会削减他认为不必要的,比如像接待员和秘书这样的工作",而下一句应该解释这种做法的原因。选项A说明"这样可以减少开支,并给公司带来更多平等",与上下文联系最紧密,因此选A。

  47.C [解析]本题考查的是对段落主旨的理解和对文章细节的把握。本段主要讲semler如何改造公司的外表,而选项中只有C提到这方面的内容,"员工可以随意装饰自己的工作空间"放在这里是和前后两句话的并列。因此选C。

  48.B [解析]本题考查的是对上下文之间意义关系的理解和对文章细节的把握。上一句说到"但如果Semco在地球另一端的油泵坏了,上百万加仑的油即将注入大海时,Robin就会立刻跳起来行动",下一句需要说到Robin怎样行动,因此选项B"他了解关于我们公司油泵的任何事情,并能修理"最符合题目要求。

  49.F [解析]本题考查的是对段落主旨的理解和对文章细节的把握。这一段讲述了Semco给予员工的自由,而选项中只有F"Semco也允许员工用公司的机器做自己的项目,并且一年至少能休假30天"与此内容相关,因此选F。

  50.E [解析]本题考查的是对上下文之间意义关系的理解。上一句说到同伴的压力让员工努力为他人工作,而下一句应具体解释这种压力如何发挥作用。选项E"如果有人表现不好。其他人会制止这一局面"延续了这一句的内容。因此选E。

  参考译文

  Semeo

  Ricardo Semler 21岁就做了父亲在巴西的公司Semco的老板,该公司出售轮船部件。小semler是个工作狂,每天从早上七点半工作至深夜。一天下午,他在纽约参观工厂时晕倒了,治疗医生说:"你身体没有什么毛病,但你若一直这样工作,你会长期待在医院的。"semler听从了医生的话。他改变了自己的工作方式,事实上也改变了员工的工作方式。

  他让员工担负更多责任,让他们为事情偏离轨道而担忧。他允许他们自己制定薪水,并且削减他认为不必要的,比如像接待员和秘书这样的工作。这样可以减少开支,并给公司带来更多平等。Semco的每个人,甚至高管都要自己接待客人、复印、发传真、打字和打电话。

  他完全改造了semco:办公室没有墙,而是植物,因此老板不能与其他人隔开。员工可以随意装饰自己的工作空间。制服方面,则有人穿西装,有人穿体恤。

  Semler说:"我们有个坐在那里看几个小时报纸的销售经理,叫Rubin Agater。他甚至不用去装着很忙碌的样子。但如果Semco在地球另一端的油泵坏了,上百万加仑的油即将注入大海时,Robin就会立刻跳起来行动。他了解关于我们公司油泵的任何事情,并能修理。那就是他挣工资的时候。别人并不关心其他时间他是否看上去忙忙碌碌。"

  Semco有弹性工作时间:员工自己决定什么时候来上班,并且一年要两次评估老板。Semco也允许员工用公司的机器做自己的项目,并且一年至少能休假30天。

  听上去很好?但这一切都起作用了么?答案在数字中:在过去的六年里,Semco的收入从三千五百万美元上升到两亿一千二百万美元。公司员工数量从八百增长到三千。为什么会发生这一切?

  Semler认为这是因为"同伴的压力"。同伴的压力让员工努力为他人工作。如果有人表现不好,其他人会制止这一局面。换句话说,Ricardo semler给员工以成人的待遇,并希望他们有成人的行为。他们都做到了。

  参考译文

  指纹消失事件

  一种非常有效的抗癌药物能够清除箩状指纹和其他使指纹与众不同的标志。失去指纹可是会有很大麻烦。一封被肿瘤学年报在网上公布的信件说明了失去指纹会带来多大麻烦。

  Eng-Huat ran,一个新加坡籍的医学博士描述了用卡培他滨治疗一位患鼻咽癌的62岁老人的经历。经过这个药物三年的治疗后,这位病人去年十二月份决定去美国拜访亲戚。在他进入这个国家后,他被美国海关人员拦截了4小时之久,因为这些官员无法从他身上获取指纹。在他的食指上没有独特的旋涡状的指纹标记。

  "美国海关数年以来一直都会采集来访外国人的指纹,"Tan说:"不幸的是,对于这位新加坡旅行者来说,药物治疗的一个潜在的副作用就是会使指尖上的肉垫组织变光滑,因此会没有指纹。"

  "对于服用卡培他滨的病人来说,指纹何时会消失是不确定的,"Tan指出。所以他警告每位医师在给病人开药时要给病人开具他们的药物可能会使指纹消失的证明单。

  最终,那位新加坡旅客终于进入了美国。我猜想他护照上的名字没有带有任何危险信号。但是他同样要带有医师开的证明单--并且要随身携带。

  顺便提一下,美国食品药物管理局已经准许这一药物的使用有11年之久了,应该考虑更新与该药物有关的副作用清单。现有的副作用清单中确实列出病人会经历呕吐、胃痛和其他副作用,但是却没有提及失去指纹的潜在危险。
