This is fine until you need to call someone for help, only 27 (find) your phone is not around.And some people 28 also have lost their sense of direction because navigation apps can guide people anywhere they want.These apps can even find 29 (short) routes for you and avoid traffic jams.People get so dependent on them that when they can’t use their smart phones,they get lost and anxious.But the worst lost skills may be social ones,30 (mean) that some people are becoming socially inept(无能的).People often bury themselves in their smart phones.As we’re too distracted by what’s happening in the virtual(虚拟的)world,some of us have lost conversational skills and sometimes can’t even tell whether a person is happy or not.In August, researchers at the University of California,Los Angeles,studied 5l students aged 11 and l2 who had over five hours’ screen time every day.Their task was to tell the emotions of 48 pictures of faces that were happy,sad,angry, or scared.The children made an average of l4.02 mistakes at the beginning.31 after a five-day camp without electronic devices,they made only 9.41 mistakes on average.Luckily,people still have a chance to get these abilities back.You should try to keep your parents’ numbers in mind for emergencies.You should also pay more attention to street signs and stores,32 will help you to draw a mind map and prevent you from getting lost.And the easiest solution to social skill loss is to take a break from electronic devices.(B)Late last year, US researchers at the Buck Institute of Age Research claimed that the future life span of human beings would be 500 years.But that idea 33 (challenge) at a recent medical conference in the UK.Speaking at the conference,British neurobiologist(神经生物学家),Sir Colin Blakemore,claimed there is a limit on how long humans call live,and how much the body can age.34 500 years,120 years “might be a real absolute limit to human lifespan'’,he said.His estimate,35 (base) on current statistics and a look at medical effects,seems a little convincing.The number of people living past l00 in the world has soared by 71 percent in the past decade and Blakemore agreed that this figure would continue to rise.But people living for longerthan l20 years is “so rarely exceeded” 36 ,even with medical and technological advances, it is unlikely that we can achieve 37 we expect,he said.But 38 number is the ceiling for our life spans,120 or 500 years,it would take years for scientists to make that true for most people.We don’t have to complet ely rely on scientific breakthroughs to live a longer life,however.On Oct 21,the Gerontological Society of China published a report on centenarians(百岁老人)in China. There are 58,789 people above the age of l00 now in our country, with the oldest being 128 ye ars old. And by looking at these people’s lifestyles,39 society worked out a recipe for a long life:outdoor activities,more communication with others,and a healthy diet containing lots of fruit, vegetables,and low-fat food.So how long do you think you could live? If you play your part,your answer could be a satisfying 40.Section BDirections:Complete the following passage by using the words in the box.Each word can only be used once.Note that there is one word more than you need.The city has always been an engine of intellectual life,from the l8th.century cafes of London, where citizens gathered to discuss chemistry and politics,to the Left Bank bars of modem Paris, where Picasso talked about modern art.Without these 41 ,we might not have had the great art of Shakespeare.And yet,city life isn’t easy.Now scientists have begun to examine how the city affects the brain, and the results are 42 .Just being in an urban environment,they have found,impairs(损害)our basic mental processes.After spending a few minutes on a crowded city street,the brain is less able to hold things in memory, and suffers from reduced self-contr01.While it’s long been recognized that city life is exhausting,this new research suggests that cities actually 43 our thinking,sometimes dramatically so.One of the main forces at work is a complete lack of nature,which is surprisingly 44 for the brain.Studies have demonstrated,for instance,that hospital patients recover more quickly when they can see trees from their windows, and that women livingin public housing are 45 able to focus when their apartments overlook a lawn.Even these glimpses of nature improve brain performance,it seems,because they 46 a mental break from the urban life.This research arrives Just as humans cross all important milestone.For the first time in history, the majority of people live in cities.Instead of 47 wide-open spaces,we’re crowded into concrete jungles,surrounded by traffic and millions of Strangers.In recent years,it’s become clear that such unnatural surroundings have important implications for our mental and physical health, and call powerfully alter how we think.This research is also leading some scientists to dabble(涉足)in urban design,as they look for ways to make the city less 48 to the brain.The good news is that even slight alterations,such as planting more trees in the inner city or creating urban parks with a greater variety of plants,can 49 reduce the negative side effects of city life.The mind needs nature, and even a little bit can be a big 50.III.Reading ComprehensionSection ADirections:For each blank in the following passage there are four words or phrases marked A,B,C and D.Fill in each blank with the word or phrase that best fits the context.Why do people go to university? There is a popular notion that a college education is something to be endured in order to become 51 to obtain certain kinds of jobs or to go to graduate school.This is not what we are trying to do at Harvard,nor would we wish to have many students here who took such a(n) 52 view of a college career.There are several goals we aim to reach in our undergraduate program.The most obvious one is to give knowledge-fairly 53 knowledge in one field and a more general knowledge of a variety of other subject areas which you may choose according to your interest.But if acquiring knowledge is a self-evident part of a college education,it is 54 the most important.Remarkably few of the facts you learn here will remain in your 55 for many years,and some of those that do will even be proved 56 by new knowledge.57 ,we can instill(灌输)certain attitudes of mind—a willingness to accept uncertainty,and the lack of definite truths,independence of mind,and a respect for facts and tor the uncomfortable conclusions which facts sometimes lead to.In addition to these 58 qualities,a college education should try to lay a foundation tor the creative use of 59 time.Some of this capacity can be stimulated in the classroom-in courses in the humanities and the arts.Yet, at least as much 60 will occur outside the lecture hall-on athletic fields,in music rooms,student theaters,concert halls,and so forth.These are some of the 61 of a liberal college education as I see them.I cannot resist concluding with a few private thoughts about our new careers at Harvard.To begin with,I hope that we will think 62 about what we want to accomplish here.It would be 63 for you to set your sights on some limited goal,such as getting good grades or merely getting into one or another graduate school.Second, I hope that you will give some thought to what you can do for others during your stay here.There are many problems waiting for your help,and many people who could 64 your efforts.My final bit of advice.Whatever else we do,let us remember not to take ourselves too seriously.However great our problems may seem,however urgent our complaints,they are overshadowed by the 65 of countless other people on our planet.51.A. fascinated B. qualified C. determined D. required52.A. optimistic B. strong C. narrow D. sensitive53.A. concentrated B. expanded C. informed D. illustrated54.A. by far B. far from C. free from D. without doubt55.A. memory B. position C. evaluation D. foundation56.A. useful B. essential C. false D. common57.A. Besides B. However C. Therefore D. Somehow58.A. physical B. inborn C. emotional D. intellectual59.A. business B. study C. experiment D. leisure60.A. appreciation B. stimulation C. participation D. exposure61.A. threats B. aims C. problems D. souvenirs62.A. broadly B. honestly C. luckily D. continually63.A. fantastic B. magic C. tragic D. basic64.A. suffer from B. profit from C. reflect on D. complain about 65.A. inspiration B. difference C. ambitions D. difficultiesSection BDirections:Read the following three passages.Each passage is followed by several questions or unfinished statemems.For each of them there are four choices m址ed A,B,C and D.Choose the one that fits best according to the information given in the passage you have just read.(A)Pediatrician Avraham Kadar faced the challenge of explaining complex medical concepts to kids he was treating. In 1999,he found a solution,mad teachers have been harvesting the benefits ever since.Kadar created BrainPOP,an educational program consisting of brief animated videos in which a man named Tim and his robot friend Moby discuss various subjects.The videos fall into seven categories:engineering and technology,science,social studies,English,math,health,and arts and music.They cover over 500 topics,from historical figures to recent inventions,cultivating interest in the subjects through humor and illustrations.BrainPOP’s materials also include quizzes,activities,answers to questions and extra information about each topic.Almost 20 percent of American schools have embraced BrainPOP, and its popularity is growing worldwide.Its website,apps and products have won multiple awards from magazines,websites and other organizations.Kadar could not have developed BrainPOP without the help and support of his wife,Naomi.After graduating from college in the U.S.,Naomi taught English in Israel,where she married Avraham.After they returned to the U.S.,she focused her attention on teaching Yiddish,a language that she learned from her parents.Because of her background in educmion,she was helpful in developing BrainPOP.Afterward,she helped create BraillPOP ESL,a product designed to teach English as a second language to kids.After a difficult battle with cancer,Naomi passed away in 2010.In her memory,the Naomi Prawar Kadar Foundation was founded.Its primary mission is to promote Yiddish language learning.but it also trains teachers in other fields and supports medical research.66.What does Avraharn Kadar do as a doctor?A.He cares for the elderly.B.He operates a famous hospital.C.He treats childhood diseases.D.He develops heart medicine.67.According to this article,who are featured in BrainPOP’s videos?

Should we not rather encourage many ways for self-respecting people to work? Should we not create conditions in which many of us can work for ourselves,rather than for an employer? Should we not aim to revive the household and the neighborhood, as well as the factory and the office,as centers of production and work?The industrial age has been the only period of human history in which most people’s work has taken the form of jobs.The industrial age may now be coming to an end,and some of the changes in work patterns which it brought may have to be reversed.This seems a frustrating thought.But, in fact,it could offer the prospect of a better future for work.Universal employment,as its history shows,has not meant economic freedom.Employment became widespread when the enclosures of the l7th and l8th centuries made many people dependent on paid work by depriving them of the use of the land,and thus of themeans to provide a living for themselves.Then the factory system destroyed the cottage industries and removed work from people’s homes.Later, as transport improved first by rail and then by road,people commuted longer distances to their places of employment until,eventually many people’s work lost all connection with their hom e lives and the places in which they live.Meanwhile,employment put women at a disadvantage.In preindustrial times,men and women had shared the productive work of the household and village community.Now it became customary for the husband to go out to paid employment,leaving the unpaid work of the home and families to his wife.Tax and benefit regulations still assume this norm today,and restrict more flexible sharing of work roles between the sexes.It was not only women whose work status suffered.As employment became the dominant form of work,young people and old people were excluded-a problem now, as more teenagers become frustrated at school and more retired people want to live active lives.All this may now have to change.The time has certainly come to switch some effort and resources away from the idealist goal creating jobs for all,to the urgent practical task of helping many people to manage without full-time jobs.74.What is the main idea of the passage?A.Employment became widespread in the l7th and l8th centuries.B.Unemployment will remain a major problem for industrialized nations.C.The industrial age may now be coming to an end.D.Some efforts and resources should be devoted to helping more people cope with the problem of unemployment.75.Which of the following was NOT mentioned as a factor contributing to the spread of employment?A.The enclosures of the l7th and l8th centuries.B.The development of factories.C.Relief from housework on the part of women.D.Development of modem means of transportation.76.It can be inferred from the passage that .A.most people who have been polled believe that the problem of unemployment may not besolved within a short period of timeB.many farmers lost their land when new railways and factories were being constructed C.in preindustrial societies housework and community service were mainly carried out by womenD.some of the changes in work pattern that the industrial age brought have been reversed 77.Which of the following is NOT suggested as a possible means to cope with the current situation?A.Create situations in which people work for themselves.B.Treat employment as the norm.C.Endeavor to revive the household and the neighborhood as centers of production.D.Encourage people to work in circumstances other than normal working conditions.Section CDirections:Read the passage carefully.Then answer the questions or complete the statements in the fewest possible words.Sarah Alexander celebrated the start of her last year at Wells College the way many other seniors before her have. She ran across the picturesque campus to the shores of Cayuga Lake,where she jumped into the water.So did many of her fellow seniors.But dozens of students decided to stay away, especially the relatively few newly arrived male students.Wells College,which since l868 had educated only women,began accepting men this year in hopes of strengtherring its dwindling enrollment.For many students and alumnae,it was a crushing decision.After the college announced last October that it would go coeducational, about half of the students protested and two filed a lawsuit,which they later dropped.The students-33 men and 383 women—came to campus late month.Both sexes are now trying to navigate the new social landscape.Mr.Phillips said “You can’t do guy stuff.Everv time you want to sit and watch sports or a game,it tulms into a movie.” The women were “somewhat nasty.” I could see the dirty looks in their eyes,” he said.“But I was not going to let that stop me from coming.’’Wells was a place where women didn’t have to worry about their appearance or fight to betaken seriously by their professors.They could enjoy the friendship of their campus sisters and playful traditions.Besides jumping into the lake,the women dance around the maypole each May and kiss the feet of the statue of Minerva,the Roman goddess of wisdom,before exams.Ms.Alexander said,“People told us we wouldn’t notice a difference,but from the moment men arrived on campus not could notice a difference.Women are waking up early to put on makeup,and that’s odd.” she said.Henry Wells,a founder of Wells Fargo and a friend of Cornell’s benefactor, Ezra Cornell established this college,when women were not considered capable of higher learning.“Give her the opportunity,” he wrote.The news that the college would go coed(coeducation)created influence far beyond campus.One alumna wrote a letter to the college’s president,Lisa Marsh Ryerson,saying the founder would make her feel uneasy.“I believe Henry Wells would have done it if I let Wells College close,’’ said Ms.Marsh Ryerson,a Wells alumna herself.The great-great-great-great granddaughter of Henry Wells,Stephanie Redmond,18,of Washingon State,said that earlier this year a Wells student had tracked her down and asked her to support the protest.But Mr.Redmond said the move to admit men had encouraged her to enroll at Wells this year as a freshman.She plans on a career in engineering,a male—dominated field,and said attending an all—women’s college might have put her at a disadvantage.(Note:Answer the questions or complete the statements in NO MORE THAN TEN WORDS.) 78.What is the primary reason for the Wells College to accept men?79.What is the typical behavior for seniors to do?80.The change after turning into a coed college is that .81.The attitude of the author to coeducation is being .第II卷(共47分)I.TranslationDirections:Translate the following sentences into English,using the words given in the brackets.82.生活本应多姿多彩,而非一成不变。

2.答题纸与试卷在试题编号上是一一对应的,答题时应注意,不能错位。

一 阅 读(60分) (一)阅读下文,完成1-5题。

(13分) ①最近几年来,我在许多文章中和发言中,都宣扬一个观点:文化交流是推动人类社会前进的主要动力之一。

我是根据历史事实和现实情况有感而发的,没有丝毫主观成分。

②在这里,关键是一个“交”字,一边倒,向一边流,不能称之为“交流”。

古往今来,地球上不知道有多少国家,多少民族。

几乎每一个民族都有自己的文化创造。

文化不论大小,一旦出现就必然向外流布。

我认为,这可以算是文化的一个特点,全体人类都蒙受了这个特点之利。

如果没有文化交流,我们简直无法想象,今天的中国,今天的世界,文化会是一个什么样子,人民生活水平会是一个什么样子。

③在文化交流方面,中国是一个很有特色的国家。

从蒙昧的远古起,几乎是从一有文化起,中国文化中就有外来的成分。

中国古书上说:“有容乃大”。

中国人民是最“有容”的,我们肯于和善于吸收外来的好东西,不管是精神的,还是物质的,只要对我有利,我们就吸取。

海容百川,所以能成其为大。

我们能吸收各种文化,所以才能创造出这样光辉灿烂的文化。

鲁迅先生提倡“拿来主义”,正表示了这种精神。

④但是,中国不但能“拿来”,我们也能“送去”。

历史上我们不知道有多少伟大的发明创造送到外国去,送给世界人民。

从全世界范围内历史和现状来看,人类文明之所以能发展到今天这样辉煌的程度,中国人民与有力焉。

⑤可惜的是,西方国家自从产业革命以后,科学技术的发展日新月异。

世界上其余的国家都争先恐后地向西方学习。

即以中国而论,我们今天的“楼上楼下,电灯电话”,甚至衣着打扮,从头到脚,哪一件不是从西方来的?中国素以美食名扬全球;然而,就是在这方面,我们也受到了西方的影响。

n﹣3n=(a﹣3)×2n﹣1,a n=S n﹣S n﹣1,n≥2,n∈N*,从而可求得a n=,由a n+1≥a n,可求得a≥﹣9,从而可求得实数a的最小值;(3)由(1)当a=4时,b n=2n﹣1,当n≥2时,C n=3+2+4+…+2n=2n+1+1,C1=3,可证得对正整数n都有C n=2n+1,依题意由t p=2n+1,t p﹣1=2n,(t,p∈N*且t>1,p>1),t只能是不小于3的奇数.分①当p为偶数时与②当p为奇数讨论即可得到答案.解答:解:(1)a n+1=S n+3n⇒S n+1=2S n+3n,b n=S n﹣3n,n∈N*,当a≠3时,===2,所以{b n}为等比数列.b1=S1﹣3=a﹣3,b n=(a﹣3)×2n﹣1.(2)由(1)可得S n﹣3n=(a﹣3)×2n﹣1,a n=S n﹣S n﹣1,n≥2,n∈N*,∴a n=,∵a n+1≥a n,∴a≥﹣9,又a≠3,所以a的最小值为﹣9;(3)由(1)当a=4时,b n=2n﹣1,当n≥2时,C n=3+2+4+…+2n=2n+1+1,C1=3,所以对正整数n都有C n=2n+1.由t p=2n+1,t p﹣1=2n,(t,p∈N*且t>1,p>1),t只能是不小于3的奇数.①当p为偶数时,t p﹣1=(+1)(﹣1)=2n,因为t p+1和t p﹣1都是大于1的正整数,所以存在正整数g,h,使得t p+1=2g,﹣1=2h,2g﹣2h=2,2h(2g﹣h﹣1)=2,所以2h=2且2g﹣h﹣1=1⇒h=1,g=2,相应的n=3,即有C3=32,C3为“指数型和”;②当p为奇数时,t p﹣1=(t﹣1)(1+t+t2+…+t p﹣1),由于1+t+t2+…+t p﹣1是p个奇数之和,仍为奇数,又t﹣1为正偶数,所以(t﹣1)(1+t+t2+…+t p﹣1)=2n不成立,此时没有“指数型和”.点评:本题考查等差数列与等比数列的综合,考查数列求和,突出逻辑思维与创新思维、综合分析、运算能力的考查,属于难题.。

While some flew off to international destinations, the ___41___ majority enjoyed the many tourist sites that China has to offer. If you were one of those people who decided to explore China’s scenic spots, you probably realized that it isn’t just the mountain steps that are steep-the entrance fees are, too!The average cost of the highest ___42___ 5A attractions is 109 yuan. This could prove to be a little too steep for some families, who find themselves spending too large a portion of their holiday budget on admission tickets. The 32 5A locations that upped their prices in the past five years experienced an average ___43___ of over 40 percent. The bad news is that these prices are expected to continue to rise. So how does China’s situation compare t o other parts of the world? The average fees for cultural and historical sites seem to be on par with(与…同价) international ____44__ It’s quite another story, however, when you compare natural wonders. For example, the cost of a ticket to Zhangjiajie National Forest Park hovers around 245 yuan for a three-day tour. This seems ___45_ high when you consider that a week long pass to America’s Yellowstone National Park is a mere 74 yuan. here are ___46__ benefits to increased revenue(收益) from ticket sales, which support necessary ___47_ , maintenance and operation costs. This is especially important for sites that must keep visitor numbers down in order to protect the natural environment. However, it must also be ___48_ that many of China’s tourist attractions are operated by private companies who are ultimately protecting their bottomline(盈亏底线).While the government has put some ___49___ in place, such as only allowing entrance fees to be raised once every three years, they have not ___50___ the upper limit of ticket prices and increases. Further measures to settle the dispute are being considered. In the meantime, some families are forced to re-think if some attractions are really worth the costs.III.

On that day, an uncommon number of tragedies took place. It was also a day when total strangers became linked. The story of Jim Betts and Julio Berumen is a moving example of one such meeting.On that day, Petra Berumen took her daughter Cathy to the dentist. Also in the car was her six-year-old son Julio and their family friend Yolanda. Soon after Petra drove onto the highway, disaster struck. Without warning, the earth began to shake.The damage was terrible. Hugh trees bent as if they were made of rubber. Streets cracked and buildings collapsed. At least a stretch of the highway had crashed onto the lower level.Then as quickly as it started, the earthquake stopped. The Berumens’s car had been crushed b y the steel. Petra and Yolanda were killed instantly. Cathy escaped unhurt but Julio, though still alive, was in danger. Not only was his right leg pinned down by the steel, he was also squeezed between the dead bodies of his mother and Yolanda.Rescuers had calmed Julio by the time Jim Betts, a doctor from Oakland Hospital, arrived. For two hours, Jim tried to free Julio with two bare hands. He did not stop to worry about the fact that aftershocks could send the highway to the ground. As soon as Julio was breathing, Jim kept working. However, Julio was languishing. Jim realized that he had only one choice. He would have to cut the boy’s right leg at the knee. Conditions were far from ideal. It was hot inside the car. Darkness had fallen outside.With great care, Jim started the operation. He had to try risky methods. Finally Julio was free.Those hours on the highway were like a nightmare. Jim said: “If my family members were up there badly hurt, they would urgently need he lp like that.” Though on the day the earthquake tore many things apart, it also brought brave people together.66. The San Francisco earthquake was an uncommon event for Julio and Jim because _________.A. the earth shook violently and suddenlyB. they became linked unexpectedlyC. they neither could see the broken highwayD. they both lost their family members67.

A national newspaper(C)The vast majority of fitness trackers count your steps and are worn around the wrist, but now there’s a device that’s designed to be worn like a necklace and monitors tiny movements to improve your posture.The Fineck device aims to address neck pain by tracking tiny movement, spotting bad habits and suggesting exercises via an accompanying app. Made from silicone(硅)and titanium(钛), Fineck monitors a wearer’s movement, balance and posture thanks to sensors inside. The Mountain View California-based firm says that a high percentage of people suffer from neck pain and associated problems, probably caused by more individuals doing office jobs, which generally involve leaning over computer keyboard.The device contains sensors, several different types of instruments to monitor movement, plus a monitor to shake. It connects to an iOS app via Bluetooth so that wearers can see their bad habits and play “neck training” games. The app warns of health risks and records a user’s activity to build up a customer personal health description. The necklace shakes to give smart advice, such as reminding wearers to sit up straight. The app also allows users to set goals, like many other wearables do. “Fineck is the first wearable device for your neck that tracks your neck activity and warn you when you are in a bad posture for too long. You can also exercise your neck with Fineck’s interactive games.” The company writes on Kickstarter. “No matter where you are and what you are doing at office, on the go, or simply just feeling bored, Fineck will bring you enriched exercise experience through motion sensing games and therapies.”It also claims that it is “the world’s first titanium wearable device”. The metal is widely used in fashion stuff that you can wear or carry to match your clothes because it is lightweight, durable and does not tend to cause allergic(过敏的)reactions. It also offers additional features such as shaking to indicate alerts on a user’s smartphone, but it is not currently clear whether it can also be used like bands, to count steps, and so on.The Fineck has a battery life of around seven days and takes one hour to charge. It is available to pre-order via Kickstarter from $69(£44)and is due to ship in March next year.73. What helps the Fineck device to deal with neck pain?A. An accompanying app.B. A necklaceC. Computer keyboard.D. A remote control74. Besides allowing people to set goals, the iOS app also_____.A. improves your posture and suggests exercisesB. exercise your neck and does office jobsC. alerts you to health risk and records your activityD. counts your steps and addresses neck pain75. Which of the following statements is TRUE?A. The Fineck takes an hour to charge and is available at any time.B. Movie stars like to wear necklace made of silicone to match their clothes.C. The device counts the steps to help wearers to see their bad habits.D. Neck-ache is sometimes caused by using computers too much.76. We can infer from the passage that the Fineck device will_____.A. actually cause allergic reactions.B. enrich your life by providing “neck training” gamesC. monitor a wearer’s movement due to the material it is made ofD. help to correct your improper postures(D)World War II initiated the concept of "total war"--war that involved all, civilians and military alike, in the war effort. This was not really new. Lazare Camot had anticipated it during the French Revolution with his call for "a nation in arms". But never before World War II had nation been required to draw so heavily upon the total human resources available to them. In each country, there was a propaganda effort to portray every person in the state as personally involved in the struggle being waged. In the United States, "Rosie the Riveter" was as much a part of the picture as "G. I. Joe". The German "Rosies" were not as likely as their American counterparts to be working as riveters, butfrom 1942 on, they and their children were to face terrors of war as severe as those experienced by their front-line soldiers. Shivering from fear of being buried alive in the cellars that served as air-raid shelters, they had to emerge from those areas of modest security to extinguish the fire bombs that sizzled in the attics above before entire houses were incinerated. Each explosive bomb that fell could mean life or death for each person who heard it coming, depending on where it fell and how big it was.There is no rational way of rendering judgment on the moral aspects of the Allied bombing. It did, of course, kill Nazis and anti-Nazis alike; women and children as well as men; prisoners of war and foreign workers as well as Germans; professors, artists, musicians, and farmers, as well as workers in munitions factories. And the mode of death, as will be seen, was often shocking and gruesome. But it is faulty to assume that without the bombing all those who perished would have survived and would have met death more peacefully. Land invasion would have meant the ravaging of cities by heavy artillery, tanks, and flame throwers, the desperate flight of thousands of civilians (which indeed occurred on Germany's eastern front), and the ultimate collapse of all forces of order, with internecine fighting, famine, and disease as likely accompaniments. Neither can one assume that more churches, famous monuments, paintings, library books, and so forth would have survived. That those who dropped the bombs had pangs of guilt in respect to the suffering they caused and the cultural wealth they destroyed is a credit to their humanitarian sensitivities. But sentiments of revulsion are more appropriately directed at war itself, which inevitably brutalizes those involved, destroys normal sensitivities, and opens the way to rape, pillage, and want of destruction. A "clean", "humane" war is an impossibility.77. World War II is particular in that it _________.A. anticipated the arrival of new age in war-waging.B. victimized the ordinary people and soldiers alike on unprecedented scales.C. made the aggressors suffer more than the aggressed.D. used the propaganda to get the civilians into it without hesitation.78. It can be inferred from the first paragraph that "Rosie the Riveter" was ________.A. a picture used in the war propaganda.B. the name of an American hero during the war.C. a representative of women who were dragged into the war.D. a German-born worker who escaped to America during the war.79. The underlined word in Paragraph 2 most probably means _________.A. terrifyingB. challengingC. appealingD. distracting80. According to the author, without the Allied bombing, __________.A more lives might have been saved.B. people would have died of other disasters.C. the Allied landing would have been out of the questionD. many cultural objects would have survived. IV. Grammar: Fill in the blanks(A)Westminster Abbey, the gothic church, stands in the heart of modern London overlooking the River Thames and Houses of Parliament. It started as a small monastery(修道院), (1)_______ (found) in the year 960 by King Edgar, but soon became one of the most important churches in the kingdom.King Edgar was the first monarch(2)_______ (bury) there in 1065. In the mid 13th Century, King Henry III decided to rebuild it as a great gothic cathedral to rival(与. . . . . .相匹敌)(3)_______ in France.All monarchs have been crowned there(4)_______ William the Conqueror in 1066, and many monarchs have married in the Abbey, most recently Prince William and Catherine Middleton.But Westminster Abbey isn’t just about royalty. Many of the greatest people in British history are buried or commemorated there—artists, scientists, thinkers—there isn’t even a “poet’s corner” built up (5)_______ the grave of 14th-century poet Geoffrey Chaucer.Westminster Abbey tells the story of ordinary British people too. Parts of the Abbey (6) _______ (destroy) in booming raids(空袭)during World War II,(7)_______ services went on throughout the war. On May 8, 1945, the V-E(Victory in Europe)Day, a thanksgiving service was held there. Westminster Abbey stood for courage and British spirit.(8)_______ _______ you are not a Christian, it is impossible not to feel a sense of something otherworldly(超脱尘俗地) when you enter Westminster Abbey—and that goes for tourists, ordinary Londoners, or students getting ready for another Friday at school.(B)What do Leonardo da Vinci, Marie Curie, and Albert Einstein have in common? They were all left-handed, along with other famous people including Barack Obama. In fact, an estimated 13 percent of the world’s population (9)______ be left-handed.Most people are right-handed. This fact also seems to have held true (10)______ history. In 1977, scientists studied works of art made at various times starting with cave drawings from 15,000 B.C. and ending with paintings from the 1950s. Most of the people (11)______ (show) in these works of art are right-handed.Many researchers claim (12)______ (find) relationships between left-handedness and various physical and mental characteristics. However, some of these connections are very weak, and (13) _______ have not been proven. What makes a person become right-handed rather than left-handed? As yet, no one really knows for sure. (14)______ ______ ______ reasons may be behind it, people’s attitudes toward left-handedness have changed a lot over the years. There are even a number of shops (15)______ (specialize) in selling products for left-handed people, such as left-handed scissors, can openers, guitars, and even a left-handed camera. In 1976, Left-Handers International, a group of left-handed people in Topeka, Kansas, in the United States, decided to start (16)______ annual event in order to clear up misunderstandings about left-handedness.。
