The responsibility for the test wave of strikes rests on the wines.However,there is a strong case that those who have been worst affected by industrial action should receive compensation for the disruption they have suffered.The Government has pledged to change the law to introduce a minimum service requirement,so that,even when strikes occur,services can continue to operate.This should from part of a wider package of measures to address the long-running problems on Britain’s railways.Yes,more investment is needed,but passengers will not be willing to pay more indefinitely if they must also endure cramped,unreliable services interrupted by regularchaos when time tables are changed,or planned maintenance is managed incompetently.They threat of nationalization may have been seen off for now,but it will return with a vengeance if the justified anger of passengers is not addressed in short order.21.The author holds that this year's increase in rail passenger fares.[A]has kept pace with inflation.[B]is a big surprise to commuters.[C]remains an unreasonable measure.[D]will ease train operators burden.22.The stockbroker in Paragraph2is used to stand for.[A]rail travelers.[B]car drivers.[C]local investors.[D]ordinary taxpayers.23.It is indicated in Paragraph3that train operators.[A]have suffered huge losses owing to the strikes.[B]have failed to provide an adequate service.[C]are offering compensation to commuters.[D]are trying to repair relations with the unions24.If unable to calm down passengers,the railways may have to face.[A]the loss of investment.[B]the collapse of operations.[C]a reduction of revenue.[D]a change of ownership.25.Which of the following would be the best title for the text?[A]Who Are to Blame for the Strikes?[B]Constant Complaining Doesn't Work[C]Can Nationalization Bring Hope?[D]Ever-rising Fares Aren't SustainableText2Last year marked the third year in a row that Indonesia’s bleak rate deforestation has slowed in pace.One reason for the turnaround may be the country’s antipoverty program.In2007,Indonesia started phasing in a program that gives money to its poorest residents under certain conditions,such as requiring people to keep kids in school or get regular medical care.Called conditional cash transfers or CCTs,these social assistance programs are designed to reduce inequality and break the cycle of poverty.They are already used in dozens of countries worldwide.In Indonesia,the programme has providedenough food and medicine to substantially reduce severe growth problems among children.But the CCT programs don’t generally consider effects on the environment.In fact,poverty alleviation and environmental protection are often viewed as conflicting goals,says Paul Ferraro,an economist at Johns Hopkins University.That’s because economic growth can be correlated with environmental degradation,while protecting the environment is sometimes correlated with greater poverty.However,those correlations don’t prove cause and effect.The only previous study analyzing causality,based on an area in Mexico that had instituted CCTs, supported the traditional view.There,as people got more money,some of them may have more cleared land for cattle to raise for meat,Ferraro says.Such programs do not have to negatively affect the environment,though.Ferraro wanted to see if Indonesia’s poverty-alleviation program was affecting deforestation.Indonesia has the third-largest area of tropical forest in the world and one of the highest deforestation rates.Ferraro analyzed satellite data showing annual forest loss from2008to2012—including during Indonesia’s phase-in of the antipoverty program—in7,468forested villages across15provinces.“We see that the program is associated with a30percent reduction in deforestation,”Farrow says.That’s likely because the rural poor are using the money as makeshift insurance policies against inclement weather,Ferraro says.Typically,if rains are delayed,people may clear land to plant more rice to supplement their harvest.With the CCTs,individuals instead can use the money to supplement their harvests.Whether this research translates elsewhere is anybody’s guess.Farrow suggests the results may transfer to other parts of Asia,due to commonalities such as the importance of growing rice and market access.And regardless of transferability,the study shows that what’s good for people may also be good for the environment. Even if this program didn’t reduce poverty.Ferraro says,“the value of the avoided deforestation just for carbon dioxide emissions alone is more than the program costs”26.According to the first paragraph,CCT programmes aim to____.[A]Facilitate health-care reform[B]help poor families get better off[C]Improve local education systems[D]lower deforestation rates27.The study based on an area in Mexico excited to show that____.[A]cattle raising has been a major livelihood for the poor[B]CCT programs have helped preserve traditional lifestyles[C]antipoverty efforts require the participation of local farmers[D]economic growth tends to cause environmental degradation28.In his study about Indonesia,Farrow intends to find out____.[A]its acceptance level of CCTs[B]its annual rate of poverty alleviation[C]the relation of CCTs to its forest loss[D]the role of its forests in climate change29.According to Ferraro,the CCT program in Indonesia is valuable in that____.[A]it will benefit other Asian countries[B]it will reduce regional inequality[C]it can protect the environment[D]it can benefit grain production30.What is the text centred on?[A]The effects of a program.[B]The debates over a program.[C]The process of a study.[D]The transfer-ability of a study.Text3As a historian who’s always searching for the test or the image that makes us re-evaluate the past.I’ve become preoccupied with looking for photographs that show our Victorian ancestors smiling(what better way to shatter the image of19th-century prudery?).I’ve found quite a few,and—since I started posting them on Twitter —they have been causing quite stir.People have been surprised to see evidence that Victorian had fun and could, and did,laugh.They are nothing that the Victorians suddenly seem to become more human as the hundred-or-so years that separate us fade away through our common experience of laughter.Of course,I need to concede that my collection of'Smiling Victorians’makes up only a tiny percentage of the vast catalogue of photographic portraiture created between1840and1900,the majority of which show sitters posing miserably and stiffly in front of painted backdrops,or staring absently into the middle distance.How do we explain this trend?During the1840s and1850s in the early days of photography,exposure times were notoriously long:the daguerreotype photographic method(producing an image on a silvered copper plate)could take several minutes to complete,resulting in blurred images as sitters shifted position or adjusted their limbs.The thought holding a fixed grin as the camera performed its magical duties was too much to contemplate,and so a non-committal blank stare became the norm.But exposure ties were much quicker by the1880s and the introduction of the Box Brownie and other portable cameras meant that,though slow by today’s digital standards,the exposure was almost instantaneous. Spontaneous smiles were relatively easy to capture by the1890s so we must look elsewhere for an explanation of why Victorians still hesitated to smile.One explanation might must be the loss of dignity displayed through a cheesy grin.“Nature gave us lips to conceal our teeth.”ran one popular Victorian saying,alluding to the fact that before the birth of proper dentistry mouths were often in a shocking state of hygiene.A flashing set of healthy and clean,regular“pearly whites”wasa rare sight in Victorian society the preserve of the super-rich(and even then,dental hygiene was not guaranteed).A toothy grin(especially when there were gaps or blackened teeth)lacked class:drunks,tramps and music hall performers might gurn and grin with a smile as wide as Lewis Carroll’s gum-exposing Cheshire Cat,but it was not a becoming look for properly bred persons.Even Mark Twain,a man who enjoyed a heartly laugh,said that when it came photographic portraits there could be“nothing more damning than a silly,foolish smile fixed forever”.31.According to paragraph1,the author’s posts on Twitter____.A.illustrated the development of Victorian photographyB.highlighted social media’s tole in Victorian studiesC.re-evaluated the Victorian’s notion of public imageD.changed people’s impression of the Victorians.32.What does the author say about the Victorian portraits he has collected?A.They are rare among photograph of that ageB.They show effect of different exposure timesC.They mirror19th-century social conventionsD.They are in popular use among historians33.What might have kept the Victorians from smiling pictures in the1890s?A.Their inherent social sensitivenessB.Their tension before the cameraC.Their unhealthy dental conditionD.Their distrust of new inventions34.Mark Twain is quoted to show that the disapproval of smiles in pictures was_____.A.a thought-provoking ideaB.a misguide attitudeC.a controversial viesD.a deep-rotted belief35.Which of the following questions does the text answer?A.Why did most Victorians look stern in photographs?B.When did the Victorians start to view photograph differently?C.What made photograph develop slowly in the Victorian period?D.How did smiling in photograph become a post-Victorian norm?Text4From the early days of broadband advocates for consumers and Web-based companies worried that the cable and phone companies selling broadband connections had the power and incentive to favor affiliated websites over their rivals.That's why there has been such a strong demand for rules that would prevent broadband providersfrom picking winners and losers online,preserving the freedom and innovation from what have been the lifeblood of the Internet.Yet that demand has been almost impossible to fill-in part because of push-back from broadband providers anti-regulatory conservatives and the courts.A federal appeals court unchanged in again.Tuesday,but instead of providing a badly needed resolution.It only prolonged the fight.At issue before the U.S.Court of Appeals for the dirtiness of Columbia Court was the latest take of the Federal Communications(FCC.)on net neutrality,adopted on a party-line vote in2017.The publican penned order not only eliminated the strict net neutrality rules the FCC had adopted.When it had a democratic majority in2015.But rejected the commission's authority.To require broadband providers to do much of anything.The order also declared that state and local governments couldn't regulate broadband providers either.The Commission argue that other agencies would protect against anti-competitive behavior,such as a broadband-providing conglomerable like ATRT favors its own vide0-stressing service at the expense of Notfish and Appie TO caps on their rivals streaming services but not their own.On Tuesday,the appeals court.Unanimously upheld the2017order deregulating broadband.provides citing a Supreme Court ruling from2005that upheld a similarly deregulating more.But Judge.Patricia Millett rightly argued in a concurring opinion that“the result is unhinged from the realities of modern broadband service”,and said Congress on the Supreme Court could intervene to avoid trapping Internet regulations in technological.In the meantime,the court threw out the FCC’s attempt to block all state rules.On not neutrality,while preserving the Commission's power to prompt individual going on between the Justice Department and California when enacted a tough net neutrally laws in the world of the FCC’s abdication.The endless legal battles and back-and-forth at the FCC cry out for Congress to act.It needs to give the commission explicit authority once and for all to bar broadband providers from meddling in the traffic on their network and to create clear rules protecting openness and innovation online.36.There has long been concern that broadband providers would.A.bring web-based firms under controlB.show partiality in treating clientsC.slow down the traffic on their networkD.intensify competition with their rivals37.Faced with the demand for net neutrality rules,the FCC.A.takes an anti-regulatory stanceB.sticks to an out-of-date orderC.has issued a special resolutionD.has allowed the states to intervene38.What can be learned about AT&T from Paragraph3?A.It engages in anti-competitive practicesB.It protects against unfair competitionC.It is under the FCC’s investigationD.It is in pursuit of quality service39.Judge Patricia Millett argues that the appeals court’s decision.A.focuses on trivialitiesB.conveys an ambiguous message.C.is out of touch with realityD.is at odds with its earlier rulings.40.What does the author argue in the last paragraph?A.Broadband providers'rights should be protectedB.The FCC should be put under strict supervisionC.Rules need to be set to diversify online servicesD.Congress needs to take action to ensure net neutrality.Part BDirections:In the following text,some sentences have been removed.For Questions41-45,choose the most suitable one from the fist A-G to fit into each of the numbered blanks.There are two extra choices,which do not fit in any of the blanks.Mark your answers on ANSWER SHEET.(10points)In the movies and on television,artificial intelligence(AI)is typically depicted as something sinister that will upend our way of life.When it comes to AI in business,we often hear about it in relation to automation and the impending loss of jobs,but in what ways is AI changing companies and the larger economy that don’t involve doom-and-gloom mass unemployment predictions?A recent survey of manufacturing and service industries from Tata Consultancy Services found that companies currently use AI more often in computer-to-computer activities than in automating human activities. Here are a few ways AI is aiding companies without replacing employees:Better hiring practicesCompanies are using artificial intelligence to remove some of the unconscious bias from hiring decisions.“There are experiments that show that,naturally,the results of interviews are much more biased than what AI does,”says Pedro Domingos,author of The Master Algorithm:How the Quest for the Ultimate Learning Machine Will Remake Our World and a computer science professor at the University of Washington.In addition,“(41)”One company that’s doing this is called Blendoor.It uses analytics to help identify where there may be bias in the hiring processMore effective marketingSome AI software can analyze and optimize marketing email subject lines to increase open rates.One company in the UK,Phrasee,claims their software can outperform humans by up to10percent when it comes to email open rates.This can mean millions more in revenue.(42)These are“tools that helppeople use data,not a replacement for people,”says Patrick H.Winston,a professor of artificial intelligence and computer science at MIT.Saving customers moneyEnergy companies can use AI to help customers reduce their electricity bills,saving them money while helping the panies can also optimize their own energy use and cut down on the cost of electricity.Insurance companies,meanwhile,can base their premiums on AI models that more accurately assess risk.Domingos says,“(43)”Improved accuracy“Machine learning often provides a more reliable form of statistics,which makes data more valuable,”says Winston.It"helps people make smarter decisions.”(44)Protecting and maintaining infrastructureA number of companies,particularly in energy and transportation,use AI image processing technology toinspect infrastructure and prevent equipment failure or leaks before they happen.“If they fail first and then you fix them,it’s very expensive,”says Domingos.“(45)”A.AI replaces the boring parts of your job.If you’re doing research,you can have AI go out and look for relevantsources and information that otherwise you just wouldn’t have time for.B.There are also companies like Acquisio,which analyzes advertising performance across multiple channels likeAdwords,Bing and social media and makes adjustments or suggestions about where advertising funds will yield best results.C.One accounting firm,EY,uses an AI system that helps review contracts during an audit.This process,along withemployees reviewing the contracts,is faster and more accurate.D.We’re also giving our customers better channels versus picking up the phone to accomplish something beyondhuman scale.E.You want to predict if something needs attention now and point to where it’s useful for employees to go to.F.AI looks at résumés in greater numbers than humans would be able to,and selects the more promising candidates.G.Before,they might not insure the ones who felt like a high risk or charge them too much,or they would chargethem too little and then it would cost the company money.Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese.Write your answers on the ANSWER SHEET.(10points)World WarⅡwas the watershed event for higher education in modern Western societies.(46)Those societies came out of the war with levels of enrollment that had been roughly constant at3-5%of the relevant age groups during the decades before the war.But after the war,great social and political changes arising out of the successfulwar against Fascism created a growing demand in European and American economies for increasing numbers of graduates with more than a secondary school education.(47)And the demand that rose in those societies for entry to higher education extended to groups and social classes that had not thought of attending a university before the war.These demands resulted in a very rapid expansion of the systems of higher education,beginning in the1960s and developing very rapidly(though unevenly)during the1970s and1980s.The growth of higher education manifests itself in at least three quite different ways,and these in turn have given rise to different sets of problems.There was first the rate of growth:(48)in many counties of Western Europe,the numbers of students in higher education doubled within five-year periods during the1960s and doubled again in seven,eight,or10years by the middle of the1970s.Second,growth obviously affected the absolute size both of systems and individual institutions.And third,growth was reflected in changes in the proportion of the relevant age group enrolled in institutions of higher education.Each of these manifestations of growth carried its own peculiar problems in its wake.For example,a high growth rate placed great strains on the existing structures of governance,of administration,and above all of socialization.When a faculty or department grows from,say,five to20members within three or four years,(49) and when the new staff predominantly young men and women fresh from postgraduate study,they largely define the norms of academic life in that faculty,And if the postgraduate student population also grows rapidly and there is loss of a close apprenticeship relationship between faculty members and students,the student culture becomes the chief socializing force for new postgraduate students,with consequences for the intellectual and academic life of the institution-this was seen in America as well as in France,Italy,West Germany,and Japan.(50)High growth rates increased the chances for academic innovation;they also weakened the forms and processes by which teachers and students are admitted into a community of scholars during periods of stability or slow growth.In the 1960s and1970s,European universities saw marked changes in their governance arrangements,with the empowerment of junior faculty and to some degree of students as well.Section III WritingPart

satellite data showing annual forest loss from2008to2012—including during Indonesia’s phase-in of the antipoverty program—in7,468forested villages across15 provinces and multiple islands.The duo separated the effects of the CCT program on forest loss from other factors,like weather and macroeconomic changes,which were also affecting forest loss.With that,“we see that the program is associated with a30percent reduction in deforestation,”Ferraro says.That’s likely because the rural poor are using the money as makeshift insurance policies against inclement weather,Ferraro says.Typically,if rains are delayed,people may clear land to plant more rice to supplement their harvests.With the CCTs,individuals instead can use the money to supplement their harvests.Whether this research translates elsewhere is anybody’s guess.Ferraro suggests the importance of growing rice and market access.And regardless of transferability,the study shows that what’s good for people may also be good

health care reform[B]help poor families get better off[C]improve local education systems[D]lower deforestation rates27.The study based on an area in Mexico is cited to show that________.[A]cattle rearing has been a major means of livelihood for the poor[B]CCT programs have helped preserve traditional lifestyles[C]antipoverty efforts require the participation of local farmers[D]economic growth

photographs that show our Victorian ancestors smiling(what better way to shatter the image of19th-century prudery?).I’ve found quite a few, and—since I started posting them on Twitter—they have been causing quite a stir.People have been surprised to see evidence that Victorians had fun and could,and did,laugh.They are noting that the Victorians suddenly seem to become more human as the hundred-or-so years that separate us fade away through our common experience of laughter.Of course,I need to concede that my collection of“Smiling Victorians”makes up only a tiny percentage of the vast catalogue of photographic portraiture created between1840and1900,the majority of which show sitters posing miserably and stiffly in front of painted backdrops,or staring absently into the middle distance.How do we explain this trend?During the1840s and1850s,in the early days of photography,exposure times were notoriously long:the daguerreotype photographic method(producing an image on a silvered copper plate)could take several minutes to complete,resulting in blurred images as sitters shifted position or adjusted their limbs.The thought of holding a fixed grin as the camera performed its magical duties was too much to contemplate,and so a non-committal blank stare became the norm.But exposure times were much quicker by the1880s,and the introduction of the Box Brownie and other portable cameras meant that,though slow by today’s digital standards,the exposure was almost instantaneous.Spontaneous smiles were relatively easy to capture by the 1890s,so we must look elsewhere for an explanation of why Victorians still hesitated to smile.One explanation might be the loss of dignity displayed through a cheesy grin.“Nature gave us lips to conceal our teeth,”ran one popular Victorian maxim,alluding to the fact that before the birth of proper dentistry,mouths were often in a shocking state of hygiene.A flashing set of healthy and clean,regular“pearly whites”was a rare sight in Victorian society,the preserve of the super-rich(and even then,dental hygiene was not guaranteed).A toothy grin(especially when there were gaps or blackened gnashers)lacked class:drunks, tramps,prostitutes and buffoonish music hall performers might gurn and grin with a smile as wide as Lewis Carroll’s gum-exposing Cheshire Cat,but it was not a becoming look for properly bred persons.Even Mark Twain,a man who enjoyed a hearty laugh,said that when it came to photographic portraits there could be“nothing more damning than a silly,foolish smile fixed forever”.31.According to Paragraph1,the author’s posts on Twitter________.[A]illustrated the development of Victorian photography[B]highlighted social media’s role in Victorian studies[C]re-evaluated the Victorian’s notion of public image[D]changed people’s impression of the Victorians32.What does the author say about the Victorian portraits he has collected?[A]They are rare among photographs of that age.[B]They show effects of different exposure times.[C]They mirror19th-century social conventions.[D]They are in popular use among historians.33.What might have kept the Victorians from smiling for pictures in the1890s?[A]Their inherent social sensitiveness.[B]Their tension before the camera.[C]Their distrust of new inventions.[D]Their unhealthy dental condition.34.Mark Twain is quoted to show that the disapproval of smiles in pictures was________.[A]a deep-root belief[B]a misguided attitude[C]a controversial view[D]a thought-provoking idea35.Which of the following questions does the text answer?[A]Why did most Victorians look stern in photographs?[B]Why did the Victorians start to view photographs?[C]What made photography develop slowly in the Victorian period?[D]How did smiling in photographs become a post-Victorian norm?Text4From the early days of broadband,advocates for consumers and web-based companies worried that the cable and phone companies selling broadband connections had the power and incentive to favor their own or their partners’websites and services over those of their rivals. That’s why there has been such a strong demand for rules that would prevent broadband providers from picking winners and losers online,preserving the freedom and innovation that have been the lifeblood of the internet.Yet that demand has been almost impossible to fill—in part because of pushback from broadband providers,anti-regulatory conservatives and the courts.A federal appeals court weighed in again Tuesday,but instead of providing a badly needed resolution,it only prolonged the fight.At issue before the U.S.Court of Appeals for the District of Columbia Circuit was the latest take of the Federal Communications Commission on net neutrality,adopted on a party-line vote in2017.The Republican-penned order not only eliminated the strict net neutrality rules the FCC had adopted when it had a Democratic majority in2015,but rejected the commission’s authority to require broadband providers to do much of anything.The order also declared that state and local governments couldn’t regulate broadband providers either.The commission argued that other agencies would protect against anti-competitive behavior, such as a broadband-providing conglomerate like AT&T favoring its own video-streaming service at the expense of Netflix and Apple TV.Yet the FCC also ended the investigations of broadband providers that imposed data caps on their rivals’streaming services but not their own.On Tuesday,the appeals court unanimously upheld the2017order deregulating broadband providers,citing a Supreme Court ruling from2005that upheld a similarly deregulatory move. But Judge Patricia Millett rightly argued in a concurring opinion that"the result is unhinged from the realities of modern broadband service,"and said Congress or the Supreme Court could intervene to"avoid trapping Internet regulation in technological anachronism."In the meantime,the court threw out the FCC’s attempt to block all state rules on net neutrality,while preserving the commission’s power to pre-empt individual state laws that undermine its order.That means more battles like the one now going on between the Justice Department and California,which enacted a tough net neutrality law in the wake of the FCC’s abdication.The endless legal battles and back-and-forth at the FCC cry out for Congress to act.It needs to give the commission explicit authority once and for all to bar broadband providers from meddling in the traffic on their network and to create clear rules protecting openness and innovation online.36.There has long been concern that broadband provides would.[A]bring web-based firms under control[B]slow down the traffic on their network[C]show partiality in treating clients[D]intensify competition with their rivals37.Faced with the demand for net neutrality rules,the FCC.[A]sticks to an out-of-date order[B]takes an anti-regulatory stance[C]has issued a special resolution[D]has allowed the states to intervene38.What can be learned about AT&T from Paragraph3?[A]It protects against unfair competition[B]It engages in anti-competitive practices.[C]It is under the FCC'S investigation.[D]It is in pursuit of quality service.39.Judge Patricia Millett argues that the appeals court's decision.[A]focuses on trivialities[B]conveys an ambiguous message[C]is at odds with its earlier rulings[D]is out of touch with reality40.What does the author argue in the last paragraph?[A]Congress needs to take action to ensure net neutrality.[B]The FCC should be put under strict supervision.[C]Rules need to be set to diversify online services.[D]Broadband providers'rights should be protected.Part BDirections：In the following text,some sentences have been removed.For questions41–45,choose the most suitable one from the list A–G to fit into each of numbered blanks.There are two extra choices,which do not fit in any of the blanks.Mark your answers on the ANSWER SHEET.(10points) In the movies and on television,artificial intelligence(AI)is typically depicted as something sinister that will upend our way of life.When it comes to AI in business,we often hear about it in relation to automation and the impending loss of jobs,but in what ways is AI changing companies and the larger economy that don’t involve doom-and-gloom mass unemployment predictions?A recent survey of manufacturing and service industries from Tata Consultancy Services found that companies currently use AI more often in computer-to-computer activities than in automating human activities.One common application?Preventing electronic security breaches, which,rather than eliminating IT jobs,actually makes those personnel more valuable to employers, because they help firms prevent hacking attempts.Here are a few other ways AI is aiding companies without replacing employees:Better Hiring PracticesCompanies are using artificial intelligence to remove some of the unconscious bias from hiring decisions.“There are experiments that show that,naturally,the results of interviews aremuch more biased than what AI does,”says Domingos.In addition,(41)One company that’s doing this is called Blendoor.It uses analytics to help identify where there may be bias in the hiring process.More Effective MarketingSome AI software can analyze and optimize marketing email subject lines to increase open rates.One company in the UK,Phrasee,claims their software can outperform humans by up to10 percent when it comes to email open rates.This can mean millions more in revenue.(42) ________________These are“tools that help people use data,not a replacement for people,”says Patrick H.Winston,a professor of artificial intelligence and computer science at MIT.Saving Customers MoneyEnergy companies can use AI to help customers reduce their electricity bills,saving them money while helping the panies can also optimize their own energy use and cut down on the cost of electricity.Insurance companies,meanwhile,can base their premiums on AI models that more accurately access risk.(43)Improved Accuracy“Machine learning often provides a more reliable form of statistics,which makes data more valuable,”says Winston.It“helps people make smarter decisions.”(44)Protecting and Maintaining InfrastructureA number of companies,particularly in energy and transportation,use AI image processing technology to inspect infrastructure and prevent equipment failure or leaks before they happen.“If they fail first and then you fix them,it’s very expensive,”says Domingos.“(45)”[A]I replace the boring parts of your job.If you're doing research,you can have AI go out and look for relevant sources and information that otherwise you just wouldn't have time for.[B]One accounting firm,EY,uses an AI system that helps review contracts during an audit.This process,along with employees reviewing the contracts,is faster and more accurate.[C]There are also companies like Acquisio,which analyzes advertising performance across multiple channels like Adwords,Bing and social media and makes adjustments or suggestions about where advertising funds will be most effective.[D]You want to predict if something needs attention now and point to where it’s useful for [employees]to go to.[E]“Before,they might not insure the ones who felt like a high risk or charge them too much,”says Domingos,“or they would charge them too little and then it would cost[the company] money.”[F]We’re also giving our customers better channels versus picking up the phone…to accomplish something beyond human scale.[G]AI looks at résumés in greater numbers than humans would be able to,and selects the more promising candidates.Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese.Your translation should be written neatly on the ANSWER SHEET.(10points)World War II was the watershed event for higher education in modern western societies.(46) Those societies came out of the war with levels of enrollment that had been roughly constant at 3-5%of the relevant age groups during the decades before the war.But after the war,great social and political changes arising out of the successful war against Fascism created a growing demand in European and American economies for increasing numbers of graduates with more than asecondary school education.(47)And the demand that rose in those societies for entry to higher education extended to groups and social classes that had not thought of attending to a university before the war.These demands resulted in a very rapid expansion of the systems of higher education,beginning in the1960s and developing very rapidly though unevenly in the1970s and 1980s.The growth of higher education manifests itself in at least three quite different ways,and these in turn have given rise to different sets of problems.There was first the rate of growth:(48) in many countries of Western Europe the numbers of students in higher education doubled within five-year periods during the decade of the1960s and doubled again in seven,eight,or10years by the middle of the1970s.Second,growth obviously affected the absolute size both of systems and individual institutions.And third,growth was reflected in changes in the proportion of the relevant age group enrolled in institutions of higher education.Each of these manifestations of growth carried its own peculiar problems in its wake.For example,a high growth rate placed great strains on the existing structures of governance,of administration,and above all of socialization.When a very large proportion of all the members of an institution are new recruits,they threaten to overwhelm the processes whereby recruits to a more slowly growing system are inducted into its value system and learn its norms and forms. When a faculty or department grows from,say,five to20members within three or four years,(49) and when the new staff are predominantly young men and women fresh from postgraduate study, they largely define the norms of academic life in that faculty and its standards.And if the postgraduate student population also grows rapidly and there is loss of a close apprenticeship relationship between faculty members and students,the student culture becomes the chief socializing force for new postgraduate students,with consequences for the intellectual and academic life of the institution—this was seen in America as well as in France,Italy,West Germany,and Japan.(50)High growth rates increased the chances for academic innovation;they also weakened the forms and processes by which teachers and students are admitted into acommunity of scholars during periods of stability or slow growth.In the1960s and1970s, European universities saw marked changes in their governance arrangements,with the empowerment of junior faculty and to some degree of students as well.They also saw higher levels of student discontent,reflecting the weakening of traditional forms of academic communities.Section IV WritingPart A51.Directions:One foreign friend of yours has recently graduated from college and intends to find a job in China.Please write an email to him/her to make some suggestions.You should write about100words on the ANSWER SHEET.Do not use your own name in the e“Li Ming”instead.(10points)Part B52.Directions:Write an essay of160-200words based on the pictures below.In your essay,you should1)describe the picture briefly,2)interpret its intended meaning,and3)give your comments.You should write neatly on the ANSWER SHEET.(20points)2021年答案速查表SectionⅠUse of English(10points)1.C2.D3.A4.B5.A6.A7.C8.B9.A10.C11.D12.B13.C14.D15.D16.B17.D18.A19.A20.C SectionⅡReading Comprehension(60points)Part A(40points)Text121.D22.B23.C24.D25.DText226.B27.D28.C29.C30.AText331.D32.A33.D34.A35.AText436.C37.B38.B39.D40.APart B(10points)41.G42.C43.E44.B45.DPart C(10points)46.二次世界大战以后，出现了这样的一些西方国家。

You can see something like,“I know we seem to be moving toward a first quarter commitment here.I have reasons to think that won't work.I'd like to layout my reasoning-Would that be OK?" This gives the person a choice,allowing him to verbally optin.And,assuming he says yes,it will make you feel more confident about voicing your disagreement.44.You might feel your heart racing or your face turning red, but do whatever you can to remain natural in both your words and actions.When your body language communicates reluctance or anxiety,it undercuts the message.It sends a mixed message, and your counterpart gels to choose what signals to read.Deep breaths can help,a can speaking more slowly and deliberately.

Equally,there is a sense that the travails of commuters in the south East,many of whom will face among the biggest rises,have received too much attention compared to those who must endure the relativity poor infrastructure of the Mid lands and the North.However,over the past12months,those commuters have also experienced some of the worst rail strikes in years.It is all very well train operators tmmpeting the improvements they are making to lhe network,but passengers should be able to expect a basic level of service for the substantial sums they are now paying to travel.The responsibility for the test wave of strikes rests on the wines.However,there is a strong case that those who have been worst affected by industrial action should receive compensation for the disruption they have suffered.Tlie Government has pledged to change the law to introduce a minimum service requirement,so thateven? when strikes occur,services can continue to operate This should from

deforestation has slowed in pace.One reason for the turnaround may be the country's antipoverty program.In2007,Indonesia started phasing in a program that gives money to its poorest residents under certain conditions,such as requiring people to keep kids in school or gel regular medical care.Called conditional cash transfers or CCTs,these social assistance programs are designed to reduce inequality and break the cycle of poverty.They are already used in dozens of countries worldwide.In Indonesia.the programme has provided enough food and medicine to substantially reduce severe growth problems among children.But the CCT programs don't generally consider eftects on the environment.In fact,poverty alleviation and environmental protection are often viewed as conflicting goals,says Paul Ferraro,an economist at Johns Hopkins University.That's because economic growth can be correlated with environmental degradation,while protecting the environment is sometimes correlated with greater poverty.However,those correlations don't prove cause and effect. l*hc only previous study analyzing causality,based on an area in Mexico that had instituted CCTs,supported the traditional view.There,as people got more money,some of them may have more cleared land for cattle to raise for meat,Ferraro says.Such programs do not have to negatively affect the environment,though.Ferraro wanted to see if Indonesia's poverty-alleviation program was affecting deforestation.Indonesia has the third-largest area of tropical forest in the world and one of the highest deforestation

always searching for the lest or the image that makes us re-evaluate the past.I've become preoccupied with looking for photographs that show our Victorian ancestors smiling(what bettei'way to shatter the image of19th-century prudery?).I've found quite a few,and—since I started posting them on Twitter一they have been causing quite stir.People have been surprised to see evidence that Victorian had fun and could,and did,laugh. They are nothing that the Victorians suddenly seem to become more human as the hundred-or-so years that separate us fade away through our common experience of laughter.Of course,I need to concede that my collection of'Smiling Victorians‘makes up only a tiny percentage of the vast catalogue of photographic portraiture created between1840and1900,the majority of which show sitters posing miserably and stiffly in front of painted backdrops,or staring absently into the middle distance.How do we explain this trend?During the1840s and1850s in the early days of photography,exposure times were notoriously long:the daguerreotype photographic method(producing an image on a silvered copper plate)could take several minutes to complete,resulting in blurred images as sitters shitted position or adjusted their limbs.The thought holding a fixed grin as the camera performed its magical duties was too much to contemplate,and so a non-committal blank stare became the norm.But exposure ties were much quicker by the1880s and the introduction of the Box Brownie and other portable cameras meant that,though slow by today's digital standards,the exposure was almost instantaneous.Spontaneous smiles were relatively easy to capture by the1890s so we must look elsewhere fbr an explanation of why Victorians still hesitated to smile.One explanation might must be the loss of dignity displayed through a cheesy grin."Nature gave us lips to conceal our teeth.n ran one popular Victorian saying,alluding to the fact that before the birth of proper dentistry mouths were often in a shocking state of hygiene.A flashing set of healthy and clean,regular"pearly whites"was a rare sight in Victorian society the preserve of the super-rich(and even then,dental hygiene was not guaranteed).A toothy grin(especially when there were gaps or blackened teeth)lacked class:drunks,tramps and music hall perfonners might gum and grin with a smile as wide as Lewis Carroll,s gum-exposing Cheshire Cat,but it

When a faculty or department grows from,say,five to20members within three or four years,(49)and when the new staff are predominantly young men and women fresh from postgraduate study,they largely define the norms of academic life in that faculty,And if the postgraduate student population also grows rapidly and there is loss of a close apprenticeship relationship between faculty members and students,the student culture becomes the chief socializing force for new postgraduate students,with consequences for the intellectual and academic life of the institution-this was seen in America as well as in France,Italy,West Germany,and Japan.(50)High growth rates increased the chances for academic innovation，they also weakened the forms and processes by which teachers and students are admitted into a community of scholars during periods of stability or slow growth.In the1960s and 1970s,European universities saw marked changes in their governance anangements,with the empowerment of junior faculty and to some degree of students as well.46.战争结束后，这些社会的入学率在战前的几十年里一直保持在相关年龄段的3-5%。

Mark your answers on the ANSWER SHEET. (40 points)Text 1How can the train operators possibly justify yet another increase to rail passenger fares? It has become a grimly reliable annual ritual: every January the cost of travelling by train rises, imposing a significant extra burden on those who have no option but to use the rail network to get to work or otherwise. This year's rise, an average of 2.7 per cent, may be a fraction lower than last year's, but it is still well above the official Consumer Price Index (CPI) measure of inflation.Successive governments have permitted such increases on the grounds that the cost of investing in and running the rail network should be borne by those who use it, rather than the general taxpayer. Why, the argument goes, should a car-driving pensioner from Lincolnshire have to subsidise the daily commute of a stockbroker from Surrey? Equally there is a sense that the travails of commuters in the South East, many of whom will face among the biggest rises, have received too much attention compared to those who must endure the relatively poor infrastructure of the Midlands and the North.However, over the past 12 months, those commuters have also experienced some of the worst rail strikes in years. It is all very well train operators trumpeting the improvements they are making to the network, but passengers should be able to expect a basic level of service for the substantial sums they are now paying to travel. The responsibility for the latest wave of strikes rests on the unions. However, there is a strong case that those who have been worst affected by industrial action should receive compensation for the disruption they have suffered.The Government has pledged to change the law to introduce a minimum service requirement so that, even when strikes occur, services can continue to operate. This should form part of a wider package of measures to address the long-running problems on Britain's railways. Yes, more investment is needed, but passengers will not be willingto pay more indefinitely if they must also endure cramped, unreliable services, punctuated by regular chaos when timetables are changed, or planned maintenance is managed incompetently. The threat of nationalisation may have been seen off for now, but it will return with a vengeance if the justified anger of passengers is not addressed in short order.21. The author holds that this year's increase in rail passengers' fares _____.[A] will ease train operation's burden.[B] has kept pace with inflation.[C] is a big surprise to commuters.[D] remains an unreasonable measure.22. The stockbroker in Paragraph 2 is used to stand for _____.[A] car drivers[B] rail travelers[C] local investors[D] ordinary taxpayers23. It is indicated in Paragraph 3 that train operators _____.[A] are offering compensations to commuters.[B] are trying to repair relations with the unions.[C] have failed to provide an adequate service.[D] have suffered huge losses owing to the strikes.24. If unable to calm down passengers, the railways may have to face _____.[A] the loss of investment.[B] the collapse of operations.[C] a reduction of revenue[D] a change of ownership.25. Which of the following would be the best title for the text?[A] Who Are to Blame for the Strikes?[B] Constant Complaining Doesn't Work[C] Can Nationalization Bring Hope?[D] Ever-rising Fares Aren't SustainableText 2Last year marked the third year in a row of when Indonesia's bleak rate of deforestation has slowed in pace. One reason for the turnaround may be the country's antipoverty program.In 2007, Indonesia started phasing in program that gives money to its poorest residents under certain conditions, such as requiring people to keep kids in school or get regular medical care. Called conditional cash transfers or CCTs, these social assistance programs are designed to reduce inequality and break the cycle of poverty. They're already used in dozens of countries worldwide. In Indonesia, the program has provided enough food and medicine to substantially reduce severe growth problems among children.But CCT programs don't generally consider effects on the environment. In fact, poverty alleviation and environmental protection are often viewed as conflicting goals, says Paul Ferraro, an economist at Johns Hopkins University.That's because economic growth can be correlated with environmental degradation, while protecting the environment is sometimes correlated with greater poverty. However, those correlations don't prove cause and effect. The only previous study analyzing causality, based on an area in Mexico that had instituted CCTs, supported the traditional view. There, as people got more money, some of them may have more cleared land for cattle to raise for meat, Ferraro says.Such programs do not have to negatively affect the environment, though. Ferraro wanted to see if Indonesia's poverty-alleviation program was affecting deforestation. Indonesia has the third-largest area of tropical forest in the world and one of the highest deforestation rates.Ferraro analyzed satellite data showing annual forest loss from 2008 to 2012-including during Indonesia's phase-in of the antipoverty program-in 7, 468 forested villages across 15 provinces and multiple islands. The duo separated the effects of the CCT program on forest loss from other factors, like weather and macroeconomic changes, which were also affecting forest loss. With that, "we see that the program is associated with a 30 percent reduction in deforestation," Ferraro says.That's likely because the rural poor are using the money as makeshift insurance policies against inclement weather, Ferraro says. Typically, if rains are delayed, peoplemay clear land to plant more rice to supplement their harvests. With the CCTs, individuals instead can use the money to supplement their harvests.Whether this research translates elsewhere is anybody's guess. Ferraro suggests the importance of growing rice and market access. And regardless of transferability, the study shows that what's good for people may also be good for the value of the avoided deforestation just for carbon dioxide emissions alone is more than the program costs.26. According to the first two paragraphs, CCT programs aim to _____.[A] facilitate health care reform.[B] help poor families get better off.[C] improve local education systems.[D] lower deforestation rates.27. The study based on an area in Mexico is cited to show that _____.[A] cattle rearing has been a major means of livelihood for the poor.[B] CCT programs have he helped preserve traditional lifestyles.[C] antipoverty efforts require the participation of local farmers.[D] economic growth tends to cause environmental degradation.28. In his study about Indonesia, Ferraro intends to find out _____.[A] its acceptance level of CCTs.[B] its annual rate of poverty alleviation.[C] the relation of CCTs to its forest loss.[D] the role of its forests in climate change.29. According to Ferraro, the CCT program in Indonesia is most valuable in that _____.[A] it will benefit other Asian countries.[B] it will reduce regional inequality.[C] it can protect the environment.[D] it can boost grain production.30. What is the text centered on?[A] The effects of a program.[B] The debates over a program.[C] The process of a study.[D] The transferability of a study.Text 3As a historian who's always searching for the text or the image that makes us re-evaluate the past, I've become preoccupied with looking for photographs that show our Victorian ancestors smiling (what better way to shatter the image of 19th-century prudery?). I've found quite a few, and—since I started posting them on Twitter—they have been causing quite a stir. People have been surprised to see evidence that Victorians had fun and could, and did, laugh. They are noting that the Victorians suddenly seem to become more human as the hundred-or-so years that separate us fade away through our common experience of laughter.Of course, I need to concede that my collection of 'Smiling Victorians' makes up only a tiny percentage of the vast catalogue of photographic portraiture created between 1840 and 1900, the majority of which show sitters posing miserably and stiffly in front of painted backdrops, or staring absently into the middle distance. How do we explain this trend?During the 1840s and 1850s, in the early days of photography, exposure times were notoriously long: the daguerreotype photographic method (producing an image on a silvered copper plate) could take several minutes to complete, resulting in blurred images as sitters shifted position or adjusted their limbs. The thought of holding a fixed grin as the camera performed its magical duties was too much to contemplate, and so a non-committal blank stare became the norm.But exposure times were much quicker by the 1880s, and the introduction of the Box Brownie and other portable cameras meant that, though slow by today's digital standards, the exposure was almost instantaneous. Spontaneous smiles were relatively easy to capture by the 1890s, so we must look elsewhere for an explanation of why Victorians still hesitated to smile.One explanation might be the loss of dignity displayed through a cheesy grin. "Nature gave us lips to conceal our teeth," ran one popular Victorian maxim, alluding to the fact that before the birth of proper dentistry, mouths were often in a shocking state of hygiene. A flashing set of healthy and clean, regular 'pearly whites' was a rare sight in Victorian society, the preserve of the super-rich (and even then, dental hygiene was not guaranteed).A toothy grin (especially when there were gaps or blackened teeth) lacked class: drunks, tramps, prostitutes and buffoonish music hall performers might gurn and grin with a smile as wide as Lewis Carroll's gum-exposing Cheshire Cat, but it was not a becoming look for properly bred persons. Even Mark Twain, a man who enjoyed a hearty laugh, said that when it came to photographic portraits there could be "nothing more damning than a silly, foolish smile fixed forever".31. According to Paragraph 1, the author's posts on Twitter _____[A] changed people's impression of the Victorians.[B] highlighted social media's role in Victorian studies.[C] re-evaluated the Victorians' notion of public image.[D] illustrated the development of Victorian photography.32. What does author say about the Victorian portraits he has collected?[A] They are in popular use among historians.[B] They are rare among photographs of that age.[C] They mirror 19th-century social conventions.[D] They show effects of different exposure times.33. What might have kept the Victorians from smiling for pictures in the 1890s?[A] Their inherent social sensitiveness.[B] Their tension before the camera.[C] Their distrust of new inventions.[D] Their unhealthy dental condition.34. Mark Twain is quoted to show that the disapproval of smiles in pictures was _____.[A] a deep-root belief.[B] a misguided attitude.[C] a controversial view.[D] a thought-provoking idea.35. Which of the following questions does the text answer?[A] Why did most Victorians look stern in photographs?[B] Why did the Victorians start view photographs?[C] What made photography develop slowly in the Victorian period?[D] How did smiling in photographs become a post-Victorian norm?Text 4From the early days of broadband, advocates for consumers and web-based companies worried that the cable and phone companies selling broadband connections had the power and incentive to favor affiliated websites over their rivals. That's why there has been such a strong demand for rules that would prevent broadband providers from picking winners and losers online, preserving the freedom and innovation that have been the lifeblood of the internet.Yet that demand has been almost impossible to fill—in part because of pushback from broadband providers, anti-regulatory conservatives and the courts. A federal appeals court weighed in again Tuesday, but instead of providing badly needed resolution, it only prolonged the fight. At issue before the U. S. Court of Appeals for the District of Columbia Circuit was the latest take of the Federal Communications Commission (FCC) on net neutrality, adopted on a party-line vote in 2017. The Republican-penned order not only eliminated the strict net neutrality rules the FCC had adopted when it had a Democratic majority in 2015, but rejected the commission's authority to require broadband providers to do much of anything. The order also declared that state and local governments couldn't regulate broadband providers either.The commission argued that other agencies would protect against anti-competitive behavior, such as a broadband-providing conglomerate like AT&T favoring its own video-streaming service at the expense of Netflix and Apple TV. Yet the FCC also ended the investigations of broadband providers that imposed data caps on their rivals' streaming services but not their own.On Tuesday, the appeals court unanimously upheld the 2017 order deregulating broadband providers, citing a Supreme Court ruling from 2005 that upheld a similarly deregulatory move. But Judge Patricia Millett rightly argued in a concurring opinion that "the result is unhinged from the realities of modern broadband service," and said Congress or the Supreme Court could intervene to "avoid trapping Internet regulation in technological anachronism."In the meantime, the court threw out the FCC's attempt to block all state rules on net neutrality, while preserving the commission's power to preempt individual state laws that undermine its order. That means more battles like the one now going on betweenthe Justice Department and California, which enacted a tough net neutrality law in the wake of the FCC's abdication.The endless legal battles and back-and-forth at the FCC cry out for Congress to act. It needs to give the commission explicit authority once and for all to bar broadband providers from meddling in the traffic on their network and to create clear rules protecting openness and innovation online.36. There has long been concern that broadband providers would _____.[A] bring web-based firms under control.[B] slow down the traffic on their network.[C] show partiality in treating clients.[D] intensify competition with their rivals.37. Faced with the demand for net neutrality rules, the FCC _____.[A] sticks to an out-of-date order.[B] takes an anti-regulatory stance.[C] has issued a special resolution.[D] has allowed the states to intervene.38. What can be learned about AT&T from Paragraph 3?[A] It protects against unfair competition.[B] It engages in anti-competitive practices.[C] It is under the FCC's investigation.[D] It is in pursuit of quality service.39. Judge Patricia Millett argues that the appeals court's decision _____.[A] focuses on trivialities.[B] conveys an ambiguous message.[C] is at odds with its earlier rulings.[D] is out of touch with reality.40. What does the author argue in the last paragraph?[A] Congress needs to take action to ensure net neutrality.[B] The FCC should be put under strict supervision.[C] Rules need to be set to diversify online services.[D] Broadband providers' rights should be protected.Part BDirections: In the following text, some sentences have been removed.

When it comes to AI in business, we often hear about it in relation to automation and the impending loss of jobs, but in what ways is AI changing companies and the larger economy that don't involve doom-and-gloom mass unemployment predictions?A recent survey of manufacturing and service industries from Tata Consultancy Services found that companies currently use Al more often in computer-to-computer activities than in automating human activities. One common application? Preventing electronic security breaches, which, rather than eliminating IT jobs, actually makes those personnel more valuable to employers, because they help firms prevent hacking attempts.Here are a few other ways AI is aiding companies without replacing employees: Better hiring practicesCompanies are using artificial intelligence to remove some of the unconscious bias from hiring decisions. "There are experiments that show that, naturally, the results of interviews are much more biased than what AI does," says Pedro Domingos, author of The Master Algorithm: How the Quest for the Ultimate Learning Machine Will Remake Our World and a computer science professor at the University of Washington. (41) ___________. One company that's doing this is called Blendoor. It uses analytics to help identify where there may be bias in the hiring process.More effective marketingSome AI software can analyze and optimize marketing email subject lines to increase open rates. One company in the UK, Phrasee, claims their software can outperform humans by up to 10 percent when it comes to email open rates. This can mean millions more in revenue. (42) _____. There are "tools that help people use data, not a replacement for people," says Patrick H. Winston, a professor of artificial intelligence and computer science at MIT.Saving customers moneyEnergy companies can use AI to help customers reduce their electricity bills saving them money while helping the environment. Companies can also optimize their own energy use and cut down on the cost of electricity. Insurance companies meanwhile, can base their premiums on AI models that more accurately access risk. "Before, they might not insure the ones who felt like a high risk or charge them too much," says Domingos, (43) "__________."Improved accuracy"Machine learning often provides a more reliable form of statistics, which makes data more valuable," says Winston. It "helps people make smarter decisions." (44) _________.Protecting and maintaining infrastructureA number of companies, particularly in energy and transportation, use AI image processing technology to inspect infrastructure and prevent equipment failure or leaks before they happen. "If they fail first and then you fix them, it's very expensive," says Domingos. (45) _________.[A] AI replaces the boring parts of your job. If you're doing research, you can have AIgo out and look for relevant sources and information that otherwise you just wouldn't have time for.[B] One accounting firm, EY, uses an AI system that helps review contracts during anaudit. This process, along with employees reviewing the contracts, is faster and more accurate.[C] There are also companies like Acquisio, which analyzes advertising performanceacross multiple channels like Adwords, Bing and social media and makes adjustments or suggestions about where advertising funds will yield best results.[D] You want to predict if something needs attention now and point to where it's usefulfor employees to go to.[E] Before, they might not insure the ones who felt like a high risk or charge them toomuch, or they would charge them too little and then it would cost [the company] money.[F] We're also giving our customers better channels versus picking up the phone toaccomplish something beyond human scale.[G] AI looks at resumes in greater numbers than humans would be able to, and selectsthe more promising candidates.Part CDirections: Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written neatly on the ANSWER SHEET. (10 points)World War II was the watershed event for higher education in modern Western societies. (46) Those societies came out of the war with levels of enrollment that had been roughly constant at 3-5% of the relevant age groups during the decades before the war. But after the war, great social and political changes arising out of the successful war against Fascism created a growing demand in European and American economies for increasing numbers of graduates with more than a secondary school education. (47) And the demand that rose in those societies for entry to higher education extended to groups and social classes that had not thought of attending a university before the war. These demands resulted in a very rapid expansion of the systems of higher education, beginning in the 1960s and developing very rapidly (though unevenly) during the 1970s and 1980s.The growth of higher education manifests itself in at least three quite different ways, and these in turn have given rise to different sets of problems. There was first the rate of growth: (48) in many counties of Western Europe, the numbers of students in higher education doubled within five-year periods during the 1960s and doubled again in seven, eight or 10 years by the middle of the 1970s. Second growth obviously affected the absolute size both of systems and individual institutions. And third growth was reflected in changes in the proportion of the relevant age group enrolled in institutions of higher education.Each of these manifestations of growth carried its own peculiar problems in its wake. For example, a high growth rate placed great strains on the existing structures of governance, of administration, and above all of socialization. When a faculty or department grows from, say, five to 20 members within three or four years, (49) and when the new staff predominantly young men and women fresh from postgraduate study, they largely define the norms of academic life in that faculty. And if the postgraduate student population also grows rapidly and there is loss of a close apprenticeship relationship between faculty members and students, the student culture becomes the chief socializing force for new postgraduate students, with consequences for the intellectual and academic life of the institution-this was seen in America as well as inFrance, Italy, West Germany, and Japan. (50) High growth rates increased the chances for academic innovation, they also weakened the forms and processes by which teachers and students are admitted into a community of scholars during periods of stability or slow growth. In the 1960s and 1970s, European universities saw marked changes in their governance arrangements, with empowerment of junior faculty and to some degree of students as well.Section ⅢWritingPart A51.

II Reading ComprehensionPart ADirections:Read the following four texts.Answer the questions after each text by choosing[A],[B],[C]or [D].Mark your answers on the ANSWER SHEET.(40points)Text1How can the train operators possibly justify yet another increase to rail passenger fares?It has become a grimly reliable annual ritual:every January the cost of travelling by train rises, imposing a significant extra burden on those who have no option but to use the rail network to get to work or otherwise.This year’s rise,an average of2.7percent,may be a fraction lower than last year’s,but it is still well above the official Consumer Price Index(CPI)measure of inflation.Successive governments have permitted such increases on the grounds that the cost of investing in and running the rail network should be borne by those who use it,rather than the general taxpayer.Why,the argument goes,should a car-driving pensioner from Lincolnshire have to subsidise the daily commute of a stockbroker from Surrey?Equally,there is a sense that the travails of commuters in the South East,many of whom will face among the biggest rises,have received too much attention compared to those who must endure the relatively poor infrastructure of the Midlands and the North.However,over the past12months,those commuters have also experienced some of the worst rail strikes in years.It is all very well train operators trumpeting the improvements they are making to the network,but passengers should be able to expect a basic level of service for the substantial sums they are now paying to travel.The responsibility for the latest wave of strikes rests on the unions.However,there is a strong case that those who have been worst affected by industrial action should receive compensation for the disruption they have suffered.The Government has pledged to change the law to introduce a minimum service requirement so that,even when strikes occur,services can continue to operate.This should form part of a wider package of measures to address the long-running problems on Britain’s railways.Yes,more investment is needed,but passengers will not be willing to pay more indefinitely if they must also endure cramped,unreliable services,punctuated by regular chaos when timetables are changed,or planned maintenance is managed incompetently.The threat of nationalisation may have been seen off for now,but it will return with a vengeance if the justified anger of passengers is not addressed in short order.21.The author holds that this year’s increase in rail passengers fares________.[A]will ease train operation’s burden[B]has kept pace with inflation[C]is a big surprise to commuters[D]remains an unreasonable measure22.The stockbroker in Para.2is used to stand for________.[A]car drivers[B]rail traverllers[C]local investors[D]ordinary tax payers23.It is indicated in Para.3that train operators________.[A]are offering compensations to commuters[B]are trying to repair ralations with the unions[C]have failed to provide an adequate source[D]have suffered huge losses owing to the strikes24.If unable to calm down passengers,the railways may have to face________.[A]the loss of investment[B]the collapse of operations[C]a reduction of revenue[D]a change of ownership25.Which of the following would be the best title for the text?[A]Who Are to Blame for the Strikes?[B]Constant Complaining Doesn’t Worlk[C]Can Nationalization Bring Hope?[D]Ever-rising Fares Aren’t SustainableText2Last year marked the third year in a row of when Indonesia’s bleak rate of deforestation has slowed in pace.One reason for the turnaround may be the country’s antipoverty program.In2007,Indonesia started phasing in a program that gives money to its poorest residents under certain conditions,such as requiring people to keep kids in school or get regular medical care.Called conditional cash transfers or CCTs,these social assistance programs are designed to reduce inequality and break the cycle of poverty.They’re already used in dozens of countries worldwide.In Indonesia,the program has provided enough food and medicine to substantially reduce severe growth problems among children.But CCT programs don’t generally consider effects on the environment.In fact,poverty alleviation and environmental protection are often viewed as conflicting goals,says Paul Ferraro, an economist at Johns Hopkins University.That’s because economic growth can be correlated with environmental degradation,while protecting the environment is sometimes correlated with greater poverty.However,those correlations don’t prove cause and effect.The only previous study analyzing causality,based on an area in Mexico that had instituted CCTs,supported the traditional view.There,as people got more money,some of them may have more cleared land for cattle to raise for meat,Ferraro says.Such programs do not have to negatively affect the environment,though.Ferraro wanted to see if Indonesia’s poverty-alleviation program was affecting deforestation.Indonesia has the third-largest area of tropical forest in the world and one of the highest deforestation rates.Ferraro analyzed satellite data showing annual forest loss from2008to2012—including during Indonesia’s phase-in of the antipoverty program—in7,468forested villages across15 provinces and multiple islands.The duo separated the effects of the CCT program on forest loss from other factors,like weather and macroeconomic changes,which were also affecting forest loss.With that,“we see that the program is associated with a30percent reduction in deforestation,”Ferraro says.That’s likely because the rural poor are using the money as makeshift insurance policies against inclement weather,Ferraro says.Typically,if rains are delayed,people may clear land to plant more rice to supplement their harvests.With the CCTs,individuals instead can use the money to supplement their harvests.Whether this research translates elsewhere is anybody’s guess.Ferraro suggests the importance of growing rice and market access.And regardless of transferability,the study shows that what’s good for people may also be good for the value of the avoided deforestation just for carbon dioxide emissions alone is more than the program costs.”26.According to the first two paragraphs,CCT programs aim to________.[A]facilitate health care reform[B]help poor families get better off[C]improve local education systems[D]lower deforestation rates27.The study based on an area in Mexico is cited to show that________.[A]cattle rearing has been a major means of livelihood for the poor[B]CCT programs have helped preserve traditional lifestyles[C]antipoverty efforts require the participation of local farmers[D]economic growth tends to cause environmental degradation28.In his study about Indonesia,Ferraro intends to find out________.[A]its acceptance level of CCTs[B]its annual rate of poverty alleviation[C]the relation of CCTs to its forest loss[D]the role of its forests in climate change29.According to Ferraro,the CCT program in Indonesia is most valuable in that________.[A]it will benefit other Asian countries[B]it will reduce regional inequality[C]it can protect the environment[D]it can boost grain production30.What is the text centered on?[A]The effects of a program.[B]The debates over a program.[C]The process of a study.[D]The transferability of a study.Text3As a historian,who’s always searching for the text or the image that makes us re-evaluate the past.I’ve become preoccupied with looking for photographs that show our Victorian ancestors smiling(what better way to shatter the image of19th-century prudery?).I’ve found quite a few, and—since I started posting them on Twitter—they have been causing quite a stir.People have been surprised to see evidence that Victorians had fun and could,and did,laugh.They are noting that the Victorians suddenly seem to become more human as the hundred-or-so years that separate us fade away through our common experience of laughter.Of course,I need to concede that my collection of“Smiling Victorians”makes up only a tiny percentage of the vast catalogue of photographic portraiture created between1840and1900,the majority of which show sitters posing miserably and stiffly in front of painted backdrops,or staring absently into the middle distance.How do we explain this trend?During the1840s and1850s,in the early days of photography,exposure times were notoriously long:the daguerreotype photographic method(producing an image on a silvered copper plate)could take several minutes to complete,resulting in blurred images as sitters shifted position or adjusted their limbs.The thought of holding a fixed grin as the camera performed its magical duties was too much to contemplate,and so a non-committal blank stare became the norm.But exposure times were much quicker by the1880s,and the introduction of the Box Brownie and other portable cameras meant that,though slow by today’s digital standards,the exposure was almost instantaneous.Spontaneous smiles were relatively easy to capture by the 1890s,so we must look elsewhere for an explanation of why Victorians still hesitated to smile.One explanation might be the loss of dignity displayed through a cheesy grin.“Nature gave us lips to conceal our teeth,”ran one popular Victorian maxim,alluding to the fact that before the birth of proper dentistry,mouths were often in a shocking state of hygiene.A flashing set of healthy and clean,regular“pearly whites”was a rare sight in Victorian society,the preserve of the super-rich(and even then,dental hygiene was not guaranteed).A toothy grin(especially when there were gaps or blackened gnashers)lacked class:drunks, tramps,prostitutes and buffoonish music hall performers might gurn and grin with a smile as wide as Lewis Carroll’s gum-exposing Cheshire Cat,but it was not a becoming look for properly bred persons.Even Mark Twain,a man who enjoyed a hearty laugh,said that when it came to photographic portraits there could be“nothing more damning than a silly,foolish smile fixed forever”.31.According to Paragraph1,the author’s posts on Twitter________.[A]illustrated the development of Victorian photography[B]highlighted social media’s role in Victorian studies[C]re-evaluated the Victorian’s notion of public image[D]changed people’s impression of the Victorians32.What does the author say about the Victorian portraits he has collected?[A]They are rare among photographs of that age.[B]They show effects of different exposure times.[C]They mirror19th-century social conventions.[D]They are in popular use among historians.33.What might have kept the Victorians from smiling for pictures in the1890s?[A]Their inherent social sensitiveness.[B]Their tension before the camera.[C]Their distrust of new inventions.[D]Their unhealthy dental condition.34.Mark Twain is quoted to show that the disapproval of smiles in pictures was________.[A]a deep-root belief[B]a misguided attitude[C]a controversial view[D]a thought-provoking idea35.Which of the following questions does the text answer?[A]Why did most Victorians look stern in photographs?[B]Why did the Victorians start to view photographs?[C]What made photography develop slowly in the Victorian period?[D]How did smiling in photographs become a post-Victorian norm?Text4From the early days of broadband,advocates for consumers and web-based companies worried that the cable and phone companies selling broadband connections had the power and incentive to favor their own or their partners’websites and services over those of their rivals. That’s why there has been such a strong demand for rules that would prevent broadband providers from picking winners and losers online,preserving the freedom and innovation that have been the lifeblood of the internet.Yet that demand has been almost impossible to fill—in part because of pushback from broadband providers,anti-regulatory conservatives and the courts.A federal appeals court weighed in again Tuesday,but instead of providing a badly needed resolution,it only prolonged the fight.At issue before the U.S.Court of Appeals for the District of Columbia Circuit was the latest take of the Federal Communications Commission on net neutrality,adopted on a party-line vote in2017.The Republican-penned order not only eliminated the strict net neutrality rules the FCC had adopted when it had a Democratic majority in2015,but rejected the commission’s authority to require broadband providers to do much of anything.The order also declared that state and local governments couldn’t regulate broadband providers either.The commission argued that other agencies would protect against anti-competitive behavior, such as a broadband-providing conglomerate like AT&T favoring its own video-streaming service at the expense of Netflix and Apple TV.Yet the FCC also ended the investigations of broadband providers that imposed data caps on their rivals’streaming services but not their own.On Tuesday,the appeals court unanimously upheld the2017order deregulating broadband providers,citing a Supreme Court ruling from2005that upheld a similarly deregulatory move. But Judge Patricia Millett rightly argued in a concurring opinion that"the result is unhinged from the realities of modern broadband service,"and said Congress or the Supreme Court could intervene to"avoid trapping Internet regulation in technological anachronism."In the meantime,the court threw out the FCC’s attempt to block all state rules on net neutrality,while preserving the commission’s power to pre-empt individual state laws that undermine its order.That means more battles like the one now going on between the Justice Department and California,which enacted a tough net neutrality law in the wake of the FCC’s abdication.The endless legal battles and back-and-forth at the FCC cry out for Congress to act.It needs to give the commission explicit authority once and for all to bar broadband providers from meddling in the traffic on their network and to create clear rules protecting openness and innovation online.36.There has long been concern that broadband provides would.[A]bring web-based firms under control[B]slow down the traffic on their network[C]show partiality in treating clients[D]intensify competition with their rivals37.Faced with the demand for net neutrality rules,the FCC.[A]sticks to an out-of-date order[B]takes an anti-regulatory stance[C]has issued a special resolution[D]has allowed the states to intervene38.What can be learned about AT&T from Paragraph3?[A]It protects against unfair competition[B]It engages in anti-competitive practices.[C]It is under the FCC'S investigation.[D]It is in pursuit of quality service.39.Judge Patricia Millett argues that the appeals court's decision.[A]focuses on trivialities[B]conveys an ambiguous message[C]is at odds with its earlier rulings[D]is out of touch with reality40.What does the author argue in the last paragraph?[A]Congress needs to take action to ensure net neutrality.[B]The FCC should be put under strict supervision.[C]Rules need to be set to diversify online services.[D]Broadband providers'rights should be protected.Part BDirections：In the following text,some sentences have been removed.For questions41–45,choose the most suitable one from the list A–G to

been roughly constant at 3-5%of the relevant age groups during the decades before the war.But after the war,great social and political changes arising out of the successful war against Fascism created a growing demand in European and American economies for increasing numbers of graduates with more than asecondary school education.(47)And the demand that rose in those societies for entry to higher education extended to groups and social classes that had not thought of attending to a university before the war.These demands resulted in a very rapid expansion of the systems of higher education,beginning in the1960s and developing very rapidly though unevenly in the1970s and 1980s.The growth of higher education manifests itself in at least three quite different ways,and these in turn have given rise to different sets of problems.There was first the rate of growth:(48) in many countries of Western Europe the numbers of students in higher education doubled within five-year periods during the decade of the1960s and doubled again in seven,eight,or10years by the middle of the1970s.Second,growth obviously affected the absolute size both of systems and individual institutions.And third,growth was reflected in changes in the proportion of the relevant age group enrolled in institutions of higher education.Each of these manifestations of growth carried its own peculiar problems in its wake.For example,a high growth rate placed great strains on the existing structures of governance,of administration,and above all of socialization.When a very large proportion of all the members of an institution are new recruits,they threaten to overwhelm the processes whereby recruits to a more slowly growing system are inducted into its value system and learn its norms and forms. When a faculty or department grows from,say,five to20members within three or four years,(49) and when the new staff are predominantly young men and women fresh from postgraduate study, they largely define the norms of academic life in that faculty and its standards.And if the postgraduate student population also grows rapidly and there is loss of a close apprenticeship relationship between faculty members and students,the student culture becomes the chief socializing force for new postgraduate students,with consequences for the intellectual and academic life of the institution—this was seen in America as well as in France,Italy,West Germany,and Japan.(50)High growth rates increased the chances for academic innovation;they also weakened the forms and processes by which teachers and students are admitted into acommunity of scholars during periods of stability or slow growth.In the1960s and1970s, European universities saw marked changes in their governance arrangements,with the empowerment of junior faculty and to some degree of students as well.They also saw higher levels of student discontent,reflecting the weakening of traditional forms of academic communities.Section IV WritingPart A51.Directions:One foreign friend of yours has recently graduated from college and intends to find a job in China.Please write an email to him/her to make some suggestions.You should write about100words on the ANSWER SHEET.Do not use your own name in the e“Li Ming”instead.(10points)Part B52.Directions:Write an essay of160-200words based on the pictures below.In your essay,you should1)describe the picture briefly,2)interpret its intended meaning,and3)give your comments.You should write neatly on the ANSWER SHEET.(20points)2021年答案速查表SectionⅠUse of English(10points)1.C2.D3.A4.B5.A6.A7.C8.B9.A10.C11.D12.B13.C14.D15.D16.B17.D18.A19.A20.C SectionⅡReading Comprehension(60points)Part A(40points)Text121.D22.B23.C24.D25.DText226.B27.D28.C29.C30.AText331.D32.A33.D34.A35.AText436.C37.B38.B39.D40.APart B(10points)41.G42.C43.E44.B45.DPart C(10points)46.二次世界大战以后，出现了这样的一些西方国家。

II Reading ComprehensionPart ADirections:Read the following four texts.Answer the questions after each text by choosing[A],[B],[C]or [D].Mark your answers on the ANSWER SHEET.(40points)Text1How can the train operators possibly justify yet another increase to rail passenger fares?It has become a grimly reliable annual ritual:every January the cost of travelling by train rises, imposing a significant extra burden on those who have no option but to use the rail network to get to work or otherwise.This year’s rise,an average of2.7percent,may be a fraction lower than last year’s,but it is still well above the official Consumer Price Index(CPI)measure of inflation.Successive governments have permitted such increases on the grounds that the cost of investing in and running the rail network should be borne by those who use it,rather than the general taxpayer.Why,the argument goes,should a car-driving pensioner from Lincolnshire have to subsidise the daily commute of a stockbroker from Surrey?Equally,there is a sense that the travails of commuters in the South East,many of whom will face among the biggest rises,have received too much attention compared to those who must endure the relatively poor infrastructure of the Midlands and the North.However,over the past12months,those commuters have also experienced some of the worst rail strikes in years.It is all very well train operators trumpeting the improvements they are making to the network,but passengers should be able to expect a basic level of service for the substantial sums they are now paying to travel.The responsibility for the latest wave of strikes rests on the unions.However,there is a strong case that those who have been worst affected by industrial action should receive compensation for the disruption they have suffered.The Government has pledged to change the law to introduce a minimum service requirement so that,even when strikes occur,services can continue to operate.This should form part of a wider package of measures to address the long-running problems on Britain’s railways.Yes,more investment is needed,but passengers will not be willing to pay more indefinitely if they must also endure cramped,unreliable services,punctuated by regular chaos when timetables are changed,or planned maintenance is managed incompetently.The threat of nationalisation may have been seen off for now,but it will return with a vengeance if the justified anger of passengers is not addressed in short order.21.The author holds that this year’s increase in rail passengers fares________.[A]will ease train operation’s burden[B]has kept pace with inflation[C]is a big surprise to commuters[D]remains an unreasonable measure22.The stockbroker in Para.2is used to stand for________.[A]car drivers[B]rail traverllers[C]local investors[D]ordinary tax payers23.It is indicated in Para.3that train operators________.[A]are offering compensations to commuters[B]are trying to repair ralations with the unions[C]have failed to provide an adequate source[D]have suffered huge losses owing to the strikes24.If unable to calm down passengers,the railways may have to face________.[A]the loss of investment[B]the collapse of operations[C]a reduction of revenue[D]a change of ownership25.Which of the following would be the best title for the text?[A]Who Are to Blame for the Strikes?[B]Constant Complaining Doesn’t Worlk[C]Can Nationalization Bring Hope?[D]Ever-rising Fares Aren’t SustainableText2Last year marked the third year in a row of when Indonesia’s bleak rate of deforestation has slowed in pace.One reason for the turnaround may be the country’s antipoverty program.In2007,Indonesia started phasing in a program that gives money to its poorest residents under certain conditions,such as requiring people to keep kids in school or get regular medical care.Called conditional cash transfers or CCTs,these social assistance programs are designed to reduce inequality and break the cycle of poverty.They’re already used in dozens of countries worldwide.In Indonesia,the program has provided enough food and medicine to substantially reduce severe growth problems among children.But CCT programs don’t generally consider effects on the environment.In fact,poverty alleviation and environmental protection are often viewed as conflicting goals,says Paul Ferraro, an economist at Johns Hopkins University.That’s because economic growth can be correlated with environmental degradation,while protecting the environment is sometimes correlated with greater poverty.However,those correlations don’t prove cause and effect.The only previous study analyzing causality,based on an area in Mexico that had instituted CCTs,supported the traditional view.There,as people got more money,some of them may have more cleared land for cattle to raise for meat,Ferraro says.Such programs do not have to negatively affect the environment,though.Ferraro wanted to see if Indonesia’s poverty-alleviation program was affecting deforestation.Indonesia has the third-largest area of tropical forest in the world and one of the highest deforestation rates.Ferraro analyzed satellite data showing annual forest loss from2008to2012—including during Indonesia’s phase-in of the antipoverty program—in7,468forested villages across15 provinces and multiple islands.The duo separated the effects of the CCT program on forest loss from other factors,like weather and macroeconomic changes,which were also affecting forest loss.With that,“we see that the program is associated with a30percent reduction in deforestation,”Ferraro says.That’s likely because the rural poor are using the money as makeshift insurance policies against inclement weather,Ferraro says.Typically,if rains are delayed,people may clear land to plant more rice to supplement their harvests.With the CCTs,individuals instead can use the money to supplement their harvests.Whether this research translates elsewhere is anybody’s guess.Ferraro suggests the importance of growing rice and market access.And regardless of transferability,the study shows that what’s good for people may also be good for the value of the avoided deforestation just for carbon dioxide emissions alone is more than the program costs.”26.According to the first two paragraphs,CCT programs aim to________.[A]facilitate health care reform[B]help poor families get better off[C]improve local education systems[D]lower deforestation rates27.The study based on an area in Mexico is cited to show that________.[A]cattle rearing has been a major means of livelihood for the poor[B]CCT programs have helped preserve traditional lifestyles[C]antipoverty efforts require the participation of local farmers[D]economic growth tends to cause environmental degradation28.In his study about Indonesia,Ferraro intends to find out________.[A]its acceptance level of CCTs[B]its annual rate of poverty alleviation[C]the relation of CCTs to its forest loss[D]the role of its forests in climate change29.According to Ferraro,the CCT program in Indonesia is most valuable in that________.[A]it will benefit other Asian countries[B]it will reduce regional inequality[C]it can protect the environment[D]it can boost grain production30.What is the text centered on?[A]The effects of a program.[B]The debates over a program.[C]The process of a study.[D]The transferability of a study.Text3As a historian,who’s always searching for the text or the image that makes us re-evaluate the past.I’ve become preoccupied with looking for photographs that show our Victorian ancestors smiling(what better way to shatter the image of19th-century prudery?).I’ve found quite a few, and—since I started posting them on Twitter—they have been causing quite a stir.People have been surprised to see evidence that Victorians had fun and could,and did,laugh.They are noting that the Victorians suddenly seem to become more human as the hundred-or-so years that separate us fade away through our common experience of laughter.Of course,I need to concede that my collection of“Smiling Victorians”makes up only a tiny percentage of the vast catalogue of photographic portraiture created between1840and1900,the majority of which show sitters posing miserably and stiffly in front of painted backdrops,or staring absently into the middle distance.How do we explain this trend?During the1840s and1850s,in the early days of photography,exposure times were notoriously long:the daguerreotype photographic method(producing an image on a silvered copper plate)could take several minutes to complete,resulting in blurred images as sitters shifted position or adjusted their limbs.The thought of holding a fixed grin as the camera performed its magical duties was too much to contemplate,and so a non-committal blank stare became the norm.But exposure times were much quicker by the1880s,and the introduction of the Box Brownie and other portable cameras meant that,though slow by today’s digital standards,the exposure was almost instantaneous.Spontaneous smiles were relatively easy to capture by the 1890s,so we must look elsewhere for an explanation of why Victorians still hesitated to smile.One explanation might be the loss of dignity displayed through a cheesy grin.“Nature gave us lips to conceal our teeth,”ran one popular Victorian maxim,alluding to the fact that before the birth of proper dentistry,mouths were often in a shocking state of hygiene.A flashing set of healthy and clean,regular“pearly whites”was a rare sight in Victorian society,the preserve of the super-rich(and even then,dental hygiene was not guaranteed).A toothy grin(especially when there were gaps or blackened gnashers)lacked class:drunks, tramps,prostitutes and buffoonish music hall performers might gurn and grin with a smile as wide as Lewis Carroll’s gum-exposing Cheshire Cat,but it was not a becoming look for properly bred persons.Even Mark Twain,a man who enjoyed a hearty laugh,said that when it came to photographic portraits there could be“nothing more damning than a silly,foolish smile fixed forever”.31.According to Paragraph1,the author’s posts on Twitter________.[A]illustrated the development of Victorian photography[B]highlighted social media’s role in Victorian studies[C]re-evaluated the Victorian’s notion of public image[D]changed people’s impression of the Victorians32.What does the author say about the Victorian portraits he has collected?[A]They are rare among photographs of that age.[B]They show effects of different exposure times.[C]They mirror19th-century social conventions.[D]They are in popular use among historians.33.What might have kept the Victorians from smiling for pictures in the1890s?[A]Their inherent social sensitiveness.[B]Their tension before the camera.[C]Their distrust of new inventions.[D]Their unhealthy dental condition.34.Mark Twain is quoted to show that the disapproval of smiles in pictures was________.[A]a deep-root belief[B]a misguided attitude[C]a controversial view[D]a thought-provoking idea35.Which of the following questions does the text answer?[A]Why did most Victorians look stern in photographs?[B]Why did the Victorians start to view photographs?[C]What made photography develop slowly in the Victorian period?[D]How did smiling in photographs become a post-Victorian norm?Text4From the early days of broadband,advocates for consumers and web-based companies worried that the cable and phone companies selling broadband connections had the power and incentive to favor their own or their partners’websites and services over those of their rivals. That’s why there has been such a strong demand for rules that would prevent broadband providers from picking winners and losers online,preserving the freedom and innovation that have been the lifeblood of the internet.Yet that demand has been almost impossible to fill—in part because of pushback from broadband providers,anti-regulatory conservatives and the courts.A federal appeals court weighed in again Tuesday,but instead of providing a badly needed resolution,it only prolonged the fight.At issue before the U.S.Court of Appeals for the District of Columbia Circuit was the latest take of the Federal Communications Commission on net neutrality,adopted on a party-line vote in2017.The Republican-penned order not only eliminated the strict net neutrality rules the FCC had adopted when it had a Democratic majority in2015,but rejected the commission’s authority to require broadband providers to do much of anything.The order also declared that state and local governments couldn’t regulate broadband providers either.The commission argued that other agencies would protect against anti-competitive behavior, such as a broadband-providing conglomerate like AT&T favoring its own video-streaming service at the expense of Netflix and Apple TV.Yet the FCC also ended the investigations of broadband providers that imposed data caps on their rivals’streaming services but not their own.On Tuesday,the appeals court unanimously upheld the2017order deregulating broadband providers,citing a Supreme Court ruling from2005that upheld a similarly deregulatory move. But Judge Patricia Millett rightly argued in a concurring opinion that"the result is unhinged from the realities of modern broadband service,"and said Congress or the Supreme Court could intervene to"avoid trapping Internet regulation in technological anachronism."In the meantime,the court threw out the FCC’s attempt to block all state rules on net neutrality,while preserving the commission’s power to pre-empt individual state laws that undermine its order.That means more battles like the one now going on between the Justice Department and California,which enacted a tough net neutrality law in the wake of the FCC’s abdication.The endless legal battles and back-and-forth at the FCC cry out for Congress to act.It needs to give the commission explicit authority once and for all to bar broadband providers from meddling in the traffic on their network and to create clear rules protecting openness and innovation online.36.There has long been concern that broadband provides would.[A]bring web-based firms under control[B]slow down the traffic on their network[C]show partiality in treating clients[D]intensify competition with their rivals37.Faced with the demand for net neutrality rules,the FCC.[A]sticks to an out-of-date order[B]takes an anti-regulatory stance[C]has issued a special resolution[D]has allowed the states to intervene38.What can be learned about AT&T from Paragraph3?[A]It protects against unfair competition[B]It engages in anti-competitive practices.[C]It is under the FCC'S investigation.[D]It is in pursuit of quality service.39.Judge Patricia Millett argues that the appeals court's decision.[A]focuses on trivialities[B]conveys an ambiguous message[C]is at odds with its earlier rulings[D]is out of touch with reality40.What does the author argue in the last paragraph?[A]Congress needs to take action to ensure net neutrality.[B]The FCC should be put under strict supervision.[C]Rules need to be set to diversify online services.[D]Broadband providers'rights should be protected.Part BDirections：In the following text,some sentences have been removed.For questions41–45,choose the most suitable one from the list A–G to fit into each of numbered blanks.There are two extra choices,which do not fit in any of the blanks.Mark your answers on the ANSWER SHEET.(10points) In the movies and on television,artificial intelligence(AI)is typically depicted as something sinister that will upend our way of life.When it comes to AI in business,we often hear about it in relation to automation and the impending loss of jobs,but in what ways is AI changing companies and the larger economy that don’t involve doom-and-gloom mass unemployment predictions?A recent survey of manufacturing and service industries from Tata Consultancy Services found that companies currently use AI more often in computer-to-computer activities than in automating human activities.One common application?Preventing electronic security breaches, which,rather than eliminating IT jobs,actually makes those personnel more valuable to employers, because they help firms prevent hacking attempts.Here are a few other ways AI is aiding companies without replacing employees:Better Hiring PracticesCompanies are using artificial intelligence to remove some of the unconscious bias from hiring decisions.“There are experiments that show that,naturally,the results of interviews aremuch more biased than what AI does,”says Domingos.In addition,(41)One company that’s doing this is called Blendoor.It uses analytics to help identify where there may be bias in the hiring process.More Effective MarketingSome AI software can analyze and optimize marketing email subject lines to increase open rates.One company in the UK,Phrasee,claims their software can outperform humans by up to10 percent when it comes to email open rates.This can mean millions more in revenue.(42) ________________These are“tools that help people use data,not a replacement for people,”says Patrick H.Winston,a professor of artificial intelligence and computer science at MIT.Saving Customers MoneyEnergy companies can use AI to help customers reduce their electricity bills,saving them money while helping the panies can also optimize their own energy use and cut down on the cost of electricity.Insurance companies,meanwhile,can base their premiums on AI models that more accurately access risk.(43)Improved Accuracy“Machine learning often provides a more reliable form of statistics,which makes data more valuable,”says Winston.It“helps people make smarter decisions.”(44)Protecting and Maintaining InfrastructureA number of companies,particularly in energy and transportation,use AI image processing technology to inspect infrastructure and prevent equipment failure or leaks before they happen.“If they fail first and then you fix them,it’s very expensive,”says Domingos.“(45)”[A]I replace the boring parts of your job.If you're doing research,you can have AI go out and look for relevant sources and information that otherwise you just wouldn't have time for.[B]One accounting firm,EY,uses an AI system that helps review contracts during an audit.This process,along with employees reviewing the contracts,is faster and more accurate.[C]There are also companies like Acquisio,which analyzes advertising performance across multiple channels like Adwords,Bing and social media and makes adjustments or suggestions about where advertising funds will be most effective.[D]You want to predict if something needs attention now and point to where it’s useful for [employees]to go to.[E]“Before,they might not insure the ones who felt like a high risk or charge them too much,”says Domingos,“or they would charge them too little and then it would cost[the company] money.”[F]We’re also giving our customers better channels versus picking up the phone…to accomplish something beyond human scale.[G]AI looks at résumés in greater numbers than humans would be able to,and selects the more promising candidates.Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese.Your translation should be written neatly on the ANSWER SHEET.(10points)World War II was the watershed event for higher education in modern western societies.(46) Those societies came out of the war with levels of enrollment that had been roughly constant at 3-5%of the relevant age groups during the decades before the war.But after the war,great social and political changes arising out of the successful war against Fascism created a growing demand in European and American economies for increasing numbers of graduates with more than asecondary school education.(47)And the demand that rose in those societies for entry to higher education extended to groups and social classes that had not thought of attending to a university before the war.These demands resulted in a very rapid expansion of the systems of higher education,beginning in the1960s and developing very rapidly though unevenly in the1970s and 1980s.The growth of higher education manifests itself in at least three quite different ways,and these in turn have given rise to different sets of problems.There was first the rate of growth:(48) in many countries of Western Europe the numbers of students in higher education doubled within five-year periods during the decade of the1960s and doubled again in seven,eight,or10years by the middle of the1970s.Second,growth obviously affected the absolute size both of systems and individual institutions.And third,growth was reflected in changes in the proportion of the relevant age group enrolled in institutions of higher education.Each of these manifestations of growth carried its own peculiar problems in its wake.For example,a high growth rate placed great strains on the existing structures of governance,of administration,and above all of socialization.When a very large proportion of all the members of an institution are new recruits,they threaten to overwhelm the processes whereby recruits to a more slowly growing system are inducted into its value system and learn its norms and forms. When a faculty or department grows from,say,five to20members within three or four years,(49) and when the new staff are predominantly young men and women fresh from postgraduate study, they largely define the norms of academic life in that faculty and its standards.And if the postgraduate student population also grows rapidly and there is loss of a close apprenticeship relationship between faculty members and students,the student culture becomes the chief socializing force for new postgraduate students,with consequences for the intellectual and academic life of the institution—this was seen in America as well as in France,Italy,West Germany,and Japan.(50)High growth rates increased the chances for academic innovation;they also weakened the forms and processes by which teachers and students are admitted into acommunity of scholars during periods of stability or slow growth.In the1960s and1970s, European universities saw marked changes in their governance arrangements,with the empowerment of junior faculty and to some degree of students as well.They also saw higher levels of student discontent,reflecting the weakening of traditional forms of academic communities.Section IV WritingPart A51.Directions:One foreign friend of yours has recently graduated from college and intends to find a job in China.Please write an email to him/her to make some suggestions.You should write about100words on the ANSWER SHEET.Do not use your own name in the e“Li Ming”instead.(10points)Part B52.Directions:Write an essay of160-200words based on the pictures below.In your essay,you should1)describe the picture briefly,2)interpret its intended meaning,and3)give your comments.You should write neatly on the ANSWER SHEET.(20points)2021年答案速查表SectionⅠUse of English(10points)1.C2.D3.A4.B5.A6.A7.C8.B9.A10.C11.D12.B13.C14.D15.D16.B17.D18.A19.A20.C SectionⅡReading Comprehension(60points)Part A(40points)Text121.D22.B23.C24.D25.DText226.B27.D28.C29.C30.AText331.D32.A33.D34.A35.AText436.C37.B38.B39.D40.APart B(10points)41.G42.C43.E44.B45.DPart C(10points)46.二次世界大战以后，出现了这样的一些西方国家。

一．完形填空答案：1-5CACBA 6-10DBDDA 11-15CBADA 16-20BBAAC答案详解:1．C 本填空考查形容词，此形容词的作用很重要，是对Human resource management 酌直接定位，四个选项的意思也是大相径庭，选项A)necessary 为“必要的”，选项B)dispensable 表示“非必要的、可有可无的”，而选项C)central 表示“核心的、处于中心位置的”，D ）understandable 表示“可以理解的”；要准确定位出本填空的最佳形容词，首先涉及对整个文章主线倾向的把握，即本填空是一个利用同现结构法可以定位的答案。
很显然，文章的首句已经概括了本文的主线观点和倾向，即“美国企业轻视员工和人力资源是错误的”：把握了这一点，本填空所在的原文句子讲述的是：Human resource management is not traditionally seenas 1to the competitive survival of the firm in the United States ．这样四个选项中的最佳选项是最能说明“人力资源管理重要”的形容词，并且文章下一段的首句实际也提示出了本题的答案。
首先排除选项B ）dispensable （非必要的、可有可无的），因为这个词汇与主线倾向完全背离。
选项D ）understandable （可以理解的）也可以排除，因为它表达的意思太轻，远不能承担最佳选项的重任。
因此只能在选项c ）central （核心的、处于中心位置的）和选项A ）necessary （必要的）之间选择，显然C ）central 的含义更准确，因此答案为选项C ）central 。
2．A 本填空考查动词，利用关联结构或者对应成分分析法就可以解出。
本填空的待选动词与hired 形成了明显的关联对应结构，根据此提示线索可知四个选项中A ）rented （租用）最为贴切，所以答案为选项A)rented 。
3．C 本填空考查一个常用结构，从原文信息判断应该表达的意思是“就像……一样”，主要在两个选项中选择：A ）like 和c ）as ，这两个选项都能表达此意思，但从严格的语法角度来看，选项A ）like 一般衔接的都是名词或者词组，而选项c ）as -般衔接句子，从这个角度看，答案应该为选项C ）as 。
4．B 本题需要首先确定填空所在句子的原文意思。
本填空前面的原文已知信息为：The lack of importance ；之后的原文已知信息为：to human resource management;根据我们对文章主题的了解很容易判断出此处要表达的意思是：人力资源管理重要性的缺失；理解了这一点，四个选项中A ）compared (to)表达的是“与……相比较”，C ）detached (to)表达的是“与……分离”，D)entitled (to)表达的是“有资格、有权利”，只有选项B)attached (to)表示的是“附属于，与……有关的”，所以答案为选项B ）attached 。
5．A 本填空涉及选择介词与名词的惯用搭配，答案为A ）in ，second in command 是中文常2020说的“二把手”的意思。
6．D本填空考查名词，并且此名词处于主语的位置，本填空所在句子又是一个主系表结构，即“主语是什么”的概念，所以关键绒索是定位原文的表语信息：a specialized job，off at the edge of the corporate hierarchy，提到了corporate hierarchy（公司的等级制度），如果再对比分析本填空所在句子与前一句，前一句中的原文线索the chief financial officer与The6of head of human resource managements是明显的对应成分，the chief financial officer（首席财务官）是一个职位、职务，那么本填空也应该对应是一个职位和职务，所以四个名词选项中只有D)post（职位、职务）最为合适。
7．B本填空考查动词，首先定位其在原文中的主语和宾语。
主语为The executive（管理者），宾语为一个代词it，继续定位，此代词指代的是前文中的“The post of head of human resource management”；定位出了本填空待选动词的宾语为The post（职位、职务），则本题的答案为选项B）holds表示“占有这个职务”，其他的选项A）supervises（监督）、C）manages （管理）和D）brings（引入、带来）表达的动作均不合适。
8．D本填空考查动词词组，也是分析其在原文中的主语和宾语。
主语为The executive（处于人力资源职位的管理者），宾语为Chief Executive Officer(CEO)，并且还给出了一个与此待选动词词组搭配的介词线索to；综合这些线索，特别是宾语是个职位，答案选择选项D）move up to表示“晋升到CEO的职务”最为合适，其他选项表达的意思均无法合理衔接此处的主语和宾语。
9．D本填空考查上下文的逻辑关系，本填空前面的原文信息均是在阐述：“美国企业中人力资源的不重要，主管人力资源的管理者在企业中地位不突出”；而本填空后面的原文信息则为：in Japan the head of human resource management is central-usually the second most important executive，after the CEO;这里的提示线索second most important（第二重要的）已经说明了前后文逻辑关系为转折，答案选择选项D）However。
10.A本填空选择名词，利用复现结构可以迅速走位答案。
首先本填空所在的句子在阐述：in Japan the head of human resource management is central-usually the second most important executive，after the CEO，即人力资源负责人在日本企业中的地位，仅次于CEO；而之前的原文信息也谈论了在美国企业中人力资源管理者的地位，即：The post of head of human resource managements is usually a specialized job,off at the edge of the corporate hierarchy．在谈论地位时，原文出现了提示线索corporate hierarchy（企业的等级制度），因此答案应该为选项A）hierarchy。
11．C本填空考查一个惯用词组，能与原文线索As a构成惯用搭配的有三个选项，即As a fact （事实上）、As a result（结果）、As a case（作为一个例子，表示举例）；分析上下文我们发现填空后面的原文信息为：problems12when new breakthrough technologies arrive，谈论了“问题的出现”，前文都在谈论“美国企业不重视人力资源”，分析了这些前后文的关系，可选出本题的答案C）As a result（结果）。
12．B本题考查动词，答案选择B）emerge，因为本填空所在句子的意思就是说“问题出现了”(problems12when new breakthrough technologies arrive)，四个选项中只有选项B）emerge表示“出现、浮现”，其他选项均无此意思。
13．A本填空的答案取决于原文句子所要表达的意思，因为本文的首句就说明了If sustainable competitive advantage depends on work force skills,本文的主题涉及的是work force skills，那么在四个选项中how to是最贴切表达skills概念的选项，所以为最佳答案。
14．D本填空考查形容词，一并且这个形容词是对事物进行定性，这样就需要研究其所在句：If American workers,for example,take much longer to learn13to operate new flexible manufacturing stations than workers in Germany(as they do)．这个条件句的原文信息明确阐述了：如果美国工人比德国工人花费更长的时间学习如何操作新型的多用途制造设备，根据这个条件信息就不难判断后面的句子所要表达的意思应该为：这种设备的有效成本在德国比在美国低。
选项B）higher是方向性的错误，而选项A)fewer和C）littler在语法上不正确。
15．A本填空可以利用对应成分分析法来定位答案。
根据本句句首信息，本空要填入的形容词是类似于More time的；四个选项中B）intensive（密集的、集中的）是指程度上的概念，而More time是一个数量上的概念，因此B）intensive并不贴切。
选项D）decisive表示“果断的、决定性的”，用在此处更不合适。
选项C）excessive表示“过分的、过量的”，选项A）extensive有“大量的”之意。
因为More time也并没有表示出“过量的”意思，更接近“大量的”意思，所以比较之下extensive的意思更贴切于More。
16.B本填空考查动词，并且利用关联结构和对应成分分析法就可以解出。
根据后面的信息可知：本填空明显处于一个平行对应结构中，本填空有一个明显的对应提示线索，即creates，依据此提示线索，四个选项中答案为选项B）generates。
17.B本填空考查动词，首先定位其主语和宾语；主语为bottlenecks（瓶颈），而宾语为the speed;把握了这丙个线索就可以排除A)promote（提升）和D）accelerate（加快）；选项C) confine表示的“限制”更多的是指“外力控制自由”，即“监禁”的意思，此处并不合适，所以最佳答案为B）limit（限制、阻碍）。
18.A本题为一个语法题，考查从句，首先要判断本句是定语从句，先行词为the speed，能够与这个先行词搭配的标志词在四个选项中有A）which和B）that，进一步再考虑到介词with的因素，答案最终选定为A）which。
19.A本填空选择名词，该名词处于表语的位置，因此一个关键线索是定位主语，即The result;这个主语加了定冠词the，实际指的就是前文的美国工人的技能有问题造成的结果，那么这个结果一定是负面的。
