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 percent,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 11ctively poor infrastructure of the Midlands and the North.However,over the past 12 months,those commaers Fave also experienced some of the worst rail strikes in years.It is all very well train crerstors 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 pavin;ts trcvel.The responsibility for the latest wave of strikes rests on the unions.However,there is 2 strong case that those who have been worst affected by industrial action should receive compensation for the disruption they have suffered.The Governmentlas 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 willreturn 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 Para.2 is used to stand for[A]car drivers[B]rail traverllers[C]local investors[D]ordinary tax payers 23.It is indicated in Para.3 that 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 strikes 24.If unable to calm down passenger..he railways may have to face[A]the loss of investment[B]the collapse of operatiors[C]a reduction of reveruc[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 Worlk[C]Can Nationalization Bring Hope?[D]Ever-rising Fares Aren’t Sustainable_·1 Text 2 Last 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 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 er.virorn ental degradation,while protecting the environment is sometimes correlated with gr ater poverty.However,those correlations don’t prove cause and effect.The onlv previcus study analyzing causality,based on an area in Mexico that had instituted CCTs,sappcea 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 tc ne gatively affect the environment,though.Ferraro wanted to see if Indonesia’s poverty-alleviaion program was affecting deforestation.Indonesia has the third-largest area of tropical’crect in the world and one of the highest deforestation rates.Ferraro analyzec’s atc!lite 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,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 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 helped preserve traditional lifescy!es[C]antipoverty efforts require the participatiox of!o:ai farmers[D]economic growth tends to cause environmental degradation 28.In his study about Indonesia.Ferrarc intends to find out·[A]its acceptance level ofCCTe[B]its annual rate of pcvey alleviation[C]the relation of CCTs to its forest loss[D]the role ofits forests in climate change 29.According to Ferraro,the CCT program in Indonesia is most valuable in that·1[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 3 As 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 pru dery?)I’ve found quite a few,and-since I started posting them on Twitter—they have bee causing quite a stir.People have been surprised to see evidence that Victorians had fe:a1G could,and did,laugh.They are noting that the Victorians suddenly seem to become norerunan as the hundred-or-so years that separate us fade away through our common exper.ence of laughter.Of course,I need to concede tamy collection of“Smiling Victorians”makes up only a tiny percentage of the vast cata!sgme of photographic portraiture created between 1840 and 1900,the majority of which sliov 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 Victori2isociety,the preserve of the super-rich(and even then,dental hygiene was not guaranteed).A toothy grin(especially when there were gaps cLackene d gnashers)lacked class:drunks,tramps,prostitutes and buffoonish music hall p.rtcrners.night 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 LaD.vho enjoyed a hearty laugh,said that when it came to photographic portraits there coLiu be“nothing more damning than a silly,foolish smile fixed forever”.31.According to Paragraph 1,the author’s posts on Twitter[A]illustrated the development of Victorian photography 1[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 Victorians 32.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 mirror 19th-century social conventions.[D]They are in popular use among historians.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 sho、v thathe disapproval of smiles in pictures was.*[A]a deep-root belief[B]a misguide lattiv de[C]a controversial view[D]a thought-provoking idea 1 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 to view photographs?[C]What made photography develop slowly in the Victorian period?[D]How did smiling in photographs become a post-Victorian norm?Text 4 From 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 pa“be ause of pushback from broadband providers,anti-regulatory conservatives and the courts.A federal appeals court weighed in again Tuesday,but instead of providing a batly nee ded resolution,it only prolonged the fight.At issue before the U.S.Court of Appza’s for the District of Columbia Circuit was the latest take of the Federal Communications Con:mission 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:Dmacratic majority in 2015,but rejected the commission’s authority to require broadbuu providers to do much of anything.The order also declared that state and local governments coulan’t regulate broadband providers either.The commissior aigved 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 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]i ntensify competition with their rival 37.Faced with the demand for net aetrality rules,the FCC·[A]sticks to an out-of-date oider[B]takes an anti-regulzlry stance[C]has issued a specie!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 1[B]It engages in anti-competitive practices.[C]I t 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 B Directions:In the following text,some sentences have been removed Fo:cuestions

points)In the movies and on televisioa,arcficial intelligence(AI)is typically depicted as something sinister that will upend our vay of life.When it comes to AI in business,we often hear about it in relation to automatior and the impending loss of jobs,but in what ways is AI changing companies and the larger econoniy bat 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 Practices Companies 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 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 Marketing Some 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)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 Money Energy companies can use AI to help customers reduce t ieir electricity bills,saving them money while helping the environment.Companies can alo cptimize their own energy use and cut down on the cost of electricity.Insurance coaDrns,meanwhile,can base their premiums on AI models that more accurately access risk.(43)Improved Accuracy"Machine learning ofta nrvides a more reliable form of statistics,which makes data more valuable,"says Winsto1.I:"helps people make smarter decisions.”(44)Protecting and Maintaining Infrastructure A 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)9[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]T here 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 vphe phone...to accomplish something beyond human scale.[G]AI looks at résumés in greater numbers than humans woulc be able to,and selects the more promising candidates.Part C Directions:Read the following te tcarefully and then translate the underlined segments

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 to 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 in 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 countries of Western Europe the numbers of students in higer education doubled within five-vear periods during the decade of the 1960s and doubled agzin in se ven,eight.or 10 vears by the middle of the 1970s.Second,growth obviously affec’≥a the bsolute size both of systems and individual institutions.And third,growth w.s iectel in changes in the proportion of the relevant age group enrolled in institutions of higher education.Each of these manifestations ol growth carried its own peculiar problems in its wake.For example,a high growth rzte p’aced great strains on the existing structures of governance,of administration,and above ailf socialization.When a very large proportion of all the members of an institution are ne v ec uits,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 to 20 members within three or four years,(49)and when the new staff are predominantly young men and women fresh from postgraduate study,。
