cognitive researchers likePiaget,adulthood meant the beginning of an_27_.Piaget argued that once adolescents enter the world of work,their newly acquired ability to form hypotheses allows them to create representations that are too ideal.The_28_of such ideals,without the tempering of the reality of a job or profession,rapidly leads adolescents to become _29_ of the non-idealistic world and to press for reform in a characteristically adolescent way.Piaget said:“True adaptation to society comes_30_when the adolescent reformer attempts to put his ideas to work.”Of course,youthful idealism is often courageous,and no one likes to give up dreams.Perhaps,taken_31_out of context,Piaget’s statement seems harsh.What he was_32_,however,is the way reality can modify idealistic views.Some people refer to such modification as maturity.Piaget argued that attaining and accepting a vocation is one of the best ways to modify idealized views and to mature.As careers and vocations become less available during times of _33_,adolescents may be especially hard hit.Such difficult economic times may leave many adolescents_34_about their roles in society.For this reason,community interventions

this section,you are going to read a passage with ten statements attached to it.Each statement contains information given in one of the paragraphs.Identify the paragraph from which the information is derived.You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking the corresponding letter on Answer Sheet 2.Can societies be rich and green?[A]“If our economies are to flourish,if global poverty is to be eliminated and if the well-being of the world’s people enhanced—not just in this generation but in succeeding generations—we must make sure we take care of the natural environment and resources on which our economic activity depends.”That statement comes not,as you might imagine,from a stereotypicaltree-hugging,save-the-world greenie(环保主义者),but from Gordon Brown,a politician with a reputation for rigour,thoroughness and above all,caution.[B]A surprising thing for the man who runs one of the world’s most powerful economies to say?Perhaps;though in the run-up to the five-year review of the Millennium(千年的)Goals,he is far from alone.The roots of his speech,given in March at the roundtable meeting of environment and energy ministers from the G20 group of nations,stretch back to 1972,and the United Nations Conference on the Human Environment in Stockholm.[C]“The protection and improvement of the human environment is a major issue which affects the well-being of peoples and economic development throughout the world,”read the final declaration from this gathering,the first of a sequence which would lead to the Rio de Janeiro Earth Summit in 1992 and the World Development Summit in Johannesburg three years ago.[D]Hunt through the reports prepared by UN agencies and development groups —many for conferences such as this year’s Millennium Goals review—and you will find that the linkage between environmental protection and economic progress is a common thread.[E]Managing ecosystems sustainably is more profitable than exploitingthem,according to the Millennium Ecosystem Assessment.But finding hard evidence to support the thesis is not so easy.Thoughts turn first to some sort of global statistic,some indicator which would rate the wealth of nations in both economic and environmental terms and show a relationship between the two.[F]If such an indicator exists,it is well hidden.And on reflection,this is not surprising;the single word“environment”has so many dimensions,and there are so many other factors affecting wealth—such as the oil deposits—that teasing out a simple economy-environment relationship would be almost impossible.[G]The Millennium Ecosystem Assessment,a vast four-year global study which reported its initial conclusions earlier this year,found reasons to believe that managing ecosystems sustainably—working with nature rather than against it—might be less profitable in the short term,but certainly brings long-term rewards.[H]And the World Resources Institute(WRI)in its World Resources 2005report,issued at the end of August,produced several such examples from Africa and Asia;it also demonstrated that environmental degradation affects the poor more than the rich,as poorer people derive a much higher proportion of their income directly from the natural resources around them.[I]But there are also many examples of growing wealth by trashing the environment,in rich and poor parts of the world alike,whether through unregulated mineral extraction,drastic water use for agriculture,slash-and-burn farming,orfossil-fuel-guzzling(大量消耗)transport.Of course,such growth may not persist in the long term—which is what Mr.Brown and the Stockholm declaration were both attempting to point out.Perhaps the best example of boom growth and bust decline is the Grand Banks fishery.For almost five centuries a very large supply of cod(鳕鱼)provided abundant raw material for an industry which at its peak employed about 40,000 people,sustaining entire communities in Newfoundland.Then,abruptly,the cod population collapsed.There were no longer enough fish in the sea for the stock to maintain itself,let alone an industry.More than a decade later,there was no sign of the ecosystem re-building itself.It had,apparently,been fished out of existence;and the once mighty Newfoundland fleet now gropes about frantically for crab on the sea floor.[J]There is a view that modern humans are inevitably sowing the seed of a global Grand Banks-style disaster.The idea is that we are taking more out of what you might call the planet’s environmental bank balance than it can sustain;we are living beyond our ecological means.One recent study attempted to calculate the extent of this“ecological overshoot of the human economy”,and found that we are using 1.2 Earth’s-worth of environmental goods and services—the implication being that at some point the debt will be called in,and all those services—the things which the planet does for us for free—will grind to a halt.[K]Whether this is right,and if so where and when the ecological axe will fall,is hard to determine with any precision—which is why governments and financial institutions are only beginning to bring such risks into their economic calculations.It is also the reason why development agencies are not united in their view of environmental issues;while some,like the WRI,maintain that environmental progress needs to go hand-in-hand with economic development,others argue that the priority is to build a thriving economy,and then use the wealth created to tackle environmental degradation.[L]This view assumes that rich societies will invest in environmental care.But is this right?Do things get better or worse as we get richer? Here the Stockholmdeclaration is ambiguous.“In the developing countries,”it says,“most of the environmental problems are caused by under-development.”So it is saying that economic development should make for a cleaner world?Not necessarily;“In the industralised countries,environmental problems are generally related to industrialisation and technological development,”it continues.In other words,poor and rich both over-exploit the natural world,but for different reasons.It’s simply not true that economic growth will surely make our world cleaner.[M]Clearly,richer societies are able to provide environmental improvements which lie well beyond the reach of poorer communities.Citizens of wealthy nations demand national parks,clean rivers,clean air and poison-free food.Theyalso,however,use far more natural resources-fuel,water(all those baths and golf courses)and building materials.[N]A case can be made that rich nations export environmental problems,the most graphic example being climate change.As a country’s wealth grows,so do its greenhouse gas emissions.The figures available will not be completelyaccurate.Measuring emissions is not a precise science, particularly when it comes to issues surrounding land use;not all nations have re-leased up-to-date data,and in any case,emissions from some sectors such as aviation are not included in national statistics.But the data is exact enough for a clear trend to be easily discernible.As countries become richer,they produce more greenhouse gases;and the impact of those gases will fall primarily in poor parts of the world.[O]Wealth is not,of course,the only factor involved.The average Norwegian is better off than the average US citizen,but contributes about half as much to climate change.But could Norway keep its standard of living and yet cut its emissions to Moroccan or even Ethiopian levels?That question,repeated across a dozen environmental issues and across our diverse planet,is what will ultimately determine whether the human race is living beyond its ecological means as it pursues economic revival.36.Examples show that both rich and poor countries exploited the environmentfor economic progress.37.Environmental protection and improvement benefit people all over the world.38.It is not necessarily true that economic growth will make our world cleaner.39.The common theme of the UN reports is the relation between environmental protection and economic growth.40.Development agencies disagree regarding how to tackle environment issues while ensuring economic progress.41.It is difficult to find solid evidence to prove environmental friendliness generates more profits than exploiting the natural environment.42.Sustainable management of ecosystems will prove rewarding in the long run.43.A politician noted for being cautious asserts that sustainable human development depends on the natural environment.44.Poor countries will have to bear the cost for rich nations’economic development.45.One recent study warns us of the danger of the exhaustion of natural resources on Earth.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Interactive television advertising, which allows viewers to use their remote controls to click on advertisements, has been pushed for years. Nearly a decade ago it was predicted that viewers of “Friends”, a popular situation comedy, would soon be able to purchase a sweater like Jennifer Aniston’s with a few taps on their remotecontrol.“It’s been the year of interactive television advertising for the last ten or twelve years,”says Colin Dixon of a digital-media consultancy.So the news that Cablevision, and American cable company, was rolling out interactive advertisements to all its customers on October 6th was greeted with some skepticism. During commercials, an overlay will appear at the bottom of the screen, prompting viewers to press a button to request a free sample or order a catalogue. Cablevision hopes to allow customers to buy things with their remote controls early next year.Television advertising could do with a boost. Spending fell by 10% in the first half of the year. The popularization of digital video recorders has caused advertisers to worry that their commercials will be skipped. Some are turning to the Internet, which is cheaper and offers concrete measurements like click-through rates—especially important at a time when marketing budgets are tight. With the launch of interactive advertising,“many of the dollars that went to the Internet will come back to the TV,”says David Kline of Cablevision. Or so the industry hopes.In theory, interactive advertising can engage viewers in a way that 30-second spots do not. Unilever recently ran an interactive campaign for its Axe deodorant(除臭剂),which kept viewers engaged for more than three minutes on average.The amount spent on interactive advertising on television is still small. Magna, an advertising agency, reckons it will be worth about $138 million this year. That falls far short of the billions of dollars people once expected it to generate. But DirecTV, Comcast and Time Warner Cable have all invested in it. A new effort led by Canoe Ventures, a coalition of leading cable providers, aims to make interactive advertising available across America later this year. BrightLine iTV, Which designs and sells interactive ads, says interest has surged: it expects its revenues almost to triple this year. BSkyB, Britain’s biggest satellite-television service, already provides 9 million customers with interactive ads.Yet there are doubts whether people watching television, a“lean back”medium, crave interaction. Click-through rates have been high so far(around 3-4%, compared with less than 0.3% online), but that may be a result of the novelty. Interactive adsand viewers might not go well together.46.What does Colin Dixon mean by saying“It’s been the year of interactive television advertising for the last ten or twelve years”(Lines 4-5, Para.1)?A)Interactive television advertising will become popular in 10-12 years.B)Interactive television advertising has been under debate for the last decade or so.C)Interactive television advertising is successful when incorporated into situation comedies.D)Interactive television advertising has not achieved the anticipated results.47.What is the public’s response to Cablevision’s planned interactive TV advertising program?A)Pretty positive.B)Totally indifferent.C)Somewhat doubtful.D)Rather critical.48.What is the impact of the wide use of digital video recorders on TV advertising?A)It has made TV advertising easily accessible to viewers.B)It helps advertisers to measure the click-through rates.C)It has placed TV advertising at a great disadvantage.D)It enables viewers to check the sales items with ease.49.What do we learn about Unilever’s interactive campaign?A)It proves the advantage of TV advertising.B)It has done well in engaging the viewers.C)It helps attract investments in the company.D)it has boosted the TV advertising industry.50.How does the author view the hitherto high click-through rates?A)They may be due to the novel way of advertising.B)They signify the popularity of interactive advertising.C)They point to the growing curiosity ofTV viewers.D)They indicate the future direction of media reform.Passage TwoQuestions 51 to 55 are based on the following passage.What can be done about mass unemployment? All the wise heads agree: there’re no quick or easy answers. There’s work to be done, but workers aren’t ready to do it—they’re in the wrong places, or they have the wrong skills, Our problems are “structural,”and will take many years to solve.But don’t bother asking for evidence that justifies this bleak view. There isn’t any. On the contrary, all the facts suggest that high unemployment in America is the result of inadequate demand. saying that there’re no easy answers sounds wise. But it’s actually foolish: our unemployment crisis could be cured very quickly if we had the intellectual clarity and political will to act. In other words, structural unemployment is a fake problem, which mainly serves as an excuse for not pursing real solutions.The fact is job openings have plunged in every major sector, while the number of workers forced into part-time employment in almost all industries has soared. Unemployment has surged in every major occupational category. Only three states. With a combined population not much larger than that of Brooklyn, have unemployment rates below 5%. So the evidence contradicts the claim that we’re mainly suffering from structural unemployment. Why, then, has this claim become so popular?Part of the answer is that this is what always happens during periods of high unemployment—in part because experts and analysts believe that declaring the problem deeply rooted, with no easy answers, makes them sound serious.I’ve been looking at what self-proclaimed experts were saying about unemployment during the Great Depression; it was almost identical to what Very Serious People are saying now. Unemployment cannot be brought down rapidly,declared one 1935 analysis, because the workforce is“unadaptable and untrained. It cannot respond to the opportunities which industry may offer.”A few years later, a large defense buildup finally provided a fiscal stimulus adequate to the economy’s needs—and suddenly industry was eager to employ those“unadaptable and untrained”workers.But now, as then, powerful forces are ideologically opposed to the whole idea of government action on a sufficient scale to jump-start the economy. And that, fundamentally, is why claims that we face huge structural problems have been multiplying: they offer a reason to do nothing about the mass unemployment that is crippling out economy and our society.So what you need to know is that there’s no evidence whatsoever to back these claims. We aren’t suffering from a shortage of needed skills, We’re suffering from a lack of policy resolve. As I said, structural unemployment isn’t a real problem, it’s an excuse—a reason not to act on America’s problems at a time when action is desperately needed.51.What does the author think is the root cause of mass unemployment in America?A)Corporate mismanagement.B)Insufficient demand.C)Technological advances.D)Workers’slow adaptation.52.What does the author think of the experts’claim concerning unemployment?A)Self-evident.B)Thought-provoking.C)Irrational.D)Groundless.53.What does the author say helped bring down unemployment during the Great Depression?A)The booming defense industry.B)The wise heads’benefit package.C)Nationwide training of workers.D)Thorough restructuring of industries.54.What has caused claims of huge structural problems to multiply?A)Powerful opposition to government’s stimulus efforts.B)Very Serious People’s attempt to cripple the economy.C)Evidence gathered from many sectors of the industries.D)Economists’failure to detect the problems in time.55.What is the author’s purpose in writing the passage?A)To testify to the experts’analysis of America’s problems.B)To offer a feasible solution to the structural unemployment.C)To show the urgent need for the government to take action.D)To alert American workers to the urgency for adaptation.Part IV Translation (30minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Each paragraph is marked with a le tter. Answer the questions by marking the corresponding letter on Answer Sh eet 2.The best Retailers Combine Bricks and ClicksA) Retail profits are falling sharply. Stores are closing. Malls are emptying. Th e depressing stories just keep coming. Reading the earnings announcements of large retail stores like Macy's, Nordstorm, and Target is about as uplifting as a tour of an intensive care unit. The internet is apparently taking down yet another industry. Brick and mortar stores (实体店) seem to be going the way of the yellow pages. Sure enough, the Census B ureau just released data showing that online retail sales surged 15.2 percent between the first quarter of 2015 and the first quarter of 2016.B) But before you dump all of your retail stocks, there are more facts you sh ould consider. Looking only at that 15.2 percent "surge" would be misleadin g. It was an increase that was on a small base of 6.9 percent. Even when a ti ny number grows by a large percentage terms, it is often still tiny.C) More than 20 years after the internet was opened to commerce, the Cens us Bureau tells us that brick and mortar sales accounted for 92.3 percent of retail sales in the first quarter of 2016. Their data show that only 0.8 percent of retail sales shifted from offline to online between the beginning of 2015 a nd 2016.D) So, despite all the talk about drone (无人机) deliveries to your doorstep, all the retail executives expressing anxiety o ver consumers going online, and even a Presidential candidate exclaiming th at Amazon has a "huge antitrust problem," the Census data suggest that phys ical retail is thriving. Of course, the closed stores, depressed executives, a nd sinking stocks suggest otherwise. What's the real story?E) Many firms operating brick and mortar stores are in trouble. The retail in dustry is getting "reinvented," as we describe in our new book Matchmarkers . It's standing in the path of what Schumpeter called a gale (大风) of creative destruction. That storm has been brewing for some time, an d as it has reached gale force, most large retailers are searching for a respon se. As the CFO of Macy's put it recently, "We're frankly scratching our heads."F) But it's not happening as experts predicted. In the peak of the dot. com b ubble, brick and mortar retail was one of these industries the internet was going to kill—and quickly. The dot. com bust discredited most predictions of that sort and in the years that followed, conventional retailers' confidence in the future increased as Census continued do report weak online sales. And then the gale hit.G) It is becoming increasingly clear that retail reinvention isn't a simple battl e to the death between bricks and clicks. It is about devising retail models th at work for people who are making increasing use of a growing array of inter net-connected tools to change how they search, shop, and buy. Creative retai lers are using the new technologies to innovate just about everything stores d o from managing inventory, to marketing, to getting paid.H) More than drones dropping a new supply of underwear on your doorstep, Apple's massively successful brick-and-mortar-and-glass retail stores and A mazon's small steps in the same direction are what should keep old-fashioned retailers awake at night. Not to mention the large number of creative new r etailers, like Bonobos, that are blending online and offline experiences in crea tive ways.I) Retail reinvention is not a simple process, and it's also not happening on w hat used to be called "Internet Time." Some internet-driven changes have ha ppened quickly, of course. Craigslist quickly overtook newspaper classified ad s and turned newspaper economics upside down. But many widely anticipate d changes weren't quick, and some haven't really started. With the benefit o f hindsight (后见之明), it looks like the internet will transform the economy at something like th e pace of other great inventions like electricity. B2B commerce, for example, didn't move mainly online by 2005 as many had predicted in 2000, nor eve n by 2016, but that doesn't mean it won't do so over the next few decades.J) But the gale is still blowing. The sudden decline in foot traffic in recent yea rs, even though it hasn't been accompanied by a massive decline in physical sales, is a critical warning. People can shop more efficiently online and the refore don't need to go to as many stores to find what they want. There's a s urplus of physical shopping space for the crowds, which is one reason why st ores are downsizing and closing.K) The rise of the mobile phone has recently added a new level of complexit y to the process of retail reinvention. Even five years ago most people faced a choice. Sit at your computer, probably at home or at the office, search and browse, and buy. Or head out to the mall, or Main Street, look and shop, and buy. Now, just about everyone has a smartphone, connected to the internet a lmost everywhere almost all the time. Even when a retailer gets a customer t o walk in the store, she can easily see if there's a better deal online or at anot her store nearby.L) So far, the main thing many large retailers have done in response to all th is is to open online stores, so people will come to them directly rather than to Amazon and its smaller online rivals. Many are having the same problem that newspapers have had. Even if they get online traffic, they struggle to make e nough money online to compensate for what they are losing offline.M) A few seem to be making this work. Among large traditional retailers, Wa lmart recently reported the best results, leading its stock price to surge, whil e Macy's, Target, and Nordstorm's dropped. Yet Walmart's year-over-year onli ne sales only grew 7 percent, leading its CEO to lament (哀叹),"Growth here is to slow." Part of the problem is that almost two decades after Amazon field the one-click patent, the online retail shopping and buying ex perience is filled with frictions. A recent study graded more than 600 internet retailers on how easy it was for consumers to shop, buy, and pay. Almost half of the sites didn't get a passing grade and only 18 percent got an A or B.N) The turmoil on the ground in physical retail is hard to square with the Ce nsus data. Unfortunately, part of the explanation is that the Census retail d ata are unreliable. Our deep look into those data and their preparation revea led serious problems. It seems likely that Census simply misclassifies a large chunk of online sales. It is certain that the Census procedures, which lump t he online sales of major traditional retailers like Walmart with "non-store ret ailers" like food trucks, can mask major changes in individual retail categorie s. The bureau could easily present their data in more useful ways, but they ha ve chosen not to.O) Despite the turmoil, brick and mortar won't disappear any time soon. Th e big questions are which, if any, of the large traditional retailers will still be on the scene in a decade or two because they have successfully reinvented t hemselves, which new players will operate busy stores on Main Streets and maybe even in shopping malls, and how the shopping and buying experiencewill have changed in each retail category. Investors shouldn't write off brick and mortar. Whether they should bet on the traditional players who run th ose stores now is another matter.36. Although online retailing has existed for some twenty years, nearly half of the internet retailers still fail to receive satisfactory feedback from consumers , according to a recent survey.37. Innovative retailers integrate internet technologies with conventional r etailing to create new retail models.38. Despite what the Census data suggest, the value of physical retail's stock s has been dropping.39. Internet-driven changes in the retail industry didn't take place as quickly as widely anticipated.40. Statistics indicate that brick and mortar sales still made up the lion's sh are of the retail business.41. Companies that successfully combine online and offline business models may prove to be a big concern for traditional retailers.42. Brick and mortar retailers' faith in their business was strengthened whe n the dot. com bubble burst.43. Despite the tremendous challenges from online retailing, traditional retai ling will be here to stay for quite some time.44. With the rise of online commerce, physical retail stores are like to suffer the same fate as the yellow pages.45. The wide use of smartphone has made it more complex for traditional r etailers to reinvent their business.Section CDirections: There are 2 passages in this section. Each passage is followed by s ome questions or unfinished statements. For each of them there are four ch oices marked A), B), C) and D). You should decide on the best choice and ma rk the corresponding letter on Answer Sheet 2 with a single line through the c entre.Passage OneQuestions 46 to 50 are based on the following passage.Professor Stephen Hawking has warned that the creation of powerful artificia l intelligence (AI) will be "either the best, or the worst thing, ever to happen to humanity", and praised the creation of an academic institute dedicate d to researching the future of intelligence as "crucial to the future of our ci vilisation and our species".Hawking was speaking at the opening of the Leverhulme Centre for the Futur e of Inteelgence (LCFI) at Cambridge University, a multi-disciplinary institut e that will attempt to tackle some of the open-ended questions raised by the rapid pace of development in AI research."We spend a great deal of time studying history," Hawking said,"which, let's face it, is mostly the history of stupidity. So it's a welcome chan ge that people are studying instead the future of intelligence."While the world-renowned physicist has often been cautious about AI, risin g concerns that humanity could be the architect of its own destruction if it creates a super-intelligence with a will of its own, he was also quick to high light the positives that AI research can bring."The potential benefits of creating intelligence are huge," he said."We cannot predict what we might achieve when our own minds are amplif ied by AI. Perhaps with the tools of this new technological revolution, we wil l be able to undo some of the damage done to the natural world by the last o ne—industrialisation. And surely we will aim to finally eradicate disease and poverty. And every aspect of our lives will be transformed. In short, succes s in creating AI could be the biggest event in the history of our civilisation."Huw Price, the centre's academic director and the Bertrand Russell professo r of philosophy at Cambridge University, where Hawking is also an academic, said that the centre came about partially as a result of the university's Cent re for Existential Risk. That institute examined a wider range of potential p roblems for humanity, while the LCFI has a narrow focus.AI pioneer Margaret Boden, professor of cognitive science at the University o f Sussex, praised the progress of such discussions. As recently as 2009, she s aid, the topic wasn't taken seriously, even among AI researchers."AI is hugely exciting," she said,"but it has limitations, which present grave dangers given uncritical use."The academic community is not alone in warning about the potential dang ers of AI as well as the potential benefits. A number of pioneers from the tec hnology industry, most famously the entrepreneur Elon Musk, have also ex pressed their concerns about the damage that a super-intelligent AI could d o to humanity.46. What did Stephen Hawking think of artificial intelligence?A) It would be vital to the progress of human civilisation.B) It might be a blessing or a disaster in the making.C) It might present challenges as well as opportunities.D) It would be a significant expansion of human intelligence.47. What did Hawking say about the creation of the LCFI?A) It would accelerate the progress of AI research.B) It would mark a step forward in the AI industry.C) It was extremely important to the destiny of humankind.D) It was an achievement of multi-disciplinary collaboration.48. What did Hawking say was a welcome change in AI research?A) The shift of research focus from the past to the future.B) The shift of research from theory to implementation.C) The greater emphasis on the negative impact of AI.D) The increasing awareness of mankind's past stupidity.49. What concerns did Hawking raise about AI?A) It may exceed human intelligence sooner or later.B) It may ultimately over-amplify the human mind.C) Super-intelligence may cause its own destruction.D) Super-intelligence may eventually ruin mankind.50. What do we learn about some entrepreneurs from the technology industry?A) They are much influenced by the academic community.B) They are most likely to benefit from AI development.C) They share the same concerns about AI as academics.D) They believe they can keep AI under human control.Passage TwoQuestions 51 to 55 are based on the following passage.The market for products designed specifically for older adults could reach $30 billion by next year, and startups (初创公司) want in on the action. What they sometimes lack is feedback from the peo ple who they hope will use their products. So Brookdale, the country's largest owner of retirement communities, has been inviting a few select entrepreneu rs just to move in for a few days, show off their products and hear what the r esidents have to say.That's what brought Dayle Rodriguez,28, all the way from England to the dining room of Brookdale South Bay in To rrance, California. Rodriguez is the community and marketing manager for a company called Sentab. The startup's product, SentabTV, enables older adult s who may not be comfortable with computers to access email, video chat and social media using just their televisions and a remote control."It's nothing new, it's nothing too complicated and it's natural because lots o f people have TV remotes," says Rodriguez.But none of that is the topic of conversation in the Brookdale dining room. I nstead, Rodriguez solicits residents' advice on what he should get on his chee seburger and how he should spend the afternoon. Playing cards was on the a genda, as well as learning to play mahjong (麻将).Rodriguez says it's important that residents here don't feel like he's selling th em something. "I've had more feedback in a passive approach," he says. "Playing pool, playing cards, having dinner, having lunch," all work better "th an going through a survey of question. When they get to know me and to tru st me, knowing for sure I'm not selling them something—there'll be more hon est feedback from them."Rodriguez is just the seventh entrepreneur to move into one of Brookdale's 1,100 senior living communities. Other new products in the program have inclu ded a kind of full-blow dryer and specially designed clothing that allows peopl e with disabilities to dress and undress themselves.Mary Lou Busch,93, agree to try the Sentab system. She tells Rodriguez that it might be good for someone, but not for her."I have the computer and FaceTime, which I talk with my family on," she expl ains. She also has an iPad and a smartphone."So I do pretty much everything I need to do."To be fair, if Rodriguez had wanted feedback from some more technophobic (害怕技术的) seniors, he might have ended up in the wrong Brookdale community. Thi s one is located in the heart of Southern California's aerospace corridor. Man y residents have backgrounds in engineering, business and academic circles.But Rodriguez says he's still learning something important by moving into this Brookdale community: "People are more tech-proficient than we thought." And besides, where else would he learn to play mahjong?51. What does the passage say about the startups?A) They never lose time in upgrading products for seniors.B) They want to have a share of the seniors' goods market.C) They invite seniors to their companies to try their products.D) They try to profit from promoting digital products to seniors.52. Some entrepreneurs have been invited to Brookdale to ______.A) have an interview with potential customersB) conduct a survey of retirement communitiesC) collect residents' feedback on their productsD) show senior residents how to use IT products53. What do we know about SentabTV?A) It is a TV program catering to the interest of the elderly.B) It is a digital TV which enjoys popularity among seniors.C) It is a TV specially designed for seniors to view programs.D) It is a communication system via TV instead of a computer.54. What does Rodriguez say is important in promoting products?A) Winning trust from prospective customers.B) Knowing the likes and dislikes of customers.C) Demonstrating their superiority on the spot.D) Responding promptly to customer feedback.55. What do we learn about the seniors in the Brookdale community?A) Most of them are interested in using the Sentab.B) They are quite at ease with high-tech products.C) They have much in common with seniors elsewhere.D) Most of them enjoy a longer life than average people.Part IV Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage f rom Chinese into English.

For years, nutritionists have recommended that pasta be kept to a 26, to cut calories. prevent fat build-up and stop blood sugar 27 up.The low-carbohydrate food movement gave birth to such diets as the Atkins Paleo and Keto, which advised swapping foods like bread, pasta and potatoes for vegetables, fish and meat. More recently the trend of swapping spaghetti for vegetables has been 28 by clean-eating experts.But now a 29 review and analysis of 30 studies by Canadian researchers found that not only does pasta not cause weight gain, but three meals a week can help people drop more than half a kilogram over four months. The reviewers found that pasta had been unfairly demonized(妖魔化) because it had been30 in with other more, ft-promoting carbohydrates" The study found that pasta didn't 31 to weight gain or increase in body fat, " said lead author Dr John Sievenpiper.

Stores are closing. Malls are emptying. The depressing stories just keep coming. Reading the earnings announcements of large retail stores like Macys, Nordstrom, and Target is about as uplifting as a tour of an and mortar stores (:(i) seem to be going the way of the yellow pages. Sure enough, the Census Bureau just released data showing that online retail sales surged 15.2 percent between the first quarter of 2015 and the first quarter of 2016B)But before you dump all of your retail stocks, there are more facts you should consider Looking only at that 15.2 percent "surge" would be misleading. It was an increase that was on a small base of 6.9 percent. Even when a tiny number grows by a large percentage terms, it is often still tiny.C) More than 20 years after the internet was opened to commerce, the Census Bureau tells us that brick and mortar sales accounted for 92.3 percent of retail sales in the first quarter of 2016. Their data show that only 0.8 percent of retail sales shifted from offline to online between the beginning of 2015 and 2016.D)So, despite all the talk about drone(无人机)deliveries to your doorstep, al he retail executives expressing anxiety over consumers going online, and even a Presidential candidate exclaiming that Amazon has a "huge antitrust problem. "theCensus data suggest that physical retail is thriving. Of course, the closed stores. depressed executives, and sinking stocks suggest otherwise. What's the real story。

Annually, the world generates 1.3 billi on tons of solid waste. This is expected to go up to 2.2 billion by 2025. The d eveloped countries are responsible for 44% of waste, and in the U. S. alone, t he average person throws away their body weight in rubbish every month.B) Conventional wisdom would seem to suggest that companies have no ince ntive to lengthen the life cycle of their products and reduce the revenue the y would get from selling new goods. Yet, more and more businesses are think ing about how to reduce consumer waste. This is partly driven by the rising pr ice of raw materials and metals. It is also partly due to both consumers and c ompanies becoming more aware of the need to protect our environment.C) When choosing what products to buy and which brands to buy from, more and more consumers are looking into sustainability. This is opposed to just p rice and performance they were concerned about in the past. In a survey of 54 of the world's leading brands, almost all of them reported that consume rs are showing increasing care about sustainable lifestyles. At the same time,surveys on consumers in the U.S. and the U. K. show that they also care abo ut minimizing energy use and reducing waste.D) For the most part, consumers control what happens to a product. But so me companies are realizing that placing the burden of recycling entirely on th e consumer is not an effective strategy, especially when tossing something away seems like the easiest and most convenient option.E) Some retailers and manufacturers in the clothing, footwear, and electronic s industries have launched environmental programs. . They want to make thei r customers interested in preserving their products and preventing things that still have value from going to the garbage dump. By offering services to help expand the longevity of their products, they're promising quality and dur ability to consumers, and receiving the reputational gains for being environm entally friendly.F) For example, the Swedish jeans company Nudie Jeans offers free repair at twenty of their shops. Instead of discarding their old worn-out jeans, custome rs bring them in to be renewed. The company even provides mail-order repair kits and online videos, so that customers can learn how to fix a pair of jeans at home. Their philosophy is that extending the life of a pair of jeans is not on ly great for the environment, but allows the consumer to get more value out of their product. When customers do want to toss their pair, they can give th em back to the store ,which will repurpose and resell them. Another clothing company, Patagonia, a high-end outdoor clothing store, follows the same principle. It has partnere d with DIY website iFixit to teach consumers how to repair their clothing, such as waterproof outerwear,' at home. The company also offers a repair progr am for their customers for a modest fee. Currently, Patagonia repairs about 40,000 garments a year in their Reno, Nevada, service center. According to t he company's CEO, Rose Marcario, this is about building a company that care s about the environment. At the same time, offering repair supports the per ceived quality of its products.G) In Brazil, the multinational corporation Adidas has been running a shoe-r ecycling program called “Sustainable Footprint” since 2012. Customers can bri ng shoes of any brand into an Adidas store to be shredded and turned into al ternative fuels for energy creation instead of being burned as trash, They ar e used to fuel cement ovens. To motivate visitors to bring in more old shoes , Adidas Brazil promotes the program in stores by showing videos to educate customers, and it even offers a discount each time a customer brings in an o ld pair of shoes. This boosts the reputation and image of Adidas by making p eople more aware of the company's values.H) Enormous opportunities also lie with e-waste. It is estimated that in 2014 t he world produced some 42 million metric tons of e-waste (discarded electrica l and electronic equipment and its parts) with North America and Europe accounting for 8 and 12 million metric tons respectively. The materials from e-was te include iron, copper, gold, silver, and aluminum- materials that could be r eused, resold, salvaged, or recycled. Together, the value of these metals is es timated to be about $ 52 billion. Electronics giants like Best Buy and Samsung have provided e-waste take-back programs over the past few years, which ai m to refurbish (翻新) old electronic components and parts into new products.I) For other companies interested in reducing waste, helping the environme nt, and providing the sustainable lifestyles that consumers seek, here are so me first steps for building a relationship with customers that focuses on recycl ing and restoring value to products :J) Find partners. If you are a manufacturer who relies on outside distributors, then retailers are the ideal partner for collecting old products. Power tool ma ker DeWalt partners with companies, such as Lowes and Napa Auto Parts, to collect old tools at their stores for recycling. The partnership benefits both si des by allowing unconventional partners (for example, two companies from two different industries) to work together on a specific aspect of the value ch ain, like, in this example, an engine firm with an accessory one.K) Create incentives. Environmental conscientiousness isn't always enough to make customers recycle old goods. For instance, DeWalt discovered that ma ny contractors were holding on to their old tools , even f they no longer worke d, because they were expensive purchases and it was hard to justify bringing them in to recycle. By offering instant discounts worth as much as $ 100, D eWalt launched a trade-in program to encourage people to bring back tools. As a result, DeWalt now reuses those materials to create new products.L) Start with a trial program, and expect to change the details as you go. An y take-back program will likely change over time, depending on what works f or your customers and company goals. Maybe you see low customer particip ation at first, or conversely, so much success that the cost of recycling beco mes too high. Best Buy, for instance, has been bearing the lion's share of e-w aste volume since two of its largest competitors, Amazon and Wal-mart, do n ot have their own recycling programs. Since the launch of its program, Best B uy changed its policy to add a $ 25 fee for recycling old televisions in order to keep the program going.M) Build a culture of collective values with customers. A stronger relationshi p between the retailer/producer and the consumer isn't just about financial in centives. By creating more awareness around your efforts to reduce waste, and by developing a culture of responsibility, repair, and reuse, you can build customer loyalty based on shared values and responsibilities.N) These examples are just the tip of the iceberg, but they demonstrate ho w helping customers get more use of their materials can transform value ch ains and operations. Reducing waste by incorporating used materials into production can cut costs and decrease the price of procurement (采购): less to be procured from the outside and more to be re-utilized from the i nside.O) Companies play a big role in creating a circular economy, in which value i s generating less from extracting new resources and more from getting better use out of the resources we already have——but they must also get custome rs engaged in the process.36. Some companies believe that products' prolonged lifespan benefits both t he environment and customers.37. A survey shows shoppers today are getting more concerned about ener gy conservation and environmental protection when deciding what to buy.38. Companies can build customer loyalty by creating a positive culture of en vironmental awareness.39. When companies launch environmental programs, they will have their bra nd reputation enhanced.40. One multinational company offers discounts to customers who bring in old footwear to be used as fuel.41. Recycling used products can help manufacturers reduce production costs.42. Electronic products contain valuable metals that could be recovered.43. It seems commonly believed that companies are not motivated to prolo ng their products' ifespan.44. It is advisable for companies to partner with each other in product recycli ng.45. Some businesses have begun to realize it may not be effective to let con sumers take full responsibility for recycling.Section CDirections: There are 2 passages in this section. Each passage is followed by s ome questions or unfinished statements. For each of them there are four ch oices marked A), B), C) and D). You should decide on the best choice and ma rk the corresponding letter on Answer Sheet 2 with a single line through the c entre.Passage OneQuestions 46 to 50 are based on the following passage.Effective Friday, Screen Actors Guild-American Federation of Television and R adio Artists ( SAG-AFTRA) has declared a strike against 11 video game publis hers over games that went into production after Feb.17,2015. The companies include some of the heavyweights of the industry, like E lectronic Arts Productions, Insomniac Games, Activision and Disney.The strike comes in light of an unsuccessful 19 months of negotiations after the existing labor contract known as the Interactive Media Agreement expired in late 2014. Overall, the strike is an effort to provide more secondary co mpensation along with other concerns, such as transparency upon hiring t alent and on-set (制作中) safety precautions.The video gaming industry has ballooned in recent years. The Los Angeles Ti mes reports that the industry is in the midst of an intense increase in cash fl ow. In 2015, gaming produced $ 23.5 billion in domestic revenue.But SAG-AFTRA says voice actors don't receive residuals (追加酬金) for their gaming work. Instead, they receive a fixed rate, which is typically about $ 825 for a standard four-hour vocal session. So the voice actors are pushing for the idea of secondary compensation--a performance bonus every time a game sells 2 million copies or download s, or reaches 2 million subscribers, with a cap at 8 million."It's a very small number of games that would trigger this secondary compe nsation issue," said voice actor Crispin Freeman, who's a member of the uni on's negotiating committee."This is an important aspect of what it means to be a freelance (从事自由职业的) performer , who isn't regularly employed every single day working on proj ects."Another major complaint from the actors is the secrecy of the industry." I can't imagine if there's any other acting job in the world where you don't know what show you're in, when you're hired," says voice actor Keythe Farley , who chairs the SAG-AFTRA negotiating committee."And yet that happens every day in the video game world," Farley told report ers during a press conference Friday."I was a main character in Fallout 4, a character by the name of Kellogg, and I never knew that I was doing vocal recording for that game throughout the year and a half.Scott Witlin, the lawyer representing the video game companies, says voice a ctors "represent less than one tenth of 1 percent of the work that goes into m aking a video game." So "even though they're the top craftsmen in their field, " Witlin says,"if we pay them under a vastly different system than the people who do the 9 9.9 percent of the work, that's going to create far more problems for the vide o game companies."46. Why did SAG-AFTRA declare a strike against some video game publisher s?A) The labor contract between them had been violated.B) Its appeal to renegotiate the contract had been rejected.C) It had been cheated repeatedly in the 19 months of talks.D) The negotiations between them had broken down.47. What do we learn from the passage about the video gaming industry?A) It has reaped huge profits in recent years.B) It has become more open and transparent.C) It has attracted many famous voice actors.D) It has invested a lot in its domestic market.48. What are the voice actors demanding?A) More regular employment.B) A non-discriminatory contract.C) Extra pay based on sales revenues.D) A limit on the maximum work hours.49. What does Keythe Farley say about voice actors?A) They are kept in the dark about many details of their job.B) They are discriminated against in the gaming industry.C) They are not paid on a regular basis.D) They are not employed full-time.50. What is the argument of lawyer Scott Witlin?A) Voice actors should have a pay raise if they prove to be top craftsmen.B) Changing the pay system would cause the industry more problems.C) Voice actors are mere craftsmen, not professional performers.D) Paying voice actors on an hourly basis is in line with the law.Passage TwoQuestions 51 to 55 are based on the following passage.Officials at the White House announced a new space policy focused on mana ging the increasing number of satellites that companies and governments are launching into space. Space Policy Directive-3 lays out general guidelines for t he United States to mitigate (缓解) the effects of space debris and track and manage traffic in space.This policy sets the stage for the Department of Commerce to take over the management of traffic in space. The department will make sure that newly la unched satellites don't use radio frequencies that would interfere with existin g satellites, and schedule when such new satellites can be launched. This only applies to American space activities, but the hope is that it will help standar dize a set of norms in the dawning commercial spaceflight industry through out the world.Space, especially the space directly around our planet, is getting more crowd ed as more governments and companies launch satellites. One impetus for th e policy is that companies are already starting to build massive constellation s (星座),comprising hundreds or thousands of satellites with many moving parts amon g them. With so much stuff in space, and a limited area around our planet, t he government wants to reduce the chances of a collision. Two or more satel lites slamming into each other could create many more out-of-control bits that would pose even more hazards to the growing collection of satellites in sp ace.And it's not like this hasn't happened before. In 2009 an old Russian craft sla mmed into a communications satellite, creating a cloud of hundreds of pieces of debris and putting other hardware at risk. Journalist Sarah Scoles reports t hat NASA currently tracks about 24,000 objects in space, and in 2016 the Air Force had to issue 3 ,995 ,874 warnings to satellite owners alerting them to a potential nearby threat from another satellite or bit of debris.That's why this new policy also includes directions to update the current U. S. Government Orbital Debris Mitigation Standard Practices, which already re quire any entity that launches a satellite or spacecraft to vigorously analyz e the likelihood that any of their actions , from an unexpected failure or no rmal operations, will create more space debris. It includes accounting for any piece of debris they plan to release over 5mm that might stay in orbit for 25 years or more. It might seem surprising to think about an item staying in spa ce for that long, but the oldest satellite still in orbit- Vanguard 1- turned 60 in 2018.Agencies and companies throughout the world are working on developing tech nology that would dispose of or capture space debris before it causes seriou s damage. But for now, the U. S. government is more focused on preventing new debris from forming than taking the trash out of orbit.51. What is the purpose of the new U. S. space policy?A) To lay out general guidelines for space exploration.B) To encourage companies to join in space programs.C) To make the best use of satellites in space.D) To improve traffic conditions in space.52. What is the Department of Commerce expected to do under the new polic y?A) Reduce debris in space.B) Monitor satellite operations.C) Regulate the launching of new satellites.D) Update satellite communications technology.53. What does the U. S. government hope to do with the new space policy?A) Set international standards for the space fight industry.B) Monopolize space industry by developing a set of norms.C) Facilitate commercial space flights throughout the world.D) Promote international collaboration in space exploration.54. What is a space vehicle launching entity required to do according to the current U. S. Government Orbital Debris Mitigation Standard Practices?A) Give an estimate of how long its debris will stay in space.B) Account for the debris it has released into space at any time.C) Provide a detailed plan for managing the space debris it creates.D) Make a thorough analysis of any possible addition to space debris.55. What are space agencies and companies aiming to do at present?A) Recycle used space vehicles before they turn into debris.B) Develop technology to address the space debris problem.C) Limit the amount of debris entering space.D) Cooperate closely to retrieve space debris.Part IV Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage f rom Chinese into English.

cognitive researchers likePiaget,adulthood meant the beginning of an_27_.Piaget argued that once adolescents enter the world of work,their newly acquired ability to form hypotheses allows them to create representations that are too ideal.The_28_of such ideals,without the tempering of the reality of a job or profession,rapidly leads adolescents to become _29_ of the non-idealistic world and to press for reform in a characteristically adolescent way.Piaget said:“True adaptation to society comes_30_when the adolescent reformer attempts to put his ideas to work.”Of course,youthful idealism is often courageous,and no one likes to give up dreams.Perhaps,taken_31_out of context,Piaget’s statement seems harsh.What he was_32_,however,is the way reality can modify idealistic views.Some people refer to such modification as maturity.Piaget argued that attaining and accepting a vocation is one of the best ways to modify idealized views and to mature.As careers and vocations become less available during times of _33_,adolescents may be especially hard hit.Such difficult economic times may leave many adolescents_34_about their roles in society.For this reason,community interventions

this section,you are going to read a passage with ten statements attached to it.Each statement contains information given in one of the paragraphs.Identify the paragraph from which the information is derived.You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking the corresponding letter on Answer Sheet 2.Can societies be rich and green?[A]“If our economies are to flourish,if global poverty is to be eliminated and if the well-being of the world’s people enhanced—not just in this generation but in succeeding generations—we must make sure we take care of the natural environment and resources on which our economic activity depends.”That statement comes not,as you might imagine,from a stereotypicaltree-hugging,save-the-world greenie(环保主义者),but from Gordon Brown,a politician with a reputation for rigour,thoroughness and above all,caution.[B]A surprising thing for the man who runs one of the world’s most powerful economies to say?Perhaps;though in the run-up to the five-year review of the Millennium(千年的)Goals,he is far from alone.The roots of his speech,given in March at the roundtable meeting of environment and energy ministers from the G20 group of nations,stretch back to 1972,and the United Nations Conference on the Human Environment in Stockholm.[C]“The protection and improvement of the human environment is a major issue which affects the well-being of peoples and economic development throughout the world,”read the final declaration from this gathering,the first of a sequence which would lead to the Rio de Janeiro Earth Summit in 1992 and the World Development Summit in Johannesburg three years ago.[D]Hunt through the reports prepared by UN agencies and development groups —many for conferences such as this year’s Millennium Goals review—and you will find that the linkage between environmental protection and economic progress is a common thread.[E]Managing ecosystems sustainably is more profitable than exploitingthem,according to the Millennium Ecosystem Assessment.But finding hard evidence to support the thesis is not so easy.Thoughts turn first to some sort of global statistic,some indicator which would rate the wealth of nations in both economic and environmental terms and show a relationship between the two.[F]If such an indicator exists,it is well hidden.And on reflection,this is not surprising;the single word“environment”has so many dimensions,and there are so many other factors affecting wealth—such as the oil deposits—that teasing out a simple economy-environment relationship would be almost impossible.[G]The Millennium Ecosystem Assessment,a vast four-year global study which reported its initial conclusions earlier this year,found reasons to believe that managing ecosystems sustainably—working with nature rather than against it—might be less profitable in the short term,but certainly brings long-term rewards.[H]And the World Resources Institute(WRI)in its World Resources 2005report,issued at the end of August,produced several such examples from Africa and Asia;it also demonstrated that environmental degradation affects the poor more than the rich,as poorer people derive a much higher proportion of their income directly from the natural resources around them.[I]But there are also many examples of growing wealth by trashing the environment,in rich and poor parts of the world alike,whether through unregulated mineral extraction,drastic water use for agriculture,slash-and-burn farming,orfossil-fuel-guzzling(大量消耗)transport.Of course,such growth may not persist in the long term—which is what Mr.Brown and the Stockholm declaration were both attempting to point out.Perhaps the best example of boom growth and bust decline is the Grand Banks fishery.For almost five centuries a very large supply of cod(鳕鱼)provided abundant raw material for an industry which at its peak employed about 40,000 people,sustaining entire communities in Newfoundland.Then,abruptly,the cod population collapsed.There were no longer enough fish in the sea for the stock to maintain itself,let alone an industry.More than a decade later,there was no sign of the ecosystem re-building itself.It had,apparently,been fished out of existence;and the once mighty Newfoundland fleet now gropes about frantically for crab on the sea floor.[J]There is a view that modern humans are inevitably sowing the seed of a global Grand Banks-style disaster.The idea is that we are taking more out of what you might call the planet’s environmental bank balance than it can sustain;we are living beyond our ecological means.One recent study attempted to calculate the extent of this“ecological overshoot of the human economy”,and found that we are using 1.2 Earth’s-worth of environmental goods and services—the implication being that at some point the debt will be called in,and all those services—the things which the planet does for us for free—will grind to a halt.[K]Whether this is right,and if so where and when the ecological axe will fall,is hard to determine with any precision—which is why governments and financial institutions are only beginning to bring such risks into their economic calculations.It is also the reason why development agencies are not united in their view of environmental issues;while some,like the WRI,maintain that environmental progress needs to go hand-in-hand with economic development,others argue that the priority is to build a thriving economy,and then use the wealth created to tackle environmental degradation.[L]This view assumes that rich societies will invest in environmental care.But is this right?Do things get better or worse as we get richer? Here the Stockholmdeclaration is ambiguous.“In the developing countries,”it says,“most of the environmental problems are caused by under-development.”So it is saying that economic development should make for a cleaner world?Not necessarily;“In the industralised countries,environmental problems are generally related to industrialisation and technological development,”it continues.In other words,poor and rich both over-exploit the natural world,but for different reasons.It’s simply not true that economic growth will surely make our world cleaner.[M]Clearly,richer societies are able to provide environmental improvements which lie well beyond the reach of poorer communities.Citizens of wealthy nations demand national parks,clean rivers,clean air and poison-free food.Theyalso,however,use far more natural resources-fuel,water(all those baths and golf courses)and building materials.[N]A case can be made that rich nations export environmental problems,the most graphic example being climate change.As a country’s wealth grows,so do its greenhouse gas emissions.The figures available will not be completelyaccurate.Measuring emissions is not a precise science, particularly when it comes to issues surrounding land use;not all nations have re-leased up-to-date data,and in any case,emissions from some sectors such as aviation are not included in national statistics.But the data is exact enough for a clear trend to be easily discernible.As countries become richer,they produce more greenhouse gases;and the impact of those gases will fall primarily in poor parts of the world.[O]Wealth is not,of course,the only factor involved.The average Norwegian is better off than the average US citizen,but contributes about half as much to climate change.But could Norway keep its standard of living and yet cut its emissions to Moroccan or even Ethiopian levels?That question,repeated across a dozen environmental issues and across our diverse planet,is what will ultimately determine whether the human race is living beyond its ecological means as it pursues economic revival.36.Examples show that both rich and poor countries exploited the environmentfor economic progress.37.Environmental protection and improvement benefit people all over the world.38.It is not necessarily true that economic growth will make our world cleaner.39.The common theme of the UN reports is the relation between environmental protection and economic growth.40.Development agencies disagree regarding how to tackle environment issues while ensuring economic progress.41.It is difficult to find solid evidence to prove environmental friendliness generates more profits than exploiting the natural environment.42.Sustainable management of ecosystems will prove rewarding in the long run.43.A politician noted for being cautious asserts that sustainable human development depends on the natural environment.44.Poor countries will have to bear the cost for rich nations’economic development.45.One recent study warns us of the danger of the exhaustion of natural resources on Earth.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Interactive television advertising, which allows viewers to use their remote controls to click on advertisements, has been pushed for years. Nearly a decade ago it was predicted that viewers of “Friends”, a popular situation comedy, would soon be able to purchase a sweater like Jennifer Aniston’s with a few taps on their remotecontrol.“It’s been the year of interactive television advertising for the last ten or twelve years,”says Colin Dixon of a digital-media consultancy.So the news that Cablevision, and American cable company, was rolling out interactive advertisements to all its customers on October 6th was greeted with some skepticism. During commercials, an overlay will appear at the bottom of the screen, prompting viewers to press a button to request a free sample or order a catalogue. Cablevision hopes to allow customers to buy things with their remote controls early next year.Television advertising could do with a boost. Spending fell by 10% in the first half of the year. The popularization of digital video recorders has caused advertisers to worry that their commercials will be skipped. Some are turning to the Internet, which is cheaper and offers concrete measurements like click-through rates—especially important at a time when marketing budgets are tight. With the launch of interactive advertising,“many of the dollars that went to the Internet will come back to the TV,”says David Kline of Cablevision. Or so the industry hopes.In theory, interactive advertising can engage viewers in a way that 30-second spots do not. Unilever recently ran an interactive campaign for its Axe deodorant(除臭剂),which kept viewers engaged for more than three minutes on average.The amount spent on interactive advertising on television is still small. Magna, an advertising agency, reckons it will be worth about $138 million this year. That falls far short of the billions of dollars people once expected it to generate. But DirecTV, Comcast and Time Warner Cable have all invested in it. A new effort led by Canoe Ventures, a coalition of leading cable providers, aims to make interactive advertising available across America later this year. BrightLine iTV, Which designs and sells interactive ads, says interest has surged: it expects its revenues almost to triple this year. BSkyB, Britain’s biggest satellite-television service, already provides 9 million customers with interactive ads.Yet there are doubts whether people watching television, a“lean back”medium, crave interaction. Click-through rates have been high so far(around 3-4%, compared with less than 0.3% online), but that may be a result of the novelty. Interactive adsand viewers might not go well together.46.What does Colin Dixon mean by saying“It’s been the year of interactive television advertising for the last ten or twelve years”(Lines 4-5, Para.1)?A)Interactive television advertising will become popular in 10-12 years.B)Interactive television advertising has been under debate for the last decade or so.C)Interactive television advertising is successful when incorporated into situation comedies.D)Interactive television advertising has not achieved the anticipated results.47.What is the public’s response to Cablevision’s planned interactive TV advertising program?A)Pretty positive.B)Totally indifferent.C)Somewhat doubtful.D)Rather critical.48.What is the impact of the wide use of digital video recorders on TV advertising?A)It has made TV advertising easily accessible to viewers.B)It helps advertisers to measure the click-through rates.C)It has placed TV advertising at a great disadvantage.D)It enables viewers to check the sales items with ease.49.What do we learn about Unilever’s interactive campaign?A)It proves the advantage of TV advertising.B)It has done well in engaging the viewers.C)It helps attract investments in the company.D)it has boosted the TV advertising industry.50.How does the author view the hitherto high click-through rates?A)They may be due to the novel way of advertising.B)They signify the popularity of interactive advertising.C)They point to the growing curiosity ofTV viewers.D)They indicate the future direction of media reform.Passage TwoQuestions 51 to 55 are based on the following passage.What can be done about mass unemployment? All the wise heads agree: there’re no quick or easy answers. There’s work to be done, but workers aren’t ready to do it—they’re in the wrong places, or they have the wrong skills, Our problems are “structural,”and will take many years to solve.But don’t bother asking for evidence that justifies this bleak view. There isn’t any. On the contrary, all the facts suggest that high unemployment in America is the result of inadequate demand. saying that there’re no easy answers sounds wise. But it’s actually foolish: our unemployment crisis could be cured very quickly if we had the intellectual clarity and political will to act. In other words, structural unemployment is a fake problem, which mainly serves as an excuse for not pursing real solutions.The fact is job openings have plunged in every major sector, while the number of workers forced into part-time employment in almost all industries has soared. Unemployment has surged in every major occupational category. Only three states. With a combined population not much larger than that of Brooklyn, have unemployment rates below 5%. So the evidence contradicts the claim that we’re mainly suffering from structural unemployment. Why, then, has this claim become so popular?Part of the answer is that this is what always happens during periods of high unemployment—in part because experts and analysts believe that declaring the problem deeply rooted, with no easy answers, makes them sound serious.I’ve been looking at what self-proclaimed experts were saying about unemployment during the Great Depression; it was almost identical to what Very Serious People are saying now. Unemployment cannot be brought down rapidly,declared one 1935 analysis, because the workforce is“unadaptable and untrained. It cannot respond to the opportunities which industry may offer.”A few years later, a large defense buildup finally provided a fiscal stimulus adequate to the economy’s needs—and suddenly industry was eager to employ those“unadaptable and untrained”workers.But now, as then, powerful forces are ideologically opposed to the whole idea of government action on a sufficient scale to jump-start the economy. And that, fundamentally, is why claims that we face huge structural problems have been multiplying: they offer a reason to do nothing about the mass unemployment that is crippling out economy and our society.So what you need to know is that there’s no evidence whatsoever to back these claims. We aren’t suffering from a shortage of needed skills, We’re suffering from a lack of policy resolve. As I said, structural unemployment isn’t a real problem, it’s an excuse—a reason not to act on America’s problems at a time when action is desperately needed.51.What does the author think is the root cause of mass unemployment in America?A)Corporate mismanagement.B)Insufficient demand.C)Technological advances.D)Workers’slow adaptation.52.What does the author think of the experts’claim concerning unemployment?A)Self-evident.B)Thought-provoking.C)Irrational.D)Groundless.53.What does the author say helped bring down unemployment during the Great Depression?A)The booming defense industry.B)The wise heads’benefit package.C)Nationwide training of workers.D)Thorough restructuring of industries.54.What has caused claims of huge structural problems to multiply?A)Powerful opposition to government’s stimulus efforts.B)Very Serious People’s attempt to cripple the economy.C)Evidence gathered from many sectors of the industries.D)Economists’failure to detect the problems in time.55.What is the author’s purpose in writing the passage?A)To testify to the experts’analysis of America’s problems.B)To offer a feasible solution to the structural unemployment.C)To show the urgent need for the government to take action.D)To alert American workers to the urgency for adaptation.Part IV Translation (30minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.
