Mark your answers on the ANSWER SHEET.（40 points）Text 1Among the annoying challenges facing the middle class is one that will probably go unmentioned in the next presidential campaign: What happens when the robots come for their jobs?Dont dismiss that possibility entirel

11、y. About half of U.S. jobs are at high risk of being automated, according to a University of Oxford study, with the middle class disproportionately squeezed. Lower-income jobs like gardening or day care dont appeal to robots. But many middle-class occupations-trucking, financial advice, software eng

12、ineering have aroused their interest, or soon will. The rich own the robots, so they will be fine.This isnt to be alarmist. Optimists point out that technological upheaval has benefited workers in the past. The Industrial Revolution didnt go so well for Luddites whose jobs were displaced by mechaniz

13、ed looms, but it eventually raised living standards and created more jobs than it destroyed. Likewise, automation should eventually boost productivity, stimulate demand by driving down prices, and free workers from hard, boring work. But in the medium term, middle-class workers may need a lot of hel

14、p adjusting.The first step, as Erik Brynjolfsson and Andrew McAfee argue in The Second Machine Age, should be rethinking education and job training. Curriculums from grammar school to college- should evolve to focus less on memorizing facts and more on creativity and complex communication. Vocationa

15、l schools should do a better job of fostering problem-solving skills and helping students work alongside robots. Online education can supplement the traditional kind. It could make extra training and instruction affordable. Professionals trying to acquire new skills will be able to do so without goi

16、ng into debt.The challenge of coping with automation underlines the need for the U.S. to revive its fading business dynamism: Starting new companies must be made easier. In previous eras of drastic technological change, entrepreneurs smoothed the transition by dreaming up ways to combine labor and m

17、achines. The best uses of 3D printers and virtual reality havent been invented yet. The U.S. needs the new companies that will invent them.Finally, because automation threatens to widen the gap between capital income and labor income, taxes and the safety net will have to be rethought. Taxes on low-

18、wage labor need to be cut, and wage subsidies such as the earned income tax credit should be expanded: This would boost incomes, encourage work, reward companies for job creation, and reduce inequality.Technology will improve society in ways big and small over the next few years, yet this will be li

19、ttle comfort to those who find their lives and careers upended by automation. Destroying the machines that are coming for our jobs would be nuts.

23、icans disapprove of President Trumps use of Twitter. The implication is that Millennials prefer news from the White House to be filtered through other source, Not a presidents social media platform.Most Americans rely on social media to check daily headlines. Yet as distrust has risen toward all med

24、ia, people may be starting to beef up their media literacy skills. Such a trend is badly needed. During the 2016 presidential campaign, nearly a quarter of web content shared by Twitter users in the politically critical state of Michigan was fake news, according to the University of Oxford. And a su

25、rvey conducted for Buzz Feed News found 44 percent of Facebook users rarely or never trust news from the media giant.Young people who are digital natives are indeed becoming more skillful at separating fact from fiction in cyberspace. A Knight Foundation focus-group survey of young people between ag

26、es 14and24 found they use “distributed trust” to verify stories. They cross-check sources and prefer news from different perspectivesespecially those that are open about any bias. “Many young people assume a great deal of personal responsibility for educating themselves and actively seeking out oppo

27、sing viewpoints,” the survey concluded.Such active research can have another effect. A 2014 survey conducted in Australia, Britain, and the United States by the University of Wisconsin-Madison found that young peoples reliance on social media led to greater political engagement.Social media allows u

28、sers to experience news events more intimately and immediately while also permitting them to re-share news as a projection of their values and interests. This forces users to be more conscious of their role in passing along information. A survey by Barna research group found the top reason given by

29、Americans for the fake news phenomenon is “reader error,” more so than made-up stories or factual mistakes in reporting. About a third say the problem of fake news lies in “misinterpretation or exaggeration of actual news” via social mediaIn other words, the choice to share news on social media may

30、be the heart of the issue. “This indicates there is a real personal responsibility in counteracting this problem,” says Roxanne Stone, editor in chief at Barna Group.So when young people are critical of an over-tweeting president, they reveal a mental discipline in thinking skills and in their choic

31、es on when to share on social media.26.【题干】According to the Paragraphs 1 and 2, many young Americans cast doubts on【选项】Athe justification of the news-filtering practice.Bpeoples preference for social media platforms.Cthe administrations ability to handle information.Dsocial media was a reliable sour

35、ealth Service (NHS) and DeepMind must start by acknowledging that both sides mean well. DeepMind is one of the leading artificial intelligence (AI) companies in the world. The potential of this work applied to healthcare is very great, but it could also lead to further concentration of power in the

36、tech giants. It Is against that background that the information commissioner, Elizabeth Denham, has issued her damning verdict against the Royal Free hospital trust under the NHS, which handed over to DeepMind the records of 1.6 million patients In 2015 on the basis of a vague agreement which took f

37、ar too little account of the patients rights and their expectations of privacy.DeepMind has almost apologized. The NHS trust has mended its ways. Further arrangements- and there may be many-between the NHS and DeepMind will be carefully scrutinised to ensure that all necessary permissions have been

38、asked of patients and all unnecessary data has been cleanedThere are lessons about informed patient consent to learn. But privacy is not the only angle in this case and not even the most important. Ms. Denham chose to concentrate the blame on the NHS trust, since under existing law it “controlled” t

39、he data and DeepMind merely “processed it. But this distinction misses the point that it is processing and aggregation, not the mere possession of bits, that gives the data value.The great question is who should benefit from the analysis of all the data that our lives now generate. Privacy law build

40、s on the concept of damage to an individual from identifiable knowledge about them. That misses the way the surveillance economy works. The data of an individual there gains its value only when it is compared with the data of countless millions more.The use of privacy law to curb the tech giants in

41、this instance feels slightly maladapted. This practice does not address the real worry. It is not enough to say that the algorithms DeepMind develops will benefit patients and save lives. What matters is that they will belong to a private monopoly which developed them using public resources. If soft

42、ware promises to save lives on the scale that dugs now can, big data may be expected to behave as a big pharm has done. We are still at the beginning of this revolution and small choices now may turn out to have gigantic consequences later. A long struggle will be needed to avoid a future of digital

43、 feudalism. Ms. Denhams report is a welcome start.31.【题干】Wha is true of the agreement between the NHS and DeepMind ?【选项】AIt caused conflicts among tech giants.BIt failed to pay due attention to patients rights.CIt fell short of the latters expectationsDIt put both sides into a dangerous situation.32

It reported a net loss of $5.6 billion for fiscal 2016, the 10th straight year its expens

47、es have exceeded revenue. Meanwhile, it has more than $120 billion in unfunded liabilities, mostly for employee health and retirement costs. There are many bankruptcies. Fundamentally, the USPS is in a historic squeeze between technological change that has permanently decreased demand for its bread-and-butter product, first-class mail, and a regulatory structure that denies management the flexibility to adjust its operations to the new realityAnd interest groups ranging from postal unions
