Now, as the pace of technological change continues to 42 , it has become increasingly possible to design computing systems that enhance the human experience, or now—in a growing number of cases—completely 43 with it. Watson is an effort by IBM researchers to advance a set of techniques used to process human language. It provides 44 evidence that computing systems will no longer be limited to responding to simple commands. Machines will increasingly be able to pick out jargon (行话) and even riddles. In attacking the problem of the 45 of human language, computer science is now closing in on what researchers refer to as the 'Paris Hilton problem' —the ability, for example, to determine whether an 46 is being made by someone who is trying to reserve a hotel in France, or 47 to pass time surfing the Internet. Traditionally, economists have argued that while new forms of automation may displace jobs in the short run, over longer periods of time economic growth and job creation have continued to 48 any job-killing technology. Over the past century and a half the 49 from being a largely agrarian (农业的) society to one in which less than 1 percent of the United States labor force is in agriculture is frequently cited as 50 of the economy's ability to reinvent itself. Rapid progress in natural language processing is beginning to 51 to a new wave of automation that promises to transform areas of the economy that have until now been untouched by technological change.

单选题 SECTION A MULTIPLE CHOICE QUESTIONS In this section there are four passages followed by nine multiple choicequestions. For each question, there are four suggested answers marked A, B, Cand D. Choose the one that you think is the best answer. Passage One Comedy's legendary Monty Python members-you know. 'I'm a lumberjack andI'm okay,' the Killer Rabbit, the Dead Parrot-were tired of seeing their legendarysketches pirated and fuzzily posted on You Tube, free to whoever wanted a quicklaugh. So they posted their own, higher-quality versions on YouTube-also free-but letfans know that complete DVD versions were available for purchase. Sales rose 23,000 percent. 'Free worked, and worked brilliantly…People are making lots of moneycharging nothing. Not nothing for everything, but nothing for enough that we haveessentially created a country-sized economy around the price of $0.00.' Anderson,48, the editor of Wired magazine, discussed the allure of zero with Jesse Kornbluth. In the 20th century 'free' meant giving away one thing to create demand foranother. Get a free cell phone, for example, by buying a monthly plan. What is 'free'now? Yes, 20th-century 'free' was about real objects made of atoms. Real costs were involved, so the consumer paid one way or another. In the 21th century, 'free' is digital bit with marginal costs. For all practical purposes, they really are free. In the digital economy, someone pays, but increasingly it's not you. Google and Wikipedia, for example, don't show up on your credit card. So how do you pay? Not with money, but with your time and attention. Some resources, of course, are scarce and getting scarcer; you pay for those. Digital goods and services, because they can be reproduced and distributed at almost no cost, are abundant. Once you've given content away on the Web, can you get people to pay? Absolutely. Use 'free' to get an audience, then segment your user base so you have a free version and a premium one. The Wall Street Journal created a clever hybrid-some free articles, some available only to paid subscribers. I get the sense that-when it comes to news, anyway-we'll soon have two classes of Internet users: 1 ) people who have money and will pay for quality reporting and analysis, and 2) people who are less well-off or care less about quality and will accept any information that's free. So the elite will be better informed, and others may get trashier media. I'm simply observing what happens in economics when marginal costs fall. In economic terms, 'free' is the law of gravity. I don't tell the apple to fall; it just falls. I don't tell water to flow downhill; it just does. In that way, it's simple: As costs approach zero, 'free' prevails. Passage Two Diamonds, sparkling under an African sun, have an attraction commensurate with their high price and beauty. For Anglo-American the opportunity to get their hands on some more has proved too much to resist. On November 4th the global mining giant announced that it would acquire the 40% of De Beers, a company that mines two-fifths of the world's diamonds, from the Oppenheimer family for $5.1 billion. This takes Anglo-American's stake in De Beers to 85%; the rest is owned by the government of Botswana, where the firm digs up its gems. The price looks right. Demand for diamonds has bounced back after the credit crisis in 2008 and the following recession in the rich world. More and more wealthy Indians and Brazilians seem keen to sport a 'rock' to show just how well they are doing. And the shrewd Oppenheimers do not seem to be getting out of the business because its future looks bleak. There is apparently no family member who wants to take on diamond mining. Nicky Oppenheimer, De Beers's chairman, foresaw the sale in February when he stood down from the board of Anglo-American. For Anglo-American it resolves the issue of its non-controlling stake in De Beers. Analysts have long reckoned it should either sell or try to increase its stake. In fact the firm might yet spin off De Beers with an IPO. The terms of the deal allow the Oppenheimers to pocket some more cash from a flotation or sale in the next couple of years, suggesting that such an outcome is not unlikely. It would also make sense. Anglo-American is a different beast to the global diversified mining giants that would count as its competitors. It stood apart from the wave of mining mega-mergers over the past decade or so-except as a potential target. The consolidation and the emergence of huge markets for the world's resources have propelled BHP Billiton, for instance, to become one of the world's biggest listed companies. Many would claim that Anglo-American has suffered as a result. Once one of the world's biggest miners, it now ranks alongside Xstrata, a company just ten years old, which in 2009 even attempted a nil-premium takeover of Anglo. It also has a significant portion of its assets in South Africa. And unlike its peers it has a large platinum business, as well as all the diamonds. Anglo-American's recent strategy has been to diversify out of South Africa, where the threat of nationalization, scarcely credible but a fear for investors none the less, hangs over it. Black-empowerment laws, a scarcity of water and electricity as well as an obstinate workforce make it a difficult place to operate. Botswana is far more accommodating, but it might also make sense to get out of diamonds: it is a business that is more about branding the rocks and less about the savvy capital deployment and logistical know-how that are the hallmarks of the mining business. If that is Anglo' eventual aim, then the deal looks like a smart move. Passage Three Younger Americans will have to take our word for it: there was a time, way back when Ronald Reagan was president, when your countrymen ordered coffee by simply asking for 'coffee'. Ordering a 'venti skinny chai latte' or a 'grande chocolate cookie crumble frappuccino' would have earned, at best, a blank stare. But that was before Howard Schultz took Starbucks from a single coffeehouse in downtown Seattle to a chain with more than 17,000 shops in 55 countries. The chain grew so quickly, and in some areas seemed so ubiquitous, that as early as 1998 a headline in The Onion, a satirical American newspaper, joked, 'New Starbucks Opens in Rest Room of Existing Starbucks'. After suffering through lean years in 2008 and 2009, the company is again going strong. In the 2011 financial year the company served 60m customers per week — more than ever. It also had its highest-ever earnings-per-share ($1.62) and global net revenue ($11.7 billion). Yet in 2011 Starbucks decided to do away with something important: it dropped the word 'Coffee' from its logo. While coffee remains as central to Starbucks' business and identity as hamburgers are to McDonald's, the company's recent American acquisitions have moved it beyond java. In November 2011 it acquired Evolution Fresh, a small California-based juice company, for $30m, giving the company a foothold in America's $1.6 billion high-end juice market. And in June 2012 Starbucks bought a bakery, Bay Bread, and its La Boulange-branded cafes, for $100m. Starbuck's customers 'have never been as satisfied with our food as our coffee,' explained Troy Alstead, Starbucks's chief financial officer. On November 14th Starbucks made it largest acquisition yet, buying Teavana, an Atlanta based tea retailer, for $620m. This is not the firm's first attempt into the tea market — its stores sell tea, of course, and it bought Tazo, a tea manufacturer and distributor, back in 1999 — but it is by far its boldest. When Starbucks bought Tazo it was simply a brand, but Teavana has some 300 shops, largely mall-based, throughout North America. Mr. Alstead hopes that scale will allow Starbucks 'to do for tea what we did for coffee'. This may seem, as they say at Starbucks, a tall order. Americans drink far more coffee than tea. In 2011 the average coffee consumption was 9.39 pounds per person, while tea was a paltry 0.9 pounds. Coffee has long been an essential part of American mornings. Tea has no comparably firm position, except for the tooth-shiveringly sweet iced tea served during meals in the South (85% of all tea consumed in America is iced). That said, since 1980 America's coffee consumption has fallen, and is forecast to fall further. Consumption of tea, on the other hand, has grown, and is forecast to keep growing-perhaps benefiting from the idea that it has health benefits that coffee lacks, perhaps driven partly by immigration from tea-drinking countries. The Tea Association of the USA put the value of the tea market in America at $8.2 billion in 2011, up from $1.8 billion just 20 years earlier, and forecasts that it will nearly double in value again by 2014. The sharpest growth will come from tea that is green-which also happens to be the color of money and the logo of Starbucks. Passage Four Late last year, Airbnb announced that it's going after the major hotel chains-which at first sounded kind of cute, like a precocious Little League pitcher saying he's going to strike out Miguel Cabrera. But when CEO Brian Chesky laid out his thinking for me in Airbnb's new, funky headquarters in San Francisco, I thought the investors who have pumped $326 million into the company might not be too dim. Airbnb is becoming much more than a way to spend $26 a night to sleep in London with five other people at The Imperial Fleapit. In fact, Airbnb is looking like a proof point of a trend that has been getting a lot of attention lately. Some refer to it as the DIY-for do it yourself-movement. Chesky uses the term 'decentralized production (分散式生产).' Marc Andreessen hit on the concept in a manifesto entitled 'Why Software Is Eating the World?' It all points to the same idea: Information technology is eroding the power of large-scale mass production. We're instead moving toward a world of massive numbers of small producers offering unique stuff-and of consumers who reject mass-produced stuff. The Internet, software, 3D printing, social networks, cloud computing and other technologies are making this economically feasible-in fact, desirable. The hotel industry-and the way Airbnb thinks about it-is an example of how that is playing out. There is a fundamental truth about big hotel chains that is only now being exposed in the Internet age: Hotel chains grew out of a lack of information. In the middle of last century, cars and highways made the world far more mobile. Many more people traveled to towns they didn't know, and they needed places to sleep. They had no way to know which hotel or boarding house might be nice or offer amenities they wanted. Travel guides, like Mobil's, popped up in the 1950s, but fdr the most part information remained scarce. Chains took advantage of that data deficit. If you knew a Holiday Inn in one town, you knew the Holiday Inn in the next town would be roughly the same. The brand's motto played off this: 'The best surprise is no surprise. ' The uniformity and comfort of a chain trumped the risk of an unknown, independent place. As chains got bigger, they could afford to widely advertise-a way to spread more information about the consistency of their hotels. Independents couldn't keep up. They had limited ways to get information to travelers. As long as this big information gap existed, chains grew and independents struggled. The gap drove chains to offer uniform accommodations at scale-and we got today's hospitality industry, dominated by the likes of Hilton, Marriott and Starwood. Chesky got to thinking about this when his late grandfather told him Airbnb reminded him of his childhood, when his family would arrive in towns and stay at boarding houses. Chesky thought: If the Internet was around back then, would hotel chains as we know them have been created? 'And the answer is absolutely not,' Chesky says. 'I'm not saying there wouldn't be hotels, but they wouldn't look like they do today.'
