单选题When it comes to battles between Apple and Samsung, the conflict is often explored in terms of patents or smartphone sales. But what about their innovation styles? Management consulting firm Booz & Company released its eighth annual Global Innovation 1000 Study in the last week of October. Among the study"s key findings were that research and development spending had reached an "all-time high, " increasing by 9.6 percent in 2011 for a total $603 billion, and that Amazon edged out Facebook to join the study"s top 10 "most innovative" companies. The top 10 list was compiled based on answers from survey respondents who were asked which companies they found to be the most innovative. Apple, Google and 3M took the top three slots with Samsung, General Electric, Microsoft, Toyota, Procter & Gamble, IBM and, finally, Amazon rounding out the rest of the list. The last of three key findings were that roughly half of the corporations surveyed rated their effectiveness when it comes to getting products to market as "average" or "marginally effective. " That fact was drilled home by the survey"s list of top R&D spenders. Toyota topped the Research & Development(R&D)spenders list, coming in seventh among the most innovative companies. Apple and Google were not listed among the top 20 R&D spenders, even as they were named one and two, respectively, among the 10 most innovative. Samsung, meanwhile, was ranked the fourth most innovative and the sixth highest of the R&D spenders, rising from seventh place the year before. " It"s not how much money you spend, but how effectively you spend it to make you innovative, " said Booz & Company Partner John Loehr during a phone interview. Loehr is the global leader of the firm"s innovation practice, specializing in automotive, industrial and aerospace companies. " They"re both phenomenally successful, but they both have different innovation models, " said Loehr of Apple and Samsung, going on to describe Apple as a " prototypical example of what we call a " need seeker" " —or a company that identifies un-met needs in the market and moves to satisfy them. Samsung, on the other hand, is a "market reader, " said Loehr. The term "fast follower, " he continued, has often been used to describe Samsung, but Loehr maintains the term gives the company "short shrift. " "They"re waiting for something to be established in the market, and when it really takes off, " said Loehr, "they go after it and go after it aggressively. " The strategy has proven advantages, said Loehr, citing Samsung"s strides in the television market. "Successful market readers tend to find technology alternatives, " said Loehr. Sometimes that path can be found in the lab, and other times in the courts. "That"s part of the capability as a market reader, " he said.

单选题Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty. That compulsion has resulted in robotics—the science of conferring various human capabilities on machines. And ff scientists have yet to create the mechanical version of science fiction, they have begun to come close. As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by tireless robot-drivers. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy—far greater precision than highly skilled physicians can achieve with their hands alone. But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves—goals that pose a real challenge. "While we know how to tell a robot to handle a specific error," says Dave Lavery, manager of a robotics program at NASA, "we can't yet give a robot enough 'common sense' to reliably interact with a dynamic world." Indeed the quest for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor circuits and microprocessors might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries. What they found, in attempting to model thought, is that the human brain's roughly one hundred billion nerve cells are much more talented—and human perception far more complicated—than previously imagined. They have built robots that can recognize the error of a machine panel by a fraction of a millimeter in a controlled factory environment. But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd. The most advanced computer systems on the earth can't approach that kind of ability, and neuroscientists still don't know quite how we do it.

单选题The American economic system is organized around a basically private-enterprise, market oriented economy in which consumers largely determine what shall be produced by spending their money in the marketplace for those goods and services that they want most. Private businessmen, striving to make their profits, produce these goods and services in competition with other businessmen: and the profit motive, operating under competitive pressures, largely determines how these goods and services are produced. Thus, in the American economic system it is the demand of individual consumers, coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes, that together determine what shall be produced and how resources are used to produce it. An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers. In the American economy, this mechanism is provided by a price system, a process in which prices rise and fall in response to relative demands of consumers and supplies offered by seller-producers. If the product is in short supply relative to the demand, the price will be a bit up and some consumers will be eliminated from the market. If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to increase the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product. Thus, price is the regulating mechanism in the American economic system. The important factor in a private-oriented economy is that individuals are allowed to own productive resources (private property), and they are permitted to hire labor, gain control over natural resources, and produce goods and services for sale at a profit. In the American economy, the concept of private property embraces not only the ownership of productive resources but also certain rights, including the right to determine the price of a product or to make a free contract with another private individual.

单选题{{B}}Questions 11-15 are based on the following passage:{{/B}} Real policemen hardly recognize any resemblance(类同之处)between their lives and what they see on TV—if they ever get home in time. There are similarities, of course, but the cops (警官) don't think much of them. The first difference is that a policeman's real life revolves round the law. Most of his training is in criminal law. He has to know exactly what actions are crimes and what evidence can be used to prove them in court. He has to know nearly as much law as a professional lawyer, and what is more, he has to apply it on his feet, in the dark and rain, running down an alley after someone he wants to talk to. Little of his time is spent in chatting to scanty-clad ( 穿衣不多的 ) ladies or in dramatic confrontations with desperate criminals. He will spend most of his working life typing millions of words on thousands of forms about hundreds of sad, unimportant people who are guilt or not—of stupid, petty crimes.
