单选题 Passage 3 What do consumers really want? That's a question market researchers would love to answer. But since people don't always say what they think, marketers would need direct access to consumers' thoughts to get the truth. Now, in a way, that is possible. At the "Mind of the Market" laboratory at Harvard Business School, researchers are looking inside shoppers' skulls to develop more effective advertisements and marketing pitches. Using imaging techniques that measure blood flow to various parts of the brain, the Harvard team hopes to predict how consumers will react to particular products and to discover the most effective ways to present information. Stephen Kosslyn, a professor of psychology at Harvard, and business school professor Gerald Zaltman, oversee the lab. "The goal is not to manipulate people's preferences," says Kosslyn, "just to speak to their actual desires. "The group's findings, though still preliminary, could radically change how firms develop and market new products. The Harvard group use position emission topography (PET) scans to monitor the brain activity. These PET scans, along with other non-invasive imaging techniques; enable researchers to see which parts of the brain are active during specific tasks (such as remembering a word). Correlations have been found between blood flow to specific areas and future behavior. Because of this, Harvard researchers believe the scans can also predict future purchasing patterns. According to an unpublished paper the group produced, "It is possible to use these techniques to predict not only whether people will remember and have specific emotional reactions to certain materials, but also whether they will be inclined to want those materials months later. " The Harvard group is now moving into the next stage of experiments. They will explore how people remember advertisements as part of an effort to predict how they will react to a product after having seen an ad. The researchers believe that once key areas of the brain are identified, scans on about two dozen volunteers will be enough to draw conclusions about the reactions of specific segments of the population. Large corporations — including Coca Cola, Eastman Kodak, General Motors, and Hallmark — have already signed up to fund further investigations. For their financial support, these firms gain access to the experiments, but cannot control them. If Kosslyn and Zaltman and their team really can read the mind of the market, then consumers may find it even harder to get those advertising jingles out of their heads.

Our present concern is with how easily and to what extent this【C2】______can be modified. The question is no mere academic one. The ease with which people can change from working in the day to working at night is a【C3】______of growing importance in industry where automation【C4】______round-the-clock working of machines. It normally【C5】______form five days to one week for a person to adapt to a【C6】______routine of sleep and wakefulness, sleeping during the day and working at night.【C7】______, it is often the case in industry that shifts are changed every week. This means that no sooner has he got used to one routine【C8】______he has to change to another,【C9】______much of his time is spent neither working nor sleeping very【C10】______.

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 if 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 robo-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 Earth can't approach that kind of ability, and neuroscientists still don't know quite how we do it.
