单选题{{B}}TEXT C{{/B}} The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software or by altering the architecture but that too will happen. I think it certain that in decades, not centuries, machines of silicon will arise first to rival and then exceed their human ancestors. Once they exceed us, they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended {{U}}carbon's{{/U}} long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe. As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.

单选题It is a curious paradox that we think of the physical sciences as "hard", the social sciences as "soft", and the biological sciences as somewhere in between. This is interpreted to mean that our knowledge of physical system is more certain than our knowledge of biological systems, and these in turn are more certain than our knowledge of social systems. In terms of our capacity of sample the relevant universes, however, and the probability that our images of these universes are at least approximately correct, one suspects that a reverse order is more reasonable. We are able to sample earth's social systems with some degree of confidence that we have a reasonable sample of the total universe being investigated. Our knowledge of social systems, therefore, while it is in many ways extremely inaccurate, is not likely to be seriously overturned by new discoveries. Even the folk knowledge in social systems on which ordinary life is based in earning, spending, organizing, marrying, taking part in political activities, fighting and so on, is not very dissimilar from the more sophisticated images of the social system derived form the social sciences, even though it is built upon the very imperfect samples of personal experience. In contrast, our image of the astronomical universe, or even if earth's geological history, can easily be subject to revolutionary changes as new data come in and new theories are worked out. If we define the "security" of our image of various parts of the total system as the probability of their suffering significant changes, then we would reverse the order for hardness and as the most secure, the physical sciences as the least secure, and again the biological sciences as somewhere in between. Our image of the astronomical universe is the least secure of all simply because we observe such a fantastically small sample of it and its record-keeping is trivial records of biological systems. Records of the astronomical universe, despite the fact that we learnt things as they were long age, are limited in the extreme. Even in regard to such a close neighbor as the moon, which we have actually visited, theories about its origin and history are extremely different, contradictory, and hard to choose among. Our knowledge of physical evolution is incomplete and insecure.

Mark your answers on your ANSWER SHEET.{{B}}TEXT A{{/B}} Come September, the campuses of America will be swarming not just with returning undergraduates, but also with employers set on signing up the most able 10% of them. "We are seeing a far more competitive market for talent," says Steve Canale, a recruitment manager at General Electric (GE). Students who recently could have expected two or three offers in their final year are now getting as many as five. To gain a competitive edge, firms are arriving ever earlier on campus with their recruitment caravans. They also start to look at (and select) summer interns more as potential full-time empl6yees than as mere seasonal extra hands: 60% of GE's graduate recruits in America this year, for instance, will come from its crop of more than 2,000 interns. Many interns will have employment contracts in their pockets before they even return for their final year of study. Firms are working harder to polish their image in the eyes of undergraduates. Some have staff who do little but tour campuses throughout the year, keeping the firm's name in front of both faculty and students, and promoting their "employer brand". GE focuses on 38 universities where it actively promotes itself as an employer. Pricewaterhousecoopers (PWC), an accounting firm, targets 200 universalities and gives a partner responsibility for each. PWC says that each of its partners spends up to 200 hours a year" building relationships on campus". That particular investment seems to have paid off. Each year Universum, an employer-branding consultant, asks some 30,000 American students to name their ideal employer. In this year's survey, published recently, PWC came second (up from 4th in 2004), topped only by BWM. Yet the German carmaker, which knocked Microsoft off the top spot, steers clear of campuses, relying for its popularity, says Universum, on the "coolness" of its products. Students, it seems, are heavily influenced in their choice of ideal employer by their perception of that employer's products and services. Soaring up this year's list were Apple Computer (from 41st to 13th) and the Federal Bureau of Investment (from 138th to 10th). The success of Apple's cool iPod has had a powerful effect in the firm's ability to recruit top undergraduates. Likewise, the positive portrayal of the FBI in some recent films and TV shows has allegedly helped with recruitment. The accounting firms say that the fall of Enron and Arthur Andersen has done their recruitment no harm: instead, they claim, it has made students realize that accounting is not mere number crunching, but also involves moral judgments. The "Big Four" accounting firms are all among this year's top 15 ideal employers. Undergraduates now do much of their research into future employments online. There seems to be a close correlation between their choice of ideal employer and their choice of most impressive website--where PWC, Microsoft and Ernst & Young win gold, silver and bronze respectively. Even so, some famous firms think they still appreciate the personal touch, and are sending their most senior executives to campuses to meet students and to give speeches. "The top attracts top," says, Claudia Tattanelli, boss of Universum in America. Jeffrey Immelt, GE's chief executive, is a keen on-campus speaker and has visited six leading universities in the past year. In the process, he may have shaken hands with one of his successors.
