单选题Text 3 In general, our society is becoming one of giant enterprises directed by a bureaucratic management in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, well-ventilated factories and piped music, and by psychologists and "human-relations" experts; yet all this oiling does not alter the fact that man has become powerless, that he does not wholeheartedly participate in his work and that he is bored with it. In fact, the blue and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management. The worker and employee are anxious, not only because they might find themselves out of a job; they are anxious also because they are unable to acquire any real satisfaction or interest in life. They live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings. Those higher up on the social ladder are no less anxious. Their lives are no less empty than those of their subordinates. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the right mixture of submissiveness and independence. From that moment on they are tested again and again—by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one's fellow-competitor creates constant anxiety and stress, the very causes of unhappiness and illness. Am I suggesting that we should return to the preindustrial mode of production or to nineteenth century "free enterprise" capitalism? Certainly not. Problems are never solved by returning to a stage which one has already outgrown. I suggest transforming our social system for a bureaucratically managed industrialism in which maximal production and consumption are ends in themselves into a humanist industrialism in which man and full development of his potentialities—those of love and of reason—are the aims of all social arrangements. Production and consumption should serve only as means to this end, and should be prevented from ruling man.

单选题Passage Three When it comes to the economy, pessimism is in and good old American optimism is out. From the headlines in the newspapers to the coffee shop chatter, it seems that there is little good to say about the economy. Bad enough that the news about Iraq, winter storms and the escalation of terror alerts continue to keep people on edge. Reports of state budget deficits and threats of major cutbacks in services such as education, health care and police also make people nervous. The latest USA TODAY/CNN/Gallup Poll reflects the new pessimism. Asked early this past week how they would rate economic conditions in the country today, just one in three- 34%- said they consider it good. That's down 10 percentage points from December, when 44% rated the economy good and 20 points lower than September when 54% said they thought economic conditions were good. Moreover, when asked to look ahead a year from now, those people willing to say things will get better are also dwindling in numbers. A thin majority of 55% said they expected economic conditions to be better by this time next year. Not bad on the surface. But looking back just two months to December, 65%— or two of three— believed that things would improve in a year. And going back six months to September, 71% expressed optimism for economic improvement. So the seeds of discontent are out there and they could set off a political firestorm for President Bush if economic conditions don't start getting better soon. Or more importantly, if the American people don't start feeling better soon. Regardless of what the statistics say about how good the economy might be getting, the American people have to feel it. And often, feelings lag behind numbers. Indeed, most people believe that the economy is in recession. Statistically it is not. Case in point: On Friday, the U.S. Commerce Department reported that the economy grew at a 1.4% rate in the final quarter of last year — twice as fast as the government first estimated. Major factors in the upward revision in the gross domestic product were stronger investment by businesses in building up stockpiles of unsold goods and a slight boost to consumer spending, the main force keeping the economy going. But while that report is interesting, and perhaps a source of hope that things aren't as bad as they seem, more tangible examples of economic improvement are needed — solid gains in the stock market, rehiring by plants that have been laying off workers, new business expansion. The USA TODAY poll further shows that nervousness about Iraq and a still-sluggish economy are taking a political toll on Bush: His job approval rating is 57%, his lowest since before the Sept. 11 terrorist attacks. Surely, what happens with Iraq will be a major factor in the president's political fortunes next year, but if people continue to be pessimistic about the economy when Bush is in the midst of running for a second term, it will be difficult to be optimistic about his chances of winning.

单选题{{B}}Passage Two{{/B}} The vegetative forms of most bacteria are killed by drying in air, although the different species exhibit pronounced differences in their resistance. The tubercle bacillus is one of the more resistant, and vibrio cholera is one of the more sensitive to drying. In general, the encapsulated organisms are more resistant than the non-encapsulated forms. Spores are quite resistant to drying; the spores of the anthrax bacillus, for example, will germinate after remaining in a dry condition for ten years or more. The resistance of the pathogenic forms causing disease of the upper respiratory tract is of particular interest in connection with airborne infection, for the length of time that a droplet remains infective is a result, primarily, of the resistance of the particular microorganism to drying.

单选题More boys than girls are born all over the world, but a new study has found that the closer people live to the equator(赤道), the smaller the difference becomes. No one knows why. The imbalanced sex ratio at birth has been known for more than a hundred years, and researchers have found a large variety of social, economic and biological factors that relate to the sex ratio at birth-war, economic stress, age, diet, selective abortion and more. But latitude(纬度)is a natural phenomenon, unaffected by cultural or economic factors. To look at the effect of latitude, Kristen J. Navara of the University of Georgia used the latitude of the capital city in 202 countries, as well as 10 years of data on sex ratio at birth and annual variations in day length and temperature. Dr. Navara performed a statistical analysis which showed that there was a significant relation between sex ratios in favor of boys and latitude. African countries produced the lowest sex ratios—50. 7 percent boys—and European and Asian countries had the highest with 51. 4 percent. There are some possible explanations, but none entirely satisfactory. It could be that there is some survival value in producing more girls in warmer regions, but it is unclear what this might be. There may be genetic or racial differences that could explain it, but the connection persists over so many varied populations that this seems unlikely. Mice also produce more male offspring during shorter days or colder weather, but the reasons in these animals are just as mysterious as they are in humans. " There's a possibility that humans might be responding to factors they were programmed to respond to a long time ago-not cultural or socioeconomic, but climate and things like latitude," Dr. Navara said. " What's interesting is that we may be seeing something that connects us with our animal ancestry. "

单选题The chairman signed the document ______ the company.

单选题You slip the key into the ignition and crank the engine to life. But before you put the ear into gear, you tap a key on the keyboard mounted by the steering wheel, and your newest e-mail flashes up on the windscreen. This seductive satyr is what you get when you cross a ear and a eomputer. Dubbed the "network vehiele", or net-mobile, it may soon come to a driveway near you ( probably the one belonging to your rich neighbor). In a net-mobile, a motorist could tap into a regional road system but also to map out a route around rush-hour traffic snags. Drivers and passengers will be able to send and receive e-mail, track the latest sports scores or stock quotes, surf the Web, and even play video games. Or so, at least, say a number of computer-industry firms such as Microsoft, Sun, IBM and Netseape. The modern car is already an electronic showcase on wheels. On-board microcomputers improve fuel economy and reduce emissions. They operate anti-lock brake systems, and on some ears even regulate the firmness of the shock absorbers. But much of the technology needed to add extra is available now. A prototype network vehicle, produced by a consortium of Netseape, Sun, IBM and Delco (an automotive electronics firm based in Michigan), was introduced at the recent annual computer industry show in Las Vegas. It not only offered such desktop-eomputer-like services as e-mail, but allowed a driver to use them without looking away from the road. It was operated by voice commands and projected its data on to the windscreen, using the same sort of head-up display system found in modern fighter jets. Members of the consortium think a real-world network vehicle could be in production in as little as four years. Car-makers have already begun rolling out some of the features found on these prototype net mobiles. If the driver of a General Motors car equipped with its On-Star system locks his key in the car, for example, an emergency centre can transmit a digital signal to unlock the doors. On-star also calls automatically for help if an accident triggers the airbags. Toyota and General Motors are among a growing list of firms offering such in-ear navigation systems. And in Europe, BMW and Mercedes-Benz recently introduced navigation hardware that can not only plot out a route, but alert a driver to traffic jams.
