单选题The Pakistani president, Gen. Pervez Musharraf, announced here today that a delegation of Pakistani officials would fly to the Taliban~ s headquarters in the southern Afghan city of Kandahar Monday to renew demands that the militia surrender Saudi fugitive Osama Bin Laden. U.S. officials have named Bin Laden, who has been given shelter by the Taliban rulers in Afghanistan, as the prime suspect in Tuesday's terrorist attacks in Washington and New York. "We are aware of the gravity of the situation and know that in the lives of nations, such situations do arise that require making important decisions," Musharraf said at a meeting with Pakistani newspaper editors. The Taliban's leader, Mohammad Omar, has refused to give up Bin Laden, claiming he is not responsible for the U.S. attacks. "The Pakistan government is leaning on the Taliban government to hand over Osama to save this entire region from catastrophe," said Najam Sethi, editor of the weekly newspaper Friday Times, who participated in the meeting with Musharraf. "I am not sure whether there is much chance of that happening, but the pressure is on from the Pakistan government." Pakistan has been a key supporter of the Taliban, which controls more than 90 percent of Afghanistan and has enforced a strict interpretation of Islamic law in the country. Omar, the Taliban leader, today convened an emergency meeting of clerics(圣职人员) in the Afghan capital, Kabul. "As regards the possible attack by America on the sacred soil of Afghanistan, veteran honorable clerics should come to Kabul for a sharia decision," Omar said in a statement broadcast on the Taliban's Radio Shariat today. Sharia is Islamic law. Omar, who reportedly left Ms. Kandahar headquarters several days ago in anticipation of a U. S. attack, asked Afghans to pray and read the Koran to meet what he called a "test", according to the statement. He indicated he would not attend the meeting of clerics, though he reportedly met with a small group of senior clerics today. The Pakistan-based Afghan Islamic Press reported today it had received a statement from Bin Laden, dispatched by an aide from an undisclosed location in Afghanistan, in which he denied involvement in last week's attacks on the World Trade Center and the Pentagon. "I am residing in Afghanistan," the statement said, "I have taken an oath of allegiance to Omar which does not allow me to do such things from Afghanistan. We have been blamed in the past, but we were not involved./

单选题{{B}}Part C{{/B}}Directions: Read the following text carefully and then translate the underlined segments into Chinese. Your translations should be written carefully on ANSWER SHEET 2. There are many innovations turning up in the latest experimental and production electric cars, affecting everything from batteries to motors to control systems. The need to make them all work together is prompting a complete rethink about the way cars should be designed and manufactured, and it is unclear which technologies will dominate as the constraints imposed by internal combustion engines give way to the new limits and possibilities associated with electric propulsion. (46) {{U}}But one group of engineers have stuck their necks out and declared that a particular technology, the electric hub motor, is likely to become the most widely used drive system.{{/U}} At this week's Deutsche Messe technology show in Hanover, researchers at the Fraunhofer Institute displayed an electric vehicle which they are using as a test platform to investigate new vehicle systems. (47) {{U}}It includes electric hub motors, which they have developed to be markedly more powerful than any such motors currently available.{{/U}} The motors have all the necessary power and control systems integrated into the wheel hub, greatly reducing the number of connections between the hub motors and the rest of the vehicle. (48) {{U}}Because hub motors can deliver power independently to each wheel, tricks like four-wheel-drive are possible, and with software monitoring each wheel, stability and traction control can also be built-in.{{/U}} Besides dispensing with the traditional engine bay on a car, hub motors save space and weight because there is no need for a mechanical transmission, with its driveshafts and differential units. (49) {{U}}Some critics of the technology think having heavy electric motors in the wheels of cars will have a negative effect on vehicle handling.{{/U}} But Hermann Pleteit, a project manager with one of the 33 Fraunhofer research centres that have teamed up to work on the experimental car, says the chassis and many other parts of the vehicle can be configured in such a way to compensate for this. Several carmakers and component suppliers are interested in hub motors. Michelin, for one, is developing a system it calls the Active Wheel. (50) {{U}}As well as an electric motor to drive the wheel, it contains a second electric motor to operate an active suspension system that is also built into the wheel hub.{{/U}} Michelin reckons this arrangement, which is now being tested in cars, could make other conventional parts, like shock absorbers, unnecessary.

单选题Astronaut Jim Voss has enjoyed many memorable moments in his career, including three space flights and one space walk. But he recalls with special fondness a decidedly earthbound experience in the summer of 1980, when he participated in the NASA-AS-EE Summer Faculty Fellowship Program. Voss, then a science teacher at West Point, was assigned to the Marshall Space Flight Center's propulsion lab in Alabama to analyze why a hydraulic fuel pump seal on the space shuttle was working so well when previous seals had failed. It was a seemingly tiny problem among the vast complexities of running the space program. Yet it was important to NASA because any crack in the seals could have led to destructive results for the astronauts who relied on them. "I worked a bit with NASA engineers," says Voss, "but I did it mostly by analysis. I used a handheld calculator, not a computer, to do a thermodynamic analysis. "At the end of the summer, he, like the other NASA-ASEE fellows working at Marshall, summarized his findings in a formal presentation and detailed paper. It was a valuable moment for Voss because the ASEE program gave him added understanding of NASA, deepened his desire to fly in space, and intensified his application for astronaut status. It was not an easy process. Voss was actually passed over when he first applied for the astronaut program in 1978. Over the next nine years he reapplied repeatedly, and was finally accepted in 1987. Since then he has participated in three space missions. The 50-year-old Army officer, who lives in Houston, is now in training for a four-month mission as a crew member on the International Space Station starting in July 2000. Voss says the ASEE program is wonderful for all involved. "It brings in people from the academic world and gives NASA a special property for a particular period of time. It brings some fresh eyes and fresh ideas to NASA, and establishes link with our colleges and universities," Voss explains. "There's an exchange of information and an exchange of perspectives that is very important." For the academic side, Voss says, the ASEE program also "brings institutions of higher learning more insight into new technology. We give them an opportunity to work on real-world problems and take it back to the classroom. /

单选题What can be predicted from the last paragraph?

单选题Early this week a bit of cheery news was reported by the Manhattan Institute, a conservative think tank: black segregation has hit its lowest point in more than a century — declining in all 85 of the nation"s largest metropolitan areas. Nevertheless, the report is largely celebratory in tone, and it has been received in that fashion by much of the news media. Before we break out the champagne, however, it may be wise to pause and reflect for a moment on who was excluded from the analysis. Our nation"s prison population has more than quintupled (soaring from 300, 000 in the mid-1970s to more than 2 million today), due to a "get tough" movement and a war on drugs that has been waged almost exclusively in poor communities of color. Studies have consistently shown that people of color are no more likely to use or sell illegal drugs than whites, but a fierce drug war has been waged nonetheless, and harsh mandatory minimum sentences passed, leading to a prison-building boom unprecedented in world history. Despite this sea change, prisoners continue to be treated as nonentities in much sociological and economic analysis. In the Manhattan Institute study, prisoners are not even mentioned, despite the fact that millions of poor people — overwhelmingly people of color — are removed from their communities and held in prisons, often hundreds of miles from home. Most new prison construction has occurred in predominately white, rural communities, and thus a new form of segregation has emerged in recent years. Bars and walls keep hundreds of thousands away from mainstream society — a form of apartheid unlike the world has even seen. If all of them suddenly returned, they would not be evenly throughout the nation"s population. Instead they would return to a relatively small number of communities defined by race and class, greatly intensifying the levels of segregation we see today. Those who imagine that the failure to account for prisoners can"t possibly affect the analysis would be wise to consider the distortion of unemployment figures in recent years. According to Harvard professor Bruce Western, standard unemployment figures underestimate the true jobless rate by as much as 24 percentage points for less educated black men. In fact, during the 1990s — the economic-boom years — no college black men were the only group that experienced a sharp increase in unemployment, a development directly traceable to the sudden explosion of the prison population. At the same time that unemployment rates were sinking to record low levels for the general population, the true jobless rate among no college black men soared to a staggering 42%. Prisoners do matter when analyzing the severity of racial inequality in the U. S. Yet because they are out of sight and out of mind, it is easy to imagine that we are making far more racial progress than we actually are. For now, let"s keep the cork in the bottle and pray that we will eventually awaken from our color-blind slumber to the persistent realities of race in America.

单选题Everyone has heard of the San Andreas fault, which constantly threatens California and the West Coast with earth- quakes. But how many people know about the equally serious New Madrid fault in Missouri.'? Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River. Property damage was severe. Buildings in the area were almost dest oyed. Whole forests fell at once, and huge cracks opened in the ground, allowing smell of sulfur to filter upward. The Mississippi River itself completely changed character, developing sudden rapids and whirlpools. Several times it changed its course, and once, according to some observers, it actually appeared to run backwards. Few people were killed in the New Madrid earthquakes, probably simply because few people lived in the area in 1811; but the severity of the earth- quakes are shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast. Buildings shook in New York City, and clocks were stopped in Washington D.C. Scientists now know that America's two major faults are essentially different. The San Andreas is a horizontal boundary between two major land masses that are slowly moving in opposite directions. California earthquakes result when the movement of these two masses suddenly lurches forward. The New Madrid fault, on the other hand, is a vertical fault; at some point, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface. Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks. Even now', the rock continues to settle downwards, and sudden sinking motions trigger earthquakes in the region. The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern Illinois. Scientists who have studied the New Madrid fault say there have been numerous smaller quakes in the area since 1811; these smaller quakes indicate that larger ones are probably coming, but rite scientists say they have no method of predicting when a large earthquake will occur.

单选题It may turn out that the "digital divide"—one of the most fashionable political slogans of recent years—is largely fiction. As you will recall, the argument went well beyond the unsurprising notion that the rich would own more computers than the poor. The disturbing part of the theory was that society was dividing itself into groups of technology "haves" and "have-nots" and that this segregation would, in turn, worsen already large economic inequalities. It is this argument that is either untrue or wildly exaggerated. We should always have been suspicious. After all, computers have spread quickly because they have become cheaper to buy and easier to use. Falling prices and skill requirements suggest that the digital divide would spontaneously shrink—and so it has. Now, a new study further discredits the digital divide. The study, by economist David Card of the University of California, Berkeley, challenges the notion that computers have significantly worsened wage inequality. The logic of how this supposedly happens is straightforward: computers raise the demand for high-skilled workers, increasing their wages. Meanwhile, computerization—by automating many routine tasks—reduces the demand for low-skilled workers and, thereby, their wages. The gap between the two widens. Superficially, wage statistics support the theory. Consider the ratio between workers near the top of the wage distribution and those near the bottom. Computerization increased; so did the wage gap. But wait, point out Card and DiNardo. The trouble with blaming computers is that the worsening of inequality occurred primarily in the early 1980s. With computer use growing, the wage gap should have continued to expand, if it was being driven by a shifting demand for skills. Indeed, Card and DiNardo find much detailed evidence that contradicts the theory. They conclude that computerization does not explain "the rise in U.S. wage inequality in the last quarter of the 20th century." The popular perception of computers' impact on wages is hugely overblown. Lots of other influences count for as much, or more. The worsening of wage inequality in the early 1980s, for example, almost certainly reflected the deep 1981—1982 recession and the fall of inflation. Companies found it harder to raise prices. To survive, they concluded that they had to hold down the wages of their least skilled, least mobile and youngest workers. The "digital divide" suggested a simple solution (computers) for a complex problem (poverty). With more computer access, the poor could escape their lot. But computers never were the source of anyone's poverty and, as for escaping, what people do for themselves matters more than what technology can do for them.

单选题The provision of positive incentives to work in the new society will not be an easy task. But the most difficult task of all is to devise the ultimate and final sanction to replace the ultimate sanction of hunger--the economic whip of the old dispensation. Moreover, in a society which rightly rejects the pretence of separating economies from politics and denies the autonomy of the economic order, that sanction can be found only in some conscious act of society. We can no longer ask the invisible hand to do our dirty work for us. I confess that I am less horror-struck than some people at the prospect, which seems to me unavoidable, of an ultimate power of what is called direction of labor resting in some arm of society, whether in an organ of state or of trade unions. I should indeed be horrified if I identified this prospect with a return to the conditions of the pre-capitalist era. The economic whip of laissea-faire undoubtedly represented an advance on the serf-like conditions of that period: in that relative sense, the claim of capitalism to have established for the first time a system of "free" labour deserves respect But the direction of labour as exercised in Great Britain in the Second World War seems to me to represent as great an advance over the economic whip of the heyday of capitalist private enterprise as the economic whip represented over pre-capitalist serfdom, Much depends on the effectiveness of the positive incentives, much, too, on the solidarity and self-discipline of the community. After all, under the system of laissea-faire capitalism the fear of hunger remained an ultimate sanction rather than a continuously operative force. It would have been intolerable if the worker had been normally driven to work by conscious fear of hunger; nor, except in the early and worst days of the Industrial Revolution, did that normally happen. Similarly in the society of the future the power of direction should be regarded not so much as an instrument of daily used but rather as an ultimate sanction held in reserve where voluntary methods fail It is inconceivable that, in any period or in any conditions that can now be foreseen, any organ of state in Great Britain would be in a position, even if it had the will, to marshal and deploy the labour force over the whole economy by military discipline like an army in the field. This, like other nightmares of a totally planned economy, can be left to those who like to frighten themselves and others with scarecrows.
