单选题For most of the last 50 years, globalization has been a win-win proposition, making America richer while lifting hundreds of millions in the developing world out of poverty and despair. Recently, however, it has begun to operate differently, undermining U.S. welfare while creating imbalances likely to end in a global economic crisis. In this new mode, globalization is tilting the world like a giant sliding board game on which the "flattening" of old barriers is accelerating the transfer of the supply side of the U.S. economy to the rest of the world, especially Asia. Take the semiconductor king, Intel, as an example. When economists and political leaders say American industry should concentrate on producing very-high-technology products where it has a clear comparative advantage, Intel's chips are what they have in mind. Yet company executives recently told a presidential advisory panel that under present circumstances they must consider building more of their new factories abroad. Over the next 10 years, they explained, the cost of running a semiconductor factory in the United States could be $1 billion more than that of running it abroad. That there is something odd here is not yet widely acknowledged. Indeed, most business, academic, media and political leaders continue to insist that globalization is proceeding smoothly, making the world rich, more democratic and more peaceful. Nor is this view entirely unjustified. U.S. GDP and productivity growth are the highest in the developed economies, while inflation, unemployment and interest rates are among the lowest. Nevertheless, a closer look reveals a dark side. The U.S. trade deficit is now more than $800 billion, or 7 percent of GDP, and grows inexorably as Americans continue to consume more than they produce. Economists typically expect the United States to import commodities and cheap manufactured goods while exporting high-tech products, sophisticated services and agricultural goods, for which its land and climate are well suited. In reality, the U.S. high-tech trade surplus of $30 billion in 1998 has collapsed to a deficit of about $40 billion. Agricultural trade is now also in deficit for the first time in memory, and the modest surplus in services is declining as global deployment of the high-speed Internet has made it possible for services to move offshore as easily as manufacturing. Some economists speak bravely of a "soft landing". In this scenario, the United States reduces its budget deficit and excess consumption, while a gradually falling dollar results in rising exports to foreign markets where governments are stimulating consumption. While desirable, this will not occur automatically. Thus, for the sake not only of the United States but of all nations with a stake in globalization, it is imperative that political leaders change its current mode. The game cannot continue with one participant playing consumer while nearly all the others play producer. For the long-term success of all, everyone must agree to play the same globalization game.

单选题Of all the components of a good night"s sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated this revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just "mental noise"—the random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind"s emotional thermostat, regulating moods while the brain is "off-line". And one leading authority says that these intensely powerful mental events can be not only harnessed but to help us sleep and feel better. "It"s your dream," says Rosalind Cartwright, chaff of psychology at Chicago"s Medical Center, "If you don"t like it, change it." Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement) sleep—when most vivid dreams occur—as it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the "emotional brain") is specially active, while the prefrontal cortex (the center of intellect and reasoning) is relatively quiet. "We wake up from dreams happy or depressed, and those feelings can stay with us all day," says Stanford sleep researcher Dr. William Dement. The link between dreams and emotions shows up among the patients in Cartwright"s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don"t always think about the emotional significance of the day"s events—until, it appears, we begin to dream. And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep. At the end of the day, there"s probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "we wake up in panic," Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people"s anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep—or rather dream—on it and you"ll feel better in the morning.

单选题Surveying the battleground at Gettysburg in 1863, Pres. Abraham Lincoln said: "The world will little note, nor long remember, what we say here, but it can never forget what they did here." Alas, he may have been right—not only has his short speech been pretty much forgotten, but also has the Civil War that inspired it. More than 100 years after the conflict, a Gallup poll of American college seniors found that 42% couldn't date the war to the correct half-century. In 2001, sampling 12-to 17-year-olds, the Colonial Williamsburg Foundation discovered that nearly one in four students didn't even know the Civil War had been fought between the North and the South. Thirteen percent figured that it was the US against Great Britain, while five percent guessed it was East vs. West. In the same poll, over 5,000,000 US teenagers were clueless about the Fourth of July. Fourteen percent thought we had declared our independence from France; three percent, from Native Americans; and one percent, from Canada. So much for 1776! It's not just early history that students get failing grades on. Americans of all ages even draw a blank when it comes to the 20th century. Questioned in 1995, 60% of adults couldn't name the president who ordered the dropping of the first atomic bomb (Harry S. Truman). Even worse, 20% didn't know where—or even if—such a bomb had ever been used. The shocking results of these surveys show Americans are suffering from a disease called "cultural amnesia," the social equivalent of Alzheimer's disease. Unlike Alzheimer's, though, it afflicts the young as well as the old. Debilitating and progressive, the malady is eating away at America's soul, for just as an individual needs memories to maintain a sense of personal identity, so does a nation need them in order to survive. Survival means having a sense of continuity. As Civil War historian Bruce Catton put it, "The American story is above all other things a continued story. It did not start with us and it will not end with us." To sense this continuity, we need to know our history, for the selfrealization of a nation is based on keeping faith with the unfulfilled dreams and sacrifices of the past. It is to this idea that Lincoln referred in the Gettysburg Address when he spoke of the "unfinished work" that must be done if "this nation…shall have a new birth of freedom." Yet, when a national civics test was administered in 1998, 35% of high school seniors failed. As educational researcher Diane Rayitch reported: "Only nine percent of the kids were able to give two reasons why it is important for citizens to be involved in a democratic society." Combined with their historical ignorance, the civic disengagement of America's young leaves their country's future in peril. More so than any other system of government, a democracy relies on the wisdom and judgment of its people. To quote another president, Thomas Jefferson, "If a nation expects to be ignorant and free, in a state of civilization, it expects what never was and never will be."
