单选题 It was a fixing sight: there, in the Capitol itself, a U.S. Senator often mocked for his halting, inarticulate speaking, reached deep into his Midwestern roots and spoke eloquently, even poetically, about who he was and what he believed, stunning politicians and journalists alike. I refer, of course, to Senator Jefferson Smith. In Frank Capra's classic Mr. Smith Goes to Washington, Jimmy Stewart plays this simple, idealistic small-town American, mocked and scorned by the big-moneyed, oh-so-sophisticated power elite--only to triumph over a corrupt Establishment with his rock-solid goodness. At root, it is this role that soon-to-be-ex-Senator Bob Dole most aspires to play: the self effacing, quietly powerful small-town man from {{U}}Main Street{{/U}} who outwits the cosmopolitan, slick-talking snob from the {{U}}fleshpots{{/U}}. And why not? There is, after all, no more enduring American icon. How enduring? Before Americans had a Constitution, Thomas Jefferson was arguing that the new nation's future would depend on a base of agrarian yeomen free from the vices inherent in big cities. In 1840 one of the classic, image-driven presidential campaigns featured William Henry Harrison as the embodiment of rural virtues, the candidate of the log cabin and hard cider, defeating the incumbent Martin Van Buren, who was accused of dandified dress and manners. There is, of course, a huge disconnect between this professed love of the simple, unspoiled life and the way Americans actually live. As a people, Americans have spent the better part of the 20th century deserting the farms and the small towns for the cities and the suburbs; and are torn between vacationing in Disney World and Las Vegas. U.S. politicians too haven't exactly shunned the temptations of the cosmopolitan life. The town of Russell, Kansas, often seems to be Dole's running mate, but the candidate spends his leisure time in a luxury condominium in Bal Harbor, Florida. Bill Clinton still believes in a place called Hope, but the spiffy, celebrity-dense resorts of Martha's Vineyard and Jackson Hole are where he kicks back. Ronald Reagan embodied the faith-and-family pieties of the front porch and Main Street, but he fled Iowa for a career and a life in Hollywood. Still, the hunger for the way Americans believe they are supposed to live is strong, and the distrust of the intellectual hustler with his airs and his high-flown language runs deep. It makes sense for the Dole campaign to make this a contest between Dole as the laconic, quiet man whose words can be trusted and Bill Clinton as the traveling salesman with a line of smooth patter but a suitcase full of damaged goods. It makes sense for Dole to make his campaign song Thank God I'm a Country Boy--even if he is humming it 9,200 m up in a corporate jet on his way to a Florida condo.

单选题Many Americans regard the jury system as a concrete expression of crucial democratic values, including the principles that all citizens who meet minimal qualifications of age and literacy are equally competent to serve on juries; that jurors should be selected randomly from a representative cross section of the community; that no citizen should be denied the right to serve on a jury on account of race, religion, sex, or national origin; that defendants are entitled to trial by their peers; and that verdicts should represent the conscience of the community and not just the letter of the law. The jury is also said to be the best surviving example of direct rather than representative democracy. In a direct democracy, citizens take turns governing themselves, rather than electing representatives to govern for them. But as recently as in 1986, jury selection procedures conflicted with these democratic ideals. In some states, for example, jury duty was limited to persons of supposedly superior intelligence, education, and moral character. Although the Supreme Court of the United States had prohibited intentional racial discrimination in jury selection as early as the 1880 case of Strauder v. West Virginia, the practice of selecting so-called elite or blue-ribbon juries provided a convenient way around this and other antidiscrimination laws. The system also failed to regularly include women on juries until the mid-20th century. Although women first served on state juries in Utah in 1898, it was not until the 1940s that a majority of states made women eligible for jury duty. Even then several states automatically exempted women from jury duty unless they personally asked to have their names included on the jury list. This practice was justified by the claim that women were needed at home, and it kept juries unrepresentative of women through the 1960s. In 1968, the Congress of the United States passed the Jury Selection and Service Act, ushering in a new era of democratic reforms for the jury. This law abolished special educational requirements for federal jurors and required them to be selected at random from a cross section of the entire community. In the land-mark 1975 decision Taylor v. Louisiana, the Supreme Court extended the requirement that juries be representative of all parts of the community to the state level. The Taylor decision also declared sex discrimination in jury selection to be unconstitutional and ordered states to use the same procedures for selecting male and female jurors.

Findings published online this week by the Proceedings of the National Academy of Sciences further support the theory that the brain organizes and stows memories formed during the day while the rest of the body is catching zzz's. Gyorgy Buzsaki of Rutgers University and his colleagues analyzed the brain waves of sleeping rats and mice. Specifically, they examined the electrical activity emanating from the somatosensory neocortex (an area that processes sensory information) and the hippocampus, which is a center for learning and memory. The scientists found that oscillation in brain waves from the two regions appear to be intertwined. So-called sleep spindles (bursts of activity from the neocortex) were followed tens of milliseconds later by beats in the hippocampus known as ripples. The team posits that this interplay between the two brain regions is a key step in memory consolidation. A second study, also published online this week by the Proceedings of the National Academy of Sciences, links age-associated memory decline to high glucose levels. Previous research had shown that individuals with diabetes suffer from increased memory problems. In the new work, Antonio Convit of New York University School of Medicine and his collaborators studied 30 people whose average age was 69 to investigate whether sugar levels, which tend to increase with age, affect memory in healthy people as well. The scientists administered recall tests, brain scans and glucose tolerance tests, which measure how quickly sugar is absorbed from the blood by the body's tissues. Subjects with the poorest memory recollection, the team discovered, also displayed the poorest glucose tolerance. In addition, their brain scans showed more hippocampus shrinkage than those of subjects better able to absorb blood sugar. "Our study suggests that this impairment may contribute to the memory deficits that occur as people age." Convit says. "And it raises the intriguing possibility that improving glucose tolerance could reverse some age-associated problems in cognition." Exercise End weight control can help keep glucose levels in check, so there may be one more reason to go to the gym.

单选题Richard Holbrooke, who died at the age of 69 after suffering a ruptured aorta, was not the most universally beloved, but was certainly one of the ablest, 'the most admired and the most effective of American diplomats. He is one of the few of that profession in the past 40 years who can be compared with the giants of the "founding generation" of American hegemony, such as Dean Acheson and George Kennan. Holbrooke was tough as well as exceptionally bright. He was a loyal, liberal Democrat, but also a patriot who was prepared to be ruthless in what he saw as his nation's interest. To his friends, he was kind and charming, but he could be abrasive: no doubt that characteristic helped prevent him becoming Secretary of State on two occasions, under Bill Clinton and again when Barack Obama became president. He held almost every other important job in the international service of the US. He was ambassador to the United Nations, where he dealt with the vexed problem of America's debts to the organization, and to Germany. He was the only person in history to be assistant Secretary of State—the key level in routine diplomacy—in two regions of the world, Europe and Asia. He distinguished himself as an investment banker, a magazine editor, a charity executive and an author, but he will be remembered most of all for his success in negotiating an end to the war in Bosnia-Herzegovina at an Ohio airbase, and for his part in the American intervention in Kosovo. At the time of his death, he was Obama's special representative for Afghanistan and Pakistan. Holbrooke joined the Foreign Service, and in 1963 was sent as a civilian official to Vietnam, where he was one of a talented cohort of young men who were to become leaders in American diplomacy. Once back in Washington in 1966, Holbrooke worked for two years in the White House under Johnson, and then at the State Department, where he was a junior member of the delegation to the fruitless initial peace talks with North Vietnam in Paris. By 1972, Holbrooke was ready for a change. He became the first editor of the magazine Foreign Policy, created as a less stuffy competitor to the august Foreign Affairs. He also worked for Newsweek magazine. In 1976, he went to work for Governor Jimmy Carter of Georgia, who was beginning his campaign for president and badly needed some foreign policy expertise. When Carter became president, in 1977, Holbrooke became his assistant Secretary of State for Asian affairs. (425 words)
