单选题No woman can be too rich or too thin. This saying often attributed to the late Duchess of Windsor embodies much of the odd spirit of our times. Being thin is deemed as such virtue. The problem with such a view is that some people actually attempt to live by it. I myself have fantasies of slipping into narrow designer clothes. Consequently, I have been on a diet for the better—or worse—part of my life. Being rich wouldn"t be bad either, but that won"t happen unless an unknown relative dies suddenly in some distant land leaving me millions of dollars. Where did we go off the track? When did eating butter become a sin, and a little bit of extra flesh unappealing. If not repellent? All religions have certain days when people refrain from eating, and excessive eating is one of Christianity"s seven deadly sins. However until quite recently, most people had a problem getting enough to eat. In some religious groups, wealth was a symbol of probable salvation and high morals, and fatness a sign of wealth and well-being. Today the opposite is true. We have shifted to thinness as our new mark of virtue. The result is that being fat—or even only somewhat overweight—is bad because it implies a tack of moral strength. Our obsession with thinness is also fueled by health concerns. It is true that in this country we have more overweight people than ever before, and that, in many cases, being overweight correlates with an increased risk of heart and blood vessel diseases. These diseases, however, may have as much to do with our way of life and our high-fat diets as with excess weight. And the associated risk of cancer in the digestive system may be more of a dietary problem—too much fat and a lack of fiber—than a weight problem. The real concern, then, is not that we weigh too much, but that we neither exercise enough nor eat well. Exercise is necessary for strong bones and both heart and lung health. A balanced diet without a lot of fat can also help the body avoid many diseases. We should surely stop paying so much attention to weight. Simply being thin is not enough. It is actually hazardous if those who get (or already are) thin think they are automatically healthy and thus free from paying attention to their overall lifestyle. Thinness can be pure vainglory.

单选题When it comes to the slowing economy, Ellen Spero isn't biting her nails just yet. But the 47-year-old manicurist isn't cutting, filling or polishing as many nails as she'd like to, either. Most of her clients spend $ 12 to $ 50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. "I'm a good economic indicator," she says, "I provide a service that people can do without when they're concerned about saving some dollars. " So Spero is downscaling, shopping at middle-brow Dillard's department store near her suburban Cleveland home, instead of Neiman Marcus. "I don't know if other clients are going to abandon me, too," she says. Even before Alan Greenspan's admission that America's red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealerships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue between Thanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7 percent from last year's pace. But don't sound any alarms just yet. Consumers seem only concerned, not panicked, and many say they remain optimistic about the economy's long-term prospects even as they do some modest belt-tightening. Consumers say they're not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, "there's a new gold rush happening in the $4 million to $ 10 million range, predominantly fed by Wall Street bonuses," says broker Barbara Corcoran. In San Francisco, prices are still rising even as frenzied overbidding quiets. "Instead of 20 to 30 offers, now maybe you only get two or three," says John Tealdi, a Bay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job. Many folks see silver linings to this slowdown. Potential home buyers would cheer for lower interest rates. Employers wouldn't mind a little fewer bubbles in the job market. Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too. Getting a table at Manhattan's hot new Alain Ducasse restaurant need to be impossible. Not anymore. For that, Greenspan & Co. may still be worth toasting.

单选题4 Some African Americans have had a profound impact on American society, changing many people's views on race, history and politics. The following is a sampling of African Americans who have shaped society and the world with their spirit and their ideals. Muhammad Ali Cassius Marcellus Clay grew up a devout Baptist in Louisville, Ken- tucky, learning to fight at age 12 after a police officer suggested he learn to defend himself. Six years later, he was an Olympic boxing champion, going on to win three world heavyweight titles. He became known as much for his swagger (趾高气昂) outside the ring as his movement in it, converting to Islam in 1965, changing his name to Muhammad All and refusing to join the U.S. Army on religious grounds. Ali remained popular after his athletic career ended and he developed Parkinson's disease, even lighting the Olympic torch at the 1996 Atlanta Olympics and conveying the peaceful virtues of Islam following the September 11 terrorist attacks. W. E. B. Du Bois Born William Edward Burghardt Du Bois in 1868, this Massachusetts native was one of the most prominent, prolific intellectuals of his time. An academic, activist and historian, Du Bois co-founded the National Association for the Advancement of Colored People (NAACP), edited The Crisis magazine and wrote 17 books, four journals and many other scholarly articles. In perhaps his most famous work, The Souls of Black Folk, published in 1903, he predicted "the problem of 20th century [would be] the problem of the color-line. " Martin Luther King Jr. The Rev. Martin Luther King Jr. is considered one of the most powerful and popular leaders of the American civil rights movement. He spearheaded (带头，作先锋) a massive, nonviolent initiative of marches, sitins, boycotts and demonstrations that profoundly affected Americans' attitudes toward race relations. He was awarded the Nobel Peace Prize in 1964. Malcolm X Black leader Malcolm X spoke out about the concepts of race pride and black nationalism in the early 1960s. He denounced the exploitation of black people by whites and developed a large and dedicated following, which continued even after his death in 1965. Interest in the leader surged again after Spike Lee's 1992 movie Malcolm X was released. Jaekie Robinson In 1947, Jackie Robinson broke the color barrier by joining the Brooklyn Dodgers, becoming the first black baseball player in the U. S. major leagues. After retirement from baseball in 1957, he remained active in civil rights and youth activities. In 1962, he became the first African-American to be inducted into the Baseball Hall of Fame.

单选题in science the meaning of the word "explain" suffers with civilization"s every step in search of reality. Science cannot really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of their nature no more is known to the modem scientist than to Thales who first speculated on the electrification of amber. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces "really" are. "Electricity," Bertrand Russell says, "is not a thing, like St. Paul"s Cathedral; it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances they are electrified, we have told all there is to tell." Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believed that man could arrive at an understanding of reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, hence one can deduce that objects fall to the ground because that"s where they belong, and smoke goes up because that"s where it belongs. The goal of Aristotelian science was to explain why things happen. Modem science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment which now forms the basis of scientific investigation.
