单选题The current emergency in Mexico City that has taken over our lives is nothing. I could ever have imagined for me or my children. We are living in an environmental crisis, an air-pollution emergency of unprecedented severity. What it really means is that just to breathe here is to play a dangerous game with your health. As parents, what terrorizes us most is reports that children are at higher risk because they breathe more times per minute. What more can we do to protect them and ourselves? Our pediatrician"s (儿科医师的) medical recommendation was simple: abandon the city permanently. We are foreigners and we are among the small minority that can afford to leave. We are here because of my husband"s work. We are fascinated by Mexico—its history and rich culture. We know that for us, this is a temporary danger. However, we cannot stand for much longer the fear we feel for our boys. We cannot stop them from breathing. But for millions, there is no choice. Their lives, their jobs, their futures depend on being here. Thousands of Mexicans arrive each day in this city, desperate for economic opportunities. Thousands more are born here each day. Entire families work in the streets and practically live there. It is a familiar sight: as parents hawk goods at stoplights, their children play in the grassy highway dividers, breathing exhaust fumes. I feel guilty complaining about my personal situation. We won"t be here long enough for our children to form the impression that skies are colored only gray. And yet the government cannot do what it must to end this problem. For any country, especially a developing Third World economy like Mexico, the idea of barring from the capital city enough cars, closing enough factories and spending the necessary billions on public transportation is simply not an option. So when things get bad, as in the current emergency, Mexico takes half measures—prohibiting some more cars from circulating, stopping some factories from producing—that even its own officials concede aren"t adequate. The word "emergency" implies the unusual. But when daily life itself is an emergency, the concept loses its meaning. It is human nature to try to adapt to that which we cannot change. Or to mislead ourselves into believing we can adapt.

单选题Cirque du Soleil (say it: Serk du So-lay) is being accused of out-dated thinking about the dangers of AIDS. It is a modem acrobatic circus from Canada that tours in the United States and other countries. Last April, the company fired Matthew Cusick because he was HIV positive. This was after he spent four months learning his part in an act. A spokesman for the circus said Cusick was fired for safety reasons. They said he was a danger to others. He disagreed. Hundreds of people picketed a show in San Francisco. They said that firing him was not legal. Cusick says the company knew he was HIV positive when they hired him. R was not fair to let him put so much time into learning his act, and then fire him before he performed. He says he is not a danger to others. People can only get AIDS if infected blood contacts another person's blood, or open wound. The company says what their acrobats do is very, very dangerous. They perform tricks without nets. Someone might fall and get hurt. It could be bloody. They say it is too risky to let a person with HIV take part in an act. People who run the circus say it hurts to be accused of discrimination, Matthew Cusick says he feels hurt that he can't perform in the big blue and yellow tent. Dozens of artists, actors, writers and entertainers got involved in protesting the firing of Matthew Cusick, Some names you might know are: the Actors' Equity Union (45,000 members), Rosie O'Donnell, Rod McKuen, and Chad Allen, They also protested at a showing in Orange County. They said "HIV discrimination is unacceptable./

单选题AMERICA'S central bank sent a clear message this week. For the second consecutive meeting, the Federal Open Market Committee, the central bank's policy-making committee, left short-term interest rates unchanged at 1.75%. But it said that the risks facing the economy had shifted from economic weakness to a balance between weakness and excessive growth. This shift surprised no one. But it has convinced many people that interest rates are set to rise again--and soon. Judging by prices in futures markets, investors are betting that short-term interest rates could start rising as early as May, and will be 1.25 percentage points higher by the end of the year. That may be excessive. Economists at Goldman Sachs, who long argued that the central bank would do nothing this year, now expect short-term rates to go up only 0.75% this year, starting in June. But virtually everyone reckons some Fed tightening is in the offing. The reason? After an unprecedented 11 rate-cuts in 2001, short-term interest rates are abnormally low. As the signs of robust recovery multiply, analysts expect the Fed to take back some of the rate-cuts it used as an "insurance policy" after the September 11th terrorist attack. They think there will be a gradual move from the Fed's current "accommodative" monetary stance to a more neutral policy. And a neutral policy, many argue, ultimately implies short-term interest rates of around 4%. Logical enough. But higher rates could still be further off, particularly if the recovery proves less robust than many hope. Certainly, recent economic indicators have been extraordinarily strong, unemployment fell for the second consecutive month in February and industrial production rose in both January and February. The manufacturing sector is growing after 18 months of decline. The most optimistic Wall Streeters now expect GDP to have expanded by between 5% and 6% on an annual basis in the first quarter. But one strong quarter does not imply a sustainable recovery. In the short term, the bounce-back is being driven by a dramatic restocking of inventories. But it can be sustained only if corporate investment recovers and consumer spending stays buoyant. With plenty of slack capacity around and many firms stuck with huge debts and lousy profits, it is hard to see where surging investment will come from. And, despite falling unemployment, America's consumers could disappoint the bulls. These uncertainties alone suggest the central bank will be cautious about raising interest rates. Indeed, given the huge pressure on corporate profits, the Federal Reserve might be happy to see consumer prices rise slightly. In short, while Wall Street frets about when and how much interest rates will go up. The answer may well be not soon and not much.

单选题Tattoos didn't spring up with the biker gangs and rock 'n' roll bands. They've been around for a long time and had many different meanings over the course of history. For years, scientists believed that Egyptians and Nubians were the first people to tattoo their bodies. Then, in 1991, a mummy was discovered, dating back to the Bronze Age of about 3,300 B.C. "The Iceman," as the specimen was called, had several markings on his body, including a cross on the inside of his knee and lines on his ankle and back. It is believed these tattoos were made in a curative (治病的) effort. Being so advanced, the Egyptians reportedly spread the practice of tattooing throughout the world. The pyramid-building third and fourth dynasties of Egypt developed international nations with Crete, Greece', Persia and Arabia. The art tattooing stretched out all the way to Southeast Asia by 2,000B.C. Around the same time, the Japanese became interested in the art but only for its decorative attributes, as opposed to magical ones. The Japanese tattoo artists were the undisputed masters. Their use of colors, perspective, and imaginative designs gave the practice a whole new angle. During the first millenniumA.D., Japan adopted Chinese culture in many aspects and confined tattooing to branding wrongdoers. In the Balkans, the Thracians had a different use for the craft. Aristocrats, according to Herodotus, used it to show the world their social status. Although early Europeans dabbled with tattooing, they truly rediscovered the art form when the world exploration of the post-Renaissance made them seek out new cultures. It was their meeting with Polynesian that introduced them to tattooing. The word, in fact is derived from the Polynesian word tattau, which means "to mark." Most of the early uses of tattoos were ornamental. However, a number of civilizations had practical applications for this craft. The Goths, a tribe of Germanic barbarians famous for pillaging Roman settlements, used tattoos to mark their slaves. Romans did the same with slaves and criminals. In Tahiti, tattoos were a rite of passage and told the history of the person's life. Reaching adulthood, boys got one tattoo to commemorate the event. Men were marked with another style when they got married. Later, tattoos became the souvenir of choice for globe-trotting sailors. Whenever they would reach an exotic locale, they would get a new tattoo to mark the occasion. A dragon was a famous style that meant the sailor had reached a "China station." At first, sailors would spend their free time on the ship tattooing themselves and their mates. Soon after, tattoo parlors were set up in the area, surrounding ports worldwide. In the middle of the 19th century, police officials believed that half of the criminal underworld in New York City had tattoos. Port areas were renowned for being rough places flail of sailors that were guilty of some crime or another. This is most likely how tattoos got such a bad reputation and became associated with rebels and criminals.

单选题4 The history of responses to the work of the artist Sandro Botticelli (1444—1510) sug gests that widespread appreciation by critics is a relatively recent phenomenon. Writing in 1550, Vasari expressed an unease with Botticelli's work, admitting that the artist fitted awkwardly into his evolutionary scheme of the history of art. Over the next two centuries, academic art historians defamed Botticelli in favor of his fellow Florentine, Michelange lo. Even when anti-academic art historians of the early nineteenth century rejected many of the standards of evaluation adopted by their predecessors, Botticelli's work remained out side of accepted taste, pleasing neither amateur observers nor connoisseurs. (Many of his best paintings, however, remained hidden away in obscure churches and private homes. ) The primary reason for Botticelli's unpopularity is not difficult to understand, most observers, up until the mid-nineteenth century, did not consider him to be noteworthy, because his work, for the most part, did not seem to these observers to exhibit the tradi tional characteristics of fifteenth-century Florentine art. For example, Botticelli rarely em ployed the technique of strict perspective and, unlike Michelangelo, never used chiaroscuro. Another reason for BotticeiIi's unpopularity may have been that his attitude toward the style of classical art was very different from that of his contemporaries. Although he was thoroughly exposed to classical art, he showed little interest in borrowing from the classi cal style. Indeed, it is paradoxical that a painter of large-scale classical subjects adopted a style that was only slightly similar to that of classical art. In any case, when viewers began to examine more closely the relationship of Botticelli's work to the tradition of fifteenth-century Florentine art, his reputation began to grow. Analyses and assessments of Botticelli made between 1850 and 1870 by the artists of the Pre-Raphaelite movement, as well as by the writer Pater (although he, unfortu nately, based his assessment on an incorrect analysis of Botticelli's personality), inspired a new appreciation of Botticelli throughout the English-speaking world. Yet Botticelli's work, especially the Sistine frescoes, did not generate worldwide attention until it was fi nally subjected to a comprehensive and scrupulous analysis by Home in 1908. Home rightly demonstrated that the frescoes shared important features with paintings by other fifteenth century Florentines—features such as skillful representation of anatomical proportions, and of the human figure in motion. However, Home argued that Botticelli did not treat these qualities as ends in themselves—rather, that he emphasized clear depletion of a sto ry, a unique achievement and one that made the traditional Florentine qualities less cen- tral. Because of Home's emphasis crucial to any study of art, the twentieth century has come to appreciate Botticelli's achievements.
