单选题 The political crisis in Ukraine, where opposition protesters are burning campfires and setting up tents in the center of Kiev, is presenting a test for Russia, which gambled heavily on its neighbor's presidential election. A defeat of the pro-Moscow candidate, Prime Minister Viktor Yanukovych, would humiliate the Kremlin one year after another former Soviet Republic, Georgia, slipped from its influence, according to observers and political analysts. The Ukrainian upheaval echoes what happened in Georgia, where protests over vote rigging led to the resignation of a Moscow-linked President and a landslide victory of a young, Western-educated and Western-oriented leader. {{U}}For Moscow, the stakes are even higher in Ukraine.{{/U}} Unlike Georgia, Ukraine shares close ethnic and linguistic ties with Russia; Kiev, Ukraine's capital, is the cradle of the Russian culture and the ancient capital of the first Russian state. President Vladimir V. Putin of Russia wants to forge a closer union between three Slavic nations Russia, Ukraine, and tiny, authoritarian Belarns and Ukraine is key to the plan, Russian businesses have major interests in Ukraine, which borders Russia to the west. The Russian military also wants to have Ukraine as an ally over which it can hold sway, not as a potential NATO participant, the analysts said. As other former republics turned away from Russia, Moscow "gets the feeling that Ukraine is its closest ally, with a symbolic significance," said Marsha Lipman of the Carnegie Moscow Center. "Russia has given itself a goal of getting a controllable Ukraine. I'm afraid it won't happen." Putin quickly congratulated Yanukovych following Sunday's vote, which pitted the prime minister against opposition leader Viktor Yushchenko. But Western observers reported voting fraud, and hundreds of thousands of Ukrainians rallied in protest. "If the crisis lasts, .it will become a potential source of problems for Russia's relations with the West," said Alexander Pikayev, an independent politica! analyst in Moscow "Russia will have to share responsibility for the acute political crisis." The Kremlin had come out early and strongly for Yanukovych before the election. Putin traveled twice to Ukraine, ahead of each round of voting. To support the official purpose of his first visit, attending anniversary celebrations of Ukraine's liberation from the Nazis in World War Ⅱ, the festivities were rescheduled for 10 days earlier than the actual date. Since the vote, {{U}}the Kremlin's propaganda machine has been in full swing.{{/U}} Russia's Channel One television, controlled by the Kremlin like all other major networks accused the Ukrainian opposition of breaking the law by declaring Yushehenko the rightfully elected President. In his prime-time show, television commentator Mikhail Leontyev compared the Ukrainian opposition to Middle Eastern militants. "But this is not the Gaza Strip, and the chaos cannot go on indefinitely," he said, warning that protest strikes would only hurt ordinary people. Russian television also aired reports on the anniversary of Georgia's "Rose Revolution" on Tuesday, saying the country was steeped in misery and poverty a year after the fall of the old government. Russian independent newspapers, however, which reach only a fraction of the TV audience, wrote about a different Georgia the same day telling how happy Georgians had decorated shop windows and restaurants with roses to celebrate. Many Russians view Ukraine's powerful opposition as a kind of force that has disappeared in Russia under the increasingly authoritarian Putin administration. Russia has not had a seriously contested presidential election since 1996, when Boris Yeltsin narrowly defeated a Communist challenger. The political opposition here is fractured and marginalized, ousted from parliament in last year's balloting closely directed by the Kremlin. Russian optimists hope a defeat of Yanukovyeh would force the Kremlin to reconsider its attempts to control political life in other former Soviet republics. Pessimists fear that his loss would only prompt the Kremlin to tighten its rule. "The stakes are high," Lipman said. "It's a question of whether Russia's neighbor will be a Ukraine ruled not through democratic institutes but through administrative means, or a Ukraine that will embrace democracy."

单选题Today, cigarette smoking is a widespread habit. About 43 percent of the adult men and 31 percent of the adult women in the US smoke cigarettes regularly. It is encouraging to note, however, that millions of people have given up the smoking habit. 75 percent of the male population and 46 percent of the female population have smoked cigarettes at some time during their lives, but 26 percent of these men and 11 percent of the women have stopped smoking. The number of persons who have given up smoking is increasing. It is a fact that men as a group smoke more than women. Among both men and women the age group with the highest proportion of smokers is the age group 24-44. Income, education, and occupation all play a part in determining a person"s smoking habits. City people smoke more than people living on farms. Well-educated men with high incomes are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes. On the other hand, if a well-educated man with a higher income smokes at all, he is likely to smoke more packs of cigarettes per day. The situation is somewhat different for women. There are slightly more smokers among women with higher family incomes and higher education than among the lower income and lower educational groups. These more highly educated women tend to smoke more heavily. Among teenagers the picture is similar. There are fewer teenaged smokers from upper-income, well-educated families, and fewer from families living in farm areas. High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school. Children are most likely to start smoking if one or both of their parents smoke.

单选题Standard usage includes those words and expressions understood, used, and accepted by a majority of the speakers of a language in any situation regardless of the level of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, however, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be found in standard dictionaries but will be so identified. Both Colloquial usage and slang are more common in speech than in writing. Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events. It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions. First, the introduction and acceptance of new objects and situations in the society; second, a diverse population with a large number of subgroups; third, association among the subgroups and the majority population. Finally, it is worth noting that the terms "standard," "colloquial," and "slang" exist only as abstract labels for scholars who study language. Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use all three types of expressions.

单选题The Greek's lofty attitude toward scientific research—and the scientists' contempt of utility —was a long time dying. For a millennium after Archimedes, this separation of mechanics from geometry inhibited fundamental technological progress and in some areas repressed it altogether. But there was a still greater obstacle to change until the very end of the middle ages: the organization of society. The social system of fixed class relationships that prevailed through the Middle Ages(and in some areas much longer)itself hampered improvement. Under this system, the laboring masses, in exchange for the bare necessities of life, did all the productive work, while the privileged few — priests, nobles, and kings — concerned themselves only with ownership and maintenance of their own position. In the interest of their privileges they did achieve considerable progress in defense, in war making, in government, in trade, in the arts of leisure, and in the extraction of labor from their dependents, but they had no familiarity with the process of production. On the other hand, the laborers, who were familiar with manufacturing techniques, had no incentive to improve or increase production to the advantage of their masters. Thus, with one class possessing the requisite knowledge and experience, but lacking incentive and leisure, and the other class lacking the knowledge and experience, there was no means by which technical progress could be achieved. The whole ancient world was built upon this relationship — a relationship as sterile as it was inhuman. The availability of slaves nullified the need for more efficient machinery. In many of the commonplace fields of human endeavor, actual stagnation prevailed for thousands of years. Not all the glory that was Greece and the grandeur that was Rome could develop the windmill or contrive so simple an instrument as the wheelbarrow—products of the tenth and thirteenth centuries respectively. For about twenty-five centuries, two-thirds of the power of the horse was lost because he wasn't shod, and much of the strength of the ox was wasted because his harness wasn't modified to fit his shoulders. For more than rive thousand years, sailors were confined to rivers and coasts by a primitive steering mechanism which required remarkably little alteration(in the thirteenth century)to become a rudder. With any ingenuity at all, the ancient plough could have been put on wheels and the ploughshare shaped to bite and turn the sod instead of merely scratching it — but the ingenuity wasn't forthcoming. And the villager of the Middle Ages, like the men who first had fire, had a smoke hole in the center of the straw and reed thatched roof of his' one-room dwelling(which he shared with his animals), while the medieval charcoal burner(like his Stone Age ancestor)made himself a hut of small branches.

单选题As a wise man once said, we are all ultimately alone. But an increasing number of Europeans are choosing to be so at an ever earlier age. This isn"t the stuff of gloomy philosophical contemplations, but a fact of Europe"s new economic landscape, embraced by sociologists, real-estate developers and ad executives alike. The shift away from family life to solo lifestyle, observes a French sociologist, is part of the "irresistible momentum of individualism" over the last century. The communications revolution, the shift from a business culture of stability to one of mobility and the mass entry of women into the workforce have greatly wreaked havoc on Europeans" private byes. Europe"s new economic climate has largely fosterd the trend toward independence, the current generation of home-aloners came of age during Europe"s shift from social democracy to the sharper, more individualistic climate of American-style capitalism. Raised in an era of privatization and increased consumer choice, today"s tech-savvy workers have embraced a free market in love as well as economics. Modern Europeans are rich enough to afford to live alone, and temperamentally independent enough to want to do so. Once upon a time, people who lived alone tended to be those on either side of marriage-twentysometing professionals or widowed senior citizens, while pensioners, particularly elderly women, make up a large proportion of those living alone, the newest crop of singles are high earners in their 30s and 40s who increasingly view living alone as a lifestyle choice. Living alone was conceived to be negative-dark and cold, while being together suggested warmth and light. But then came along the idea of singles. They were young, beautiful, strong! Now, young people want to live alone. The booming economy means people are working harder than ever. And that doesn"t leave much room for relationships. Pirnpi Arroyo, a 35-year-old composer who lives alone in a house in Paris, says he hasn"t got time to get lonely becanse he has too much work. "I have deadlines which would make life with someone else fairly difficult. Only an Iddeal Woman would make him change his lifestyle," he says. Kaufmann, author of a recent book called "The Single Woman and Prince Charming", thinks this fierce new individualism means that people expext morn and more of mates, so relationships don"t last long--if they start at all. Eppendorf, a blond Berliner with a deep tan, teaches grade school in the mornings. In the afternoon she sunbarthes or sleeps, resting up for going dancing. Just shy of 50, she says she"d never have wanted to do what her mother did--give up a career to raise a family. Instead, "I"ve always done what I wanted to do: live a self-determined life."
