单选题The old man______the events of the time in accordance with his peculiar ideas.

单选题The changes in globally averaged temperature that have occurred at the Earth"s surface over the past century are similar in size and timing to those 21 by models that take into account the combined influences of human factors and solar variability. To 22 the question of attribution requires the 23 of more powerful and complex methods, beyond the use of global averages alone. New studies have focused on 24 maps or patterns of temperature change in 25 and in models. Pattern analysis is the climatologically equivalent of the more comprehensive tests in the medical analogy mentioned 26 , and makes it possible to achieve more definitive 27 of observed climate changes to a particular cause or causes. The expected influence of human activities is thought to be much more complex than uniform warming over the entire surface of the Earth and over the whole 28 cycle. Patterns of change over space and time therefore provide a more powerful 29 technique. The basic idea 30 pattern-based approaches is that different 31 causes of climate change have different characteristic patterns of climate response or fingerprints. Attribution studies seek to 32 a fingerprint match between the patterns of climate change 33 by models and those actually observed. The most recent assessment of the science suggests that human activities have led to a discernible 34 on global climate and that these activities will have and increasing influence on future climate. The burning of coal, oil and natural gas, as well as various agricultural and industrial practices, are 35 the composition of the atmosphere and contributing to climate change, These human activities have led to increased atmospheric 36 of a number of greenhouse gases, including carbon dioxide, methane and so on in the lower atmosphere. Human activities, such as the burning of fossil, have also increased the 37 of small particles in the atmosphere. These particles can change the 38 of energy that is absorbed and reflected by the atmosphere. They are also believed to modify the 39 of air and clouds, changing the amount of energy that they absorb and reflect. Intensive studies of the climatic effects of these particles began only recently and the overall 40 is uncertain. It is likely that the net effect of these small particles is to cool the climate and to partially offset the warming of increasing concentrations of greenhouse gases.

单选题"Before, we were too black to be white. Now, we're too white to be black." Hadija, one of South Africa's 3.5m Coloured (mixed race) people, sells lace curtains at a street market in a bleak township outside Cape Town. In 1966 she and her family were driven out of District Six, in central Cape Town, by an apartheid government that wanted the area for whites. Most of the old houses and shops were bulldozed but a Methodist church, escaping demolition, has been turned into a little museum, with and old street plan stretched across the floor. On it, families have identified their old houses, writing names and memories in bright felt-tip pen. "We can forgive, but not forget," says one. Up to a point. In the old days, trampled on by whites, they were made to accept a second-class life of scant privileges as a grim reward for being lighter-skinned than the third-class blacks. Today, they feel trampled on by the black majority. The white-led National Party; which still governs the Western Cape, the province where some 80% of Coloureds live, plays on this fear to good electoral effect. With no apparent irony, the party also appeals to the Coloured sense of common culture with fellow Afrikaans-speaking whites, a link the Nats have spent decades denying. This curious courtship is again in full swing. A municipal election is to be held in the province on May 29th and the Nats need the Coloured vote if they are to win many local councils. By most measures, Coloureds are still better-off than blacks. Their jobless rate is high, 21% according to the most recent figures available. But the black rate is 38%. Their average yearly income is still more than twice that of blacks. But politics turns on fears and aspirations. Most Coloureds fret that affirmative action, the promotion of non-whites into government-related jobs, is leaving them behind. Affirmative action is supposed to help Coloureds (and Indians) too. It often does not. They may get left off a shortlist because, for instance, a job requires the applicant to speak a black African language, such as Xhosa. Some Coloureds think that the only way they will improve their lot is to launch their own, ethnically based, political parties, last year a group formed the Kleurling Weerstandsbeweging, or Coloured Resistance Movement. But in-fighting caused this to crumble: some members wanted it to promote Goloured interests and culture; others to press for an exclusive "homeland". In fact, the coloureds' sense of collective identity is undefined, largely imposed by apartheid's twisted logic. They are descended from a mix of races, including the Khoi and San (two indigenous African peoples), Malay slaves imported by the Dutch, and white European settlers. And though they do indeed share much with Afrikaners-many belong to the Dutch Reformed Church and many speak Afrikaans-others speak English or are Muslim or worship spirits. Under apartheid, being Coloured became something to try to escape from. Many tried to pass as white; some succeeded in getting "reclassified". Aspiring to whiteness and fearful of blackness, their identity is hesitant, even defensive. Many Coloureds feel most sure about what they are not: they vigorously resist any attempt to use the term "black" to embrace all nonwhite people. "My people are terrible racists, but not by choice," says Joe Marks, a Coloured member of the Western Cape parliament. "The blacks today have the political power, the whites have economic power. We just have anger./

单选题He won by ______ because his opponent refused to play.

单选题On the morning of September 11th, I boarded the train from Washington Heights in Upper Manhattan just as usual and went to the Body Positive office in the South Street Seaport of Lower Manhattan. While I was leaving the subway at 8:53 am, a man ran down the street screaming, "Someone just bombed the World Trade Center." Those around me screamed and shouted "No!" in disbelief. However, being an amateur photographer, and thinking that I might be able to help out, I ran directly toward the WTC. I stopped just short of the WTC at a comer and looked up. There before me stood the gaping hole and fire that had taken over the first building. I stood there in shock taking pictures, wanting to run even closer to help out, but I could not move. Soon I saw what looked like little angels floating down from the top of the building. I began to cry when I realized that these " angels" —in fact, desperate office workers--were coming down, some one-by-one, some even holding hands with another. Could I actually be seeing this disaster unfold with hundreds of people around me crying, screaming and running for safety? As I watched in horror, another white airliner came from the south and took aim at the South Tower. As the plane entered the building, there was an explosion and fire and soon debris (碎片) began to fall around me. It was then that I realized that we were being attacked and that this was just not a terrible accident. Yet, I still could not move, until I was pushed down by the crowd on the street, many now in a panic running toward the water, as far from the WTC as they could possibly get. All around me were the visual reminders of hundreds of people running in panic. There were shoes, hats, briefcases, pocketbooks, newspapers, and other personal items dropped as hundreds of people ran for safety. Much has been written about the disaster already. We have learned so much in such a small amount of time about appreciating life. In some way we must move forward, bury the dead, build a memorial for those lost, and begin the coping and healing process for the survivors. But healing takes time. Some have been able to head right back to work, others seek counseling, while others remain, walking through the streets with expressionless faces. However, we are all united in our grief.

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.
