单选题Ever since the 1750s, when the writer, satirist, statesman and inventor Benjamin Franklin put political cartooning on the map by publishing the first cartoon of the genre in America, artists have combined their talent, wit and political beliefs to create cartoons that enrage, enlighten or simply engage the viewer. A picture may paint a thousand words, but a cartoon provokes, protests and entertains all at once. It is this that makes cartoonists so valuable and influential in times of crisis. Today, that crisis is climate change, and clever imagery can give new impetus to our struggle to combat global warming. The organizers of Earthworks 2008, a global cartoon competition, believe that art and humor are simple ways to get the environmental message across. "We set up the competition to give cartoonists around the world a platform on which to express themselves," says John Renard, one of the Earthworks organizers. "We hoped the competition would stimulate cartoonists to use their pens and wit to help combat environmental devastation and give new impetus to our desperate fight to stop global warming," he says. "After all, humor is often a valuable key in the struggle to win hearts and minds." But despite the sharp wit that pervades the cartoons, climate change is no laughing matter for their creators. The 50 or so countries from which the 600 competition entries were sent are all suffering the effects of global warming, some more dramatically than others. Two cartoons were sent from Burma, where in May this year a tropical storm tore through five regions along the western coast, killing at least 100,000 people, and leaving millions more without shelter, food, or clean water. Although governments around the world are reluctant to suggest, officially, that the disaster in Burma is a direct result of global warming, there"s little doubt that it will have added to the tropical storm"s destructive power. Studies published in the journals Nature and Science have demonstrated a link between rising sea temperatures and increased wind-speed of tropical storms and hurricanes, and even US-government-funded organizations such as the National Oceanic and Atmospheric Administration admit that a warming of the global climate will affect the severity of storms. "Experiencing first-hand the catastrophic effects of climate change allowed these artists to give their cartoons a special sharpness," says Revent.

单选题To broaden their voting appeal in the presidential election of 1796, the Federalists selected Thomas Pinckney, a leading South Carolinian, as framing mate for the New Englander John Adams. But Pinckney' s Southern friends chose to ignore their party' s intentions and regarded Pinckney as a presidential candidate, creating a political situation that Alexander Hamilton was determined to exploit. Hamilton had long been wary of Adams' stubbornly independent brand of politics and preferred to see his running mate, over whom he could exert more control, in the President's chair. The election was held under the system originally established by the Constitution. At that time there was but a single tally, with the candidate receiving the largest number of electoral votes declared President and the candidate with the second largest number declared Vice-President. Hamilton anticipated that all the Federalists in the North would vote for Adams and Pinckney equally in an attempt to ensure that Jefferson would not be either first or second in the voting. Pinckney would be solidly supported in the south while Adams, yet both Federalists would outpoll Jefferson. Various methods were used to persuade the electors to vote as Hamilton wished. In the press, anonymous articles were published attacking Adams for his monarchial tendencies and Jefferson for being overly democratic, while pushing Pinckney as the only suitable candidate. In private correspondence with state party leaders the Hamiltonians encouraged the idea that Adams' popularity was slipping, that he could not win the election, and that the Federalists could defeat Jefferson only by supporting Pinckney. Had sectional pride and loyalty not run as high in New England as in the deep south, Pinckney might well have become Washington' s successor. New Englanders, however, realized that equal votes for Adams and Pinckney in their states would defeat Adams, therefore, eighteen electors scratched Pinckney' s name from their ballots and deliberately threw away their second votes to men who were not even running. It was fortunate for Adams that they did, for the electors from South Carolina completely abandoned him, giving eight votes to Pinckney and eight to Jefferson. In the end, Hamilton' s interference in Pinckney' s candidacy lost even the Vice-Presidency of South Carolina. Without New England' s support, Pinckney received only 59 electoral votes, finishing third to Adams and Jefferson. He might have been President in 1979, or as Vice-President a serious contender for the Presidency in 1800; instead, stigmatized by a plot he had not devised, he set wed a brief term in the United States Statute and then dropped from sight as a national influence.

单选题Observe the dilemma of the fungus: it is a plant, but it possesses no chlorophyl. While all other plants put the sun's energy to work for them combining the nutrients of ground and air into body structure, the chlorophylless fungus must look elsewhere for an energy supply. It finds it in those other plants which, having received their energy free from the sun, relinquish it at some point in their cycle either to other animals (like us humans) or to fungi. In this search for energy the fungus has become the earth's major source of rot and decay. Wherever you see mold forming on a piece of bread, or a pile of leaves turning to compost, or a blown-down tree becoming pulp on the ground, you are watching a fungus eating. Without fungus action the earth would be piled high with the dead plant life of past centuries. In fact, certain plants which contain resins that are toxic to fungi will last indefinitely. Specimens of the redwood, for instance, can still be found resting on the forest floor centuries after having been blown down.

单选题War has escaped the battlefield and now can, with modern guidance systems on missiles, touch virtually every square yard of the earth's surface. War has also lost most of its utility in achieving the traditional goals of conflict. Control of territory carries with it the obligation to provide subject peoples certain administrative, health, education, and other social services. Such obligations far outweigh the benefits of control. If the ruled population is ethnically or racially different from the rulers, tensions and chronic unrest often exist which further reduce the benefits and increase the costs of domination. Large populations no longer necessarily enhance state power and, in the absence of high levels of economic development, can impose severe burdens on food supply, jobs, and the broad range of services expected of modern governments. The noneconomic security reasons for the control of territory have been progressively undermined by the advances of modern technology. The benefits of forcing another nation to surrender its wealth are vastly outweighed by the benefits of persuading that nation to produce and exchange goods and services. In brief, imperialism no longer pays. Making war has been one of the most persistent of human activities in the 80 centuries since men and women settled in cities and thereby became "civilized", but the modernization of the past 80 years has fundamentally changed the role and function of war. In premodernized societies, successful warfare brought significant material rewards, the most obvious of which were the stored wealth of the defeated. Equally important was human labor--control over people as slaves or levies for the victor's army, and there was the productive capacity--agricultural lands and mines. Successful warfare also produced psychic benefits. The removal or destruction of a threat brought a sense of security, and power gained over others created pride and national self-esteem. War was accepted in the premodernized society as a part of the human condition, a mechanism of change, and an unavoidable, even noble, aspect of life. The excitement and drama of war made it a vital part of literature and legends.

单选题 The planet's wild creatures face a new threat—from yuppies (雅皮士), empty nesters and one parent families. Biologists studying the pressure on the planet's dwindling biodiversity today report on a new reason for alarm. Although the rate of growth in the human population is decreasing, the number of individual households is exploding. Even where populations have actually dwindled in some regions of New Zealand, for instance—the numbers of individual households has increased, because of divorce, career choice, smaller families and longer lifespan. Jianguo Liu of Michigan State University and colleagues from Stanford University in California report in Nature, in a paper published online in advance, that a greater number of individual households, each containing on average fewer people, meant more pressure on natural resources. Towns and cities began to sprawl as new homes were built. Each household needed fuel to heat and light it; each household required its own plumbing, cooking and refrigeration. 'In larger households, the efficiency of resource consumption will be a lot higher, because more people share things,' Dr Liu said. He and his colleagues looked at the population patterns of life in 141 countries, including 76 'hotspot' regions unusually rich in a variety of local wildlife. These hotspots included Australia, New Zealand, the US, Brazil, China, India, Kenya, and Italy. They found that between 1985 and 2000 in the 'hotspot' parts of the globe, the annual 3.1% growth rate in the number of households was far higher than the population growth rate of 1.8%. 'Had the average household size remained at the 1985 level,' the scientists report, 'there would have been 155 million fewer households in hotspot countries in 2000. Dr Liu's work grew from the alarming discovery that the giant pandas living in China's Wolong reserve are more at risk now than they were when the reserve was first established. The local population had grown, but the total number of homes had increased more swiftly, to make greater inroads into the bamboo forests. Only around 1.75 million species on the planet have been named and described. Biologists estimate that there could be 7 million, or even 17 million, as yet to be identified. But human numbers have grown more than sixfold in the past 200 years, and humans and their livestock are now the greatest single consumer group on the planet. The world population will continue to soar, perhaps leveling off around 9 billion in the next century. Environmental campaigners have claimed that between a quarter and a half of all the species on earth could become extinct in the next century.

单选题Pronouncing a language is a skill. Every normal person is an expert in the skill of pronouncing his own language, but few people are even moderately proficient at pronouncing foreign languages. Now there are many reasons for this. Some are obvious, some perhaps not so obvious. But I suggest that the fundamental reason why people in general do not speak foreign languages much better than they do in their own languages is that they fail to grasp the true nature of the problem of learning to pronounce them, and consequently never set about speaking them in the right way. Far too many people fail to realize that pronouncing a foreign language is a skill that needs careful training of a special kind, and one that cannot be acquired by just leaving it to take care of itself. I think even teachers of language, while recognizing the importance of a good accent, tend to neglect, in their practical teaching, the branch of study concerned with speaking the language. So the first point I want to make is that English pronunciation must be taught, the teacher should be prepared to devote some of the lessons to this, and his whole attitude to the subject should make the students feel that here is a matter worthy of receiving their close attention.
