单选题The questions in this group are based on the content of a passage. After reading the passage, choose the best answer to each question. Answer all questions following the passage on the basis of what is stated or implied in the passage. Congressman Hastings has proposed that Congress should abolish the Electoral College system for electing the president and replace it with a system of direct popular election. The Electoral College system is flawed, he argues, because it runs directly counter to the democratic principle that every citizen's vote should count equally. Because of the winner-take-all system in which the candidate who receives the most popular votes in a state receives all of that state's electoral votes, the citizens who voted for the losing candidate are effectively disenfranchised from the national election, even if their candidate lost the state by only a handful of votes. Moreover, because each state's number of electors is the same as its number of members of Congress, the citizens of small states get a disproportionately larger vote than citizens of more populous states. In the 1988 election, for example, the combined voting-age population of the six least populous states--Alaska, Delaware, North Dakota, South Dakota, Vermont, and Wyoming--was 3,119,000. These six states held 21 electoral votes among them. Florida, with a voting-age population of 9,614,000, also had 21 electoral votes. Because of inequities of this nature, there have been four presidential elections in which the candidate who won the Electoral College actually lost the popular vote: 1824, 1876, 1888, and 2000. Congressman Markham has argued that Hastings's proposed changes are unnecessary and even dangerous. First of all, he argues, the Electoral College system, whatever its flaws, has resulted in a stable democratic government for more than 200 years, which shows that it is doing something right. Second, the winner-take-all system helps create decisive majorities in the Electoral College, thereby reducing the problem of disputed elections that we might see in the event of direct popular elections. Third, the current system of allocating electors helps protect the interests of small states, which would be largely neglected in favor of large states if the Electoral College were based entirely on population. Protecting these states' rights is essential to upholding the principle of federalism (in which the states and the federal government maintain distinct powers). When the Electoral College system was first formalized by the Twelfth Amendment in 1804, a direct popular vote would have been impossible to implement, and the Electoral College was probably the best way to approximate the will of the people. Advances in technology and communication, however, now mean that a direct popular vote would be as simple, if not simpler, to administer than the current Electoral College system. Alternative ways to reform the system would be to do away with the winner-take-all system of state electors, to base the numbers of electors strictly on state populations, or to have a direct popular election but to weight the votes from different states differently in order to preserve the influence of small states.

单选题{{B}}B{{/B}} Crocodiles only live where it is hot. They are found in India, Australia, Africa and America. The crocodile is an egg-producing animal. They spend most of their time lying around in the mud or the rivers. The female crocodiles bury their eggs under the mud. The crocodile's long powerful tail is used when the animal is swimming. It is also an excellent weapon, because it can be swung with great speed and force. One blow will knock down a man or even a big animal at once. The crocodile is very well protected against its enemies by the hard bony plates that cover most of its body, but because of the way its neck is formed, it can not turn its head from side to side and so it can only see in front of itself. The crocodile has its teeth cleaned by another crocodile, which can't clean its own teeth for it can't move its tongue up and down. With its rows of terrible points of teeth it seizes its food, which may be a fish, an animal or even a careless man, and then holds it below the water until it drown. The long-nosed crocodile is shy and timid and because of this, the people of West Africa sometimes catch it for food. Many, many centuries ago, there were crocodiles in England. We know this because we have found their bones buried far down in the earth on which London is built. But the Britain of today is too cold for them to live in.

单选题Animals other than humans have not developed communications comparable to human language. But is it possible that other animals have the【C21】______to learn a language if they are adequately taught? Obviously, this is a fascinating notion. The idea of communicating directly with another species has long been a part of human folklore and children's fantasies. But【C22】______a scientific level, the question of whether animals can learn a language is important primarily, because it【C23】______to the controversy between the cognitive and the learning approaches to language. If language is【C24】______on and is actually an outgrowth of the intellectual structure of the human mind, there is the strong supposition【C25】______only humans are capable of using language. Therefore, Noam Chomsky and other psycholinguists have argued that only humans can learn a language, 【C26】______most behaviorists feel that with sufficient patience it should be possible to teach an animal some sort of language. 【C27】______the two schools of thought clearly differ on this point, it is not really a crucial test of the two theories. If a chimpanzee can master a simple language all it would mean is that the chimp's intellectual capacity and brain structure are more【C28】______to ours than we thought. It would not necessarily imply that our intellectual structure is unimportant in our own mastery of language. Thus, teaching an animal language is an impressive demonstration of the power of learning techniques, but it is not evident that language is developed entirely through learning. On the other hand, the question of whether other animals can learn a language is fascinating 【C29】______its own right, aside from its value as a test of the two theories of language development. Accordingly, 【C30】______one's position on the theoretical dispute, we must consider training an animal to use language a dramatic accomplishment.

单选题It"s the part of the job that stock analyst Hiroshi Naya dislikes the most: phoning investor managers on a Saturday or Sunday when he"s working on a report and facing a deadline. In Japan, placing a work call to someone on the weekend "feels like entering someone"s house with your shoes on, " says Naya, chief analyst at Ichiyoshi Research Institute in Tokyo. So last year, Naya started asking his questions via messages on Facebook. While a telephone call seems intrusive, he says, a Facebook message "feels more relaxed. " Many Japanese have become fans of Mark Zuckerberg"s company in the past year. It"s taken a while: Even as Facebook took off in India, Indonesia, and other parts of Asia, it"s been a laggard in Japan since its local-language version debuted in 2008. The site faced cultural obstacles in a country where people historically haven"t been comfortable sharing personal information, or even their names, on the Internet. Homegrown rivals such as community website operator Mixi and online game portals such as DeNA allow their users to adopt pseudonyms . The Japanese are overcoming their shyness, though. In February, Facebook had 13.5 million unique users, up from 6 million a year earlier. That puts Facebook in the No. 1 position in Japan for the first time, ahead of Twitter and onetime leader Mixi. "Facebook didn"t have a lot of traction in Japan for the longest time, " says Arvind Rajan, Asia-Pacific managing director for Linkedln, which entered the Japanese market last October and hopes to emulate Face book"s recent success. " They really did turn the corner, " he says. Rajan attributes the change in attitude to the March 11, 2011, earthquake and tsunami . During the crisis and its aftermath, sites such as Facebook helped parents and children locate each other and allowed people post and find reliable information. " The real-name case has been answered, " says Rajan. "People are getting it now. " Japanese see Facebook as a powerful business tool. The real-name policy makes the site a good place to cultivate relationships with would-be partners. As more companies such as retailers Uniqlo and Muji turn to Facebook to reach Japanese consumers, the Silicon Valley company is benefiting from a viruous cycle, says Koki Shiraishi, an analyst in Tokyo with Daiwa Securities Capital Markets. " It"s a chicken-and-egg thing : If everyone starts using it, then more people start using it. " As a result of Facebook"s rise, investors have soured on some of its rivals : DeNA"s stock price has dropped 24 percent in the past year, and Mixi"s has fallen 38 percent. Growth at Twitter—which also entered Japan in 2008—has stagnated , and the San Francisco company has partnered with Mixi to do joint marketing. Twitter Japan country manager James Kondo says there"s no reason to worry. Japan"s social networking scene "is a developing thing, " he says. "We"re not in a flat market where everyone is competing for a share of a fixed pie. "

单选题Climatic conditions are delicately adjusted to the composition of the Earth's atmosphere. If there were a change in the atmosphere--for example, in the relative proportions of atmosphere gases--the climate would probably change also. A slight increase in water vapor, for instance, would increase the hem-retaining capacity of the atmosphere and would lead to a rise in global temperatures. In contrast, a large increase in water vapor would increase the thickness and extent of the cloud layer, reducing the mount of solar energy reaching the Earth' surface. The level of carbon dioxide, CO2 in the atmosphere has important effect on climatic change. Most of the Earth's incoming energy is short-wavelength radiation, which tends to pass through atmospheric CO2 easily. The Earth, however, reradiates much of the received energy as a long-wavelength radiation, Which CO2 absorbs and then remits toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by the Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430℃. If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2 concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the CO2 concentration would lead only to a reduction in global temperatures of 3℃. If, because of an increase in forest fires or volcanic activity, the CO2 content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relies on both the warmth and the availability of CO2, would probably increase. As a consequence, plants would use more and more CO2. Eventually CO2 levels would diminish and the climate, in turn, would become cooler. With reduced temperatures many plants would die; CO2 would thereby be returned to the atmosphere and gradually the temperatures would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2 present in the atmosphere, with regular temperature increase and decrease of a set magnitude. Some climatologists argue that the burning of fossil fuels has raised the level of CO2 in the atmosphere and has caused a global temperature rise of at least 1℃. But a supposed global temperature rise of 1℃ may in reality be only several regional temperature increase, restricted to areas where there are many meteorological stations and caused simply by shifts in the pattern of atmospheric circulation. Other areas, for example the Southern Hemisphere oceanic zone, may be experiencing an equivalent temperature decrease that is unrecognized because of the shortage of meteorological recording stations.
