单选题About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table. I couldn"t help overhearing parts of their conversation. At one point the woman asked: "So, how have you been?" And the boy—who could not have been more than seven or eight years old—replied. "Frankly, I"ve been feeling a little depressed lately. " This incident stuck in my mind because it confirmed my growing belief that children are changing. As far as I can remember, my friends and I didn"t find out we were "depressed" until we were in high school. The evidence of a change in children has increased steadily in recent years. Children don"t seem childlike anymore. Children speak more like adults, dress more like adults and behave more like adults than they used to. Whether this is good or bad is difficult to say, but it certainly is different. Childhood as it once was no longer exists, why? Human development is based not only on innate (天生的) biological states, but also on patterns of access to social knowledge. Movement from one social route to another usually involves learning the secrets of the new status. Children have always been taught adult secrets, but slowly and in stages: traditionally, we tell sixth graders things we keep hidden from fifth graders. In the last 30 years, however, a secret-revelation (揭示) machine has been installed in 98 percent of American homes. It is called television. Television passes information, and indiscriminately (不加区分地), to all viewers alike, be they children or adults. Unable to resist the temptation, many children turn their attention from printed texts to the less challenging, more vivid moving pictures. Communication through print, as a matter of fact, allows for a great deal of control over the social information to which children have access. Reading and writing involve a complex code of symbols that must be memorized and practices. Children must read simple books before they can read complex materials. (351 words)

Mark your choice on the Answer Sheet by drawing with a pencil a short bar across the corresponding letter in the brackets. {{B}}Passage One{{/B}} For the past several years, the Sunday newspaper supplement Parade has featured a column called "Ask Marilyn". People are invited query Marilyn vos Savant, who at age 10 had tested at a mental level of someone about 23 years old; that gave her an IQ of 228—the highest score ever recorded. IQ tests ask you to complete verbal and visual analogies, to envision paper after it has been folded and cut, and to deduce numerical sequences, among other similar tasks, so it is a hit confusing when vos Savant fields such queries from the aver age Joe (whose IQ is 100) as. What's the difference between love and fondness? Or what is the nature of luck and coincidence? It's not obvious how the capacity to visualize objects and to figure out numerical patterns suits one to answer questions that have eluded some of the best poets and philosophers. Clearly, intelligence encompasses more than a score on a test, Just what does it mean to be smart? How much of intelligence can be specified, and how much can we earn about it from neurology, genetics, computer and other fields? The defining term of intelligence in humans still seems to be the IQ score, even though IQ tests are not given as often as alley used to be. The test comes primrily in two forms: the Stanford-Binet Intelligence Scale and the Wechsler Intelligence Scales (both come in adult and children's version). Generally costing several hundred dollars, they are usually given only by psychologists, although variations of them populate book stores and the World Wide Web. Superhigh scores like vos Savant's are no longer possible, because scoring is now based on a statistical population distribution among age peers, Rather than simply dividing the mental age by the chronological age and multiplying by 100. Other standardized tests, such as the Scholastic Assessmen: Test (SAT)and the Graduate Record Exam (GRE),capture the main aspects of IQ tests. Such standardized tests may not assess all the important elements necessary to succeed in school and in life, argues Robert J. Sternberg. In his article "How Intelligent Is Intelligence Testing?", Sternberg notes that traditional tests best assess analytica and verbal skills but fail to measure creativity and practical knowl- edge, components also critical to problem solving and life success. Moreover IQ tests do not necessarily predict so well once populations or situations change. Research has found that IQ predicted leadership skills when the tests were given under low-stress conditions, but under high-stress conditions, IQ was negatively correlated with leadership—that is, it predicted the opposite. Anyone who has toiled through SAT will testify that test-taking skill also matters, whether it's knowing when to guess or what questions to skip.

单选题 One of the questions that is coming into focus as we face growing scarcity of resources of many kinds in the world is how to divide limited resources among countries. In the international development community, the conventional wisdom has been that the 2 billion people living in poor countries could never expect to reach the standard of living that most of us in North America enjoy, simply because the world does not contain enough iron ore, protein, petroleum, and so on. At the same time, we in the United States have continued to pursue super affluence as though there were no limits on how much we could consume. We make up 6 percent of the world's people; yet we consume one-third of the world's resources. As long as the resources we consumed each year came primarily from within our own boundaries, this was largely an internal matter. But as our resources come more and more from the outside world, "outsiders" are going to have some say over the rate at which and terms under which we consume. We will no longer be able to think in terms of "our" resources and "their" resources, but only of common resources. As Americans consuming such a disproportionate share of the world's resources, we have to question whether or not we can continue our pursuit of super affluence in a world of scarcity. We are now reaching the point where we must carefully examine' the presumed link between our level of well-being and the level of material goods consumed. If you have only one crust of bread and get another crust of bread, your well-being is greatly enhanced. But if you have a loaf of bread, then an additional crust of bread doesn't make that much difference. In the eyes of most of the world today, Americans have their loaf of bread and are asking for still more. People elsewhere are beginning to ask why. This is the question we're going to have to answer, whether we're trying to persuade countries to step up their exports of oil to us or trying to convince them that we ought to be permitted to maintain our share of the world fish catch. The prospect of a scarcity of, and competition for, the world's resources requires that we reexamine the way in which we relate to the rest of the world. It means we find ways of cutting back on resource consumption that is dependent on the resources and cooperation of other countries. We cannot expect people in these countries to concern themselves with our worsening energy and food shortages unless we demonstrate some concern for the hunger, illiteracy and disease that are diminishing life for them.

单选题 These days a green building means more than just the color of the paint. Green building can also refer to environmentally friendly houses, factories and offices. Buildings account for 65 percent of total U.S. electricity use. But green buildings can reduce energy and water use. Also, the buildings are often located near public transportation such as buses and subways, so that people can drive their cars less. That could be good for the environment, because cars use lots of natural resources such as gasoline, and give off pollution. Green buildings are often built on previously developed land, so that the buildings don't destroy forests or other wild habitats(栖息地). Marry Dettling is a project manager for a building that puts these ideas into action. The Solaire has been called the country's first green residential high-rise building. According to Dealing, "We've reduced our energy consumption by one-third and our water by 50 percent. " Not everyone is leaping to move into a green building, however. Some people think that features such a solar panels cost more money than more traditional energy sources. Despite this, Dettling hopes that green buildings will become common in the future. "It's going to be big," she said.

单选题Passage 9 One of the most pressing challenges that the United States--and indeed, the world--will face in the next few decades is how to alleviate the growing stress that human activities are placing on the environment. The consequences are just too great to ignore. Wildlife habitats are being degraded or disappearing altogether as new developments take up more land. Plant and animal species are becoming extinct at a greater rate now than at any time in Earth's history. As many as 30 percent of the world's fish stocks are overexploited. And the list goes on. Yet, there is reason to have hope for the future. Advances in computing power and molecular biology are among the tremendous increases in scientific capability that are helping researchers gain a better understanding of these problems. Recent developments in science and technology could provide the basis for some major, and timely actions that would improve our understanding of how human activities affect the environment. One priority for research is improving hydrological forecasting. It has been estimated that the world's water use could triple in the next two decades. Already, widespread water shortages have occurred in parts of China, India, North Africa, and the Arabian Peninsula. The need for water also is taking its toll on freshwater ecosystems in the United States. Only 2 percent of the nation's streams are considered in good condition, and close to 40 percent of native fish species are rare to extinct. Using a variety of new remote sensing tools, scientists can learn more about how precipitation affects water levels, how surface water is generated and transported, and how changes in the landscape affect water supplies. To prevent outbreaks of infectious diseases in plants, animals, and humans, more study is needed on how pathogens, parasites, and disease-carrying species--as well as humans and other species they infect--are affected by changes in the environment. The overuse of antibiotics both in humans and in farm animals has contributed to the growth of antibiotic-resistant microorganisms. Researchers can take advantage of new technologies in genetics and computing to better monitor and predict the effects that environmental changes might have on disease outbreaks. Humans have made alterations to Earth's surface--such as tropical deforestation, reduction of surface and ground water, and massive development--so dramatic that they approach the levels of transformation that occurred during glacial periods. Such alterations cause changes in local and regional climate, and will determine the future of agriculture. Recent advances in data collection and analysis should be used to document and better understand the causes and consequences of changes in land cover and use.
