单选题{{B}}Passage Three{{/B}} Musicians are fascinated with the possibility that music may be found in nature; it makes our own desire for art seem all the more essential. Over the past few years no less a bold musical explorer than Peter Gabriel has been getting involved. At the Research Center in Atlanta, Georgia, he has been making music together with Kanzi, one of the bonobo apes (倭黑猩猩) involved in the long-term language acquisition studies of Sue and Duane Savage-Rumbaugh. I have seen the video of Kanzi picking notes out on a piano-like keyboard, with Gabriel and members of his band playing inside the observation booth in the lab. (They did it this way because Kanzi had bitten one of his trainers a few days previously—interspecies communication is not without its dangers. ) The scene is beautiful, the ape trying out the new machine and looking thoughtfully pleased with what comes out. He appears to be listening, playing the right notes. It is tentative but moving, the animal groping for something from the human world but remaining isolated from the rest of the band. It is a touching encounter, and a bold move for a musician whose tune Shock the Monkey many years ago openly condemned the horrors of less sensitive animal experiments than this. What is the scientific value of such a jam session? The business of the Research Center is the forging of greater communication between human and animal. Why not try the fertile and mysterious ground of music in addition to the more testable arena of simple language? The advantage of hearing music in nature and trying to reach out to nature through music is that, though we don't fully understand it, we can easily have access to it. We don't need to explain its workings to be touched by it. Two musicians who don't speak the same language can play together, and we can appreciate the music from human cultures far from our own. Music needs no explanation, but it clearly expresses something deep and important, something humans cannot live without. Finding music in the sounds of birds, whales and other animals makes the farther frontiers of nature seem that much closer to us.

单选题{{B}}Passage Three{{/B}} In recent years there has been an increasing number of large oil spills. These spills, some of which have occurred directly at the site of extraction and others during transportation, have had in adverse effect on marine organisms. Because of the importance of these organisms in the life cycle, research has been carried out in order to identify more accurately the reactions of these organisms to oil. A recent study has revealed that it is essential to understand that there is not one but rather, at least four possible ways in which oil can affect an organism. First, as a result of an organism's ingestion of oil, direct lethal toxicity (毒性), that is, death by poisoning, can occur. However, in cases where the effect is less extreme, sub-lethal toxicity occurs. While cellular and physiological processes are involved in both cases in the latter, the organism continues to survive. Second, in some cases, oil forms a covering on the organism. This covering, referred to as coating, can result in smothering, that is, death of the organism due to lack of air. In instances where the effects of coating are less severe, interference with movement and loss of insulated properties of feathers or fur may occur. The third effect of oil on marine organisms is the tainting or contamination of edible organisms. This results from the incorporation of hydrocarbons (碳化氢) into the organism, thus making it unfit for human consumption. The final effect which this study has revealed is that of habitual changes. The alterations in the physical and chemical environment brought about by oil spills result in a change in the species composition of a region. The implications of this must recent study are far-reaching. An oil spill in a particular region could critically upset the balance of nature, the total effect only becoming apparent after many years.

单选题{{B}}Passage Four{{/B}} Can an inventive society get bolder as it grows older? That question affects people of all ages—especially those living in the United States, Europe, and Japan, which are expected to have fewer workers supporting more retirees. According to Science and Engineering Indicators (SEI):2OO2,issued by the National Science Board (NSB),America's science and engineering workforce will continue to grow in coming decades, but its average age is likely to rise. Will scientific workers in their 50s and 60s continue to make valuable contributions? The report avoided asking whether aging impairs creativity. If it does, then the growth of our productivity and improvement of our standard of living might be in trouble. There is already a shortage of young Americans in research; in 2003 the NSB expressed concern over the United States' dependence on foreign PhDs. Scientists, often older ones, have for years questioned how long they can stay productive. G.H. Hardy set the tone in his 1940 classic, A Mathematician's Apology. "Like any other mathematician who has passed sixty," Hardy confessed, "I have no longer the freshness of mind, the energy, or the patience to carry on effectively with my proper job." He continued that "mathematics... is a young man's game." The age lore of other sciences can be similarly misleading. The Nobel laureate physicist Paul Dirac has suggested, tongue in cheek, that a physicist over 30 was as good as dead, and the physicist-historian Abraham Pals wrote of Einstein after 1925 (when Einstein was 46)that, as far as his work went, he might as well have gone fishing. And yet the sociologist Harriet Zuckerman, in her landmark 1977 book, Scientific Elite ,observed that U.S. Nobelists received their prizes for work done when they were, on average, nearly 39. Sir Nevill Mott won a Nobel Prize in physics for his postretirement research. Great biologists seem especially hardy. The German naturalist Alexander von Humboldt successfully surveyed harsh, remote areas of the Russian Empire for goldfields after turning 60,and began publishing the 19th century's greatest work of synthesis, Cosmos, at age 76;he had completed 2000 pages by his death at 89,in 1859. More recently, Harvard University's Ernst Mayr was still writing papers at 100. Why, then, do certain researchers stagnate while others flourish? Some might be internalizing what Zuckerman called the "mythology" of aging in science. But another factor is that any education has built-in limits. Even Einstein may have been bumping against them. Scientists over 40 face a choice: continue using the endowments that have served them well but are challenged by a new generation, or turn to new subjects.

单选题About four years ago, Kerry Sturgill found herself at a career crossroads: Should she stay in an industry populated by extroverts(外向型的人) or jump ship to a more reflective place where introverts like her were in the majority? Career counselors had told her to get out of the highly extroverted public relations fields " so you can be happy and do what you are. " Among the less fast-paced areas they pointed to: art, scientific research, data analysis. Such a move is definitely the right road for many introverts struggling to fit into an extroverted workplace. So, just what is an introvert anyway? It's someone who is energized by thought and reflection, while extroverts are energized by socializing. Introverts naturally need to think before they speak. Extroverts use the speaking process to figure out what it is they want to say. And, needless to say, there are pluses and minuses to both personality types. Still, in the modern world where as many as two-thirds of the population may be extroverted, those who are the opposite can be misunderstood. They can be seen as antisocial, secretive, even territorial, because they can sometimes try to protect their "space" and quiet. Workplaces can actually benefit from having both types, says Deborah Barrett, program director of the Rice University MBA communications program. An introvert herself, she says she has the best of both worlds—working in an environment of professors, who tend towards introversion, yet getting to teach, which calls on her more "out there" skills. Here's her advice for those looking to follow the same path: Make good use of e-mail. If you don't get to make a point at a loud meeting, send a follow-up email sharing your thoughts. If you don't have an office and are easily distracted by ongoing small talk, consider listening to music through headphones. But take care not to make your more sociable neighbors feel rejected. Sure, she says, if she had moved to a less stimulating environment, that might have "short- circuited a lot of nay pain, but I also believe it would have short-circuited learning what's made me a much more well-rounded person." Her main lesson?" I don't have to be an extrovert. I just have to play at being one for an hour. /

单选题Attacking an increasingly popular Internet business practice, a consumer watchdog group Monday filed a complaint with the Federal Trade Commission, asserting that many online search engines are concealing the impact special fees have on search results by Internet users. Commercial Alert, a 3-year-old group founded by consumer activist Ralph Nader, asked the FTC to investigate whether eight of the Web's largest search engines are violating federal laws against deceptive advertising. The group said that the search engines are abandoning objective formulas to determine the order of their listed results and selling the top spots to the highest bidders without making adequate disclosures to Web surfers. The complaint touches a hot-button issue affecting tens of millions of people who submit search queries each day. With more than 2 billion pages and more than 14 billion hyperlinks on the Web, search requests rank as the second most popular online activity after E-mail. The eight search engines named in Commercial Alert's complaint are: MSN, owned by Microsoft; Netscape, owned by AOL Time Warner; Directhit, owned by Ask Jeeves; HotBot and Lycos, both owned by Term Lycos; Altavista, owned by CMGI; LookSmart, owned by LookSmart; and iWon, owned by a privately held company operating under the same name. Portland, Ore.-based Commercial Alert could have named more search engines in its complaint, but focused on the biggest sites that are auctioning off spots in their results, said Gary Ruskin, the group's executive director. "Search engines have become central in the quest for learning and knowledge in our society. The ability to skew (扭曲) the results in favor of hucksters (小贩) without telling consumers is a serious problem. " Ruskin said. By late Monday afternoon, three of the search engines had responded to The Associated Press' inquiries about the complaint. Two, LookSmart and AltaVista, denied the charges. Microsoft spokesman Matt Pilla said MSN is delivering "compelling search results that people want". The FTC had no comment about the complaint Monday. The complaint takes aim at the new business plans embraced by more search engines as they try to cash in on their pivotal (关键) role as Web guides and reverse a steady stream of losses. To boost revenue, search engines in the past year have been accepting payments from businesses interested in receiving a higher ranking in certain categories or ensuring that their sites are reviewed more frequently.
