单选题{{B}}Passage Three{{/B}} Our culture has caused most Americans to assume not only that our language is universal but that the gestures we use are understood by everyone. We do not realize that waving good-bye is the way to summon a person from the Philippines to one's side, or that in Italy and some Latin-American countries, curling the finger to oneself is a sign of farewell. Those private citizens who sent packages to our troops occupying Germany after World War Ⅱ and marked the items GIFT to escape duty payments did not bother to find out that "gift" means poison in German. Moreover, we like to think of ourselves as friendly, yet we prefer to be at least 3 feet or an arm's length away from others. Latins and Middle Easterners like to come closer and touch, which makes Americans uncomfortable. Our linguistic (语言上的) and cultural blindness and the casualness with which we take notice of the developed tastes, gestures, customs and languages of other countries, are losing us friends, business and respect in the world. Even here in the United States, we make few concessions to the needs of foreign visitors. There are no information signs in four languages on our public buildings or monuments; we do not have multilingual (多语的) guided tours. Very few restaurant menus have translations, and multilingual waiters, bank clerks and policemen are rare. Our transportation systems have maps in English only and often we ourselves have difficulty understanding them. When we go abroad, we tend to cluster in hotels and restaurants where English is spoken. The attitudes and information we pick up are conditioned by those natives-usually the richer --who speak English. Our business deals, as well as the nation's diplomacy, are conducted through interpreters. For many years, America and Americans could get by with cultural blindness and linguistic ignorance. After all, America was the most powerful country of the free world, the distributor of needed funds and goods. But all that is past. American dollars no longer buy all good things, and we are slowly beginning to realize that our proper role in the world is changing. A 1979 Harris poll reported that 55 percent of Americans want this country to play a more significant role in world affairs , we want to have a hand in the important decisions of the next century, even though it may not always be the upper hand.

单选题When the heart breaks down, it beats irregularly or not at all. A bone can chip or snap. But when the complex network of neurons in our brain malfunctions, the result can be a near-endless variety and combinations of mental illnesses. It"s normal to sometimes be sad, happy, anxious, confused, forgetful or fearful, but when a person"s emotions, thoughts or behavior frequently trouble them, or disrupt their lives, they may be suffering from mental illness. According to the World Health Organization (WHO), about 450 million people worldwide are affected by mental, neurological or behavioral problems at any time. Among the best known and most common mental illnesses is depression—a prolonged, debilitating sadness, sometimes accompanied by a feeling of hopelessness and thoughts of suicide. Seasonal affective disorder is a type of depression that affects some people in the autumn and winter and is triggered by the shrinking hours of daylight and colder temperatures. Personality disorders are behaviour patterns that are destructive to the person themselves or those around them. In dissociative disorders, someone experiences a sudden change in consciousness or their concept of self. In dissociative amnesia (遗忘症), for example, the result is a loss of part or all of their memories. Anxiety disorders are characterized by powerful feelings of stress and physical signs of fear—sweating, a racing heart—due to some cue in the environment, or for no obvious reason at all. Madness has long been linked with genius. Many famous artists, writers and scientists have suffered from mental disorders, leading some to wonder if there is a link between these illnesses and creativity. The mathematician John Nash struggled with schizophrenia while he developed the theory that earned him a Nobel Prize. The artist Vincent Van Gogh, the composer Robert Schumann and the writer Fyodor Dostoevsky are said to have suffered from a range of mental disorders including hypergraphia, a compulsion to write—a sign perhaps their art emerged from an unrelenting urge to communicate. One possibility is that genes that predispose people to such devastating illnesses persist because when the syndromes are present in a milder form, this heightened creativity gives people an evolutionary advantage.

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.
