Within a year, consumers had returned millions of aluminum cans and glass and plastic bottles. Plenty of companies were eager to accept the aluminum and glass as raw materials for new products, but because few could figure out what to do with the plastic, much of it wound up buried in landfills(垃圾填埋场). The problem was not limited to New York. Unfortunately, there were too few uses for second-hand plastic. Today, one out of five plastic soda bottles is recycled(回收利用) in the United States. The reason for the change is that now there are dozens of companies across the country buying discarded plastic soda bottles and turning them into fence posts, paint brushes, etc. As the New York experience shows, recycling involves more than simply separating valuable materials from the rest of the rubbish. A discard remains a discard until somebody figures out how to give it a second fife—and until economic arrangements exist to give that second life value. Without adequate markets to absorb materials collected for recycling, throwaways actually depress prices for used materials. Shrinking landfill space, and rising costs for burying and burning rubbish are forcing local governments to look more closely at recycling. In many areas, the East Coast especially, recycling is already the least expensive waste-man-agement option. For every ton of waste recycled, a city avoids paying for its disposal, which, in parts of New York, amounts to savings of more than $100 per ton. Recycling also stimulates the local economy by creating jobs and trims the pollution control and energy costs of industries that make recycled products by giving them a more refined raw material.

单选题 Symbolic Process The process by means of which human beings arbitrarily make certain things stand for other things many be called the symbolic process. Everywhere we turn, we see the symbolic process at work. There are {{U}} {{U}} 1 {{/U}} {{/U}}things men do or want to do, possess or want to possess, that have not a symbolic value. Almost all fashionable clothes are {{U}} {{U}} 2 {{/U}} {{/U}}symbolic, so is food. We {{U}} {{U}} 3 {{/U}} {{/U}}our furniture to serve {{U}} {{U}} 4 {{/U}} {{/U}}visible symbols of our taste, wealth, and social position. We often choose our houses {{U}} {{U}} 5 {{/U}} {{/U}}the basis of a feeling that it "looks well" to have a "good address." We trade perfectly good cars in for {{U}} {{U}} 6 {{/U}} {{/U}}models not always to get better transportation, but to give {{U}} {{U}} 7 {{/U}} {{/U}}to the community that we can {{U}} {{U}} 8 {{/U}} {{/U}}it. Such complicated and apparently {{U}} {{U}} 9 {{/U}} {{/U}}behavior leads philosophers to ask over and over again, "why can't human beings {{U}} {{U}} 10 {{/U}} {{/U}}simply and naturally." Often the complexity of human life makes us look enviously at the relative {{U}} {{U}} 11 {{/U}} {{/U}}of such live as dogs and cats. Simply, the fact that symbolic process makes complexity possible is no {{U}} {{U}} 12 {{/U}} {{/U}}for wanting to {{U}} {{U}} 13 {{/U}} {{/U}}to a cat and to a cat-and-dog existence. A better solution is to understand the symbolic process {{U}} {{U}} 14 {{/U}} {{/U}}instead of being its slaves we become, to some degree at least, its {{U}} {{U}} 15 {{/U}} {{/U}}

单选题{{B}}第二篇{{/B}} {{B}} Superconducting Ceramic (陶瓷){{/B}} An underground revolution begins this winter. With the flip (轻击) of a switch, 30,000 homes in one part of Detroit will soon become the first in the country to receive electricity transmitted by ice-cold high-performance cables. Other American cities are expected to follow Detroit's example in the years ahead, which could conserve enormous amounts of power. The new electrical cables at the Frisbie power station in Detroit are revolutionary because they are made of superconductors. A superconductor is a material that transmits electricity with little or no resistance. Resistance is the degree to which a substance resists electric current. All common electrical conductors have a certain amount of electrical resistance. They convert at least some of the electrical energy passing through them into waste heat. Superconductors don't. No one understands how superconductivity works. It just does. Making superconductors isn't easy. A superconducting material has to be cooled to an extremely low temperature to lose its resistance. The first superconductors, made more than 50 years ago, had to be cooled to -263 degrees Celsius before they lost their resistance. Newer superconducting materials lose their resistance at -143 degrees Celsius. The superconductors cable installed at the Frisbie station is made of a ceramic material that contains copper, oxygen, bismuth (铋), strontium (锶), and calcium (钙). A ceramic is a hard, strong compound made from clay or minerals. The superconducting ceramic has been fashioned into a tape that is wrapped lengthwise around a long tube filled with liquid nitrogen. Liquid nitrogen is supercold and lowers the temperature of the ceramic tape to the point where it conveys electricity with zero resistance. The United States loses an enormous amount of electricity each year to resistance. Because cooled superconductors have no resistance, they waste much less power. Other cities are watching the Frisbie experiment in the hope that they might switch to superconducting cable and conserve power, too.

Before the {{U}}(51) {{/U}}of modern trains, camel trains used to carry al! the goods for trading between Central Africa and Europe. Traders sometimes{{U}} (52) {{/U}}to put together camel trains with 10,000 to 15,000 animals. Each animal often carried{{U}} (53) {{/U}}400 pounds and it could travel twenty miles a day. This form of transportation was so important{{U}} (54) {{/U}}camels were called the "ship of the desert". Now modern trains travel across the desert in a very{{U}} (55) {{/U}}time. One engine can pull as much weight as 135,000{{U}} (56) {{/U}},in addition, trains use special cars for their load. Refrigerator cars carry food; boxcars carry heavy goods; stock cars carry animals; and tank cars carry oil. {{U}} (57) {{/U}}travel has changed, too. The earliest planes were biplanes, with two sets of wings. The top speed of this plane was 60 miles per hour. The pilots used to sit or lie on the wings in the open air. The plane{{U}} (58) {{/U}}sometimes stopped in the middle of a trip. It used to be{{U}} (59) {{/U}} to fly in bad weather. In snow or in rain, the wings frequently became icy.{{U}} (60) {{/U}}the plane might go down. Mechanical improvements during the First World War changed airplanes. Monoplanes took the place of biplanes. Pilots flew inside of covered cabins. Still, even these planes were small and expensive. Only{{U}} (61) {{/U}}people were able to travel in airplanes. Now modern jets make air travel possible for all people.{{U}} (62) {{/U}}place in the world is more than 1 hours away by jet.

单选题Technology Transfer in Germany When it comes to translating basic research into industrial success, few nations can match Germany. Since the 1940s, the nation's vast industrial base has been fed with a constant stream of new ideas and expertise from science. And though German prosperity (繁荣) has faltered (衰退) over the past decade because of the huge cost of unifying east and west as well as the global economic decline, it still has an enviable record for turning ideas into profit. Much of the reason for that success is the Fraunhofer Society, a network of research institutes that exists solely to solve industrial problems and create sought-after technologies. But today the Fraunhofer institutes have competition. Universities are taking an ever larger role in technology transfer, and technology parks are springing up all over. These efforts are being complemented by the federal programmes for pumping money into start-up companies. Such a strategy may sound like a recipe for economic success, but it is not without its critics. These people worry that favouring applied research will mean neglecting basic science, eventually starving industry of fresh ideas. If every scientist starts thinking like an entrepreneur (企业家), the argument goes, then the traditional principles of university research being curiosity-driven, free and widely available will suffer. Others claim that many of the programmes to promote technology transfer are a waste of money because half the small businesses that are promoted are bound to go bankrupt within a few years. While this debate continues, new ideas flow at a steady rate from Germany's research networks, which bear famous names such as Helmholtz, Max Planck and Leibniz. Yet it is the fourth network, the Fraunhofer Society, that plays the greatest role in technology transfer. Founded in 1949, the Fraunhofer Society is now Europe's largest organisation for applied technology, and has 59 institutes employing 12,000 people. It continues to grow. Last year, it swallowed up the Heindch Hertz Institute for Communication Technology in Berlin. Today, there are even Fraunhofers in the US and Asia.

Technology{{U}} (51) {{/U}}tactics, sociology, and the development of weaponry (武器). It also causes the changes in battles. Then what are the new characteristics of modern battles{{U}} (52) {{/U}}by the application of high technologies? High-tech warfare naturally includes high technology. In modern battles, a single kind of weapon can hardly be{{U}} (53) {{/U}}. Various weaponry, such as intelligence detection and information processing, should{{U}} (54) {{/U}}well with each other. Aerial (航空的) weaponry becomes the main force in battles in the sky. Precision homing (精确自导) weaponry like cruise missiles and Missiles{{U}} (55) {{/U}}satellite homing systems becomes the main attack weapons. Battle control systems play a dominant role. Various weapons and logistics (后勤) systems are{{U}} (56) {{/U}}into a comprehensive framework, centrally representing the modern high-tech weaponry. Depending on various{{U}} (57) {{/U}}equipment and means in electronic warfare, our army will not be passively beaten.{{U}} (58) {{/U}}the battlefield, high-tech warfare has created a type of non-linear (非线性的) chaos. Because of the use of long-range precision weaponry, the opposite parties in warfare can't "touch" or "see" each other, and distance is no longer the decisive factor affecting the{{U}} (59) {{/U}}of battles. It is hard to clearly define the lines between the frontier and the rear, as well as attack and defense. The traditional three-dimensional air-sea battlefield will be{{U}} (60) {{/U}}by the multi-dimensional battlefield composed of air, sea, magnetic, electrical and information battlefields. No large-scale movements can be conducted{{U}} (61) {{/U}}. Because modern weaponry systems are closely related to chains of demand and communication and electronic technology, the parties{{U}} (62) {{/U}}have to pay attention to the usufruct (使用权) and control of electromagnetic frequency spectrum. So electronic warfare becomes{{U}} (63) {{/U}}important and the necessary guarantee of victory. Whatever{{U}} (64) {{/U}}warfare goes to and whatever cloak (伪装) it wears, it always violates peace and brings the world bloodshed (流血). Most people think of high technology as a{{U}} (65) {{/U}}to enhance their lives, and they don't wish it to be used to destroy lives.

单选题Obesity Causes Global Warming The list of ills attributable to obesity keeps growing: Last week, obese people were accused of causing global warming. This conclusion comes from Sheldon Jacobson of the University of Illinois, U. S. , and a doctoral student, Laura McLay. Their study calculates how much extra gasoline is needed to haul fat Americans around. The answer, they say, is a billion gallons of gas per year. It means an extra 11 million tons of carbon dioxide. There has been calls for taxes on junk food in recent years. U. S. economist Martin Schmidt suggests a tax on fast food delivered to people's cars. "We tax cigarettes partly because of their health cost," Schmidt said. "Similarly, leading a lazy lifestyle will end up costing taxpayers more. " U. S. political scientist Eric Oliver said his first instinct was to laugh at these gas and fast food arguments. But such claims are getting attention. At the U. S. Obesity Society's annual meeting, one person correlated obesity with car accident deaths, and another correlated obesity with suicides. No one asked whether there was really a cause-and-effect relationship. "The funny thing was that everyone took it seriously," Oliver said. In a 1960s study, children were shown drawings of children with disabilities and without them, a drawing of an obese child. They were asked which they would want for a friend? The obese child was picked last. Three researchers recently repeated the study using college students. Once again, ahnost no one, not even obese people, liked the obese person. "Obesity was stigmatized," the researchers said. But, researchers say, getting thin is not like quitting smoking. People struggle to stop smoking, and, in the end, many succeed. Obesity is different. But, not because obese people don't care. Science has shown that they have limited personal control over their weight.
