单选题Henry Ford, the famous U.S. inventor and car manufacturer, once said, "The business of America is business." By this he meant that the U.S. way of life is based on the values of the business world. Few would argue with Ford's statement. A brief glimpse at a daffy newspaper vividly shows how much people in the United States think about business. For example, nearly every newspaper has a business section, in which the deals and projects, finances and management, stock prices and labor problems of corporations are reported daily. In addition, business news can appear in every other section. Most national news has an important financial aspect to it. Welfare, foreign aid, the federal budget, and the policies of the Federal Reserve Bank are all heavily affected by business. Moreover, business news appears in some of the unlikeliest places. The world of arts and entertainment is often referred to as "the entertainment industry" or "show business". The positive side of Henry Ford's statement can be seen in the prosperity that business has brought to U.S. life. One of the most important reasons so many people from all over the world come to live in the United States is the dream of a better job. Jobs are produced in abundance because the U.S. economic system is driven by competition. People believe that this system creates more wealth, more jobs, and a materially better way of life. The negative side of Henry Ford's statement, however, can be seen when the word business is taken to mean big business. And the term big business—referring to the biggest companies—is seen in opposition to labor. Throughout U.S. history working people have had to fight hard for higher wages, better working conditions, and the fight to form unions. Today, many of the old labor disputes are over, but there is still some employee anxiety. Downsizing—the driving away of thousands of workers to keep expenses low and profits high—createsfeelings of insecurity for many.

单选题{{B}}Passage One{{/B}} It's a classic mystery of the deep. Why does the hammerhead shark (双髻鲨)have the bizarrely shaped head from which it gets its name? There have been a variety of suggested explanations. Some simply say that the sharks use their heads to "hammer" and pin down their favourite food. More plausibly, others have speculated that the wide lobes(圆形突出部分)of the hammerhead allow it to have longer electrorecep-tots, the organs that all sharks use to detect the electric fields produced by nearby prey. This might allow hammerheads to sense subtler electric fields from more distant prey than their narrow-headed cousins. Now it turns out that the shark's head does indeed help it find and capture prey, but not in the way that zoologists expected. Stephen Kajlura and Kim Holland of the University of Hawaii at Manoa set out to test the conventional theory by tricking young sharks into chasing phantom (虚构的)prey. Using a system of wires on the bottom of a shallow pool, they set up electric fields that mimicked those created by the bottom-dwelling shrimp and fish that form the sharks' usual diet. Sure enough, hungry sharks abruptly turned towards an electric field when they detected it. But when the researchers measured the distance at which this happened they found it was the same for 13 young hammerheads as it was for 12 young sandbar sharks(沙堤鲨),which have normal-shaped heads. The two types of sharks proved equally adept at sensing the electric fields: each was able to detect the source from up to 30 centimetres away. That ruled out any improved sensitivity from the wider head. However, the hammerheads enjoy another more prosaic(平淡无奇的)advantage: their wider heads let them sweep more than twice as wide a swathe of the seafloor as they swim, which must boost their chance of encountering food. The researchers also found that hammerheads could turn more sharply when they detected the phantom prey. "They're a much more bendy shark , "says Kajlura, who is now at the University of California at Irvine. In part, that's because they have more slender bodies than the sandbar sharks. However, Kajiura has other unpublished data that suggests that the hammerheads' broad heads can act as fins to improve manoeuvrability(机动性). So far, the researchers have only experimented with young sharks, so adult hammerheads may gain some other advantage from their head shape.

单选题Sometimes it's just hard to choose. You're in a restaurant, and the waiter has his pen at the ready. As you hesitate, he gradually begins to take a close interest in the ceiling, his fingernails, then in your dining partner. Each dish on the menu becomes a blur as you roll your eyes up and down in a growing panic. Finally, you desperately opt for something that turns out to be what you hate. It seems that we need devices to protect us from our hopelessness at deciding between 57 barely differentiated varieties of stuff-be they TV channels, gourmet coffee, downloadable ring tones, or perhaps, ultimately even interchangeable lovers. This thought is opposed to our government's philosophy, which suggests that greater choice over railways, electricity suppliers and education will make us happy. In my experience, they do anything but. Perhaps the happiest people are those who do not have much choice and aren't confronted by the misery of endless choice. True, that misery may not be obvious to people who don't have a variety of luxuries. If you live in Madagascar, say, where average life expectancy is below 40 and they don't have digital TV or Starbucks, you might not be impressed by the anxiety and perpetual stress our decision - making paralysis causes. Choice wasn't supposed to make people miserable. It was supposed to be the hallmark of self-determination that we so cherish in capitalist western society. But it obviously isn't: ever more choice increases the feeling of missed opportunities, and this leads to self-blame when choices fail to meet expectations. What is to be done? A new book by an American social scientist, Barry Schwartz, called The Paradox of Choice, suggests that reducing choices can limit anxiety. Schwartz offers a self-help guide to good decision making that helps us to limit our choices to a manageable number, and ultimately derive greater satisfaction from the choices we make. This is a capitalist response to a capitalist problem. But once you realize that your Schwartzian filters are depriving you of something you might have found enjoyable, you will experience the same anxiety as before, worrying that you made the wrong decision in drawing up your choice-limiting filters. Arguably, we will always be doomed to buyers-remorse and the misery it entails. The problem of choice is perhaps more difficult than Schwartz allows.

单选题{{B}}Passage Five{{/B}} Federal Reserve System, central banking system of the United States, popularly called the Fed. A central bank serves as the banker to both the banking community and the government; it also issues the national currency, conducts monetary policy, and plays a major role in supervision and regulation of banks and bank holding companies. In the U.S. these functions are the responsibilities of key officials of the Federal Reserve System: the Board of Governors, located in Washington, D.C., and the top officers of the 12 district Federal Reserve banks, located throughout the nation. The Fed's actions, described below, generally have a significant effect on the U.S. interest rates and, subsequently, on stock, bond, and other financial markets. The Federal Reserve's basic powers are concentrated in the Board of Governors, which is paramount in all policy issues concerning bank regulation and supervision and in most aspects of monetary control. The board enunciates the Fed's policies on both monetary and banking matters. Because the board is not an operating agency, most of the day-to-day implementation of policies decisions is left to the district Federal Reserve banks, stock in which is owned by the commercial banks that are members of the Federal Reserve System. Ownership in this instance, however, does not imply control; the Board of Governors and the heads of the Reserve banks orient their policies to the public interest rather than to the benefit of the private banking system. The U.S. banking system's regulatory apparatus is complex; the authority of the Federal Reserve is shared in some instances for example, in mergers or the examination of banks with other federal agencies such as the Comptroller of the Currency and the Federal Deposit Insurance Cooperation (FDIC). In the critical area of regulating the nation's money supply in accordance with national economic goals, however, the Federal Reserve is independent within the government. Income and expenditures of the Federal Reserve banks and of the Board of Governors are not subject to the congressional appropriation process; the Federal Reserve is subject to the congressional appropriation process; the Federal Reserve is self-financing. Its income ($20.2 billion in 1992) comes mainly from Reserve bank holdings of income-earning securities, primarily those of the U.S. government. Outlays ($1.5 billion in 1992) are mostly for operational expenses in providing services to the government and for expenditures connected with regulation and monetary policy. In 1992 the Federal Reserve returned $16.8 billion in earnings to the U.S. Treasury.

单选题{{B}}Passage Five{{/B}} Most parents prize the diversity within their children's public schools. They know that learning to cooperate and excel in a diverse, real-world setting is a key to success in the 21st-century workplace and marketplace. But how "diverse" and "real-world" is a school that does not have any minority teachers? The bad news today is that some 40 percent of America's public schools have no teachers of color. The good news is that we have an opportunity to recruit and encourage more Americans of color to enter the teaching profession. And our success in doing so can have a powerfully positive impact on student achievement. Obviously, a teacher's effectiveness depends, first and foremost, on his or her skills and high expectations, not on the teacher's color. Yet we also know that children of color—40 percent of the student population and rising—benefit in important ways by having some teachers who look like them, who share similar cultural experiences, and who serve as role models demonstrating that education and achievement are things to be respected. Bear in mind that teachers do not teach only facts and "content". They also model appropriate behaviors and teach by personal example. And for many children, the teachers and other adults in their school are the most important authority figures outside of their home. So it is important to expose children to a diverse teaching staff—and to diverse role models—within each of our schools. Where we have an urban school with an all-minority staff or a suburban school with an all-white staff, we are giving students a stunted educational experience. Issues of diversity are especially relevant today, as public schools are redoubling their commitment to raising standards and closing achievement gaps. We need to seize every opportunity to boost the achievement of poor and minority students. I believe—and an impressive body of research confirms—that recruiting and retaining more minority teachers can be crucial to our success. NEA has made it a core strategic priority to increase the recruitment and retention of teachers of diverse backgrounds. Beyond NEA's own programs, we are joining with other organizations to create the National Collaborative on Diversity in the Teacher Workforce. But we can't do it alone. States and school districts need to develop programs to assist teacher's aides—large numbers of whom are minorities—to advance their education and become fully licensed teachers. Other programs can reach out to minorities still in school, offering encouragement and incentives to enter the teaching profession. At the same time, states must ensure that relevant tests do not bar promising minority candidates from entering the profession.
