单选题Entrepreneurs are everybody's darlings these days. They may be small, but they are innovative. And innovation, we are assured, is the main engine of economic growth. For policymakers everywhere, the task is to get the little critters to nest and breed. Give them the conditions they like--plenty of venture capital, tax breaks and a risk-taking culture—and the sun will shine on all of us, just like in California. Along comes Amar Bhide to tell us most of this is plain wrong. Entrepreneurs, he asserts, are not risk-takers at all. Nor do most of them innovate, or depend on venture capital. His findings are striking enough. Start with his assertion that entrepreneurs are not innovators or risk-takers. The vast majority of new businesses, he points out, start small and stay that way. These are the hairdressing salons, corner shops and landscape gardeners. Those are mature, predictable industries. For just that reason, they are the least profitable. The success stories come in areas of high uncertainty, where markets are changing fast because of technology, regulation or fashion. A very large proportion, unsurprisingly, are in computing. But Mr. Bhide insists they are rarely innovative. The people who start high-growth businesses take a humdrum idea, usually from someone else, then change it constantly to fit the market. The starting point is much less important than what happens next. Nor are they risk-takers. These are typically young people, with no money, expertise or status. They have nothing to lose. Risk arrives later on, when they have made their pile and must decide whether to invest in long-term growth or sell out. This is one reason why so few promising start-ups become a Dell or Microsoft. Taking planned, calculated risks is the job of big, established companies, Mr. Bhide argues. True entrepreneurs rarely have the temperament for it. What they have, instead, is a high tolerance for ambiguity--defined as knowledge that you know you do not have. Few of Mr. Bhide's interviewees began with any kind of business plan. That would have been a waste of time: the future was simply too uncertain. Therein lay their opportunity. Big companies may be happy with risk, but they cannot stand ambiguity. They can invest billions in a chip plant or oil field, but only when they know the odds. When the odds are unknown, entrepreneurs have the game to themselves.

单选题Where one stage of child development has been left out, or not sufficiently experienced, the child may have to go back and capture the experience of it. A good home makes this possible, for example, by providing the opportunity for the child to play with a clockwork car or toy railway train up to any age if he still needs to do so. This principle, in fact, underlies all psychological treatment of children in difficulties with their development, and is the basis of work in child clinics. The beginnings of discipline are in the nursery. Even the youngest baby is taught by gradual stages to wait for food, to sleep and wake at regular intervals and so on. If the child feels the world around him is a warm and friendly one, he slowly accepts its rhythm and accustoms himself to conforming to its demands. Learning to wait for things, particularly for food, is a very important element in upbringing, and is achieved successfully only if too great demands are not made before the child can understand them. Every parent watches eagerly the child's acquisition of each new skill—the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feeling of failure and states of anxiety in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural zest for life and his desire to find out new things for himself. Learning together is a fruitful source of relationship between children and parents. By playing together, parents learn more about their children and children learn more from their parents. Toys and games which both parents and children can share are an important means of achieving this cooperation. Building-block toys, jigsaw puzzles and crossword are good examples. Parents vary greatly in their degree of strictness or indulgence towards their children. Some may be especially strict in money matters; others are severe over times of coming home at night, punctuality for meals or personal cleanliness. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness and well-being.

单选题Visiting a National Park can be relaxing, inspiring, but it can also be disturbing. As you drive into Rocky Mountain National Park, you will see starving elk, damaged mead ows and dying forests. Our parks are growing old because we have mistakenly protected them from natural processes, such as fire, predation, and insects. We believed that we were saving these remnants of wild America, but actually we have "protected" them to death. If we want to save our National Parks, the National Park Service must change its management priorities to prevent over population of animals and to restore natural process in the forest in order to prevent their stagnation and "death" by old age. We must act soon: our parks are dying of old age because we have altered the forces in nature that keep them young and strong. By tracing the history of our National Parks, we can understand the problem and see why we need active management. In the early part of the 20th century, settlers exploited wildlife heavily, resulting in neat-extinction of many species. Therefore, several National Parks were established by Congress primarily to save endangered animals. However, stricter wildlife protection laws and improved wildlife management techniques resulted in greater populations of animals overcrowding in areas of high concentration, such as the Yellowstone elk herds. Complicating the problem, the National Park Service in the early part of the 20th century adopted a policy of aggressive predator elimination, thus reducing natural wildlife population control. Subsequently, elk and deer populations exploded in many National Parks, resulting in severe damage to native vegetation. Vigorous forest fire and insect suppression in the National Parks throughout the 20th century further altered the natural environment by allowing forests to over-mature, without natural thinning processes. Park managers thought that they were protecting the land, but actually they were removing important controls from the forest ecosystems. Clearly, we must act immediately if we want to pass down to our children and grandchildren the green legacy of our National Parks; we must step in and restore the natural processes which we have altered through our well-intentioned, but misguided, policies in the past.

单选题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.
