单选题 Governments that want their people to prosper in the burgeoning world economy should guarantee two basic rights: the right to private property and the right to enforceable contracts, says Mancur Olson in his book Power and Prosperity. Olson was an economics professor at the University of Maryland until his death in 1998. Some have argued that such rights are merely luxuries that wealthy societies bestow, but Olson turns that argument around and asserts that such rights are essential to creating wealth. "In comes are low in most of the countries of the world, in short, because the people in those countries do not have secure in dividual rights," he says. Certain simple economic activities, such as food gathering and making handicrafts, rely mostly on individual labor; property is not necessary. But more advanced activities, such as the mass production of goods, require machines and factories and offices. This production is often called capital-intensive, but it is really property-intensive, Olson observes. "No one would normally engage in capital-intensive production if he or she did not have rights that kept the valuable capital from being taken by bandits, whether roving or stationary," he argues. "There is no private property without government—individuals may have possessions, the way a dog possesses a bone, but there is private property only if the society protects and defends a private right to that possession against other private parties and against the government as well." Would-be entrepreneurs, no matter how small, also need a government and court system that will make sure people honor their contracts. In fact, the banking systems relied on by developed nations are based on just such an enforceable contract system. "We would not deposit our money in banks...if we could not rely on the bank having to honor its contract with us, and the bank would not be able to make the profits it needs to stay in business if it could not enforce its loan contracts with borrowers," Olson writes. Other economists have argued that the poor economies of Third World and communist countries are the result of governments setting both prices and the quantities of goods produced rather than letting a free market determine them. Olson agrees there is some merit to this point of view, but he argues that government intervention is not enough to explain the poverty of these countries. Rather, the real problem is lack of individual rights that give people incentive to generate wealth. "If a society has clear and secure individual rights, there are strong incentives (刺激，动力) to produce, invest, and engage in mutually advantageous trade, and therefore at least some economic advance," Olson concludes.

单选题Awarded the Nobel Prize for physics in 1918, German physicist Max Planck is best remembered as the originator of the quantum theory. His work helped usher in a new era in theoretical physics and revolutionized the scientific community's understanding of atomic and subatomic processes. Planck introduced an idea that led to the quantum theory, which became the foundation of 20th century physics. In December 1900, Planck worked out an eqation that described the distribution of radiation accurately over the range of low to high frequencies. He had developed a theory which depended on a model of matter that seemed very strange at the time. The model required the emission of eletromagnetic radiation in small chunks or particles. These particles were later called quantums. The energy associated with each quantum is measured by multiplying the frequency of the radiation,v, by a universal constant, h. Thus, energy, or E, equals hv. The constant, h, is known as Planck's constant. It is now recognized as one of the fundamental constants of the world. Planck announced his findings in 1900, but it was years before the full consequences of his revolutionary quantum theory were recognized. Throughout his life, Planck made significant contributions to optics, thermodynamics and statistical mechanics, physical chemistry, and other fields. In 1930 he was elected president of the Kaiser Wilhelm Society, which was renamed the Max Planck Society after World War Ⅱ. Though deeply opposed to the facist regime of Adolf Hitler, Planck remained in Germany throughout the war. He died in Gottingen on October 4,1947.

单选题Exceptional children are different in some significant way from others of the same age. For these children to develop to their full adult potential, their education must be adapted to those differences. Although we focus on the needs of exceptional children, we find ourselves describing their environment as well. While the leading actor on the stage captures our attention, we are aware of the importance of the supporting players and the scenery of the play itself. Both the family and the society in which exceptional children live are often the key to their growth and development. And it is in the public schools that we find the full expression of society's understanding — the knowledge, hopes, and fears that are passed on to the next generation. Education in any society is a mirror of that society. In that mirror we can see the strengths, the weaknesses, the hopes, the prejudices, and the central values of the culture itself. The great interest in exceptional children shown in public education over the past three decades indicates the strong feeling in our society that all citizens, whatever their special conditions, deserve the opportunity to fully develop their capabilities. "All men are created equal. " We've heard it many times, but it still has important meaning for education in a democratic society. Although the phrase was used by this country's founders to denote equality before the law, it has also been interpreted to mean equality of opportunity. That concept implies educational opportunity for all children — the right of each child to receive help in learning to the limits of his or her capacity, whether that capacity be small or great. Recent court decisions have confirmed the right of all children — disabled or not — to an appropriate education, and have ordered that public schools take the necessary steps to provide that education. In response, schools are modifying their programs, adapting instruction to children who are exceptional, to those who cannot profit substantially from regular programs.

单选题Since its foundation in 1945, the United Nations has written into its major covenants the need to establish minimum ages for marriage, but the custom of marriage is a highly sensitive cultural issue, mainly because it is so unpleasantly involved with women's rights and societal traditions and practices, and rules on marriage vary widely between countries.

单选题The newspaper report ______ with the account of the accident on the radio.

单选题It is not often realized that women held a high place in southern European societies in the 10th and 11th centuries. As a wife, the woman was protected by the setting up of a dowry or decimum. Admittedly, the purpose of this was to protect her against the risk of desertion, but in reality its function in the social and family life of the time was much more important. The decimum was the wife's right to receive a tenth of all her husband's property. The wife had the right to withhold consent, in all transactions the husband would make. And more than just a right: the documents show that she enjoyed a real power of decision, equal to that of her husband, in no case do the documents indicate any degree of difference in the legal status of husband and wife. The wife shared in the management of her husband's personal property, but the opposite was not always true. Women seemed perfectly prepared to defend their own inheritance against husbands who tried to exceed their rights, and on occasion they showed a fine fighting spirit. A case in point is that of Maria Vivas, a Catalanwoman of Barcelona. Having agreed with her husband Miro to sell a field she had inherited, for the needs of the household, she insisted on compensation. None being offered, she succeeded in dragging her husband to the scribe to have a contract duly drawn up assigning her a piece of land from Miro's personal inheritance. The unfortunate husband was obliged to agree, as the contract says, "for the sake of peace". Either through the dowry or through being hot-tempered, the Catalan wife knew how to win herself, within the context of the family, a powerful economic position.
