单选题{{B}}Text 4{{/B}} The U.S. Supreme Court's decision Monday to let stand a ruling in an online defamation case will make it more difficult to determine correct legal jurisdictions in other Internet eases, legal experts said. By opting not to take the case, the high court effectively endorsed a lower court's decision that a Colorado company that posts ratings of health plans on the Internet could be sued for defamation in a Washington court. The lower court ruling is one of several that makes it easier for plaintiffs to sue Web site operators in their own jurisdictions, rather than where the operators maintain a physical presence. The case involved a defamation suit filed by Chehalis, Wash.-based Northwest Healthcare Alliance against Lakewood, Colo. -based Healthgrades.com. The Alliance sued in Washington federal court after Healthgrades. com posted a negative ranking of Northwest Healthcare's home health services on the Internet. Healthgrades. com argued that it should not be subject to the jurisdiction of a court in Washington because its publishing operation is in Colorado. Observers said the fact that the Supreme Court opted not to hear the case only clouds the legal situation for Web site operators. Geoff Stewart, a partner at Jones Day in Washington, D. C. , said that the Supreme Court eventually must act on the issue, as Internet sites that rate everything from automobile dealerships to credit offers could scale back their offerings to avoid lawsuits originating numerous jurisdictions. Online publishers also might have to worry about being dragged into lawsuits in foreign courts, said Dow Lohnes ＆ Albertson attorney Jon Hart, who has represented the Online News Association. "The much more difficult problems for U. S. media companies arise when claims are brought in foreign countries over content published in the United States," Hart said. Hart cited a recent case in which an Australian court ruled that Dow Jones must appear in a Victoria, Australia court to defend its publication of an article on the U. S. -based Watt Street Journal Web site. According to Hart, the potential chilling effect of those sorts of jurisdictional decisions is substantial. "I have not yet seen publishers holding back on what they otherwise publish because they're afraid they're going to get sued in another country, but that doesn't mean it Won't happen if we see a rash of U. S. {{U}}libel{{/U}} cases against U. S. media companies being brought in foreign countries," he said. Until the high court decides to weigh in directly on this issue, Web site operators that offer information and services to users located outside of their home states must deal with a thorny legal landscape, said John Morgan, a partner at Perkins Coie LLP and an expert in Internet law.

单选题{{B}}Text 3{{/B}} A patent is an exclusive right given to an inventor for his or her invention. In other words, a patent is a monopoly right given to the inventor for the invention. A patent confers on the inventor the right to price and to sell the invention in any way he or she desires, in the United States, patents are granted by the Patent Office for 17 years. Although economists generally condemn monopoly as a form of market organization since monopoly imposes costs on the economy, patents present a more subtle case for monopoly theory. Specifically, can patent monopolies be justified? In general, economists complain about the costs of monopoly because they believe that the same industry could be organized competitively. A patent monopoly grant for 17 years presents a different problem. That is, the purpose of the patent system is to encourage invention. The issue is not monopoly versus competition but, more fundamentally, invention versus no invention. Is the world better off with the invention, even though it is monopolized for 17 years? In other words, what are the costs and benefits of a patent? Consider the simple case of a new consumer product with a positive demand, such as a camera utilizing a new exposure process. The costs of the patent monopoly are simply the deadweight costs of monopoly measured by the lost consumers' surplus from the 17-year patent monopoly. This cost must be assessed carefully in the context of an invention, however. What are the benefits of the patent system? First, there is the increase in consumer well-being brought about immediately by a desirable invention. In 17 years, the patent monopoly ends, and a second source of benefits arises: The price of cameras will fall to a competitive level, and consumers will reap the benefits of the camera at a lower price. In sum, theory of monopoly helps us to assess the costs and benefits of the patent. One can quibble about patent monopolies, arguing, for example, that they are granted for too long a time. In the end, the patent system creates goods and services and technologies that did not previously exist. In this respect it is a valuable System for the economy. The patent system also underscores the importance of property rights to ideas as a source of economic growth and progress.

单选题In most people's mind, growth is associated with prosperity. We judge how well the economy is doing by the size of the Gross National Product (GNP), a measure, supposedly, of growth. Equally axiomatic, however, is the notion that increased pressure on declining natural resources must inevitably lead to a decline in prosperity, especially when accompanied by a growth in population. So, which is correct? What growth advocates mean, primarily, when they say growth is necessary for prosperity is that growth is necessary for the smooth functioning of the economic system. In one field the argument in favor of growth is particularly compelling and that is with regard to the Third World. To argue against growth in light of Third World poverty and degradation seems unsympathetic. But is it? Could it be that growth, especially the growth of the wealthier countries, has contributed to the impoverishment, not the advancement, of Third World countries? If not, how do we account for the desperate straits these countries find themselves in today after a century of dedication to growth? To see how this might be the case we must look at the impact of growth on Third World countries—the reality, not the abstract stages-of-economic-growth theory advocated through rose colored glasses by academicians of the developed world. What good is growth to the people of the Third World if it means the conversion of peasant farms into mechanized agri-businesses producing commodities not for local consumption but for export, if it means the stripping of their land of its mineral and other natural treasures to the benefit of foreign investors and a handful of their local collaborators, if it means the assumption of a crushing foreign indebtedness? Admittedly, this is an oversimplification. But the point, I believe, remains valid: that growth in underdeveloped countries cannot simply be judged in the abstract; it must be judged based on the true nature of growth in these societies, on who benefits and who is harmed, on where growth is leading these people and where it has left them. When considered in this way, it just might be that in the present context growth is more detrimental to the well-being of the wretched of the earth than beneficial. So, do we need growth for prosperity? Only the adoption of zero growth can provide the answer. But that is a test not easily undertaken. Modem economies are incredibly complex phenomena, a tribute to man's ability to organize and a challenge to his ability to understand. Anything that affects their functioning, such as a policy of zero growth, should not be proposed without a wary carefulness and self-doubting humility. But if the prospect of leaping into the economic unknown is fear-inspiring, equally so is the prospect of letting that fear prevent us from acting when the failure to act could mean untold misery for future generations and perhaps environmental disaster which threaten our very existence.

单选题{{B}}Text 3{{/B}} For me, scientific knowledge is divided into mathematical sciences, natural sciences or sciences dealing with the natural world (physical and biological sciences), and sciences dealing with mankind (psychology, sociology, all the sciences of cultural achievements. every kind of historical knowledge). Apart from these sciences is philosophy, about which we will talk later. In the first place, all this is pure or theoretical knowledge, sought only for the purpose of understanding, in order to fulfill the need to understand that is intrinsic and con-substantial to man. What distinguishes man from animals is that he knows and needs to know. If man did not know that the world existed, and that the world was of a certain kind, that he was in the world and that he himself was of a certain kind, he wouldn't be man. The technical aspects or applications of knowledge are equally necessary for man and are of the greatest importance, because they also contribute to defining him as man and permit him to pursue a life increasingly more truly human. But even while enjoying the results of technical progress, man must defend the primacy and autonomy of pure knowledge. Knowledge sought directly for its practical applications will have immediate and foreseeable success, but not the kind of important result whose revolutionary scope is for the most part unforeseen, except by the imagination of the Utopians. Let me recall a well-known example. If the Greek mathematicians had not applied themselves to the investigation of conic section zealously and without the least suspicion that it might someday be useful, it would not have been possible centuries later to navigate far from shore. The first men to study the nature of electricity could not imagine that their experiments, carried on because of mere intellectual curiosity, would eventually lead to modern electrical technology, without which we can scarcely conceive of contemporary life. Pure knowledge is valuable for its own sake, because the human spirit cannot resign itself to ignorance. Butt in addition, it is the foundation for practical results that would not have been reached if this knowledge had not been sought disinterestedly. {{B}}Notes:{{/B}} intrinsic 固有的。con-substantial 同体的。autonomy 自主性。zealously and without the least suspicion热情地并丝毫也没有想到。for the most part 大部分，主要地。Utopian乌托邦，理想主义。disinterestedly 不偏不倚地。resign oneself to 听任，顺从。

单选题It was a ruling that had consumers seething with anger and many a free trader crying foul. On November 20th the European Court of Justice decided that Tesco, a British supermarket chain, should not be allowed to import jeans made by America's Levi Strauss from outside the European Union and sell them at cut-rate prices without getting permission first from the jeans maker. Ironically, the ruling is based on an EU trademark directive that was designed to protect local, not American, manufacturers from price dumping. The idea is that any brand-owning firm should be allowed to position its goods and segment its markets as it sees fit: Levi's jeans, just like Gucci handbags, must be allowed to be expensive. Levi Strauss persuaded the court that, by selling its jeans cheaply alongside soap powder and bananas, Tesco was destroying the image and so the value of its brands—which could only lead to less innovation and, in the long run, would reduce consumer choice. Consumer groups and Tesco say that Levi's case is specious. The supermarket argues that it was just arbitraging the price differential between Levi's jeans sold in America and Europe—a service performed a million times a day in financial markets, and one that has led to real benefits for consumers. Tesco has been selling some 15,000 pairs of Levi's jeans a week, for about half the price they command in specialist stores approved by Levi Strauss. Christine Cross, Tesco's head of global non-food sourcing, says the ruling risks "creating a Fortress Europe with a vengeance". The debate will rage on, and has implications well beyond casual clothes (Levi Strauss was joined in its lawsuit by Zino Davidoff, a perfume maker). The question at its heart is not whether brands need to control how they are sold to protect their image, but whether it is the job of the courts to help them do this. Gucci, an Italian clothes label whose image was being destroyed by loose licensing and over-exposure in discount stores, saved itself not by resorting to the courts but by ending contracts with third-party suppliers, controlling its distribution better and opening its own stores. It is now hard to find cut-price Gucci anywhere. Brand experts argue that Levi Strauss, which has been losing market share to hipper rivals such as Diesel, is no longer strong enough to command premium prices. Left to market forces, so-so brands such as Levi's might well fade away and be replaced by fresher labels. With the courts protecting its prices, Levi Strauss may hang on for longer. But no court can help to make it a great brand again.
