单选题In recent years, railroads have been combining with each other, merging into super systems, causing heightened concerns about monopoly. As recently as 1995, the top four railroads accounted for under 70 per cent of the total ton-miles moved by rails. Next year, after a series of mergers is completed, just four rail roads will control well over 90 percent of all the freight moved by major rail carriers. Supporters of the new super systems argue that these mergers will allow for substantial cost reductions and better coordinated service. Any threat of monopoly, they argue, is removed by fierce competition from trucks. But many shippers complain that for heavy bulk commodities traveling long distances, such as coal, chemicals, and grain, trucking is too costly and the railroads therefore have them by the throat. The vast consolidation within the rail industry means that most shippers are served by only one rail company. Railroads typically charge such "captive" shippers 20 to 30 percent more than they do when another railroad is competing for the business. Shippers who feel they are being overcharged have the right to appeal to the federal government's Surface Transportation Board for rate relief, but the process is expensive, time consuming, and will work only in truly extreme cases. Railroads justify rate discrimination against captive shippers on the grounds that in the long nm it reduces everyone's cost. If railroads charged all customers the same average rate, they argue, shippers who have the option of switching to trucks or other forms of transportation would do so, leaving remaining customers to shoulder the cost of keeping up the line. It% theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. "Do we really want railroads to be the arbiters of who wins and who loses in the marketplace?" asks Mar- tin Bercovici, a Washington lawyer who frequently represents shipper. Many captive shippers also worry they will soon be his with a round of huge rate increases. The railroad industry as a whole, despite its brightening fortuning fortunes, still does not earn enough to cover the cost of the capital it must invest to keep up with its surging traffic. Yet railroads continue to borrow billions to ac- quire one another, with Wall Street cheering them on. Consider the $10. 2 billion bid by Norfolk Southern and CSX to acquire Conrail this year. Conrail's net railway operating income in 1996 was just $ 427 million, less than half of the carrying costs of the transaction. Who% going to pay for the rest of the bill? Many captive shippers fear that they will, as Norfolk Southern and CSX increase their grip on the market.

单选题The fear of Americanization of the planet is more ideological paranoia (多疑) than reality. There is no doubt that, with globalization, English has become the general language of our time, as was Latin in the Middle Ages. And it will continue its ascent, since it is an indispensable instrument for international transactions and communication. But does this mean that English necessarily develops at the expense of the other great languages? Absolutely not. In fact, the opposite is true. The vanishing of borders and an increasingly interdependent world have created incentives for new generations to learn and assimilate other cultures, not merely as a hobby, but also out of necessity, because the ability to speak several languages and navigate comfortably in different cultures has become crucial for professional success. Consider the case of Spanish. Half a century ago, Spanish speakers were an inward-looking community; we projected ourselves in only very limited ways beyond our traditional linguistic confines. Today, Spanish is dynamic and thriving, gaining beachheads or even vast landholdings on all five continents. That there are between 25 and 30 million Spanish speakers in the United States today explains why the two recent US presidential candidates—the Texas governor George W. Bush and the vice-president A1 Gore—campaigned not only in English, but also in Spanish. How many millions of young men and women around the globe have responded to the challenges of globalization by learning Japanese, German, Mandarin, Cantonese, Russian or French? Fortunately, this tendency will only increase in the coming years. That is why the best defence of our own cultures and languages is to promote them vigorously throughout this new world, not to persist in the naive pretense of vaccinating them against the menace of English. Those who propose such remedies speak much about culture, but they tend to be ignorant people who mask their true vocation: nationalism. And if there is anything at odds with the universalist propensities of culture, it is the exclusionary vision that nationalist perspectives try to impose on cultural life. The most admirable lesson that cultures teach us is that they need not be protected by bureaucrats or commissars, or confined behind iron bars, or isolated by customs services, in order to remain alive and exuberant; to the contrary, such efforts would only wither or even trivialile culture. Cultures must live freely, constantly jousting with different cultures. This renovates and renews them, allowing them to evolve and adapt to the continuous flow of life. In antiquity, Latin did not kill Greek; to the contrary, the artistic originality and intellectual depth of Hellenic culture permeated Roman civilization and, through it, the poems of Homer and the philosophies of Plato and Aristotle reached the entire world. Globalization will not make local cultures disappear; in a framework of worldwide openness, all that is valuable and worthy of survival in local cultures will find fertile ground in which to bloom.

单选题The Africans' interest is to guard preferential export rules enshrined in the temporary African Growth and Opportunity Act, passed by Congress in 2,000. Tariff-free exports of some 6,000 goods from Africa to the United States are boosting trade and investment in southern Africa. Lesotho's fast-growing textile industry depends almost entirely on Chinese investment in factories to make clothes for sale in the United States. The region also wants more access to America's markets for fruit, beef and other agricultural goods. American interest lies mainly in South Africa, by far the largest economy in the region. Services account for 60% of its GDP, and it increasingly dominates the rest of Africa in banking, information technology, telecom, retail' and other areas. Just as British banks, such as Barclays, have moved their African headquarters to South Africa over the past year, American investors see the country as a platform to the rest of the continent. Agreeing investment rules and resolving differences on intellectual property rights are the most urgent issues. American drug firms want to be part of the fast expansion in South Africa of production of anti-retroviral drugs, used against AIDS. By 2007 South Africa alone expects 1.2m patients to take the drugs daily. The country might be the world's biggest exporter of anti-AIDS drugs within a few years. Striking a bilateral deal now should make American investments easier. But Mr. Zoellick's greater concern is for multilateral trade talks that stalled in Cancun, Mexico, in September. Alec Erwin, his South African counterpart, helped to organize the G20 group of poor and middle-income countries that opposed joint American-EU proposals there; he is widely tipped to take over as head of the World Trade Organization late next year, and would be a useful ally. So Mr. Zoellick is trying to charm his African partner by agreeing to drop support for most of a group of issues (known as "Singapore" issues) that jammed up the talks at Cancun, and were opposed by poor countries; he says he also favors abolishing export subsidies in America--though only if Japan and the EU agree to do the same. That would please African exporters who say such subsidies destroy markets for their goods. Mr. Zoellick's efforts to make more friends may be paying off. Even though America has treated Africa very shabbily on trade in the past, Mr. Erwin hints it is easier doing business with America than with Europe or Japan. A small sign, but perhaps a telling one.

单选题It is a fair bet that more than half of the PCs bought this Christmas in America for less than $1 000 will have AMD rather than Intel inside. Not content with this seasonal miracle, Advanced Micro Devices is bidding to loosen Intel's grip on the more profitable high end of the market too. It could well succeed. For most of its existence, AMD has lived in the shadow of the deal that it did with Intel in 1982. To power its PCs, IBM had decided to buy Intel's new x-86 chips, but wanted a second supplier to keep Intel under control. Under the terms of the agreement, Intel got the contract, but had to share its intellectual property with the smaller AMD. Intel broke the arrangement, AMD started a lawsuit, and thus began nearly a decade of bitter legal battles between the two companies. The conflict misrepresented AMD's business, absorbed management energy and weakened investor confidence. By selling cheap Intel clones(克隆产品), AMD staggered (蹒跚，摇晃) on, sometimes quite successfully, especially if Intel was late to market with a new product. But despite the support of computer makers complaining under Intel's dominance, trying to get a lift on the back of an ill-tempered 8001b gorilla(大猩猩) was proving a risky form of existence. Eventually, under a settlement in 1995, AMD gave up any rights to Intel microcode. It was confident that its home-grown k5 would give Intel's Pentium a run for its money, while a new $1.8 billion plant in Texas would meet demand and match Intel's manufacturing skills. It did not. Design faults put the k5 more than two years behind the Pentium, and the Austin plant lay largely idle.

单选题Certainly, the most popular method of traveling used by Americans is the privately-owned automobile. The vast majority of Americans have a car, and many families have two.

单选题In bringing up children, every parent watches eagerly the child's acquisition (学会) 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 feelings of failure and states of worry 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 enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are sever over times of coming home at night or punctuality for meals. 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. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practise what they preach (说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.
