单选题 Ocean water plays an indispensable role in supporting life. The great ocean basins hold about 300 million cubic miles of water. From this vast amount; about 80,000 cubic miles of water are sucking into the atmosphere each year by evaporation and returned by precipitation and drainage to the ocean. More than 24,000 cubic miles of rain descend annually upon the continents. This vast amount is required to replenish the lakes and streams, springs and water tables on which all flora and fauna are dependent. Thus, the hydrosphere permits organism existence. The hydrosphere has strange characteristics because water has properties unlike those of any other liquid. One anomaly is that water upon freezing expands by about 9 percent, whereas most liquids contract on cooling. For this reason, ice floats on water bodies instead of sinking to the bottom. If the ice sank, the hydrosphere would soon be frozen solidly, except for a thin layer of surface melt water during the summer season. Thus, all aquatic life would be destroyed and the interchange of warm and cold currents, which moderates climate, would be notably absent. Another outstanding characteristic of water is that it has a heat capacity which is the highest of all liquids and solids except ammonia. This characteristic enables the oceans to absorb ard store vast quantities of heat, thereby often preventing climatic extremes. In addition, water dissolves more substances than any other liquid. It is this characteristic which helps make oceans a great storehouse for minerals which have been washed down from the continents. In several areas of the world these minerals are being commercially exploited. Solar evaporation of salt is widely practiced, potash is extracted from the Dead Sea, and Magnesium is produced from seawater along the American Gulf Coast.

单选题It happened in the late fall of 1939 when, after a Nazi submarine had penetrated the British sea defense around the Firth of Forth and damaged a British cruiser, Reston and a colleague contrived to get the news past British censorship. They cabled a series of seemingly harmless sentences to The Times's editors in New York, having first sent a message instructing the editors to regard only the last word of each sentence. Thus they were able to convey enough words to spell out the story. The fact that the news of the submarine attack was printed in New York before it had appeared in the British press sparked a big controversy that led to an investigation by Scotland Yard and British Military Intelligence. But it took the investigators eight weeks to decipher The Times's reporters' code, an embarrassingly slow bit of detective work, and when it was finally solved the incident had given the story very prominent play, later expressed dismay that the reporters had risked so much for so little. And the incident left Reston deeply distressed. It was so out of character for him to have. become involved in such a thing. The tactics were questionable and, though the United States was not yet in the war, Britain was already established as America's close ally and breaking British censorship seemed both an irresponsible and unpatriotic thing to do.

单选题{{B}}Passage 3{{/B}} Despite Denmark's manifest virtues, Danes never talk about how proud they are to be Danes. This would sound weird in Danish. When Danes talk to foreigners about Denmark, they always begin by commenting on its tininess, its unimportance, the difficulty of its language, the general small-mindedness and self=indulgence of their countrymen and the high taxes. No Dane would look you in the eye and say, "Denmark is a great country. " You're supposed to figure this out for yourself. It is the land of the silk safety net, where almost half the national budget goes toward smoothing out life's inequalities, and there is plenty of money for schools, day care, retraining programs, job seminars—Danes love seminars: Three days at a study center hearing about waste management is almost as good as a ski trip. It is a culture bombarded by English, in advertising, pop music, the Internet, and despite all the English that Danish absorbs—there is no Danish Academy to defend against it—old dialects persist in Jutland that can barely be understood by Copenhageners. It is the land where, as the saying goes, "Few have too much and fewer have too little," and a foreigner is struck by the sweet egalitarianism that prevails, where the lowliest clerk gives you a level gaze, where Sir and Madame have disappeared from common usage, even Mr. and Mrs. It's a nation of recyclers—about 55% of Danish garbage gets made into something new—and no nuclear power plants. It's a nation of tireless planners. Trains run on time. Things operate well in general. Such a nation of overachievers—a brochure from the Ministry of Business and Industry says, "Denmark is one of the world's cleanest and most organized countries, with virtually no pollution, crime, or poverty. Denmark is the most corruption-free society in the Northern hemisphere. " So, of course, one's heart lifts at any sighting of Danish sleazy: skinhead graffiti on buildings ("Foreigners Out of Denmark!"), broken beer bottles in the gutters, drunken teenagers slumped in the park. Nonetheless, it is an orderly land. You drive through a Danish town, it comes to an end at a stone wall, and on the other side is a field of barley, a nice clean line: town here, country there. It is not a nation of jaywalkers. People stand on the curb and wait for the red light to change, even if it's 2 a. m. and there's not a car in sight. However, Danes don't think of themselves as a waiting-at-2-a, m.-for-the-green-light people—that's how they see Swedes and Germans. Danes see themselves as jazzy people, improvisers, more free spirited than Swedes, but the truth is (though one should not say it) that Danes are very much like Germans and Swedes. Orderliness is a main selling point. Denmark has few natural resources, limited manufacturing capability; its future in Europe will be as a broker, banker, and distributor of goods. You send your goods by container ship to Copenhagen, and these bright, young, English-speaking, utterly honest, highly disciplined people will get your goods around to Scandinavia, the Baltic States, and Russia. Airports, seaports, highways, and rail lines are ultramodern and well-maintained. The orderliness of the society doesn't mean that Danish lives are less messy or lonely than yours or mine, and no Dane would tell you so. You can hear plenty about bitter family feuds and the sorrows of alcoholism and about perfectly sensible people who went off one day and killed themselves. An orderly society cannot exempt its members from the hazards of life. But there is a sense of entitlement and security that Danes grow up with. Certain things are yours by virtue of citizenship, and you shouldn't feel bad for taking what you're entitled to, you're as good as anyone else. The rules of the welfare System are clear to everyone, the benefits you get if you lose your job, the steps you take to get a new one; and the orderliness of the system makes it possible for the country to weather high unemployment and social unrest without a sense of crisis.

单选题Passage 2 Throughout the nineteenth century and into the twentieth, citizens of the United States maintained a bias against big cities. Most lived on farms and in small towns and believed cities to be centers of corruption, crime, poverty, and moral degradation. Their distrust was caused, in part, by a national ideology that proclaimed farming the greatest occupation and rural living superior to urban living. This attitude prevailed even as the number of urban dwellers increased and cities became an essential feature of the national landscape. Gradually, economic reality overcame ideology. Thousands abandoned the precarious life on the farm for more secure and better paying jobs in the city. But when these people migrated from the countryside, they carried their fears and suspicions with them. These new urbanites, already convinced that cities were overwhelmed with great problems, eagerly embraced the progressive reforms that promised to bring order out of the chaos of the city. One of many reforms came in the area of public utilities. Water and sewerage system were usually operated by municipal governments, but the gas and electric networks were privately owned. Reformers feared that the privately owned utility companies would change exorbitant rates for these essential services and deliver them only to people who could afford them. Some city and state governments responded by regulating the utility companies, but a number of cities began to supply these services themselves. Proponents of these reforms argued that public ownership and regulation would insure widespread access to these utilities and guarantee a fair price. While some reforms focused on government and public behavior, others looked at the cities as a whole. Civic leaders, convinced that physical environment influenced human behavior, argued that cities should develop master plans to guide their future growth and development. City planning was nothing new, but the rapid industrialization and urban growth of the late nineteenth century took place without any consideration for order. Urban renewal in the twentieth century followed several courses. Some cities introduced plans to completely rebuild the city core. Most other cities contented themselves with zoning plans for regulating future growth. Certain parts of town were restricted to residential use, while others were set aside for industrial or commercial development.
