单选题What is the charm of necklaces? Why would anyone put something extra around her neck and then invest it with special significance? A necklace doesn"t afford warmth in cold weather, like a scarf, or protection in combat, like chain mail; it only decorates. We might say it borrows meaningfrom what it surrounds and sets off; the head with its supremely important material contents, and the face, that register of the soul. When photograph reduces the reality it represents, they mention not only the passage from three dimensions to two, but also the selection of a point du vue favors the top of the body rather than the bottom and the front rather than the back. The face is the jewel in the crown oi the body, and so we give it a setting. When people are intensely concerned with something that is obviously impractical, anthropologists take note, for lovely useless things often express archaic to exist in contemporary American houses already heated by gas and electricity, yet most people want one and it is still the focus of the living room. This desire testifies, I think, to the hundreds of thousands of years during which we Homo sapiens huddled around a cave fire. We watch ourselves, rather anxiously, vanish backward down those lone temporary corridors, as my daughter gazes at her infinitely multiplied small self in the mutually opposed mirrors of the beauty salon, and wonders, is it me? Our fireplaces and necklaces and tombstones say it is, they are. In American culture, an interest in necklaces seems to be rather gender specific. Many men to whom I mention the enterprise feign polite interest and then change the subject, though I know some who admire, construct, and wear necklaces, including the distinguished scientist and poet to whom this essay is dedicated. Most women, by contrast, become mildly or wildly enthusiastic. A doctor in Blois brought out her entire collection of costume jewelry for me, exhibited the most splendid pieces with an account of where and when they were purchased, and then explain them all with the help of a large glossy book on the history of costume jewelry , with dozens of pictures. A former student of mine who had moved to California mailed me six plastic boxes full of beads gleaned from a warehouse managed by an eccentric: friend who just their settings; a feature bead painted with a naked lady; crystal roundels of truly exceptional shine; and tiny silver hematite seed beads. Beads lend themselves to exchange, Beads travel. And clearly these two facts are related.

单选题{{B}}Part B{{/B}} The earth is witnessing an urban revolution, as people worldwide crowd into towns and cities. In 1800 only five per cent of the world's population were urban dwellers; now the proportion has risen to more than forty-five percent, and by the year 2010 more people will live in towns and cities than in the countryside. Humanity will, for the first time, have become a predominantly urban species. Though the world is getting more crowded by the day, absolute numbers of population are less important than where people concentrate and whether these areas can cope with them. Even densities, however, tell us nothing about the quality of the infrastructure—roads, housing and job creation, for example—or the availability of crucial services. The main question, then, is not how many people there are in a given area, but how well their needs can be met. Density figures have to be set beside measurements of wealth and employment, the quality of housing and the availability of education, medical care, clean water, sanitation and other vital services. The urban revolution is taking place mainly in the Third World, where it is hardest to accommodate. Between 1950 and 1985 the number of city dwellers grew more than twice as fast in the Third World as in industrialized countries. During this period, the urban population of the developed world increased from 477 million to 838 million, less than double; but it quadrupled in developing countries, from 286 million to 1.14 billion. Africa's urban population is racing along at five percent a year on average, doubling city numbers every fourteen years. By the turn of the century, three in every four Latin Americans will live in urban areas, as will two in every five Asians and one in every three Africans. Developing countries will have to increase their urban facilities by two thirds by then, if they are to maintain even their present inadequate levels of services and housing. In 1940 only one out of every hundred of the world's people lived in a really big city, one with a population of over a million. By 1980 this proportion had already risen to one in ten. Two of the world's biggest cities, Mexico and Sao Paulo, are already bursting at the seams—and their populations are doubling in less than twenty years. About a third of the people of the Third World's cities now live in desperately overcrowded slums and squatter settlements. Many are unemployed, uneducated, undernourished and chronically sick. Tens of millions of new people arrive every year, flocking in from the countryside in what is the greatest mass migration in history. Pushed out of the countryside by rural poverty and drawn to the cities in the hope of a better life, they find no houses waiting for them, no water supplies, no sewerage, no schools. They throw up makeshift hovels, built of whatever they can find. sticks, fronds, cardboard, tar-paper, straw, petrol tins and, if they are lucky, corrugated iron. They have to take the land none else wants; land that is too wet, too dry, too steep or too polluted for normal habitation. Yet all over the world the inhabitants of these apparently hopeless slums show extraordinary enterprise in improving their lives. While many settlements remain stuck in apathy, many others are gradually improved through the vigour and co-operation of their people, who turn flimsy shacks into solid buildings, build school, lay out streets and put in electricity and water supplies. Governments can help by giving the squatters the right to the land that they have usually occupied illegally, giving them the incentive to improve their homes and neighborhoods. The most important way to ameliorate the effects of the Third World's exploding cities, however, is to slow down the migration. This involves correcting the bias most governments show towards cities and towns and against the countryside. With few sources of hard currency, though, many governments in developing countries continue to concentrate their limited development efforts in cities and towns, rather than rural areas, where many of the most destitute live. As a result, food production falls as the countryside slides ever deeper into depression. Since the process of urbanization concentrates people, the demand for basic necessities, like food, energy, drinking water and shelter, is also increased, which can exact a heavy toll on the surrounding countryside. High-quality agricultural land is shrinking in many regions, taken out of production because of over-use and mismanagement. Creeping urbanization could aggravate this situation, further constricting economic development. The most effective way of tackling poverty, and of stemming urbanization, is to reverse national priorities in many countries, concentrating more resources in rural areas where most poor people still live. This would boost food production and help to build national economies more securely. Ultimately, though, the choice of priorities comes down to a question of power. The people of the countryside are powerless beside those of the towns; the destitute of the countryside may starve in their scattered millions, whereas the poor concentrated in urban slums pose a constant threat of disorder. In all but a few developing countries the bias towards the Cities will therefore continue, as will the migrations that are swelling their numbers beyond control.

单选题There are over 6,000 different computer and online games in the world now. A segment of them are considered to be both educational and harmlessly entertaining. One such game teaches geography, and another trains pilots. Others train the player in logical thinking and literate, which is more important in this technology-driven era. But the dark side of the computer games has become more and more obvious. "A segment of games features anti-social themes of violence, sex and crude language," says David Walsh, president of the National Institute on Media and Family. "Unfortunately. It"s a segment that seems particularly popular with kids aged from eight to fifteen." One study showed that almost 90 percent of the computer and online games young people preferred. Contained violence. The investigators said "There are not just games anymore. These are leaning machines. "We"re teaching kids in the most incredible manner what it"s like to pull the trigger. What they are not learning are the real-life consequences. They also said "The new and more sophisticated games are even worse, because they have better graphics and allow the player to participate in even more realistic violent acts." In the game Carmageddon, for example, the player will have driven over and killed up to 33,000 people by the time all levels are compelled. A description of the outcome of the game says: "Your victims not only squish under your tires and splatter blood on the windshield, they also get on their knees and beg for mercy, or commit suicide. If you like, you can also dismember them." Is all this simulated violence harmful? Approximately 3,000 different studies have been conducted on this subject. Many have suggested that there is a connection between violence in games and increased aggressiveness in the players. Some specialists downplay the influence of the games, saying that other factors must be taken into consideration, such as the possibility that kids who already have violent tendencies are choosing such games. But could it be that violent games still play a contributing role? It seems unrealistic to insist that people are not influenced by what they see. If that were true, why would the commercial world spend billions of dollars annually for television advertising?

单选题Trying to get Americans to eat a healthy diet is a frustrating business. Even the best-designed public-health campaigns cannot seem to compete with the tempting flavors of the snack-food and fast-food industries and their fat-and sugar-laden products. The results are apparent on a walk down any American street—more than 60% of Americans are overweight, and a full quarter of them are overweight to the point of obesity. Now, health advocates say, an ill-conceived redesign has taken one of the more successful public-health campaigns—the Food Guide Pyramid—and rendered it confusing to the point of uselessness. Some of these critics worry that America's Department of Agriculture caved in to pressure from parts of the food industry anxious to protect their products. The Food Guide Pyramid was a graphic which emphasizes that a healthy diet is built on a base of grains, vegetables and fruits, followed by ever-decreasing amounts of dairy products. meat, sweets and oils. The agriculture department launched the pyramid in 1992 to replace its previous program, which was centered on the idea of four basic food groups. The "Basic Four" campaign showed a plate divided into quarters, and seemed to imply that meat and dairy products should make up half of a healthy diet, with grains, fruits and vegetables making up the other half. It was replaced only over the strenuous objections of the meat and dairy industries. The old pyramid was undoubtedly imperfect. It failed to distinguish between a doughnut and a whole-grain roll, or a hamburger and a skinless chicken breast, and it did not make clear exactly how much of each foodstuff to eat. It did, however, manage to convey the basic idea of proper proportions in an easily understanable way. The new pyramid, called" My Pyramid", abandons the effort to provide this information. Instead, it has been simplified to a mere logo. The food groups are replaced with unlabelled, multi-colored vertical stripes which, in some versions, rise out of a cartoon jumble of foods that look like the aftermath of a riot at a grocery store. Anyone who wants to see how this translates into a healthy diet is invited to go to a website, put in their age, Sex and activity level, and get a Custom. designed pyramid, complete with healthy food choices and suggested portion sizes. This is fine for those who are motivated, but might prove too much effort for those who most need such information. Admittedly, the designers of the new pyramid had a tough job to do. They were supposed to condense the advice in the 84-page United States' Dietary Guidelines into a simple, meaningful graphic suitable for printing on the back of a cereal box. And they had to do this in the face of pressure from dozens of special interest groups—from the country's Potato, Board, which thought potatoes would look nice in the picture, to the Almond Board of California, which felt the same way about almonds. Even the National Watermelon Promotion Board and the California Avocado Commission were eager to sect heir products recognized. Nevertheless, many health advocates believe the new graphic is a missed opportunity. Although officials insist industry pressure had nothing to do with: the eventual design, some critics suspect that political influence was at work: On the other hand, it is not clear how much good even the best graphic could do. Surveys found that 80% of Americans recognized the old Food Guide Pyramid—a big success in the world of public, health campaigns. Yet only 16% followed its advice.

单选题At the present time, 98 percent of the world energy consumption comes from stored sources, such as fossil fuels or nuclear fuel. Only hydroelectric and wood energy represent completely renewable sources on ordinary time scales. Discovery of large additional fossil fuel reserves, solution of the nuclear safety and waste disposal problems, or the development of controlled thermonuclear fusion will provide only a short-term solution to the world's energy crisis. Within about 100 years, the thermal pollution resulting from our increased energy consumption will make solar energy a necessity at any cost. Man's energy consumption is currently about one part in ten thousand that of the energy we receive from the sun. However, it is growing at a 5 percent rate, of which about 2 percent represents a population growth and 3 percent a per capita energy increase. If this growth continues, within 100 years our energy consumption will be about 1 percent of the absorbed solar energy, enough to increase the average temperature of the earth by about one degree centigrade if stored energy continues to be our predominant source. This will be the point at which there will be significant effects in our climate, including the melting of the polar ice caps, a phenomenon which will raise the level of the oceans and flood parts of our major cities. There is positive feedback associated with this process, since the polar ice cap contributes to the partial reflectivity of the energy arriving from the sun: As the ice caps begin to melt, the reflectivity will decrease, thus heating the earth still further. It is often stated that the growth rate will decline or that energy conservation measures will preclude any long-range problem. Instead, this only postpones the problem by a few years. Conservation by a factor of two together with a maintenance of the 5 percent growth rate the problem by only 14 years. Reduction of the growth rate to 4 percent postpones the problem by only 25 years; in addition, the inequities in standards of living throughout the world will provide pressure toward an increase in growth rate, particularly if cheap energy is available. The problem of a changing climate will not be evident until perhaps ten years before it becomes critical due to the nature of an exponential growth rate together with the normal annual weather variations. This may be too short a period to circumvent the problem by converting to other energy sources, so advance planning is a necessity. The only practical means of avoiding the problem of thermal pollution appears to be the use of solar energy. (Schemes to "air-condition" the earth do not appear to be feasible before the twenty-second century. ) Using the solar energy before it is dissipated to heat does not increase the earth's energy balance. The cost of solar energy is extremely favorable now, particularly when compared to the cost of relocating many of our major cities.
