单选题One November evening in 1989 I was loafing in my room at university when a friend began thumping on the door. "What is it?" I shouted irritably. "The Berlin Wall just fell," he shouted back For months afterwards I walked around in a daze of wonder, as crowds ransacked secret-police headquarters and Nelson Mandela walked out of jail. Two lines from Wordsworth about the French Revolution, which I"d read in some article about the1989 revolutions, kept going through my mind: Bliss was it in that dawn to be alive, But to be young was very heaven! It was the most optimistic political moment I"ve lived through, my generation"s version of 1945 or 1968. 6 . Now we"re at the peak of political pessimism. The political year is opening with almost nobody on either right or left expecting anything good. The great questions seem to be: how will an intervention in Syria go wrong? And will the US House of Representatives vote to repeal "Obamacare" for the 41st time? 7 The utopian urge persists; it has just migrated from politics to technology. Instead of developing a political policy to solve a problem, people now develop an app. In politics, you can hardly count all the lights that have failed since the invasion of Iraq a decade ago. Faith in unregulated capitalism died with Lehman Brothers. Then Barack Obama, the Occupy movements and the Tea Party all rapidly disappointed their followers. In 2009 in Copenhagen, it became clear the world wouldn"t agree to combat climate change. Now the Arab spring is eating its own children, the Russian demonstrators have gone home, and hardly anyone believes in the European project any more. 8 , even before its intellectual underpinning was revealed as an academic paper whose authors had accidentally left important bits of data off their spreadsheet. The western liberating impulse-previously directed at Iraq, Iran and Cuba-has died too. Myanmar finally opened up, and ethnic conflict promptly began. Even people who believed in al-Qaeda are now presumably disillusioned. It"s hard to find a self-proclaimed political messiah anywhere: Hugo Chavez is dead, and Fidel Castro himself says Cuba"s revolution has failed. Politicians have been reduced to celebrities who can gain our attention only with Anthony Weineresque private antics. 9 Meanwhile a rash of TV series like House of Cards, Veep and The Thick of It portray politics as a greedy, narcissistic pursuit. No wonder political parties are shedding members at record speed. The last emotion that still animates tots of western voters is rage at immigrants-an archetypal expression of pessimism. Andrew Adonis, leading thinker of the UK"s Labour party, says : "We"re in one of those periods like the 1970s where politicians manifestly don"t have the answers. " But meanwhile a group of people has stood up who do claim to have answers: technologists. In 2007, just as western economies began to crumble, Apple launched the iPhone. 10 The latter took time to decide how to use their new might. Nicole Boyer, director of the Adaptive Edge consultancy in San Francisco, explains: "Tech was late to the game for social problems. It took a generation of tech entrepreneurs to make money and then say, "OK, what are we going to do?" Now they are busy remaking the world: Google"s Erie Schmidt negotiates with North Korea, Jeff Bezos tries to save newspapers, Mark Zuckerberg plots to get the world"s poor online and Bill Gates fights infectious disease. "They have something of the white knight about them," muses Adonis. "There is a profound tech-optimism." In this budding tech-utopia, government scarcely features. Great technological achievements of the past—the atomic bomb, the moon landing and even the internet—began within the US government. Today, whether people like government or loathe it, they mostly ignore it. A. Austerity became the latest light to fail B. Since then, credibility has kept leaching from politicians to techies C. Strangely, it actually turned out pretty well D. But hope springs eternal E. Mandela on his deathbed still towers over today"s lot

单选题[1] To say that the city is a central problem of American life is simply to know that increasingly the cities are American life; just as urban living is becoming the condition of man across the world. Everywhere men and women crowd into cities in search of employment, a decent living, the company of their fellows, and the excitement and stimulation of urban life. [2] Within a very few years, 80 percent of all Americans will live in cities — the great majority of them in concentrations like those which stretch from Boston to Washington, and outward from Chicago and Los Angeles and San Francisco and St. Louis. The cities are the nerve system of economic life for the entire Nation, and for much of the world. [3] And each of our cities is now the seat of nearly all the problems of American life: poverty and race hatred, stunted education and saddened lives, and the other ills of the new urban Nation — congestion and filth, danger and purposelessness — which afflict all but the very rich and the very lucky. [4] ...The city is not just housing and stores. It is not just education and employment, parks and theaters, banks and shops. It is a place where men should be able to live in dignity and security and harmony, where the great achievements of modern civilization and the ageless pleasures afforded by natural beauty should be available to all. If this is what we want — and this is what we must want if men are to be free for that "pursuit of happiness" which was the earliest promise of the American Nation — we will need more than poverty programs, housing programs, and employment programs, although we will need all of these. We will need an outpouring of imagination, ingenuity, discipline, and hard work unmatched since the first adventurers set out to conquer the wilderness. For the problem is the largest we have ever known. And we confront an urban wilderness more formidable and resistant and in some ways more frightening than the wilderness faced by the pilgrims or the pioneers. [5] One great problem is sheer growth — growth which crowds people into slums, thrusts suburbs out over the countryside, burdens to the breaking point all our old ways of thought and action — our systems of transport and water supply and education, and our means of raising money to finance these vital services. [6] A second is destruction of the physical environment, stripping people of contact with sun and fresh air, clean rivers, grass and trees — condemning them to a life among stone and concrete, neon lights and an endless flow of automobiles. This happens not only in the central city, but in the very suburbs where people once fled to find nature. "There is no police so effective," said Emerson, "as a good hill and a wide pasture... where the boys...can dispose of their superfluous strength and spirits." We cannot restore the pastures, but we must provide a chance to enjoy nature, a chance for recreation, for pleasure and for some restoration of that essential dimension of human existence which flows only from man's contact with the natural world around him. [7] A third is the increasing difficulty of transportation — adding concealed, unpaid hours to the workweek, removing men from the social and cultural amenities that are the heart of the city; sending destructive swarms of automobiles across the city, leaving behind them a band of concrete and a poisoned atmosphere. And sometimes — as in Watts — our surrender to the automobile has so crippled public transport that thousands literally cannot afford to go to work elsewhere in the city. [8] A fourth destructive force is the concentrated poverty and racial tension of the urban ghetto — a problem so vast that the barest recital of its symptoms is profoundly shocking: Segregation is becoming the governing rule; Washington is only the most prominent example of a city which has become overwhelmingly Negro as whites move to the suburbs; many other cities are moving along the same road — for example, Chicago, which, if present trends continue, will be over 50 percent Negro by 1975. The ghettoes of Harlem and Southside and Watts are cities in themselves, areas of as much as 350, 000 people. Poverty and unemployment are endemic: from one-third of the families in these areas live in poverty, in some, male unemployment may be as high as 40 percent; unemployment of Negro youths nationally is over 25 percent. Welfare and dependency are pervasive: one-fourth of the children in these ghettoes, as in Harlem, may receive Federal Aid to Dependent Children; in New York City, ADC alone costs over $ 20 million a month; in our five largest cities, the ADC bill's over $ 500 million a year.Housing is overcrowded, unhealthy, and dilapidated: the last housing census found 43 percent of urban Negro housing to be substandard; in these ghettoes, over 10, 000 children may be injured or infected by rat bites every year. Education is segregated, unequal, and inadequate: the high school dropout rate averages nearly 70 percent, there are academic high schools in which less than 3 percent of the entering students will graduate with an academic diploma. Health is poor and care inadequate: infant mortality in the ghettoes is more than twice the rate outside, mental retardation among Negroes caused by inadequate prenatal care is more than seven times the white rate; one-half of all babies born in Manhattan last year will have had no prenatal care at all; deaths from diseases like tuberculosis, influenza, and pneumonia are two to three times as common as elsewhere. [9] Fifth is both cause and consequence of all the rest. It is the destruction of the sense, and often the fact, of community, of human dialog, the thousand invisible strands of common experience and purpose, affection and respect which tie men to their fellows. Community is expressed in such words as neighborhood, civic pride, friendship. It provides the life-sustaining force of human warmth and security, a sense of one's own human significance in the accepted association and companionship of others. [10] ...Community demands a place where people can see and know each other, where children can play and adults work together and join in the pleasures and responsibilities of the place where they live. The whole history of the human race, until today, has been the history of community. Yet, this is disappearing, and disappearing at a time when its sustaining strength is badly needed. For other values which once gave strength for the daily battle of life are also being eroded. [11] The widening gap between the experience of the generations in a rapidly changing world has weakened the ties of family; children grow up in a world of experience and culture their parents never knew. [12] The world beyond the neighborhood has become more impersonal and abstract. Industry and great cities, conflicts between nations and the conquests of science move relentlessly forward, seemingly beyond the reach of individual control or even understanding. [13] ...But of all our problems, the most immediate and pressing, the one which threatens to paralyze our very capacity to act, to obliterate our vision of the future, is the plight of the Negro of the center city. For this plight and the riots which are its product and symptom — threaten to divide Americans for generations to come; to add to the ever-present difficulties of race and class the bitter legacy of violence and destruction and fear.... [14] It is therefore of the utmost importance that these hearings go beyond the temporary measures thus far adopted to deal with riots — beyond the first hoses and the billy clubs; and beyond even sprinklers on fire hydrants and new swimming pools as well. These hearings must start us along the road toward solutions to the underlying conditions which afflict our cities, so that they may become the places of fulfillment and ease, comfort and joy, the communities they were meant to be.
