单选题It remains to be seen whether the reserves of raw materials in the year 2000 will be sufficient to supply a world economy which will have grown by five hundred percent. Southeast Asia alone will have an energy consumption five times greater than that of Western Europe in 1970. Incidentally, if the underdeveloped countries started using up petrol at the same rate as the industrialized areas, then world reserves would be exhausted by 1990. All this only goes to show just how important it is to set up a plan to conserve and divide up fairly natural resources on a worldwide scale. This is a matter of life and death because world population is expanding at an incredible rate. By the middle of the next century population will expand every year by as much as it did in the first 1,500 years after Christ. In the southern, poor parts of the globe, the figures are enough to make your hair stand on end. Even supposing that steps are taken to stabilize world population in the next fifty years, the number of inhabitants per square kilometer will increase by from 4 in the United States to 140 in South East Asia. What can we do about it? In the first hypothesis we do nothing. By the year 2000, the southern parts of the world would then have a population greater than the total world population today. Alternately we could start acting right now to bring birth rate under control within fifteen years so that population levels off. Even then the population in the southern areas would not stop growing for seventy-five years. And the population would level off at something like twice today's figure. Finally, we could wait ten to twenty years before taking action. If we wait ten years the population of the southern area would stabilize at 3,000 million. Even today the number of potential workers increases by 350,000 people per week. By the end of the century this figure will reach 750,000; in other words, it will be necessary to find work for 40 million people per year--not to speak of food. What this means in practical terms we can scarcely imagine. But clearly if we do nothing, nature will solve the problem for us. But at what cost!

单选题More young Americans have become better educated. This reflects a 26 in the labor market, which has increasingly rewarded post-secondary education. At the same time, the economy has seen a decrease in well-paid manual labor that required skills learned on the job or in trade schools. The shift to a more service-oriented economy means universities and colleges have 27 trade schools and apprenticeships. On the one hand that is good because it makes the American labor force better educated. Theoretically, it should also increase meritocracy (精英教育). Much of the income. 28 in America can be explained by the earning differential between college and non-college graduates. As more people attend university, income differences should be reduced. But as university education becomes more widely 29 , should curricula change? Between labor-market demand and innate ability, probably only a fraction of the population benefit 30 from doing so. On the other hand, America 31 from title inflation. A university degree is now a prerequisite (必要条件) to middle-class membership. Rather than just being 32 of education, it is also an expensive and time-consuming signal. The high rate of entrance examination masks a grave problem. Dropping out of university is at 33 levels, especially among low-income Americans. Starting but not finishing a degree 34 in a considerable loss of time and money. Many poor students drop out not just because of cost, but because they find themselves unprepared and frustrated. Offering more practical degrees could be part of the solution to this problem, though it is not a 35 solution. A. available I. equaled B. consists J. proof C. conversely K. replaced D. decrease L. results E. delicate M. shift F. difference N. suffers G. economically O. sufficient H. epidemic

单选题When I was home in Britain on holiday last summer, I spent an evening looking at photos my father had taken when he stayed with us in Beijing in the spring of 1966. Of all these interesting scenes of the past, the one I exclaimed at was a photo of Chang An Jie at Tiananmen. The photo showed one car and two bicycles! This made me reflect on the changes that have transformed Beijing since I came to the city 37 years ago. In those days, the bicycle was king. What sheer joy it was to cycle along with the hundreds (not thousands) of fellow pedallers (骑车人), never in fear of life and limb as one is now. I bought my first bike in 1963. It cost me 150 yuan--in those days three or four months' salary for the average city dweller. Such changes! Good or bad? Today, cycling is hazardous but bikes are easily affordable. Gone are the old wooden houses I remember in south Beijing and fast disappearing are the small, overcrowded courtyard houses lacking running water, central heating and bathroom. Very many Beijingers now live in more convenient, better-equipped flats in high-rises. But these very high-rises are swallowing up the unique character of the old city of narrow hutongs, age-old siheyuan and close-knit communities. I loved years ago to cycle to Beihai to visit my friends (I then taught at China Foreign Affairs University). In spring I rode through the blue-green wheat fields, in summer through fields of tall maize (玉米). Further west; beyond Beijing Foreign Studies University there were the vegetable fields of the Evergreen Commune (四季青公社) and the rice paddies glistening in the summer sun. But now, as Beijing stretches out further and further, west, east, north, south, there's decent housing for families, busy offices for employment and large department stores and supermarkets where, if you have the money, there's little you cannot buy.
