The city of Singapore, the capital of the country, is at the southeastern end of the Singapore Island; it is one of the most important port cities and commercial centers of Southeast Asia. The total area of the republic is 640 sq kmLow-lying Singapore Island has no outstanding relief(轮廓鲜明的) features. A central area of hills rises to the maximum height of 176 m. The country has a wet tropical climate, with an average annual temperature of 27.20℃. The average annual rainfall is 2.413 mm. the wettest months are November through January.Singapore is governed under a constitution of 1959. A president, elected to a four-year term, is head of state, and a prime minister is head of government. The president used to be selected by Parliament, but by 1991 constitutional amendment（修正案）, the president is now elected directly by the people. The Parliament is the law-making body with its 81 members popularly elected.【*】In the late 1980s the country had some 290 primary schools with 278,300 pupils and 160 secondary schools with 200,200 students. The main institutions of higher education are the National University of Singapore, several technical colleges, and a teachers college.【*】Singapore has one of the highest standards of living of any country in Asia. In the late 1980s the gross domestic product was estimated at $23.7 billion, or $8, 870 per person. The fishing industry is centered on the port of During, on southwestern Singapore Island. Industry has grown rapidly since the 1960s, and Singapore now produces a diversity of goods, including chemicals, electronic items, clothing, and processed foods, etc. Shipbuilding and petroleum refining are also important.1【单选】Paragraph 1（）AEducationBLand and ClimateCState SystemDGeneral IntroductionEEconomyFPopulation

- 材料全屏 Job or Money【*】Would you quit your job if you didn't need the money? In a 1990 poll by the Gallop Organization, many people said quitting work was an important reason to be rich. Yet researchers find that work is one of life's chief satisfactions for people.【*】Consider W. Berry Fowler. In 1979, Fowler started a tutoring company that became so successful he was able to sell out and retire in 1978----a multimillionaire at 40. He bought a 50-foot cabin cruiser and a house in Hawaii, and busied himself vacationing.【*】But after five years of perpetual vacation, Fowler began to miss the challenges of work. So in 1992, he bought a fitness chain for children and now spends 75 hours a week immersed in balance sheets and staff meetings."My best days on the golf course weren't half as much fun as a good day at the office, he says.【*】A job, studies show, is more than a paycheck. Doing something well can increase confidence and self-worth. When sociologist H. Ray Kaplan surveyed 139 lottery millionaires, he discovered 60 percent continued working at least a year after they’d won.【*】If jobs are so important, wouldn't salary size be a gauge of job satisfaction? Americans think so. A survey conducted last year by Roper Starch Worldwide, Inc. , found that almost 70 percent of the respondents said they would be happier if their families had twice as much household income. Yet studies show that job satisfaction comes less from how much people earn than from the challenge of their jobs and the control they are able to exert. Work that doesn't engage a person will never seem rewarding, no matter how lucrative it becomes.1【单选】The Gallop poll shows many people want to be rich in order not to work.（）A RightBWrongCNot mentioned
- Researchers did another survey after the Gallop poll.（）ARightBWrongCNot mentioned

- 材料全屏 Soot(烟灰) and Snow: a Hot Combination【*】New research from NASA scientists suggests emissions (释放) of black soot alter the way sunlight reflects off snow. According to a computer simulation(模拟), black soot may be responsible for 25 percent of observed global warming over the past century.【*】Soot in the higher latitudes(纬度) of the Earth, where ice is more common, absorbs more of the sun s energy and warmth than an icy, white background. Dark-colored black carbon, or soot, absorbs sunlight, while lighter colored ice reflects sunlight【*】Soot in areas with snow and ice may play an important role in climate change. Also, if snow and ice covered areas begin melting, the warming effect increases, as the soot becomes more concentrated on the snow surface. This provides a positive feedback, as glaciers and ice sheet smelt, they tend to get even dirtier,"said Dr.James Hansen, a researcher at NASA's Goddard Institute for Space Studies, New York.【*】Hansen found soot's effect on snow albedo(反照率)( solar energy reflected back to space), which may be contributing to trends toward early springs in the Northern Hemisphere, such as thinning Arctic sea ice, melting glaciers and permafrost(永冻层). Soot also is believed to play a role in changes in the atmosphere above the oceans and land.【*】"Black carbon reduces the amount of energy reflected by snow back into space, thus heating the snow surface more than if there were no black carbon,"Hansen said. Soot's increased absorption of solar energy is especially effective in warming the world’s climate."This forcing is unusually effective, causing twice as much global warming as a carbon-dioxide(二氧化碳) forcing of the same magnitude(量,大小),” Hansen noted.【*】Hansen cautioned, although the role of soot in altering global climate is substantial, it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century. Such gases are expected to be the largest climate forcing for the rest of this century.【*】The researchers found that observed warming in the Northern Hemisphere was large in the winter and spring at middle and high latitudes. These observations were consistent with the researchers' elimate model simulations, which showed some of the largest warming effects occurred when there were heavy snow cover and sufficient sunlight.1【单选】Paragraph①_____ASoot's Role in Climate Changes Above Oceans and LandBObservations of Warming in the Northern HemisphereCExplanation of Increased Warming Effect Caused by SootDBlack Soot in Snow and Icy Areas Leading to Climate ChangeEBlack Soot Contributing to Global WarmingFGreenhouse Gases as the Main Factor of Global Warming
