填空题The "standard of living" of any country means the average person"s 11 of the goods and services the country produces. A country"s standard of living, therefore, depends on its capacity to produce wealth. "Wealth" in this 12 is not money, for we do not live on money but on things that money can buy: "goods" such as food and clothing, and "services" such as 13 and entertainment. A country"s capacity to produce wealth depends upon many factors, most of which have an effect on one another. Wealth depends to a great extent upon a country"s natural resources. Some regions of the world are well 14 with coal and minerals, and have fertile soil and a 15 climate; other regions possess none of them. Next to natural resources comes the ability to 16 them to use. China is perhaps as well-off as the USA in natural resources, but suffered for many years from 17 and external wars, and for this and other reasons, was unable to develop her resources. Sound and stable political conditions, and being free from foreign invasions, enable a country to develop its natural resources peacefully and steadily, and to produce more wealth than another country equally well 18 .by nature but less well ordered. A country"s standard of living does not only depend upon the wealth that is produced and consumed within its 19 , but also upon what is directly produced through international trade. For example, Britain"s wealth in food stuffs and other agricultural products would be much less if she had to depend only on those grown at home. Trade makes it possible for her 20 manufactured goods to be traded abroad for the agricultural products that would otherwise be lacking. A country"s wealth is, therefore, much influenced by its manufacturing capacity provided that other countries can be found ready to accept its manufactures. A．wealth B．sense C．supplied D．share E．surplus F．transport G．1imits H．equipped I．favorable J．turn K．put L．civil M．favored N．borders O．internal

填空题Considering how jazz is transcribed in Chinese (jueshi), you may be 11 into assuming that it is an aristocratic cultural form. Nothing could be further from the truth. It 12 among black Americans at the end of the 19th century, at a time when they occupied the very 3 of the American social heap. So how has something that was created by a once downtrodden and 13 minority acquired a central place in today"s American culture? Mr. Darrell A Jenks, director of the American Center for Educational Exchange, and also a drummer in the jazz band Window, analyses the phenomenon for us here. Jazz: the 14 of America. Perhaps the essence of America is that you could never get two Americans to agree on just what that might be. After thinking about it for a while, we might, chuckle and say, "Hmm, seems like being American is a bit more complicated than we thought." Certainly things like 15 , success (the "American Dream" ), innovation and tolerance stand out. But these things come together because of our ability to work with one another and find common purpose no matter how we might be 16 Some, like African-American writer Ralph Ellison, believe that jazz 17 the essence of America. For good reason, for in jazz all of the characteristics I mentioned above come together. The solos are a celebration of individual brilliance that can"t take place without the group efforts of the rhythm section. Beyond that, though, jazz has a connection to the essence of America in a much more fundamental 18 . It is an expression of the African 19 of American culture, a musical medium that exemplifies the culture of the Africans whose culture came to dominate much of what is American.

填空题A．principal B．lubricating C．yield D．Crude E．substitute F．collecting G．surplus H．impractical I．smelting J．gathering K．produce L．rivaled M．competed N．petroleum O．Coarse An important new industry, oil refining, grew after the Civil War. 1 oil, or petroleum, a dark, thick ooze from the earth had been known for hundreds of years, but little use had ever been made of it. In the l850s, Samuel M. Kier, a manufacturer in western Pennsylvania, began 2 the oil and refining it into kerosene. Refining, like 3 , is a process of removing impurities from a raw material. Kerosene was used to light lamps. It was a cheap 4 for whale oil, which was becoming harder to get. Soon there was a large demand for kerosene. People began to search for new supplies of 5 . The first oil well was drilled by E. L. Drake, a retired railroad conductor. In 1859 he began drilling in Titusville, Pennsylvania. The whole venture of drilling seemed so 6 and foolish that onlookers called it "Drake"s Folly". But when he had drilled down about 70 feet (21 meters), Drake struck oil. His well began to 7 20 barrels of crude oil a day. News of Drake"s success brought oil prospectors to the scene. By the early 1860s these wildcatters were drilling for "black gold" all over western Pennsylvania. The boom 8 the California gold rush of 1848 in its excitement and Wild West atmosphere. And it brought far more wealth to the prospectors than any gold rush. Petroleum could be refined into many products. For some years kerosene continued to be the 9 one. It was sold in grocery stores and door-to-door. In the 1880s and 1890s refiners learned how to make other petroleum products such as waxes and 10 oil. Petroleum was not then used to make gasoline or heating oil.

However The warming of the Earth observed over the last 100 years is due to a combination of many factors. Warming due to the increase in greenhouse gases 31 has been the determining factor so far. 32 , projections of greenhouse warming do not rest on recent observations; they come from scientific understanding of the climate system. A 33 of simple and complex computer models has been used over the last 30 years to put together knowledge of many climate processes. Contrary to some scientific opinion, current models do a reasonable job of simulating today"s climate. The difference between summer and winter temperatures, in 34 to change in heating from the Sun, is correctly simulated to 35 about 0.5 degrees over much of the planet. Natural events provide additional tests of our understanding. For example, the scale and 36 of cooling due to the eruption of Mt. Pinatubo were 37 by climate models. When greenhouse gases are increased in climate models, the response is always an increase in average temperatures and water vapor. Models vary in their results but, in virtually all cases, doubling the amount of carbon dioxide increases global average temperatures 38 between 1.5℃ and 4℃. Why are there some dissenting 39 heard on the science of climate change? 40 it appears that critics are simply unaware of the depth of the science developed so far. Others are concerned because we do not understand everything about the climate system.

填空题Almost every new innovation goes through three phases. When 21 introduced into the market, the process of 22 is slow. The early models are expensive and hard to use, and perhaps even unsafe. The economic 23 is relatively small. The second phase is the explosive one, 24 the innovation is rapidly adopted by a large number of people. It gets cheaper and easier to use and becomes something familiar. And then in the third stage, diffusion of the innovation slows down again, as it permeates out across the economy. During the explosive phase, whole new industries spring up to produce the new product or innovation, and to 25 it. For example, during the 1920s, there was a dramatic acceleration in auto production, from 1.9 million in 1920 to 4.5 million in 1929. This 26 was accompanied by all sorts of other essential activities necessary for an auto-based nation: Roads had to be built for the cars to run 27 ; refineries and oil wells, to provide the gasoline; and garages, to repair them. The same pattern is 28 repeated again and again with innovations. The construction of the electrical system required an enormous early investment in generation and distribution 29 . The introduction of the radio was followed by a buying spree (无节制的狂热行为) by Americans that quickly brought radios into almost half of all household by 1930, up from 30 none in 1924.
