2、 industry are aware of this wider possibility and are planning sizable wind-farm projects in states other than California. 有些能源行业的公司意识到了这个更大的可能性，正在计划在美国除了加州以外的州建立大型的风力发电站项目。 Since 1980, the use of wind to produce electricity has been growing rapidly. In 1994 there were nearly 20,000 wind turbines wo

3、rldwide, most grouped in clusters called wind farms that collectively produced 3,000 megawatts of electricity. Most were in Denmark (which got 3 percent of its electricity from wind turbines) and California (where 17,000 machines produced 1 percent of the states electricity, enough to meet the resid

4、ential needs of a city as large as San Francisco). In principle, all the power needs of the United States could be provided by exploiting the wind potential of just three statesNorth Dakota, South Dakota, and Texas.

6、antyMost people remember only a few events-usually ones that were meaningful and distinctive，such as being hospitalized or a siblings birth. Look at the four squares that indicate where the following sentence could be added to the passage. Other important occasions are school graduations and wedding

7、s. Cases in which many species become extinct within a geologically short interval of time are called mass extinctions. There was one such event at the end of the Cretaceous period (around 70 million years ago). There was another, even larger, mass extinction at the end of the Permian period (around

8、 250 million years ago). The Permian event has attracted much less attention than other mass extinctions because mostly unfamiliar species perished at that time. Look at the four squares that indicate where the following sentence could be added to the passage. In general, it is believed that these t

9、wo extinctions resulted from drastic environmental changes that followed meteorite impacts or massive volcanic eruptions. Accordingly, France set out to overcome Britain by extending its military domination from Moscow to Lisbon, from Jutland to Calabria. All of this entailed tremendous risk, becaus

10、e France did not have the military resources to control this much territory and still protect itself and maintain order at home. French strategists calculated that a navy of 150 ships would provide the force necessary to defeat the British navy. This advantage was deemed necessary because of Britain

11、s superior sea skills and technology, and also because Britain would be fighting a defensive war, allowing it to win with fewer forces. Such a force would give France a three-to-two advantage over Britain. Several factors affect tidal ranges, including abrupt changes in atmospheric pressure or prolo

12、nged periods of extreme high or low pressure. They are also influenced by the density and volume of seawater, variations in ocean-current velocities, earthquakes, and the growing or shrinking of the worlds glaciers. In fact, any of these factors alone can alter sea level. The greater and more rapid

13、the change of water level, the greater the erosive effect of the tidal action, and thus in the amount of material transported and deposited on the shore. Storm surges, such as the heaping up of ocean water by hurricane winds, are yet another factor. We all know that many more people today are right-

14、handed than left-handed. Can one trace this same pattern far back in prehistory? Much of the evidence about right-hand versus left-hand dominance comes from stencils and prints found in rock shelters in Australia and elsewhere, and in many Ice Age caves in France, Spain, and Tasmania. When a left ha

15、nd has been stenciled, this implies that the artist was right-handed, and vice versa. Even though the paint was often sprayed on by mouth, one can assume that the dominant hand assisted in the operation. One also has to make the assumption that hands were stenciled palm downwarda left hand stenciled

16、 palm upward might of course look as if it were a right hand. Of 158 stencils in the French cave of Gargas, 136 have been identified as left, and only 22 as right; right-handedness was therefore heavily predominant. The stencils of hands found in these shelters and caves allow us to draw conclusions

17、 about which hand was dominant.Clue 2逻辑关系 常见逻辑关系：并列、递进、转折、因果、比较 并列递进：furthermore, also, as well, too, in addition, moreover, besides, even, additionally, first, second, third., not only. but also 转折：although, conversely, however,instead, nevertheless, on the other hand, unlike, whereas, while 因果：the

19、mpting to conserve water by irrigating less frequently or by switching to crops that require less water. Other, however, have adopted the philosophy that it is best to use the water while it is still economically profitable to do so and to concentrate on high-value crops such as cotton. The incentiv

20、e of the farmers who wish to conserve water is reduced by their knowledge that many of their neighbors are profiting by using great amounts of water, and in the process are drawing down the entire regions water supplies. In the face of the upcoming water supply crisis, a number of grandiose schemes

21、have been developed to transport vast quantities of water by canal or pipeline from the Mississippi, the Missouri, or the Arkansas rivers. Unfortunately, the cost of water obtained through any of these schemes would increase pumping costs at least tenfold, making the cost of irrigated agricultural p

22、roducts from the region uncompetitive on the national and international markets. But even if uncooperative farmers were to join in the conservation efforts, this would only delay the depletion of the aquifer. The subjects of the paintings are mostly animals. The paintings rest on bare walls, with no

23、 backdrops or environmental trappings. Perhaps, like many contemporary peoples, Upper Paleolithic men and women believed that the drawing of a human image could cause death of injury, and if that were indeed their belief, it might explain why human figures are rarely depicted in cave art. Another ex

24、planation for the focus on animals might be that these people sought to improve their luck at hunting. This theory is suggested by evidence of chips in the painted figures, perhaps made by spears thrown at the drawings. But if improving their hunting luck was the chief motivation for the paintings,

25、it is difficult to explain why only a few show signs of having been speared. Perhaps the paintings were inspired by the need to increase the supply of animals. Cave art seems to have reached a peak toward the end of the Upper Paleolithic period, when the herds of game were decreasing. Therefore, if

26、the paintings were connected with hunting, some other explanation is needed.Clue 3结构关系 西方人的思维 总分结构来论证观点 总分结构本质：先论点，后论证 Fantasy is one of the more common techniques in advertising that could possibly mislead a young audience. Child-oriented advertisements are more likely to include magic and fantasy

27、than advertisements aimed at adults. In a content analysis of Canadian television, the author Stephen Kline observed that nearly all commercials for character toys featured fantasy play. Children have strong imaginations and the use of fantasy brings their ideas to life, but children may not be adep

28、t enough to realize that what they are viewing is unreal. Fantasy situations and settings are frequently used to attract childrens attention, particularly in food advertising. Advertisements for breakfast cereals have, for many years, been found to be especially fond of fantasy techniques, with almo

29、st nine out of ten including such content. Generally, there is uncertainty as to whether very young children can distinguish between fantasy and reality in advertising. Certainly, rational appeals in advertising aimed at children are limited, as most advertisements use emotional and indirect appeals

32、Sea between England and the Continentnot of vast oceans. New types of ships were needed, new methods of finding ones way, new techniques for financing so vast a scheme. The sheer scale of the investment it took to begin commercial expansion at sea reflects the immensity of the profits that such East-West trade could create. Spices were the most sought-after commodities. Spices not only dramatically improved the taste of the European diet but also were used to manufacture perfumes and certain medicines. But even hig
