18、es)Directions: There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single li
19、ne through the centre.Passage OneQuestions 21 to 25 are based on the following passage.In the 1920s demand for American farm products fell, as European countries began to recover from World War I and instituted austerity (紧缩) programs to reduce their imports. The result was a sharp drop in farm pric
20、es. This period was more disastrous for farmers than earlier times had been, because farmers were no longer self-sufficient. They were paying for machinery, seed, and fertilizer, and they were also buying consumer goods. The prices of the items farmers bought remained constant, while prices they rec
21、eived for their products fell. These developments were made worse by the Great Depression, which began in 1929 and extended throughout the 1939s.In 1929, under President Herbert Hoover, the Federal Farm Board was organized. It established the principle of direct interference with supply and demand,
22、and it represented the first national commitment to provide greater economic stability for farmers.President Hoovers successor attached even more importance to this problem. One of the first measures proposed by President Franklin D. Roosevelt when he took office in 1933 was the Agricultural Adjustm
23、ent Act, which was subsequently passed by Congress. This law gave the Secretary of Agriculture the power to reduce production through voluntary agreements with farmers who were paid to take their land out of use. A deliberate scarcity of farm products was planned in an effort to raise prices. This l
24、aw was declared unconstitutional by the Supreme Court on the grounds that general taxes were being collected to pay one special group of people. However, new laws were passed immediately that achieved the same result of resting soil and providing flood-control measures, but which were based on the p
25、rinciple of soil conservation. The Roosevelt Administration believed that rebuilding the nations soil was in the national interest and was not simply a plan to help farmers at the expense of other citizens. Later the government guaranteed loans to farmers so that they could buy farm machinery, hybri
26、d (杂交) grain, and fertilizers.21. What brought about the decline in the demand for American farm products?A) The impact of the Great Depression.B) The shrinking of overseas markets.C) The destruction caused by the First World War.D) The increased exports of European countries.22. The chief concern o
27、f the American government in the area of agriculture in the 1920s was _.A) to increase farm productionB) to establish agricultural lawsC) to prevent farmers from going bankruptD) to promote the mechanization of agriculture23. The Agricultural Adjustment Act encouraged American farmers to _.A) reduce
28、 their scale of productionB) make full use of their landC) adjust the prices of their farm productsD) be self-sufficient in agricultural production24. The Supreme Court rejected the Agricultural Adjustment Act because it believed that the Act _.A) might cause greater scarcity of farm productsB) didn
29、t give the Secretary of Agriculture enough powerC) would benefit neither the government nor the farmersD) benefited one group of citizens at the expense of others25. It was claimed that the new laws passed during the Roosevelt Administration were aimed at _.A) reducing the cost of farmingB) conservi
30、ng soil in the long-term interest of the nationC) lowering the burden of farmersD) helping farmers without shifting the burden onto other taxpayersPassage TwoQuestions 26 to 30 are based on the following passage.In the 1950s, the pioneers of artificial intelligence (AI) predicted that, by the end of
31、 this century, computers would be conversing with us at work and robots would be performing our housework. But as useful as computers are, theyre nowhere close to achieving anything remotely resembling these early aspirations for humanlike behavior. Never mind something as complex as conversation: t
32、he most powerful computers struggle to reliably recognize the shape of an object, the most elementary of tasks for a ten-month-old kid.A growing group of AI researchers think they know where the field went wrong. The problem, the scientists say, is that AI has been trying to separate the highest, mo
33、st abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step programs. A new movement in AI, on the other hand, takes a closer look at the more roundabout way in which nature came up with intelligence. Many of these researchers study evolution and na
34、tural adaptation instead of formal logic and conventional computer programs. Rather than digital computers and transistors, some want to work with brain cells and proteins. The results of these early efforts are as promising as they are peculiar, and the new nature-based AI movement is slowly but su
35、rely moving to the forefront of the field.Imitating the brains neural (神经的) network is a huge step in the right direction, says computer scientist and biophysicist Michael Conrad, but it still misses an important aspect of natural intelligence. “People tend to treat the brain as if it were made up o
36、f color-coded transistors”, he explains, “but its not simply a clever network of switches. There are lots of important things going on inside the brain cells themselves.” Specifically, Conrad believes that many of the brains capabilities stem from the pattern recognition proficiency of the individua
37、l molecules that make up each brain cell. The best way to build and artificially intelligent device, he claims, would be to build it around the same sort of molecular skills.Right now, the option that conventional computers and software are fundamentally incapable of matching the processes that take
38、 place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow AI rebels could turn out to be the only game in town.26. The author says that the powerful computers of today _.A) are capable of reliably recognizing the shape of an objectB) are close to exh
39、ibiting humanlike behaviorC) are not very different in their performance from those of the 50sD) still cannot communicate with people in a human language27. The new trend in artificial intelligence research stems from _.A) the shift of the focus of study on to the recognition of the shapes of object
40、sB) the belief that human intelligence cannot be duplicated with logical, step-by-step programsC) the aspirations of scientists to duplicate the intelligence of a ten-month-old childD) the efforts made by scientists in the study of the similarities between transistors and brain cells28. Conrad and h
41、is group of AI researchers have been making enormous efforts to _.A) find a roundabout way to design powerful computersB) build a computer using a clever network of switchesC) find out how intelligence developed in natureD) separate the highest and most abstract levels of thought29. Whats the author
42、s opinion about the new AI movement?A) It has created a sensation among artificial intelligence researchers but will soon die out.B) Its a breakthrough in duplicating human thought processes.C) Its more like a peculiar game rather than a real scientific effort.D) It may prove to be in the right dire
43、ction though nobody is sure of its future prospects.30. Which of the following is closest in meaning to the phrase “the only game in town” (Line 3, Para. 4)?A) The only approach to building an artificially intelligent computer.B) The only way for them to win a prize in artificial intelligence resear
44、ch.C) The only area worth studying in computer science.D) The only game they would like to play in town.Passage ThreeQuestions 31 to 35 are based on the following passage:Cars account for half the oil consumed in the U.S., about half the urban pollution and one fourth the greenhouse (温室) gases. They
45、 take a similar toll of (损耗) resources in other industrial nations and in the cities of the developing world. As vehicle use continues to increase in the coming decade, the U.S. and other countries will have to deal with these issues or else face unacceptable economic, health-related and political c
46、osts. It is unlikely that oil prices will remain at their current low level or that other nations will accept a large and growing U.S. contribution to global climatic change.Policymakers and industry have four options: reduce vehicle use, increase the efficiency and reduce the emissions of conventio
47、nal gasoline-powered vehicles, switch to less harmful fuels, or find less polluting driving systems. The last of thesein particular the introduction of vehicles powered by electricityis ultimately the only sustainable option. The other alternatives are attractive in theory but in practice are either
48、 impractical or offer only marginal improvements. For example, reduced vehicle use could solve traffic problems and a host of social and environmental problems, but evidence from around the world suggests that it is very difficult to make people give up their cars to any significant extent. In the U
49、.S., mass-transit ridership and carpooling (合伙用车) have declined since World War II. Even in Western Europe, with fuel prices averaging more than $1 a liter (about $4 a gallon) and with easily accessible mass transit and dense populations, cars still account for 80 percent of all passenger travel.Improved energy efficiency is also appealing, but automotive fuel economy has barely made any progress in 10 years. Alternative fuels such as natural gas, burned in internal-combustion engines, could be introduced at re
