A) find a roundabout way to design powerful puters B) build a puter using a clever work of switches C) find out how intelligence developed in nature D) separate the highest and most abstract levels of thought 39。 s the author39。 s opinion about the new AI movement?

C) It39。 s more like a peculiar game rather than a real scientific effort. D) It may prove to be in the right direction though nobody is sure of its future prospects. 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 puter. B) The only way for them to win a prize in artificial intelligence research. C) The only area worth studying in puter science.

Passage Three Question 31 to 35 are based on the following passage: Cars account for half the oil consumed in the ., about half the urban pollution and one fourth the greenhouse (温室 ) gases. They take a similar oll of (损耗 ) resources in other industrial nations and in the cities of the developing world . As vehicle use continues to increase in the ing decade, the . and other countries will have to deal with these issues or else face unacceptable economic , healthrelated and political costs. It is unlikely that oil prices will remain at their current low level or that other nations will accept a large and growing . contribution to global climatic change. Policymakers and industry have four options: reduce vehicle use, increase the efficiency and reduce the emissions of conventional gasolinepowered vehicles, switch to less harmful fuels, or find less polluting driving systems. The last of thesein particular the introduction of vehicles powered by electricity — is ultimately the only sustainable option. The other alternatives are attractive in theory but in practice are either 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 t hat it is very difficult to make people give up their cars to any significant ex tent. In the ., masstransit ridership and carpooling (合伙用车） have decline d 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 internalbustion engines, could be introduced at relatively low cost, but they would lead to only marginal reductions in pollution and greenhouse emissions (especially because oil panies are already spending billions of dollars every year to develop less polluting types of gasoline). the passage we know that the increased use of cars will ______. A) consume half of the oil produced in the world B) have serious consequences for the wellbeing of all nations C) widen the gap between the developed and developing countries D) impose an intolerable economic burden on residents of large cities . has to deal with the problems arising from vehicle use because ______. A. most Americans are reluctant to switch to public transportation systems B) the present level of oil prices is considered unacceptable C) other countries will protest its increasing greenhouse emissions D) it should take a lead in conserving natural resources of the following is the best solution to the problems mentioned in the passage? A) The designing of highly efficient car engines. B) A reduction of vehicle use in cities. C) The development of electric cars. D) The use of less polluting fuels. of the following is practical but only makes a marginal contribution to solving the problem of greenhouse emissions? A) The use of fuels other than gasoline. B) Improved energy efficiency. C) The introduction of less polluting driving systems. D) Reducing car use by carpooling of the following statements is TRUE according to the passage? A) The decline of public transportation accounts for increased car use in western Europe. B) Cars are popular in western Europe even though fuel prices are fairly high. C) The reduction of vehicle use is the only sustainable option in densely populated western Europe. D) Western European oil panies cannot sustain the cost of developing newtype fuels. Passage Four Questions 36 to 40 are based on the following passage: Reebok executives do not like to hear their stylish athletic shoes called “ footwear for yuppies ( 雅皮士，少壮高薪职业人士 )”. They contend that Reebok shoes appeal to diverse market segments, especially now that the pany offers basketball and children39。 s shoes for the under18 set and walking shoes for older customers not interested i。
