1、英语-阅读理解(九)及答案解析(总分:100.00,做题时间:90 分钟)一、Reading Comprehensio(总题数:0,分数:0.00)二、Passage 1(总题数:1,分数:20.00)In the 1950s, the pioneers of artificial intelligence (AI) predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our housework. But
2、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: the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of tasks
3、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, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step
4、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 natural adaptation instead of formal logic and conventional computer programs. Rather than digital computers and
5、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 surely moving to the forefront of the field.Imitating the brains neural (神经的) network is a huge step in the fight
6、 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 of color-coded transistors,“ he explains. “But its not simply a clever network of switches. There are lots of im
7、portant 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 individual molecules that make up each brain cell. The best way to build an artificially intelligent device, he claims,
8、would be to build it around the same sort of molecular skills.Right now, the notion that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow AI r
9、ebels could turn out to be the only game in town.(分数:20.00)(1).The author says that the powerful computers of today _.A. are capable of reliably recognizing the shape of an objectB. are close to exhibiting humanlike behaviorC. are not very different in their performance from those of the 1950sD. sti
10、ll cannot communicate with people in a human language(分数:4.00)A.B.C.D.(2).The new trend in artificial intelligence research stems from _.A. the shift of the focus of study to the recognition of the shapes of objectsB. the belief that human intelligence cannot be duplicated with logical, step-by-step
11、 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 cells(分数:4.00)A.B.C.D.(3).Conrad and his group of AI researchers have been making enormous efforts to _.A.
12、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 thought(分数:4.00)A.B.C.D.(4).Whats the authors opinion about the new AI movement?A. It has create
13、d 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 direction though nobody is sure of its futureprospects.(
14、分数:4.00)A.B.C.D.(5).Which of the following is closest in meaning to the phrase “the only game in town“?A. The only approach to building an artificially intelligent computer.B. The only way for them to win a prize in artificial intelligence research.C. The only area worth studying in computer science
15、.D. The only game they would like to play in town.(分数:4.00)A.B.C.D.三、Passage 2(总题数:1,分数:20.00)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 take a similar toll of (损耗) resources in other industrial nations and in th
16、e 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 costs. It is unlikely that prices will remain at their current low level or t
17、hat 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 conventional gasoline-powered vehicles, switch to less harmful fuels, or find less pollut
18、ing 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 impractical or offer only marginal improvements. For example, reduced vehicle u
19、se 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.S. , mass-transit ridership and carpooling (合伙用车) have declined since World War
20、 . 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 m
21、ade any progress in 10 years. Alternative fuels such as natural gas, burned in internal-combustion engines, could be introduced at relatively low cost, but they would lead to only marginal reductions in pollution and greenhouse emissions (especially because oil companies are already spending billion
22、s of dollars every year to develop less polluting types of gasoline).(分数:20.00)(1).From the passage we know that the increased use of cars will _.A. consume half of the oil produced in the worldB. have serious consequences for the well-being of all nationsC. widen the gap between the developed and d
23、eveloping countriesD. impose an intolerable economic burden on residents of large cities(分数:4.00)A.B.C.D.(2).The U.S. has to deal with the problems arising from vehicle use because _.A. most Americans are reluctant to switch to public transportation systemsB. the present level of oil prices is consi
24、dered unacceptableC. other countries will protest its increasing greenhouse emissionsD. it should take a lead in conserving natural resources(分数:4.00)A.B.C.D.(3).Which of the following is the best solution to the problems mentioned in the passage?A. The designing of highly efficient car engines.B. A
