2013高考英语二轮阅读理解（四月）训练（7）及答案
The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and ease us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only l0 or 20 years, perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software or by altering the architecture but that too will happen.
I think it certain that in decades, not centuries, machines of silicon(硅) will arise first to rival and then exceed（超越） their human ancestors. Once they exceed us they will be capable of their own design in a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.
As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.
46. In what way can we make a machine intelligent?
A. By making it work in such environments as deserts, oceans or space.
B. By working hard for 10 or 20 years.
C. By either properly programming it or changing its structure.
D. By reproducing it.
47. What does the writer think about machines with human-like ability?
A. He believes they will be useful to human beings.
B. He believes that they will control us in the future.
C. He is not quite sure in what way they may influence us
D. He doesn't consider the construction of such machines possible.
48. The underlined word“carbon”in Para. 2 stands for .
….A. intelligent robots B. a chemical element
C. an organic substance D. human beings
49. A robot can be used to expand our frontiers when .
A. its intelligence and cost are beyond question
B. it is able to bear the rough environment
C. it is made as complex as the human brain
D. its architecture is different from that of the present ones
50. It can be inferred from the passage that .
A. after the installation of a great number of cells and connections, robots will be capable of self-reproduction.
B. with the rapid development of technology, people have come to realize the possibility of making a machine with human-like ability
C. once we make a machine as complex as the human brain. it will possess intelligence
D. robots will have control of the vast, man-made world in space

例2（2012陕西卷） What brings a nation together? Of the four choices—shared values, language, history, and religion, it's shared values. In our latest poll seven out of 16 countries chose values as the greatest factor bringing a nation together, and six preferred language. Both choices scored high in the poll, suggesting that our values and how we express them are closely linked. Still, history was not forgotten in some countries, particularly in Mexico and Russia. Even Canada and the United States chose national histories as the second-most important factor uniting their people. The biggest surprise? Not one country picked religion as its top choice.
Respect your elders
In most countries, the oldest generation considered values more important to a nation than did those who are under 45 years old.
Do you speak Canadian?
Language scored lower in Canada than in all other countries polled, perhaps because the country speaks two official languages, French and English.
Church and state
Most people polled do not connect their religious beliefs to their national pride. Religion ranked last in 13 countries—with Prance scoring it at 1 %, the lowest of all.
46 According to the poll, what was the most important factor in bringing a nation together? A. Language. R Values. C History. D. Religion.
[点拨] B 短文第1段提到“In our latest poll seven out of 16 countries chose values as the greatest factor bringing a nation together, and six preferred language.”。由此不难判断，B选项符合题意。因此，正确答案为B选项。
48.According to the charts, shared values and language were considered equally important in____
A. Australia B. Brazil C. China D. India
[点拨] D 对照共同价值观和语言这两个图表，会判断发现这两个图表的最下一栏是印度。由此可知，在印度，共同价值观和语言被认为同等重要，因此，正确答案为D选项。
[小试牛刀]
C
After the violent earthquake that shook Los Angeles in 1904, earthquake scientists had good news to report: The damage and death toll(死亡人数)could have been much worse.
More than 60 people died in this earthquake. By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25, 000 victims.
Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a.m. on a holiday, when traffic was light on the city's highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes.
Despite the good news, civil engineers aren't resting on their successes. Pinned to their drawing boards are blueprints (蓝图) for improved quake-resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place.
In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports. Called smart buildings, the structures respond like living organisms to an earthquake's vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction.
The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.
51. One reason why the loss of lives in the Los Angeles earthquake was comparatively low is that .
A. new computers had been installed in the buildings
B. it occurred in the residential areas rather than on the highways
C. large numbers of Los Angeles residents had gone for a holiday
D. improvements had been made in the construction of buildings and highways
52. The function of the computer mentioned in the passage is to .
A. counterbalance an earthquake’s action on the building.
B. predict the coming of an earthquake with accuracy.
C. help strengthen the foundation of the building.
D. measure the impact of an earthquake’s vibrations.
53. The smart buildings discussed in the passage .
A. would cause serious financial problems.
B. would be worthwhile though costly.
C. would increase the complexity of architectural design.
D. can reduce the ground vibrations caused by earthquakes.
54. It can be inferred from the passage that in minimizing the damage caused by earthquakes attention should be focused on .
A. the increasing use of rubber and steel in capital construction
B. the development of flexible building materials
C. the reduction of the impact of ground vibrations
D. early forecasts of earthquakes
55. The author's main purpose in writing the passage is to__________.
A. compare the consequences of the earthquakes that occurred in the U.S.
B. encourage civil engineers to make more extensive use of computers
C. outline the history of the development of quake-resistant building materials
D. report new developments in constructing quake-resistant buildings
