21、. Technology is costly and it is generally impossible to introduce advances to everyone at the same time. So who gets this access first? As we travel further and further along the electronic frontier through advances such as telecommuting (在家办公) and the Internet, the poor may be isolated from mainst

22、ream society in an “ information ghetto (贫民窟) Drawing on a survey, the Census Bureau(国家调查局) estimated that only 6.8 percent of households earning less than $ 10,000 had home computers, compared to 61.7 percent of those with incomes of $ 75,000 or more. This issue goes beyond individual interest or l

23、ack of interest in computers. The technological advances of the present and future may not be equally beneficial to men and women. Many studies have shown that computer games, which serve as an important means of early socialization to computers, typically involve sports or skills associated with th

24、e traditional male role. As a result computers camps have become mainly male settings. Like money, food, and other resources, technology is unevenly distributed within societies and throughout the world. The technology gap is widening rather than narrowing. Although nations are exchanging technical

25、data more freely than before, critical technology transfer is often kept back. The technology exported to developing countries may be poorly suited to the conditions of their economies and workplaces.（分数：10.00）(1).According to the writer, “information ghetto“ is caused by_.（分数：2.00）A.the strict cont

29、ntriesD.keeping back the exporting countries economy(5).The writer s attitude towards the development of technology is_.（分数：2.00）A.negativeB.indifferentC.exciting and praisingD.concerned and critical27.Task 2Directions：This task is the same as Task 1The 5 questions or unfinished statements are numbe

30、red 41 through 45_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 cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward a

31、t such a pace we can be less sure. Quite soon, in only 10 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 (软件) or by altering the architecture bu

32、t that too will happen. I think it is certain that in decades, not centuries, machines of silicon (硅) will arise first to rival and then exceed 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

33、 have ended carbons 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

34、 on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds 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

35、, home to thousands or millions of people, will be within our power.（分数：10.00）(1).In what way can we make a machine intelligent?（分数：2.00）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 struc

36、ture.D.By reproducing it.(2).What does the writer think about machines with human-like ability?（分数：2.00）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 construct

37、ion of such machines possible.(3).The word “carbon“ (Line 3, Para. 2)stands for_.（分数：2.00）A.intelligent robotsB.a chemical elementC.an organic substanceD.human beings(4).A robot can be used to expand our frontiers when_.（分数：2.00）A.its intelligence and cost are beyond questionB.it is able to bear the

38、 rough environmentC.it is made as complex as the human brainD.its architecture is different from that of the present ones(5).It can be inferred from the passage that_.（分数：2.00）A.after the installation of a great number of cells and connections, robots will be capable of self-reproductionB.with the r

41、r, doctors have begun to investigate laughter and the effects it has on the human body. They have found evidence that laughter really can improve peoples health. Tests were carried out to study the effects of laughter on the body. People watched funny films, while doctors checked their heart rate, b

42、lood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it mu

43、st be beneficial. Other tests have shown that laughter appears to be capable of reducing the effect of pain on the body. There is also some evidence to suggest that laughter helps the bodys immune system, that is, the system which fights infection. As a result of these discoveries, some doctors and

44、psychiatrists (精神病学家)in the United States now hold laughter clinics, in which they try to improve their patients condition by encouraging them to laugh. 1) Laughter really can 1 . 2)In the first test, it was found that laughter has similar effects to 2 . 3) Other tests have shown that laughter can reduce the effect of 3 on the body. 4) There is evidence to show that laughter helps the body s 4 . 5) In the clinics, the psychiatrists try to improve their patients condition by encouraging them 5 .（分数：10.00）填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_30.Task 4Directions：T
