单选题Too much caution in the use of computers will ______ .A prevent the solution of economic problemsB cause more suppression of human freedomC lead to clumsy methods of protectionD interfere with our study of society.

Early in the age of affluence that followed World War II,an American retailing analyst named Victor Lebow proclaimed,
“Our enormously productive economy...demands that we make consumption our way of life,that we convert the buying and
use of Eoods into rituals,that we seek our spiritual satisfaction,our ego satisfaction,in consumption...We need things
consumed,burned up,worn out,replaced and discarded at an ever increasing rate.”
Americans have responded to Lebow’s call,and much of the world has followed.Consumption has become a central pillar of life in industrial lands and is even embedded in social values.
Opinion surveys in the world’s two largest economies-Japan and the United States-show consumerist definitions of
success becoming ever more prevalent.
Overconsumption by the world’s fortunate is an environmental problem unmatched in severity by anything but perhaps
population growth.Their surging exploitation of resources threatens to exhaust or unalterably spoil forests,soils,water,air and climate.
Ironically,high consumption may be a mixed blessing in human terms,too.The time-honored values of integrity of
character,good work,friendship,family and community have often been sacrificed in the rush to riches.Thus many in the
industrial lands have a sense that their world,of plenty is somehow hollow-that,misled by a consumerist culture,they have
been fruitlessly attempting to satisfy what are essentially social,psychological and spiritual needs with material things.
Of course,the opposite of overconsumption-poverty-is no solution to either environmental or human problems.It is infinitely worse for people and bad for the natural world too.Dispossessed peasants slash-and-burn their way into the rain forests of
Latin American,and hungry nomads turn their herds out onto fragile African grassland,reducing it to desert.If environmental
destruction results when people have either too little or too much,we are left to wonder how much is enough.What level of
consumption can the earth support When does having more cease to add noticeably to human satisfaction

According to the passage,consumerist culture________.《》（）

A.cannot thrive on a fragile economy
B.will not aggravate environmental problems
C.cannot satisfy human spiritual needs
D.will not alleviate poverty in wealthy countries

To live in the United States today is to gain an appreciation for Dahrendorf′s assertion that social change exists everywhere. Technology, the application of knowledge for practical ends, is a major source of social change.
Yet we would do well to remind ourselves that technology is a human creation; it does not exist naturally. A spear or a robot is as much a cultural as a physical object. Until humans use a spear to hunt game or a robot to produce machine parts, neither is much more than a solid mass of matter. For a bird looking for an object on which to rest, a spear or robot serves the purpose equally well. The explosion of the Challenger space shuttle and the Russian nuclear accident at Chernobyl drive home the human quality of technology; they provide cases in which well-planned systems suddenly went haywire and there was no ready hand to set them right. Since technology is a human creation, we are responsible for what is done with it. Pessimists worry that we will use our technology eventually to blow our world and ourselves to pieces. But they have been saying this for decades, and so far we have managed to survive and even flourish. Whether we will continue to do so in the years ahead remains uncertain. Clearly, the impact of technology on our lives deserves a closer examination.
Few technological developments have had a greater impact on our lives than the computer revolution. Scientists and engineers have designed specialized machines that can do the tasks that once only people could do. There are those who assert that the switch to an information-based economy is in the same camp as other great historical milestones, particularly the Industrial Revolution. Yet when we ask why the Industrial Revolution was a revolution, we find that it was not the machines. The primary reason why it was revolutionary is that it led to great social change. It gave rise to mass production and, through mass production, to a society in which wealth was not confined to the few.
In somewhat similar fashion, computers promise to revolutionize the structure of American life, particularly as they free the human mind and open new possibilities in knowledge and communication. The Industrial Revolution supplemented and replaced the muscles of humans and animals by mechanical methods. The computer extends this development to supplement and replace some aspects of the mind of human beings by electronic methods. And it′s the capacity of the computer for solving problems and making decisions that represents its greatest potential and that poses the greatest difficulties in predicting the impact on society.
why does the author mention the explosion of the Challenger space shuttle and the Russian nuclear accident at Chernobyl?

A.To show the worry that technology may eventually destroy our world.
B.To tell the readers that as a human creation, technology may go wrong and do harm to human.
C.To emphasize the responsibility we have in ensuring human safety in a technological world.
D.To stress the fact that technology usually goes wrong if not given close examination.
