问题     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 of robot serves the purpose equally well. The explosion of the Challenger space shuttle (挑战者号航天飞机) 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 (变得混乱) 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 a 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 con fined 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. It is 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.
According to the author, the introduction of the computer is a revolution mainly because______.
选项 A、the computer has revolutionized the workings of the human mind
B、the computer can do the tasks that could only be done by people before
C、it has helped to switch to an information technology
D、it has a great potential impact on society
答案D
解析 事实辨认题。问在作者看来，计算机的问世是一场革命的原因是什么。文章第三段说：“将它(指工业革命)看作一场革命的首要原因是它带来了社会的巨大变化。’第四段又说：“与此类似，计算机也将引起美国社会生活结构的一场革命。”“计算机解决问题和做出决策的能力表明了它的巨大潜力，并使得预测其对社会的巨大影响很难。”综合起来看，则不难选定D项正确。
