问题 根据以下材料，回答题To live in the United States today is togain an appreciation for Dahrendorf′s assertion that social change existseverywhere. Technology, the application of knowledge for practical ends, is a majorsource of social change.Yet we would do well to remind ourselvesthat technology is a human creation; it does not exist naturally. A spear or arobot is as much a cultural as a physical object. Until humans use a spear to huntgame or a robot to produce machine parts, neither is much more than a solid massof matter. For a bird looking for an object on which to rest, a spear or robotserves the purpose equally well. The explosion of the Challenger space shuttleand the Russian nuclear accident at Chemobyl drive home the human quality oftechnology; they provide cases in which well-planned systems suddenly wenthaywire and there was no ready hand to set them right. Since technology is ahuman creation, we are responsible for what is done with it. Pessimists worrythat we will use our technology eventually to blow our world and ourselves topieces. But they have been saying this for decades, and so far we have managedto survive and even flourish. Whether we will continue to do so in the yearsahead remains uncertain. Clearly, the impact of technology on our livesdeserves a closer examination.Few technological developments have had agreater impact on our lives than the computer revolution. Scientists andengineers have designed specialized machines that can do the tasks that onceonly people could do. There are those who assert that the switch to aninformation-based economy is in the same camp as other great historicalmilestones, particularly the Industrial Revolution. Yet when we ask why theIndustrial 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 socialchange. It gave rise to mass production and, through mass production, to asociety in which wealth was not confined to the few.In somewhat similar fashion, computers promiseto revolutionize the structure of American life, particularly as they free thehuman mind and open new possibilities in knowledge and communication. TheIndustrial Revolution supplemented and replaced the muscles of humans and animalsby mechanical methods. The computer extends this development to supplement andreplace some aspects of the mind of human beings by electronic methods. Andit′s the capacity of the computer for solving problems and making decisionsthat represents its greatest potential and that poses the greatest difficultiesin predicting the impact on society.  The author considers the introduction ofthe computer as a revolution mainly because ________.查看材料A.it gives rise to mass productionB.it can do the tasks that could only bedone by people beforeC.it has helped to switch to an informationtechnologyD.it has a great potential impact onsociety
选项 A.it gives rise to mass production
B.it can do the tasks that could only bedone by people before
C.it has helped to switch to an informationtechnology
D.it has a great potential impact onsociety
答案 D
解析 细节题。根据第三段的第一句话“Few technological developmentshave had a greater impact on our lives than the computer revolution.",几乎没有什么技术发展能比计算机革命对我们的生活造成的影响更大了。再根据第三段中的“The primary reason why it was revolutionary is that it led to greatsocial change”可知．工业革命之所以是一场革命，主要原因是它引起了巨大的社会变革。计算机对人类社会生活产生了巨大的影响．所以计算机的引进也是一场革命。故选D。A项的主语是工业革命而不是计算机革命。B项的主语是specialized machines而不是computer。C项表述与原文不符。
