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.

By using the phrase "the humanquality of technology", the author refers to the fact that technology________.查看材料
选项 A.has a great impact on human life
B.has some characteristics of human nature
C.can replace some aspects of the humanmind
D.does not exist in the natural world
答案D
解析语义题。A项在第三段中提到，是用来讲计算机的。B项“技术有人性的一些特征”，明显错误。C项“技术可以取代人类思维的某些方面”，原文没有提及。D项与第二段的“technology is a human creation；it does not exist naturally．"相对应，即技术不是自然的产物，而是人的创造，它需要不断完善的过程。而美国挑战者号航天飞机的爆炸以及俄罗斯切尔诺贝利核泄漏事件就是提醒我们人类技术的脆弱面：当计划好的系统突然出错时，却没有现成的解决办法。故选D。
