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.

Text 3 Scientists have found that although we are prone to snap overreactions,if we take a moment and think about how we are likely to react,we can reduce or even eliminate the negative effects of our quick,hardwired responses.Snap decisions can be important defense mechanisms;if we are judging whether someone is dangerous,our brains and bodies are hardwired to react very quickly,within milliseconds.But we need more time to assess other factors.To accurately tell whether someone is sociable,studies show,we need at least a minute,preferably five.It takes a while to judge complex aspects of personality,like neuroticism or openmindedness.But snap decisions in reaction to rapid stimuli aren't exclusive to the interpersonal realm.Psychologists at the University of Toronto found that viewing a fastfood logo for just a few milliseconds primes us to read 20 percent faster,even though reading has little to do with eating.We unconsciously associate fast food with speed and impatience and carry those impulses into whatever else we're doing.Subjects exposed to fastfood flashes also tend to think a musical piece lasts too long.Yet we can reverse such influences.If we know we will overreact to consumer products or housing options when we see a happy face（one reason good sales representatives and real estate agents are always smiling）,we can take a moment before buying.If we know female job screeners are more likely to reject attractive female applicants,we can help screeners understand their biases—or hire outside screeners.John Gottman,the marriage expert,explains that we quickly“thin slice”information reliably only after we ground such snap reactions in“thick sliced”longterm study.When Dr.Gottman really wants to assess whether a couple will stay together,he invites them to his island retreat for a much longer evaluation;two days,not two seconds.Our ability to mute our hardwired reactions by pausing is what differentiates us from animals:doges can think about the future only intermittently or for a few minutes.But historically we have spent about 12 percent of our days contemplating the longer term.Although technology might change the way we react,it hasn't changed our nature.We still have the imaginative capacity to rise above temptation and reverse the highspeed trend.
The time needed in making decisions may_____

A.vary according to the urgency of the situation
B.prove the complexity of our brain reaction
C.depend on the importance of the assessment
D.predetermine the accuracy of our judgment

People are indulging in an illusion whenever they find themselves explaining at a cocktail（鸡尾酒）party，say，that the are“in computers，”or“in telecommunications，”or“in electronic funds transfer”.The implication is that they are part of the high-tech world.Just between us，they usually aren’t.The researchers who made fundamental breakthroughs in those areas are in a high-tech business.The rest of us are（ ）of their work.We use computers and other new technology components to develop our products or to organize our affairs.Because we go about this work in teams and projects and other tightly knit working group（紧密联系在一起的工作小组），we are mostly in the human communication business.Our successes stem from good human interactions by all participants in the effort，and our failures stem from poor human interactions.

A.creators
B.innovators
C.appliers
D.inventors

A.afraid of technology
B.skilled in technology
C.ignorant of technology
D.incompetent in technology
