  • 第2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 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.

    答案:B
    解析:
    推断题。根据第二段中的“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 fight."可知.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彻底暴露了技术的人性特征。也就是说技术是人为创造出来的,有时也会出错,会对人类造成危害。故选B。A项是悲观者的担忧,而作者不太认同;C项在这句话的后面提到了,且不是该例证的问题;D项中usually一词用的不恰当。

    Recently, the fact that more and more students are spending too much time playing computer games has aroused great concern. What influences do the computer games have on people and what should we do with them? Write a composition to give your views. You should write at least 120 words.

    正确答案:
    Nowadays, most of the boy students are crazy about playing computer games. The parents and teachers are very concerned with this situation. Then what influences does the computer game have on the players and what should we do with it?
    The computer games can give the players intellectual confidence and enhance their learning on a certain degree. However, their disadvantages are more prevailing. Most of the video games are of violent theme, which may desensitize the players to violence and alter their perception of reality. That may also give them the false idea that violence is an acceptable way to deal with problems and conflict. Meanwhile, spending too much time on video games would certainly affect their study. Concerning this, we should control children’s time spent on playing computer games and encourage them to do some other activities, such as doing sports, reading and travelling.

What bad influences do the computer games have on people and what should we do with them? Write a composition to give your views. You should write at least 160 words.

    正确答案:
    Recently, the fact that more and more students have spent too much time playing computer games has aroused great concern. It's high time to prevent them from indulging in those games.
    Though the computer and the Internet have brought us great convenience and pleasure in getting information, entertainment and contact with others, we should not ignore their negative impacts on people, especially young students. To begin with, to play computer games excessively can damage the players' physical health, especially their eyes. In addition, those students who are addicted to computer games tend to neglect their studies, idle away their time and even commit crimes.
    From what has been discussed above, I think it is imperative that some effective measures be taken to solve the problem. To begin with, the computer access for students should be controlled and the time students spend on computer games should be limited. Then, the quality of computer software and games for young students should be examined in case they are adversely influenced by inappropriate programs that involve violence and sex content. Finally, the law and the regulation should be made to protect students from being corrupted and misled by computer games. Meanwhile, parents and teachers should take responsibility for educating the students to realize the harmful effects of computer games.

    计算机这个术语描述由电子的和机电的部件组合而成的一种设备。计算机本身没有只能,因此称为硬件,仅仅是物理设备。硬件只有和其他要素连接才能使用,所有这些要素即为构成基于计算机信息系统的六要素:硬件、软件、数据/信息、人、操作程序和通信。
    系统定义为一组相关组件的集合,这些组件相互交互以完成一个任务,以实现一个目标。任何使用信息技术的组织会拥有一个基于计算机的信息系统,给管理人员(和各类员工)提供适当类型的信息以帮助他们做出决策。

    系统分析和设计是确定系统如何工作然后经过一系列步骤以使其更好。通常,采用系统方法来定义、描述和解决一个问题或满足一个目标。

    随着时间推移,新的市场机会、政府规定的变化、新技术的出现、公司兼并以及其他方面的发展等,使得组织需要改变其信息系统。当需要改变时,应用系统分析与设计的时机已经成熟。

    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.

    According to the passage, whenwill a spear or a robot has the quality of technology 查看材料

    A.When it is utilized by human beings.
    B.When it is used to produce new products.
    C.When it has some culture meanings asphysical object.
    D.When it is useful for both man andanimal.

    答案:A
    解析:
    细节题。根据第二段中的“Until humans use a spear to huntgame or a robot to produce machine parts, neither is much more than a solidmass of matter.
    ”可知.除非人们用矛去捕获猎物或用机器人去生产机器零件,否则二者都只不过是硬邦邦的物体而已。也就是说只有这些东西为人类所用的时候,它们才具有技术特性,故选A。
