    A Society Without a Formal Authority

    In the seventeenth century,European soldiers who came across some Indian groups in the westem Great Lakes found that several native tribes(部落)were living in the area without a formal leadership system.They appeared to be"quite friendly with each other without a formal authority"!
    Not only did the Indians appear to lack a formal system of authority,but they also deeply hated any efforts to control their actions.All members of the tribes knew what was required of them by lifelong(一生的)familiarity with the tasks of the area. These tasks tended to be simple, since the Indians' rate of social change was slow. Thus,although subgroups such as soldiers had recognized leaders,no real authority was required.Rather than giving direct orders(which were considered rough),members of the tribes would arouse others to action by examples.
    It would be difficult,if not impossible,to carry out such a system in our own society.Most oi us have grown up under one authority or another for as long as we can remember. Our parents,our teachers,our bosses,our government all have the recognized right under certain conditions to tell u, what to do.The authority is so much a part of our culture that it is hard for us to imagine a workabl( society without it.We have been used to relying on authority to get things done and would probably be uncomfortable with the Indian methods of examples on a large scale.
    Of course,the major reason why the Indian system would not be suitable for us is that our society is too large.The number of tasks that various members of our society have to perform often undertight time and resource limitations could not be treated by the Indian system,in modern societies, the formal authority system is necessary to achieve any social objectives.

    According to the author,it is hard for a society to work without_______.
    A:a recognized authority
    B:enough money
    C:examples
    D:changes

    答案:A
    解析:
    本题问“下列哪项关于欧洲士兵的陈述是正确的?”文章第一段提到“欧洲士兵偶然遇见一群居住在西部大湖群的印第安人”。选项A、选项B、选项D在文中都未提到。因此选项C“他们偶然遇见一些印第安部落”符合题意。
    本题问“通过何种方法部落成员使其他成员做事”。文章第二段末尾提到“部落成员通过榜样的力量唤起其他成员采取行动,而不是发出直接命令”。由此可知选项 B“通过榜样”符合题意。
    本题是“根据作者的看法,一个社会没有······很难运转”。文章第三段中间提到:"The authority is so much a part of our culture that it is hard for us to imagine a workable society without it.”因此选A。
    本题是“读过文章,可得出结论······”。文章前两段谈到印第安部落的制度模式,第三段提到“It would be difficult, if not impossible, to carry out such a system in our own society",第四段解释我们的社会不能执行印第安人的制度的原因。综上所述,选项D“印第安制度很难在我们的社会中执行”符合题意。implement等于carry out(执行)。
    本题是“从文章中可以看出,执行我们社会中的任务······”。文章最后一段说“The number of tasks that various members of our society have to perform often under tight time"。因此选项C“没有任何施延”符合提议。

    Are You a Successful Leader?

    1 Almost nothing we do in this world is done in isolation.At work or at play,you'll find yourself in
    groups,working with other people:your team at work,a meeting with colleagues,your family,a holiday with
    friends,a group of students working together,a day out walking in the mountains,a group of neighbours want-
    ing to make changes.It is now recognized that being able to work successfully with other people is one of the
    major keys to success,partly because we need to do it so often.
    2 In almost every situation where you're in a group,you will need a skilled leader. All groups need
    leaders and all successful groups have good leaders.Groups without leaders or with weak leaders almost
    always break down. Members of a leaderless group often begin to feel dissatisfied and frustrated.Time is wasted
    and the tasks are not achieved.There are often arguments and tensions between people as there is nobody to
    keep the goals clear. Some personalities dominate and others disappear. Often group members begin not to
    come to meetings in order to avoid more disharmony.
    3 Some people are natural leaders.The celebrity chef,Antonio Carluccio says,"True leaders are born
    and you can spot them in kitchens."They're people who combine toughness,fairness and humour. Although
    a lot of people agree that there are some natural-born leaders,most people now recognize that leadership can
    also be taught.Our professional and experienced staff can train almost anyone how to be a successful leader.
    Good leaders don't make people do things in a bossy,controlling way.You can learn how to involve everyone,
    encouraging the whole group to work towards a common goal.
    4 Our training courses use activities and techniques to develop a range of qualities which are necessary
    to be a good leader. Seff-confidence is vital and being able to overcome your own fears about being a leader.
    Successful leaders also need to be calm and intelligent.They need to be able to work out good strategies and
    make sound judgements under pressure.Lastly,and probably most importantly,good leaders need to be sensi-
    tive,sociable and be able to get on with a wide range of people.Good leadership is essentially the ability to
    influence others and good leaders allow all members of the group to contribute.

    Groups often break down because of__________.
    A:the ability to work with others
    B:encouraging group members
    C:lack of good leaders
    D:bossing people around
    E:working out good strategies
    F: overcoming fears about being a leader

    答案:C
    解析:
    由第一段主题句“Almost nothing we do in this world is done in isolation”可知任何事情都不是我们单独完成的,即people are in groups。
    由第二段第一句“.You will need a skilled leader",在此skilled相当于good。
    由第三段倒数第二句中的“train almost anyone to be successful leader”可知培训可以造 就好的领导人才。
    第四段主要讲的是好的领导应有各种不同的才能。故选A。
    由第一段最后一句“…being able to work successfully with other people is one of the majorkeys to success...”可知选A。
    由第二段第三句“Groups without leaders or with weak leaders almost always break down", 可知选C。
    从第三段倒数第二句“don't make people do things in a bossy, controlling way",可知好的 领导不以发号施令和控制的方式让人做事,故选D。
    由第四段第二句“Self-confidence is vital and being able to overcome your own fears about being a leader",可知自信很重要,它可以帮你克服成为领导的恐惧。故选F。
