A Society Without a Formal Authority
In the seventeenth century, European soldiers who came across some Indian groups in the western 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 of 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 US what to d0.The authority is so much a part of our culture that it is hard for US to imagine a workable 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 under tight 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.

单项选择题 根据短文回答 31～35 题。 Sleep Necessary for Memories Burning the midnight oil before an exam or interview does harm to the performance according to a recent research which found that sleep is necessary for memories to be taken back into the brain.A good night's sleep within 30 hours of trying to remember.A new task is a required condition of having good recall in the weeks ahead,scientists have found.The research,published in the December issue of Nature Neuroscience,showed that it was the act of sleep,rather than the simple passage of time,that was critical for long-term memory formation.'We think that getting that first night's sleep starts the process of memory consolidation(巩固),'said Robert Stick gold,a sleep researcher at Harvard Medical School who conducted the latest study.'It seems that memories normally wash out of the brain unless some process nails them down.My suspicion is that sleep is one of those things that does the nailing down,'Professor Stick gold said.With about one in five people claiming that they are so chronically short of sleep that it affects their daily activities,the latest work emphasizes the less well-understood side effect-serious memory impairment(损害).Volunteers in an' experiment found it easier to remember a memory task if they were；allowed to sleep that night.But for those kept awake,no amount of subsequent sleep made up for the initial loss.Professor Stick gold's team trained 24 people to identify the direction of threediagonal(斜线形的)bars flashed for a sixtieth of a second on a computer screen full of horizontal(水平的)stripes. Half of the subjects were、kept awake that night,while the others slept.Both groups were allowed to sleep for the second and third nights to make up for any differences in tiredness between the volunteers.Those who slept the first night were significantly and consistently better at remembering the task while the second group showed no improvement despite enjoying two nights of catch-up sleep. 第 31 题 The research published in nature Neuroscience showed that what was essential to the formation of long-term memory was（ ）A．intelligence.B．time.C．food.D．sleep.
