题目内容
7．A．the future of computer-human relationshipB．the programming system of the computer
C．the reason of the complexity of the human brain
D．the possibility of a real supercomputer
E．the way for computers to kill humans
F．the shortages of the computer compared with a human brain
76．C
The difference between a human brain and a computer is more complicated than we can imagine．The large mammalian brain is the most complicated thing，for its size．Though the human brain only weighs three pounds，in that three pounds are ten billion neurons and a hundred billion cells．The many billions of cells are interconnected in such a vastly complicated network that we can't begin to explore as yet．
77．F
Even the most complicated computer man has yet built can't compare with the brain．Computer switches and processes number in the millions rather than in the billions．What's more，the computer switch is just an on-off device，whereas the brain cell is itself possessed of a complex structure．
78．B
It's frequently said that computers solve problems only because they are"programmed"to do so．They can only do what men have them do，in which way it is like the human brain．We can also do what we are"programmed"to do．Our genes"program"us the instant the zygote （授精卵） is formed，and our potentialities are limited by that"program．"
79．D
Surely，though，if a computer can be made complex enough，it can be as creative as people．If it could be made as complex as a human brain，it could be the replacement of a human brain and do whatever a human brain can do．Then the real supercomputer comes along．
80．A
In other words，once we pass a certain critical point，the computers will gain a dominating position and present a complexity explosion．In a very short time thereafter，computers may exist not only taking after the human brain，but far passing it．When the time comes，we might as well step aside and hand over all our work to them and really have them serve us．
分析 本文属于科普知识的范畴．讲解了人类大脑的复杂性以及与计算机之间的内在关系，并分析了人类与计算机未来发展的趋势．
解答 76----80 C F B D A
76．C．分析本段内容以及…in that three pounds are ten billion neurons and a hundred billion cells．可知，这一段主要分析了大脑复杂性的成因；故选C．
77．F．分析本段内容尤其是最后一句What's more，the computer switch is just an on-off device，whereas the brain cell is itself possessed of a complex structure．可知，这主要描述了与大脑相比，计算机的不足之处；故选F．
78．B．根据It's frequently said that computers solve problems only because they are"programmed"to do so可知，电脑之所以能做很多工作是因为被设定了特定的程序，所以B项中the programming system of the computer电脑的程序系统与此相吻合；故选B．
79．D．通过本段内容的描述尤其是最后一句Then the real supercomputer comes along．可知，这里主要介绍了未来超级电脑诞生的可能性；故选D．
80．A．通过最后的内容叙述we might as well step aside and hand over all our work to them and really have them serve us．可知，人类与计算机的关系未来有可能会给人类带来更大的好处；故选A．
点评 本文是说明文，题目要求从6个选项中选择恰当的语句填入空格处．这种类型的题目关键是符合逻辑和语境，要强调从上下文中寻找具体的解题依据．
