考研英语作文：人脑和电脑的不同
要求写一篇关于电脑和人脑差别的文章：
The Difference between a Brain and a
Computer
he difference between a brain
and a computer can be expressed in a
single word: complexity.
Even the most complicated computer man
has yet built can't compare in
intricacy with the brain. Computer
switches and comportents number in
the
thousands rather than in the 's more, the computer
switch is just an on-off device,whereas
the brain cell is itself
possessed of a
tremendously complex inner structure.
Can a computer think? That depends on
what you mean by
solving a mathematical
problem is
can
mathematical
problems can be solved quite mechanically by
repeating
certain straightforward
processes over and over again. Even the
simple computers of today can be geared
for that.
Surely, though, if a
computer can be made complex enough, it can be
as creative as we are. If it could be
made as complex as a human
brain, it
could be the equivalent of a human brain and do
whatever a
human brain can do.
But how long will it take to build a
computer complex enough to
duplicate
the human brain? Perhaps not as long as some
think. Long
before we approach a
computer as complex as our brain, we will
perhaps build a computer that is at
least complex enough to design
another
computer more complex than itself. This more
complex computer
could design one still
more complex and so on and so on and so on.
In other words, once we pass a certain
critical point, the computers
take over
and there is a
thereafter, computers may
exist that not only duplicate the human
brain--but far surpass it.
原文翻译：要形容人脑与电脑的区别只需一个词，即：复杂。
即使是迄今为止
人类制造出的最复杂的电脑如果与人脑的复杂相比也望尘莫及。电
脑转换组合
出的数字只有千百万种而不是千百亿。更重要的是，电脑的转换器只是一个开
关装置，而大脑细胞本身就具有极其复杂的内部结构。
电脑会“思考”吗
?
这
就要看你所说的“思考”是指什么
了。如果解一道数学题是“思考”，那么电
脑会“思考”，而且比人脑快得多。当然，绝
大多数数学题都可以通过一遍一
遍机械地重复简单的程序而得到解决。即使是现今简单的
计算机也能做到这
点。
然而，电脑如果能造得够复杂， 它也能和我们一样富于创造力。如果它能
造得同人脑一样复杂，它便能与人脑相媲美，并
能做到人脑能做到的一切。
但
是，要造出一个与人脑一
样复杂的电脑要花多长时间呢
?
或许不会像有些人想象
的
那么长。在造出与人脑一样复杂的电脑之前，我们也许可能要先造出一个电
脑，它复杂得
至少能设计出比它本身更复杂的电脑。那个更复杂的电脑又能再
设计出比自己更复杂的电
脑，如此反复。
换言之，我们一旦突破了某个极点，
电
脑将盛行起来，并导致“复杂性爆炸”。不久，电脑将不仅复制人脑，而且
将远远超越人
脑。
