1. the brain and puter
Some recent developments puter industry make scientists predict that the gap between beings and the machine will be closed by the year 2000.
To understand the significance of this prediction,let pare the human brain with puters .The brain consumes electrical energy at the rate of 25 watts and occupies volume of one tenth of a cubic foot. The brain houses between 10 billion and 100 billion items of information. Every brain cell is directly connected to many other cells. As a result,the cells in which information is stored municate with thousands of other cells。In contrast ,puter consume 1000,000 watts of electrical power and occupies hundreds of cubic feet of space。puter memory is like a cell of pigeonholes,with no thinking capacity and no connections elsewhere。
In a word,the electronic brains can hopelessly eed parison with human brains。

人脑和电脑
根据最近计算机行业的一些进展,科学家们作出预测:电脑将于20000年时接近人脑。
为了弄清楚这项预测的重要性,让我们来对比一下人脑和目前的电脑。人脑消耗电能的速度为25瓦,大小为一立方尺的十分之一。人脑能储存上百亿到千亿条信息。每个脑细胞都直接与许多其他的细胞相连。因此,储存着信息的那些细胞便能与几千个其他细胞发生联系。相比之下,电脑耗能一百万瓦,占地几百立方尺。电脑的记忆正如鸽舍中的一个小格子,没有思考能力,也无法与外界取得联系。
总之,电脑根本不能与人脑相提并论。
