The United States is not the only country affected by the“computer revolution”,All the major countries of the world have computers ,and the developing countries have also realized that computers play a big part in their economic development.
Usually what one sees is a machine that looks like a typewriter ;it is called a computer terminal（终端）But computers are also used in unseen ways For example they determine how much tine there should be between traffic signals to prevent traffic problems and to keep millions of cars moving in an orderly flow When you buy a car ,a factory process （过程）that is controlled by a computer enables you to obtain a car with your own choice of colours and special features （特征）in just a few weeks’ time In medical laboratories ,com-puters have reduced the mistakes in testing ,and they have saved doctors’ countless hours of work Before long ,medical histories of all Americans will be kept in computer “banks”.If a person becomes ill far from his home ,local doctors will be able to get his medical record immediately ,In science the computer has performed in minutes experiments which would have required thousands of hours of work by human hands and minds.
Most experts agree that computers are necessary to solve the problems of increasing population ,city living ,and public affairs Without computers, the jobs of solving these problems would require millions of workers to do tons of paperwork Before any computer can work on any problem, it must be told what to do Someone must program the computer ,step―by―step. At first this was done by having the programmer write out his instructions in the form of numbers which would be“understood”by the machine ,Within a short time, attempts were made to perform a system that would enable humans to communicate programmer could use words that had meanings for him ,and another program in the ma-chine would translate the words into the computer’s number system.
Without special training ,in is impossible to under stand exactly how a computer does int work however ,many people without scientific training use computers in their daily lives .In some American schools for example young children are being taught by comput-ers for part of the school day.
The use of computers in school has worried some Americans There are those who fear is will remove human element（成分）from teacher-student relationships .On the other hand there are educators who consider computer program a valuable means of freeing teachers from the more boring and tiring tasks ,thus enabling them to spend more time with a single student.
In education ,as in business and industry science and medicine ,computers play an important part in almost every type of operation the future will bring major advances in computer technology ,which will aid man in his efforts to improve the world.

The United States is not the only country affected by the“computer revolution”,All the major countries of the world have

computers ,and the developing countries have also realized that computers play a big part in their economic development.
并不是只有美国受到“计算机革命”的影响，世界上其他的主要国家也拥有数以万计的电脑，发展中国家也意识到电脑在国家经济发展中扮演

着很重要的角色。
Usually what one sees is a machine that looks like a typewriter ;it is called a computer terminal（终端）But computers are

also used in unseen ways
通常人们见到的电脑是长得有点像打字机一样的机器；它被称为电脑终端，但是电脑也用在看不见的领域中。
For example they determine how much tine there should be between traffic signals to prevent traffic

problems and to keep millions of cars moving in an orderly flow
举例来说，电脑可以测出交通信号灯的间隔时间是多少，从而来避免交通拥堵的问题，并让数以万计的车辆行驶顺畅。
When you buy a car ,a factory process （过程）that is controlled by a computer enables you to obtain a car with your own choice of colours and special features （特征）in just a few weeks’ time
当你买车的时候，只需要几周的时间，工厂通过电脑的操作来制造出符合你要求的颜色以及特殊要求的轿车出来。
In medical laboratories ,com-puters have reduced the mistakes in testing ,and they have saved doctors’

countless hours of work Before long ,medical histories of all Americans will be kept in computer “banks”.
在药品实验室里，电脑可以减少在实验过程中的失误，并且为医生省下了很多时间。在不久以后，所有美国人的病历将被保存在电脑的“银行里”
If a person becomes ill far from his home ,local doctors will be able to get his medical record immediately ,
如果一个人在远离家里的地方突然患病，那么当地的医生就可以立即获得他的病历资料。
In science the computer has performed in minutes experiments which would have required thousands of hours of work by human hands and minds. Most experts agree that computers are necessary to solve the problems of increasing population ,city living ,and public affairs
在科学领域，计算机可以在几分钟的时间内计算出人类需要上千小时才能算出的实验结果。
大多数专家认同，在解决人口剧增，城市生活条件以及公共事务等问题上是离不开电脑的帮助的。
Without computers, the jobs of solving these problems would require millions of workers to do tons of paperwork Before any computer can work on any problem, it must be told what to do Someone must program the computer ,step―by―step.
没有电脑的话，要解决这些问题就要花上成千上万的工人完成成吨计算的纸面工作。在电脑解决任何问题之前，都必须要一步一步的输入相应的程序。
At first this was done by having the programmer write out his instructions in the form of numbers which would be“understood”by the machine , Within a short time, attempts were made to perform a system that would enable humans to communicate programmer could use words that had meanings for him ,and another program in the ma-chine would translate the words into the computer’s number system.
在初及阶段，这一工作是由程序员利用数字来写出他的指示让电脑进行“理解”的。不久以后，一种能让人类与电脑进行交流的带有特定含义的单词的系统孕育而生，而在电脑中的另一个程序可以把这些单词翻译成数字形式输入到电脑的数字系统中。
Without special training ,in is impossible to under stand exactly how a computer does int work however ,many people without scientific training use computers in their daily lives .In some American schools for example young children are being taught by comput-ers for part of the school day.
如果不通过特殊的学习，是无法理解电脑是如何运行的。然而，有许多没用经过正规学习的人们能在日常生活中使用电脑。比如在美国的某些学校里，电脑被作为一门课程让学生们学习。
The use of computers in school has worried some Americans There are those who fear is will remove human element（成分）from teacher-student relationships .On the other hand there are educators who consider computer program a valuable means of freeing teachers from the more boring and tiring tasks ,thus enabling them to spend more time with a single student.
在学校里使用电脑，这使得某些美国人担心这样会造成师生关系的疏远。另一些教育家们认为电脑称训的一个有价值的意义在于将老师从更加枯燥和疲劳的教书任务中解脱出来，这样能让他们有更多的精力花在单一的学生身上。
In education ,as in business and industry science and medicine ,computers play an important part in almost every type of operation the future will bring major advances in computer technology ,which will aid man in his efforts to improve the world.
不仅在教育界，在金融界、工业技术和医药业也一样，电脑在所有的社会分工中都扮演着重要的角色，未来的计算机技术领域将带来重大进展，这将帮助人类来更好的改善世界。
