英语翻译
The output is the last step in computer operation.It changes the computer’s results from binary machine language into a form that people can understand.There are several kinds of output devices.
Suppose a shoe store owner wants to know which style of shoe is selling best.He uses a printer.It actually prints,or types,the numbers of shoes sold on a long strip of paper.The machine printout shows him which shoes he should order.High-speed printers can print an entire ling at the same time turning out as many as twenty thousand lines a minute.
A city planner,though,may use her computer in a different way.She wants to plan a new bus route to serve the largest number of people.Using a plotter as the output,she gets a drawing,actually a map,showing the route chosen by the computer.
The telephone operator who looks up telephone numbers uses a computer.But she does not need a printed copy,nor a drawing of the number.Therefore,she has a computer terminal with a CTR .the screen flashes the number of a little while,and then it disappears,ready for the next request.
Students in many schools are taught by a computer.Some of these courses are in foreign languages.To learn a language,you must hear it spoken correctly.these computers have an audio output.They actually produce the sounds of the language perfectly pronounced.
The modern computer is truly an amazing machine.But it is not able to think ror itself.it is only as smart as the person who prepares its program.Nor can a computer produce correct answers unless it is fed correct data.
Many people are a little afraid of computers.They think of computers as machines with minds of their own.just remember this,though.A computer is nothing more than a human tool.It stretches our abilities.Just as you use a hammer to help you drive a nail into a wall,so you use a computer to help you solve a problem.Computers are our servants,not our masters.

people can understand.There are several kinds of output devices.
输出是计算机处理的最后一步.其结果用二进制转换成人们能够理解的形式.有许多种输出设备.比如一个鞋店老板想知道哪种鞋卖得最好,他使用打印机.可以打印鞋的数目在一长串纸上.输出结果可以让他选择他应该卖哪种鞋.在同一时间,高速打印机可以打印多至每分钟二万条线．但是一个城市规划师,可以用另一种方式使用电脑．她想规划出一条新的汽车路线以满足最大的人流量．使用一个计划作为输出,他可以得到图纸,实际是一张地图,通过电脑选择展现路线．查询电话号码的电话接线员也使用电脑．但她不需要打印和电话薄．因此,她有一个CTR电脑终端,瞬间可以显示出电话号码然后立即消失了准备下一次需求．在许多学校的学生也是用电脑授课．有些课还用外语．为了学习一门语言,你必须听得很准确．这些电脑有一个自动输出．他们实际上制造了语言正确标准的读音．现代电脑确实是一种令人惊奇的机器．但是它没有思想．只有当人给它准备了程序后才会变得聪明起来．一台电脑不会正确计算除非给它正确的数据．许多人有一点害怕电脑．他们认为电脑是一种有思想的机器．记住一点,电脑只是人类的一种工具而已．它们加强了我们的能力．电脑为你解决问题就像你用一个锤子把一颗螺丝钉敲进墙里一样．电脑是我们的仆人,而不是主人．
