人教版高中英语必修二第三单元课文翻译
人教版高中英语必修二第三单元课文翻译第三单元电脑阅读一我是谁随着时间的推移我被改变了很多。
在1642年的法国，我是作为一个计算机器而开始的。
虽然我很年轻我可以简化一些计算题。
在我被CharlesBabbage改造成分析机器之前我很慢的发展了接近两百年。
之后我被一个操作员用带洞的卡调制成了可以合逻辑地思考并且比任何人都快地得出一些问题的答案。
那是一个被成为技术改革的时候并且开始了我的人造智能。
在1936年我真正的父亲Alan Turing写了一本关于我如何像普遍的机器一样去解决任何困难的数学问题的书。
从那起，我在体积和智能方面快速的发展。
在1940年我变得像一个房间一样大，并且我想知道我是否还能变得更大。
然而，事实也在困扰着我的设计者。
随着时间的推移，我被制的更小。
首先是个人电脑再到后来的手提电脑，在1970年我已经开始被用在办公室和家里。
这些变化只因为我记忆力的增强。
开始记忆被存放于电子管里，然后是晶体管和后来更小的晶片。
因此我改变了我的整个外型。
随着我慢慢变老我也慢慢的变小。
随着时间推移我的记忆力发展的那么快，像头大象，我不会忘记任何我曾被告知的东西！而且我的记忆力变得如此的大以至于我都不敢相信!不过我总是自己那么孤单的站在那里，直到1960年他们通过网络给了我一个家庭关系。
我能够通过万维网和其他的电脑分享我的知识。
从1970年起很多新的应用为我而被发明。
我在交流，金融和贸易方面变得重要。
我同样被放进遥控装置中被用来制造移动电话也帮助医学手术。
我已经被放进太空火箭并被送去探测月亮和火星。
即使如此，我的目的是为人们提供高质量的生活。
我现在充满快乐应为我成为了人类种族中的一个忠心的朋友和帮助者。
阅读二机器人-Andy我是一个机器人球队的一份子。
我们被允许在一齐踢足球大约一年了。
我像一个人类一样高大。
事实上，我长得也像人类。
在球队里我是前锋因此我要跑得非常快。
我的电脑芯片帮助我移动并且像人类一样思考。

while looking at them.And they are required to use the given expressions in their discussion to express their ideas.T：B oys and girls，today I am going to introduce some machines to you.Now let’s see whether you can name them in English correctly，and talk about them.Now work together with your partners and try to find out what they have in common.Two minutes late，five students are asked to talk about them in class.S1：An abacus is an old calculating machine used in China until now.S2：A huge computer is built to solve some mathematical pro blems.But，in my opinion，it is too big.S3：A calculator is a new calculating machine which can solve a large number mathematical problems.And I think it is very convenient to carry and use，so we ofte n use it.S4：A PC is a personal computer，which can solve all kinds of problems and is widely used in offices，schools，shops，at homes，etc.now.S5：A notebook computer is a kind of useful computer which can be taken conveniently like a notebook.But I think it is too expensive.T：Quite good.It seems that you are all quite familiar with these machines.But can you tell what they have in common?Any volunteers?S6：Let me try.I think they all calculate something.They can deal with some mathsproblems.S7：I believe that they are our good friends.With their help we can finish our work quickly.S8：The 21th century is the century of information technology.As middle

work.You are using the computer to teach us English，aren’t you?S11：In my opinion，in the modern society，using the computers means grasping a tool of controlling the world.We may communicate with each

have.I was in France as a calculating machine in 1642.In 1822，I was built as an Analytical Machine by Charles Babbage.I was called “a universal machine”in 1936，as I could solve any mathematical problem.In the 1960s，I was given a family connected by a network，so that I could share information with others and we could talk to each other.In the 1970s，I was brought into people’s homes.T：You are so quick-minded that in such a short time you could find out all the answers to the questions.Your mind really works like a computer!Step 4 ComprehendingTask 3.Fill in the timeline to remember the

“universal machine”to solve any mathematical ter，people discoveredthe computer had “artificial intelligence”.In the 1960s，the computer got his new transistors.Its size was totally changes at that time.And in the early 1960s，the first family of computers were connected to each other.In 1970s，computers have brought into people’s homes.Now computers have been used by billions of people to deal with information and communicate with each other around the world by the Internet.T：Congratulations!You’ve done very well.Now try to do the same to your partners，OK!Step 2 Words and ExpressionsTask
