Although I was young I could simplify difficult sums. I developed very slowly and it took nearly two hun

16、dred years before I was built as an analytical machine by Charles Babbage 【2】. After I was programmed by an operator who used cards with holes, I could “think” logically and produce an answer quicker than any person. At that time it was considered a technological revolution and the start of my “arti

17、ficial intelligence”. In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a “universal machine” to solve any difficult mathematical problem 【3】. From then on， I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room, and I wondered

18、 if I would grow any larger. However, this reality also worried my designers. As time went by 【4】， I was made smaller. First as a PC （personal computer） and then as a laptop, I have been used 【5】 in offices and homes since the 1970s.【1】over time（经过漫长的时间，随着时间的推移）在句中作状语，句子用现在完成时。have been changed是现在完成

20、 became possible as my memory improved. First it was stored in tubes， then on transistors and later on very small chips. As a result I totally changed my shape. As I have grown older I have also grown smaller. Over time my memory has developed so much that， like an elephant, I never forget anything

21、I have been told! 【6】And my memory became so large that even I couldnt believe it! But I was always so lonely standing there by myself, until in early 1960s they gave me a family connected by a network. 【7】 I was able to share my knowledge with others through the World Wide Web.Since the 1970s many

22、new applications have been found 【8】 for me. I have become very important in communication, finance and trade. I have also been put into robots and used to make mobile phones as well as 【9】 help with medical operations. I have even been put into space rockets and sent to explore the Moon and Mars. A

23、nyhow， my goal is to provide humans with a life of high quality 【10】. I am now truly filled with happiness that I am a devoted friend and helper of the human race！【8】have been found是现在完成时的被动语态。【9】as well as（也，又）连接并列结构make mobile phones和help with medical operations。【10】动词不定式短语to provide humans with.在

24、句中作表语。课文翻译我是谁？随着时间的推移我已经被改变了很多。1642年我在法国诞生时是一台计算（calculate）机器。尽管当时我很年轻，但是能简化（simplify）复杂的算术题（sum）。我发育非常缓慢，差不多过了两百年之后，查尔斯巴比奇才把我制成了一台分析机。在操作员（operator）用穿孔卡为我设计程序后，我能够进行逻辑（logically）“思考”，并且能够比任何人更快地算出答案。那时这被当做一次技术革命（technological revolution），也是我“人工智能”（artificial intelligence）的开始。在1936年，我真正的父亲艾伦图灵写了一本书，

25、讲述了怎样使我成为一台“通用（universal）机器”来解决（solve）任何数学（mathematical）难题。从那时起（from. on），我在体积和脑容量方面迅速成长。到20世纪40年代，我已经长得像一间屋子那么大，我不知道是否还会长得更大。但是，这个现实（reality）也使得我的设计者（designer）很担心。随着时间的推移，我被弄得更小了。自20世纪70年代以来，我一直被用在办公室和家庭里，先是用作个人（personal）电脑，后来又用作便携式电脑。这些变化只有随着我的存储能力的不断提高才成为可能。最初是被存储到电子管（tube）上，以后是晶体管（transistor）上，后

26、来是非常小的芯片（chip）上。因此（as a result），我完全（totally）改变了我的形状。随着我的年龄越来越大，我也变得越来越小。随着时间的推移，我的记忆能力发展得如此之快，就像一头大象一样，以致（so. that.）我从来不会忘记告诉我的任何事情！我的存储容量变得如此巨大，连我自己都不能相信！但是我总是孤孤单单地站在那里，直到20世纪60年代初，人们才给了我一个用网络（network）联成的家庭。我能够通过万维网（web）和其他人分享我的知识。从20世纪70年代起，我又被开发出了很多新的用途（application）。我在通信、金融（finance）和贸易领域变得非常重要。我还

27、被放在机器人里面，被用来制作移动（mobile）电话，并且用来帮助做医疗手术。我甚至还被放置在航空火箭（rocket）里去探测（explore）月球和火星（Mars）。不管怎样（anyhow），我的目标（goal）是给人类提供高质量的生活。现在我充满了幸福（happiness），因为我是人类（human race）忠实的朋友和帮手！.阅读理解AHe has a bright idea.Avery Hairston is lighting up peoples lives. The 15yearold from New York City created an organization called RelightNY. It helps people who have difficulty in paying their electricity bills by giving them special light bulbs （灯泡）, which cut longterm electricity costs. They are also better for the environment than common bulbs. “People who can afford the bulbs, which are a bit expe
