I was built as an Analytical machine by Charles Babbage.skimmingMy real father, Alan Turing, … I was always lonely standing there by myself, until in early 1960s they gave me a family connected by a network.These changes only became possible as my memory improved. Since the 1970s many new applications have been found for me. Over time I have been changed quite a lot.Para 1:Para 2:Para 3:Match the main ideas and the paragraphs.D.Choose the main idea of this passage. The computer wants to find “who he is”. The fun_ction(功能) of the computer. The computer becomes popular around the world. The history and the applications of the computer.Where were you in 1642? In France. What happened to you after nearly two hundred years? I was built as an Analytical Machine by Babbage.Fast readingWhat were you called in 1936? A universal machine. What happened to you in the 1970s? I have been used in offices and homes.我是谁？ 经过一段时间我已经被改变了很多。1642年我在法国 诞生时是一台计算机器。尽管当时我还年轻，但是我能 简化一些复杂的数学题。我发育缓慢，差不多到了两百 年之后，查尔斯.巴比奇才把我制成了一台分析机。在 操作员用穿卡孔为我设计程序后，我能够进行逻辑“思 考”，并且能够比任何人更快地算出答案。那时这被当 作是一次技术革命，也是我“人工智能”的开始。在 1936年，我真正的父亲艾伦.图灵写了一本书，讲述了 怎样使我成为一台“通用机器”来解决任何数学难题。 从那时起，我在体积和脑容量方面迅速成长。到二十世 纪四十年代，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，这个现实也使得我的设计者 担心。随着时间的推移，我被弄得越来越小。自二十世 纪七十年代以来，我一直被用在办公室和家庭里，先是 用作个人电脑，后来又做成便携式。这些变化只是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中，以后是晶体管上，后来是非 常小的芯片上。因此，我已经完全改变了我的形状。随 着我年龄越来越大，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 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，直到二十世纪六十年代初，人们才给了我一 个用网络联成的家庭。我能够通过万维网和其他人分享 我的知识。 从二十世纪七十年代起，我又被开发了很多新的用途。 我在通讯、金融和商业领域变得非常重要。我还被放在 机器人里面，被用来制作移动手机，并且用来帮助作医 疗手术。我还被放置在航空火箭里去探测月球和火星。 不管怎样，我的目标是给人类提供高质量的生活。现在 我充满了幸福感，因为我是人类忠实的朋友并时时给他 们提供帮助。nComprehendingthe second generationthe third generation (1964-1971)the fourth generation (1971- )The first generation(1956-1963) T(19h45e-1956h) istory of computersWhat is PC?
