15、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很担心。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。,这些变化只有随着我的存储能力的不断提高才能成为可能。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
16、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，我又被开发出了很多新的用途。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。,二、将下列单词或词组译成英语，然后参阅Unit 3的词
