一、请将课文“WhoAmI?
”翻译成汉语,然后对照助读译文自主勘误
助读译文:
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,之后是晶体管上,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20世纪60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20世纪70年代起,我又被开发出了很多新的用途。
我在通信、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,并且用来帮助做医疗手术。
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。
