13、 my birth. 一、請將課文“Who Am I？”翻譯成漢語，然后對照助讀譯文自主勘誤 助讀譯文： 我是誰？ 經(jīng)過一段時間我已經(jīng)被改變了很多。1642年我在法國誕生時是一臺計算機器。盡管當時我還年輕，但是我能簡化一些復雜的數(shù)學題。我發(fā)育緩慢，差不多到了兩百年之后，查爾斯巴比奇才把我制成了一臺分析機。在操作員用穿卡孔為我設(shè)計程序后，我能夠進行邏輯“思考”，并且能夠比任何人更快地算出答案。那時這被當作是一次技術(shù)革命，也是我“人工智能”的開始。在1936年，我真正的父親艾倫圖靈寫了一本書，講述了怎樣使我成為一臺“通用機器”來解決任何數(shù)學難題。從那時起，我在體積和

14、腦容量方面迅速成長。到20世紀40年代，我已經(jīng)長得像一間屋子那么大，我不知道是否還會長得更大。但是，這個現(xiàn)實也使得我的設(shè)計者很擔心。隨著時間的推移，我被弄得越來越小。自20世紀70年代以來，我一直被用在辦公室和家庭里，先是用作個人電腦，后來又做成便攜式。 這些變化只有隨著我的存儲能力的不斷提高才能成為可能。最初是被存儲到電子管中，之后是晶體管上，后來是非常小的芯片上。因此，我已經(jīng)完全改變了我的形狀。隨著我年齡越來越大，我也變得越來越小。隨著時間的推移，我的記憶能力發(fā)展得如此之快，就像一頭大象一樣，從來不會忘記告訴我的任何事情！我的存儲容量變得如此巨大，連我自己都不能相信！但是我總是孤孤單單地

15、站在那里，直到20世紀60年代初，人們才給了我一個用網(wǎng)絡(luò)聯(lián)成的家庭。我能夠通過萬維網(wǎng)和其他人分享我的知識。 從20世紀70年代起，我又被開發(fā)出了很多新的用途。我在通信、金融和商業(yè)領(lǐng)域變得非常重要。我還被放在機器人里面，被用來制作移動手機，并且用來幫助做醫(yī)療手術(shù)。我還被放置在航空火箭里去探測月球和火星。不管怎樣，我的目標是給人類提供高質(zhì)量的生活?，F(xiàn)在我充滿了幸福感，因為我是人類忠實的朋友并時時給他們提供幫助。 二、課文段落精選背誦(請注意名詞的使用) Who Am I Over time I have been changed quite a lot.I began as a calcu
