15、是孤孤單單地站在那里，直到20世紀(jì)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(jì)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(biāo)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
