眾所周知，預(yù)測未來是非常困難的。舉個例子吧，在20世紀(jì)70年代中葉又有誰能想得到在20世紀(jì)末的時候，家庭用的計(jì)算機(jī)會像電視機(jī)一樣普遍？在70年代，計(jì)算機(jī)已經(jīng)相當(dāng)普及了，但只用在大公司，政府部門和大的組織之中，它們被稱為主機(jī)。計(jì)算機(jī)主機(jī)確實(shí)很大，常常占據(jù)了裝有空調(diào)的多間房間，雇用專職的技師，而且得用專門編寫的軟件才能運(yùn)行。雖然這種大計(jì)算機(jī)仍然存在，但它們的許多功能已被體積小但功能齊全的個人電腦——即我們常說的PC機(jī)——所代替了。

眾所周知，預(yù)測未來是非常困難的。舉個例子吧，在20世紀(jì)701975年，美國推出了一臺被稱為“牛郎星”的原始機(jī)型。嚴(yán)格地說起來，它可以被稱為第一臺“家用電腦”，而且它也指了今后的方向。70年代末，在牛郎星之后又出現(xiàn)了一種被稱為“蘋果”的機(jī)型。80年代初，計(jì)算機(jī)行業(yè)的王牌公司美國國際商用機(jī)器公司（IBM）生產(chǎn)出了世界上第一臺個人電腦。這種電腦采用了一種被稱為磁盤操作系統(tǒng)（DOS）的工作程序，而這種程序是由當(dāng)時規(guī)模不大的微軟公司生產(chǎn)的。IBM的個人電腦被大規(guī)模地模仿。從那些簡陋的初級階段，我們看到了現(xiàn)在都已普及的、使用簡便的家用電腦和多媒體的微機(jī)的發(fā)展。想一想這些發(fā)展的時間多么短，就更覺得英國人萊昂.巴格瑞特有著非凡的能力。他在60年代就能預(yù)言我們今天知道的計(jì)算機(jī)的一些用途。巴格瑞特根本不接受計(jì)算機(jī)可以學(xué)會自己去“思考”和計(jì)算可以“統(tǒng)治世界”這種想法，而這種想法是當(dāng)時的人們都愿意相信的。巴格瑞特預(yù)示有一天計(jì)算機(jī)可以小到拿在手上，計(jì)算機(jī)可以使辦公室人員和會計(jì)免除那些枯燥、重復(fù)的勞動。計(jì)算機(jī)的所有這些功能現(xiàn)在都變得很平常。當(dāng)然了，萊昂.巴格瑞特根本沒有可能預(yù)測到國際交互網(wǎng)——就是把計(jì)算機(jī)連結(jié)到電話線路上，以便和世界上任何一個地方的人立即進(jìn)行聯(lián)系的一個世界范圍的通訊系統(tǒng)——的發(fā)展。他也無法預(yù)測到我們可以利用國際交互網(wǎng)獲取有關(guān)任何已知專題的信息，以便在家里的屏幕上閱讀，如果愿意的話甚至可以將其打印出來。計(jì)算機(jī)已經(jīng)變得體積越來越小，功能越來越多，價格越來越低，這就是萊昂.巴格瑞特的預(yù)測非凡的地方。如果他或是像他的什么人今天還活著的話，他大概可以告訴我們下一個50年后會發(fā)生什么事情。1975年，美國推出了一臺被稱為“牛郎星”的原始機(jī)型。嚴(yán)格地Thanks!Thanks!新概念第三冊課件NCE3_lesson51第三冊課件第三冊課件Lesson51PredictingthefutureLesson511、notoriouslyadv.(尤指因壞事)總所周知地notoriousadj.be~for-Thisplaceis~forpoverty.befamousforbewell-knownfor1、notoriouslyadv.(尤指因壞事)總所周知地2、mainframen.主機(jī)mainboard主板monitor顯示器memory內(nèi)存
