考研英語作文：人腦和電腦的不同

1、考研英語作文：人腦和電腦的不同要求寫一篇關(guān)于電腦和人腦差異的文章：The Difference between a Brain and a Computerhe difference between a brain and a computer can be expressed in a single word: complexity.Even the most complicated computer man has yet built can't compare in intricacy with the brain. Computer switches and comporten

2、ts number in the thousands rather than in the billions.What's more, the computer switch is just an on-off device,whereas the brain cell is itself possessed of a tremendously complex inner structure.Can a computer think? That depends on what you mean by"think". If solving a mathematical

3、 problem is"thinking',then a computer can"think'and do so much faster than a man. Of course, most mathematical problems can be solved quite mechanically by repeating certain straightforward processes over and over again. Even the simple computers of today can be geared for that.Sur

4、ely, though, if a computer can be made complex enough, it can be as creative as we are. If it could be made as complex as a human brain, it could be the equivalent of a human brain and do whatever a human brain can do.But how long will it take to build a computer complex enough to duplicate the huma

5、n brain? Perhaps not as long as some think. Long before we approach a computer as complex as our brain, we will perhaps build a computer that is at least complex enough to design another computer more complex than itself. This more complex computer could design one still more complex and so on and s

6、o on and so on.In other words, once we pass a certain critical point, the computers take over and there is a"complexity explosion". In a very short time thereafter, computers may exist that not only duplicate the human brain-but far surpass it.原文翻譯：要形容人腦與電腦的區(qū)別只需一個詞，即：復(fù)雜。 即使是迄今為止 人類制造出的最復(fù)雜的

7、電腦如果與人腦的復(fù)雜相比也望塵莫及。電腦轉(zhuǎn)換組合 出的數(shù)字只有千百萬種而不是千百億。更重要的是，電腦的轉(zhuǎn)換器只是一個開 關(guān)裝置，而大腦細(xì)胞本身就具有極其復(fù)雜的內(nèi)部結(jié)構(gòu)。電腦會“思考嗎 ?這就要看你所說的“思考是指什么了。如果解一道數(shù)學(xué)題是“思考，那么電 腦會“思考，而且比人腦快得多。當(dāng)然，絕大多數(shù)數(shù)學(xué)題都可以通過一遍一 遍機械地重復(fù)簡單的程序而得到解決。即使是現(xiàn)今簡單的計算機也能做到這 點。 然而，電腦如果能造得夠復(fù)雜，它也能和我們一樣富于創(chuàng)造力。如果它能 造得同人腦一樣復(fù)雜，它便能與人腦相媲美，并能做到人腦能做到的一切。 但 是，要造出一個與人腦一樣復(fù)雜的電腦要花多長時間呢 ?或許不會像有些

8、人想象 的那么長。在造出與人腦一樣復(fù)雜的電腦之前，我們也許可能要先造出一個電 腦，它復(fù)雜得至少能設(shè)計出比它本身更復(fù)雜的電腦。那個更復(fù)雜的電腦又能再 設(shè)計出比自己更復(fù)雜的電腦，如此反復(fù)。 換言之，我們一旦突破了某個極點， 電腦將盛行起來，并導(dǎo)致“復(fù)雜性爆炸。不久，電腦將不僅復(fù)制人腦，而且 將遠遠超越人腦。Word是學(xué)生和職場人士最常用的一款辦公軟件之一，99.99% 的人知道它，但其實，這個軟件背后，還有一大批隱藏技能你不知道。掌握他們，你將開啟新世界的大門。Tab+Enter,在編過號以后，會自動編號段落Ctrl + D 調(diào)出字體欄，配合 Tab+Enter 全鍵盤操作吧Ctrl + L 左對齊，Ctrl + R 右對齊，Ctrl + E 居中Ctrl + F 查找，Ctrl + H 替換。然后關(guān)于替換，里面又大有學(xué)問！有時候Word文檔中有許多多余的空行需要刪除，這個時候我們可以完全可以用查找替換來輕松解決。翻開 編輯菜單中的 替換對話框，把光標(biāo)定位在查找內(nèi)容輸入框中，單擊 高級按鈕，選擇特殊字符中的 段落標(biāo)記兩次，在輸入
