有人認為預測電腦的功能將超過人腦。請就人腦與電腦的區別寫一 篇作文，你可以從體積、運算速度和結構等方面進行對比。
【經典範文】：The Brain and the Computer
Some recent developments in computer industry make scientists predict that the gap between human beings and the machine will be closed by the year 20000.
To understand the significance of this prediction, let us compare the human brain with existing computers. The brain consumes electrical energy at the rate of 25 watts and occupies volume of one tenth of a cubic foot. The brain houses between 10 billion and 100 billion items of information. Every brain cell is directly connected to many other cells. As a result, the cells in which information is stored can communicate with thousands of other cells.

【譯文賞析】：人腦和電腦
根據最近計算機行業的`一些進展，科學家們做出預測：電腦將於 20000年時接近人腦。
為了弄清這項預測的重要性，讓我們來對比一下人腦和目前的電腦。 人腦消耗電能的速度為25瓦，大小為一立方尺的十分之一。人腦能儲 存上百億到上千億條資訊。每個腦細胞都直接與許多其他細胞相連。因 此，儲存著資訊的那些細胞便能與幾千個其他細胞發生聯絡。相比之下， 電腦耗能一百萬瓦，佔地幾百立方尺。電腦的記憶正如鴿舍中的一個小 格子，沒有思考能力，也無法與外界取得聯絡。
總之，電腦根本不能與人腦相提並論。
【詞彙表達亮點】
