The Most Important Change of the 20th Century
There were a great many changes in the twentieth century. They affected everything from the political composition of the world to how long we can expect to live. As a result， our lives are very different from those of our great-grandparents. It is difficult to say which of these great changes should be remembered most but， in my opinion， the invention of the computer is a good candidate， for it has affected our lives in so many ways. One effect of the computer has been its impact on communication. Thanks to the Internet and computer-controlled satellites， it is now quick and cost-effective to communicate over great distances. This has made the world smaller and has had a great influence on business， leading to greater productivity worldwide. Another great effect of the computer is that it has changed the way we live our daily lives. It has made it a simple task to find and manage information and has brought us countless conveniences. Most of us deal with computers in one way or another every day. Finally， the development of computer technology has made possible a host of other scientific advances. Computers are used to save lives in hospitals， find new sources of energy under the sea and explore outer space. There seems to be no end to what computers can help us do. In short， the computer has had such a great impact on so many areas of our lives that I feel its invention was the most memorable change of the twentieth century. No other product or event has affected so many people. Its influence is felt around the world and will only continue to grow in the future.

20世紀(jì)最重要的改變
20世紀(jì)有很多重要的變革。從政治結(jié)構(gòu)到人類(lèi)平均壽命的長(zhǎng)短，這些變革的影響層面很廣泛。因此，我們與上上代的生活有極大的差異。很難說(shuō)有那些重大的變革是應(yīng)該被牢記的，但就我而言，電腦的發(fā)明是個(gè)不錯(cuò)的選擇，因?yàn)樗诤芏喾矫娑加绊懥宋覀兊纳睢?BR> 電腦影響的其中一個(gè)層面就是對(duì)通訊的沖擊。由于互聯(lián)網(wǎng)與電腦控制衛(wèi)星的出現(xiàn)，現(xiàn)在遠(yuǎn)距離的通訊已經(jīng)非常快速而且劃算。這使得世界變得更小，而且對(duì)商業(yè)有很大的影響，也讓全球的生產(chǎn)力增加了。電腦的另一個(gè)影響是，它改變了我們的日常生活方式。電腦讓信息尋找及管理成為簡(jiǎn)單的事情，這帶給我們非常多的便利。我們大部分的人每天或多或少都會(huì)使用電腦。最后，電腦科技的發(fā)展造就了許多其他科學(xué)上的進(jìn)步。電腦被用來(lái)救活醫(yī)院里的病人、尋找海底的新能源以及探索外太空。電腦的好處似乎是多到數(shù)不清。
