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世纪最重要的改变

　　20世纪有很多重要的变革。从政治结构到人类平均寿命的长短，这些变革的影响层面很广泛。因此，我们与上上代的生活有极大的差异。很难说有那些重大的变革是应该被牢记的，但就我而言，电脑的发明是个不错的选择，因为它在很多方面都影响了我们的生活。

　　电脑影响的其中一个层面就是对通讯的冲击。由于互联网与电脑控制卫星的出现，现在远距离的通讯已经非常快速而且划算。这使得世界变得更小，而且对商业有很大的影响，也让全球的生产力增加了。电脑的另一个影响是，它改变了我们的日常生活方式。电脑让信息寻找及管理成为简单的事情，这带给我们非常多的便利。我们大部分的人每天或多或少都会使用电脑。最后，电脑科技的发展造就了许多其他科学上的进步。电脑被用来救活医院里的病人、寻找海底的新能源以及探索外太空。电脑的好处似乎是多到数不清。

　　总之，电脑对欧文们生活的许多层面都造成了很大的影响，因此我认为这项发明是20世纪最值得纪念的变革。没有其他产品或事件曾影响这么多人。它的影响力在世界各地都可以感受得到，而且在未来还会持续不断地增强。
