英语范文

The last century featured many technological revolutions the world over. Among them, computer technology has been the most remarkable. Its rapid development and proliferation of use have changed everything from the way the work is done to cutting-edge scientific research.

First of all, computers free us from heavy workload. With the advent of word processors, mistakes in articles can be corrected and editing done without the need to rewrite or retype the entire paper. It is also possible to generate large, stylized type for headings and ill ustrationsso that books can be prepared ready for print.

The computer has also brought about great changes in the financial and scientific world. A good case in point is the use of computers in banking. With its help, financial institutions are able to keep track of balances and transactions automatically and more efficiently than they did in the past. In the scientific community, one of its advantages is its“number-crunching” power. This has made accurate weather forecasting possible. It spower has also enabled scientists to get a clearer picture of the human genome.

However, not all the changes have had a positive impact on human beings and as a whole. There are quite serious health consequences of a sedentary life in front of a computer, the most obvious being eye strain. Furthermore, it is the social consequences that are more alarming. The computer and the Internet have made direct human contact less and less necessary, which had led to human relationships becoming less close and more confusing.

Although some undesirable consequences have arisen from using computer, on the whole, I feel we should embrace the technological advance. There is every reason to believe that computers represent even more efficiency and effectiveness in the future.

题目：

　　二十世纪拥有许多科技发明，选择其一，描述该发明带给人们的变化并且讨论这些变化是否都具有进步意义。

译文：

　　上个世纪，在世界范围内发生过很多次重要的科技革命。其中最引人瞩目的就是计算机技术带来的变化。计算机科技的快速发展和广泛应用使整个社会产生了巨大的变化，这种变化是从工作方式延伸到边缘科学的研究。

　　首先，计算机把我们从繁重的工作中解脱出来。随着文字处理器的使用，人们不需要重写或是重新打印，就可以改正文章中的错误并且编辑整张报纸。计算机还能够为即将印制的书籍制作大的格式化的标题和插图。

　　在金融和科技领域里，计算机也带来了巨大的变化。计算机在银行中的使用就是一个很好的例证。在计算机的帮助下，金融机构比过去能够更加自动有效地了解余额和交易。在科学领域里，计算机的优势“数字捣弄”功能，能够使人们准确地预报天气。这个功能还能够帮助科学家绘制更清晰的人类基因组。

　　然而，并不是所有的变化都对人类产生积极的影响。在计算机前坐得过久会严重影响人们的身体健康， 最明显的就是眼部疲劳。此外，它的社会影响也很令人担忧。计算机和互联网减少了人们的直接交往，使人与人之间的关系越来越疏远，越来越混乱。

　　尽管使用计算机带来一些令人不愉快的后果，但总的来说，我认为我们应该欢迎科技的进步。

　　有充分的理由相信，计算机在未来会带来更高的效率。
