Compared to the living standard of the past period and nowadays, it is no denying that people’s nice living environment and high quality of living level owing to the rapid development of science and technology. The advantages are too obvious and valuable to be neglected. In the past time people have to spend days on the way if they want to visit friends who lived far away, now taking cars, trains or airplanes can greatly shorten the tour time. And the great invention i.e. the computer, makes people communicate more conveniently. However, there exist some disadvantages as well. For instance, the worst problem that is blamed for the quick development of science and technology is environmental pollution. A large number of cars and factory emerged in recent years, which is giving off lots of harmful gas and waste. In addition, the forest is reduced and many kinds of animals disappeared. It is time for us to take care of the earth.

与过去和现在的生活水平相比，不可否认的是，人们良好的生活环境和高质量的生活水平要归功于科学技术的快速发展。这些优势太明显和有价值，不容忽视。过去，如果人们想拜访住在很远的朋友，就不得不在路上呆几天，现在坐汽车、火车或飞机可以大大缩短旅游时间。伟大的发明，即计算机，让人们更方便地沟通。然而，也存在一些缺点。例如，科学技术快速发展的最大问题是环境污染问题。近年来出现了大量的汽车和工厂，排放了大量有害气体和废物。此外，森林正在减少，许多种类的动物消失了。真的是我们照顾地球的时候了。
