They say that we live in an era of internet. We send and receive e-mail on internet, search useful information from internet, play games on internet, get news from internet, read books on internet, make friends through internet and even make money through internet. It is apparently that internet has become one very important part of our life.

The improvement of internet technology has made the world a new and more advanced world. People correspond with each other through e-mail more conveniently and efficiently than before. Electronic business has made a zero distance between the buyers and suppliers. Google and Baidu searching engines supply more and more information by a very quick way. People who want to get information from the searching engines mentioned above can get what he want within only 1 second. Of course, the most important benefit of the internet to human life is to make the production far more efficient than before. So the improvement of internet technology has made a revolution in human life to some extent.

However, every thing has its two sides. The internet also brings us a lot of problems. Some people commit criminals through internet, for example, by stealing other people’s ID number to get illegal money. Children enjoy themselves too much in internet games to study. Employees travel on internet when they are working so that the work efficient is discounted. There are many other problems which are not mentioned here.

Generally, thinking and questioning are more important than excitement when we develop a new and good technology.
