If you fit the statistical averages, you spend about two hours a day surfing on Internet. It seems that Internet enriches our daily life. But like everything else, Internet is a mixed blessing.　　Generally, the merits of Internet can be listed as follows. First, with Internet, we can be well informed of what has happened home and abroad and thus our horizons are broadened. What's more, Internet serves people and corporations well. There is a trend that more and more people go shopping online instead of going to shops. Also, many large corporations are doing business through Internet and this saves them much time and effort needed when they do business in traditional ways. Most important of all, Internet has shortened the distance between people. It is not a dream that the world is becoming a global village.

Firstly, we cannot turn a blind eye to the viruses that often make a bad impact on our computers' systems. Besides, we cannot turn a deaf ear to the fact that many hackers intrude upon our financial and personal information on Internet.　　Now the conclusion is self-evident. The benefits of Internet outweigh its dangers. Actually, whether helpful or harmful, the trend that Internet will exert an important influence on our ways of thinking and life styles cannot be stopped. We need to make full use of the merits of Internet and minimize their demerits.
