In recent years, people are developing an inseparable relationship with Internet. As is known to all, it is convenient for us to click the mouse when surfing on line, either to entertain ourselves or to meet the works needs.

　　On the one hand, no one denies that Internet is currently one of the most useful media in our daily life. As a college student, I get on line every day to exchange information through e-mails with my net friends. But on the other hand, a good many people admit that they are too much addicted to Internet to maintain a regular and wholesome lifestyle.

　　Thus, it is necessary for us to use Internet in a reasonable way and restrain from overindulgence. After all，Internet is invented to enrich our life, and to improve the efficiency of our work rather than shackle us with a chain.
