  The Advantages and Disadvantages of the Internet

  The following aspects could best illustrate the advantages of the Internet.Net surfers (网上冲浪者) in different countries can share interesting knowledge and the latest information.Besides, the Internet has provided a major opportunity to buy and sell merchandise (商品).What is more, people may get medical help or even vote on the Internet.Its advantages seem countless.

  Behind all this glowing talk, however, are some problems.Internet makes people passive by stopping them making their own entertainment.So much that when there is a breakdown or jam, people may find that World Wide Web turns into World Wide Wait.What is worse, some children have access to the scenes of violence and sex.Apart from these, it can be affected by viruses(病毒) and hackers (黑客).

  We should handle its problems, meanwhile we should exploit its potential as well.With proper management of the Internet people ought to experience more fruits of the information revolution.All the wisdom of the ages, all the information that has enlightened mankind for centuries, should be available to us with the healthy development of the Internet.
