Positive and Negative Aspects of the Internet
These years the Internet is widely popular in our life.However，as a coin has two sides，the Internet has both positive and negative aspects.
First of all，we can get a lot of useful information on the Internet，which enriches our knowledge.Furthermore，on the Internet we can make friends，send emails and shop etc.，which brings much convenience to us.However，the Internet has also brought about many problems.Many people spend most of their time on the Internet，playing games or chatting in the virtual world and so on.As a result，they neglect their study and work.Besides，they tend to give up much social communication.
As far as I am concerned，the Internet opens a window for me to know more about the outside world.In spite of its defects，I still believe that the Internet will bring us more benefits in the future if we use it in a proper way.
