In the modern times,the world is becoming smaller and smaller with many new technical tools,and the Internet,I think,is one of the most important tools!

         But,nowadays,some people think the Internet has brought us more harms than other things,so we shouldn't advocate it;some people think the Internet has brought us more useful things than others,so we shoud use even depend on it.
         Every coin has two sides.In my opinion,the Internet has brought us something useful as it also has brought us something harmful.We should treat it correctly and scientificly.The Internet is closely related to our life now,and we should make good use of it,in the meantime,we should also defense something harmful from us,like the Internet crimes and so on.In this way will we build a harmony and benificial Internet environment and atmosphere.
