双刃剑英文

the internet is a double-edged sword As we all know,Internet is one of the most important and valuable inventions up to now in the world.Many students also like surfing the Internet. On one hand,some students uses the Internet to help with their studys,on the other hand,many students get lost in playing computer games which can do harm to their both health and studys. In my opinion,each coin has two sides,only if you take advantage of Internet,can you get masses of information usefull from the double-edged sword. 好累啊！
