I'm a middle school student name Li Ming．I'm writing to tell you something． Recently I have noticed many of my classmates often go to the cyber cafe near our school．I went there too in the other day．I was surprising to see many students playing computer games, watching films or chat．Some students are even talking about love affairs online．On my opinion, the cyber cafe should be a place which we can find much useful informations．The Internet should be a window to the outside world rather than place for games．The Internet is good if we make good use of them．Otherwise, it will do us great harm．So the local government should take measures to make sure that students use cyber cafes positively．
