First of all,people are not always able to tell what is right or wrong from what is delivered by the media,especially children and teenagers.When they read and see something new,they tend to believe and accept it without filtering.For instance,many teenagers on the street smoke and fight,They learn it from films they watch and think it is the right fashion. Secondly,some people don't want to waste time on books and films of low quality. They are simply too busy to find the right and valuable things to read and watch. Experienced censors can be helpful as they can choose the good books and films and divide them into several categories with explanations of what they are about. Therefore,censorship on books,plays and films is not only necessary but also important. 说明：当总分出现0.5分时，在总分上增加1分取整。 212First of all，}}eoplc}}}re not always able to teal what is right or }s}rong front what is delivered by thE: media, especially child:rc}n and teenagers.
