More and more teachers and parents have noticed another kind of pollution, _ _ _ _ came from the printed papers sold on streets.These printed things look like newspaper but have hardly anything to do with them. You can only find reading materials badly _ _ _ _ there----some are too strange for anyone to believe, _ _ _ _ are frightening stories of something even worse. However, many of the young students are getting absorbed in such poisonous reading, which costs them what they should pay for their breakfast and bring them nightmares and immoral ideas _ _ _ _ return. Homework is left undone, daily games lost.These sellers shout on streets selling their papers well. The writers, publishers and printers, _ _ _ _ they are, we never know, are making their silent money. The sheep skinned wolfˊs stories seem to have been forgotten once again.Why not forbid this kind of things at school? Yes, both teachers and parents have _ _ _ _ each other for more strict control of the young readers. Yet unfortunately, _ _ _ _ you want to forbid it, the more they want to have a look at it. Sometimes you may even find several children share one patched paper, which has traveled from one hand to _ _ _ _ driven by the curious nature.It really does harm to our society. It has already formed a sort of moral pollution. The _ _ _ _ teachers and parents need more powerful support. Meanwhile, the young readers need more interesting books to help them _ _ _ _ these ugly papers.
