at present,piracy is becoming unprecedentedly visible in china,any product,like tape,cd and hi-tech device can be copied,not to mention book.shortly after a newly-published book hits the shelves,people will unsurprisingly find its pirated counterparts in the stores.it has been widely believed that piracy has caused a great loss to legitimate producers,inventors and authors in many ways.to start with,pirated products often cost much less than the original ones,so they enjoy unbeatable advantage in price in spite of their relatively poor quality.the original ones,on the contrary,sell poorly.as far as pirated books are concerned,they do great harm to the authors/ reputation due to their misprints.in the long run,pirated products may also have negative impacts on customers since those legitimate producers' enthuslasm may be greatly hurt by the fact that some customers are more indined to purchase pirated products.

　　in my opinion,it's high time that the govement called on everyone to start the battle against piracy.besides,as customers,we should develop our consciousness to resist pirated products.and law should be strictly carried out to ban piracy from spreading any further.only in this way can we put an end to piracy and create a healthy environment for both customers and producers
