　　Say No to Pirated Products

　　Nowadays, the problem of piracy has become more and more serious. Books,

　　tapes, VCDs and others high-tech products have been pirated. For instance, When a

　　new product comes onto market, most probably, its pirated counterpart will soon put

　　on its appearance in the market, too。

　　Piracy has caused a great loss to legitimate producers, inventors and writers in

　　many ways. To start with, the pirated products often cost much less than the genuine

　　ones so that they enjoy a better trading position in spite of their relatively poor quality.

　　The genuine products, on the contrary, sell poorly. What's worse, pirated books

　　sometimes do great harm to the authors' reputation due to some misprints. In the long

　　run, pirated products may have a negative impact on customers. Those legitimate

　　producers' creativity and enthusiasm may be deeply hurt by the fact that some

　　customers are more interested in the pirated products for the sake of small gains。

　　In my opinion, it's high time that everyone started the battle against piracy. First,

　　customers should develop their consciousness to resist the pirated products. Second,

　　the government should take effective measures to put an end to piracy. Finally, laws

　　must be strictly enforced to completely, ban piracy. Only in this way can we wipe the

　　pirated products out of our life。
