We have heard of counterfeiting before. Usually it refers to people making money by printing it instead of earning it. But counterfeiting also can involve all sorts of consumer goods and manufactured products. From well-known brand names such as Calvin Klein jeans to auto parts,counterfeiters have found ways to produce goods that look authentic. In some instances,counterfeit products look better than the original!

The demand of brand-name products has helped counterfeiting grow into a very profitable business throughout the world and into a serious problem for legal manufacturers and consumers alike. Faulty counterfeit parts have caused more than two dozen crashes. Most counterfeit auto parts do not meet federal safety standards.

Counterfeiting hurts manufacturers in many ways. Analysts estimate that,in the United States alone,annual revenue loss runs from$6 billion to$8 billion. Perhaps even worse,consumers blame the innocent manufacturers when they unknowingly buy a counterfeit product and find it doesn't perform as expected. Sometimes entire economies can suffer. For instance, when farmers in Kenya and Zaire used counterfeit fertilizers, both countries lost most crops.

By copying other firms' products, counterfeiters avoid research and development costs and most marketing costs. High-tech products such as computers and their software products are especially easy to suffer. As long as counterfeiting is profitable,large quantities of products are available to copy,and the laws are difficult to enforce,counterfeiters can be expected to exist for a long time.

(   ) 1. The word "counterfeiting" most probably means        ,

(   ) 2.The quality of most counterfeit products is        .

     A.   not up to the standards of America
