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.

  An important part of children's cognitive(認(rèn)知) development is created by having them use their imaginations. Before TVs and computers were invented,children had to use their imagina?tions rather than rely on those types of stimulus(剌激) .

  Studies show that children who have imaginary friends are more likely to be more creative and better able to solve problems. Instead of criticizing them for it,encourage it.

  As it turns out,the things that you are able to do for free with your children are also some of the best for them like engaging them in creativity. A box of crayons, some paper,and a little coaching from you will go a long way. Don't judge so quickly. Just like creativity in adults, having a lot of unfiltered ideas is better than holding back on your freedom of expression. Give a kid some art supplies and you will be amazed at what they will come up with. Common house?hold items and things pulled out of the closet can turn into anything your child can dream up in their imagination.

  Fostering(培養(yǎng)) imagination is important because children need to learn how to solve their own problems instead of having their mom or dad always solve them for them. They need to strengthen those problem-solving skills,which will serve them well their whole lives. By letting children solve their own problems, they are less likely to have to depend on others when they grow up. They will be able to solve their own problems. They are less likely to become passive and let others dictate to them. They are better able to think through different scenarios(場(chǎng)景) and outcomes.

  To prepare for life in the real world, children should practice in the imaginary one to better help them cope. Putting them into " what if" situations gives them the tools they will need when

they go into the real world and are faced with real world problems to solve. 

(   ) 5. We learn from the first paragraph that .

   A.children use much of their imagination watching TV and using computers

   B.children who watch TV or use computers have less imagination

   C.children had little imagination before TVs and computers were invented

   D.children can rely on TVs and computers to foster their imagination 

(   ) 6. We can infer from the third paragraph that .

   A.we can use common things to foster children's imagination

   B.art supplies are the best tools to foster children's imagination

   C.we have to choose things carefully to foster children's imagination

   D.we should have freedom of expression to foster children's imagination 

(   ) 7. We should foster children's imagination because         .

   A.it can help them create useful things

   B.it can help them enjoy their lives

   C.it can help them think of different scenarios and outcomes

   D.it can help them solve problems independently

(   ) 8. The underlined "it" in the second paragraph refers to         .

   A.children's ability to solve problems

   B.children's imagination

   C.children's cognitive development

   D.children's having imaginary friends
