the new centre for Chinese science and technology.The centre itself got started in the early 1980s and was set up as a special economic zone in the late 1990s.Then it quickly became the leader of Chinas hi-tech industry.A growing number of overseas have returned to China and grasped the opportunity to develop their ideas at Zhongguancun.Zhongguancun has had a positive effect on business as well as science.Today,there are more than 8 000 hi-tech panies in Zhongguancun,more than half of which are IT panies.What has made Zhongguancun a success is the spirit of creativity and scientific skill.T:Very good.Thank you.Sit down,please.We all know Zhongguancun is the leader of Chinas hi-tech industry as Silicon Valley in the USA.So sometimes it is called Chinas Silicon Valley.In the last class,I asked you to use a library or the Internet to find out more about Silicon Valley and then pare the two areas.Now whod like to tell us how similar or different they are?Any volunteer?S2:Both Zhongguancun and Silicon Valley are home to Internet industry as well as hi-tech panies,most of which are founded by students,faculty and staff members from the surrounding universities.However,as a fledgling hi-tech munity,Zhongguancun has many differences from Silicon Valley.Silicon Valley has evolved a culture that is tuned to market-driven innovation,while in Zhongguancun,innovation is still largely driven by technology.In addition,investors in Silicon Valley are frequently an integral parts of panies day-to-day operations.While in Zhongguancun,investors has been used only as a source of
