step ii revision
in the last period, we read the passage zhongguancun and learned much about it. now, who can tell me something about it? get some ss to try it.
zhongguancun, in beijing\'s haidian district, is 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 be¬came the leader of china\'s hi-tech in¬dustry. 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 companies in zhong¬guancun, more than half of which are it companies. what has made zhong¬guancun a success is the spirit of crea¬tivity and scientific skill.
we all know zhongguancun is the leader of china\'s hi-tech industry as silicon valley in the usa. so some¬times it is called china\'s silicon val¬ley. in the last class, i asked you to use a library or the internet to find out more about silicon valley and then compare the two areas. now who\'d like to tell us how similar or different they are?
both zhongguancun and silicon valley are home to internet industry as well as hi-tech companies, most of which are founded by students, faculty and staff members from the surrounding universities. however* as a fledgling hi-tech community, 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 addi¬tion, investors in silicon valley are fre¬quently an integral parts of companies day-to-day operations. while in zhong¬guancun. investors has been used only as a source of financing.
