　　step ii warming up
　　ask some ss to tell us what scientific achievements they think have changed the world?
　　(teacher writes all the scientific achievements mentioned above on the blackboard and says the following. )
　　step iii listening
　　the listening material contains two parts. you are going to hear some words said by some famous people at the time when they achieved success.
　　look at the chart in exer¬cise 1 at the top of page 2 quickly. then play the first part of the tape for the ss to complete it. after that, check their answers. (after checking the answers to exer¬cise 1, teacher goes on to deal with exercise 2)
　　now, listen to part 2 and complete the sentences in exercise 2, if necessary, play it twice for ss to finish or check their answers.
　　at last, teacher deals with exercise 3.
　　step iv speaking
　　here are four scientists who want to get money to complete their project. each scientist will have to introduce his or her project and explain why it is the most important. now, the teacher put the students in groups of five to have a discussion. four group members represent scien¬tists tone member will listen to all the scientists and ask questions. at the end of the discussion, he or she must decide who will get the money and why..
　　(teacher and the students go through the expressions. after that, teacher puts the students in groups of five and gets them to prepare for a few mi¬nutes. at the end, teacher asks one or two groups to report their work to the rest of the class. )
　　a sample dialogue;
　　organizer: now, everybody is here. who＂d like to be the first to make a statement on this project? dr wilson: i and my team are working on a cure for aids. as you know, the number of people
　　infected with aids is keeping increasing at an astonishing speed. some of them are facing death. as a result, we have to find a way to solve this prob¬lem as soon as possible. but, right now, the lack of money is a big problem. if we got enough money, we would com¬plete the first stage of our pro¬ject in the near future.
　　organizer: i see. dr jones, how about you?
　　dr jones: at present, we are also facing the same problem of lacking money. my research project is about cloning and how to use new technology to cure dis¬ease. today, more and more patients are expecting to get organ transplant in order to prolong their lives. i wish what i am doing could help them.
　　organizer: i understand. dr smith, could you please give me your opin¬ions on your project?
　　dr smith: for humankind on the earth, food is a fundamental factor, and as the population keeps growing, per capitation resource of people is becoming less and less. my plan is to de¬velop new technology that will make it possible to grow food with very little water. howev¬er, currently, the shortage of money prevents my work from further going. i hope you can give me a hand on my project,
　　organizer: it sounds a good idea. dr winfrey, it＂s your turn now.
　　dr winfrey: it’s ceaseless for human be¬ings to explore the universe. that＂s why we are urgent to know what the mars looks like and if there is any life on it. i＂m thinking of sending a man¬ned spaceship to mars. never¬theless, this huge project will surely cost a large sum of money. and i don＂t think we can get to the aim without your support.
　　organizer: so, everyone has finished their statements on their own pro¬ject. frankly speaking, they all sound tempting to me, but i＂m more inclined to the project suggested by dr smith. from my point of view, it＂s more closely related to the daily life of people and in accord with the actual condition of our country. i＂d like to pour money into his project.

　　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.
