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 Exercise 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 Exercise 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 V Summary and Homework
T. In this class, we've mainly talked about scientific achievement. Centering on this topic, we did some listening and speaking. This way, we've learnt more about science and scientific achievement. Moreover, we've learnt some useful expressions to express intentions and wishes, .such as ”If I got the money, I would……; My plan is to…… (Teacher writes them on the blackboard. ) After class, try to practise using them and preview the reading part.
Step VI The Design of the Writing on the Blackboard

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 scientists 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 minutes. 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 problem as soon as possible. But, right now, the lack of money is a big problem. If we got enough money, we would complete the first stage of our project 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 disease. 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 opinions 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 develop new technology that will make it possible to grow food with very little water. However, 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 beings 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 manned spaceship to Mars. Nevertheless, 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 project. 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.
