Some quotes from famous scientists: 1. Genius is one percent inspiration and ninety-nine percent perspiration. 2. Imagination is more important than knowledge. 3. Nothing in the world is to be feared; it is on!y to be understood: T: Whom do you think these quotes are from and do you know what they mean? Discuss these questions in groups of four and tell us whether you agree with what they said. You’re given five minutes to have your discussion. (Teacher may go among the students and join them in their discussion.) T: (Five minutes later.) What’s the meaning of the first quote, Wu Liping? S: I think it means that if we make great efforts to do something, we'll succeed. And no matter how clever he is, a person will fail if he doesn’t try his best. T: Very good. Who do you think said this quote? S: I think it was Thomas Alva Edison who said it. In Chinese, it means“天才就是百分之九十九的汗水加上百分之一的灵感” T: Do you agree with it? Ss: Yes. (Teacher asks two other students to explain the other quotes and tell who said them.) S. “想象力比知识更重要”。(Albert Einstein) If you want to succeed, it's more important for you to have imagination than knowledge. S:生活中没有什么可怕的东西，只有需要理解的东西。(Maria Curie) There are only things to be understood in the world, while there is nothing to be feared. T: Do you know any other quotes about science and thinking? (One student stands up.) S: I'd like to have a try. Wisdom is only found in truth.-Johann Wolfgang von Goethe S: Knowledge is power.-Francis Bacon … (Ask the students to open the books at Page 1 and let them have a discussion about the quotes and pictures in Warming up.) T: (A few minutes later.)We have learnt some quotes now. If you want to know more about quotes about science and thinking, you can collect more information in the library or on the Internet after class. Step Ⅲ Listening T: OK. Now let's do some listening practice on Page 2. Today we are going to listen to the descriptions of some famous scientists. Before listening to the tape, please read the requirements by yourself quickly. When I play the tape for the first time, you just listen to get the general idea. The second time I play the tape, you should try to finish the exercise. The last time, check your answers. Are you clear? Ss: Yes. T: OK. Let’s begin. Please listen carefully. (Teacher plays the tape for the students to listen and pauses the tape for the students to write down their answers when necessary. In the end, check the answers with the whole class and give some explanations or play the tape again if necessary. ) Step IV Speaking T: Now let's look at the speaking part on Page 2. Work in groups of five. Each group member represents a branch of science, for example, biology, maths, chemistry, physics, computer science. You are going to debate each other to see which branch of science is the most important and useful for society. First you should decide who will represent each branch and then prepare your role card and them begin to debate. Are you clear? Ss: Yes. T: You can use the expressions at the bottom of this page when you debate each other. They are very helpful. (Five minutes later, teacher checks their debate.) T: Which group would like to give a performance? Please come to the blackboard. (One of the groups come to the blackboard and begin their debate.) S: I think that biology is the most important and useful science because it is essential to protecting the ecological balance and environment. People can’t live without living things. Furthermore, biology goes hand in hand with our life. If there were no science of biology, there would not be medicine. In a word, biology is the most important and useful. S: Well, maybe, but I think that chemistry is the most important and useful, because chemistry is the key to the progress of the human being. Besides, it is chemical reaction that produces many new things. S: It is hard to say. There are many physical products. And physics is widely used in many fields, such as medicine, industry and agriculture. There would be no life without physics. So I think physics is the most important and useful science. S: That's true. But maths is the basic science. You can't learn physics or chemistry well without a good knowledge of maths. Maths is a tool in science and engineering. Therefore, maths is the most important and useful science. What's your idea? S: Well, there is no doubt that maths is an important and useful science. In my opinion, the most important and useful science should be computer science in our modern information society. The computer is now an indispensable tool in many fields. It can settle all kinds of problems at a high speed and can help people work easily. So I think computer science is the most important and useful science. Step V Summary and Homework T: Today we've done some listening and speaking. We have also talked about science and scientists. After class, please search more information about science and scientists on the Internet or in the library. And don't forget to preview the reading material “No Boundaries”. So much for today. Class is over.
