2、our periodsIII. Background InformationThe Beginning of Time and a Remarkable Man Called Stephen Hawking If you have even thought about how the universe began and whether time has a beginning or an ending, then you should know about a 55-year-old Englishman called Stephen Hawking. Why? Because he is

3、considered to be one of the brainiest men in the world and to be the modern successor of Albert Einstein. Stephen has spent his life studying and thinking about the origins f the universe and how it can be explained by using the modern theories of physics such as relativity and quantum mechanics. Hi

4、s discoveries and his scientific proposals have been revolutionary. People call him a genius. Just as amazing is the fast that since his early twenties, he has been suffering from an incurable disease of the nervous system which has affected his movements and his speech. But, fortunately, although h

5、e must use a wheelchair and other technical aids to do things, his brain functions perfectly. Indeed, it functions better than the vast majority of peoples. So, in sprite of a severe disability, he has made tremendous contributions to our understanding of our universe. So what does Stephen think abo

6、ut the beginning of our world? Well, he thinks that it began around fifteen billion years ago. He also thinks that our universe was probably created by an enormous explosion, a “Big Bang”. This is a view held by many cosmologists (scientists who study the universe). But scientists hold different vie

7、w about what the universe was like before the Big Bang. Some people think that there is no way that modern physics can explain or predict anything before the Big Bang. Many other people think that the Big Bang must have been the work of God. Stephen Hawking has his own view on what the universe was

8、like before the big bang. He has suggested that, yes, we can say that the universe began at one particular point (a big bang). But, this one point was just an ordinary point in time like, say, the North Pole is a point on the smooth surface of the earth. It was not a point of real beginning, just a

9、point. Stephen believes that if we can use our present knowledge of the laws of physics to understand how the universe bean, then we will not have to believe that a “God” or a spiritual force made the Big Bang. What do you think about our beginnings? If you would like to read more about Stephens ide

10、as on the origins of the universe, then you should read his best seller A Brief History of Time. In sprite of his difficult illness and his confinement to a wheelchair, Stephen Hawking works as a professor of mathematics at Cambridge, holding the same position held by another famous scientist, Isaac

11、 Newton, in 1663. It may be that the name Hawking just as well known in history as that of his famous predecessor. The First PeriodI. Teaching Aims: 1.

15、gsT: Good morning. Ss: Good morning, Miss Wang. Step2 Warming UpT: There are many outstanding scientists in the world, who made great contributions to society and science. Now please make a list of the names of some scientists and their contributions. Write them down on a piece of paper. After a whi

16、le, Ill collect your answers. (Teacher goes among the students. After a while, collect your answers.)Ss: What great scientists do you know? And what are they famous for? .S: Maria Curie is famous for her discoveries of radium and polonium and Zhang Heng is famous for his seismograph. T: Well done, I

17、 think you are all interested in science and scientists. What do you think makes a successful scientist? Have a discussion and make a list of what you have already known and what you would like to know. Discuss it in pairs or in groups of four. After a while, I will ask some of you to report the res

18、ults of your discussion. (Three minutes later, teacher begins to collect the results of their discussion.)T: Who would like to tell me what makes a successful scientist? Any volunteer? S: I think a successful scientist must have much imagination and intelligence and he must be creative and hard work

19、ing. T: Now open your books on page1, there are some photos of some famous scientists. Look at these pictures and you should try to tell me who they are. T: Look at the photos now. Who is the person in picture1? S: Albert Einstein. T: Look at the sentence under the picture, can you translate it into

20、 Chinese and tell me? S: 想象比知识更重要。天才就是百分之一的灵感加百分之九十九的汗水。 你不能教一个人什么东西， 你只能帮助他去发现他内在的东西。 T: Good. Do you agree with him? S: Yes T: Now look at the picture under pictuer1. Do you know who he is? S: He is Alfred North Whitehead. I dont know him that much. T: Alfred North Whitehead (1861-1947) was a Brit

21、ish philosopher and mathematician. What does this sentence mean? S: 分析明显的事物需要非凡的头脑。T: This sentence means most people dont question the things we take granted, but great scientists will be curious and tend to ask questions that others never think of. Who is in the next picture? S: She is Marie Curie

22、. T: Do you understand the sentence she said? Can you tell me the sentence in Chinese? S: 生活中没有什么可怕的， 只是要去理解他们。T: Look at the photos now. Who is the person in picture4? S: Thomas Alva Edison. T: Look at the sentence under the picture, can you translate it into Chinese and tell me? S: 天才就是百分之一的灵感加百分之

23、九十九的汗水。 T: Good. Do you agree with him? S: Yes T: Look at the photos now. Who is the person in picture5? S: Galileo Galilei. T: Look at the sentence under the picture, can you translate it into Chinese and tell me? S: 你不能教一个人什么东西， 你只能帮助他去发现他内在的东西。 T: Good. Do you agree with him? S: Yes T: Now we hav

24、e learnt some quotes, do you know any other quotes? S: Knowledge is power. Francis Bacon. T: Good, so much for warming up. Now lets move on to listening. Step2 ListeningT: Ok, now lets do some listening practice on Page2. Today we are going to listen to some descriptions of some famous scientists. B

25、efore we start to listen to the material, lets read the requirement together and go through some new words. (Read the requirement and questions as well as put some new words on the blackboardagriculture, gravity, radioactivity, curious.)T: Ok. Lets begin. Please listen carefully. (Teacher plays the

26、tape for the students to listen and pauses the tape for the students to write down answers when necessary. In the end, check the answers with the whole class and give some explanations or play the tape again if necessary.)Step4 Speaking T: From the warming up and listening part, we have already know

27、n a lot of famous scientists in different field of science, or you can say in different branch of science. What science do you know? S: Physics, chemistry, biology, mathsT: Yes, the science we usually mean is physics, chemistry, biology, maths and computer science nowadays. Now I have a question for

28、 you: which branch of science do you think is the most important one? S: (Various answers.)T: On this question you may have different ideas. I want all of you to work in the group of five students and each of you can have your own idea to represent one of the following branches of the science: physi

29、cs, chemistry, biology, maths and computer science. Find reasons to support your view and debate with other students to prove that you are right. Are you clear? S: Yes. T: You can use the expressions at the bottom of page2. They are very useful. Ok, I will give you five minutes to debate. Now begin.

30、 (Teacher checks the students work five minutes later.)Sample debate: S1: I think biology is the most important and useful science because it is essential to protecting nature, environment and ecological balance. People dont live with good environment. So to the root biology is a science to protect

31、human beings. Whats more, no biology means no medicine. So I think biology is the most important science. S2: Well, maybe, but I think that chemistry is the most important and useful, because chemistry id the key to the progress of the human being. Besides, it is chemical reaction that produces many

32、 new things. S3: That is hard to say. There are many physical products. And physics id 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. S4: Thats true, but maths is the basic science. You can learn physics or chemistry well without a good knowledge of maths. Maths is a
