3、动了物理学理论的革命，他对社会进步事业也有重要贡献。步事业也有重要贡献。霍金霍金 born in 1942 斯蒂芬斯蒂芬藿金藿金是当今科学界的一位是当今科学界的一位传奇性人物。这不仅仅因为他是一位传奇性人物。这不仅仅因为他是一位被誉为继爱因斯坦后最著名的科学思被誉为继爱因斯坦后最著名的科学思想家和最杰出的理论物理学家，还在想家和最杰出的理论物理学家，还在于他是在常人无法想象的身体状况下于他是在常人无法想象的身体状况下进行研究和创造性工作的。进行研究和创造性工作的。black hole 黑洞黑洞 黑洞黑洞并非只是吞噬物质。除了会在星并非只是吞噬物质。除了会在星系形成的过程中扮演重要角色外，在经过

4、系形成的过程中扮演重要角色外，在经过一段相当漫长的时间后，黑洞也会把一些一段相当漫长的时间后，黑洞也会把一些曾被它吸入的物质信息向外界释放出来。曾被它吸入的物质信息向外界释放出来。Now were going to listen to a talk about the theories of gravity.Listen carefully and try to get the main idea of it.Listening Summary B is correct because it gives a clear idea of what the listening passage is

5、 about.Summary A is not true.The three scientists wanted to explain how the universe worked and not how it began.Summary C is too general and does not give enough detail about what the listening passage is about.Choose the best summary.Listen to Part 1 again and fill in the first column of the chart

6、.Isaac NewtonAlbert EinsteinStephen HawkingIdea Large bodies have a force which pulls things towards themIn space large objects make space and time bend;the larger the object,the further space and time bendsBlack holes have a very large mass and pull things towards them towards their edge.Isaac Newt

7、onAlbert EinsteinStephen HawkingDevelopment The bigger the object the stronger the gravity.Time goes slower in very strong gravity.If you go over the edge,you cannot get out;but if you do not,you may be able to escape.Listening on P62Work in groups of four to discuss the Questions.What education and

8、 experience do you need to become an astronaut?Do you think there are any special requirements?What kind of a person makes a good astronaut?What problems do you think he/she would have in space?杨利伟，男，汉族，辽宁绥中县人，中共党员，杨利伟，男，汉族，辽宁绥中县人，中共党员，大学文化。大学文化。1965年年6月出生，月出生，1983年年6月入伍，月入伍，1988年年9月入党，现为中国人民解放军航天员大

9、月入党，现为中国人民解放军航天员大队三级航天员，正团职，中校军衔，队三级航天员，正团职，中校军衔，1992年、年、1994年两次荣立三等功。年两次荣立三等功。He went up into space on October 15th,2003.Where were you when you heard about the successful launch?How did you feelListeningListen to the tape and write down the main idea.The main idea is the excitement of space travel

10、 and the qualifications and experience needed to become an astronaut.Listen to the Part 1 again and make notes of the answers to the questions.Attention!Taking notes means writing phrases and not complete sentences.Questions Yang Liweis answersWhen was the most exciting moment?What surprised him?Wha

11、t did he do?When his spaceship lifted off the ground he knew he was really on his way into space.The beauty of space.He watched all his instruments and stayed calm.Information on Yang LiweiEducation Training Physical qualitiesPersonal qualitiesHe got his degree.He trained for ten years to fly airpla

12、nes and then to fly a spaceship.Smaller than 170cm,less than 70kgCalm,mature,hard-workingListen to the Part 2 and fill in the form.keys for exercise 5:dreamed,young,wish,true,gradually,opportunity,loveTrue or False according to the listening text.1.Yang Liwei became an astronaut by chance.2.Nobody o

13、ver 170cm can be an astronaut.3.Yang Liwei trained for 10 years to become a pilot.FFTListening task Pre-listeningWhat do you know of the problems of making a space walk.Make a list with your partner.Listen to the tape and check if you are right.oxygen canGravity boots Water systemRight engineTool ki

14、t Left engine1.Why did Li Yanping have to repair the Hubble telescope?It needed cleaning so that it would work better.2.Which two ways does his spacesuit protect him in space?1)It carries oxygen.2)It carries hot and cold water to warm him if its too cold and cool him if its too hot.Listen to the tap

15、e again and answer the questions.3.How does he move about in space?He used small engines.4.What does it feel like in space?Strange because you do not weigh anything.You can fly around like feathers.5.What happens if you fly too far from the spaceship?You would continue into space and never get back to the spaceship.6.Was the repair successful?Yes.The Hubble telescope works well now.Homework After class,you should listen to them again and sum up what you have learnt from them.For the homework,think about one question:What needs to be an astronaut?
