Now work in pairs.Step III TalkingSa: There is no doubt that the second one is Madam Curie who was born in Poland and later took the French nationality. She is best well-known for discovering the radioactive elementpolonium named in honor of her motherland in 1898.Sb: Yes. She was a great woman scientist and the only person to win Nobel Prizes twice.Sa: She is respected and admired by people all over the world because she would like to share her discoveries with the whole scientific world. I read in a book that Madam Curie encouraged the usage of X-rays for medical treatment.Sc: I can recognize the fourth figure is Elbert Einstein, as Einsteins shaggy-haired face was very familiar to ordinary people. He was born in Germany on March 14th, 1879. And his most famous theory is relativity that was first published in 1905.Sd: Yes. You are quite right. But I dont know who the first scientist is.

Its said that the great scientist led a very simple life. He set a good example for all Chinese. His devotion to science and his patriotic feeling make him not only a great scientist but also a great man.T: Thank you very much. You have done a very good job!Would you like to know something about the third scientist?Ss: Of course! T: Now listen to me carefully. His most famous saying is “Give me a lever(杠杆) long enough and a place to stand, and I will move the world.” Who can tell us his name?Se: Archimedes! A great mathematician!T: Quite right! Who can talk more about him?S1: He was also considered to be a great physicist. And there was a famous story about how he discovered buoyancy (浮力) when the king asked him to tell if the gold crown was a pure one. Archimedes did in fact use some very practical methods to discover results from pure geometry （几何学）.S2: The achievements of Archimedes are quite outstanding. He is considered by most historians of mathematics as one of the greatest mathematicians of all time. Archimedes was killed in 212 BC by the Romans in the Second Punic War. S3: He perfected a method of integration that allowed him to find areas, volumes and surface areas of many bodies.T: OK. Now, its time for you to talk more about them with your partners. What can we learn from them? And then you are to complete the table on the screen.

He made distinguished contributions to the foundation and development of Chinese aerospace undertaking.T: Any other facts about Qian?S2: Qian Xuesen graduated form Shanghai Jiao Tong University in 1934. One year later, he went to the USA and continued his studies in MIT (Massachusetts Institute of Technology), after receiving masters degree in MIT, Qian went to study in California Institute of Technology. In 1955, six years later after the founding of New China, Qian Xuesen returned to the motherland.T: Well done! You knew so much about him. Maybe you would like to be a great scientist like him. Yes? OK. How about the next one?S3: Madame Curie was born in Poland in 1867. She studied physics in Paris and discovered radioactivity. She is remembered for her determination and courage, her willingness to share her knowledge, her medical service during the war. S4: Madame Curie and her husband were given the Nobel Prize in Physics in 1903. And in 1911 she received a second Nobel Prize for her research. She died of cancer in 1934.T: How about the third scientist Archimedes?S5: Archimedes was a native of Sicily in 287 BC. He is considered by most historians in mathematics as one of the greatest mathematicians all the time. S6: Archimedes was killed in 212 BC by a Roman soldier, running upon him with a drawn sword.T: The last one Albert Einstein.S7: Albert Einstein was born in Germany, 1879. He first had the idea of his theory of relativity when he was 16.S8: Albert Einstein was given the Nobel Prize for physics in 1921.

Id like you to give your answers and give the discussions about the Great scientists. Try to speak it out freely and frankly for the class.S1: Charles Darwin was born in Shrewsbury in February, 1809. In 1837 he began the first notebook on “Transmutation of Species”. He began further notebooks on man and materialism in July, 1838.In September he first formulated theory of evolution by natural selection. In March, 1859 Charles Darwin finished the writing Origin of Species.S2: Samuel C.C. TingAutobiography was born on 27 January 1936 in Michigan, America. Two months after his birth his family returned to China. On 6, September, 1956 with $100 he went to America for further study. There on the fall of 1974 he found evidence of a new, totally unpredicted, heavy particlethe J particle. Since then a whole family of new particles has been found.S3: When David Ho was three years old his father traveled to America in search of a better life for his family. Realizing that AIDS was an infectious disease and that HIV multiplies many times right from the start, Ho and his team administered a combination of protease-inhibitor and antiviral drug “cocktails” to early-stage AIDS patients with dramatic results.S4: Hawking has a disease that progressively weakens muscle control. Hes also a best-selling author. His book, A Brief History of Time, has been translated into 33 languages and has sold nine million copies.The Big Bang theory has its limitations. Scientists are searching for a “theory of everything” a quantum gravity theory that would unify the general theory of relativity and quantum mechanics theory.A Brief History of Time has been translated into 33 languages and has sold nine million copies.Step VI VocabularyIf time permits, ask the Ss to do Part 2 in class; or leave it as homework.Step VII Homework1.
