4.He is good-looking, apart from his nose.?

5.It is announced that the spacecra ft, Shenzhou Ⅵ, landed on the earth successfully.?

6.It is not Tom but you who are to blame.?

7.In 1995, the Chinese government put forward a plan for“rejuvenating the nation by relying on science and education”.And it has helped Chinese scientists make many breakthroughs.?

8.Have you drawn any conclusion after you read this passage?

T: Well done.So much for the learning of the new words and expressions.?

Step 4 Brainstorming

T: Now let’s come to the title of this unit Great scientists.When we talk about great ?scientists, what will come into your mind(s)?We will go on our competition.?

S1: Madame Curie, who got two Nobel Prizes, one for physics and the other for chemistry, is really outstanding among all the women scientists.?

S2: It reminds me of the great inventor named Thomas Alva Edison and one of his famous? sayings“Genius is one percent inspiration and ninety-nine percent perspiration.”

S3: Yes, we lead a better life now with the help of science.Without Edison, maybe now we are still living in a dark world.They really make our life easier and more comfortable.?

S4: I also think of one of the quotes from  Albert Einstein, “Imagination is more important than knowledge.”

S5: All the scientists are devoted to the career that they choose, and they set good examples to us in our work.?

S6: Take all the scientists for example, if we want to be successful in the future, we should not only learn something from our textbooks, but also take part in social practice and get close to nature to learn more about it.?

S7: I like plants very much.I just think of the two key scientists in the field of botany, Carl Linnaeus and Joseph Banks.The former one laid the foundation for the classification of plants, while the latter one also made great contributions to the development and direction of botany.

Ss: ...　?

T: I’m glad to see that you have a great deal of previous knowledge of famous scientists in the world.

Step 5 Previous knowledge

T: Now let’s match some of the great scientists with their famous discoveries, inventions or theories.Let me see who is the quickest in mind and action and can get all the answers correct.?

Famous scientists   Discoveries/Inventions/Theories?

A.Isaac Newton   1.Evolution (进化论)?

B.Charles Darwin   2.Discovery of Radium(镭)?

C.Madame Curie   3.Newton’s Law?

D.Albert Einstein   4.Electric bulb?

E.Thomas Alva Edison  5.Theory of Relativity?

F.Nicolaus Copernicus  6.Seismograph?

G.Stephen Hawking   7.A Brief History of Time?

H.Zhang Heng    8.The earth moves around the sun.?

(Check the answers with all the students: A—3, B—1, C—2, D—5, E—4, F—8, G—7, H—6.)

T: Since you have a better understanding of some of the great scientists, let’s play a game. Please work in groups and describe one of the great scientists, and then let other students guess who you are talking about.?

Group 1: In the eighteenth century, there lived a great scientist who conducted a number of experiments in which he showed what electricity is.Once he did a famous kite experiment on a stormy day, and proved that lightening and electricity are the same thing.?

S: Benjamin Franklin.

Group 2: It is said that this English gentleman was sitting in his garden one day when suddenly he was hit by a falling apple.The story is probably not true, but this man did mention that he got one of his best-known ideas while watching apples fall from a tree.His name makes you think that he was not too interested in old things.He ?discovered? the force of gravity, and he drew up a system of how objects move.His laws for motion are still used in physics today, at least in schools and universities.?

S: Sir Issac Newton.

Group 3: Food is what sets this great mind on fire.Rice, to be exact.This great mind has spent most of his life looking for ways to help farmers grow more rice so that all of us will have enough food to eat.He is known as the father of modern rice, but because of his long friendship with all the farmers in China, he would rather be known as“the farmer”.?

S: Yuan Longping.?

Group 4: He was born on 8 January 1942 in Oxford, England.He has worked on the basic laws which govern the universe.He showed that Einstein’s General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes.He has three pop ular books published: his best seller A Brief History of Time, Black Holes and Baby Universes and Other Essays and most recently in 2001, The Universe in a Nutshell.?
