Step I Warming up
T: There are many outstanding scientists in the world, who made great contributions to society and science. 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.
S: Thomas Alva Edison is famous for the invention of the light bulb.
(Bb) Scientists Contributions
Charles Darwin The Theory of Evolution
Albert Einstein The Theory of Relativity
…
T: Well done. I think you are all interested in science and scientists. What do you think makes a successful scientist? Have a discussion in pairs or groups of four. Then report the results of your discussion.
S: I think it is the way he uses his tools that makes a successful scientist.
S: I think a successful scientist must have much imagination and intelligence and he must be creative and hard-working.
S: I think a successful scientist must be confident, curious and careful. But what I like to know is what made him/her interested in science.
T: Now look at the photos on the screen. And tell me who they are.
S: They are Einstein, Madame Curie and Edison.
T: Good. They are all very famous in the world. You must have read some quotes from them. For example, never leave that until tomorrow, which is from Benjamin Franklin. Now look at the quotes on the screen. Whom do you think these quotes from and do you know what they mean?
S：I think it is from Edison. It means that if we make great efforts to do sth, we’ll succeed. And no matter how clever he is, a person will fail if he doesn’t try his best. 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?
S: Yes.
S: It is from Einstein. It means if you want to succeed, it’s more important for you to have imagination than knowledge. In Chinese, it means 想象力比知识更重要。
S: It is from Madame Curie. It means there are only things to be understood in the world, while there is nothing to be feared. In Chinese, it means 生活中没有什么可怕的东西，只有需要理解的东西。
T: Do you know any other quotes about science and thinking?
S: Wisdom is only found in truth. -- Johann Wolfgang von Goethe.
S: Knowledge is power. –Francis Bacon.
Step II Listening
T: OK. Now lets do some listening practice on P2. We are going to listen to the descriptions of some famous scientists. Read the requirements by yourselves quickly. Listen to the tape for the first time to get a general idea, and then try to finish the exx.
Step III Speaking
T: Now let’s look at the speaking part on P2. Work in groups of five. Each group member represents a branch of science, eg 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 to debate. You can use the expressions.
S: I think biology is the most important because it is essential to protecting the ecological balance and environment. People can’t live without living things. And it goes hand in hand with our life. If there is no science of biology, there would not be medicine.
S: Well, maybe, but I think that chemistry is the most important. Because it is the key to the progress of the human being. Besides, it is chemical reaction that produces many new things.
S: It’s 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.
S: That’s true. But maths is the basic science. You can’t learn physics or chemistry well without a good knowledge of maths. It is a tool in science and engineering.
S: Well, there is no doubt that maths is an important. In my opinion, computer science is the most important 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.

T: According to Hawking, how do people misunderstand science?
S: According to Hawking, people often think that science is a number of “true” facts and never changes.
T: What are the basic steps of the scientific method?
S: First, scientists observe what they are interested in. To explain what they have seen, they build a theory about how things happen and the causes and effects. Finally, the scientists test the theory to see if it matches what they have seen and if it can predict future events.
T: What is it that Hawking doesn’t like about his speech computer?
S: Hawking doesn’t like his speech computer giving him an American accent.
T: OK. Now you have understood the detailed information. Please pick out the phrases or the sentences that you don’t understand. First have a discussion with your partner and exchange your different points. Then I’ll explain some language points to you.

S: We should have a strong will whatever we do. We should have an indomitable spirit when we want to achieve great success. As long as we have this spirit, we can do it successfully no matter what we want to.
Step II Word Study
T: Now let’s have a dictation of some words.
T: OK. Now let’s do an ex to see how to explain some words in English, according to the meanings of the sentences. Please turn to P5. Let’s do the ex in Word Study. Choose the closest meaning to the underlined word in each sentence. First we’ll learn a new phrase: use up. Do it by yourself and you can discuss in pairs.
Step III Grammar
Bb:1. He hoped to visit China again .
2. It took a lot of time to finish the report .
3. Please give the boy sth to play with .
4. He went home to see his sick mother .
5. Her wish is to become a pop singer .
T: Tell me the function of the underlined part in each sentence.
S: No.1 is used as the object.
S: No.2 is used as the subject. It is more usual to use formal subject “it” and the infinitive phrase is usually placed at the end of the sentence, that is “it is…to do sth.”.
S: No.3 is used as the attribute.
S: No.4 is used as the adverbial for purpose.
S: No.5 is used as the predicative.
T: Now let’s do an ex on the screen. Group the infinitives according to how they are used.
1.Some things need (1) to be believed (2) to be seen .
2.The doctor told him that he may not have more than twelve months (3) to live .
3.(4) In order to get married ,I needed a job, and (5) in order to get a job , I needed a PhD.

S: Subject:(8)
Attribute(2)(3)
Object(1)(9)
Adverbial(4)(5)(6)(7)(10)
Step IV Practice
T: Now let’s do some exercises on P6, Ex2 and Ex3.Rewrite the sentences with “to be done” or “to have been done”.
He wanted the nurses to take care of the patient.
—He wanted the patient to be taken care of.
Because “the patient” is the logical object of “take care of”, the passive infinitive should be used in the second sentence.
The car was reported to have been stolen.
But when the action expressed by the Infinitive happens before the predicate, the perfect infinitive should be used.
Step V Consolidation
T: Now look at the pictures. Who can tell me what Hawking’s dream is from the picture?
S: He wants to get married.
T: Right. Do you know how Hawking made his dream come true according to the passage we learnt in the second period?
