Background Information The 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 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. His 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 he must use a wheelchair and other technical aids to do things, his brain functions perfectly. Indeed, it functions better than the vast majority of people’s. So, in sprite of a severe disability, he has made tremendous contributions to our understanding of our universe. So what does Stephen think about 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 view 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 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 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. 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 Newton, in 1663. It may be that the name Hawking just as well known in history as that of his famous predecessor. The First Period I. Teaching Aims: 1.

Ss: Good morning, Miss Wang. Step2 Warming Up T: 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 while, I’ll 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 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 results 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 working. 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 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 don’t know him that much. T: Alfred North Whitehead (1861-1947) was a British philosopher and mathematician. What does this sentence mean? S: 分析明显的事物需要非凡的头脑。 S: She is Marie Curie. 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 have learnt some quotes, do you know any other quotes? S: Knowledge is power. – Francis Bacon. T: Good, so much for warming up. Now let’s move on to listening. Step2 Listening T: Ok, now let’s do some listening practice on Page2. Today we are going to listen to some descriptions of some famous scientists. Before we start to listen to the material, let’s read the requirement together and go through some new words. (Read the requirement and questions as well as put some new words on the blackboard—agriculture, gravity, radioactivity, curious.) T: Ok. Let’s begin. Please listen carefully. (Teacher plays the 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 known 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, maths… T: Yes, the science we usually mean is physics, chemistry, biology, maths and computer science nowadays. Now I have a question for 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: physics, 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. (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 don’t live with good environment. So to the root biology is a science to protect human beings. What’s 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 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: That’s true, but maths is the basic science. You can learn physics or chemistry well without a good knowledge of maths. Maths is a tool on science and engineering. Therefore, maths is the most important and useful science. S5: My idea is that computer science is the most important and useful science nowadays. As you can see anywhere you go, there is computer. The computer is an indispensable tool in our modern life. It can settle many problems at a high speed and help people work easily. Step5 Language Points T: There are some useful phrases I want you to understand in this part: 1. on fire= be crazy at 2. be know for / be known as Eg: He is known for his first book, which was the best seller for a year. He is known as a children’s book writer. 3. have … in common 4. doubt + if/ whether/ when….; no doubt that Eg: If he keeps missing school, I doubt if he is going to pass his exams. There is no doubt that the plane is going to be canceled because of the bas weather. Step6 Summary and Homework T: today we have done a lot of listening and speaking. We also have learned and talked about some science and famous scientists. After class, please search more about science or scientists you are interested in on the Internet or in the library. Please preview the reading on page3: “No Boundaries”. So much for today.

It took a lot of time to finish the report. 3. Please give the boy something to play with. 4. He went home to see his sick mother. 5. Her wish is to become a pop singer. T: Now look at the sentences on the blackboard. And tell me what these underlined parts are and what function of them in each sentence. S: All the underlined parts are used as the Infinitive. S1: In the sentence one, the Infinitive part is used as the object. S2: In the second sentence, I think “to finish the report” is used as the attributive modifying “time”. T: Do you think he answer is right or wrong? S5: He is wrong. It is used as the subject. It refers “to finish the report”. T: Very well. Now let’s take a look at the third sentence. S3: In the third sentence, I think “to play with” is used as the attributive modifying “something”. T: Is he right or wrong? Ss: Right. T: Great. Let’s see the next sentence. S4: In the fourth sentence, I think “to see his sick mother” is used as the adverbial for purpose. T: Good. Let’s move on to the last sentence. S6: In this sentence, “to become a pop singer” is used as the predicative. T: Now you have known some usages f the infinitive. Let’s do an exercise to practise the usage of the infinitive. Step 5 Practice T: As you can see, the infinitive can not only be used as object and subject but also as attributive, predicative and adverbial. Now please open your books on page 5 and do exercise 1. Group the infinitive according to how they are used. Suggested answers: 1. Subject: (8) 2. Attribute: (3) 3. Predicative: (1), (2) 4. Object: (9) 5. Adverbial: (4)(5)(6)(7)(10) T: Very well. Now turn to page6 and do exercise2. I will give you one minute for this one. And then I will ask some students to read the answers and translate the sentences into Chinese as well. (One minute later, check their answers.) Suggested answers: 1. to be invited; 2. to pass; 3. to consider; 4. to be sent; T: Ok, look at Ex3. Rewrite the following sentences using the infinitive. The example will help you. First do it by yourself. Then discuss it in pairs. Finally I will show you the right answers. Suggested answers: 1. Is there anything to eat? 2. I need a pen to write with. 3. Do you have anything to add? 4. He is looking got a box to put the two rabbits in. 5. It would be a comfortable house to live in. (If the students do not understand the answers, teacher will give more explanation.) T: I think you have understood how to change the sentences into the sentences with the infinitive. Now let’s see more exercises. Turn your books to page 83. And take a look at exercise1 on this page. Rewrite the following sentences with infinitive as subjects. This exercise is very easy. I give you one minute to finish this one and then I will ask some students to give me the answers one by one. (See the answers on page83 of the book.) T: Do you remember before we have learned a phrase: find it …a. to do sth? S: Yes. T: In this phrase, to do sth. is the object of “find”. Now turn over your books and see Ex2. Answer the following questions with find it … to …. Two minutes for you to finish this exercise. (Two minutes later check the answers to these questions. See suggested answers on page 83.) Step 6 Consolidation T: Now look at the picture. 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? S: Hawking said, “In order to get married, I need a job, I need a job and in order to get a job, I need a PhD.” T: Very good. Now let’s look at another picture. And tell me what the girl’s dream is and how she makes it realized. T: Who can tell us the girl’s dream and how she can realize it? S: I would like to. Her dream is to get a doctor’s degree. In order to get a doctor’s degree, she needs to go to university; she needs to study hard now. T: Very good. Now please tell your partner what your dream is and how to realize it. You can use “in order to” to express it. (Teacher gives the students two minutes to talk freely.) Step 6 Summary and Homework T: Ok.

He is known as a famous writer. T: Good. Today we will review the Infinitive. First let’s do an exercise. Fill in the blanks with the best answer. (Show the exercise on the screen.) Choose the best answers: 1. We agreed _____ here bit so fat she has not turned up yet. A. having meet B. meeting C. to meet D. to have met 2. The boy wanted to ride his bicycle in the street, but his mother told him _____. A. not to B. not to do C. not do it D. do not to 3. When I handed the report to john, he said that George was the person _____. A. send to B. for sending it C. to send it to D. for sending it to T: Now look at the screen. I’ll ask three of you to tell the answers one by one. Any volunteers? S1: The first answer is C. S2: The second answer is A. S3: The third answer is C. T: Well done! Sit down please. Who can tell me the function of each infinitive in the three sentences? S4: I can. … Suggested answers: 1. Object 2. Object complement 3. Attributive Step 3 Explanation and summary T: As we all know, the infinitive is used as the object of the verb “agree” in the first sentence. Now can you think of any other verbs followed by the infinitive as their objects? Ss: Afford, arrange, ask, beg, choose, decide, expect, fail, hope, manage, offer, pretend, promise, refuse, want, wish and so on. (Write them on the blackboard.) T: very good. there are some verbs followed by either the infinitive or the doing. Do you know what they are? Ss: like begin, continue, forget, regret, remember, start, stop, try… T: Right. But attention please. The verbs “begin, continue, start, like, love” can be followed by either the infinitive or the doing form. And they have ht same meaning. While the verbs “forget, regret, remember, stop, try” can also be followed by the infinitive or the doing form. There are some differences between them. Now look at the examples on the screen. (Show the screen.) 1. I like playing football, but I don’t like to play it now. 2. I remember seeing her once somewhere. 3. I must remember to take my notebooks with me. T: From the first sentence, we know the doing form is an action in general while the infinitive is an action on a certain occasion. In the second and the third sentences, the doing form is used for a past event while the infinitive is used for a future action. Are you clear? Ss: Yes. T: Please translate the sentences into Chinese, one student, one sentence. S1: 我喜欢踢足球， 但是现在不愿意。 S2: 我记得在哪里见过她。 S3: 我必须记住带上笔记本。 T: Good. When the infinitive is used as object and is followed by object complement, we often use this structure: S. + V. + it + adj./n. + infinitive. Now please make some sentences with the structure. S4: I thought it unnecessary to argue with him about it. S5: He confiders it his duty to help others. T: Very good. Which verbs do you think can be followed by the infinitive as object complement? Ss: advise, allow, ask, want, wish, order, tell, have, make, feel, hear, watch, see… T: Yes. Some verbs, like “advise, allow, ask, want, wish…” must be followed by the infinitive with “to”, while the verbs “have, let, make, feel, hear, watch, see…” must be followed by the infinitive without “to”. But you must not forget “to” in the passive voice. Look at the examples on the screen. (Show the screen.) 1. We often hear her ding the folk song. =She is often heard to sing the folk song. 2. The girl wanted to go dancing, but her mother told her not to. T: In the second sentence, “not” is put before the infinitive. To avoid repetition, the verb after the sign “to” is often omitted. But “to” can not be left out. This is done after such verbs as: want, wish, like, love, hope, plan, try, hate etc. now look at the examples on the screen. (Show the screen.) 1. –Would you like to come to a party?-- I d like to. 2. –Have you listened to the music? -- No, but I plan to. 3. You don’t have to eat it if you don’t want to. T: When the infinitive or the infinitive phrase is used as subject, the formal subject “it” is often used, that is, “it is +n./adj.+ infinitive”. If we need to tell who performs the action of the infinitive, we cab put “for sb.” before the infinitive. Some adjectives, such as, kind, good, wise, stupid, foolish, careless, clever…, must be followed by “of sb. to do sth”. In this case, the sentences emphasizes “person”. If we use “for sb to do sth”, it emphasizes thing. Please look at the sentences on the screen and compare them, then fill in the blanks with “of” or “for”. (Show the exercise on the screen.) 1. It is silly ____ us to believe her. 2. It is impossible ____ her to finish the task so soon. 3. It is nice _____ you to help me. 4. It is necessary ______ us to take exercise. (Teacher asks four students to give the answers.) Suggested answers: 1. of 2. for 3. of 4. for T: Now look at the sentences on the screen. Pay attention to the forms of the infinitive in the sentences. 1. She asked to be sent to work in Tibet. 2. I am glad to have seen your mother. 3. We did not expect you to be waiting for us here. T: In the first sentence, the passive infinitive is used, which expresses a passive action. In the second sentence, we use the perfect infinitive. When do you think the perfect infinitive is used? Ss: When the action expressed by the infinitive happens before the predicate, the perfect infinitive should be used. T: Quite right, now look at the third sentence. The continous form of the infinitive is used. When the action is happening, we use theh continous form of the infinitive. (to be done, to have done, to be doing) Now let’s do an exercise: (Show ht eexercise on the screen.) 1. I have two letters ______ today. 2. I have no letters ______ today, thank you.A. to type B. to be typed3. I would like to ______ to the cinema tonight. 4. I would like to ______ to the cinema last night. A. go B. have gone5. When his mother cane in, the little boy just pretended ______. A. to read B. to have readC. to be read D. to be reading Suggested answers: 1. A 2. B 3. A 4. B 5. D T: Besides, the infinitive can also be used as predicate, attribute, adverbial for purpose and for a disappointing sequel. Now look at the sentences on the screen. Pay attention to the usages of the infinitive. 1. He does not seem to like the idea. 2. The boy uses a computer to play games. 3. She hurried to the station only to find the train had gone. 4. There are letters to be typed. 5. I have nothing to do. 6. Please pass me a pen to write with. T: In the last two sentences, the meaning is passive, but the active infinitive is used. You must pay attention to it. Step 4 Practice and Consolidation T: Now you have known all about the infinitive. Let’s do some exercises to have a consolidation so that we can use it correctly. Please look at the screen. Fill in the blanks with the proper forms of verbs:1. He hopes _____ (invite) to the party. 2. My wish is ______ (become) an engineer. 3.
