4、dureStep 1 GreetingT: Hello, boys and girls. Ss: Hello, Miss Wang. Step 2 RevisionT: Today we will begin our lesson with a competition between groups. In the last period, we learnt about John Snow who defeats “King Cholera”. Now, please say something that you know about it. If you offer a complete s
5、entence, you will be given ten marks. Your group will be given twenty marks when your expression is especially beautiful. S: John Snow was a well-known doctor in London, who attended Queen Victoria to ease the birth of her babies. S: He became inspired when he thought about helping ordinary people e
6、xposed to cholera, which was the deadly disease of his day. S: John Snow got interested in two theories explaining how cholera killed people. S: He believed in the second theory that is people absorbed this disease into their bodies with their meals. From the stomach the disease attacked the body qu
7、ickly and soon the affected person was dead. Ss: . . . (The teacher should encourage more students to join in the competition. At the end of the competition, the teacher should announce the result of this competition. Praise the winner and encourage the losers. )T: What can we learn from John Show?S
8、: We should base our theories on practice. S: We are inspired to have a spirit of scientific exploration. S: We do some research with the purpose of serving the people and society. Ss: . . . T: Yes, we can learn a lot from the scientist. In fact, there are a great number of people working on science
9、 worthy of being learned both at home and abroad. Can you name some scientists and introduce their main contributions?S: Archimedes, who discovered that objects in water are lifted up by a force that helps them float.S: Darwin wrote a book explaining how animals and plants developed as the environme
10、nt changed. S: Madam Curie discovered radium. S: Stephen Hawking put forward a theory about black holes. S: Zhang Heng invented the earliest instrument to tell people where earthquakes happened.Ss: . . . T: You did a good job and listed many scientists as well as their contributions. Today, we are g
11、oing to learn about more scientists. Step 3 Listening (on Pages 5-6)Task 1 Pre-listeningT: First lets enjoy the picture. What can you see?S: President Jiang Zemin and an old man. T: President Jiang Zemin visited Qian Xuesen. T: What have you already known about Qian Xuesen?S: He is a Chinese scienti
12、st, whose research mainly centers on Physics. S: He is honored as “Chinese Rocket Father”. S: He has made great contributions to space travel in China. T: Good. You seem to have a good knowledge of him. Qian Xuesen is a famous scientist who has contributed much to the countrys cause of science and t
13、echnology. Task 2 First ListeningT: We are to listen to the material, which is about Qian Xuesen. Yu Ping is telling her friend Steve Smith about Qian Xuesens life. If you were Yu Ping, what topics would you like to cover when introducing him?S: The date when he was born and he died;the place where
14、he was born, lived, studied and died;his family;his experience;his achievements;his contributionsT: Excellent. When we talk about and introduce a scientist, we usually describe these aspects. Now, listen carefully and tick out which topics are mentioned in the tape. (After listening, let them check
15、the answers. )Task 3 Second ListeningT: This time. Youll write down the answers to the five questions. Boys and girls, how can we write the answers fast and correctly?S: We should go through the questions first and keep them in mind. When we are listening, we just need to pay much attention to the s
16、entences related to the answers. S: We neednt write down each word of the answers. We just write down some key words. Later we can write down the complete answers with the help of these key words. T: You are clever. Now please get ready. First, look through the introduction to the listening material
17、. Then, scan the questions. (Two minutes later, the teacher plays the tape. Then give Ss time to organize their sentences.)T: Lets check the answers one by one. (If the students make some common mistakes or they seem to have difficulty in finding out answers, teachers can give them some hints and le
18、t them listen to it again. After that, check the answers. If the students feel it difficult to make sense about the key words and understand the speakers intention and attitude, the teacher should give them some help. )Task 4 Post-listeningT: After listening, would you please answer some questions?1
19、 What did you hear on the tape?2 What can you learn from Qian Xuesen?(At this part the teacher may have the students present what they have heard on the tape and show their own opinion about what they have learned from him. If possible, the teacher may have some of the students do the presentation w
20、ork in class. By doing this, the students can get full understanding of what the tape is talking about. )Step 4 Listening (Page 41)Task 1 Pre-listeningT: Just now we learned about a Chinese scientist, Qian Xuesen, who has made great contributions on space travel in China. We will get to know another
21、 scientist, whose contribution is on botany. Can you guess who he is? S: Carl Linnaeus, maybe Darwin. T: You are right. Both scientists did study botany and devoted their time to the research. As we know, Carl Linnaeus developed his system about how to classify species. While Darwin wrote a book on
22、the Original of Species, in which he explained how animals and plants developed as the environment changed. The following is about Carl Linnaeus. T: Now, read the instructions about the listening and choose which of the following statements mist closely describes what this listening passage is about
23、. Explain why the others are wrong. S: I think the third one is right. This is about a man who finds a flower and wants to know if it is a new species of flower. Because he is interested in biology and especially in the study of plants. What he wants to do is to study whether it is a new species. Th
24、e other two statements can not convey the study. Task 2 ListeningT: What you said is reasonable. Lets listen together to find whether your answer is right. (After listening, let them check the answers. )T: Listen to the tape again and try to complete the following passage. To find the name of an unk
25、nown flower, first you have to go to see a flower _he/she will look in a special _written by Carl Linnaeus. He lived in_ from_ to _. He was very important because he solved a serious problem for _. He saw all plants and animals produce _. Some animals produce _but others lay _while plants_. He used
26、these different ways of producing young to put plants and animals into_. For example, the group called birds lay _to produce young and they all have _. Linnaeus put the plants and animals into smaller groups or species. He gave each one two names. One is for the large group, for example _and one is
27、for the species, for example _. So a parrot would be _. He was the first person to successfully classify all plants and animals.Task 3 Post-listeningLet the students fill in the blankets and then check. If the students feel it difficult to do it, let them listen it a third time. After checking the a
28、nswers, ask the students to read it together. Step 5 Listening (Page 44)T: Look at the screen and lets read the following new words firstly. (These words are presented on the screen: analyse, pure, foundation, symbol, sin, cosin, geometry, calculus, mechanics, practical, topology)T: Can you guess wh
29、ich field the next scientist is in according to the new words?S: The next must be a mathematician. T: Right. This mathematician is Leonhard Euler. John Smith is discussing with Zhao Yang his research into the life and work of a mathematician called Leonhard Euler. Listen to the tape and fill in the
30、chart on the importance of Eulers work. Eulers achievementsExamplesNew symbols and termsOld areas of mathematicsNew area of mathematicsImportance(After listening, ask some students to fill in it. If many students feel it difficult, let them listen to it again. While doing it, the teacher can also as
31、k two students to come to write the answers on the blackboard. The teacher had better give them praise if they do it well. )Step 6 SpeakingTask 1 Lead-inT: Boys and girls, from the listening material, we know about some scientists. Do you have a dream to be a scientist in the future?Ss: Yes. /No. T:
32、 Suppose you would like to work as a scientist, and you are discussing with your partner about your future job. What questions would you like to concern?S1: What job do you want to do?S2: How will you get the job?S3: What preparations will you make for the future job?T: Right. Apart from those, we c
33、an also talk about the following questions: 1 What education will you need?2 What personality will be needed?3 What work experience would be useful?4 How long will the training take?5 How will you prepare for this career?T: These expressions may help you: I always wanted to. . . because. . . The exp
34、erience I will need is. . . I might find it difficult to. . . I need to practise. . . My greatest problem will be to. . . I will need to be/become. . . patient, creative, hard-working, co-operative, confident, brave, positive, pleasant, polite, determined, energetic, strict with. . . Task 2 Dialogue
35、 (pair work)T: Now it is time to discuss what scientific job each of you would like to choose in the future with the help of the mentioned questions and expressions in pairs. I will give you five minutes to prepare for it. After that I will let some of pairs to come to act it out. Sample: A: What jo
36、b do you want to do in the future? B: I always want to be a botanist. A: If you want to be a scientist, what education will you need?B: I will try my best to go to a key university to learn and study botany. A: What work experience would be useful?B: The experience I will need is to study wild plant
37、s in the wild when I am at school. Now, I join the social natural club organized by our school. Every time I make every effort to overcome difficulty to study plants in the wild. A: Do you know what personality will be needed if you want to be a scientist in the future?B: I will need to be patient,
38、creative, hard-working, brave, energetic and co-operative. A: Yes, I agree with you. Besides those personalities, we also should be determined, confident and positive. B: I will make efforts to own such good quality. A: How will you prepare for this career?B: I intend to go to college next year and
39、then I will have a chance to be a scientist. But my greatest problem will be whether I will be able to go to university in the future. A: Dont worry about it and just get down to preparing for it. Good chances always belong to the persons who have already prepared for them. I am sure you will succee
40、d if you keep working hard. I am waiting for your good news. B: Thank you for your encouragement. I will make full use of time to struggle for success. Task 3 Free-talkT: Let us talk freely. You are allowed to move about to find a student youd like to talk with. Imagine you are going to meet a speci
41、alist about a newly-found flower. Your partner will be the assistant for the flower specialist. You both need a description of the other so you can recognize each other when you meet. Now ring the assistant to sort out the necessary information. (Of course, following the above, the students may gath
42、er around or move around to find their own favorite partners to talk with. This is a half-controlled activity. Teachers let them express whatever they want to on condition that there are some expressions on the theme. Give them about five minutes to prepare for it. Later, ask some pairs to act it ou
43、t. As usual, the teacher wont forget to give comments on what the students do, including the teachers words praising what they are doing in the first few stages. Only in this way are the students encouraged to talk freely about what they want to say and why they think so. ) Step 7 Summary and Homewo
44、rkT: In this period, we mainly focus on the speaking and listening abilities. If you feel listening or speaking poor, you had better practice more after class. Practice makes perfect. Todays homework is to describe a scientist to your partner and let your partner guess who she/he is. Then exchange.
