1、Period 3Listening and Speaking The General Idea of This Period This is the third period of this unit. At the beginning of this period, the teacher should (can) design some exercises to review what the students learned in the last period, that is to say, go over what the students learned about that J

2、ohn Snow defeats“ King Cholera ” . The teacher can begin with asking some questions or having a competition to make some sentences with “ John Snow” according to the passage. During this period, listening and speaking will be mainly dealt with. At the beginning, teachers focus on training the Ss lis

3、tening. This listening content is about the importance of Qian Xuesen for space travel in China, the contributions made by a botanist named Carl Linnaeus and the research into the life and work of a mathematician called Leonhard Euler. When training the Ss listening ability, teachers should start wi

4、th pre-listening, that is, lead-in. If it is necessary, teachers had better introduce some background knowledge about the listening material. Later, let the Ss listen to it. At the same time, teachers should design some simple questions. After that, the Ss have known about the listening material, an

5、d then teachers can ask them to listen to it again to be ready for more difficult questions. If necessary, the Ss can be given another time to listen. While practicing, teachers had better offer students some advice on how to do it well. Especially, train the students to predict what to be talked ab

6、out according to the hints and limited information and let them form the good listening habit of listening with the purpose of finding useful information and to summarize. Certainly, suppose there are many new words and expressions, teachers should help them to deal with them at the first place. All

7、 the listening practice should focus on developing the students listening skill. After practicing listening, the Ss are expected to learn some expressions about talking about scientific job as well as scientists achievements and recount stories. Besides those, the students are expected to learn the

8、skill of describing a person. During the course, teachers should rank class activities from the easy to the difficult. First, ask them to learn the expressions. Then, ask them to imitate it to have a dialogue. Finally, the students are expected to create a dialogue or discuss the given topic. In ord

9、er to draw students attention, the teacher had better prepare for some interesting situations. This period centers on emphasis on speaking and listening.

30、l in China. We will get to know another 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

31、 species. While Darwin wrote a book on 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 describ

32、es what this listening passage is about. 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 t

33、o study whether it is a new species. The other two statements can not convey the study. Task 2 Listening T: What you said is reasonable. Let s listen together to find whether your answer is right.

34、lowing passage. To find the name of an unknown 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

35、 _but others lay_while plants_. He used 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 th

36、e large group, for example_and one is 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-listening Let the students fill in the blankets and then check. If the students feel it difficult to do it, let them list

37、en it a third time. After checking the answers, ask the students to read it together. Step 5 Listening (Page 44) T: Look at the screen and let s read the following new words firstly. (These words are presented on the screen: analyse, pure, foundation, symbol, sin, cosin, geometry, calculus, mechanic

38、s, practical, topology) T: Can you guess which 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 Leonhar

39、d Euler. Listen to the tape and fill in the chart on the importance of Euler s work. Euler s achievementsExamples New symbols and terms Old areas of mathematics New area of mathematics Importance (After listening, ask some students to fill in it.
