Period 3Listening and SpeakingThe General Idea of This PeriodThis 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 John 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 listening. 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 with 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, and 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 about 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 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 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 order to draw students attention, the teacher had better prepare for some interesting situations. This period centers on emphasis on speaking and listening. The teacher should try his or her best to encourage the students to say something. Dont always correct the mistakes that the students would make while speaking. Otherwise, the students would feel reluctant to speak out their opinions. Teaching Important PointsTrain the students speaking ability by describing, talking and discussing.
