Using LanguageⅡ第二课时教学实录

Unit 3 Computers Learning about language Teaching Introduction This is the fourth teaching period of this unit. To test whether students have grasped the important and difficult language points they learned in the last period, the teacher should first offer some revision exercises. The Pattern “And my memory become so

large that I couldn’t believe it.” is a bit important, so special exercise should be designed. This teaching period mainly deals with the grammar: the present perfect passive voice. Firstly, the teacher can ask students to read the reading passage again, tick out the sentences in the present perfect passive voice from the reading passage and translate them into Chinese. Secondly, compare and discover the structure and usages of the present perfect passive voice by giving a lot of example sentences. Thirdly, do the exercises in Discovering useful structures on page 21 and more exercises for students to master the present perfect passive voice. Finally, summarize the present perfect passive voice. Teaching goals: ⅰ Knowledge goals

Discovering Ask students to look at the screen and tell which sentence is active voice and which is passive voice. 1.The old man has been dead for two years. 2.They have done the job. 3.The house has been built for 3 years. 3．Thinking Let students look at the tense used in the sentences they picked out and think over this question: What is the structure of the present perfect passive voice? 4.Summing up The structure of the present perfect passive voice is “have/has+ been + p.p.”. It is a combination of the present perfect tense (have/has + done) and the passive voice (be + p.p.).
