教材分析
this is the third 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 them some revision exercises. then lead in the new lesson.
this teaching period mainly deals with the following: 1. reviewing noun clauses as the object and as the predicative; 2. learning the new grammar items: noun clauses as the subject. students often feel noun clauses abstract and difficult to learn, so it is necessary to make the lesson interesting and lively, and connect it with their daily life in order to let it easy to accept and understand. firstly, the teacher can ask students to read the passage how life began on the earth again, tick out all the sentences from the passage where noun clauses are used as the subject, and then translate them into chinese. secondly, compare and discover the uses of each noun clause by giving a lot of example sentences. thirdly, do the exercises in discovering useful structures on page 29 and more exercises for students to master the related noun clauses. finally, summarize the use of noun clauses as the subject and let students make it clear how each noun clause is being used in the situations.
at the end of the class, ask students to do the exercises in using structures on page 64 and more additional exercises for consolidation.
