从容说课
this is the third teaching period of this unit. to test whether the students have grasped the important and difficult language points they learned in the last period, the teacher should first offer them some revision exercises. the pattern “not all. . . ”or “all. . . not. . . ” is a bit important, so special exercises should be designed.
this teaching period mainly deals with the grammar:the attributive clause introduced by that, which, who and whose. firstly, the teacher can ask the students to read the text a night the earth didn’t sleep, tick out the attributive clauses in the reading passage and translate them into chinese. secondly, summarize the usages of the attributive clause, especially the usages of relative pronouns:which, that, who, whom and whose by giving a lot of example sentences. thirdly, do the exercises in discovering useful structures on page 28 and more exercises for students to master the usages of which, that, who, whom and whose.
at the end of the class, ask the students to read the passage a safe home and do the exercises in using structures on page 64 and additional exercises for consolidation.
