Then lead in the new lesson.This teaching period mainly deals with the following: 1. Reviewing noun clauses as the subject; 2. Learning the new grammar item: noun clauses as the appositive.

Thirdly, do the exercises in Discovering useful structures on Page 37 and more exercises for students to master the related noun clauses.
