According to the contents based on the new course standard,senior students are required to understand the function of grammar and can use it freely.Gradually contact and understand complex language phenomena so that students may have the ability to summarize、analyze and explain.This is the third period of this unit.In this period,we mainly deal with the changes between Direct Speech and Indirect Speech.In order to make students grasp it well,I think it is necessary to give them more practice and encourage them to find out the problems of grammar by themselves.
