教材分析
This is the last teaching period of this unit, so the emphasis should be placed on going over and summarizing what has been learned in this unit. It includes the following parts: Summing up, Learning tip, and assessment and consolidation exercises.
Summing up summarizes the whole contents of this unit from the aspects of topics, vocabulary and grammar. The teacher can first use this part to let students sum up what they have learned and then explain what students couldn’t understand very well in this unit. An experienced teacher should design some additional exercises for students to do in order that they can learn to use and grasp all the contents.
