教 材 分 析

This teaching period mainly deals with the grammar: the subjunctive mood (2). From Uhit1 we have already known that in English language, verbs are often divided into three different moods---the indicative mood, the imperative mood and subjunctive mood, we have learned two kinds of subjunctive mood in Unit1: one is used in the subjunctive adverbial clause
of condition , the other is used in the object clause of wish. In this period we will continue to focus on some special sentence patterns of subjunctive mood.
