教学内容分析
This teaching period mainly deals with the grammar：the subjunctive mood(2)．From Unit 1 we have already known that in the English language，verbs are often divided into three different moods—the indicative mood，the imperative mood and the subjunctive mood.We have learned two kinds of subjunctive mood in Unit 1：one is found after the word “wish”，the other is found in a clause beginning with the word “if” talking about the imagined consequence of a situation at present that is impossible to happen.In this period we will continue to focus on another kind of subjunctive mood，that is，the subjunctive mood beginning with the word “if”，talking about the imagined consequence of a situation in the past that did not happen or in the future that is not likely to happen.
