M6Unit4 Review and consolidation of subjunctive mood

Learning objectives: 1. Form a basic knowledge structure of subjunctive mood 2. Master the basic skills to solve multiple choices about subjunctive mood 3. Use subjunctive mood properly in your composition

Teaching importance and difficulties 1. Guide students to form a knowledge structure of subjunctive mood 2. Express their ideas with subjunctive mood

Teaching procedures: Step1: 课前检测反馈及错因归纳: 真假不辨; 类别不清;时间混淆;主从不分

Step2: Discussion and presentation 1. 什么是虚拟语气？（望名生义）

2. 如何通过谓语动词的时态来表现“虚拟”？（一个原则）

3. 虚拟条件句中从句和主句谓语动词虚拟形式有何差别？（两种形式）

4. 虚拟语气可归结为哪几类？（三种类型）

5. 虚拟语气选择题的解题步骤有哪几步？（四个步骤）

Step3: 厘清概念

“虚”相对于“实”，用于表述与事实相反或可能性很小的情况；“拟”即“打比方”或“作比喻”：发话人想传递这样一个信息：“这只是一个假设”。例如：

If I died tomorrow, Vs. If I die tomorrow, 引申用法举例：Lend me some money! Can you lend me some money? Could you lend me some money? Step4: 搞懂一个原则

改正以下句子的语法错误：

If I am you, I will kill him! If I saw him yesterday, I would kill him yesterday. I will kill him tomorrow, but I don’t have the courage.

原则：移（或者倒退）：现在变过去，过去变过去完成，将来变过去将来！

Step5: 分清两种形式

在虚拟条件句中要分清主从句，因为两者要采用不同的表现形式：

if从句中遵循时态前移的基本原则（（过去 had done, 现在 did, 将来 did/should do/were to do）

主句中必须使某个用情态动词的过去式: would/could/might/should 例句：If you had worked harder, you could/would/might have passed the exam. 总结：主句中的情态动词主要是因为语意需要。

Step6: 识别三种类型：从谓语动词的虚拟表现形式角度，可大致归为三类：

1. 命令、建议（注意委婉建议句型）、要求：(should) do 其中：It is (high) time that sb. should do/did sth. 2. 愿望、比喻等（wish、would rather、if only、as if）

其中：would rather that sb. had done/did sth.

3. 虚拟条件句：if从句(可隐藏）+主句（应用表格）

注意：混合时间、从句倒装、从句隐身。

三大类各有一个特例，背熟一个简化口诀：“if将来有三变，It’s time 用过去，would rather 没将来！”

Step7: 牢记四个步骤

1. 判虚实(二选一）2. 归类别（三选一）3. 定时间（三选一）4. 分主从（二选一）

Step8: 分析5道错题

分，满分10分）

（1）近期我校认为有必要( think it necessary that)规范（regulate）学生的课堂行为（classroom behavior)。（2）其中一项要求(requirement)是学生课桌上最多摆放三本书。部分学生赞成此项规定，（3）他们认为假如 (if) 自己坐在一大摞（a big pile of）书后面，会觉得即使(even if)自己没有听讲，老师也不会发现。（4）甚至有学生认为如果(if)早点有这么一条规定的话，自己现在的成绩可能会好多了。（5）但部分学生宁愿(would rather)学校不要过多干涉(interfere with)他们的自由。（6）他们坚持要求（insist）学校要给学生足够的信任，（7）不要把他们当作(treat sb. as if)小孩子来对待。

对此，你对学校有什么建议？假如你是校长，你会怎么做？
