Step1 Lead in

Let’s retell the passage FRANKEINSTEIN’S MONSTER that we have learnt in our last lesson.

1. I wish I had not created this creature.

2. I wish I was not here. 3. I wish I could disappear.

4. I wish I had not done this terrible thing. 5. I wish I was dead. According to these sentences, please answer: What’s mood? What’s Subjunctive Mood? Step2

语气是动词的一种形式，表示说话人对某一行为或事情的看法和态度．英语句子中谓语动词的语气有三种：

1. 直陈语气（The Indicative Mood）直陈语气用于直截了当地陈述事实、描述状态：

He has published quite a number of essays this year .他今年已发表了好几篇论文。

2. 祈使语气（The Imperative Mood）

祈使语气用于提出请求、命令、建议或是劝告等：

Wait outside until you are asked . 请在外面等候，请你进再进去。

Let's just take a break, shall we ? 我们休息一会Show some sentences on the blackboard.

Answer the two questions

导入新课，进入本节课主题：虚拟语气

明白什么是语气以及什么是虚拟语气

儿，好吗？

3. 虚拟语气（The Subjunctive Mood）

虚拟语气用于表示主观愿望和假设的虚拟情况。虚拟语气不太顾及事实的存在，它表现出说话人的主观因素比较多。所以说话人所讲的内容往往是与事实相反的；或是其实现的可能性微乎其微，甚至于没有实现的可能性。当然，有时为了使说话的语气客气、缓和、委婉，也使用虚拟语气。例如：

I wish you were more careful .但愿你更细心一些。

If I had more money, I would buy a bigger apartment. 我要是有再多一点钱，我就买一套更大一些房子。

Would you mind shutting the door ? 劳驾您把门关上。

2) If you had arrived at train station 10 minutes earlier, you would have caught the train.

3) If you should fail in the exam, you should wait for it again next year. Step6 Make sentences with subjunctive mood

Step7注意

1. 省略if 的条件句

使用虚拟语气时，有时候可以省略引导条件状语从句的连词if。这时，从句部分要使用部分倒装，即将从句部分的助动词were / had / should等提到主语前面。

练习：

1) Were I you, I would not tell him that.

2) Should it snow tomorrow, many crops would die of cold.

3) Had you listened to the teacher carefully yesterday, you would know how to do the exercise now. 2.有时候，条件和结果不是指同一个时间，

Show the exercise on the screen

Show the notice on the screen and ask students to finish exercise by themselves

Finish the exercise

Make sentences in groups

study the notice by oneself and finish the

exercise

及时掌握学生的学习情况

把所学知识运用到实际当中来

体现自主学习

这时，应根据上面谈到的几种情况，使用相应的形式，这种虚拟语气形式被称为错综虚拟语气。

如：

If you had listened to the teacher carefully yesterday, you would know how to do the exercise now. 如果你昨天认真听了老师的讲话，你现在就知道如何做这道题了。

练习：如果他听了我的建议，他就不会陷入麻烦了．

If he had taken my advice, he would not be in trouble. 3.含蓄性条件句

在表示假设的虚拟语气中，有时假设的条件并不以条件从句的形式出现，而是通过上下文或句中内在的逻辑关系，或用其它形式表达出来，这就是“含蓄条件句”。

如：Without air (= If there were no air) , there would be no living things.

如果没有空气，就不会有生物。

With his help (= If I had her help), I would do the experiment well.

如果有他的帮助，我会做好这个实验。
