Grammar and usage(1): Unreal conditionsppt配套的教案及板书设计

虚拟语气（1）的教学设计

宁远二中

潘慧敏

教学目标和内容：

1. 能识别真实条件句和非真实条件句；

2. 掌握非真实条件句中的三种时态的不同结构以及在语言环境中的运用；

3. 掌握当if从句中含有should, were, had时if的省略及引起的部分倒装。

教学步骤：

一．观察认识：Observe the following sentences and tell whether they are real or unreal conditionals.（学生朗读）

1. If you study hard, you will make great progress.

2. If I were a bird, I would fly high in the sky.

3. If you come to Yongzhou tomorrow, I will go to meet you at the railway station.

4. I won’t fly to Hongkong tomorrow. If I should fly to Hongkong, I would call on you.

5. — What a pity! You failed the English test.

—

I can’t agree more. If I had studied harder, I could have passed the test.

结论：

条件句分为两种, 一种是真实条件句, 一种是非真实条件句, 只有在非真实条件句中才用虚拟语气, 在真实条件句中, 要用陈述语气。

（环节设计目的：本环节是通过学生的自主观察，发现问题并产生疑问，感受真实条件句和非真实条件句的不同。）

二．自主学习（学生先自己做，再讨论）

讨论并判断下列非真实条件句是与现在、过去还是将来事实相反：

1. — Have you visited Brunei?

— No.

— If you came to Brunei, you would have to take off your shoes before going into someone’s house.

2. If I had time tomorrow, I would certainly help you.

3. If you had joined the chat room ten minutes ago, you would have known what we were talking about! 4. If the man had pointed with his first finger when he was in Brunei, everyone would have thought that he was very rude. 5. If I had this chance, I might want to be a business consultant.

6. If I had one million yuan, I would donate it to the Red-cross Center.

归纳列表：(学生填表) 时间

与现在事实相反

从句

If +主语+动词的过去式(be-were)…

If+主语+had +过去分词

If+主语+动词过去式；

If+主语+were to+ 动词原形; If+主语+should + 动词原形;

主句

与过去事实相反

与将来事实相反

补充：

1. 在if I /he/she/it 之后, 可用were代替was。两者在意义上没有区别, 但是were更为正式, 特别是在称述心存怀疑的事情时:

If she were ready, we would go. 2. 在与将来事实相反的条件从句中,我们可以用were to或should +do来表示,如:

If I were to fail my English test, I would have to take it again at the end of the term.

If he should come tomorrow, I would talk to him about it. （环节设计目的：本环节是通过学生的自主学习，讨论，合作探究等活动分析解决问题。并在已经形成的认知上形成初步结论。）

三：虚拟条件句中的省略与倒装

（教师补充）

在非真实条件句中,如果有were, had, should, 我们可以将if省略,把这些词置于首,采用部分倒装的形式。

即学即练：

请你把下列划线部分所在的if从句改为倒装句：

1. If I should meet her, I would tell her.

= ________________________, I would tell her.

2. If I were in your position, I would do it better.

= ____________________, I would do it better.

3. If they had made preparations, they would have succeeded.

=___________________________, they would have succeeded。

（环节设计目的：虚拟条件句中的省略与倒装是高考常考形式，特别单列指出引起学生重视并给于练习巩固。）

四．【巩固练习】

一、请同学们做教材第40页的练习题：

Ye Fei asks Ma Li for help on his homework. Fill in each blank with the correct form of the verb in brackets. 核对答案：

二、请同学们做教材第41页的练习题：
