VI 教学过程：

1. 导入。

通过例句，引导学生复习虚拟语气的概念。

The doctor suggested I should stay at home. I wish I were a bird. If I had been more careful, I could have passed the exam. 虚拟语气用来表示说话人所说的话不是一个事实，而只是一种愿望、假设、怀疑或猜测等。

2.

should 虚拟的情况。

2.1学生观察例句，总结使用should引导虚拟语气的情况

1.

The teacher insisted that the students should read aloud. 2.

The policemen ordered that the people should not leave. 3.

The doctor suggested that he should drink more water. 4.

The boss required that the employers should work overtime. 总结规律：在以下动词后的从句中，用should+do虚拟，should可以省略。

一坚持

insist

二命令

order, command, 三建议

suggest, advise, propose

四要求

ask, demand, request, require

He suggested that we ____________(start) now.

(should start) 以上动词对应的名词(insistence, suggestion, advice, proposal, requirement等)后的从句中也用should虚拟。

What do you think of her advice that we ____________ (put) on a play.

(should be put)

2.2 练习：把句子补充完整。

1. He suggested that the twins ____________________ to a ballet school. (send) 2. He asked that all the photograph she took recently ______________________ in an album. (keep). 3. They insisted that ____________________________________________________________. 4. He advised that ______________________________________________________________. 5. He requested that _____________________________________________________________. (1. should be sent

2. should be kept

3.1

学生观察例句，总结规律。

1.

I wish I hadn’t argued with my parents. 2.

总结规律：

wish

过去：主+ had done

as if/ as though +

现在：主+ did/were

if only

If I had been more careful, I could have passed the exam. If I were you, I would accept the invitation. If tomorrow should be the end of the world, I would stay with my family.

学生总结规律: 1. 对过去的虚拟

If+主+had done, 主+would/could/should/might have done

2. 对现在的虚拟

If+主+did/were, 主+would/could/should/might do 3. 对将来的虚拟
