The Present Perfect Passive Voice(现在完成时的被动语态) 教学内容：了解现在完成时的被动语态的结构，掌握现在完成时的被动语态的实施原则

教学目标：1.现在完成时的被动语态的结构

2.现在完成时的被动语态的主要用法

3.使用现在完成时的被动语态的注意事项

重点难点：现在完成时的被动语态在具体语境中的应用。

教学准备：教学一体机

教学过程：

Step1 Leading-in 1.

我把苹果吃了。

（把字句）

苹果被我吃了.

(被字句)

设计意图：由汉语把字句跟被字句的转化，引出被动语态这一概念。

2.Look at these Sentences from this unit and analyse: 1. Over time I have been changed quite a lot. 2. First as a PC (personal computer) and then as a laptop, I have been used in offices and homes since the 1970s. 3. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told!

4. Since the 1970s many new applications have been found for me. 5. I have also been put into robots and used to make mobile phones as well as help with medical operations. 6. I have even been put into space rockets and sent to explore the Moon and Mars.

观察可知：这几句的主语I全部为________（人/物）,他们与动词的关系为_______(主动/被动)关系。

设计意图：根据学生观察以及分析句子，引导学生分析现在完成时的被动语态的构成形式和用法。

Step2 Grammar learning

总结：现在完成时的被动语态

1.结构：_______________________________- 2.用法：现在完成时的被动语态同它的主动语态一样，强调过去的动作对现在造成的影响或结果，但主语为动作的承受者，表示“……已经被……”。

The new school has been set up. 新学校已经建成了。

3.

现在完成时被动语态的肯定式为：_____________________________ The experiment has been done successfully. 这个实验做得很成功。

现在完成时被动语态的否定式为：_________________________________ Tom’s novel has not been published. 汤姆的小说还没有被出版。

4.

现在完成时被动语态的一般疑问句____________________________ Has his bike been repaired? 他的自行车修好了吗？

5.现在完成时被动语态的特殊疑问句为：____________________________ Who has been invited? 谁受到了邀请？

注意: 1. 副词的位置

often, usually, always, never, hardly, seldom等副词置于have / has和been中间。

如：Such a man has hardly been believed. 2.

并不是所有动词都有被动语态

happen, take place, break out, belong to, cost, last等不及物动词或词组无被动语态。

如：Great changes have taken place in China since 1978. 3. 短语动词不可分割也不可省略其中的介词或副词。

The patients have been taken good care of.

设计意图：通过例句以及上单元语法一般将来时的被动语态，让学生独立总结现在完成时的被动语态的结构，用法，否定句，疑问句形式。
