新授课

一．被动语态(passive voice)是动词的一种形式，用以说明主语与谓语动词之间的关系。英语的语态共有两种：主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。只有及物动词才有被动语态。被动语态是动词的一种特殊形式，一般来说，只有需要动作对象的及物动词才有被动语态。汉语往往用"被"、"受"、"给"等被动词来表示被动意义。被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只改变be的形式，过去分词部分不变。疑问式和否定式的变化也如此。

1.A new computer was bought to me by my father yesterday.

2.The children are looked after very well by Mrs Zhang.

3.He was seen to come into the meeting-room.(这里注意一下：由于see是感官动词，所以改为被动语态后要加to)

4.English is found very useful by us.

5.A lot of trees are planted by him.

后面的“by…”可加可不加，只要句子表示的是被动的意思就可以了。

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

二、形式

现在完成时的被动语态的肯定式为：have/ has +been +done。如：

The experiment has been done successfully. 这个实验做得很成功。

现在完成时的被动语态的否定式为：have/ has +not +been +done。如：

Tom’s novel has not been published. 汤姆的小说还没有被出版。

现在完成时的被动语态的一般疑问句需将have /has提到主语的前面。如：

Has his bike been repaired? 他的自行车修好了吗? 现在完成时的被动语态的特殊疑问句为：疑问词+have /has +been +done? 如：

Who has been invited? 谁受到了邀请? 三、注意

在使用现在完成时的被动语态时要注意以下四点：

1.过去分词前的助动词的形式是have /has +been，不可漏掉其中的任何一个。

【误】Many new buildings been built since 1980. 【正】Many new buildings have been built since 1980. 【析】谓语部分结构不全，时态部分不完整。

2.必须表示被动。如：

【误】Something bad has been happened to him. 【正】Something bad has happened to him. 【析】被动语态误用。happen为不及物动词，不及物动词没有被动语态。

【误】The door has been opened of itself. 【正】The door has opened of itself. 【析】有些动词如open，break，drop等既可以作及物动词，又可以作不及物动词，若不强调谁是动作的发出者，我们通常用主动语态。of itself意思是“自动地”，因此，此句不可用被动语态。

【误】I have introduced to Mr. Smith. 【正】I have been introduced to Mr. Smith (by Mr. Wang). 【析】introduce为及物动词，I是introduce动作的承受者，应用被动语态。

3.由finish，buy, start, begin，post，return，borrow, join，marry，open等短暂性动词构成的现在完成时的被动语态不能与表示一段时间的状语如.for four days，for a long time等连用，如需表达这样的意思，可改变动词或时态。如：

【译】：这本书买了多久了?

【误】：How long has this book been bought? 【正】：How long ago was this book bought? 但这类动词的否定式可与since或for引导的表示一段时间的状语连用。如：

No books have been bought since last week. 自上周以来，没有人来买过书。

检测巩固

一．现在完成时主动语态四种基本形式

1.肯定式：

___________________________________

2.否定式：

____________________________________

3.一般疑问式：___________________________________

4.特殊疑问式：特殊疑问词＋has/have＋主+done

二．现在完成时被动语态四种基本形式

1.肯定式:__________________________________________

2.否定式：_________________________________________

3.一般疑问式：______________________________________

4.特殊疑问式：特殊疑问词＋has/have +主＋been done

思考：在现在完成时主动与被动语态四种基本形式中，被动语态谓语与主动语态谓语的不同主要表现在哪里？

三．规则动词变过去分词

1.Ｖ+ ed

listen----→____________

2. e + d like -----→____________

3. 辅+y---→i +ed study---→_____________

4. 双写+ed

stop----→_____________

1. The experiment ___________________(do) successfully.

2. Has his bike_____________________(repair)?

3. How many new words__________________(learn) by the students?

Test 2(单句语法改错)

1. A personal computer has bought by us.

2. The computer was used every day since we bought it.

3. Tom’s novel has been not published.

Test 3(主动变被动)

1.She has borrowed my books.→

2. He has developed a kind of intelligent robot.→

3.They have not solved the problem yet.→

总结升华

方法步骤：

１.原句划成分

２.原宾变现主

３.原谓变被动

４.原主变介宾

５.其余都不变

板书设计: 1.现在完成时被动语态的结构

2.肯定句：have/has been done 3.否定句: have/has not been done 4.疑问句：have/has+主语+been done 特殊疑问句：特殊疑问词+have/has+主语+been done 主动句：1.

The shop has repaired my computer very quickly 被动句：2.My computer has been repaired by the shop very quickly.

3.We have made a plan.----→A plan has been made by us.

4.My friend has bought a new personal computer.
