T：Boys and girls，now please pay attention to the following sentence Eg : We have finished our homework.

T: What verb tense is used in this sentence?

Yes，present perfect tense is used in this sentence. T: Do you know what is the present perfect tense? 定义：现在完成时表示动作发生在过去, 到现在已经完成或对现在仍有影响。

T: Well done. Can you tell us the structure of the present perfect tense? Quite right. The structure of the present perfect tense is “subject＋have/has done＋object”. Step 2: Teaching Grammar 1.Leading-in

T: And what verb voice is used in this sentence? Good job. It is used the active voice. T:Do you know the difference between an active voice and a passive voice?

主动语态即主语为动作的执行者；被动语态即主语为动作的承受者。

2.Explaination

T:1.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……”。

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

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

3.现在完成时被动语态的否定式为：have / has + not + been + done Eg: 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需将have / has提到主语的前面。

Eg:

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：疑问词

+ have / has + been + done Eg: Who has been invited? 谁受到了邀请？

现在完成时的被动语态表达以下两个概念：

1. 说话时已经完成的动作或出现的结果。

2. 主语是行为动作的承受者。

Eg: I have been told about it many times．

The bridge has just been built．

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。

Eg:[误] Such a man has been hardly believed. [正] Such a man has hardly been believed. 2. 并不是所有动词都有被动语态

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

Eg:[误] Great changes have been taken place in China since 1978. [正] Great changes have taken place in China since 1978. 2) open, break, drop等不强调动作发出者时常用主动语态。

Eg:[误] The door has been opened of itself. [正] The door has opened of itself. 3. 短语动词不可分割或省略其中的介词或副词。

Eg: The SARS patients have been taken good care of. 4. 一些特殊动词, 如borrow, finish, begin, buy, start, return, marry, open, join等

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连用。若要表达

相应的意思, 则需改换动词或时态。

Eg:My brother has had(不能用has bought) this bike for almost four years. [误]How long has this book been bought?

[正]How long ago was this book bought? 主动语态变被动语态的方法

1) 把主动语态的宾语变为被动语态的主语。

2) 把谓语变成被动结构(be＋过去分词)(根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式)。

3) 把主动语态中的主语放在介词by之后作宾语, 将主格改为宾格。

Eg: 1.All the people laughed at him.

→ He was laughed at by all the people.

2.They make the bikes in the factory.

→ The bikes are made by them in the factory.

口诀: 宾变主, 主变宾, by短语后面跟。

谓语动词变被动, be后“过分”来使用。

4）有双宾语的句子变成被动语态有两种情况

①间接宾语(人)变成被动语态的主语，直接宾语(物)仍保留在原位。

②直接宾语(物)变成被动语态的主语，在间接宾语(人)前加介词to或for(make，buy，cook等用for)。

Eg：He gave me a pen yesterday. → I was given a pen(by him) yesterday.

→ A pen was given to me(by him) yesterday.

Step 3:Consolidation exercise: 1.高考链接。

2.用动词正确形式填空。

3.用被动语态改写下列句子。

Homework: Try to remember the grammar rules and do exercises 1, 2 and 3 on page 21.
