Step 3: Grammar explanation. Teacher help the students deal with how to express the Present Perfect Passive Voice. Learn The present perfect passive voice from three parts: They are the concept(概念); The sentence patterns（句型）; The usage（用法）

I.The concept

(概念)of the present perfect passive voice 现在完成时的被动语态表示动作发生在过去, 到现在已经完成或对现在仍有影响。

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。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……”。

1. 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。

[来源学科网]2). 主语是行为动作的承受者。

II.The sentence patterns（句型）

1). 现在完成时被动语态的肯定式为：

Subject + have / has + been + done Eg. These trees ________________(water) lately. 2). 现在完成时被动语态的否定式为：

Subject + have / has + not + been + done Eg. The task _____________________(finish) yet.

3)

. 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:

Subject+ have/has +been +done

Have / has + subject + been + done ? Eg. They have been sent abroad to study English. Have they been sent abroad to study English? 4)

. 现在完成时被动语态的特殊疑问句为：

疑问词

+ have / has + subject + been + done ? Eg.

Where has the car been repaired? Who have been helped by the new computer? III.The usage（用法）

1.现在完成时的被动语态同他的主动语态一样，强调过去的动作对现在造成的影响或后果,常与already,yet, just, never, recently 等副词(常放在have或has之后)连用。

Eg.

The work has already been completed. I have never been laughted at others in public. 2. 表示一个被动的动作或状态开始于过去,持续到现在,并可能持续下去,常与for 或since引导的时间状语连用,或用于How long...?句型中。

Eg.

His car has been repaired for two days. The house has been painted since the family moved out. 3. 用在条件状语从句中，表示将来某时已经完成的动作.

Eg.

We will start as soon as the work has been finished. 注意事项

1. 只有及物动词才有被动语态,不及物动词(词组)没有被动语态。

例如: happen, take place, die, appear, disappear, fail, remain, lie, last, sit, stand, break out, come true, belong to等。

Eg.

What _____________(happen) to your brother? 2. 但许多不及物动词加介词或副词构成的动词短语，相当于及物

动词，也可以有被动语态。但动词短语是一个不可分割的整体，变为被动语态时,不可丢掉构成短语的介词或副词。

Eg.

The child ___________ (take) good care of by his grandma all these years. A notice ___________(put) up on the wall. 3. 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. How long has this book been bought?

(

) How long ago was this book bought?
