(The Present Perfect Passive Voice) Objectives 1.To help students build their word power by means of word formation 2.To help students understand and use the present perfect passive voice

Step 1. Learning about language In pairs do the exercises 1, 2 and 3 on page 20.

Step 2.Understanding the structure of the present perfect passive voice The structure of the present perfect passive voice is:“

have/ has ＋

been＋~ed”

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。

(1).副词的位置

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

[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。如

[误] Great changes have been taken place in China since 1978.

[正] Great changes have taken place in China since 1978. (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。例如：

All the people laughed at him.→He was laughed at by all people. (4) 双宾语动词变被动语态可将其中的一个宾语变为主语,另一个保留不动。

主动：I have given him the key. →被动：He has been given the key. 被动：The key has been given (to) him. (5) 带复合宾语的动词变被动语态时, 只能将宾语变为主语, 原来的宾补保留不动,改称主语补足语。

主动：I have asked her to help you→被动：She has been asked to help you. Step 3. Reading aloud and discovering Now go back to page 18 to read aloud and discover in the text all examples of the Present Perfect Passive Voice.
