1、精选优质文档-倾情为你奉上一构成：现在完成时被动语态的结构就是: 现在完成时态和被动语态结构的叠合. 主动语态 被动语态现在完成时 have/has done have/has been done试比较以下几组句子的谓语结构：1) 主动句：He has repaired the machine for two hours. （他修理这台机器已有两小时了） 被动句：_.（这台机器已修了两小时了） 2). 主动句：The teacher has borrowed the books. （老师把那些书借走了） 被动句：_. （那些书被老师借走了）二现在完成时被动语态的概念现在完成时被动语态强调一个发

2、生在过去的被动性动作对现在造成的影响，它有两层意思：1) 动作_，强调对现在造成的影响或结果：2）主语与谓语动词之间为_。如：Our classroom has been cleaned, you neednt clean it now.析:该句强调教室已被打扫，对现在造成的影响是教室是干净的，强调这个影响，你就没必要再打扫了。三、现在完成时被动语态的主要用法1). 主语是行为动作的_。如： The Temple of Zhang Fei has been rebuilt. 张飞庙已经过重建。2). 说话时已经完成的动作或出现的结果，强调对现在_。The door has been locke

3、d. 门已经被锁上了。（结果是现在没人能够进去）3). 动作或状态始于过去, 持续到现在, 并可能持续下去，常与_引导的时间状语连用，或用于“_”句型中。如： He has been told about it for many times. 有人告诉他这事很多次了。（可能还会有人告诉他）4). 用在_中, 表示将来某时已完成的动作。如： Well start as soon as the work has been finished. 工作一完成我们就立即动身。四使用现在完成时被动语态注意事项:1). 副词的位置 often, usually, always, never, hardly,

4、seldom等副词置于_和_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 happen, take place, break out, belong to, cost, last等_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)但许多不及物动词加

5、介词或副词构成的短语动词，相当于及物 动词，也可以有被动语态。但短语动词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_。如：eg 1) The child has been taken good care of by Grandma Wang all these years.2）A notice has been put up on the wall.4.1）双宾语的动词变为被动语态时，常将_变为主语；但若直接将_变为主语，则需要在间接宾语前加上适当的_（to 或for）。 eg （1）His parents have given him a new bike recently.

6、被动_ has been given _ (by his parents) recently. 被动_ has been given_ (by his parents) recently.4.2）带有复合宾语的动词在变为被动式时，只能够把_变为主语，而原来的宾语补足语则变为相应的_。eg （2）I have asked him to post the letter. 被动_五、现在完成时被动语态的否定式和疑问式。 从现在完成时被动语态结构has/ have been done可以看出_为助动词，因此现在完成时被动语态的各种句型变换均应借助于_来完成。构成否定句时直接在has/have后面加_，

7、构成一般疑问句时将_提前，构成反意疑问句时，附加问句借助_。如：His homework hasnt been finished. 他的家庭作业还没有写完。Has this bridge been finished? 这座桥竣工了吗？The blackboard has been cleaned, hasnt it? 黑板已经擦过了，是吗？六、现在完成时被动语态例题讲解例1 Paper money_for over a thousand years. A. used B. has been used C. has used D. is using 析 主语和谓语是被动关系，而且时间状语是一个时

8、间段，根据题意，谓语动词所要表示动作可能还要继续下去，符合现在完成时，所以应该是现在完成时的被动式。答案是B。例2 We want to sit at the table near the window. Im sorry，but it_already. A. has taken B. took C. was taken D. has been taken 析 从题干中的答语知道，座位已经有人坐了，说明结果。所以应该用现在完成时的被动式。答案是D。例3 _the letter_to Mr Black?No. Its still on the desk.A. Has; given B. Will

9、; be given C. Was; given D. Has; been given析 此题是一道问答情景题。问话人想知道的是动作的结果，所以应该是现在完成时的被动式。其疑问式是把这一结构中的助动词have或has提前，所以正确答案为是D。例4 How long_at this job? Since 1990.A. were you employed B. have you been employedC. had you been employed D. will you be employed析 how long 引导的是一个特殊疑问句，从how long和 since 1990我们可以确

10、定应该是现在完成时，再从意义上看，应该使用被动语态，所以答案应该是B。例5 The reason for all the changes being made_to us yet.A. as not explained B. has not been explained C. didnt explain D. were not explained析 the reason 是主语中心词，它和谓语explain之间是被动关系；题干的意思是：还没有给我们解释作出变化的理由。应该是现在完成时的被动式的否定式。答案是B。例6 Great changes_in my hometown and a lot

11、of factories_. A. have been taken place；are being set up B. have taken place；have been set up C. are taken place；had been set up D. had taken place；will be set up析 take place 是不及物动词词组，因此没有被动语态；而factories和set up之间是被动关系；根据题干上下文可以看出，都应该是现在完成时，所以答案是B。强化练习题I 单项选择1.
