学习必备欢迎下载一构成: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 donehave/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洁净的,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显现的结果,强调对现在 ;The door has been locked. 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 , 连续到现在 , 并可能连续下去,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.有人告知他这事很多次了;(可能仍会有人告知他)4). 用在中, 表示将来某时已完成的动作;如: We ll start as soon as the work has been finished. 工作一完成我们就立刻动身;四使用现在完成时被动语态留意事项:1). 副词的位置often, usually, always, never, hardly, 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). 并不是全部动词都有被动语态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). 但很多不及物动词加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行分割的整体,变为被动语态时,不行丢掉构成短语的 ;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;但如直接将 变为主语,就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.被动has been givenby his parents recently.被动has been givenby 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,而原先的宾语补足语就变为相应的 ;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,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 hasn t been finish他ed的. 家庭作业仍没有写完;Has this bridge been finished. 这座桥竣工了吗?The blackboard has been cleaned, hasn黑板已经t擦it.过了,是吗?六、现在完成时被动语态例题讲解 例 1 Paper moneyfor over a thousand years.A. used B. has been usedC. 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间段,依据题意,谓语动词所要表示动作可能仍要连续下去,符合现在完成时,所以应当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 italready.A. has taken B. tookC. 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;所以应当用现在完成时的被动式;答案是D ;学习必备欢迎下载 例 3 the letterto Mr Black. No. Its still on the desk.A. Has; given B. Will; be given C. Was; givenD. Has; been given 析 此题是一道问答情形题;问话人想知道的是动作的结果,所以应当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 longat 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 引导的是一个特别疑问句,从how long 和 since 1990 我们可以确定应当是现在完成时,再从意义上看,应当使用被动语态,所以答案应当是B; 例 5 The reason for all the changes being madeto us yet.A. as not explained B. has not been explainedC. 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:仍没有给我们说明作出变化的理由;应当是现在完成时的被动式的否定式;答案是B; 例 6 Great changesin my hometown and a lot of factories.A. have been taken place; are being set upB. have taken place;have been set upC. are taken place; had been set upD. 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;依据题干上下文可以看出,都应当是现在完成时,所以答案是B ;强化练习题I单项挑选1.
