16、e present future passive voice?(看你所挑句子的时态，然后思考一般将来时被动语态的结构) 4 总结 summing upThe structure of the present future passive voice is (现在完成时被动语态的结构)： _Step III 巩固练习 The present perfect passive voice 现在完成时的被动语态 1现在完成时被动语态的构成 (1) 现在完成时被动语态:has/have + been + 及物动词的过去分词否定式是:在havehas + not been + 及物动词的过去分词 疑问句式

17、: have / has + 主语 + been + 及物动词的过去分词特殊疑问句式：疑问词+havehas + 主语 + been + 及物动词的过去分词 比如：The 29th Olympic Games havent been held yet 第29届奥运会还没有举行。 Has his new novel been translated into English yet? 他的新小说被译成英语了吗?How long has the book been kept? 这本书借了多长时间了7 How many new words have been learned this term? 这学

18、期已经学了多少新单词了? 2现在完成时被动语态的主要用法 (1)表示一个被动的动作发生在说话之前，强调对现在的影响或结果。 The book has been translated into English 这本书已经被翻译成英文了。(2)表示被动的动作开始于过去，持续到现在，并有可能持续下去，常与for或since引导的时间状语连用，或用于How long?句型中。表示从过去延续到现在并包含现在在内的一段时间状语有：already, yet, lately, recently, in the last/past few years, since then, up to now, so far

19、 等。 How long has the computer been used? 这台微机用了多长时间了?【注意】(1)现在完成时被动语态的两个助动词：havehas和been缺一不可。(2)注意与一般过去时被动语态的区别。一般过去时被动语态表示一个被动的动作发生在过去，其结果对现在没有影响；而现在完成时被动语态的动作或状态尽管发生在过去，但侧重说明该动作或状态对现在造成的影响或结果 The machine has been repaired机器已经修好了。(说明动作发生在过去，对现在有影响，修好了。) The machine was repaired yesterday机器昨天修了。(只说明

20、动作发生在昨天。)(3)不可与确定的表示过去或将来的时间状语连用(如yesterday，three days ago，in l970等)，但可与不确定的时间状语连用(如already，yet，just，often，recently，in the past few years等)。 They have been punished recently 他们近来受到了惩罚。(4)有些动词像finish，buy，start，begin，return，join，marry，open，die等，表示的动作很短暂，称之为短暂性动词或非延续性动词。它们构成的现在完成时被动语态不能与for构成的短语，since构

21、成的短语或引导的句子连用，也不能用于How long?句型中。 The book has been finished for two years()The book was finished two years a90()(5)动词短语是一个不可分割的整体，在被动语态中要保持其完整性，其中的介词或副词不可省略。 The orphans have been taken good care of here 孤儿们在这里受到很好的照顾。使用现在完成时被动语态要注意以下几点：1. 只带有一个宾语的动词变为被动语态时，将主动语态的宾语变为被动语态的主语。例如：We have built many hou

22、ses in the past ten years.Many houses have been built in the past ten years.2. 带有双宾语的动词，如give, send, bring, take, teach, show, tell, make, sing, write, read, sell, buy, tell, pay, lend, pass, promise等，变为被动语态时，可将其中一个宾语变为主语，另一个保留不动。例如：We have given him the book.He has been given the book.The book has

23、been given to him.3. 带有复合宾语的动词变为被动语态时，只能将宾语变为主语，原来的宾补改为主语补足语。原来省略to的不定式作宾补的，被动语态中要用带to的不定式。例如：I have told them to help you.They have been told to help you.I have made her work hard.She has been made to work hard.4. 短语动词变为被动语态时，要注意保持短语的完整性，动词后原有的介词或副词不可遗漏。例如：They have referred to the books.The books

24、have been referred to (by them). He has thought of a way of dong it.A way of doing it has been thought of. 典例解析1.Hundreds of jobs _ if the factory closes. A. lose B. will be lost C. are lost D. will lose解析本句的意思是：如果工厂倒闭，那么将失去数百个工作岗位。lose a job意为”失业”。工作将被失去，要用将来时态的被动语态，因此排除答案A、C和D，答案选B。2.The mayor of

25、Beijing says that all construction work for the Beijing Olympics _ by 2006. (2004北京)A. has been completed B. has completed C. will have been completed D. will have completed解析宾语从句中主语all construction work for the Beijing Olympics和谓语动词complete之间有被动关系，所以谓语要用被动语态，因此排除选项B和D；by 2006暗示谓语要用将来完成时态，因此答案选C。3.

26、All the preparations for the task _, and we are ready to start.(NMET2000春招)A. completed B. complete C. had been completed D. have been completed解析本句的意思是：这项工作的一切准备工作已经就绪,我们只等开始了。前半句主语和谓语有被动关系，后半句暗示说话是从现在着眼,所以用现在完成时态的被动语态。答案D。Step4拓展延伸单项填空1一The student _home because of stealing - Im so sorry to hear t
