现在完成进行时的被动语态

现在完成时态被动语态的构成：1、肯定式：have/has+been+done。如：The experiment has been done successfully.这个实验做得很成功。2、否定式：have/has+not+been+done。如：Tom"s novel has not been published.汤姆的小说还没有被出版。3、一般疑问句需将have/has提到主语的前面。如：Have the letters been posted?信已经寄出去了吗？Yes, they have.是的，已寄出了。Has his bike been repaired?他的自行车修好了吗？No, it hasn"t.不，还没有被修好。4、特殊疑问句为：疑问词＋have/has+been+done。如：How long have the machine been repaired？这些机器已被修好多长时间了？现在完成时态被动语态的用法1、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，通常与already，yet，just，never，recently等副词连用。如：The room has already been cleaned.房间已经被清扫干净了。（含现在已不用清扫房间了）The doctor hasn"t been sent for yet.还没有派人去请医生。（含现在应派人去请医生）The office looks nice. It has just been cleaned.办公室看起来很干净。它刚被打扫过。（含现在已不用清扫房间了）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等引导的时间状语连用，或用与How long…？的句型中。如：The machine has been repaired for two hours.这台机器已修了两小时了。How long has the project been carried out?这项工程已被实施多长时间了？

现在完成时的被动语态其结构为“haveorhas+been+done”，过去完成时的被动语态是过去完成时态和被动语态的叠合。表示过去某一时间以前已经完成的动作，常与by，before等引导的时间状语连用。由“had+been+过去分词”构成。过去完成时态的被动语态的构成：1）过去完成时的被动语态的肯定式为：had + been + done。2）过去完成时的被动语态的否定式为：have / has + not + been + done。3）过去完成时的被动语态的一般疑问句需将had提到主语的前面。4）过去完成时的被动语态的特殊疑问句为：疑问词 + had+ been + done。

现在完成进行时是没有被动语态的，如果有现在完成进行时的主动结构的句子变为被动结构，可以用现在完成时。现在完成时被动语态结构为has/have been done，使用has been done时主语为单数，使用have been done时主语为复数。现在完成时被动语态用来强调一个发生在过去的被动性动作对现在造成的影响。被动语态是动词的一种形式，用以说明主语与谓语动词之间的关系。英语的语态共有两种：主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。被动语态是动词的一种特殊形式，一般来说，只有需要动作对象的及物动词才有被动语态。汉语往往用"被""受""给"等被动词来表示被动意义。现在完成时：是过去的动作或状态持续到现在并且已经完成，对现在造成的影响，可能持续发生下去。它的构成是：主语+助动词（have/has）+动词的过去分词（done）。过去发生的某一动作对现在造成的影响或结果或到现在为止已经发生或完成的动作。表示过去发生的、持续到现在的动作或状态。该用法的现在完成时表示一个过去发生的动作在过去已经完成，并且这个动作对现在仍有影响或结果，同时说话者强调的或感兴趣的就是这个影响或结果，如汉语说“他已离开这个城市了”，其中的“离开”肯定发生了，它对现在的影响或结果就是“他现在已不在这个城市了”。

被动语态的现在进行时、现在完成时的状态 一般现在时：be(am are is+done) 一般过去时：was/were+done 现在进行时：am/are/is+being+done 过去进行时：was/were+being+done 现在完成时：has/have+been+done 过去完成时：had+been+done 一般将来时：will+be+done;is/are/is+going to be done；is/are/am+to+be done 过去将来时：would+be+done; was/were going to be done; was/ were to be done 现在完成进行时：has/have been being done 过去完成进行时：had been being done 将来进行时：will be doing 将来完成时：will have/has been done 望采纳！ 现在完成时和现在完成进行时的被动语态结构? 现在完成时为：have/has +been 指过去发生的事，对现在产生了影响，或一直到现在。 例：I have been learnt English for five years. 我已经学了五年英语。（现在依然在学。) 现在完成进行时为：have/has +been +doing指过去发生的事，到现在这个点还在做。 例：She has been skating for three hours. 她已经滑了三个小时。(现在还在滑。） 希望能给到你提供帮助~ 被动语态和现在完成时的被动语态的区别 第一个是一般时态的被动语态 第二个是现在完成时的被动语态，表示被动的动作发生在说话之前（即现在的过去），强调对现在造成的影响和结果。 被动语态造句,一般现在时,现在进行时,一般过去时,过去进行时,现在完成时,过去进行时 (被动语态变主动语态) 一般现在时：Teachers are needed badly here.这儿及需要教师。 现在进行时：A modern hospital is being built in this area. 一般过去式：A modern hospital was built in this area last year. 过去进行时：A modern hospital was being built in this area then. 现在完成时：A modern hospital has been built in this area. 现在完成时被动语态 过去进行时 6个 The buiding has been set up for several years. The article has been written for months. The work has been done for years. The TV has been repaired for hours. The haie has been cut. The clothes have been done. I was doing homework when you called. I was doing housework when you called. I was cleanning the room when you called. I was doing the laundry when you called. I was playing puter games when you called. 希望能够帮到楼主 英语现在进行时的被动语态跟完成时态的进行时怎么表示。 The cinema is being built now. 现在进行时的被动。 电影院正在被建中。 We have been waiting for you since we had lunch. 完成时的进行时。 我们从吃完午饭一直在等你。 现在完成时的被动语态 The experiment has been done suessfully. 这个实验做得很成功。 Tom"s novel has not been published. 汤姆的小说还没有被出版。 1. 主动句：He has repaired the machine for o hours. （他修理这台机器已有两小时了） 被动句：The machine has been repaired for o hours. （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：The books have been borrowed by the teacher. （那些书被老师借走了） 现在完成时的被动语态 主动语态表示主语为动作的执行者；被动语态表示主语为动作的承受者。现在完成时的被动语态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……”。 现在完成时的被动语态结构是“主语＋has/have＋been＋过去分词”。使用现在完成时的被动语态应注意下面几点： 1. 现在完成时的被动语态同主动语态一样强调过去的动作对现在的影响。 They have just cleaned and repaired the watch. → The watch has just been cleaned and repaired (by them). Tom has written the letter． → The letter has been written by Tom． 分析：此表刚擦洗修理，那就必然是用现在完成时，my watch是动作的承受者，在被动语态句中作主语。 2. 被动语态没有完成进行时态，主动语态的现在完成进行时改为被动语态时要用现在完成时，依此类推，主动语态的过去完成进行时改为被动语态时用过去完成时。如： He has been writing the report for o days. → The report has been written by him for o days. 3. 现在完成时的被动语态的用法 1) 表示一个被动的动作发生在说话之前,强调对现在造成的影响和结果。如: The door has been locked. 门被锁上了。 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。如: The important problem has been discussed for nearly o weeks. 那个重要的问题已经被讨论近两个星期了。 How long has the machine been used? 这机器使用有多久了?可。 3) 注意与一般过去时的被动语态的区别。一般过去时的被动语态所表示的动作或状态与现在的情况没有联络,而现在完成时的被动语态则强调与现在情况的联络。如: The bridge was built last year. 这桥是去年建成的。 The bridge has been built. 这桥已经建好了。 No books have been bought since last week. 自上周以来,没有人来买过书。 你好: 举个例子吧: His shoes have been shined by his wife. 翻译: 他的鞋子已经被他妻子擦亮了. 希望对你有帮助! have been done had been done

你的问题其实是两个：1.现在完成时和过去完成时的区别. 2.主动语态和被动语态的区别. 现在完成时,指动作发生在过去,到现在已经完成,且该动作造成影响或产生结果. 过去完成时,动作也发生在过去,但是它是到过去另一个时间已经完成（即没有延续到现在的概念）,且对当时产生影响或造成结果. 例如： I have finished my homework so far （到现在为止,我已经完成作业了） I had finished my homework by 10 o"clock (10点已经过去,到 10点为止完成,故过去完成时） 你可以假设一下（因为初中不讲这个）,如果到将来某时间完成,会用什么时态呢? 将来完成时：比如：i will have learned English for 6 years by the end of this term. 英语中及物动词都带宾语,因此及物动词都有被动语态.现在完成时的被动语态构成是have/has been done ; 过去完成时被动语态结构是had been done.(将来完成时被动语态结构是will have been done)

一般现在时:Millie washes her clothes . 一般将来时:Milie will wash her clothes tomorrow. 一般过去时:Millie washed her clothes yesterday. 现在进行时:Millie is washing her clothes now. 过去进行时:Millie was washing her clothes this time yesterday. 现在完成时的被动语态:The clothes have been washed by Millie.

八种时态的被动语态：（变 be 的时态即可，done不动）1、一般现在时：am / is/ are + doneGranny looks after the little girl every day.→The little girl is looked after by Granny every day.奶奶每天照顾那个小女孩。2、一般过去时：was /were + doneMy aunt brought up me.→I was brought up by my aunt.我是由姑姑带大的。3、一般将来时：will +be doneThey will give me a chance to play in this game again.→I will be given a chance to play in this game again.我将要获得再一次参赛的机会。4、一般过去将来时：would+ be doneThe manager said they would complete the project by the end of the year.→The manager said the project would be completed by the end of the year.经理说这项工程将会在年底被完成。5、现在进行时：am / is / are + being + doneThe radio is broadcasting English lessons.→English lessons are being broadcasted on the radio.英语课正在广播中。6、过去进行时：was / were + being + doneThe workers were mending the road.→The road was being mended.这条路正在修。7、现在完成时：have /has + been + doneSomeone has told me the sports meeting might be put off.→I have been told the sports meeting might be put off.有人告诉我运动会可能会被延迟。8、过去完成时：had + been + doneWhen I got to the theatre, I found they had already sold out the tickets.→When I got to the theatre, I found the tickets had already been sold out.当我到剧院时，我发现票已经卖完了。扩展资料：被动语态记忆口诀及语态转换时应注意的问题：1、一般现在时、一般过去时用be +及物动词的.过去分词，be有人称、时、数变。2、完成时态have（has）done，被动将been加中间。3、一般将来shall（will）do，被动变do为be done。4、将来进行无被动，shall（will）be doing。5、现在完成时，被动 have（has）been done。6、现、过进行be doing，被动be加being done。7、情、助、有、是妥安排，一律随新主语变。8、否定助后加not，疑问一助置主前。9、主语恰是疑问词，直陈语序主在前。10、一般情助加be done，双宾多将间宾变。11、复合宾语宾变主，宾补、主补相应变。第二句“be有人称、时、数变”即be有人称、时态和单、复数的变化。“情助”是指情态动词和助动词“must，may，can，shall，will”等一律随新主语（多是主动句中的宾语）来变化。“疑问一助置主前”是说有两个助动词的话，应把主语放在第一助动词之后或把第一助动词置于主语之前。

一般现在时被动语态:主语+be+done一般过去时被动语态:主语+was/were+done现在完成时被动语态:主语+have/has+been+done一般将来时被动语态:主语+will/shall+be+done例：一般现在时态的被动语态We are allowed to go out.我们被允许外出The questions were answered in public.问题被公开答复了 一般过去时被动语态The door was opened.门被开了Some new computers were stolen last night. 一些新电脑在昨晚被盗了。现在完成时被动语态His bikes have been sold out. 他的自行车已都卖完了My watch has been repaired. 我的表修好了。一般将来时被动语态The new film will be shown next Thursday. 这部新电影将在下周四上映。The problem is going to be discussed at the meeting tomorrow. 这个问题将在明天的会议上被讨论。

选B.一般现在时被动语态的构成：is/are +过去分词； 现在完成时被动语态的构成：has/have+been+过去分词.分析：上题考的是appear to do sth.结构,根据句意可知,这位母亲一定是已经被告知了所有的事实,所以用了现在完成时的被动语态（have been told）,而A是动词不定式之后的被动,表示事情或事实将被告知.如果是将被告知,那为什么要让母亲知道所有的事实呢?将被告知,表明动作还没有发生 ,事情只有先被告知而母亲又不完全了解的情况下,才迫于无奈说出所有真相.

我给你从百度上粘过来的：肯定句：主语+have/has+过去分词否定句：主语+have/has not +过去分词疑问句：Have/Has+主语+过去分词7. 现在完成时(1) 现在完成时的句型结构①肯定句：主语+ have/has+ 过去分词②否定句：主语+ have/has+ not+过去分词③疑问句：Have/Has +主语+过去分词(2) 现在完成时的用法①表示到目前为止曾经有过的或未曾有过的经历和体验。常和never, ever, several times等连用。如：I"ve never been to Africa. Have you ever been to Tokyo?I"ve been there three times. ②. 表示某动作从过去开始，现在刚刚完成，对现在有一定的影响。常与just, already, yet, so far等词语连用。 如：He has just finished his new book. 注意：just now用于过去时。③.表示某动作从过去开始，一直持续到现在，可能还会持续下去。通常与for或since连用。如：I have lived in Qingdao for 6 years. /since 6 years ago/since 2003/since I came to this city.It is/has been …+ since….It"s been seven years since we last saw each other. It"s six years since he was a teacher. 注意:for+一段时间，since后接一个过去的时间点或一般过去时的句子。④ 在表将来的时间状语和条件状语从句中代替将来完成时。如：You can go home when you have finished your work. 比较：You can go home when you finish your work. 主动语态变被动语态：(1) 一般现在时的被动语态：am [is, are]+过去分词English is taught in our school. 我们学校学英语。We are taken good care of at school. 我们在学校受到很好的照顾。(2) 一般过去时的被动语态：was [were]+过去分词He was taken to the police station. 他被带到了警察局。The house was built ten years ago. 这座房子是10年前建的。(3) 一般将来时的被动语态：will be+过去分词A new building will be built here soon. 不久这里将建一栋新楼。The meeting will be held at two this afternoon. 会议将于今天下午2点举行。(4) 现在完成时的被动语态：have [has]been+过去分词All the work has been done now. 所有的工作现在都做好了。Have the letters been posted? 信都寄了吗？(5) 过去完成时的被动语态：had been+过去分词He said the work had been finished. 他说工作已完成了。(6) 现在进行时的被动语态：am [is, are] being+过去分词My watch is being repaired by him. 我的表正在由他修理。The plan is now being discussed. 计划现在正在讨论。(7) 过去进行时的被动语态：was [were] being+过去分词He said that the man was being operated on. 他说那个人正在动手术。He told me that a new station was being built. 他说正在修建一个新车站。(8) 过去将来时的被动语态：would be+过去分词He said that the meeting would be held next week. 他说会议将于下周举于。

(2)常与现在完成时连用的时间状语有：since, for, during, over等引导出的短语；副词already, yet, just, ever, now, before, often, lately, recently等；状语词组this week (morning, month, year), so far, up to now, many times, up to the present等。例如： 1)I haven"t been there for five years. 2)So far, she hasn"t enjoyed the summer vacation. 3)There have been a lot of changes since 1978. (3)完成时态可用在下列结构中： This (That, It) is (was) the first (second…) time +定语从句；This (That, It) is (was) the only (last) + n +定语从句；This (That, It) is (was) +形容词最高级+ n +定语从句。如果主句的谓语动词是一般现在时，从句的谓语动词通常用现在完成时；如果主句谓语动词是一般过去时，从句谓语动词通常用过去完成时。例如： (1)This is one of the rarest questions that have ever been raised at such a meeting. (2)There was a knock at the door. It was the second time someone had interrupted me that evening. 2.过去完成时 (1)表示过去某时间前已经发生的动作或情况，这个过去的时间可以用by，before等介词短语或一个时间状语从句来表示；或者表示一个动作在另一个过去动作之前已经完成。例如： 1)We had just had our breakfast when Tom came in. 2)By the end of last year they had turned out 5, 000 bicycles. (2)动词expect, hope, mean, intend, plan, suppose, wish, want, desire等用过去完成时，表示过去的希望、预期、意图或愿望等没有实现。例如： I had meant to take a good holiday this year, but I wasn"t able to get away. 另外两种表示“过去想做而未做的事”的表达方式是： 1)was / were + to have done sth,例如： We were to have come yesterday, but we couldn"t. 2)intended (expected, hope, meant, planned, supposed, wished, wanted, desired) + to have done sth,例如： I meant to have told you about it, but I forgot to do so. (3)过去完成时常用于以下固定句型： 1)hardly, scarcely, barely + 过去完成时+ when + 过去时。例如： Hardly had I got on the bus when it started to move. 2)no sooner +过去完成时+ than +过去时。例如： No sooner had I gone out than he came to see me. 3)by (the end of ) +过去时间，主句中谓语动词用过去完成时。例如： The experiment had been finished by 4 o"clock yesterday afternoon. 3.将来完成时 将来完成时表示在将来某一时刻将完成或在另一个未来的动作发生之前已经完成的动作；也可以用来表示一种猜测。常与将来完成时连用的时间状语有：by (the time / the end of ) +表示将来时间的短语和句子；before (the end of ) +表示将来时间的词语或句子；when, after等加上表示将来动作的句子等。例如： 1)By this time tomorrow you will have arrived in Shanghai. 2)I shall have finished this composition before 9 o"clock. 3)When we get on the railway station, the train will probably have left. 4.完成进行时 完成进行时是完成时的强调形式，有现在完成进行时，过去完成进行时，将来完成进行时。 (1)现在完成进行时表示过去某一时刻之前开始的动作或状态一直延续到过去某一时刻。例如： I have been looking for my lost book for three days, but I still haven"t found it. (2)过去完成进行时表示过去某一时刻之前开始的动作或状态一直延续到过去某一时刻。例如： It had been raining cats and dogs for over a week and the downpour had caused landslides in many places. (3)将来完成进行时表示在将来某一时刻之前开始的一个动作或状态一直延续到将来某一时刻。例如： By the time you arrive tonight, she will have been typing for hours. 四：时态一致 时态一致是英语四、六级考试的一个重要内容。通常应由主句谓语的时态决定从句的谓语时态。一般原则是： 1、当主句谓语使用现在时或将来时，从句的谓语根据具体情况使用任何时态 He says that he lives in Wuhan. We hope that there will be many people at your party today. “Did you hear that Bill finally sold the house?” “Yes, but I don"t know who bought it.” “There"s a lot of excitement on the street.” “There certainly is. Do you suppose the astronauts have returned?” 2、当主句谓语使用过去时的时候，从句的谓语必须使用过去范围的时态 He said he was writing a novel. The teacher wanted to know when we would finish the experiment. He said his father had been an engineer. 3、当从句是表示没有时间概念的真理时，从句的谓语应使用一般现在时。例如： The teacher told them since light travels faster than sound, lightning appears to go before thunder. 注：在此种情况下，即使主句谓语用了过去式的各种时态，从句谓语也应用一般现在时。 4、从句谓语只能用虚拟语气的情况 利用时态一致原则确定从句动词时态时，还应注意，若主语动词是表示命令、请求、要求、建议、劝告等的动词，从句谓语只能用虚拟语气，不能遵循时态一致原则。例如： We insisted that we do it ourselves. 动词的语态 语态也是动词的一种形式，英语有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，而被动语态表示主语是动作的承受者。 1)We use electricity to run machines. (主动语态) 2)Electricity is used to run machines. (被动语态) 1.不能用于被动语态的动词和短语 (1)在英语中，不及物动词不能用于被动语态，但有些不及物动词(包括短语)容易引起误用。如：appear, belong, belong, die, escape, fall, happen, last, remain, succeed, occur, come true, take place, consist of。 (2)某些表示状态或特征的及物动词，如：become, contain, cost, fit, have, resemble, suit也没有被动语态。 2.被动语态的时态形式 常用的被动语态有表1所列的几种时态形式。 表1 时?SPAN lang=EN-US> 一般时 进行时 完成时 现在 am asked am being asked is asked is being asked are asked are being asked 过去 was be asked was being asked were be asked were being asked 将来 shall be asked shall have been asked will be asked will have been asked 过去 should be asked should have been asked 将来 would be asked would have been asked 3.短语动词的被动语态 短语动词转换为被动语态时，通常被看作是一个动词，后面的介词或副词不能拆开或省略。例如： 1)So far no correct conclusion has arrived at. 2)All the rubbish should be got rid of. 4.“get + -ed分词”的被动语态 “get + -ed分词”结构强调动作的结果，而非动作本身，常用来表示突发性的，出乎意料的偶然事件。例如： The boy got hurt on his way home from work. 另外，“get + -ed分词”还可用于谈论为自己做的事，是主动的行为而不是被动的行为。例如： get dressed(穿衣服) get divorced(离婚) get engaged(订婚) get confused(迷惑不解) get lost(迷路) get washed(洗脸) get married(结婚) 5.能带两个宾语和复合宾语的动词改为被动语态 (1)能带两个宾语的动词改为被动语态时，一次只能由一个宾语作主语，另一个宾语被保留下来。例如： 1)We showed the visitors our new products.(主动语态) 2)The visitors were shown our new products.(被动语态) 3)Our new products were shown to the visitors.(被动语态) (2)能带复合宾语的动词改为被动语态时，原来的宾语补足语变为主语补足语。例如： 1)The teacher appointed him League secretary.(主动语态) 2)He was appointed League secretary.(被动语态) 6.被动语态与系表结构的区别 (1)The novel was well written.(系表结构) (2)The novel was written by Diskens.(被动语态) 7.少数动词的主动语态有时有被动的意思 例1：The book is selling remarkably well. 例2：The song sounds very beautiful. 能这样用的动词还有read(读起来)，clean(擦起来)，wash(洗起来)，write(写起来)。 例3：My watch needs cleaning. (= My watch needs to be cleaned). 能像need这样用的动词还有：want, require, deserve, do, owe, bind等。 例4：The meat is cooking. 例5：The book written by the professor is printing.在英语中被动语态分时态,我给你举些例子: (1)一般现在时:This song is often sung by children.孩子们常唱这首歌. (2)一般过去时:This house was built in 1958.这房子建于1958年. (3)一般将来时:Many buildings will be built in my home town.在我的家乡,许多大楼将要建成. (4)过去将来时:The old scientist said that he would be invited to vist their country before long.那位老科学家说不久他将应邀访问他们的国家. (5)现在进行时:The proposal is being considered now.正在考虑这个提案. (6)过去进行时:Mr Wu was in hospital .When we went to see him,he was being operated on.吴先生住院了.我们去看他时,他正在动手术. (7)现在完成时:Have the letters been posted ?信已经寄出去了吗? (8)过去完成时:He came and told us that the work had been finished.他来告诉我们,工作已经完成. (9)将来完成时:By the end of this year,the tall building will have been built.到今年年底,这幢高楼将建成. (10)过去将来时:The boy told mother that his homework have been finished by ten o"clock.男孩告诉妈妈到10:00他将做完作业.

有时候被动语态后有by........可以分辨，再就是牢记被动语态的结构。

现在完成时表示到现在为止已经完成的被动动作，它的助动词和现在完成时相同，都是have 或has，区别在于被动语态要加上been动词，如She has been underrated by her classmates for 3 years. I have been invited to some of the most important events in this city.唯一需要注意的就是助动词必须与主语搭配。结构都是have/has+been+动词的过去分词

一、完成时被动语态的构成，以work为例：work的完成时：haveworked（表示完成的助动词have+过去分词）work的被动语态：beworked（表示被动的助动词be+过去分词）完成时被动语态：have+beenworked（就是说，把表示完成的助动词have放在被动语态前，由于have要求后面的动词是过去分词，因此被动语态的助动词be就需要变成相应的过去分词been，即“表示完成的助动词have+表示被动的助动词been+过去分词”）二、结构上的共同点与不同点1、共同点：二者都由助动词have+过去分词构成主动语态：havedone（have+do的过去分词done）被动语态：havebeen【done】（have+be的过去分词been+【done】）2、不同点：主动语态中只有一个表示完成的助动词have；被动语态中的既有表示完成的助动词have，还有表示被动的助动词been三、意思上区别主动语态表示“已经做过某事”，被动语态表示“某事已经被做过”。如：四、句子结构的区别主动语态构成是：主语（行为者）+have+过去分词+宾语（行为对象）被动语态构成是：主语（行为对象）+have+been+过去分词+by+介词宾语（行为者）——主动语态的宾语变成被动语态的主语，主动语态的主语变成被动语态中介词b的宾语例如：Wehavedonethejob.我们已经做完了那件工作。Thejobhasbeendonebyus.那件工作已经被我们做完。HehasgotaCDforhisbirthday.他收到一张作为生日礼物的CD。ACDhasbeengotforhisbirthday(byhim)。一张作为生日礼物的CD已经(被他)收到。

Ihavebeenexcitedseveraldays...为什么excited前面加been变成被动语态？因为have+过去分词构成现在完成时；be+过去分词构成被动语态；哪个词既可以管have构成现在完成时，又要管后面的过去分词构成被动语态？非【been】莫属，你说是吗？所以，excited前面加been变成被动语态。如果我的回答对你有所帮助，请点击本页面中的“选为满意回答”按钮，谢谢！

现在完成时的被动语态:在have(has)后加been再加动词的过去分词将来时的被动语态:也在have(has)后加been再加动词的过去分词

现在完成时的被动语态例子如下：1. The book has been read by many people.2. The car has been repaired by a mechanic.3. The cake has been baked by my sister.4. The movie has been watched by millions of people.5. The letter has been written by my friend.6. The house has been cleaned by a maid.7. The meal has been cooked by a chef.8. The song has been sung by a famous singer.9. The painting has been admired by many people.10. The computer has been fixed by a technician.11. The problem has been solved by the experts.12. The package has been delivered by the postman.

被动语态 1.被动语态 (1).被动语态表示句子的主语是谓语动词所表示的动作承受者. (2).被动语态基本结构：be+及物动词的过去分词 (如果是不用物动词,其过去分词应带有相应的介词) (3).被动语态中的be 是助动词,有人称、数和时态的变化. 一般现在时被动语态为：am/is/are+过去分词 一般过去时被动语态为：was/were+ 过去分词 与情态动词连用的被动语态：情态动词+ be + 过去分词 (4).被动语态中动作的发出者或执行者做介词by的宾语,放在句 末,by 表示“由,被”的意思 如何理解被动语态? 为取胜更清晰、更深刻地理解被动语态的含义,可以将主动语态和被动语态的句子结构进行比较. 主动语态：主语+ 谓语动词 + 宾语 + 其他成分 被动语态：主语+ be +过去分词 + by +宾语 +其他成分 如：Many people speak English. 被动语态 English is spoken by many people. 4.be used for doing用来做…(是被动语态) 如： Pens are used for writing.笔是用来写的. Pens aren"t used for eating.笔不是用来吃的. 5.给某人某样东西 give sth.to sb.如：I gave a pen to him.我给他一支笔. give sb.sth.I gave him a pen.我给他一支笔. 6.all day 整天 7.salty adj.咸的 salt n.盐 8.by mistake 错误地 如： I took the umbrella by mistake.我不小心拿错了雨伞. 9.make sb./sth.+形容词 使…怎么样 It made me happy.它使我高兴 make sb./sth.+名词 让…做… It made me laugh.它让我发笑 10.by accident 意外 偶然 I met her by accident at bus stop. 我在公共汽车站意外地见到了她. 11.not…until… 直到…才做… 如： I didn"t go to bed until I finished my work. 我直到完成我的工作才去睡觉. 12.according to +名词 根据… 如：according to an legend according to this article根据这篇文章 根据一个神话 13.over an open fire 野饮 14.leaf n.叶子 复数形式 leaves 15.nearby adj.附近的 如：the nearby river 16.fall into 落入 掉进 如：The leaf fell into the river.叶子落入了河里.fall down 摔倒 如：She fell down from her bike. 她从她自行车摔倒了. 17.quite 非常 adv.与冠词a连用时,冠词a必须放在它的后面 如：quite a beautiful girl 一个漂亮的女孩 very 非常 adv.与冠词a连用时,冠词a必须放在它的前面 如：a very beautiful girl 一个漂亮女孩 注：当不与冠词a 连用时,两者可以互用 如： I am very happy.=== I am quite happy.我非常高兴. 18.in the way 这样 19.pleased adj.表示外部因素引起人发自内心的欣慰和愉快 pleasant adj.愉快 高兴 指天气、时间、旅行令人高兴愉快 please v.使高兴 使同意 20.battery—operated adj.电池控制的 是名词+动词的运动分词构成的合成形容词 21.in the sixth century 在第6世纪 22.travel around 周游 23.more than === over 超过 如： more than 300 == over 300 超过300 24.including prep.介词 包括 可以与名词和动名词连用 如:Six people,including a baby,were hurt. 6个人包括一个小孩受伤了. 25.have been played 被上演 是现在完成时的被动语态 现在完成时的被动语态的结构：have /has been +过去分词 26.be born 出生 He was born in Canada.他在加拿大出生 27.safety n.安全 safe adj.安全的 28.knock into 撞上(某人) 29.divide sth.into … 将…划分成.. 通常指将一个整体分成几个对应相对的部分 如： Let"s divide ourselves into 4groups.让我们把我们自己划成4组. 30.since then 自从那以后 常与完成时态连用 如： Since then,I have left Beijing.自从那以后,我已经离开了北京.

一、概念主动语态表示主语为动作的执行者；被动语态表示主语为动作的承受者。现在完成时的被动语态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……”。如：The new school has been set up. 新学校已经建成了。二、形式现在完成时的被动语态的肯定式为：have/ has +been +done。如：The experiment has been done successfully. 这个实验做得很成功。现在完成时的被动语态的否定式为：have/ has +not +been +done。如：Tom"s novel has not been published. 汤姆的小说还没有被出版。现在完成时的被动语态的一般疑问句需将have /has提到主语的前面。如：Has his bike been repaired? 他的自行车修好了吗?现在完成时的被动语态的特殊疑问句为：疑问词+have /has +been +done? 如：Who has been invited? 谁受到了邀请?三、注意在使用现在完成时的被动语态时要注意以下四点：1. 过去分词前的助动词的形式是have /has +been，不可漏掉其中的任何一个。【误】Many new buildings been built since 1980.【正】Many new buildings have been built since 1980.【析】谓语部分结构不全，时态部分不完整。2. 必须表示被动。如：【误】Something bad has been happened to him.【正】Something bad has happened to him.【析】被动语态误用。happen为不及物动词，不及物动词没有被动语态。【误】The door has been opened of itself.【正】The door has opened of itself.【析】有些动词如open，break，drop等既可以作及物动词，又可以作不及物动词，若不强调谁是动作的发出者，我们通常用主动语态。of itself意思是“自动地”，因此，此句不可用被动语态。【误】I have introduced to Mr Smith.【正】I have been introduced to Mr Smith (by Mr Wang).【析】introduce为及物动词，I是introduce动作的承受者，应用被动语态。3. 由finish，buy, start, begin，post，return，borrow, join，marry，open等短暂性动词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如for four days，for a long time等连用，如需表达这样的意思，可改变动词或时态。如：译：这本书买了多久了?误：How long has this book been bought?正：How long ago was this book bought?但这类动词的否定式可与since或for引导的表示一段时间的状语连用。如：No books have been bought since last week. 自上周以来，没有人来买过书。4. 短语动词是一个不可分割的整体，在被动结构中要保持完整性，不可省略短语动词中的介词或副词。如：The orphan has been well looked after. 这个孤儿一直受到很好的照顾。

被动语态是动词的一种形式，用以说明主语与谓语动词之间的关系。被动语态是动词的一种特殊形式，一般来说，只有需要动作对象的及物动词才有被动语态。汉语往往用"被"、"受"、"给"等被动词来表示被动意义 。被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只改变be的形式，过去分词部分不变。疑问式和否定式的变化也如此。现在完成时是过去的动作或状态持续到现在并且已经完成，对现在造成的影响，可能持续发生下去。在英语时态中，“时“指动作发生的时间，”态“指动作的样子和状态。完成时态的构成分为两部分：一是助动词，二是实义动词的过去分词-ed。具体来说，用助动词have表示“时”，以表明动作发生的时间是在过去、现在还是将来；用过去分词来表示动作的“态”，以表明该动作已经完成。它的构成是：主语+have/has+动词的过去分词

过去完成时的被动语态由had been +动词的过去分词构成,现在完成时的被动语态由have/has been +动词的过去分词构成

现在完成时指的是时态，而现在完成的被动语态指的是语态。

现在完成进行时为：have/has +been +doing指过去发生的事,到现在这个点还在做. 例：She has been skating for three hours.她已经滑了三个小时.(现在还在滑.） 现在完成进行时是没有被动语态的,如果有现在完成进行时的主动结构的句子变为被动结构,可以用现在完成时. 例：We have been discussing the problem for 2 days. 变为：The problem has been discussed for 2 days. 另外,将来进行时也没用被动语态. 例：We shall be discussing it tomorrow. 变为：It will be discussed tomorrow.

现在完成时为：have/has +been 指过去发生的事,对现在产生了影响,或一直到现在. 例：I have been learnt English for five years.我已经学了五年英语.（现在依然在学.) 现在完成进行时为：have/has +been +doing指过去发生的事,到现在这个点还在做. 例：She has been skating for three hours.她已经滑了三个小时.(现在还在滑.） 希望能给到你提供帮助~

I have been learning English for five years.我已经学了五年英语.（现在依然在学.)

现在完成时为：have/has +been 指过去发生的事,对现在产生了影响,或一直到现在. 例：I have been learnt English for five years.我已经学了五年英语.（现在依然在学.) 现在完成进行时为：have/has +been +doing指过去发生的事,到现在这个点还在做. 例：She has been skating for three hours.她已经滑了三个小时.(现在还在滑.） 希望能给到你提供帮助~

现在完成进行时：表示动作从过去一直进行到现在,还可能继续进行下去（强调的是进行）.如： I have been waiting for you. （我一直在等着你） 现在完成时：表示过去动作影响现在；过去动作或状态持续到现在,动作或状态可能已经结束,也可能继续动作或状态. 如： I have seen the film.表示过去动作影响现在 I have lived here for two years.过去动作或状态持续到现在,也可能继续动作或状态. 被动语态当然存在,只要有宾语,就可能存在被动语态.（当然,理论上存在,其实很少使用的） 我的显示器已经使用了8年. 两种时态都可以,看强调.进行就表示现在还在进行中的.而完成时只是交待动作持续而已. 如： The play has been being performed for some hours.(一直在演呢） The play has been performed for some hours.(动作可能已经结束,也可能继续动作或状态)

He has been doing the same thing 。

被动语态结构：助动词be+及物动词的过去分词；情态动词+be+及物动词的过去分词。应用范围：表示被动的情况，一般是及物动词有被动语态，切记不及物动词与一些固定词组是没有被动语态的。例如：happen，take place。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。巧记为：主动、主动、主去动。例如：Many people speak English.谓语：speak的动作是由主语many people来执行的。被动语态表示主语是动作的承受者，即行为动作的对象。巧记为：被动、被动、主被动。例如：English is spoken by many people.主语English是动词speak的承受者。被动语态口诀一般现在时、一般过去时用be +及物动词的过去分词，be有人称、时、数变。完成时态have（has）done，被动将been加中间。一般将来shall（will）do，被动变do为be done。将来进行无被动，shall（will）be doing。现在完成时，被动have（has）been done。现、过进行be doing，被动be加being done。情、助、有、是妥安排，一律随新主语变。否定助后加not，疑问一助置主前。主语恰是疑问词，直陈语序主在前。一般情助加be done，双宾多将间宾变。复合宾语宾变主，宾补、主补相应变。第二句“be有人称、时、数变”即be有人称、时态和单、复数的变化。“情助”是指情态动词和助动词“must，may，can，shall，will”等一律随新主语（多是主动句中的宾语）来变化。“疑问一助置主前”是说有两个助动词的话，应把主语放在第一助动词之后或把第一助动词置于主语之前。
