行时：They have been reading books for two weeks. 将来完成进行时：They will have been reading books for two weeks. （4） 过去将来完成进行时：She would have been thinking about it by the end of the year. 现在完成进过去将来完成进行时、现在和将来完成进行行时：She has been thinking about it by the end of the year. 将来完成进行时：She will have been thinking about it by the end of the year. 本篇的练习到此为止，同学们都记清三个时态的用法了吗？

同为完成进行时，过去将来完成进行时、现在完成进行时和将来完成进行时非常相似。不过归根结底，只要弄清楚了时间点，就很好分辨了。 过去将来完成进行时 表示动作从过去某时间开始一直延续到对于过去来说的将来的某一个时间。 基本形式：should/would + have + been + doing 现在完成进行时 基本形式：have/has + been + doing 表示过去某时间点开始的动作或状况一直持续到现在（可能继续或就此停止） 将来完成进完成进行时，过去将来完成进行时、现在完成进行时和将来完成进行行时 基本形式：shall/will + have + been + doing 表示某种状况一直持续到说话人所提及的时间。 例句对比： （1）杰克

本书就已经被读了两周了。 8. She told me she would have been teaching in that university for 20 years by that summer. 她告诉我到那年夏天她过去将来完成进行时和过去将来完成时，还特地把过去将来完成在那所大学教书就满20年了。 9. I would have forgotten my mother's birthday if you hadn't reminded me. 如果你不提醒我，我会忘了我妈妈的生日。 10. She would have been travelling for two weeks. 她已经旅游2周了。

行时是不是和过去将来完成时的被动态有点相似呢？让我们来通过例句感受其中的不同： （1） He said he would have been doing homework tomorrow afternoon. 他说明天下午他会在写过去将来完成进行时 表示动作从过去某时间开始一直延续到（对于过去来说）将来的某一个时间。 基本形式：should/would have been + v-ing 过去作业。 The teacher said the assignment would have been handed in before next week. 老师说作业在下周前交。 （2） He said that he would have been working. 他说他会在工作。 The work would have been finished before 4 o'clock. 这个工作4点前会结束。 （3） We would have been having a meeting tomorrow. 明天我们会在开会。 The meeting would have been finished before 10 o'clock. 会议会在10点前结束。 （4） She would have been shopping by Friday. 她星期五前会在购物。 The house would have been bought next week. 这个房子下周会被买走。 （5） He said that he would have been cleaning his room. 他说他会在打扫房间。 He said that his room would have been being cleaned for 3 hours. 他说他的房间已经被打扫3小时了。 由例句来看，分辨过去将来完成进行时和过去将来完成时的被动态的重点在于找出主语。确定好了主语，就能轻松的看出是否被动了。

活了12年了。 3、I heard by July you’d have been teaching here for ten years.   我听说到七月份，你就在这里教了10年书了。 4、“What interesting job have you found?” Helen asked him; he knew she would have been thinking about it.  “你找到什么有趣的工作啦?”海伦向他问道。他知道海伦一定会一直想这过去将来完成件事的。  解析：这个里面，“would have been+现在分词”结构除用于表示过去将来完成进行时外，有时其中的 would 也可能是情态动词，具有情态意义，比较表示推测或猜想等。 5、If I had known how he felt, I would never have let him adopt those children. 我要是知道他的想法，我是决不会让他领养那些孩子的。 解析：若表示与过去事实相反的虚拟语气，此时条件从句的谓语用过去完成时(had+过去分词)，而主句谓语则通常用过去完成时（would+have+过去分词），当然，主句谓语也可根据情况使用“should (could, might)+have+过去分词”。

用得相对比较少，通常主要用于转述方面，即用于间接引语中。结构如下： 过去将来完成时由“would+have+过去分词”构成。 二、 通过例句来简单辨析一下 ①“He told me that I should have written down all the details yesterday.” 他告诉我说，我昨天应该记录下所有的细节。 ②“He said he would have been living in this thriving city for 13 years by the next year” 他说，到下一年，他就在这个欣欣向荣的城市生活了13年之过去将来完成进行时表示动作从过去某一时间开始一直延续到对于过去来说的将来久了。 解析：首先例句1，表示的是过去将来完成时。它表示的是在过去看来，“记下细节”这个动作已经完成。而例句2表示的是过去将来完成进行时，它所表示的是生活在这里的这一动作从过去某个时间开始已经持续了很久，但是是否会继续持续下去，则要结合上下文来分析。

行时的被动态。基本形式：should/would have been being done. 请看例句： 1. He said the trees would have been being planted on March 12th on the mountain this year by the students, because the school had already decided. 他说今年3月12日会有很多树苗被学生种下，因为学校已经决定这项活动了。 2. She said that by the end of last weekend, the book would have been being read for 2 weeks. 她说直到上周末，这本书就已经被读了两周了。 3. This topic would have been being considered for a month. 这个话题已经被考虑了1个月了。 4. Tom's room would have been being cleaned. 汤姆的房间会被打扫。 5. The play would have been being performed for 2 hours. 这场表演会持续两小时。 6. Up to that time those books had been being translated. 直到那时，这些书还在被翻译。 7. The letter had been being written till two o'clock. 写这封信写到了2点。 由基本形式转过去将来完成进行时，表示动作从过去某时间开始一直延续到对于过去来说的将来换为被动态还是挺简单的，不过这里需要注意的是被动态的形式为should/would have been being done。请不要和过去将来完成时的被动态would + have + been + done混淆。前者为持续性动作，而后者并无持续性的意思。

行时表示就过去某一时间而言，将来某一时刻或某一段时间正在进行的动作。主要用于宾语从句 中，尤其多用于间接引语中。其结构如下所示: 1肯定形式：.由主语+should(would)+be+现在分词 2.否定形式：主语+should(would)+not+be+现在分词 3.疑问形式：should(would)+主语+be+现在分词（+其他） 二、通过例句来辨析 过去将来完成进行时态 “He said he would have been living in this thriving city for 13 years by the next year” 他说，到下一年，他就在这个欣欣向荣的城市生活了13年之久了。 表示的是过去将来完成进行时，它所表示的是生活在这里的这一动作从过去某个时间开始已经持续了很久，但是是否会继续持续下去，则要结合上下文来分析。 过去将来进行时用于间接引语 ： “She asked me what I should be doing tomorrow afternoon. 她问我次日下午我会做什么。 过去将来进过去将来完成进行时表示动作从过去某一时间开始一直延续到对于过去来说的将来行时可以表示在过去某一时间之后即将进行的动作。 They said that they could not come for they would be having a group work the next morning. 他们说明天不能来参加活动，因为他们也有个集体活动走不开。

好了的话，现在我们应该在海滩玩了。 解析：这两个过去将来时的例句，都用在虚拟语气中，表示了与过去的事实相反的意义。比如例句1，“要是我们今天下午碰见他，我们就会告诉他整个故事。”那么很显然，这句话表明的意思就是我们没有碰见他，也没有能够告诉他整个故事。所以这个是很值得注意的一点，特别是做翻译的时候。 三、过去将来完成进行时(The past future perfect continuous tense). 而过去将来完成进行时表示从过去某时看至未来某时以前会一直在进行的动作. 由“should/would+ have been +动词现在分词”构成.如： He told me that by the end of the year he would have been living there for thirty years 他告诉我，到年底的时候他就在这儿生活了30年了。 所以，这两个时态在名称上有点拗口，可是表示的意思是很有区过去将来完成时表示在过去将来某一时间以前发生的动作,并往往会对过去将来别的。同学们还要在日常的学习中加以认真分析。

在那所大学教书就满20年了。   三、间接引语与过去将来完成进行时 在间接引语中，若主句为过去时态，则用于宾语从句中的间接引语则要把将来完成进行时改为过去将来完成进行时。如： I know by this time next week you’ll have been working here for 30 years. →I knew by that time he would have been working there for 30 years. She will have been teaching in this university for 20 years by this summer. →She told me she’d have been teaching in that university for 20 years by that summer.   怎么样，看过去将来完成进行完了这篇文章，大家是不是对过去将来完成进行时的用法有了初步的了解了呢？喜欢就赶快收藏起来吧~
