行时。如： I’ll have finished in the bathroom in a few minutes. 我一会儿就用完浴室了。 As soon as I have finished I’ll give you a call. 我一完事儿，就给你打电话。   三、将来完成进行时与将来完成时比较 将来完成进行时与将来完成时的关系和现在完成进行时与现在完成时的关系一样。即在以下情况下可以用将来完成进行时而不用将来完成时： 1. 动作本身就是连续的： By the end of the month he will have been living / working / studying here for ten years. 到了月底他在这里居住 / 工作 / 学习就满十年了。 2. 一种经常进行的动作被表示为连续的动作： By the end of this month he will have been training horses / climbing mountains for twenty years. 到了这个月底他驯马 / 登山就满 20年了。 但是如果提到所驯马匹或所攀登的山峰的数目，或用任何方式把动作分割为一次又一次的动作，就必须用将来完成时： By the end of the month he will have trained 600 horses / climbed 50 mountains. 到本月底，他驯服的马就有600匹 / 攀登的山峰就有50座了。   怎么样，看完成进行时是英语时态中比较常见的一种，但是，大家对它的用法可能还是不太了解。今天，小编为大家准备了相关的语法知识，将要为大家来讲解一下：将来完成进行时的概念和用法，一起来看看吧！   一、将来完成进行时的情态意义 “will / shall have been+现在分词”结构除表示将来完成进行时外，有时其中的 will 也可能是情态动词，具有情态意义，比较表示推测或猜想等。如： They will have been having a holiday yesterday. 他们昨天大概是在度假。 You’ll have been wondering all this time how my invention works. 我想你这些时候一直想知道我的发明怎样会行得通的。   二、将来完成进行时用于状语从句的变体 正如我们通常要在条件状语从句和时时间状语从句中用一般现在时代替一般将来时以及用现在完成时代替将来完成时等一样，如果因语义的需要，我们需要在条件状语从句和时时间状语从句中使用将来完成进行时，那么我们通常要用现在完成进行时代替将来完成进行时。如： I’ll have finished in the bathroom in a few minutes. 我一会儿就用完浴室了。 As soon as I have finished I’ll give you a call. 我一完事儿，就给你打电话。   三、将来完成进行时与将来完成时比较 将来完成进行时与将来完成时的关系和现在完成进行时与现在完成时的关系一样。即在以下情况下可以用将来完成进行时而不用将来完成时： 1. 动作本身就是连续的： By the end of the month he will have been living / working / studying here for ten years. 到了月底他在这里居住 / 工作 / 学习就满十年了。 2. 一种经常进行的动作被表示为连续的动作： By the end of this month he will have been training horses / climbing mountains for twenty years. 到了这个月底他驯马 / 登山就满 20年了。 但是如果提到所驯马匹或所攀登的山峰的数目，或用任何方式把动作分割为一次又一次的动作，就必须用将来完成时： By the end of the month he will have trained 600 horses / climbed 50 mountains. 到本月底，他驯服的马就有600匹 / 攀登的山峰就有50座了。   怎么样，看完了这篇文章，大家是不是对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~

别的含义： 1）尚未完成： He had been writing the novel．（He had not finished it yet．） 2）企图： He had been studying the meaning of this proverb．（He was trying to study it．） 3）未得结果： We had been studying what our enemy had said．（But we were not able to understand it．） 4）最近情况： He had been quarrelling with his wife．（lately） 5）反复动作： He had been asking me the same question．（Many times） 6）情绪： What had he been doing？（不耐烦） 这个时态很少用在否定句中，而多以过去完成时代替： He had not practised English for many years．（普通说法） He had not been practising English for many years．（少见） 这个时态还可用在said，supposed等引起的间接引语中，代替现在完成进完成进行时行时： He said，“I have been speaking to John．”＝ He said that he had been speaking to John． He thought，“She was watching me when I passed．”＝ He thought that she had been watching him when he had passed．    怎么样，看完了小编给大家准备的语法知识，有没有感觉收获颇多呢？喜欢就收藏起来吧~

完成进行时的形式： I（or You，He，John，They，Those men）will have been doing it 例：I shall have been doing it．  将来完成进行时的用法和将来完成时的用法很相近，主要是将来完成进行时已在发生的动作： He will have been playing on the piano by that time． 他在那个时候之前应该一直都在弹钢琴。 2）表示将来某时某动作已持续多久： By the time the sun rises, I shall have been sleeping for nine hours. 太阳升起来之前，我已经（不停地）睡了9个小时了。 He will have been studying Chinese seven years by 1980. 到1980年之前，他就已经学了7年中文了。 By six this evening I shall have been working for ten hours. 今天傍晚六点前，我就已经（连续）工作了10个小时了。 It will have been raining for a whole week if it rains again

能与表示确定的过去时间状语连用。现在完成时要求用for和。i。引导包括现在此时在内的时间状语以及already, yet, ever等表示强调的副词。一般过去时态要求用yesterday, last year, in 1990, an hour ago等不包括现在在内的具体的过去时间状语。但有时for+一时间段”也可用于一般过去时，虽然时问状语相同，但具体含义不同。 We have studied English for 5 years. 我已学习5年英语了。(直到现在的5年) We studied English for 5 years. 我曾学过5年英语。(与现在无关的5年) 2) today, this month, this year, recently, just, always等既可用于现在完成时，t可用于一般过去时，但其

行时的用法 A. 在某段时间内一直进行的动作用现在完成进行时来强调动作在某段时间里的持续性动作通常有"现在"的结果要根据上下文来确定到"现在"为止动作是否还在继续进行同样过去完成进行时表示在过去更早时间内进行的动作,并对过去某一时刻产生结果。 B.表示重复动作的现在/过去完成进行时 我们也可以用完成进完成时代替，例如： He had not practiced English for many years 他没有练习英语很多年了。（普通说法） He had not been practicing English for many years. 很多年了，他一直没有练习英语。（少见） 二、这种时态还可用在said，supposed等引起的间接引语中代替现在完成进行时 He said“I have been speaking to John”= He said that he had been speaking to John 他说“我一直和约翰说着话”。 He thought“She was watching me when I passed”= He thought that she had been watching him when he had passed 他想“当我经过的时候，她正看着我”。 三、过去完成进行时经常与现在完成进行时混淆。 现在完成进行时 (The present perfect progressive) 由 have/has been +-分词构成 过去完成进行时 The past perfect progressive tenses 由 had been +-分词构成 四、现在/过去完成进行时的用法 A. 在某段时间内一直进行的动作用现在完成进行时来强调动作在某段时间里的持续性动作通常有"现在"的结果要根据上下文来确定到"现在"为止动作是否还在继续进行同样过去完成进行时表示在过去更早时间内进行的动作,并对过去某一时刻产生结果。 B.表示重复动作的现在/过去完成进行时 我们也可以用完成进行时形式来表示现在或过去经常重复的动作。 注意过去完成进行时和过去完成时类似需要有过去这一时间点。

行时主要表示过去某时的一个动作正在进行。例如： 1. I was writing a letter when she came to see me. 当她来看我时我正在写信。 2.I had been writing a letter for two hours by the time she came to see me. 当她来看我的时候，我已经写了两个小时的信了。 5. 过去完成进完成进行时是一种比较抽象的时态，学习它需要理解整个句子所处的语境和时间。过去完成进行时行时与过去完成时的不同。过去完成时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. They had just had breakfast when Tom came in. 汤姆来时，他们刚吃过早饭。 2. They had been having breakfast for ten minutes when Tom came in. 汤姆来时，他们已经吃了十分钟的早饭了。
