完成时 形式 will/shall+完成式用于第一人称，will+完成式用于其他人称。 用法 它常与表示时间的短语连用，而后者常以by开头： by then到那时 by that time到那时 by the 24th到 24号那天 By the end of next month he will have been here for ten years． 到下月底，他在这儿就够十年了。 这一时态用来表示在将来的一个特定时刻将成为过去的动作或在该时刻刚刚结束的动作。假设现在是12月3日，大卫对他将参加的12月13日的考试很担心。 某个筹划举办聚会的人可能说： We’d better wait till 14 December．David will have had his exam by then， so he’ll be able to enjoy himself． 我们最好还是等到12月14日。到那时大卫就考完试了，这样他就能够玩得痛快。 同时请注意以下句子： I save￡ 50 a month and I started in January．So by the end of the year I will/shall have saved￡ 600． 我每月储蓄50英镑，是从1月份开始的。这样的话，到年底我就有600英镑的存款了。 Bill（looking at Tom’s cellar）：You’ve got over 400 bottles．How long will that last you？Two years？ 比尔（瞧着汤姆的地下室）：你有四百多瓶酒。够你喝多久？两年？ Tom：Not a hope．I drink eight bottles a week．I’ll have drunk all these by the end of this year． 汤姆：不可能。我每星期喝八瓶。到今年年底我就会把所有这些酒都喝完了。 将来完成进行时 形式 will/shall have been+现在分词用于第一人称，而 will have been+现在分词用于其他人称。 用法 正如将来完成时一样，它通常与一个以by开头的时间短语连用： By the end of this year he’ll have been acting for thirty years． 到今年年底他当演员就满30年了。 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

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。

完成进行时，是英语中，动词的一种基本时态，其构成为：主语+shall/will+助动词have+been+动词的现在分词+其他成分。其表达的意思为：表示某种情况下一直持续到说话人所提及的时间。 一、将来完成进行时的结构 　　主语+ shall/will + have + been + 现在分词 + 其他成分 　　如: 　　1.I shall have been working here in this factory for twenty years by the end of the year. [cn]到今 年年底，我将在这个工厂工作20年了[/cn] 　　2.The play is coming off in August. By then the play will have been running for three months. [cn]这个剧将于8月停演。到那时为止，这个剧将连演三个月了。[/cn] 　　3.By Friday midday, they will have been working on it for seven days.[cn]到星期五中午，他们就在这个工程上干了7天了。[/cn]   二、将来完成进行时的用法 　　在下列句子中，will是情态助动词，有“大概”或“我想”的含义。 　　如： 　　1.You’ll have been

行时往往表示动作在重复，现在完成时则常常不带重复性。如： Have you been meeting her lately？（a） Have you met her lately？（b） （a）句有“经常相会”之意，（b）句则没有。（b）句如与often，every day等时间状语连用，当然也表示动作在重复。 （5）现在完成进现在完成时（Present perfect）过去发生并且已经完成的动作对现在造成影响或后果，过去某一时间开始并一直持续到现在行时比较生动，有时含有明显的感情色彩，而现在完成时往往只说明一个事实，一种影响或结果，平铺直 叙，没有什么感情色彩可言。如： What have you been doing？（a） What have you done？（b） （a）句表示惊异。（b）句只是一个问题。 Have you been waiting long？（a） Have you waited long？（b） （a）句较（b）句生动。又，（a）句比较口语化。 I have been wanting to meet you for long．（a） I have long wanted to meet you．（b） （a）句比（b）句更亲切，更有礼貌。 Recently Mary has been doing her work regularly．（a） Recently Mary has done her work regularly．（b） （a）句显然是在表扬玛丽。（b）只说明一个事实。 下面还有一例，颇为有趣: Who's been eating my apples？（a） Who's eaten my apples？（b） （a）句有强烈的感情色彩，表示愤怒不满，（b）句只是希望回答的一个问题。又，（a）句兼有进行时态，所以有“苹果未 被全部吃光”的意思，（b）句是完成时态，说明“苹果一个不剩了”。 

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完成进行时态。即“The past future perfect continuous tense”.它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某一时间，过去将来完成进行时的结构形式如下所示： 由should/would have been + v-ing构成其肯定形式； 由should/would+not have been + v-ing构成否定形式； 将should/would提前作为其疑问形式。 具体的用法，先给大家举几个简单的栗子，给大家一个初步的印象。 1、She should have been keeping studying。 她应该坚持继续学习。. 2、She  told her classmates that by the end of this winter  she would have been living there for 12years. 她告诉她的同学，到这个冬天结束，她就已经在那儿生活了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”。

完成进行时和将来完成时的区别 将来完成时的结构是：will+have+过去分词；而将来完成进行时的结构是：will+have+been+现在行时强调动作过程在另一动词之前的长度。而将来完成时更强调在另一件事前一个动作的完成。 　　如： 　　By the time John retires, James will have been practicing for 10 years. [cn]到约翰退休的时候，詹姆斯已经在从事工作10年了。[/cn] 与这个句子有所区别：       Before the time John retires, James would have retired. [cn]在约翰退休前，詹姆斯就已经退休了。[/cn] 　　2、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. [cn]到了月底他在这里居住/工作/学习就满十年了。[/cn] 与这个句子有所区别：      By the end of the month, he will have worked for ten years. [cn]到了这个月底，他就已经工作了

在有直接影响并且还在进行的动作。 例如： He had been waiting for two weeks. He was still waiting.（有一个表示一段时间的状语） She had been suffering from a bad cold when she took the exam.她在考试之前一直患重感冒。 不过这个时态并不一定表示这个过去动作将持续下去： 例如： She came back at six. She had been waiting for him three hours.（六点时她已经没有再等了） 而过去完成时（The Past Perfect Tense）表示过去某一时间或动作以前已经发生或完成对过去的某一点造成的某种影响或是结果。它表示动作发生的时间是“过去的过去”，侧重事情的结果。 例如： I had finished reading the book by ten o'clock last night到昨晚10点钟，我已经读完成进行时完了这本书。 要想完全掌握这两种时态，需得经过大量的练习，读完这篇文章，请同学们赶紧拿起笔来，多多练习，争取能正确合理地使用这两种时态！

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
