行時的相關語法，一起來看看吧！ ? 過去完成進行式（Past Perfect Progressive Tense） 如果我們要強調較早發(fā)生事件的連續(xù)性，我們可以用過去完成進行式。占去完成進行式和現(xiàn)在進行式惟一不同的地方是 verb to have 的地方一定要用had 。 以下是一些過去完成進行式的例子： 1.

完成時 形式 will/shall+完成式用于第一人稱，will+完成式用于其他人稱。 用法 它常與表示時間的短語連用，而后者常以by開頭： by then到那時 by that time到那時 by the 24th到 24號那天 By the end of next month he will have been here for ten years． 到下月底，他在這兒就夠十年了。 這一時態(tài)用來表示在將來的一個特定時刻將成為過去的動作或在該時刻剛剛結束的動作。假設現(xiàn)在是12月3日，大衛(wèi)對他將參加的12月13日的考試很擔心。 某個籌劃舉辦聚會的人可能說： We’d better wait till 14 December．David will have had his exam by then， so he’ll be able to enjoy himself． 我們最好還是等到12月14日。到那時大衛(wèi)就考完試了，這樣他就能夠玩得痛快。 同時請注意以下句子： I save￡ 50 a month and I started in January．So by the end of the year I will/shall have saved￡ 600． 我每月儲蓄50英鎊，是從1月份開始的。這樣的話，到年底我就有600英鎊的存款了。 Bill（looking at Tom’s cellar）：You’ve got over 400 bottles．How long will that last you？Two years？ 比爾（瞧著湯姆的地下室）：你有四百多瓶酒。夠你喝多久？兩年？ Tom：Not a hope．I drink eight bottles a week．I’ll have drunk all these by the end of this year． 湯姆：不可能。我每星期喝八瓶。到今年年底我就會把所有這些酒都喝完了。 將來完成進行時 形式 will/shall have been+現(xiàn)在分詞用于第一人稱，而 will have been+現(xiàn)在分詞用于其他人稱。 用法 正如將來完成時一樣，它通常與一個以by開頭的時間短語連用： By the end of this year he’ll have been acting for thirty years． 到今年年底他當演員就滿30年了。 將來完成進行時與將來完成時的關系和現(xiàn)在完成進行時與現(xiàn)在完成時的關系一樣。即在以下情況下可以用將來完成進行時而不用將來完成時： 1 動作本身就是連續(xù)的： By the end of the month he will have been living/working/studying here for ten years． 到了月底他在這里居住

行時主要表示過去某時的一個動作正在進行。例如： 1. I was writing a letter when she came to see me. 當她來看我時我正在寫信。 2.I had been writing a letter for two hours by the time she came to see me. 當她來看我的時候，我已經寫了兩個小時的信了。 5. 過去完成進完成進行時是一種比較抽象的時態(tài)，學習它需要理解整個句子所處的語境和時間。過去完成進行時行時與過去完成時的不同。過去完成時表示過去某時間前已經發(fā)生的動作或情況，這個過去的時間可以用by，before等介詞短語或一個時間狀語從句來表示；或者表示一個動作在另一個過去動作之前已經完成。例如： 1. They had just had breakfast when Tom came in. 湯姆來時，他們剛吃過早飯。 2. They had been having breakfast for ten minutes when Tom came in. 湯姆來時，他們已經吃了十分鐘的早飯了。

完成進行時，是英語中，動詞的一種基本時態(tài)，其構成為：主語+shall/will+助動詞have+been+動詞的現(xiàn)在分詞+其他成分。其表達的意思為：表示某種情況下一直持續(xù)到說話人所提及的時間。 一、將來完成進行時的結構 　　主語+ shall/will + have + been + 現(xiàn)在分詞 + 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，我將在這個工廠工作20年了[/cn] 　　2.The play is coming off in August. By then the play will have been running for three months. [cn]這個劇將于8月停演。到那時為止，這個劇將連演三個月了。[/cn] 　　3.By Friday midday, they will have been working on it for seven days.[cn]到星期五中午，他們就在這個工程上干了7天了。[/cn] ? 二、將來完成進行時的用法 　　在下列句子中，will是情態(tài)助動詞，有“大概”或“我想”的含義。 　　如： 　　1.You’ll have been

能與表示確定的過去時間狀語連用?，F(xiàn)在完成時要求用for和。i。引導包括現(xiàn)在此時在內的時間狀語以及already, yet, ever等表示強調的副詞。一般過去時態(tài)要求用yesterday, last year, in 1990, an hour ago等不包括現(xiàn)在在內的具體的過去時間狀語。但有時for+一時間段”也可用于一般過去時，雖然時問狀語相同，但具體含義不同。 We have studied English for 5 years. 我已學習5年英語了。(直到現(xiàn)在的5年) We studied English for 5 years. 我曾學過5年英語。(與現(xiàn)在無關的5年) 2) today, this month, this year, recently, just, always等既可用于現(xiàn)在完成時，t可用于一般過去時，但其

行時往往表示動作在重復，現(xiàn)在完成時則常常不帶重復性。如： Have you been meeting her lately？（a） Have you met her lately？（b） （a）句有“經常相會”之意，（b）句則沒有。（b）句如與often，every day等時間狀語連用，當然也表示動作在重復。 （5）現(xiàn)在完成進現(xiàn)在完成時（Present perfect）過去發(fā)生并且已經完成的動作對現(xiàn)在造成影響或后果，過去某一時間開始并一直持續(xù)到現(xiàn)在行時比較生動，有時含有明顯的感情色彩，而現(xiàn)在完成時往往只說明一個事實，一種影響或結果，平鋪直 敘，沒有什么感情色彩可言。如： What have you been doing？（a） What have you done？（b） （a）句表示驚異。（b）句只是一個問題。 Have you been waiting long？（a） Have you waited long？（b） （a）句較（b）句生動。又，（a）句比較口語化。 I have been wanting to meet you for long．（a） I have long wanted to meet you．（b） （a）句比（b）句更親切，更有禮貌。 Recently Mary has been doing her work regularly．（a） Recently Mary has done her work regularly．（b） （a）句顯然是在表揚瑪麗。（b）只說明一個事實。 下面還有一例，頗為有趣: Who's been eating my apples？（a） Who's eaten my apples？（b） （a）句有強烈的感情色彩，表示憤怒不滿，（b）句只是希望回答的一個問題。又，（a）句兼有進行時態(tài)，所以有“蘋果未 被全部吃光”的意思，（b）句是完成時態(tài)，說明“蘋果一個不剩了”。?

在有直接影響并且還在進行的動作。 例如： He had been waiting for two weeks. He was still waiting.（有一個表示一段時間的狀語） She had been suffering from a bad cold when she took the exam.她在考試之前一直患重感冒。 不過這個時態(tài)并不一定表示這個過去動作將持續(xù)下去： 例如： She came back at six. She had been waiting for him three hours.（六點時她已經沒有再等了） 而過去完成時（The Past Perfect Tense）表示過去某一時間或動作以前已經發(fā)生或完成對過去的某一點造成的某種影響或是結果。它表示動作發(fā)生的時間是“過去的過去”，側重事情的結果。 例如： I had finished reading the book by ten o'clock last night到昨晚10點鐘，我已經讀完成進行時完了這本書。 要想完全掌握這兩種時態(tài)，需得經過大量的練習，讀完這篇文章，請同學們趕緊拿起筆來，多多練習，爭取能正確合理地使用這兩種時態(tài)！

活了12年了。 3、I heard by July you’d have been teaching here for ten years.?? 我聽說到七月份，你就在這里教了10年書了。 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?”海倫向他問道。他知道海倫一定會一直想這完成進行時態(tài)。即“The past future perfect continuous tense”.它表示動作從過去某一時間開始一直延續(xù)到對于過去來說的將來某一時間，過去將來完成進行時的結構形式如下所示： 由should/would have been + v-ing構成其肯定形式； 由should/would+not have been + v-ing構成否定形式； 將should/would提前作為其疑問形式。 具體的用法，先給大家舉幾個簡單的栗子，給大家一個初步的印象。 1、She should have been keeping studying。 她應該堅持繼續(xù)學習。. 2、She ?told her classmates that by the end of this winter ?she would have been living there for 12years. 她告訴她的同學，到這個冬天結束，她就已經在那兒生活了12年了。 3、I heard by July you’d have been teaching here for ten years.?? 我聽說到七月份，你就在這里教了10年書了。 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?”海倫向他問道。他知道海倫一定會一直想這件事的。 ?解析：這個里面，“would have been+現(xiàn)在分詞”結構除用于表示過去將來完成進行時外，有時其中的?would?也可能是情態(tài)動詞，具有情態(tài)意義，比較表示推測或猜想等。 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，我是決不會讓他領養(yǎng)那些孩子的。 解析：若表示與過去事實相反的虛擬語氣，此時條件從句的謂語用過去完成時(had+過去分詞)，而主句謂語則通常用過去完成時（would+have+過去分詞），當然，主句謂語也可根據(jù)情況使用“should (could, might)+have+過去分詞”。

完成進行時和將來完成時的區(qū)別 將來完成時的結構是：will+have+過去分詞；而將來完成進行時的結構是：will+have+been+現(xiàn)在行時強調動作過程在另一動詞之前的長度。而將來完成時更強調在另一件事前一個動作的完成。 　　如： 　　By the time John retires, James will have been practicing for 10 years. [cn]到約翰退休的時候，詹姆斯已經在從事工作10年了。[/cn] 與這個句子有所區(qū)別： ? ? ? Before the time John retires, James would have retired. [cn]在約翰退休前，詹姆斯就已經退休了。[/cn] 　　2、動作本身就是連續(xù)的： 　　By the end of the month he will have been living/working/studying here for ten years. [cn]到了月底他在這里居住/工作/學習就滿十年了。[/cn] 與這個句子有所區(qū)別： ? ? ?By the end of the month, he will have worked for ten years. [cn]到了這個月底，他就已經工作了
