完成時(shí) 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(shí)間的短語連用，而后者常以by開頭： by then到那時(shí) by that time到那時(shí) 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(shí)態(tài)用來表示在將來的一個(gè)特定時(shí)刻將成為過去的動作或在該時(shí)刻剛剛結(jié)束的動作。假設(shè)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(dān)心。 某個(gè)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(shí)大衛(wèi)就考完試了，這樣他就能夠玩得痛快。 同時(shí)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(jìn)行時(shí) 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(shí)一樣，它通常與一個(gè)以by開頭的時(shí)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(dāng)演員就滿30年了。 將來完成進(jìn)行時(shí)與將來完成時(shí)的關(guān)系和現(xiàn)在完成進(jìn)行時(shí)與現(xiàn)在完成時(shí)的關(guān)系一樣。即在以下情況下可以用將來完成進(jìn)行時(shí)而不用將來完成時(shí)： 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

在要重新啟動。 7.During Iteration Planning, the Customer presents the features desired for the next two weeks. 在進(jìn)行迭代計(jì)劃時(shí)，客戶演示下兩周內(nèi)希望完成的特性。 8.Change the following sentences into the Present Continuous Passive Voice. 把下列句子變成現(xiàn)在進(jìn)行時(shí)的被動語態(tài)。 9.`I have finished' is an example of the present perfect. “我已經(jīng)完現(xiàn)在仍在繼續(xù)或剛剛結(jié)束的動作時(shí)，某些動詞既可以用現(xiàn)在完成時(shí)，也可以用現(xiàn)在完成進(jìn)行時(shí)成了”是現(xiàn)在完成時(shí)態(tài)的一個(gè)例句。 10.a perfective tense used to express action completed in the present. 一種用來表達(dá)現(xiàn)在已經(jīng)完成的動作的完成時(shí)態(tài)。 11.And will learn The simple past tense, The present perfect tense, The past perfect tense as well as The future tense. 這個(gè)學(xué)期，我們學(xué)到了過去時(shí)，現(xiàn)在完成時(shí)，過去完成時(shí)和將來時(shí)等。 12.Cleanup of merge meta data cannot be performed while merge processes are running.

行時(shí)主要表示過去某時(shí)的一個(gè)動作正在進(jìn)行。例如： 1. I was writing a letter when she came to see me. 當(dāng)她來看我時(shí)我正在寫信。 2.I had been writing a letter for two hours by the time she came to see me. 當(dāng)她來看我的時(shí)候，我已經(jīng)寫了兩個(gè)小時(shí)的信了。 5. 過去完成進(jìn)完成進(jìn)行時(shí)是一種比較抽象的時(shí)態(tài)，學(xué)習(xí)它需要理解整個(gè)句子所處的語境和時(shí)間。過去完成進(jìn)行時(shí)行時(shí)與過去完成時(shí)的不同。過去完成時(shí)表示過去某時(shí)間前已經(jīng)發(fā)生的動作或情況，這個(gè)過去的時(shí)間可以用by，before等介詞短語或一個(gè)時(shí)間狀語從句來表示；或者表示一個(gè)動作在另一個(gè)過去動作之前已經(jīng)完成。例如： 1. They had just had breakfast when Tom came in. 湯姆來時(shí)，他們剛吃過早飯。 2. They had been having breakfast for ten minutes when Tom came in. 湯姆來時(shí)，他們已經(jīng)吃了十分鐘的早飯了。

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

完成進(jìn)行時(shí)，是英語中，動詞的一種基本時(shí)態(tài)，其構(gòu)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(dá)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(shí)間。 一、將來完成進(jìn)行時(shí)的結(jié)構(gòu) 　　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(gè)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(gè)劇將于8月停演。到那時(shí)為止，這個(gè)劇將連演三個(gè)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(gè)工程上干了7天了。[/cn] ? 二、將來完成進(jìn)行時(shí)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

行時(shí)往往表示動作在重復(fù)，現(xiàn)在完成時(shí)則常常不帶重復(fù)性。如： Have you been meeting her lately？（a） Have you met her lately？（b） （a）句有“經(jīng)常相會”之意，（b）句則沒有。（b）句如與often，every day等時(shí)間狀語連用，當(dāng)然也表示動作在重復(fù)。 （5）現(xiàn)在完成進(jìn)現(xiàn)在完成時(shí)（Present perfect）過去發(fā)生并且已經(jīng)完成的動作對現(xiàn)在造成影響或后果，過去某一時(shí)間開始并一直持續(xù)到現(xiàn)在行時(shí)比較生動，有時(shí)含有明顯的感情色彩，而現(xiàn)在完成時(shí)往往只說明一個(gè)事實(shí)，一種影響或結(jié)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(gè)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(yáng)瑪麗。（b）只說明一個(gè)事實(shí)。 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(qiáng)烈的感情色彩，表示憤怒不滿，（b）句只是希望回答的一個(gè)問題。又，（a）句兼有進(jìn)行時(shí)態(tài)，所以有“蘋果未 被全部吃光”的意思，（b）句是完成時(shí)態(tài)，說明“蘋果一個(gè)不剩了”。?

在有直接影響并且還在進(jìn)行的動作。 例如： He had been waiting for two weeks. He was still waiting.（有一個(gè)表示一段時(shí)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(gè)時(shí)態(tài)并不一定表示這個(gè)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(diǎn)時(shí)她已經(jīng)沒有再等了） 而過去完成時(shí)（The Past Perfect Tense）表示過去某一時(shí)間或動作以前已經(jīng)發(fā)生或完成對過去的某一點(diǎn)造成的某種影響或是結(jié)果。它表示動作發(fā)生的時(shí)間是“過去的過去”，側(cè)重事情的結(jié)果。 例如： I had finished reading the book by ten o'clock last night到昨晚10點(diǎn)鐘，我已經(jīng)讀完成進(jìn)行時(shí)完了這本書。 要想完全掌握這兩種時(shí)態(tài)，需得經(jīng)過大量的練習(xí)，讀完這篇文章，請同學(xué)們趕緊拿起筆來，多多練習(xí)，爭取能正確合理地使用這兩種時(shí)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(jìn)行時(shí)態(tài)。即“The past future perfect continuous tense”.它表示動作從過去某一時(shí)間開始一直延續(xù)到對于過去來說的將來某一時(shí)間，過去將來完成進(jìn)行時(shí)的結(jié)構(gòu)形式如下所示： 由should/would have been + v-ing構(gòu)成其肯定形式； 由should/would+not have been + v-ing構(gòu)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(gè)簡單的栗子，給大家一個(gè)初步的印象。 1、She should have been keeping studying。 她應(yīng)該堅(jiān)持繼續(xù)學(xué)習(xí)。. 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(xué)，到這個(gè)冬天結(jié)束，她就已經(jīng)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(gè)里面，“would have been+現(xiàn)在分詞”結(jié)構(gòu)除用于表示過去將來完成進(jìn)行時(shí)外，有時(shí)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(lǐng)養(yǎng)那些孩子的。 解析：若表示與過去事實(shí)相反的虛擬語氣，此時(shí)條件從句的謂語用過去完成時(shí)(had+過去分詞)，而主句謂語則通常用過去完成時(shí)（would+have+過去分詞），當(dāng)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(jìn)行時(shí)和將來完成時(shí)的區(qū)別 將來完成時(shí)的結(jié)構(gòu)是：will+have+過去分詞；而將來完成進(jìn)行時(shí)的結(jié)構(gòu)是：will+have+been+現(xiàn)在行時(shí)強(qiáng)調(diào)動作過程在另一動詞之前的長度。而將來完成時(shí)更強(qiáng)調(diào)在另一件事前一個(gè)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(shí)候，詹姆斯已經(jīng)在從事工作10年了。[/cn] 與這個(gè)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(jīng)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(xué)習(xí)就滿十年了。[/cn] 與這個(gè)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(gè)月底，他就已經(jīng)工作了
