本書就已經(jīng)被讀了兩周了。 8. She told me she would have been teaching in that university for 20 years by that summer. 她告訴我到那年夏天她完成進(jìn)行時(shí)和過去將來完成時(shí)，還特地把過去將來完成時(shí)在那所大學(xué)教書就滿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，我會(huì)忘了我媽媽的生日。 10. She would have been travelling for two weeks. 她已經(jīng)旅游2周了。

行時(shí)：They have been reading books for two weeks. 將來完成進(jìn)行時(shí)：They will have been reading books for two weeks. （4） 過去將來完成進(jìn)行時(shí)：She would have been thinking about it by the end of the year. 現(xiàn)在完成進(jìn)完成進(jìn)行時(shí)、現(xiàn)在和將來完成進(jìn)行時(shí)的區(qū)別。主要是得分清所說事件發(fā)生在何時(shí)。今天我們來做些練習(xí)行時(shí)：She has been thinking about it by the end of the year. 將來完成進(jìn)行時(shí)：She will have been thinking about it by the end of the year. 本篇的練習(xí)到此為止，同學(xué)們都記清三個(gè)時(shí)態(tài)的用法了嗎？

國有2000年的造紙歷史。[/cn] （動(dòng)作還將繼續(xù)下去） [en]I have been learning English since three years ago.[/en][cn]自從三年前以來我一直在學(xué)英語。[/cn] （動(dòng)作還將繼續(xù)下去） 4、大多數(shù)現(xiàn)在完成進(jìn)行時(shí)的句子不等同于現(xiàn)在完成時(shí)的句子。 [en]I have been writing a book.[/en][cn]我一直在寫一本書。[/cn] （動(dòng)作還將繼續(xù)下去） [en]I have written a book.[/en][cn]我已經(jīng)寫了一本書。[/cn] （動(dòng)作已經(jīng)完成） 5、表示狀態(tài)的動(dòng)詞不能用于現(xiàn)在完成進(jìn)現(xiàn)在完成進(jìn)行時(shí)的結(jié)構(gòu)：助動(dòng)詞have(has) + been+動(dòng)詞的現(xiàn)在分詞。表示動(dòng)作從某一時(shí)間開始，一直持續(xù)到現(xiàn)在行時(shí)。 [en]I have known him for years.[/en][cn]我認(rèn)識(shí)他已經(jīng)好幾年了。[/cn] 這類不能用于現(xiàn)在完成進(jìn)行時(shí)的動(dòng)詞還有：love，like，hate等。

行時(shí)：表示將來的某個(gè)時(shí)間要發(fā)生的動(dòng)作。經(jīng)常用來表示詢問、請(qǐng)求等?；窘Y(jié)構(gòu)：主語+shall/will+be+現(xiàn)在分詞+ 其它。 8.過去和將來進(jìn)行時(shí)：表示就過去某一時(shí)間而言，將來某一時(shí)刻或某一段時(shí)間正在進(jìn)行的動(dòng)作。常用于賓語從句，尤其是間接引語中?；窘Y(jié)構(gòu)：Should /would+be+現(xiàn)在分詞。 9.現(xiàn)在完成時(shí)：過去發(fā)生或完成的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果，或從過去開始并持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)?；窘Y(jié)構(gòu)：主語+have/has+過去分詞+其他。 10. 過去完成時(shí)：基于過去的某個(gè)時(shí)間，在此以前發(fā)生的動(dòng)作或行為，或在過去某動(dòng)作之前完成的行為?；窘Y(jié)構(gòu)：主語+had+過去分詞+其它。 以上就是英語語法學(xué)習(xí)內(nèi)容的分享，希望可以給大家學(xué)習(xí)帶來幫助。 如果您對(duì)英語學(xué)習(xí)感興趣，想要深入學(xué)習(xí)，可以了解滬江網(wǎng)校精品課程，量身定制高效實(shí)用的個(gè)性化學(xué)習(xí)方案，專屬督導(dǎo)全程伴學(xué)。掃一掃領(lǐng)200暢學(xué)卡

行時(shí)由have/has been + -ing分詞構(gòu)成。它的主要用法與現(xiàn)在完成時(shí)的“未完成”用法相仿。 例如： I have been writing letters for an hour ( and I’ve still got some to do ). I have been sitting in the garden ( and have just come indoors ). I have been doing the same job in another company. 我一直在另一家公司里做同樣的工作. I have been doing breathing exercises to replenish my energy. ?這幾天在家養(yǎng)氣呢,補(bǔ)充精力. 上述第一例說明動(dòng)作還將繼續(xù)下去，第二例說明動(dòng)作在說話之前剛剛結(jié)束。 現(xiàn)在完成時(shí)和現(xiàn)在完成進(jìn)行時(shí)有時(shí)可以互換使用，含義沒有太多明顯差別。 例如： We have been living here for ten years. We have lived here for ten years. 但是，由于現(xiàn)在完成進(jìn)現(xiàn)在完成進(jìn)行時(shí)的用法相較于現(xiàn)在完成時(shí)要稍微簡(jiǎn)單一點(diǎn)，有時(shí)可以兩者互換 但是，同學(xué)們?cè)谑褂矛F(xiàn)在完成進(jìn)行時(shí)行時(shí)還帶有進(jìn)行時(shí)

過去完成時(shí) 1.概念：以過去某個(gè)時(shí)間為標(biāo)準(zhǔn)，在此以前發(fā)生的動(dòng)作或行為，或在過去某動(dòng)作之前完成的行為，即“過去的過去”。 2.時(shí)間狀語：Before, by the end of last year (term, month…), etc. 3.基本結(jié)構(gòu)：主語+had + p.p（過去分詞）+其他 4.否定形式：主語+had + not +p.p（過去分詞）+其他 5.一般疑問句：had放于句首。 6.例句：As soon as we got to the station,the train had left.

完成時(shí)和過去完成時(shí)在動(dòng)作完成的程度上是一致的，都表示過去某段時(shí)間已經(jīng)完成的事情或者完成的一種狀態(tài)，只是，過去將來完成時(shí)長城。 4.By the end of the match, they had kicked 2 goals, and we had kicked 4.比賽結(jié)束時(shí)，他們踢進(jìn)了2個(gè)球而我們踢進(jìn)了4個(gè)球。 5.When Jack arrived he learned Mary had been away for almost an hour. 杰克到達(dá)后得知瑪麗走了近一個(gè)小時(shí)了。 6.The news came as no surprise to me. I had known for some time that the factory was going to shut down. 聽到這個(gè)消息我并不感到吃驚。工廠要倒閉這件事我早就知道了。 7.By the time I left the school, he had taught

別的含義： 1)尚未完成： He had been writing the novel.(He had not finished it yet.) 2)企圖： He had been studying the meaning of this proverb.(He was trying to study it.) 3)未得結(jié)果： We had been studying what our enemy had said.(But we were not able to understand it.) 4)最近情況： He had been quarrelling with his wife.(lately) 5)反復(fù)動(dòng)作： He had been asking me the same question.(Many times) 6)情緒： What had he been doing?(不耐煩) 這個(gè)時(shí)態(tài)很少用在否定句中，而多以過去完成時(shí)代替： He had not practised English for many years.(普通說法) He had not been practising English for many years.(少見) 這個(gè)時(shí)態(tài)還可用在said，supposed等引起的間接引語中，代替現(xiàn)在完成進(jìn)完成進(jìn)行時(shí)與過去完成時(shí)行時(shí)： 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. ? 聲明：滬江網(wǎng)高度重視知識(shí)產(chǎn)權(quán)保護(hù)，發(fā)現(xiàn)本網(wǎng)站發(fā)布的信息包含有侵犯其著作權(quán)的鏈接內(nèi)容時(shí)，請(qǐng)聯(lián)系我們，我們將做相應(yīng)處理。

面的句子試比較： It had rained yesterday. (誤) It rained yesterday.(正) ? 或許你會(huì)說：“昨天下了雨，可是今天已放晴了，下雨已是過去的事，而且已經(jīng)下完了，所以就用過去完成時(shí)……?！边@就是最令同學(xué)們對(duì)一般過去時(shí)和過去完成時(shí)感到混淆和困惑的。實(shí)際上只要我們了解下面的兩點(diǎn)原則就可以消除這種現(xiàn)象。 1. 由過去的時(shí)間作狀語來修飾動(dòng)詞的句子都完成時(shí)表示表示過去的過去。這個(gè)是大家在中學(xué)時(shí)期就知道的，今天，小編為同學(xué)們帶來了相當(dāng)豐富的與英語過去完成時(shí)使用一般過去時(shí)。 2. 除非從談話的先后關(guān)系和上下文關(guān)系對(duì)過去的動(dòng)作完成的基準(zhǔn)點(diǎn)可以確定以外，應(yīng)該避免在簡(jiǎn)單句中使用過去完成時(shí)。 ? 怎么樣，看完了小編給大家準(zhǔn)備的語法知識(shí)，有沒有感覺收獲頗多呢？喜歡就收藏起來吧~

完成時(shí)兒時(shí)，我們已經(jīng)把房子弄干凈了。 注意：當(dāng)主句跟由before, after, as soon as所引導(dǎo)的時(shí)間從句的動(dòng)作連接很緊密時(shí)，從句也可用一般過去時(shí)。 He went there after he read the letter. 他看了那封信后就去那兒了。 2、在hardly / scarcely …when…, no sooner…than… 兩個(gè)結(jié)構(gòu)中的主句通常要用過去完成時(shí)。如： Hardly had I told her the news when she began to cry out. 她一聽到這一消息就大哭了起來。 No sooner had he fallen asleep than he lay down on the bed. 他一躺倒床上就睡著了。 3、動(dòng)詞expect, hope, suppose, think, want等的過去完成時(shí)可用來表示未實(shí)現(xiàn)的計(jì)劃、打算或希望。如： He had wanted to buy a house in Shanghai. 他本想在上海買棟房子。 4、過去完成時(shí)還經(jīng)常用于主句為過去時(shí)的賓語從句中。如： They said they had seen the film. 他們說這個(gè)電影他們看過。 以上就是過去完成時(shí)的定義和基本用法，總之，要學(xué)好過去完成時(shí)，還應(yīng)多練習(xí)，多讀英語文章，培養(yǎng)語感，總結(jié)經(jīng)驗(yàn)，久而久之，句子使用的準(zhǔn)確性就會(huì)不知不覺提高很多。所以，同學(xué)們要勤奮起來哦，為今后的英語學(xué)習(xí)打下基礎(chǔ)。
