過(guò)去完成時(shí)既可表示過(guò)去某個(gè)時(shí)間或動(dòng)作之前所發(fā)生的事情，也可表示過(guò)去來(lái)看例句； 例如： 1.They had never seen so many of the locusts before. 他們以前從未見(jiàn)過(guò)如此多的蝗蟲(chóng) 2.I had reached the station before six o'clock. 六點(diǎn)之前我已到達(dá)車(chē)站。 好了，通過(guò)以上的幾個(gè)例句，大家是否了解了英語(yǔ)過(guò)去完成時(shí)中表主句（had done）, before + 過(guò)去時(shí)間狀語(yǔ)的情況呢？ 那么，接下來(lái)我們做幾道關(guān)于英語(yǔ)過(guò)去完成時(shí)的練習(xí)題： 1．He asked me _____ during the summer holidays. A. where I had been ?B. where I had gone ?? C. where had I been ? D. where had I gone? 2. What ___ Jane ____ by the time he was sever? A. did, do ? B.

行時(shí)。[/cn]? I realised I had been working too hard so I decided to have a holiday. ? By the time Jane arrived we had been waiting for 3 hours. [en]NOTE[/en][cn]備注[/cn] [en]The most common mistake with the past perfect is to overuse it or to use it simply because we are talking about a time in the distant past.[/en][cn] 最常見(jiàn)的過(guò)度使用過(guò)去完成時(shí)的錯(cuò)誤，就是僅僅是用它形容遙遠(yuǎn)的過(guò)去的時(shí)間。[/cn]? The Romans had spoken Latin[en]Remember that we only use the past perfect when we want to refer to a past that is earlier than another time in the narrative.[/en][cn]請(qǐng)記住，我們用過(guò)去過(guò)去完成時(shí)只是用它來(lái)特指一個(gè)早于敘述的過(guò)去某時(shí)間的時(shí)間。[/cn]

面的句子試比較： It had rained yesterday. (誤) It rained yesterday.(正) 或許你會(huì)說(shuō)：“昨天下了雨，可是今天已放晴了，下雨已是過(guò)去的事，而且已經(jīng)下完了，所以就用過(guò)去完成時(shí)……?！边@就是最令同學(xué)們對(duì)一般過(guò)去時(shí)和過(guò)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(guò)去的時(shí)過(guò)去完成時(shí)(The Past Perfect Tense)：表示過(guò)去某一時(shí)間或動(dòng)作以前已經(jīng)發(fā)生或完成了的動(dòng)作，對(duì)過(guò)去的某一點(diǎn)造成間作狀語(yǔ)來(lái)修飾動(dòng)詞的句子都使用一般過(guò)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(guò)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(guò)去完成時(shí)。 ?

過(guò)去完成時(shí)表示"原本…，未能…" 　　 We had hoped that you would come, but you didn't. 3)　過(guò)去完成時(shí)的時(shí)間狀語(yǔ)before, by, until , when, after, once, as soon as。 　 He said that he had learned some English before. 　 By the time he was twelve, Edison had began to make a living by himself. 　Tom was disappointed that most of the guests had left when he arrived at the party. 典型例題　 　 The students ___ busily when Miss Brown went to get a book she ___ in the office.　 A. had written, left　B，were writing, has left　 C. had written, had left　D. were writing, had left 　 答案D. "把書(shū)忘在辦公室"發(fā)生在"去取書(shū)"這一過(guò)去的動(dòng)作之前，因此"忘了書(shū)"這一動(dòng)作發(fā)生在過(guò)去的過(guò)去，用過(guò)去完成時(shí) ? 1） 概念：表示過(guò)去的過(guò)去 ----|-------|-----|---->其構(gòu)成是had +過(guò)去分詞構(gòu)成過(guò)去完成時(shí)。句中when表示的是時(shí)間的一點(diǎn)，表示在"同學(xué)們正忙于……"這一背景下，when所引導(dǎo)的動(dòng)作發(fā)生。因此 前一句應(yīng)用過(guò)去進(jìn)行時(shí)。 注意：　had no … when　　　　　還沒(méi)等…… 就…… 　　　　had no sooner… than　　剛…… 就…… 　 He had no sooner bought the car than he sold it.

發(fā)生的動(dòng)作也可用一般過(guò)去時(shí)表示：I told them the news after you (had) left. 你走后我把這消息告訴了他們。As soon as I (had) put the phone down it rang again. 我剛把電話一放下，它又響了。(3) 在一定的語(yǔ)境中，表示過(guò)去未曾實(shí)現(xiàn)想法或打算的過(guò)去完成時(shí)也可用一般過(guò)去時(shí)表示：He hoped to come with us, but he was too busy. 他本想同我們一起來(lái)的，但他太忙了。I thought I could go, but I can’t. 我原認(rèn)為我能去，但我(現(xiàn)在)去不了。【注】若沒(méi)有明確的語(yǔ)境，則宜用過(guò)去完成時(shí)用法解說(shuō) 1. 過(guò)去完成時(shí)的基本用法過(guò)去完成時(shí)與現(xiàn)在完成時(shí)相似，也有“已完成”和“未完成過(guò)去完成時(shí)表示過(guò)去未曾實(shí)現(xiàn)的想法，否則可能有歧義，如說(shuō)I hoped to pass the examination. 它只表明過(guò)去想通過(guò)考試，但并未說(shuō)明通過(guò)與否。如說(shuō) I had hoped to pass the examination，則表示過(guò)去想通過(guò)考試，但實(shí)際上未通過(guò)。不過(guò)在過(guò)去式后接不定式的完成式也可明確表示過(guò)去未曾實(shí)現(xiàn)的想法，如 I hoped to have passed the examination。? ?

行時(shí)之后也可接具有"突然"之意的when分句。 二、將來(lái)完成時(shí)的用法有以下幾點(diǎn)： 1、構(gòu)成：will/shall have +過(guò)去分詞 1）We hope it will have stopped raining before we set off for the picnic. 我們希望在出發(fā)去野餐以前雨就已經(jīng)停了。 2）I'll have done all the work by the time you are back this evening. 你們今晚回來(lái)的時(shí)候我就將做完所過(guò)去完成進(jìn)行時(shí)容易和將來(lái)完成時(shí)混淆，從而導(dǎo)致在考試中把時(shí)態(tài)選錯(cuò)，造成有的工作了。 2、用法： 1. 表示在將來(lái)某一時(shí)刻將完成或在另一個(gè)未來(lái)的動(dòng)作發(fā)生之前已經(jīng)完成的動(dòng)作。注意：常與將來(lái)完成時(shí)連用的時(shí)間狀語(yǔ)有： by (the time / the end of ) + 表示將來(lái)時(shí)間的短語(yǔ)和句子； before (the end of ) + 表示將來(lái)時(shí)間的詞語(yǔ)或句子； when, after等加上表示將來(lái)動(dòng)作的句子等。 例如： 1）By the year 2050, scientists probably will have discovered a cure for cancer. 到2050年，科學(xué)家們可能已經(jīng)找到治愈

過(guò)去完成進(jìn)行時(shí)由“had been +現(xiàn)在分詞”構(gòu)成。它的用法是表示從過(guò)去某一時(shí)間開(kāi)始一直延續(xù)到另外一個(gè)過(guò)去在這所學(xué)校教書(shū)已經(jīng)10年了. 10.He has done a lot of work in the past two years. since 在現(xiàn)在完成時(shí)中意為自...以后自...以來(lái)，時(shí)間狀語(yǔ)常用since加一個(gè)過(guò)去的時(shí)間點(diǎn)或for加一段時(shí)間或by加一個(gè)現(xiàn)在時(shí)間。 如果不是時(shí)間點(diǎn) 也不是時(shí)間段 還有什么別的時(shí)間啊 ?具體情況具體對(duì)待吧 最好會(huì)翻譯句子的意思 在適當(dāng)?shù)倪x擇for和since 比如說(shuō) 1. He has had a house since 2005. ? 他自從2005年以來(lái)就擁有了一套房子. ? ? ?? 2. The play cat has been on for half an hour. 短劇《貓》已經(jīng)開(kāi)演半個(gè)小時(shí)了.
