語法對(duì)于考研英語來說尤為重要，可以說是貫穿始終，縱然沒有具體明確的題目對(duì)考生進(jìn)行語法考查，但熟練掌握語法是取得考研英語高分的必要條件。小編整理了關(guān)于考研英語語法時(shí)態(tài)的系列文章，以下是2017考研英語語法時(shí)態(tài)詳解之過去將來完成進(jìn)行時(shí)，希望能對(duì)大家的復(fù)習(xí)有幫助!

過去將來完成進(jìn)行時(shí)

1.概念：表示從過去某時(shí)看至未來某時(shí)以前會(huì)一直在進(jìn)行的動(dòng)作。

2.基本結(jié)構(gòu)：should/would + have + been +現(xiàn)在分詞

3.例子：He told me that by the end of the year he would have been living there for thirty years.

他告訴我，到年底時(shí)，他就在那住了30年了。

4.用法

一、間接引語與過去將來完成進(jìn)行時(shí)在間接引語中，若主句為過去時(shí)態(tài)，則用于賓語從句中的間接引語則要把將來完成進(jìn)行時(shí)改為過去將來完成進(jìn)行時(shí)。如：I know by this time next week you’ll have been working here for 30 years.→I knew by that time he would have been working there for 30 years.She will have been teaching in this university for 20 years by this summer.→She told me she’d have been teaching in that university for 20 years by that summer.

二、過去將來完成進(jìn)行時(shí)與虛擬語氣在特定的語境中，有時(shí)過去將來完成進(jìn)行時(shí)可用虛擬語氣。如：At the time of the accident I was sitting in the back of the car，because Tom’s little boy was sitting beside him in front. If Tom’s boy had not been there I would have been sitting in front. 事故發(fā)生的時(shí)候，我坐在車子的后座，因?yàn)闇返男鹤幼谇斑吽纳砼?。要是湯姆的孩子沒坐在那里的話，我就會(huì)坐在前面了。

三、過去將來完成進(jìn)行時(shí)的情態(tài)意義“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(dòng)詞，具有情態(tài)意義，比較表示推測(cè)或猜想等。如：“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(huì)一直想這件事的。

四、過去將來完成進(jìn)行時(shí)補(bǔ)充例句過去將來完成進(jìn)行時(shí)不是一個(gè)常用時(shí)態(tài)，一般語法書也講得到很少，所以能找到的權(quán)威例句也很少。為滿足部分高級(jí)讀者朋友的需要，特從“英國國家語料庫”中查了部分例句，供大家參考：◇Latterly, they would have been reading Virgin books, watching Virgin videos and Virgin films.

◇New York was swathed in sunlight and the heat would have been stifling had it not been for a gentle easterly breeze blowing in from the Atlantic.

◇Maybe we, it may well be that you were with other people, I wonder what sort of things if you were in a condition of speaking, what sort of things you would have been saying to them.

◇Obviously no expense was being spared to make the night a success, and in different circumstances she would have been looking forward to it, but now, as silence settled over the car, she could feel herself growing tense.
