過去將來完成進行時是英語時態(tài)中比較常見的一種，但是，大家對它的用法可能還是不太了解。今天，小編為大家準備了相關的語法知識，將要為大家來講解一下：過去將來完成進行時的概念和用法，一起來看看吧！

在特定的語境中，有時過去將來完成進行時可用虛擬語氣中。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)生的時候，我坐在車子的后座，因為湯姆的小兒子坐在前邊他的身旁。要是湯姆的孩子沒坐在那里的話，我就會坐在前面了。

一、過去將來完成進行時的情態(tài)意義

“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。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。他知道海倫一定會一直想這件事的。

二、過去將來完成進行時補充例句

過去將來完成進行時不是一個常用時態(tài)，一般語法書也講得到很少，所以能找到的權威例句也很少。為滿足部分高級讀者朋友的需要，我們特從“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.
