過去將來完成進行時與虛擬語氣
過去將來完成進行時是英語時態中比較常見的一種，但是，大家對它的用法可能還是不太瞭解。今天，小編爲大家準備了相關的語法知識，將要爲大家來講解一下：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. 事故發生的時候，我坐在車子的後座，因爲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裏的話，我就會坐在前面了。
一、過去將來完成進行時的情態意義
“would have been+現在分詞”結構除用於表示過去將來完成進行時外，有時其中的 would 也可能是情態動詞，具有情態意義，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. “你找到什麼有趣的工作啦?”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，一般語法書也講得到很少，所以能找到的權威例句也很少。爲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：
