高中英語十六種時態用法詳解之過去將來完成進行時
導語：中學英語涉及到的時態一共有16種，下面給大家準備了過去將來完成進行時用法說明，希望對大家復習備考有幫助。
一、結構形式
過去完成進行時由“would have been+現在分詞”構成。
二、用法歸納
過去將來完成進行時表動作從過去某一時間開始一直延續到過去將來某一時間。動作是否繼續下去，由上下文決定。如：
He said that by the end of the spring term he would have been studying English for three years. 他說到了春季學期末，他就學了三年英語了。
I want you thinking of food and wine, because these last years would have been miserable for you. 我要你只想吃喝，因為最近幾年你的生活夠苦的。
在間接引語中，將來完成進行時通常要改為過去將來完成進行時。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.
