一、結(jié)構(gòu)形式

過去完成進行時由“would have been+現(xiàn)在分詞”構(gòu)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(xù)到過去將來某一時間。動作是否繼續(xù)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(xué)期末，他就學(xué)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.
