導(dǎo)語：中學(xué)英語涉及到的時態(tài)一共有16種，下面給大家準(zhǔn)備了將來完成進(jìn)行時用法說明，希望對大家復(fù)習(xí)備考有幫助。
一、結(jié)構(gòu)形式
過去完成進(jìn)行時由“will / shall have been+現(xiàn)在分詞”構(gòu)成。
二、用法歸納
用法一：表示動作從某一時間開始一直延續(xù)到將來某一時間，至于是否繼續(xù)下去，要視上下文而定。如：
She will have been having treatment all her life. 她將終生受到治療。
By the end of next month he will have been here for ten years. 到下月底，他在這兒就夠十年了。
By this time next year, we will have been doing business with each other for 20 years. 到明年這時候，我們的業(yè)務(wù)住來就滿20年了。
By the end of this year he’ll have been acting for thirty years. 到今年年底他當(dāng)演員就滿30年了。
用法二：表示一種經(jīng)常性反復(fù)進(jìn)行的持續(xù)性動作。如：
By the end of this month he will have been training horses for twenty years. 到了這個月底他馴馬就滿20年了。
