在英語(yǔ)語(yǔ)法時(shí)態(tài)中，過(guò)去時(shí)態(tài)是我們經(jīng)常會(huì)用到的一種時(shí)態(tài)，過(guò)去將來(lái)進(jìn)行時(shí)也是一種比較抽象的時(shí)態(tài)，所以，在掌握過(guò)去將來(lái)進(jìn)行時(shí)時(shí)態(tài)的同時(shí)也一定要掌握它和別的時(shí)態(tài)的區(qū)別和比較，在我們平常的英語(yǔ)句子應(yīng)用中，比較容易混淆的是過(guò)去將來(lái)時(shí)和過(guò)去將來(lái)進(jìn)行時(shí)，讓我們先來(lái)了解一下它們之間的用法和區(qū)別：
一、過(guò)去將來(lái)進(jìn)行時(shí)的定義以及在英語(yǔ)句子中的用法解析：
1、過(guò)去將來(lái)進(jìn)行時(shí)的定義：過(guò)去將來(lái)進(jìn)行時(shí)表示就過(guò)去某一時(shí)間而言，將來(lái)某一時(shí)刻或某一段時(shí)間正在進(jìn)行的動(dòng)作，主要用于賓語(yǔ)從句中，尤其多用于間接引語(yǔ)中.
2、過(guò)去將來(lái)進(jìn)行時(shí)由should(would)+be+現(xiàn)在分詞構(gòu)成.
