英語(yǔ)中過(guò)去將來(lái)時(shí)的含義是？

過(guò)去式是在詞后加ed
將來(lái)時(shí)是在句中加be
過(guò)去將來(lái)時(shí)表示過(guò)去某一時(shí)間點(diǎn)的將來(lái)的動(dòng)作,多用于間接引語(yǔ)里中.,在間接引語(yǔ)中,用來(lái)表示在實(shí)際說(shuō)話中是用將來(lái)時(shí)表示的動(dòng)作,就是說(shuō),如果以過(guò)去說(shuō)話的時(shí)刻為參考點(diǎn),這個(gè)動(dòng)作為將來(lái).過(guò)去將來(lái)時(shí)所表示的時(shí)間不一定是"過(guò)去",也不一定是將來(lái),完全取決于轉(zhuǎn)述的時(shí)間.過(guò)去將來(lái)時(shí)更重要的用法是表示各種程度的假設(shè).
