過(guò)去將來(lái)時(shí)
由“shall或will的過(guò)去式should或would+動(dòng)詞原形”構(gòu)成。
表示在過(guò)去某一時(shí)刻之后將要發(fā)生的動(dòng)作或情況。 過(guò)去將來(lái)時(shí)態(tài)如果出現(xiàn)在從句中， 則主句謂語(yǔ)動(dòng)詞通常是是一般過(guò)去時(shí)。如：
e.g. We wanted(想要) to know (知道)when the English class would begin(開(kāi)始).
過(guò)去將來(lái)時(shí)的否定和疑問(wèn)結(jié)構(gòu)：
It would be fine(晴朗的). 天氣會(huì)晴朗起來(lái)
It wouldn’t be fine.
Would it be fine?
