If this thing had happened that thing would have been happening.

作用

完成進行式可以用在第三類條件句,論及 if 子句中的動作未達成的後果,並將這樣的後果以未完成或持續進行的動作來表達。

舉例
  • If the weather had been better(但沒有), I'd have been sitting in the garden when he arrived(但我沒有).
  • If she hadn't got a job in London(但她有), she would have been working in Paris(但她沒有).
  • If I had had a ball I would have been playing football.
  • If I had known it was dangerous I wouldn't have been climbing that cliff.

完成進行條件式

任何動作的完成進行條件式都是由四個要素組成:
would + have + been + 現在分詞
現在分詞的構成是取動詞的原型,並在字尾加上 ing。

主詞 + would + have + been + 現在分詞
He would have been staying
They would have been going
完成進行條件式,以 To Work 為例:
