英文句型一問 - modal verb + present perfect tense

「could have」通常是用來表示以前的可能性，並且暗示所說的那件事並沒有發生。

例如： I could have passed the exam, if I had studied harder.

這個「could have」，與「would have」及「should have」一樣，都暗示了所說的事並沒有發生。

「could have」與「would have」的分別在於「would have」所表示的可能性頗高，而「could have」所指的只是其中一個可能性。而「should have」則是指應做的事沒做，帶有後悔含義。例如：

A: I forgot to buy a Mark Six ticket yesterday. How much was the jackpot?
B: You could have won 10 million dollars.
A: I should have asked you earlier. I would have bought it if I had knew the jackpot was so big.

因此，「Anybody could have said that」是說「當時任何人都可以說了那些話」

「could have」，「would have」，及「should have」的詳細解說請看 BBC 的 Ask About English：
