has died是錯誤的說法。has been dead表示“已經死了”，強調狀態(tài)如： He died. He has been dead.die是瞬間性動詞，所以不能用于現(xiàn)在完成時，所以has died是錯誤的用法。例句：The old man has been dead for a year.

has died和has been dead有什么區(qū)別

沒有has died這么一種用法，死亡不是延續(xù)性動詞，所以died不可用在現(xiàn)在完成時中，不可以說一個人從過去死到現(xiàn)在。

be dead表示狀態(tài)，這里用了完成時，就變成了has been dead，后面可以用for接一段時間詞。

例句：Uncle Wang died three years ago.=Uncle Wang has been dead for three years.

has been dead的例句

He has been dead for three years.

他已經死了三年了。

He has been now dead for many years.

他已死去多年。

I mean it has been dead for a couple of days.

我是說它已經死了幾天了。
