die 是动词，没有被动态，所以没有 has been died 这种说法。请不要被误解一般来说，has been dead这种说法用在带for / since 的句子里，如：

He has been dead for 10 years. 他已经去世十年了。

因为遇到for 10 years 或是 since 2008 这类句子的时候，前面的动词必须是延续性动词，而die(死)是一个瞬间动词，所以要用has been dead 代替。

has died 可以用，比如

His dog has just died. 他的狗刚死了。has后面是必须加过去分词，但是你看，has been ,这里的been 已经作has的分词了呀~~所以has been 后面只能跟die的形容词形式了，即dead,在现在时中是 be dead,在完成时中当然是has been dead了。下一个问题，据我所知，好像还没听过有 has been died 的说法，如果有be died，也只能作被动，has been died 被死了,是没有这样的讲法的
