易错句子His grandfather has died for three years.
正确表达His grandfather has been dead for three years.
die 是瞬间动词（终止性动词），不能与 for three years 这样的时间段连用；表示"去世后持续的状态"要用状态表达 be + 形容词 dead，即 has been dead。若要保留动词 die，应说 His grandfather died three years ago.

易错句子He dead last year.
正确表达He died last year.
dead 是形容词，只能作定语或表语（如 He is dead），不能单独充当谓语动词。汉语"他去年死了"里的"死"是动词，英语对应动词 die，表示过去发生的一次性动作要用过去式 died。
