Ⅰ.die 是不及物动词，一般指因生病，负伤等原因而死。且是非延续性动词(瞬间动词)，不能和表示一段时间的状语(for+段时间短语;或since……)连用。如：
① He was born in 1847 and died in 1913. 他生于1847年，死于1913年。
② His grandfather has been dead for two years. = His grandfather died two years ago. 他爷爷去世两年了。
③ He died ten years ago.他是10年前死的。(不可说：He has died for ten years. 或应说：It is 10 years since he died)
Ⅱ.dead 是形容词，表状态，可在句中作表语和定语。但不可作谓语。如：
① He is dead, but his name sill live for ever in our hearts.他虽然死了但他的名字将永远活在我们心中。
② It doesn’t look like a dead fox.看来不像一只死狐狸。
Ⅲ.death是抽象名词，只能在句中作主语或宾语。如：
① The murderer was sentenced to death. 杀人犯被宣判死刑。
② I heard of his death when I got to his house. 我一到他家就得知他已经去世了。
