Is anybody home？=有人到家/回家了吗/家里现在有人吗？（副词作表语表动态意味.sb be home =sb gets/arrives home）

Is anybody at home? 有人在家吗/屋里有人吗？（介词短语作表语表静态含义,sb be at home=sb be in ）

我知道语法结构不同，一个 home 是副词，一个是 at home 介词短语。我想问意思上有区别吗？

home,at home其区别如下

(1)home 作为副词，表示，回家，到家，在家，（之前出门在返回到家）多与表示位置移动的动态动词连用，get home, go home, come home, arrive home, bring home, hurry home。（作为副词，还可以作后置定语修饰前面名词）
