it is great to him与 it is great for him 有什么区别

1 it is great to him --------裏面的 it 往往是真正主语：郑段 it (== such work) is great to him. to是介词，解释为“对 -- - 来说”。

2it is great for him ------裏面的 it 往往是形乎拦式主语，而真正主语在已知的语境中被省略了：

It is great for him (to do such important work). ------这里的 to do such important work== it ,是真正主语，喊顷誉for him 是逻辑主语。

应该是it’s great to eat out出去吃激桥饭数铅轿只很高兴的，这是it’s +adj.+(for)+(sb.)+to do sth.做什么事情是怎么样的薯肆

而it’s great for是 ...是伟大的意思

It形式主语源雹 is系动词 great表语 （for you to answer the question真正主语）

你能慎裂败回答这个问题太好了。
