如何区分It’s +adj.+of sb to do sth

Answer 1

有两种相似的句型

1. It's + adj+ of sb to do sth.   （可构成sb is adj.结构的）

It's kind/smart of sb to do sth. 某人做某事真是太善良/聪明了。

eg. It's kind of you to help us.  

It's smart of you to solve the proble like this.

2. It's + adj+ for sb to do sth

It's easy/simple/difficult/important for sb. to do sth 

对某人来说做某事很容易/简单/困难/重要

eg. It's important for us to study hard.

Answer 2

It is kind of you to help me.
这里形容词kind修饰of 后面的sb. 也就是you
按照翻译就是 你很友好
It is too hard for me to do this homework.
这里形容词hard修饰to后面的动词,do homework
这里按照翻译 做作业很难
不理解可以在问我~
