It's + adj.+ for sb.+ to do( sth.) 与 It's + adj.+ of sb.+ to do( sth.)的区别为：形容词作用不同、表述方式不同、指代不同
一、形容词作用不同
1、It's + adj.+ for sb.+ to do( sth.)：用of时形容词就用来形容宾语人物的。
2、It's + adj.+ of sb.+ to do( sth.)：用for是因为前面的形容词是来描述do后面的事物的。
二、表述方式不同
1、It's + adj.+ for sb.+ to do( sth.)：形容词是描述不定式行为者的性格、品质的。
2、It's + adj.+ of sb.+ to do( sth.)：形容词仅仅是描述事物，不是对不定式行为者的品格进行评价。
三、指代不同
1、It's + adj.+ for sb.+ to do( sth.)：先给出定论，在描述事情。
2、It's + adj.+ of sb.+ to do( sth.)：先给出人物，在描述事情定论。
比如：it‘s nice of you to help me.=you are nice to help me.
1 It’s very kind of you to help me. 你能帮我，真好。
2 It’s clever of you to work out the maths problem. 你真聪明，解出了这道数学题。
用for 是因为前面的adj是来描述do后面的sth。即形容词仅仅是描述事物，不是对不定式行为者的品格进行评价，用for sb.，这类形容词有difficult，easy，hard，important，dangerous，（im）possible等。如
1 It’s very dangerous for children to cross the busy street.
对孩子们来说，穿过繁忙的街道很危险。
2 It’s difficult for us to finish the work. 对我们来说，完成这项工作很困难。
