Question

It is+形容词+for sb to do sth与It is+形容词+of sb to do sth有什么区别？分别是什么意思？

Answer 1

It is+形容词 + for sb to do sth 做某事对某人有好处

It is+形容词+of sb to do sth 一般指某人做某事很好/不好

例如：It is kind of you to help me. 你能帮助我太好了。
It is bad for you to drink too much. 喝太多酒对你身体不好。

Answer 2

呃，这个怎么说呢，打个比方吧，当你说It is 困难 for sb to 吃三十个包子时，你是说吃三十个包子这件事很难做。而说It is 牛逼 of sb to 吃三十个包子时，你是指那个人因能吃三十个包子而其人显得很牛逼。
所以前者批事，后者指人，不知道你懂了没有？懂了的话，留个名。

Answer 3

前者 for 是对于 的意思，it's good for you to stop smoking.戒烟是为你好。

能转换成sb is/are +形容词的 就是 It is+形容词+of sb to do sth
