Its very kind you to say so
用for 还是of两者有什么区别 

Its very kind you to say so用for 还是of两者有什么区别
1.It's necessary ___for___us to master a language.
2.It's unwise ___of___them to refuse our help.
3.It is very important ___for__us to study some rules.
4.It is unpracticable ___for___us to finish such a difficult task
in such short time.
5.It's wrong __of / for___a person to think only of himself. (这一句for / of 都可以,看你站在什么立场上,出题人不太严谨)
窍门:
如果被认为是普遍现象,就用for,如:
1.It's necessary ___for___us / people to master a language.
2 It is very important ___for__us / learners to study some rules.
3 .It is unpracticable ___for___us / anyone to finish such a difficult task in two days.
如果被认为是某个人的个别现象,我们就用of,如:
1 It was wrong of me / John / us / the girl to be late again ans again.
2 It is very kind of him to give us so much help. (也就是说,he肯,但别人不一定肯)

of
到底用for还是of有一个小窍门,能改成sb is kind to do 的用of,不能的用for
如:本句可改成 You are very kind to say so.
It's hard for you to speak French. 是speak French很难,不是you are hard

一楼除了第一题以外都对,不能只说what hard work,要 what a hard举个例子吧、:It is not very hard for you to find English is

应该是用for的 用of有点别扭
