It is+形容词+ of sb to do sth和It is+形容词+ for sb to do sth有什么区别

Question

如题所述

Answer 1

It is+形容词+of sb to do sth 中的形容词是形容人的品质的，例如：
It's kind of you to help me.
It's nice of you to help me.
It is wise of them to turn down the suggestion.他们很明智，拒绝了这个建议。（强调的是them是明智的。）

而It is+形容词+for sb to do sth中的形容词则是形容事物的性质的，例如，
（1）It is wise for them to turn down the suggestion.他们拒绝这个建议是很明智的。（强调的是to turn down the suggestion这件事是明智的。）
（2）It is impossible for me to finish the job.
（3）It is possible for you to get there in only 15 minutes.
（4）It's hard for him to give up smoking.
（5）It is important for him to finish the task in time.
（6）It is good for you to study hard in English.
（7）It is difficult for me to learn English.
（8）It is easy for me to climb that tree.
（9）It is very dangerous for the children to cross the street.
（10）It is necessary for you to learn from others.
（11）It is useful for you to learn how to repair TV sets.
（12）It is exciting for the children to play bumgee jumping.
（13）It is useless for you to quarrel with him.
（14）It is wonderful for us to join in the contest.
（15）It is wrong for you to do this.
（16）It is unwise for you to accept his gift.
（17）It is right for you not to accept his gift.
（18）It is horrible for me to go through the forest in the night.
（19）It is nice for me to work with her.
（20）It is interesting for me to go to movies with her.
（21）It is a pity for me not to marry her.
最后一例中的a pity不是形容词，但意义上也相当于一个形容词。

顺便说一下，楼上的第1、4、6、7句也对。但第2、5句中的for应改为of，第8句中的excited应改为exciting（因为excited只能指人的心理活动，在这样的句子结构中它只能与of搭配）。请楼上的别见怪，我是就事论事哟。
