It is impossible for a child ,用for,不用of
It is very nice of you 用of
关键看it is后面的形容词
如果是主观的形容词,比如,nice,good,careful,careless,selfish,(就是你可以自己改变,可以小心,也可以不小心)的这类形容词,用of
如果是客观的形容词,比如,important,这些是不依你的意志为转移的,用for这是一个固定搭配,不可以换的,后面那些都是一些表示情感品质的,像kind 也可以这样用
对于某某人 这个时候我们用for
It's very kind/nice/polite of you
表示一个人的品质的时候我们用of, of有‘的’的意思,属于某人的品行nice是用来说人的品质的,所以用of,不用for。
你所说的是两个句型。
1. It is necessary for sb. to do sth.
2. It is very kind of you to do sth.
如果一个形容词,在本句中是用来修饰人的(如2, you are kind), 就用第二个句型。否则,就用第一个。第一个是for.第二个是of
不能。
因为上一句的for表对象,,就是对某人来说,,不可能。
下面那个是of,是表示修饰的,是修饰you的。表示怎样的你。。。换成for了以后,就成了对我父母表达问候对你很好。。这样就不通顺了对不?
