为什么用is adj.for sb?

作者&投稿:雪耐 (若有异议请与网页底部的电邮联系)
~ 用of 的话,adj就用来形容sb的。即形容词是描述不定式行为者的性格、品质的,如kind,good,nice,right,wrong,clever,careless,polite,foolish等,用of sb.。故可以换成 sb is adj to do
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。

祝你假期愉快!加油!不明白再问!如果帮到你,请采纳,谢谢!
