英语句子中什么时候用“of”,什么时候用“for”?It is silly of sb to do

若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..It’s very kind of you to help me.你能帮我,真好.It’s clever of you to work out the maths problem.你真聪明,解出了这道数学题.若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.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.It’s difficult for us to finish the work.对我们来说,完成这项工作很困难.注 意 ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ of sb.的句型通常都可转换为不定式作状语的句子,但for sb.句型不可以.It’s very nice of you to offer me a seat.= You are nice to offer me a seat.十分感谢你给我让座.It is careless of him to lose so many things.= He is careless to lose so many things.他丢了这么多东西,真是太粗心了.It’s very important for you to practise your oral English in daily life.在日常生活中练习你的英语口语非常重要的.这句话不能说成：It is very important of you to practise….======以下答案可供参考======供参考答案1:It is good for sb是个固定搭配
