8BU6 Grammar 语言点

语法要点：

It is + adj + to-infinitive 做某事是…

该句型中的形容词表示不定式所具备的特征或客观情况。

•It is +adj.+ for sb to do sth. 对某人来说，做某事是…

•It is +adj. + of sb to do sth 某人做某事是（某人是….）该句型中的形容词描述的是人的特征、品质等。

It is +adj.+for sb+to do sth. 基本同‘It is +adj.+to do sth’,意思是：“对某人来说，做某事是......”

=Doing/To do sth. is +adj.=It is +adj. +that-clause

It is important for us to learn English well. =To learn /Learning English well is important for us.

=It is important that we learn English well.

相同点: for &of 后的人称代词都用宾格

不同的：①...for sb.的句型通常使用表示客观情况的形容词；...of sb. 的句型一般主观感情、人物性格的形容词。

② ...for sb.则可转换成Doing/To do sth.is +adj; 而...of sb.句型可转换成Sb+be+adj+to do sth . It’s kind of you to help me with my English.=You are kind to help me with my English.
