回答1:

  • It’s + adj. + (of / for) sb to do sth. 译作“(某人)做某事是…的”。It 是形式主语,不定式结构是真正主语。of / for后面的sb是不定式的逻辑主语。

  • 1. 当形容词是可修饰人的形容词,即sb和adj.有主系表关系时,sb前用of。如 It’s clever    of you to answer the question so quickly. / It’s kind of you to help me a lot. 这样的形容词有:kind, nice, rude, clever, silly, foolish等。

  • 当形容词是不可以修饰人的形容词,即sb和adj.没有主系表关系时,sb前用for。如 It’s  easy for her to clean the window by herself. / It’s important for us to learn English well. 这样的形容词有:easy, hard, difficult, important, necessary, dangerous等。

  • 例句:it is nice of you to help me.你帮助了我,你真好.

    it is difficult for him to learn Chinese.学习中文对他来说太难了.
