補充講解：
1. it＋is＋形容詞＋（for/of sb. ）＋動詞不定式短語。
對于這個句型中究竟用 for還是用of，一般遵循這樣的規(guī)則：
若形容詞是描述不定式行為者的性格、品質(zhì)的，如kind，good，nice，right，wrong，clever，careless，polite，foolish等，用of sb. 。
it’s very kind of you to help me. 你能幫我，真好。
it’s clever of you to work out the maths problem. 你真聰明，解出了這道數(shù)學(xué)題。
it’s very kind of you to say so. 你這樣說真是太好了。
若形容詞僅僅是描述事物，不是對不定式行為者的品格進行評價，用for sb. ，這類形容詞有difficult，easy，hard，important，dangerous，（im）possible等。
it’s very dangerous for children to cross the busy street.
對孩子們來說，穿過繁忙的街道很危險。
it’s difficult for us to finish the work. 對我們來說，完成這項工作很困難。
it’s important for us to keep the classroom clean. 保持教室干凈對我們來說是很重要的。
注意：
of sb. 的句型通常都可轉(zhuǎn)換為不定式作狀語的句子，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. 十分感謝你給我讓座。
it is careless of him to lose so many things.
