good kind nice cleverright careful rudepolite foolish silly creative careless wrong selfish humorous honestgenerous wise It is ＋形容词＋ of +sb+ (not)to do sth.

难点： It is ＋形容词＋ of sb to do sth. It is ＋形容词＋ for sb to do sth. 如何区别？

★ 首先, 两者使用的形容不同， …for sb. 的句型通常使用表示客观情况的 形容词， …of sb. 的句型一般用表示 主观感情、人物性格的形容词。如 ： It is hard for him to drive the car. It is careless of the girl to leave her bag on the taxi.

★ 其次， …of sb. 句型一般都可以转 换成带一个不定式作状语的句子，而 …for sb. 的句型则不可以这样转换。 如： It was very kind of you to help me. → You were very kind to help me.

1.It is nice of you to bring me the newspaper. 2.It is implite of Tom not to say hello to his friends. Change the sentences: You are nice to bring me the newspaper. Tom is impolite not to say hello to his friends. → →

★后面能够接 …for sb. 的常见形容词有： hard/difficult ( 难的 ) easy ( 容易的 ) interesting ( 有趣的 ) important ( 重要的 ) necessary ( 必要的 ) uninteresting / boring ( 无聊的 ) possible ( 可能的 ) impossible ( 不可能的 ) unnecessary ( 不必要的 )
