是be rude of sb还是be rude for sb,另外说下它的意思

原来你是问这个。我明白了。 你应该问，是it is rude of sb to do sth 还是 it's rude for sb to do sth.答案是第一句是对的。it is rude of children to stare at strangers in the street 意思是，在街上盯着陌生人看是粗鲁的。 it is kind/good/nice/wise/stupid/clever/rude/polite/impolite...of sb to do sth，而it is important/necessary/essential/vital/helpful/ ... for sb to do sth 【俊狼猎英】团队
