D
解析试题分析:根据句式结构可知,本句是一个固定句型:It is +adj.+for/of sb. to do sth.it在此处做形式主语,没有意思;若形容词是描述不定式行为者的性格、品质的,如kind,good,nice,right,wrong,clever,generous,careless,polite,foolish等,用of sb。如果是表示事物特征的词,如important,impossible,easy等,应用for。所以本题选D。
考点:本题考查介词
点评:完成本题首先应该掌握这个句型的结构,本句型经常考查it或of/for或to do;关于of和for的区别主要体现在:若形容词是描述不定式行为者的性格、品质的,如kind,good,nice,right,wrong,clever,careless,polite,foolish等,用of sb.。若形容词仅仅是描述事物,不是对不定式行为者的品格进行评价,用for sb.,这类形容词有difficult,easy,hard,important,dangerous,(im)possible等。
