the question is difficult to answer.

  • 例句:

    It's difficult to answer the question.

    相信这个句型你很熟悉.It's+形容词+for sb.to do sth.对某人来说做某事……

    例句中略去了for sb.

    这个句型叫it做形式主语,那么真正的主语是什么呢?就是后面的 to do sth,所以句子可以还原成 Answer the question is difficult .这句语法是错的,动词不能直接做主语,要改成

    Answering the question is difficult .

    用动名词做主语,而且还带了宾语,Answering the question整体作主语,显得头重脚轻,所以就把answer放到句末去,那还得回到最开始的It's+形容词+for sb.to do sth.句型,保留了to do不定式.所以就成了.The question is difficult to answer.

    另外,这是习惯用法,一般不用被动语态,从语法上说,你想用be answered不会错,从惯用法上说,很少有人这么用.
