( 此处用不定式得被 动语态作定语表明 you 不就是 post 动作得执行者。 )4、 在某些“形容词不定式”做表语或宾语补足语得结构中,句子得主语或宾语又就是 动词不定式得逻辑宾语时,这时常用不定式得主动形式表达被动意义。这些形容词有 nice,easy,fit,hard,difficult,important,impossible,pleasant,interesting 等。例 This problem is difficult to work out 、(可瞧作 to work out 省略了 for me) 、5、 在 too to结构中,不定式前面可加逻辑主语,所以应用主动形式表示被动意义。 例 This book is too expensive (for me)to buy 、6、 在 there be句型中,当动词不定式修饰名词作定语时,不定式用主动式
