  三、动词不定式的主动形式表示被动意义的常见结构

  (1)动词不定式和所修饰的词之间是被动关系,但不定式的逻辑主语在句中出现时,用不定式的主动形式表示被动含义。

  Do you have anything to say?

  你有什么话要说吗?(虽然say与anything之间为动宾关系,但句中出现了say的逻辑主语you)

  With so much housework to do, I can't go to the concert.

  有这么多家务要去做,我不能去音乐会。(to do与things之间为动宾关系,与I是主谓关系。)

   (2)在某些"形容词+不定式"作表语或宾语补足语的结构中,句子的主语或宾语是动词不定式的逻辑宾语时,常用不定式的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。

  This problem is difficult to solve.

  这个问题很难解决。

  (3)在too ... to ...; enough ... 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。

  This book is too expensive (for me) to buy.

  这本书太贵,我买不起。

  (4)在there be句型中,当动词不定式作定语修饰名词时,用主动形式,重点在人;用被动形式,重点在物。

  There is no time to lose (to be lost).(用to lose可看成for us to lose; 用to be lost,重点在时间。)

  没有时间去浪费。

  (5)be to blame用主动形式表示被动意义。

  Who is to blame for starting the fire?

  谁应为引发火灾负责?
