非谓语动词常考的其他结构

(1)疑问词+不定式结构 87K)qsv8  
  疑问词who,what,which,when,where和how后加不定式可构成一种特殊的不定式短语。它在句中可以用作主语、宾语、表语和双重宾语。如: E~>6*_?  
  When to start has not been decided.何时动身尚未决定。(主语) bS<@Rd{g  
  I don't know what to do.我不知道该怎么办。(宾语) ;ULC|7rL  
  The difficulty was how to cross the river.困难在于如何过河。(表语) ?&"^ \p  
  I can tell you where to get this book.我可以告诉你哪里可以买到此书。(双重宾语) vaj66nV  
  (注)A.有时疑问词前可用介词,如: >$mSF Jz5S  
  I have no idea of how to do it.我不知道如何做此事。 _=L;`~=C9e  
  B.动词know 后面不能直接跟不定式作宾语,只能跟疑问词(如:how, what)+不定式: x}.d`=  
  While still a young boy, Tom knew to play the piano well and as he grew older, he wrote operas, the most famous of which is Carmen. s\W  
  (2)介词except和but作“只有…,只能…”讲时跟不定式结构(but与不带to的不定式连用)。 &'7"i~pC  
  When the streets are full of melting snow, you cannot help but getting your shoes wet. %;Z bQ9  
  (3)不带to的不定式 iw fp'  
  1)在表示生理感觉的动词后的不定式不带to。这类词有: p? ?/r

  notice注意 see看见 look at看 hear听 yb{Q,Dz

  Let him do it.让他做吧。 EB>B,#  
  I would have you know that I am ill.我想要你知道我病了。 JYd7@Msfc  
  (注): DvX3/z#T

  He was seen to come. g?~Tguv

  ②在动词find与help之后,不定式可带to亦可不带to,如: 'yd@GQM&

  3)在do nothing/anything/everything but(except)结构中。例如: Q)S>VDLA  
  Last night I did nothing but watch TV.昨天晚上,我除了看电视别的什么也没有干。 /u)Rppu
