  2)如果主语是不定式(表示条件),表语也是不定式(表示结果)。

  1)现在分词作状语时,现在分词的动作就是句子主语的动作,它们之间的关系是主动关系。

  Not knowing what to do, he went to his parents for help.

  由于不知如何办是好,他去找父母帮忙。

  2)过去分词作状语时,过去分词表示的动作是句子主语承受的动作,它们之间的关系是被动关系。

  6.非谓语动词常考的其它结构

  (1)疑问词+不定式结构

  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。

  (2)不带to的不定式

  1)在表示生理感觉的动词后的不定式不带to。

  这类词有: feel 觉得 observe 注意到,看到 overhear听到 watch注视 listen to听 perceive察觉,感知 notice注意 see看见 look at看 hear听

  2)另一类是某些使役动词,如make, let,have等。

  Let him do it.让他做吧。

  I would have you know that I am ill.我想让你知道我病了。

  ①上述感觉动词与使役动词转换为被动结构时.其后的不定式一般需带to,

  3)在do nothing/anything/everything but(except)结构中。

  例如: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。

  但是,如果谓语动词不是“do nothing,anything,everything”,那么but(except)所跟的不定式则仍须带。

  The doctor told him nothing but to stop smoking.医生除了让他戒烟,其它什么都没有说。

  There was nothing for them to do but to remain silent.除了保持沉默以外,他们没有别的办法。
