  2)另一类是某些使役动词,如make, let,have等。如:

  Let him do it.让他做吧。

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

  (注):

  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,如:

  He was seen to come.

  The boy was made to go to bed early.

  ②在动词find与help之后,不定式可带to亦可不带to,如:

  He was surprised to find the sheep (to) break fence at this season.他发现羊在此季节越出栅栏,感到惊讶。

  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,他们没有别有别的办法。

  (4)不定式与动名词的逻辑主语和分词独立结构

  1)不定式的逻辑主语为:for +名词(或代词宾格)+ 不定式。例如:

  I found it impossible for him to do the job alone.我发现他—个人干这活是不可能的。

  (注)在表示人物性格、特性等的形容词后面,常用of引出不定式的逻辑主语。例如:

  It was wise of him to do that.他那样做是明智的。

  2)动名词的逻辑主语为;①人称代词的所有格+动名词;②名词's+动名词。例如:

  Tom insisted on my going with them.他坚持要我和他们一起去。

  He dislikes his wife's working late.他不喜欢他妻子工作得很晚。

  3) 某些形容词,如:careless等不定式后可以加of来引导出其逻辑主语。这类词主要有:absurd, bold, brave, courageous, careful, careless, clever, wise, foolish, silly, stupid, good, nice, kind thoughtful, considerate, greedy, generous, honest, modest, polite, rude, cruel ,selfish, wicked, wrong等

  It is very kind of you to help me.你帮助我太好了。

  间或也可用for + there to be表示(而且there后面的不定式只能是to be)。

  It's a great pity for there to be much trouble in the company.太遗憾了公司里有这么多的麻烦。

  7.非谓语动词中的有关句型

  (1)动名词作主语的句型

  1)Doing...+ v. Reading is an art.阅读是门艺术。Seeing is believing.眼见为实。

  2) It is + no use, no good (fun, a great pleasure, a waste of time, a bore...)等名词+doing sth.

  It is no use crying.哭没有用。It is no good objecting.反对也没有用。

  It is a great fun playing football.打篮球很有趣。

  It is a waste of time trying to explain.设法解释是浪费时间。

  3)It is + useless (nice, good,interesting, expensive等形容词)+ doing sth.

  It is useless speaking.光说没用。

  It is nice seeing you again.真高兴又遇到了你。

  It is good Playing chess after supper.晚饭后弈棋挺好。

  It is expensive running this car.开这种小车是浪费。
