(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。

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:
