动词的省略
有些动词believe, find, think, feel, consider, imagine, prove等后作宾补的结构to be + n. / adj.中的to be可以省略。
感官动词see, hear, feel, watch, notice 等以及使役动词let, make, have后作宾补的动词不定式,其中的不定式符号to要省略,但变为被动结 构时,to必须保留。
在can not but, can not choose but, can not help but之后的动词不定式一般不带to;but之前有实义动词do的某个形式do, does, did, done 时,也不带to, 否则要带to。
在并列结构中为了避免重复。在why, why not 引导的特殊问句中后跟省略to的动词不定式。
