用“不带to的动词不定式”结构做宾补的动词主要有2类：

1.使役动词have, let, make等；

2.感官动词“五看两听一感觉”，即五个看的动词：see, watch, notice, observe, look at;

两个听的动词：hear, listen to; 一个感觉：feel.这些动词都可以跟sb do sth, 表动作完成；

也可以跟sb doing sth，表动作正在进行。

We saw the car stop.

▲但在被动句中，原不带to 的不定式宾补还原为带to 的不定式做主语补语：They made us wait for three hours.-----We were made to wait for three hours.
