make、have、let三個(gè)為使役動(dòng)詞，其后跟省略to的不定式作賓語補(bǔ)足語，即：makehavelet sb.do sth.（讓某人做某事）例如:The teacher made him wait outside.(主動(dòng)語態(tài))；

　　在被動(dòng)語態(tài)的句子中，則要還原不定式的符號to,即：He was made to wait outside.也有makehave sb. doing sth.的結(jié)構(gòu)，意思為：讓某人一直做某事，強(qiáng)調(diào)動(dòng)作的持續(xù)性。

　　例如：The boss made the workers working from dawn to dark.(老板讓工人們從黎明一直工作到天黑。)
