make、have、let三個為使役動詞,其后跟省略to的不定式作賓語補足語,即:makehavelet sb.do sth.(讓某人做某事)例如:The teacher made him wait outside.(主動語態(tài));
在被動語態(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,強調(diào)動作的持續(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。)
