make to do和make doing 是两种表达方式.make、have、let三个为使役动词,其后跟省略to的不定式作宾语补足语,即：make\have\let sb. do sth.（让某人做某事）例如:The teacher made him wait outside.(主动语态)；在被动语态的句子中,则要还原不定式的符号to,即：He was made to wait outside.
也有make\have sb. doing sth.的结构,意思为：让某人一直做某事,强调动作的持续性.例如：The boss made the workers working from dawn to dark.(老板让工人们从黎明一直工作到天黑.)
另外还有make\have sth. done,指让别人帮助完成某事,例如：He made\have his bike repaired.(他让人帮他修理自行车.)
