make后面可以加to do也可以加doing。
make为使役动词,其后跟省略to的不定式作宾语补足语；在被动语态的句子中,则要还原不定式的符号to
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：makehave 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makehave 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。) )
