语法问题,make to do ;make doing
make为使役动词,其后跟省略to的不定式作宾语补足语,即：make 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.
make sb.doing sth 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.)
还有make sth.done,指让别人帮助完成某事,例如：He madehave his bike repaired.(他让人帮他修理自行车.)
