Question

lead sb (in) doing对吗？和to do什么区别?

Answer 1

lead to do 和doing根本就是两回事：
Lead sb. To do sth（导致、致使某人做某事） This leads him to make a mistake.
Lead sb. In doing sth（领导、引领某人做某事） This man leads us in going to BJ.
Lead后可以接双宾语 She led him a happy life.
lead sb. to doing，没见过这种语法，谁见过请举例，请不要自己想当然。

Answer 2

对。
前面是 领导某人正在做……，
后面to do是将要做……。
