英语可以说assist sb in sth和assist sb with sth，也可以说assist sb to do sth和assist sb in doing sth。我想请问一下：可以说assist sb with doing sth吗？比如以下三句：
The boss asked me to assist him to carry through his great plan.
The boss asked me to assist him in carrying through his great plan.
The boss asked me to assist him with carrying through his great plan.
