keep on doing是坚持还是继续

keep on doing是坚持还是继续 第二个的中,keep doing =keep on doing =继续 做某事是不是? 继续做某事用英文怎么说?是carry on doing sth还是carry on with sth 还是carry o run是及物动词吗?keep on doing加run还是running? 是keep dancing 还是keep on dancing keep on doing sth 请问keep on doing和 keep doing在用法上有什么区别?还有,当表示“继续做某事‘时,keep on 坚持做某事,是hold on to do sth.还是 hold on to doing sth.有何区别? keep+doing后面doing是动名词还是现在分词? keep up 是坚持的意思,keep doing sth也是坚持的意思.二者有什么区别么 carry on doing与keep on doing 是keep sharp eye on 还是keep sharp eyes on
