keep 与 keep on 的用法区别  

  

  

两者均可后接动名词(不接不定式),区别如下:  

1. 表示反复发生的动作(即动作之间略有间隔)时,两者可互换。如:  

They kept (on) talking about it. 他们一直在谈论此事。  

My shoe laces keep (on) coming undone. 我的鞋带老是松开。  

2. 表示持续的状态或连续不断的动作(动作之间没有间隔)时, 通常只用 keep doing sth。如:  

He kept standing during the meeting. 开会时他一直站着。  

We kept hoping that they would have a chance to come to China some day. 我们一直希望他们什么时候有机会到中国来。  

3. 表示将一直在做的事继续做下去,通常只用 keep on doing。如:  

He kept on working after dark. 天黑了他还继续干。  

Don’t give up; keep on trying. 别灰心,继续努力。  

注:这样的 keep on doing可与 go on doing 换用。如:  

The boys kept [went] on doing their homework in spite of interruptions. 尽管有干扰,孩子们仍继续做自己的作业。  

4. 有时若意义明确,keep on 后的 doing sth 可省略,而 keep 后却不能省略 doing sth。如:  

The rain kept on for several days. 雨一连下了好几天。
