“keep on doing”是英语中常用的动词短语,核心含义是“持续做某事;反复做某事;坚持做某事”,强调动作的重复性、连续性或“不顾阻碍的坚持”。以下是详细解析:
侧重“动作反复发生”或“在困难/干扰下依然继续”,隐含“不放弃”的态度。例如:
Keep on trying—you’ll succeed!(继续尝试——你会成功的!)(鼓励坚持)
The child kept on asking questions about space.(孩子一直问关于太空的问题。)(反复提问)
后面必须接动名词(doing),不能接不定式(to do)。
✅ 正确:Keep on working hard.(继续努力工作。)
❌ 错误:Keep on to work hard.
人作主语:表示主动“坚持/反复做某事”。
例:She keeps on practicing the piano every evening.(她每天晚上坚持练钢琴。)
物作主语:表示“持续发生的自然/客观动作”。
例:The rain kept on falling all day.(雨下了一整天。)
根据语境使用不同时态(核心动词“keep”随时态变化,“on doing”固定):
一般现在时:He keeps on forgetting his keys.(他总忘带钥匙。)(反复发生)
一般过去时:They kept on walking until they reached the top.(他们一直走到山顶。)(持续动作)
现在进行时:Why are you keeping on interrupting me?(你为什么一直打断我?)(当前反复的动作)
常用来表达:
鼓励坚持:Keep on going—don’t stop!(继续走——别停!)
描述反复行为:My dad keeps on telling the same joke.(我爸总讲同一个笑话。)
克服阻碍:She kept on studying even when she was tired.(即使累了,她还是坚持学习。)
两者都表示“持续做某事”,但侧重不同:
keep doing:强调动作的连贯性(几乎不中断)。
例:He kept doing his homework for 3 hours.(他连续做了3小时作业——没停。)
keep on doing:强调动作的反复性(可能中断后又继续)或“坚持”。
例:He kept on doing his homework even when his friends called.(即使朋友打电话,他还是接着做作业——中断后继续。)
1、 鼓励:Keep on singing—you have a great voice!(继续唱——你嗓子很好!)
2、 抱怨:The dog kept on barking all night.(狗整夜不停地叫。)
3、 坚持:I kept on practicing until I could play the song perfectly.(我一直练到能完美演奏这首歌。)
“keep on doing”是强调“反复/坚持做某事”的短语,后接动名词,适用于鼓励、描述持续行为或克服阻碍的场景。记住:不接不定式,只接动名词!
