keep on doing sth用法?

on doing sth用法?

on doing用法:接以形容词、副词、as短语、现在分词(短语)、过去分词(短语)等充当宾语补足语的复合宾语,但不可接含动词不定式的复合宾语。
例句
Keep on doing what you are doing.继续做你正在做的事情。
keep on doing侧重点:指开始做某事,在做的过程中停歇一段时间,然后再接着做

keep doing与be doing的区别?

前者是保持做某事,强调的是动作的延续;后者是正在做某事,表示动作的正在进行

keep的用法,后面加动词的什么形式?

keep doing一直做某事,没有间歇。
keep on doing继续做某事。

keep doing什么意思?

keep doing, keep on doing keep doing表示不间断地做某事;keep on doing表示动作是时断时续的。
这两个词组均用来表示“不断做”的意思,但在涵义上有所不同。
1. keep doing和keep on doing都可表示“不断(老是)做某事”的意思,强调动作连续不断,每隔一会儿发生,这时两者可以换用。不同的是keep doing中的doing是动名词,作宾语。例如:John always kept (on) asking questions. 约翰总是问个不停。News of successes keeps (on) pouring in. 捷报频传。
2. keep doing还可表示连续不断的动作或持续的状态。keep on doing则没有这种用法。例如: We kept working in the fields in spite of the rain. 尽管下雨,我们还是坚持在地里干活。Why do the dogs keep barking 这些狗为什么不停地叫?
