continue to do和continue doing在用法和意义上有什么区别?谢谢

to do强调停下手头的事情（后）继续做某事,doing就是不停做某事eg：I continued to write my book when I had finished my homework。我做完作业后继续写书（没停,但做的事情不一样,强调：忙死我啦）I continued writting my book after a short rest。短暂的休息后我继续写书（暗含的意思是一直在写书,同一件事,强调：这破书不好写啊）to do强调我没闲着,一直在忙,强调动作,doing强调事情,这件事我一直在做。至于楼上说的做没做完,看时态和语态吧,语言不能死学,多读多说你就会明白好多东西书上说的不严谨,你自个儿体会一下
