You look so tired, what have you been doing?与you look so tired,what have you done?的差异
You look so tired, what have you been doing?
you look so tired,what have you done?
请问这两句有什么不同?它们分别是什么时态?他们对应的中文翻译是什么?
谢谢!

Answer 1

不同在于前一句的意思是你一直在做什么,这个动作从过去的时间一直持续到的现在的,而且,现在还在持续.是一个现在完成进行时,“你看起来如此疲倦,你一直在做什么呀?”
后一句的意思是你做了什么,这个动作现在已经结束了,动作已经完成,是个现在完成时的句子,“你看起来如此疲倦,你做了什么?”
