I haven’t finished my homework today.I haven’t finished my homework now.today,now可以和现在完成时连用吗?

问题描述:

I haven’t finished my homework today.
I haven’t finished my homework now.
today,now可以和现在完成时连用吗?

I haven’t finished my homework today.对
I haven’t finished my homework now.对
可以连用
强调 对现在的影响

第二句有点不对。
最好是I ' haven't finished my homework until now.直至现在


today,now可以和现在完成时连用,因为现在完成时的关键就是强调对“现在”的影响。
你可以在网上查一下现在完成时的时间问题。
祝你进步!

这是对的,today,now从时间上看属于“现在”,所以可以用现在完成时

两句都不对.
today 和 now都可以和完成时用,这没问题,比如 I haven't seen Mike till now.I haven't had a meal today.
但问题是finish这个词,是瞬息动词,不能用作完成时,逻辑上不能说一直在finish,类似的瞬息动词还有die.
