(回答的详细些,有条理些)
用now改写句子,now是现在进行时时间状语,意思就是将原句中的时态改为进行时。如:
I do homework in the evening.------- I am doing homework now.
i did homework yeaterday.---------I am doing homework now.追问
I do homework in the evening.------- I am doing homework now.
i did homework yeaterday.---------I am doing homework now.追问
怎么改,我不会改,不知道咋改,咋变!
追答你举个例子,我再告诉你,好吗
