About continuous aspect in this site British council>Continuous aspect, they say that continuous aspect can be used to describe something happening again and again. I don't really understand the example below:
They've been doing that every day this week.
As far as I know, in sentece above, present perfect continuous is for emphasizing action, and we could use present perfect simple if they want to emphasize the results instead. Am I correct? Do we have to use continuous aspect this sentence? Why?
Their next 2 example is using continuous aspect to talk about annoying/amusing habits (+always), and future habits (will be + V-ing). Are there any other situations that we use continuous to describe something happening again and again? If yes, what are they?
