So, what is the difference between Present Perfect Continuous and Present Perfect, when it comes to actions started in the past and continuing in(to) the present?
This time we are going to talk about biographical facts. These are the components:
1. Action started in the past
2. Action continues in(to) the present
3. We have indication of duration: for / since or their synonyms, or we can infer the fact of duration from the context.
Biographical facts: Either Present Perfect Continuous or Present Perfect
I have been living / working here for 20 years
I have lived / worked here for 20 years
I have lived / worked here since 1970
I have been living / working here since 1970
So, what is the difference? When it comes to these 3 verbs live, work and also study, I don’t really see a difference. So, to which category do we refer this rule? What is common about these “work live and study”? I think we can call it biographical facts. Definitely, we can find more verbs describing biographical facts, but live, work and study are just most common.
I’ve played computer games most of my life
It’s the same as this:
I’ve been playing computer games most of my life
I hope it’s clear now. So, we are done!
