When do we use present perfect continuous to express an action that just have finished?
We never know it’s finished until it is not done any more. If you use the continuous, you are still potentially in the process.
So, he’s been hunting for 2 hours implies he is still doing it?
Yes.
And if it’s just finished, we will have to use present perfect?
Yes.
Thank you master.
