Still raining.
>3. It has been raining.
Could refer to what's been happening in a given period of time; it
might not be raining at that precise moment.
>4. She's been playing tennis since eight.
Presumably still playing.
>5. Have you been working hard?
Could refer to a general condition (i.e., one could ask this of
someone when they have already gone home for the day).
