Hello,
i do have some hesitations about the use of the present perfect.
1) For example, I come in a room, run into somebody, I want to ask him about is activity. I have to say "what are you doing ?" if he still does it and "what have you been doing ?" if he stopped (has stopped ?), right ? What's the différence with "What were you doing ?", I can't see anyone, both mean that he is not doing the activity anymore.
2) I come back home on the night and ask my wife about her activity of the day, should I say "what have you been doing today" or "what did you do today" ? I think i have to use the present perfect because today isn't finished yet but, actually, i'm not sure at all.
Thanks
