have sat/ have been sitting

[dewedfrost]

Hello!I would like to have some advice, please! In the following sentence I have to choose the right verb form:
"You HAVE DRUNK/ HAVE BEEN DRINKING three coffees since I HAVE SAT/ HAVE BEEN SITTING here." (from a grammar exercise)
I'd say HAVE DRUNK - HAVE SAT. Do you agree? Thanks a lot in advance!

sorry, I've forgot "three coffees"!!!

 

[dewedfrost]

Thanks, Piscean, but I've forgot tu put "three coffees": what would you suggest now? Many thanks again!

You have drunk three coffees in the time I've been sitting here.

 

[emsr2d2]

If the other person has finished their third coffee, I would say "You have drunk three coffees while I've been sitting here."

I find the use of "since" with the perfect continuous rather unnatural. If I wanted to use "since", I would say "You have drunk three coffees since I sat down".

 

[dewedfrost]

Thank you so much, emsr2d2, piscean and Barb_D! I suppose there must an error in the text of the exercise! :-D

:up: (It's not in the spirit of the exercise, as it avoids the use of a verb [a good way of not making mistakes, if you can get away with it ], but in many contexts, rather than 'You have drunk three coffees', you could just say 'That's your third!')
