Present perfect tense

[gmatlive]

This sentence is from SC Guide.

We HAVE LIVED in a hut for three days.

"This sentence means that we started living in the hut three days ago and that we are still living in that hut."

I know present perfect could indicate a continued action or effect. Does it really indicate that "we are still living in that hut".

In that case, how different is it from - We have been living in a hut.

[tim]

"have lived" indicates that it is something that has happened, i.e. it happened but may not be finished for good. maybe we lived there last year and will again in the future. "have been living" conveys a much stronger sense that we are currently living there right now. you aren't likely to see this distinction on the GMAT though, so i wouldn't worry about it..
