[Grammar] The present perfect continuous: I have been working all day.

[Matthew Wai]

1. I have been working all day, and I am still busy now.
2. I have been working all day, and I am having a rest now.

#1 and #2 denote a continuing action and a finished action respectively.
Am I right or wrong?

 

[teechar]

In #1, you could be busy with a different action now. Try:
I've been working all day, and I haven't finished yet.

In #2, you could be just having a short break, which would mean that you'll get back to your work later. Try:
I've been working all day, but I'm finished now.

 

[Matthew Wai]

The present perfect continuous could refer to 'ACTIONS THAT HAVE JUST FINISHED, BUT WE ARE INTERESTED IN THE RESULTS'── quoted from http://www.edufind.com/english-grammar/present-perfect-continuous/
