Present perfect and present perfect continuous I know I'm certainly not the first one to ask, but I have been struggling with present perfect and present perfect continuous for years now. I think I begin to understand, but some sentences are still such puzzles for me. So, you can say: - I have been struggling with present perfect and present perfect continuous for years (since it started in the past and has continued up until now) BUT, in that situation, you could also say: - I have struggled with present perfect and present perfect continuous for years AND - I have struggled with present perfect and present perfect continuous so far (since it's still at an unspecified time, even if "so far" refer to present) Am I wright or does "for" is fobidden with the present perfect? And why couldn't you say (or could you say): He has been working for this company for 3 years. (And he still works here) He has been working for this company for 3 years. (And he stops working for them somewhere in the past) Thank you!Sorry. I made a mistake. The second sentence should have been: He HAS WORKED for this company for 3 years.
