[General] I've worked here for four years.

[manikanth]

I've worked here for four years.

the above line gives the meaning of i am working even now also from past 4 years? Whether it represents unfinished/finished past action?

 

[MikeNewYork]

It does not represent past action. The action is ongoing.

 

[manikanth]

It does not represent past action. The action is ongoing.

Then what is the difference between I've worked here for four years.
and I've been worked here for four years.

 

[Matthew Wai]

I've been worked here for four years.

I would replace 'worked' with 'working', but I am not a teacher.

 

[MikeNewYork]

"I've been worked here for four years" is not grammatical. See Matthew's post.

 

[Barb_D]

There is no difference between "I've been working here" and "I've worked here" in terms of whether it's still going on. There may be a difference in mindset, with the progressive POSSIBLY feeling newer or temporary or less likely to continue.

 

[manikanth]

"I've worked here" - The action is ongoing
"I've missed my flight" - It seems the action was completed

Both seems to be same structure (present perfect). if both actions is right, then how we distinguish which is finished and unfinished action?

 

[Matthew Wai]

I think the action has finished in 'I have read the book', but I am not a teacher.

 

[MikeNewYork]

Manikanth, you left off "for four years". Can you say "I've missed my flight for four years?"

 

[Matthew Wai]

Can the action be complete in 'I've worked here for years but now I have to quit'?

 

[tedmc]

The four years of working is complete. Quitting now or not is another issue.

 

[Matthew Wai]

When I wrote 'complete', I meant the action is no longer ongoing.

Not a teacher.

 

[MikeNewYork]

"I have worked there for four years" does not preclude working there tomorrow or for four more years.

 

[Matthew Wai]

Assuming I am packing my belongings instead of working at the moment and will quit immediately, may I say 'I have worked here for four years'?

 

[MikeNewYork]

Yes. The present perfect says nothing about the future.
