    modal perfect

    1- could you provide me with online reference that talks about present modal perfect and past modal perfect OR if possible, could you explain all their uses in detail. And when it turned to modal perfect progressive, do the uses change or they just add emphasis??

    2- what is the difference in meaning between event progressive and recurrent progressive?
    - im going grey (event)
    - im working with my uncle (recurrent)

    Re: modal perfect

    Are present modal perfect and past modal perfect the same as present perfect and past perfect?

    Re: modal perfect

    I was having conversation with a friend about this one.
    I hope this helps.

    A present practicable perfect.
    Most are formed by using “subject+ has or have+ verb+en.” Or “ed” ware en cannot apply.
    Experience:
    “ I have been to China before.”
    The speaker has been to China in the past but is talking about it now. If the speaker has been to China once, then they will always have had that experience in the past.

    Consequence
    “I have written my essay”
    They have written there essay in the past, but as a consequence that essay is still written or in existence to this very day. They might be telling someone about it a few days later.

    Past practicable
    Instead of ”has or have” the use of “had is applied.
    “I had written my essay”
    The speaker is speaking about the past but the action stays in the past. They had written the essay once and who knows what has happened to it since.
    “I had to do it” Refers to the past situation but doesn’t apply to anything that the present or future brings. Strictly in the past.

    Re: modal perfect

    Hi,
    I've never heard of present/past modal perfect.
    Let's take sth modal.
    You should do it. - with a simple infinitive, abt the present
    She may forget it.
    They must be kidding.

    You should have done it. -with a perfect infinitive, abt the past.
    She may have forgotten about it.
    They must have been kidding.


    Regards

    Re: modal perfect

    I may have done it vs I might have done it
    I will have done it vs I would have done it.

    2- what is the difference in meaning between event progressive and recurrent progressive?
    - im going grey (event)
    - im working with my uncle (recurrent)
    Going grey is a process, not a succession of events. In the second example, the work starts and stops, but does so repeatedly, while going grey doesn't start and stop, it just progresses over time.

    Re: modal perfect

    The uses change:
    He may have been killed = we don't know
    He might have been killed = he was in danger but survived
    Some speakers don't make this distinction, especially younger ones, so it may be on its way out.

    He will have done - future time reference or something we assume to have been completed now, though this second usage is BrE
    He would have done - past reference
