Present Perfect vagy P P Continous? Honnan tudom, hogy ide melyiket kell használni?

Azért mert a "have" ige birtokolni értelemben egy ún. "non-continous" ige. Nem használjuk a folyamatos alakját ebben az értelmezésében, ennek megfelelően a folyamatos igeidőket sem.

Igen, a linkelt oldal jól elmagyarázza, hogy mikor lehet folyamatos igeidőknél használni a have igét és mikor nem:

I have a dollar now. Non-Continuous Verb

I possess a dollar.

I am having fun now. Normal Verb

I am experiencing fun now.

It is important to remember that Non-Continuous Verbs cannot be used in any continuous tenses. Also, certain non-continuous meanings for Mixed Verbs cannot be used in continuous tenses. Instead of using Present Perfect Continuous with these verbs, you must use Present Perfect.

Examples:

Sam has been having his car for two years. Not Correct

Sam has had his car for two years. Correct
