The Present Perfect form - Year 3

Come costruiamo il Present Perfect Tense?



La struttura del present perfect tense è:


 SOGGETTO+      VERBO AUSIL. AVERE     +     PARTICIPIO PASSATO DEL
    VERBO PRINCIPALE




    
     
Esempi:


subjectauxiliary verbmain verb
+IhaveseenET.
+Youhaveeatenmine.
-Shehasnotbeento Rome.
-Wehavenotplayedfootball.
?Haveyoufinished?
?Havetheydoneit?



Contrazioni con il present perfect:

Quando si usa il present perfect tense di solito si contrae il soggetto ed il verbo ausiliare. 

I haveI've
You haveYou've
He has
She has
It has
John has
The car has
He's
She's
It's
John's
The car's
We haveWe've
They haveThey've


Esempi:
  • I've finished my work.
  • John's seen ET.
  • They've gone home.

Il participio passato:

  • Se il verbo è regolare, aggiungi un -ed alla forma base.   -   esempio: play - played.     Attenzione alle regole di sscrittura, le stesse usate per il simple past: study - studied, stop - stopped, love - loved.
  • Se il verbo è irregolare, devi impararlo a memoria!  -  esempio: go - gone ; be - been...
