Introduzione

La voce passiva è usata più comunemente per:

• scritti formali o accademici; saggi, relazioni, articoli
• notizie: titoli, reportage.

Usiamo la voce passiva quando l'oggetto (persona o cosa) che subisce l'azione è più importante della persona o della cosa che compie l'azione, per esempio:

• The fire was started by Robin.

o quando non sappiamo chi o cosa ha compiuto l'azione:

• My car was stolen last night.

Forma

Formiamo la voce passiva con:
"be" + participio passato del verbo principale.

Il present simple passivo - esempi:

oggetto	Verbo "be"	Verbo principale	Complemento	Oggetto
The experiment	is isn't is not	carried out	every week	by scientists at the university.
The experiments	are aren't are not	carried out	every week.

Verbo "be"	oggetto	Verbo principale	Complemento	Oggetto
Are	the experiments	carried out	every week?

Il past simple passivo - esempi:

oggetto	Verbo "be"	Verbo principale	Complemento	Oggetto
The experiment	was wasn't was not	carried out	every week	by scientists at the university.
The experiments	were weren't were not	carried out	every week.

Verbo "be"	oggetto	Verbo principale	Complemento	Oggetto
Were	the experiments	carried out	every week?

La voce passiva può essere usata con qualsiasi tempo:

Oggetto (subisce l'azione)	Verbo "be" (vari tempi)	Verbo principale (participio passato)
The dogs	are	fed.
	are being
	were
	were being
	are going to be
	will be
	have been
	will be being
	have been being
	had been

Negli esempi qua sopra non sappiamo chi sta dando da mangiare ai cani. Non è importante. L'importante è che i cani stiano ricevendo del cibo.

Se vogliamo includere la persona o la cosa che compie l'azione, possiamo usare la preposizione "by":

• The dogs are being fed by a charity worker.

Passato

Passivo – The beds should have been made every day.

Punto di lingua avanzato

Ulteriori esempi della voce passiva:

• future perfect –
  The dogs will have been fed.
• future perfect continuous –
  The dogs will have been being fed.
• past perfect continuous –
  The dogs had been being fed.

Seppur grammaticalmente corretti, i tempi perfect continuous di solito non vengono usati al passivo. La situazione di solito non li richiede e suonano un po' strani.
