John wrote the letter.

Consideremos a frase seguinte na voz ativa (active voice):

( João escreveu a carta.)

S VC

Para convertê-la na voz passiva (passive voice), siga as quatro etapas seguintes:

(a) o objeto direto the letter na voz ativa passa a ser o sujeito na voz passiva;

(b) o verbo auxiliar be (no mesmo tempo em que se encontra o verbo wrote ) é adicionado na voz passiva;

(c) o verbo wrote na voz ativa vai para o particípio passado na voz passiva;

(d) o sujeito John na voz ativa vai para a voz passiva como agente da voz passiva precedido pela preposição by .

The letter was written by John. (A carta foi escrita por João.)

Mais exemplos:

They sell flowers.

Flowers are sold (by them) (1).

Eles vendem flores.

Flores são Vendidas.

ou

Vendem-se (2) flores.

Peter made an offer.

An offer was made by Peter.

Pedro fez uma oferta.

Uma oferta foi feita por Pedro.

The shop will deliver the parcel.

The parcel will be delivered by the shop.

A loja entregará o embrulho.

O embrulho será entregue pela loja.

(1) como se desconhece o agente da ação they, a expressão by them é

aqui irrelevante e poderia ser removida.

(2) em português, o verbo reflexivo é por vezes empregue em vez da voz

passiva.

Consideremos a frase seguinte na voz passiva (passive voice):

The letter was written by John. (A carta foi escrita por João.)

Para convertê-la para a voz ativa (active voice), siga as três etapas

seguintes:(a) O agente John da ação written na voz passiva passa a ser o sujeito na

voz ativa;

(b) O verbo principal written (no particípio passado na voz passiva) vai para o

mesmo tempo em que o verbo auxiliar be se encontra;

(c) O sujeito the letter na voz passiva passa a ser o objeto direto na voz ativa.

John wrote the letter. (João escreveu a carta.)

Mais exemplos:

Books are sold.

They (1) sell books.

Vendem-se livros.

Eles vendem livros.

She was arrested yesterday by the police.

The police arrested her yesterday.

Ela foi presa ontem pela polícia.

A polícia prendeu-a ontem.

The car has been stolen.

Somebody (2) has stolen the car.

O carro foi roubado.

Alguém roubou o carro.

The problem is going to be solved by Jane.

Jane is going to solve the problem.

O problema vai ser resolvido por Joana.

Joana vai resolver o problema.

Entende-se que:

(1) o pessoal da livraria(2) o ladrão

A voz passiva (passive voice) forma-se da seguinte maneira:

Verb To be + Verb (Past Participle)

Onde BE = verbo auxiliar (ser/estar)

e PAST PARTICIPLE = verbo principal no particípio passado (pp)

Exemplos:

Present Simple am/is/are + (pp) Books are sold here.

Present Continuous am/is/are being + (pp) The car is being repaired.

Present Perfect Tense has/have been + (pp) The car has been stolen.

Past Simple was/were + (pp) She was arrested yesterday.

Past Continuous was/were being + (pp) The car was being repaired.

Past Perfect Tense had been + (pp) The car had been stolen

Future Simple will be + (pp) The parcel will be delivered.

Future Perfect Tense will have been + (pp) All the documents will have been

signed by Friday.

Future going to am/is/are going to be + (pp) The problem is going to be solved.

Modals (present) can/may/etc. be + (pp) The exercise can be done.

Modals (past) could/might/etc. have been + (pp) He could have been killed.

Infinitive to be + (pp) The job needs to be done.

Os tempos verbais seguintes são raramente empregues na voz passiva devido à

falta de boa sonância:

Present Perfect Continuous

Past Perfect Continuous

Future Continuous

Future Perfect Continuous

has/have been being + (pp)

had been being + (pp)

will be being + (pp)

will have been being + (pp)

Consideremos as duas frases seguintes com dois objetos: direto e indireto

na voz ativa (active voice).

John gave me a book. (João deu-me um livro.)

Onde:John = sujeito

gave = passado do verbo give

me = complemento (objeto indireto)

a book = complemento (objeto direto)

John gave a book to me.

John = sujeito

gave = passado do verbo give

a book = complemento (objeto direto)

to = preposição

me = complemento (objeto indireto)

(João deu um livro a mim.)

Para converter qualquer uma das frases anteriores em voz passiva

(passive voice), há duas formas de se fazer:

(a) Objeto indireto me como sujeito (I) :

I was given a book (by John).

(b) Objeto direto a book como sujeito:

A book was given to me (by John).

OBS.: A forma (a) é normalmente a mais comum entre as duas.
