1. Regra Geral: Para passar uma oração para a voz passiva, coloca-se o verbo to be no
mesmo tempo verbal do verbo principal da oração na ativa, que é necessariamente
passado para o particípio.
Isto é, voz passiva é:
Simple Present:
am / is / are (not)
Simple Past:
was / were (not)
Future:
will be
Present Continuous:
is / are being + PARTICIPLE
Past Continuous:
was / were being ex: done, taken, grow, etc.
Conditional:
would / may be
Present Perfect:
has / have been
Past Perfect:
had been
Lista de transformações:
Voz ativa
writes (simple present)
is / are written
wrote(simple past)
was / were written
was / were writing (past continous)
was / were being written
have / has written (present perfect)
has / have been written
had written (past perfect)
had been written
would write (conditional)
•They
Voz passiva
would be written
will write that letter. (Eles escreverão aquela carta).
That letter will be written by them. (Aquela carta será escrita por eles).
Note que ambas as orações são compostas da seguinte forma:

2. Sujeito+Verbo+Objeto, e o que é objeto em uma é sujeito na outra.
Somebody cleans the office every day. (Alguém limpa o escritório todo
dia).
The office is cleaned every day. (O escritório é limpo todo dia).
Note a mudança do verbo: na oração na voz ativa o verbo se encontra apenas
no Simple Present, já na voz passiva existe uma locução verbal entre o verbo to
be no presente e o verbo principal clean no particípio cleaned.
•Somebody cleaned the office yesterday. (Alguém limpou o escritório
ontem).
The office was cleaned yesterday. (O escritório foi limpo ontem).
O
mesmo
exemplo,
porém
no
passado.
•People have watched the World Cup. (As pessoas assistiram à Copa do
Mundo).
The World Cup have been watched. (A Copa do Mundo foi assistida – veja
que, no português padrão, não existe a forma passiva dessa oração, já que o
verbo
assistir,
nesse
contexto,
é
transitivo
indireto).
Note, que neste caso não há necessidade de inserir “by people” (pelas pessoas)
na
voz
passiva.
•Picasso
painted
“Guernica”.
(Picasso
pintou
“Guernica”).
“Guernica” was painted by Picasso. (“Guernica” foi pintada por Picasso).
•South Africa produces about half of the world’s gold. (A África do Sul
produz
cerca
de
metade
do
ouro
do
mundo).
About half of the world’s gold is produced by South Africa. (Cerca de
metade do ouro do mundo é produzida pela África do Sul).
•Anyone can plant a tree. (Qualquer um pode plantar uma árvore).
A tree can be planted by anyone. (Uma árvore pode ser plantada por
qualquer
um).
•Shakespeare wrote “Romeo and Juliet”. (Shakespeare escreveu “Romeu
e
Julieta”).
“Romeo and Juliet” was written by Shakespeare. (“Romeu e Julieta” foi
escrito
por
Shakespeare).
•Somebody is painting the door. (Alguém está pintando a porta).
The door is being painted. (A porta está sendo pintada).
verbo to be (no mesmo tempo em que estava o verbo da voz
ativa) + Past Participle (do verbo da ativa)
Ex.:
Voz ativa: Jane writes a letter.
Voz passiva: A letter is written by Jane.

3. Active: Susan closed the door.
Passive: The door was closed by Susan
1. O Complemento directo (the door) na frase activa
corresponde ao sujeito na frase passiva
2. O sujeito (Susan) na frase activa corresponde na passiva ao
agente da passiva que é sempre introduzido pela
preposição by.
3. A passiva forma-se com o verbo to be (no tempo do verbo
principal da frase activa) + o particípio passado do verbo
principal.
4. A penas os verbos transitivos, ou seja, aqueles que exigem
um complemento directo e / ou indirecto, podem ser
colocados na voz passiva.
5. O agente da passiva é omitido quando o sujeito da activa é
indefinido, vago, desconhecido, impessoal ou óbvio, sendo
normalmente designado na activa por one, they, you,
somebody, nobody, everyone, etc.
