Voz Passiva - Verbos Preposicionados

Construção da voz passiva com verbos que exigem preposições

- Os objetos de verbos que exigem preposições (look at, listen to, pay for, etc) podem tornar-se o sujeito em construções passivas. Observe os exemplos:

We have looked at the plan carefully. (active voice)
                            (objeto)

The plan has been carefully looked at. (passive voice)
(suj.)

Nobody listens to her. (active voice)
                           (obj.)

She is never listen to. (passive voice)
(suj.)

Somebody has paid for your meal. (active voice)
                                     (objeto)

Your meal has been paid for. (passive voice)
(sujeito)

Atente para a ordem das palavras (word order); a preposição não pode ser suprimida.

I don't like to be shouted at. (NOT I don't like to be shouted.)

- Se já há objeto direto na oração, o segundo objeto (objeto preposicionado), que vem depois da preposição, não pode transformar-se em sujeito na voz passiva:

They threw stones at him. (active voice)
                 (o. d.)    (o. p.)

Stones were thrown at him. (passive voice)
(suj.)
(BUT NOT He was thrown stones at.)

They stole a bicycle from him. (active voice)
                  (o. d.)         (o. p.)

A bicycle was stolen from him. (passive voice)
(sujeito)
(BUT NOT He was stolen a bicycle from.)

They poured water on us. (active voice)
                   (o. d.)   (o. p.)

Water was poured on us. (passive voice)
(suj.)
(BUT NOT We were poured water on.)

Observe que pronomes e substantivos possessivos também não podem tornar-se sujeito na voz passiva:

They called Mr. Peteron's name. (active voice)

Mr. Peterson's name was called. (passive voice) (BUT NOT Mr. Peterson was name called.)

I broke her mirror. (active voice)

Her mirror was broken. (passive voice) (BUT NOT She was mirror broken.)
