Voz passiva e voz ativa

Active and passive voice (The bomb has been planted)

Voz ativa = Eu lavei meu carro
Voz passiva = Meu carro foi lavado (Não tem sujeito; não se sabe quem levou)

Voz passiva serve para dar ênfase na ação e no objeto, reduzindo a importância do sujeito. A voz ativa faz o contrário.

Chefe: Já fez os relatórios?
Você: Os relatórios ainda não foram feito (Reduzindo a culpa do sujeito, você; ocultando a culpa)

Para converter voz ativa em passiva (ou vice-versa) é fundamental conhecer os tempos verbais.
