A voz passiva é utilizada para dar chamar mais atenção para o objeto que sofre a ação, e não para o sujeito. Ela é mais comum na escrita, e não é tão utilizada nos diálogos cotidianos.
Para realizar a transição da voz ativa para voz passiva o objeto da voz ativa deve assumir papel de sujeito da voz passiva.
O primeiro passo é identificar o objeto. O segundo passo é reconhecer a forma do verbo principal (estão indicados entre parênteses). O terceiro passo é adicionar o particípio passado do verbo principal.
