Perguntas frequentes

Qual é a diferença entre orações relativas restritivas e explicativas?

Uma oração relativa restritiva identifica exatamente de qual pessoa ou coisa se fala e não pode ser removida sem alterar o significado (ex.: "the book that I read"). Uma oração explicativa acrescenta informação extra sobre algo já identificado e é sempre separada por vírgulas (ex.: "her first novel, which won the prize"). Ao remover uma oração explicativa, o sentido principal permanece intacto.

Posso usar "that" em vez de "which" ou "who"?

"That" pode substituir "which" ou "who" apenas em orações relativas restritivas. Não pode ser usado em orações explicativas (após vírgula) nem diretamente após uma preposição. "The city in which I was born" é inglês formal correto, mas "the city in that I was born" está errado. Na fala informal, "that" é muito comum para pessoas e coisas em orações restritivas.

Quando devo usar "whom" em vez de "who"?

"Whom" é usado quando o pronome relativo funciona como objeto do verbo ou da preposição dentro da oração: "the person whom we hired" ou "the director to whom I reported". Na escrita formal e em exames como IELTS e TOEFL, "whom" é preferido. Na fala cotidiana, a maioria usa "who" em todas as posições, o que é amplamente aceito.

Como se forma uma oração relativa reduzida?

Para reduzir uma oração relativa ativa, remova o pronome relativo e o auxiliar e use o particípio presente (-ing): "the man who is waiting" → "the man waiting". Para orações passivas, remova o pronome relativo e o verbo "be" e use o particípio passado: "the form that was completed" → "the form completed". As orações reduzidas são comuns na escrita formal e acadêmica.

O que é uma oração relativa sentencial?

Uma oração relativa sentencial (também chamada de "relativa conectiva") usa "which" para se referir a toda a cláusula anterior, não apenas a um substantivo. Por exemplo: "She passed her exam, which surprised her parents." Aqui "which" se refere ao fato de ter passado — toda a situação. Esta estrutura é comum na escrita formal, não pode usar "that" e é sempre separada por vírgula.

A melhor forma de internalizar as orações relativas é ouvir inglês natural de forma extensiva.
