Question

Quais as formas possíveis da Question Tag se a declaração inicial for feita com um verbo não auxiliar?​

Answer 1

quando não tem nenhum tipo de verbo auxiliar (to be, to have perfeito ou verbos modais) então é porque a frase está no presente simples  OU passado simples e na forma afirmativa (já que na negativa viria o auxiliar do/does ou did na forma negativa), nesses casos sempre usa do/does pro presente e did pro passado.
