Explicação:

• Afirmativa: apenas o verbo no passado simples.
• Negativa: Auxiliar no passado (Did) + verbo no presente simples
• Interrogativa: Auxiliar no passado (Did) + verbo no presente simples  (*e nesse caso o auxiliar deve vir antes do sujeito)
• Verbo TO BE: Não precisa de auxiliar, porém é necessário inverter a ordem em interrogativas (to be antes do sujeito).

(** didn't é forma contraída: did + not)
