Explicação:
Quando usamos a partícula "did" para perguntas (no passado. Por exemplo "você fez a lição?"), no inglês, o verbo volta ficar no infinitivo (sem estar no passado, presente, futuro), porque o did no começo da pergunta já faz a tarefa de deixar a pergunta no tempo passado.
Ex.:
You washed the dishes.
(Você lavou a louça)
Did you wash the dishes?
(você lavou a louça?)
