Explicação:
Para passar as frases para a forma negativa, é preciso passar o verbo auxiliar para o negativo é o verbo principal para sua forma simples, tirando-o do tempo verbal no qual ele está. Por exemplo:
He did his homework. = He didn't do his homework.
E para passar as frases para a forma interrogativa, é preciso trocar o verbo auxiliar e o sujeito de lugar. Por exemplo:
He did his homework. = Did he do his homework?
