Explicação:

past perfect

Usamos o verbo to have (ter) na sua forma do passado, "had", como auxiliar, juntamente com o verbo principal conjugado na forma do Past Participle, que equivale ao nosso particípio.

simple past

O Simple Past é usado para indicar ações passadas já concluídas, que começaram e terminaram no passado, e com o acréscimo de –ed, –ied ou –d ao final do verbo principal no infinitivo.
