Conforme evidenciado, a maioria dos verbos estava no passado simples (simple past) ou passado particípio (past participle).
Para saber quando usar cada tempo, reveja sua sentença: Ela é um passado que já acabou ou que de alguma ainda reflete no presente? No primeiro caso, use do simple past, e no segundo, use past participle.
Atenção: Apesar de uma parte considerável dos verbos ter a conjugação do simple past igual a do part participle, ainda existem alguns verbos que isso não é o caso. Atente-se a eles para não errar.
