Explicación:
- El pasado continuo (past progressive) se utiliza para acciones que estaban pasando en un momento específico en el pasado. Se forma con el verbo auxiliar “to be” y el verbo+ing.
- El pasado simple (simple past) se utiliza para hablar de una acción concreta que comenzó y acabó en el pasado. En los verbos regulares, se forma con el infinitivo y la terminación “-ed”.
