In the Past
Use the past simple for activities which took place at a specified time in the past. This specific time is often stated through the use of a time expression such as 'ago'. However, the past simple is also used when the past time is understood from the context. All subjects take the same conjugation of the verb in the positive form. Negative and questions take the auxiliary verb 'did'. Regular verbs end in '-ed'.
