This document outlines the differences between the past simple and past continuous tenses in English. It discusses their formation, uses, and connecting patterns using words like "when", "while", and "as". The past simple is used for completed actions, actions that happened once or several times, or actions that occurred one after another. The past continuous is used for actions that were ongoing or happening at a specific time in the past. It provides examples of sentences using both tenses alone and in combination with connectors.
