The document discusses the past simple and past continuous tenses in English. It provides examples of how each is formed and the main uses of each tense. The past simple is formed with an -ed ending while the past continuous uses an -ing ending. The past simple is used to describe completed actions while the past continuous describes ongoing actions happening at the same time. Certain verbs like state of being, possession, senses and feelings are usually only used in the past simple, not continuous form. Time expressions are also provided to demonstrate when each tense is typically used.
