The document provides information about using the past continuous and simple past tenses in English. It explains that the past continuous describes an ongoing action in the past, and is formed using was/were plus the present participle. The simple past describes a completed action, and is formed using the base form of the verb. Examples are provided to illustrate using each tense to talk about actions that occurred at specific times in the past. The document also discusses how to combine the past continuous and simple past using words like "while" and "when" to connect two related actions, one ongoing and one completed.
