It is formed using 'was/were' + verb-ing. It is often used to describe an action that was interrupted by another action. * **Past Simple** tense is used to describe a completed action in the past. It is usually formed by adding '-ed' to the base form of the verb (for regular verbs), or using the past form of the verb (for irregular verbs). In these sentences, the past continuous tense is used to describe the ongoing action, while the past simple tense is used to describe the action that interrupted it or occurred at a specific moment.
