The document is a review lesson for a Portuguese exam focusing on the use of can and the past continuous tense. It provides examples of can to request or give permission and its affirmative, negative and question forms. It then explains how the past continuous is formed using was/were + the -ing form of the verb and provides examples of its use along with short answers. It notes some spelling changes with verbs ending in e or y when adding -ing. It distinguishes between using the past continuous to describe an ongoing past action and the past simple to describe a completed action.
