This document discusses the past simple and past continuous tenses in English. It provides information on the form, use, and time expressions for each tense. For the past simple, the form is the same for all persons and most regular verbs add "-ed" while there are many irregular verbs. It is used for finished past actions and past situations/habits. For the past continuous, the form is "was/were + verb + -ing" and it is used to express activities in progress before or after a time in the past, for descriptions, and interrupted/incomplete past activities. Both tenses can be used with time expressions like dates, times, and durations.
