Use the Simple Past to express the idea that an action started and finished at a specific time in the past. Sometimes, the speaker may not actually mention the specific time, but they do have one specific time in mind. like "I saw a movie yesterday."
Past continuous, Use the Past Continuous to indicate that a longer action in the past was interrupted. The interruption is usually a shorter action in the Simple Past. Remember this can be a real interruption or just an interruption in time. like ' I was watching TV when she called. '
The Past Perfect expresses the idea that something occurred before another action in the past. It can also show that something happened before a specific time in the past.
We use the Past Perfect Continuous to show that something started in the past and continued up until another time in the past. "For five minutes" and "for two weeks" are both durations which can be used with the Past Perfect Continuous. Notice that this is related to the Present Perfect Continuous; however, the duration does not continue until now, it stops before something else in the past.
