Past Simple: the simplest way to say something in the past!
USED: to express a completed action in the past, to describe a series of completed actions, to express habits in the past, and for stative verbs.
EXAMPLE: She worked yesterday.
Past Perfect: to describe an action finished before another past action, describe an action that happened before a specific time in the past, to describe cause and effect, to emphasize the result of an activity in the past.
EXAMPLE: She had worked yesterday and so she would not work today.
