Simple Past
FORM
Verb+ed or irregular verbs
Examples:
* You called Debbie. * Did you call Joana? * You did not call Lary.

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.
Examples:
* I saw a movie yesterday. * I didn't see a play yesterday. * Last year, I traveled to Japan. * Did you have dinner last night? * She washed her car.
We use the Simple Past to list a series of completed actions in the past. These actions happen 1st, 2nd, 3rd, 4th, and so on.
Examples:
* I finished work, walked to the beach, and found a nice place to swim. * Did you add flour, pour in the milk, and then add the eggs?
The Simple Past can be used with a duration which starts and stops in the past. A duration is a longer action often indicated by expressions such as: for two years, for five minutes, all day, all year, etc.
Examples:
* I lived in Brazil for two years. * Shauna studied Japanese for five years. * They sat at the beach all day. * They did not stay at the party the entire time.
The Simple Past can also be used to describe a habit which stopped in the past. It can have the same meaning as "used to." To make it clear that we are talking about a habit, we often add expressions such as: always, often, usually, never, when I was a child, when I was younger, etc.
Examples:
* I studied French when I was a child. * He played the violin.
The Simple Past can also be used to describe past facts or generalizations which are no longer true. As in USE 4 above, this use of the Simple Past is quite similar to the expression "used to."
Examples:
* She was shy as a child, but now she is very outgoing. * He didn't like tomatoes before.
