Preterite vs Imperfect

I can choose past viewpoint and tell a short story using both preterite and imperfect.

What you will learnHow to choose event versus background viewpoint and combine both in a short past narrative.
What you are learningOne new connector, an interruption pattern, and three meaning-sensitive past-viewpoint contrasts.
How to know you're readywithout help new-situation choice and storytelling; Reveal remains support and never counts as doing it without help.
Lesson 1

Event vs Background

What you are learning:I can understand the event-versus-background relationship between preterite and imperfect.

English comparison: Spanish chooses a past viewpoint. The preterite typically presents a completed event seen as a whole; the imperfect presents ongoing, habitual, descriptive, or background information. This is not a simple “completed versus incomplete” rule.

pattern teaching · no new vocabulary
hablé
I spoke — completed-event viewpoint
hablaba
I was speaking / used to speak — background or habitual viewpoint
Both forms were already learned before Module 43. This lesson teaches how viewpoint changes the role they play in a story.
