Past Simple vs Past Continuous — cuándo usar cada uno (con ejemplos)

La diferencia entre I worked y I was working, explicada con la lógica que los hispanohablantes ya conocen del español. Con test final.

La buena noticia: ya conoces esta lógica

El español distingue exactamente lo mismo:

  • Trabajé ayer. → I worked yesterday. (Past Simple — acción terminada)
  • Estaba trabajando cuando llamaste. → I was working when you called. (Past Continuous — en progreso)

Si dominas indefinido vs imperfecto progresivo en español, el 80% del trabajo está hecho. Solo falta la forma.


Past Simple — la foto terminada

Forma: verbo + -ed (regulares) o segunda columna (irregulares)

Usa Past Simple para:

1. Acciones completadas en un momento concreto:

  • She arrived at 9. (llegó — hecho terminado)
  • We watched a film last night.

2. Secuencias de acciones (una tras otra):

  • I woke up, had breakfast and left for work.

3. Periodos cerrados:

  • I lived in Madrid for five years. (ya no vivo allí)

Past Continuous — la película en marcha

Forma: was/were + verbo-ing

Usa Past Continuous para:

1. Acción en progreso en un momento del pasado:

  • At 8pm, I was having dinner. (estaba cenando — en medio de la acción)

2. Acción de fondo interrumpida por otra:

  • I was sleeping when the alarm went off.

3. Dos acciones largas simultáneas:

  • While I was cooking, he was setting the table.

4. Ambientar una historia:

  • The sun was shining and the birds were singing...

La combinación estrella: when y while

La estructura más examinada — acción larga + acción corta:

[Past Continuous] when [Past Simple]

  • I was walking home when it started to rain.

While [Past Continuous], [Past Simple]

  • While she was studying, someone knocked at the door.

Truco: when suele introducir la acción corta (Past Simple); while la larga (Past Continuous).


Errores típicos de hispanohablantes

❌ When I was arriving home, I saw him. ✅ When I arrived home, I saw him. (llegar es puntual, no progresivo)

❌ I was knowing the answer. ✅ I knew the answer. (know, want, like, understand — verbos de estado, no van en continuous)

❌ Yesterday I was going to the gym. (como acción completada) ✅ Yesterday I went to the gym.
