UNIT 2 – Clases de inglés gratis PET/B1



The past simple is used to describe:

  • Actions or events in the past:
  • I went to London last year.
  • Actions or events which happened one after another:
  • I visited the Prado museum and later went to a cafeteria. 

The past continuous is used to describe:

  • Activities that were already happening at a moment in the past:
  • While I was walking to college, I met a friend.
  • Activities in which we don’t know the start or the finish: 
  • The music was playing and I was feeling happy. 

The past simple and past continuous are often used to show that an action happened in the middle of an activity:

We were watching tv when the phone rang. 

When, while and as

  • We can use when, while and as to introduce an activity in the past continuous: when/while/as I was watching tv the phone rang.
  • We generally use when to introduce actions in the past simple: I was watching tv when the phone rang. 


1.- Past simple

El “past simple” describe una acción pasada ya finalizada.

When I was young I lived in Madrid (ahora vivo en Barcelona)

2.- Past continuous

Indica que una acción se estaba desarrollando en cierto momento del pasado al cual se hace referencia. No dice si la acción ya finalizó o todavía continuaba

When the mother came home her husband was playing with the kids (no sabemos si terminó de jugar en ese momento o continuó jugando)

A veces se describen dos acciones simultáneas que tuvieron lugar en el pasado. En dicho caso, se utiliza el “past  simple” para describir aquella que finalizó y el “past continuous” para aquella otra que estaba ocurriendo cuando la primera tuvo lugar.

Yesterday evening when you called me I was having a shower

When the parents arrived home the children were watching TV

Otra diferencia entre ambos tiempos es que el “past continuous” se utiliza a veces para indicar que la acción es más casual, menos planificada.

Yesterday morning, from 8 to 10, I was running (algo rutinario, que suelo hacer con frecuencia, por lo que no lo resalto)

Yesterday morning, from 8 to 10, I ran (algo diferente, un tanto extraordinario, por lo que quiero destacarlo)

Used to

We use used to, to describe things that happened regularly in the past but don’t happen now:

Used to, is only used in the past. I used to live in Dublín but now I live in Barcelona.

  • To talk about things that happen regularly in the present, use the present simple.
