¿Cuándo usar Simple y cuándo usar Continuous?

Los hablantes nativos de inglés piensan en imágenes, no en palabras.

En general, cuando utilizamos lo simple, estamos hablando de hechos y en nuestra mente vemos una imagen estática.
Sin embargo, cuando utilizamos el continuo estamos hablando de la acción, y en nuestra mente podemos ver una imagen en movimiento.


Estático: The cat sat on the wall, looked at the birds and wagged its tail.

 

En movimiento: The cat was sitting on the wall looking at the birds and wagging its tail.

Cuando los hablantes nativos quieren describir acciones que son hábitos o rutinas fijas: cosas que no cambian, usamos Presente Simple.

Cuando los hablantes nativos quieren describir acciones que están sucediendo en este momento, o que terminarán pronto, usamos el Presente continuo.

When to use the simple and when to use the continuous?

However, when we use the continuous we are talking about the action, and in our minds we can see a moving image.


Static = The cat sats on the wall, looks at the birds and wags its tail.

Moving = The cat is sitting on the wall looking at the birds and wagging its tail.
