Como ya hemos visto en el simple present, se forma el tiempo continuo que corresponde con to be. Es lo mismo con el simple past sólo que en este caso hay que utilizar el simple past del verbo to be.

ejemplo
Forma de 'to be' + verbo pleno + Redoblamiento
de la consonante
+ sufijo -ing = past continuous

we were sell ing we were selling
you were wait ing you were waiting
they were write ing they were writing
