Past sentence

Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.
Example: My bike was stolen.
In the example above, the focusis on the fact that my bike was stolen. I do not know, however, who did it.
Sometimes a statement in passive is more polite than active voice, as the following example shows:
Example: A mistake wasmade.
In this case, I focus on the fact that a mistake was made, but I do not blame anyone (eg. You have made a mistake.).
Form of Passive
Subject + finite form of to be + Past Participle
Example: Aletter was written.
When rewriting active sentences in passive voice, note the following:
* the object of the active sentence becomes the subject of the passive sentence
* the finite form of theverb is changed (to be + past participle)
* the subject of the active sentence becomes the object of the passive sentence (or is dropped)

El uso de pasivo
La voz pasiva se utiliza cuando laatención se centra en la acción. No es importante o no sabe, sin embargo, ¿quién o qué está realizando la acción.
Ejemplo: Mi moto era robada.
En el ejemplo anterior, la atención se centra en el hecho deque mi moto era robada. No sé, sin embargo, que lo hizo.
A veces, una declaración en la pasiva es más cortés que la voz activa, como muestra el siguiente ejemplo:
Ejemplo: Se cometió un error.
