La voz pasiva
Funciones de la voz pasiva
La voz pasiva se utiliza para mostrar interés por la persona o cosa que es objeto de una acción, en lugar de la persona o cosa que realiza dicha acción. Dicho de otro modo, la persona o cosa más importante pasa a ser el sujeto de la oración.
Ejemplos
- The passive voice is used frequently. (= nos interesa la voz pasiva, no quién la usa.)
- The house was built in 1654. (= nos interesa la casa, no quién la construyó.)
- The road is being repaired. (= nos interesa la carretera, no quién la está arreglando.)
En ocasiones empleamos la voz pasiva porque desconocemos o no queremos mencionar quién realizó la acción.
Ejemplos
- I noticed that a window had been left open.
- Every year thousands of people are killed on our roads.
- All the cookies have been eaten.
- My car has been stolen!
La voz pasiva suele utilizarse en textos formales. Cambiar a la voz activa hará que lo que escribes resulte más claro y fácil de leer.
