INGLES

Passive Voice And Active Voice: La forma pasiva del verbo se construye tomando la parte deseada del verbo "to be" y añadiendo el participo del verbo principal. por consiguiente, el infinitivo activo de un verbo es, por ejemplo, "to sell" o "to buy" el infinitivo es "to be sold" o "to be brought". del mismo modo "it sells" ( activa) se transforma en "it is sold" (pasiva) 

 ESTRUCTURA

ACTIVA: SUJETO+VERBO ACTIVO+OBJETO+COMPLEMENTO 
por ejemplo: somebody discover america in 1492. 

PASIVA:SUJETO(OBJETO DE LA ACTIVA)+VERBO PASIVO+COMPLEMENTO

 
EJEMPLO: america was discovered in 1492 

EJEMPLO  ACTIVA: robert wrote many books last year 
la transformamos a pasiva: many books were written last year by robert 

en la voz pasiva no nos interesa el sujeto de la accion, cuando queremos mencionarlo en la pasiva usamos el "agente" con la preposicion BY
