Question

Explicacion de passive y active voice

Answer 1

Hola formación: 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) tambien te doy la estructura: voz activa: SUJETO+VERBO ACTIVO+OBJETO+COMPLEMENTO por ejemplo: somebody discover america in 1492. voz pasiva:SUJETO(OBJETO DE LA ACTIVA)+VERBO PASIVO+COMPLEMENTO por ejemplo:america was discovered in 1492 otro ejemplo de 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 aqui te dejo un cuadro de los cambios verbales de la voz activa y pasiva: activa: he sells books he is selling books he sold books he was selling books he has sold books he has been selling books he had sold books he had been selling books he will sell books he will be selling books pasiva books are sold books are being sold books were sold books were being sold books have been sold books have been being sold books had been sold books had been being sold books wil be sold books will be being sold
