PASSIVE VOICE
La voz pasiva se utiliza cuando queremos darle mayor importancia a la acción y
no a quien la ha hecho.
For example
Voz Activa: They made this car in 1963.
Voz Pasiva: This car was made in 1963.
La voz pasiva se forma con el verbo auxiliar "to be" (ser/estar) y el participio
pasado del verbo.(Past Participle)
Subject + Verb To Be + Past Participle
The book was written by Susan
(El libro fue escrito por Susan)

Voz Pasiva Presente: Se utiliza cuando el verbo de la oración activa está
en presente.
Ejemplo:
Affirmative Form
(active) She reads the newspaper
(passive) The newspaper is read by her*
Negative Form
(active) She doesn’t read the newspaper
(passive) The newspaper isn’t read by her*

Voz Pasiva Pasada: Se utiliza cuando el verbo de la oración activa está
en pasado.
Ejemplo:
Affirmative Form
(active)
They wrote a letter
(passive) A letter was written by them*
Negative Form
(active)
They didn’t write a letter
(passive) A letter wasn’t written by them*
*Remember: Cuando usamos en las oraciones pasivas los pronombres (I, you,
she, he, it, we, they) tenemos que usar los Object Pronouns (me, you, her, him,
its, us, them)
Ejemplo: The door was painted by us (we)

PRESENT PERFECT
Qué es el Presente Perfecto?
El Presente Perfecto es usado para referirnos a una acción, evento o estado
que comenzó en un punto inespecífico en el pasado y que continua hasta el
presente o bien ha finalizado recientemente.
Ejemplo
I have lived in Santiago for 20 years
(Yo he vivido en Santiago por 20 años)
En simples palabras, “yo” ha vivido hace 20 años en Santiago. Sin embargo, no
se menciona desde cuando exactamente. Además, la oración indica que hata el
momento, "yo" sigue viviendo en la misma ciudad.
Uso del Presente Perfecto
Formamos el Presente Perfecto con:
El verbo "Have" que actúa como verbo auxiliar
Have: I, You, We, They
Has : He, She, It
Ejemplo
I have just done my homework
She has already finished her report
Mientras que el Verbo Principal debe estar en su forma Participia (3era
columna de de la lista de verbos irregulares y -ed para aquellos que son
regulares)
Ejemplo
I have just done my homework
(Yo he terminado mi tarea recién)
Affirmative Sentences:
Have / has + Past Participle form
Ejemplo: We have gone to the beach two times this month
