CARACTERISTICAS

1. Se dice que una oración está en VOZ ACTIVA cuando la significación del verbo es producida por la persona gramatical a quien aquél se refiere:
Pedro de Mendoza founded Buenos Aires.
(Pedro de Mendoza fundó Buenos Aires).

2. Se dice que una oración está en VOZ PASIVA cuando la significación del verbo es recibida por la persona gramatical a quien aquél se refiere:
Buenos Aires was founded by Pedro de Mendoza.
(Buenos Aires fue fundada por Pedro de Mendoza).

3. Se forma con el auxiliar del verbo to be y el participio pasado del verbo que se conjuga.

b) Tom was sent a book by Mr. Smith (pasiva idiomática). Esta estructura no es posible en castellano.
