Answer 1

Hola, la forma activa, se diferencia de la pasiva, en que la acción del verbo recae completamente en el sujeto( cuando es pasiva).
Te lo explico en un ejemplo:
The cover of a book is added after the book is written. En esta frase la acción del verbo, recae completamente en el sujeto.
La tapa del libro se añade después de que se escribe. Las pasivas,también siempre están acompañadas por el verbo ser (to be)
