Step-by-step explanation:
In the active voice, the subject of the sentence is also the performer of the action being described by the verb. Take a look at the example below:
- Gina told me a secret.
In the sentence above, the action described by the verb "told" is performed by the subject Gina. The direct object, what was told, is the "secret". The indirect object, the one who listened, is "me".
To make the passive voice of the sentence above, we can transform either the direct object or the indirect object into the subject. Now, "Gina" will no longer be a subject, but only an agent. The verb structure will change with the addition of the auxiliary "be":
- I was told a secret by Gina.
- A secret was told by Gina to me.
