Basic Rules of Changing Active Voice into Passive Voice

     

    What is Voice?

    The voice of a verb tells whether the subject of the sentence performs or receives the action.

    Types of Voice:

    Active Voice: the subject performs the action expressed by the verb.

    Usage: when more clarity and straightforward relation is required between verb and subject.

    Passive Voice: the subject receives the action expressed by the verb.

    Usage: when the action is the focus, not the subject or when the doer is unknown.

    Example:

    Active Voice: Someone will serve refreshments.
    Passive Voice: Refreshments will be served by someone.

     

    Rules of Conversion from Active to Passive Voice:

    1. Identify the subject, the verb and the object: S+V+O
    2. Change the object into subject
    3. Put the suitable helping verb or auxiliary verb
    4. Change the verb into past participle of the verb
    5. Add the preposition “by“
    6. Change the subject into object
