GRAMMAR - THEORY: PASSIVE VOICE

1. USE

We use the passive voice when we are interested in the OBJECT / PROCESS, not the performer.

We place “by + performer” at the end of a passive voice sentence if we want to include in the passive voice sentence the subject of the active sentence.

Examples

“Somebody stole my bike” → “My bike was stolen”.  
“Tom stole my bike” → “My bike was stolen by Tom”.  


2. FORM: TO BE + PAST PARTICIPLE (-ED/3rd COLUMN, IRREGULAR VERBS)

THE OBJECT of the active voice sentence becomes the SUBJECT in the passive voice sentence.

Examples:

Active
Mary
buys
a car.
SIMPLE PRESENT

Passive:
A car
is bought
by Mary.


Active:
Mary
bought
a car.
SIMPLE PAST

Passive:
A car
was bought
by Mary.


Active:
Mary
has bought
a car.
PRESENT PERFECT

Passive:
A car
has been bought
by Mary.


Active:
Mary
will buy
a car.
WILL-FUTURE

Passive:
A car
will be bought
by Mary.


Active:
Mary
can buy
a car.
MODALS

Passive:
A car
can be bought
by Mary.


CONTINUOUS TENSES AND THE PASSIVE FORM

  • Present Continuous Passive: Is/am/are + being + past participle (The house is being painted).
  • Past Continuous Passive: Was/were + being + past participle (The cars were being washed).
  • Attention - Neither Future Continuous nor Perfect Continuous tenses use the Passive Voice because putting together two forms of the "be"together sounds awkward, so use simple passive forms instead.


    3. PASSIVE VOICE: THE TWO GRAMMAR STRUCTURES

    When verbs like believe, consider, expect, know, think, say, suppose are used in the Passive Voice, there can be structured in two ways: an impersonal option and a personal option, which is more frequent than the impersonal one.

    Option 1 (Impersonal Construction): Starts with a dummy "It" + passive verb + that-clause.

    It + is/was [passive verb] + that + subject + verb...

    Everybody thinks that Elena is really talented at French.
    It is thought (that) Elena is really talented at French. ("Se piensa...")

    Option 2 (Personal Construction): Starts with the real subject + passive verb + to-infinitive.

    Subject + is/was [passive verb] + to + infinitive...

    Everybody thinks that Elena is really talented at French.
    Elena is thought to be really talented at French. ("Se piensa que Elena...")

    4. PASSIVE VOICE SENTENCES WITH TWO OBJECTS

    The INDIRECT OBJECT of the active voice sentence can become the SUBJECT in the passive voice sentence. Translation into Spanish: "A ... le/les..." / Active voice: "Subject + V"

    I- If the active voice follows the order “Subject + Verb + Direct Object + to Indirect Object” → Omit “to”:

    “Helen offered a job to my brother Jim 
    becomes 
    My brother Jim was offered a job by Helen”


    “Dan will give a present to Jane 
    becomes 
    Jane will be given a present by Dan”


    II- If the indirect object of the active sentence is an object pronoun → Transform it into a subject pronoun:

    “Mary offered a job to himbecomesHe was offered a job by Mary”


    “Dan will give a present to her becomes She will be given a present by Dan”

    5. I. THE CAUSATIVE STRUCTURE:"HAVE/GET SOMETHING DONE"

    To describe situations where we want someone else to do something for us. It highlights the task itself completed, especially when the person doing it is not even named. 

    - Have something done: It is a more formal structure than “get something done”.

    - Get something done: It is more informal and most common in spoken English.

     Examples:

    I had /got my computer repaired yesterday. He will have /will get his hair cut soon.

    5. II. THE ACTIVE CAUSATIVE STRUCTURE
        "HAVE SOMEONE DO SOMETHING/ GET  SOMEONE TO DO SOMETHING"

    It highlights WHO performs the action. Differences in meaning between the use of both forms:

    Have someone do something: Commission, pay, ask, arrange.

    Get someone to do something: Convince, persuade.


    Other variations of the active causative structure:

    Make someone do something: Force, compel.
    Let someone do something: Allow, permit.

    Examples:

    I had my brother repair my computer yesterday. 

    He will get his mum cut his hair soon.

    The teacher made the pupils do the project.

    My dad lets me go to your birthday party.
