16. Passive Voice

When rewriting active sentences in passive voice, note the following:
  • The object of the active sentence becomes the subject of the passive sentence
  • The finite form of the verb is changed (to be + past participle)
  • The subject of the active sentence becomes by Agent in the passive sentence (or is dropped)
  • Only active sentence containing object which can be changed into passive form
  • The two forms should have the same tenses
  • IN A PASSIVE CLAUSE, WE USUALLY USE A PHRASE BEGINNING WITH BY IF WE WANT TO
MENTION THE AGENT - THE PERSON OR THING THAT DOES THE ACTION, OR THAT CAUSES WHAT HAPPENS.
EXAMPLES:

MY MOTHER   MAKES   THE SANDWICH EVERY MORNING.
   SUBJECT     VERB1+S/ES              O     C (ADV. OF TIME)


THE SANDWICH  IS MADE  BY MY MOTHER EVERY MORNING.
SUBJECT    O BE+V3          AGENT                C (ADV. OF TIME)
  • If you want to change an active sentence which has two objects into its passive forms, there are two ways:
  • Make its indirect object into the subject of the passive sentence.
  • Make its direct object into the subject of the passive sentence
WHAT ABOUT OTHER TENSES?
PRESENT CONTINUOUS : [ S + TO BE + BEING +V3 (PAST PARTICIPLE)
PRESENT PERFECT: [ S + HAS/HAVE + BEEN + V3 (PAST PARTICIPLE
Here are the examples:
  • A young boy is catching a butterfly.
  • A butterfly is being caught by a young boy.
  • Yano has returned the book to the library.
  • The book has been returned to the library by Yano.
John  is giving  his girl-friend  a bunch of flower.
                                    indirect object      direct object
Passive: The indirect object as the subject
                John’s girl-friend is being given a bunch of flower
or
Passive: The direct object as the subject
                A bunch of flower  is being given  to John’s girl-friend

Take a look at the followings :
  • People don’t use bikes anymore
  • Bikes are not used anymore
  • Did the students play the cards in the class yesterday?
  • Were the cards played in the class yesterday?
  • And so on
