                                  THE PASSIVE
What is meant by the active and the passive voice?
The terms active voice and passive voice are used to describe the relationship
between the verb and the subject.
A sentence is in the active voice when the subject is the performer of the
action.
e.g. The woman reads the novel
     subject verb         direct object
A sentence is in the passive voice when the subject is the receiver of the
action.
e.g. The novel is read by all the students.
     subject     verb              agent
In this example the subject receives the action of the verb. The performer of
the action, if mentioned, is introduced by the word “by”. The performer is called
the agent.
Verbs in the passive voice can occur in all different tenses. The tense of the
auxiliary “to be” indicates the tense of the main verb.
e.g. The novel is read by the woman.
             present passive
    The novel was read by the woman.
               imperfect passive
     The novel has been read by the woman.
                perfect passive
     The novel had been read by the woman.
              pluperfect passive
     The novel will be read by the woman.
              future passive
     The novel will have been read by the woman.
              future perfect passive
In short, in English when an active sentence is changed into a passive one, the
following changes occur.
   1) The direct object of the active sentence becomes the subject of the
      passive sentence.
        Active: The mechanic is repairing the car.
                                              direct object
       Passive: The car is repaired by the mechanic.
                  subject
   2) The tense of the verb in the active sentence is reflected in the tense of
the verb “to
        be” in the passive sentence.
        Active:   We read the novel.
                     present
        Passive: The novel is (being) read.
                               present
       Active: We have read the novel.
                    perfect
       Passive: The novel has been read.
                          perfect
   3) The subject of the active sentence becomes the agent of the passive
      sentence.
Active: Many people saw the film.
             subject
Passive: The film was seen by many people.
                                    agent
