 ACTIVE AND PASSIVE VOICE

Active Voice (AV) :

       When the subject of the sentence is the doer of the action, then the sentence is in AV.

  Ex:     She writes a letter.

Passive Voice (PV) :

         When the subject of the sentence is the receiver of the action denoted by the verb, then the sentence is in PV.

  Ex:     A letter is written by her.

Changing AV to PV

• Subject -->Object and Object --> Subject
• Helping/ Auxiliary verb comes.
• Add ‘by’ before the new object. (Not required in some cases)

                Ex: He was elected the leader of the house. (Not required 'by')

• Change the verb to its ‘participle form’(V3)

• The PV is preferred when the doer is unknown or unimportant.

                   Ex:   The bridge was built in the 17th Century.

• When discussing history, the PV is often used.

                 Ex:    The war was fought with glory.

• The AV is used when the subject is more important than the object.
• Avoid using active and passive in the same sentence.

                 Ex:   The food was cooked and served.

                         Emma cooked and served the food.

• Use a single verb instead of two whenever is possible.

                     Ex:    Strucker enjoys good food and music.

                    ( Strucker enjoys good food and music is also enjoyed by him.)-->Awkward

PRESENT TENSE

PAST TENSE

  FUTURE TENSE

Note:

  Sentences with intransitive verbs cannot be changed to passive form because those verbs do not take objects after them.

  Ex:

    The sky is blue.

    He goes to school. (intransitive verb)
