Active and Passive Voice/ Change of Voice

Active and Passive Voice/ Change of Voice
( Source: S. Chauhan Institute of English: 98135-81301)
Dear students, the sentences we write or speak are generally in active or in passive voice.
Question: Can we change all active sentences in passive voice?
Ans. No, we cannot change all the active sentences in passive voice. This is because some active sentences do not need objects.
It means the sentences which need objects can be changed into passive construction.
What are transitive and intransitive verbs?
If the verb in a sentence needs an object, it is called transitive verb. But the verb that does not need any object is called intransitive verb.
So it is necessary to find out an object in an active sentence.
How to find out an object in an active sentence?
(i)                         Pick out the main verb from the sentence.
(ii)                      Put question ‘what’ or ‘whom’ to it.
(iii)                   Answer will be supplied by the object.
(iv)                   If there is only one object in the sentence, it is called direct object.
(v)                      If there are two objects, the one that gives the answer to ‘whom’ is indirect one.

See the following examples:
(i)   I composed an e-mail to my friend yesterday.
Main verb= composed
Question: Composed what?
Answer: e-mail. It is a direct object.
(ii)                      I composed an e-mail to her yesterday.
Question: to whom?
Answer: my friend
So ‘my friend’  is indirect object.
Rules to change active voice in passive voice:
Active sentence:
Subject + verb + object

I          composed   an e-mail   to my friend yesterday.
Passive sentence:
Object             + Verb+           by+      subject
 
An e-mail     was composed        by         me         to my friend yesterday
