Active Voiceను PASSIVE Voiceలోకి ఎలా మార్చాలి?

The PASSIVE
Passive voice is used when the focus is on the action (things done). (అంటే చేసే వ్యక్తి కంటే చేసిన పని ముఖ్యం అరుునప్పుడు ఉపయోగిస్తాం. Many times it is not important or not known, who is performing the action. అవసరం కూడా లేదు.
Eg: » My car was stolen. /Milk is sold here
       » Computer courses are taught in this institute.
       » Hyderabad was named after its founder in 1816.
In the examples above, the focus is on the facts. Sometimes a statement in Passive is more polite than Active Voice, as the following example shows:
Eg:   » A mistake was made.
[ఫలానా వాళ్లు చేసారు అనే దాని కంటే]

Form of Passive
Example: A letter was written.
When rewriting Active sentences in Passive Voice, Follow the following steps:

• The object of the active sentence becomes the subject of the passive sentence.
• The form of the verb is changed.
• మారిన కొత్త object ముందర by పెట్టాలి .

Eg: My grandmother planted this tree.
          sub                      verb    obj
This tree was planted by my grandmother.
Active Voice నుంచి Passive Voice లోకి మార్చినప్పుడు Verb కింది విధంగా మారుతుంది:

Active: They sell milk here.
Passive: Milk is sold here.
(Who sells milk is not important. That's why no agent is required.)
Active: You must close these doors.
Passive: These doors must be closed.

Passive Voice is chiefly used
When the doer of an action is not important.
(E.g. Streets are swept every day.)

In the absence of information or insufficient information.
(Eg. The car was serviced.)

When the agent is 'someone' 'people' etc. we omit the agent and also 'by' before it.

IT concessions are not given to salaried employees.
When we have to tone down a statement or disclaim it. ఒక విషయం చెప్పడానికి మొహమాటం పడేటప్పుడు .

This seal is already broken.
(in stead of saying: Have you opened it?)

Now-a-days expressions in Passive Voice are not encouraged. Active expressions take fewer words.

(eg. It has been raining since morning.)

[కాషాయ] clothes for 5 years.)
