How to Change Active Voice into passive Voice?
1. Make the object of the active sentence—Subject of the passive sentence.Example : I write a letter. (Active Voice)
Object of active sentence is ‘a letter’. It becomes subject of the passive sentence. (A letter..)
2. Make the subject of the active sentence---Agent of the passive sentence. The agent will be in objective form. Use ‘by’ before it. ‘By’ is used when the subject of active sentence is important to mention.
Subject of active sentence is ‘I’ Its objective form is ‘me’. So …..by me.
3. Always use third form of the verh (Past participle) in passive structures.
The past participle (V-III) will be preceded by ‘to be’ form of verb, as per the tense of the sentence.
4. Please take care that the ‘to be’ form of verb is governed by the new subject (subject of the passive sentence).
Examples - a. I write a letter. (Active)
A letter is written by me. (Passive)
b. She is helping the students. (Active)
The students are being helped by her(Passive)
Here in sentence (b), plural verb ____are is used as per the new subject __students.
5. Change of the subject of the active sentence into the object of the passive is done as per the following table.
