Question

Rule of passive and active

Answer 1

The subject and the predicate interchange their places in the sentence

Answer 2

There are two basic rules for converting sentences from Active Voice into Passive Voice, which are common for all tenses.

The places of subject and object will be interchanged in the sentence. Only 3rd form of the verb or Past Participle (e.g. written) will be used as a main verb in Passive Voice.

Eg.Active voice:I write a letter.

Passive voice:A letter is written by me.
