To convert a sentence from passive to active voice, you must identify the subject, the verb, and the object and rearrange them so that the subject performs the action.
Identify the components of the passive sentence:
Object (receiving action): "A letter"
Verb (passive form): "is written" (Present Tense)
Subject (performing action): "The citizen" (indicated by "by")
Time Indicator: "every week"
Steps for Conversion:
Move the performer to the front: The performer "The citizen" becomes the new subject of the sentence.
Change the verb form: The passive "is written" (Present Tense) changes to the active form "writes." We use "writes" because the subject ("The citizen") is singular.
Place the receiver after the verb: The original subject "A letter" becomes the object.
Retain the prepositional phrase: "to the editor" and the time indicator "every week" remain in their logical positions.
