The passive voice restructures a sentence such that the object of an action becomes the subject, and the subject (the doer of the action) is introduced with a preposition, typically "by." Let's take the active sentence: "I was busy cleaning the house," and transform it into the passive voice.
Step 1: Identify the subject, verb, and object.
The subject is "I," the verb phrase is "was busy cleaning," and the object is "the house."
Step 2: Move the object to the subject position in the passive sentence.
The new subject becomes "The house."
Step 3: Use the appropriate form of the verb "to be" followed by the past participle of the main verb.
The verb "cleaning" in its continuous form changes to "was being cleaned" to match the past continuous tense.
Step 4: Introduce the original subject with "by."
The original subject "I" becomes "by me."
Construct the passive sentence:
The house was being cleaned by me.
