This document provides examples for converting sentences from active to passive voice in three types: 1) Subject + verb + object sentences are converted by making the object the subject. 2) Subject + verb + object + indirect object sentences are converted by making either the object or indirect object the subject. 3) Sentences containing reporting verbs such as "say", "think", "know" are converted using "it is/was said/thought/known" or "subject is/was said/thought/known to verb". The document provides over 30 examples across these three types to illustrate converting sentences to the passive voice.
