Understanding the Concept of Voice in English
In active voice, the subject performs the action. In passive voice, the subject receives the action, shifting emphasis to the recipient or outcome.
General Rules for Transforming Active to Passive
General transformation: The active object becomes the passive subject, appropriate form of ‘to be’ is added, main verb changes to past participle (V3), and agent is introduced with ‘by’.
Tense-by-Tense Auxiliary Verb Transformations
Present simple active (writes) becomes passive (is written); past continuous active (was reading) becomes passive (was being read).
Common Tricky Cases (Imperative Sentences and Modals)
Imperative commands like ‘Shut the door’ transform using ‘Let’: ‘Let the door be shut’.
