*The same meaning obtains for a sentence in the active and the passive but the question lies in the FOCUS the speaker has between the subject or the object. He may desire to highlight the SUBJECT or the OBJECT in his/her utterance.
* *The voice rendition only obtains with sentences containing the transitive verbs- verbs that take an object.
*** In the Active sentence, the subject determines the concord of conjugation. Mary scores the point =Subject+Verb+Complement.
****In the passive sentence, the object becomes the subject and the subject becomes the agent introduced by the preposition ‘BY’. The point is scored by Mary. NB: The agent is optional in a sentence. The point is scored.
***** The passive verb is BE+PAST PARTICIPLE. ‘BE‘ takes the tense of the main verb in the active sentence, followed by the past participle of the main verb.
