PASSIVE Voice, a sentence emphasizes the action or the object of the sentence.The given sentence is in the active voice and 'The jury' is the subject and 'the case' is the object.When we convert this sentence into passive voice, the subject 'The jury' of the active voice becomes the object, the object 'the case' becomes the subject.The passive FORMAT "am/is/are + being + third form of the VERB (V3)" is used.This is the active and passive voice rule for the PRESENT continuous tense.Hence, "The case is being considered seriously by the jury" is the correct passive voice. Verbs of passive format have a different set of tenses (*V3 - Past participle or Third form of the Verb) as given below in the table: TENSEACTIVEPASSIVEPASSIVE CONVERSIONPresent SimpleHe plays footballam/is/are + V3Football is played by himPresent ContinuousHe is PLAYING footballam/is/are + being +V3Football is being played by himPresent PerfectHe has played footballHas/have + been+ V3Football has been played by himPresent Perfect ContinuousHe has been playing footballNot used and unusual.Not used and unusualPast SimpleHe played footballWas/were + V3Football was played by himPast ContinuousHe was playing footballWas/were + being + V3Football was being played by himPast PerfectHe had played footballHad + been + V3Football had been played by himPast Perfect ContinuousHe had been playing footballNot used and unusualNot used and unusualFuture SimpleHe will play footballWill + be + V3Football will be played by himFuture ContinuousHe will be playing footballNot used and unusualNot used and unusualFuture PerfectHe will have played footballWill have been + V3Football will have been played by himFuture Perfect ContinuousHe will have been playing footballNot used and unusualNot used and unusual The sentences of the following tenses cannot be converted into Passive voice:Present Perfect Continuous (or Progressive) Tense.Past Perfect Continuous (or Progressive) Tense.Future Continuous (or Progressive) Tense.Future Perfect Continuous (or Progressive) Tense.
