they had not done their work change the sentence from active to passive voice
Answers
Answer:
In such a sentence one is " Dummy Do", the meaningless one the support of which we seek in Simple Present and Simple past where there is no auxiliary or modal but the sentence is to be made negative or interrogative.
Ignore this first DO, the meaningless one, we call do support.
They ( did) NOT DO the work.
We know 'do support' embodies the tense and person of the finite verb. Thus deduced, the sentence is in simple past.
Let's make it passive.
The work was not done by them.
We know BE Verb in a sentence is conspicuous by its presence in the sense that it precedes the subject in questions and turns negative all by itself without support of any helping verb, irrespective of the fact that BE VERB is there either as a main verb or as an auxiliary.
