Final answer:
To convert 'Our classes were being taken by the senior most teachers' to active voice, rephrase it to 'The senior most teachers were taking our classes', making the subject the doer of the action.
Step-by-step explanation:
Changing sentences from passive to active voice involves making the subject of the sentence the doer of the action, resulting in stronger and clearer statements. The sentence 'Our classes were being taken by the senior most teachers' can be converted to active voice by rephrasing it to 'The senior most teachers were taking our classes'. By doing so, the sentence no longer has the subject receiving the action, but instead, the subject is conducting the action.
In active voice, the sentence becomes more direct and engaging, as it attributes the action of teaching directly to the subject, which is 'the senior most teachers' in this case. It's essential to identify the form of the verb 'to be' and the past participle in the passive sentence and replace them with the appropriate active verb form. This switch from passive to active voice also eliminates the need for the preposition 'by', which is commonly used in passive constructions to introduce the doer of the action.
