Final answer:
The sentences 'What do they do?', 'Did you enjoy your class?', and 'Somebody is watching us.' have been converted into passive voice as 'What is done by them?', 'Was the class enjoyed by you?', and 'We are being watched by somebody.' respectively. The utilization of passive voice ensures the doer of the action can be omitted or de-emphasized if necessary.
Step-by-step explanation:
Changing sentences into the passive voice involves making the subject of the active sentence the object in the passive sentence and introducing a form of the verb 'to be' with the past participle of the main verb. If the doer of the action is unknown or irrelevant, it is either omitted or introduced by the preposition 'by.' Here are the sentences provided, transformed into passive voice:
- What is done by them?
- Was the class enjoyed by you?
- We are being watched by somebody.
In these examples, 'done', 'enjoyed', and 'being watched' indicate the past participle forms of the verbs 'do,' 'enjoy,' and 'watch,' respectively. The phrases 'by them,' 'by you,' and 'by somebody' illustrate the optional presence of the doer in passive constructions.
It is critical to recognize when passive reading occurs to ensure engagement with the text for effective comprehension and learning. Similarly, in writing, the passive voice might be used strategically to shift focus or maintain objectivity.
