Final answer:
The active sentence 'Bobo threw the ball to dad' in passive voice is 'The ball was thrown to dad by Bobo.' The transformation involves making the ball the subject of the sentence and using the past participle 'was thrown' with 'by Bobo' indicating the actor.
Step-by-step explanation:
To convert the active sentence 'Bobo threw the ball to dad' into passive voice, we need to make the object ('the ball') the subject of the sentence. When we do this, the sentence changes to 'The ball was thrown to dad by Bobo.' Here, 'was thrown' is the past participle of 'throw' coupled with a form of the verb 'to be,' and 'by Bobo' indicates who performed the action.
In the active voice, 'Bobo' is the subject performing the action of throwing, and in the passive voice, the emphasis shifts to the object, 'the ball,' which is being acted upon. Passive voice is often used when the focus is on the action itself or when the actor is less important. However, in narrative writing, active voice is typically preferred for its clarity and directness.
