Question

a new bike was not bought by my father into active voice​

Answer 1

Answer:

My father did not buy a new bike.

Explanation:

✮ When the subject is performing the verb in the sentence, the sentence is in the active voice.

     » She was not eating her lunch.

✮ When the subject is receiving the verb in the sentence, the sentence is in the passive voice.

     » Her lunch was not being eaten by her.

To change the given sentence from passive voice to active voice,

• The subject and the object have to be identified and swapped. In the sentence, the subject is 'my father' and the object is 'a new bike'.
• The word 'by', indicating towards the subject, has to be removed.
• We can identify the tense of the sentence by the auxiliary. The tense of the sentence is Past Simple.
• Now is the tricky part! The auxiliary has to be removed and the participle has to be changed to the tense of the sentence. Since the verb is negative ('not buy'), an auxiliary has to be added as well. Thus, 'was not bought' → 'did not buy'.
