Question

They have painted the doors (change into passive voice)

Answer 1

the doors have been painted by them

Answer 2

The given sentence in passive voice is: The doors have been painted by them.

• To write a sentence from active voice to its passive form various rules are to be considered which include:

1. Identification of the tense of the sentence in active voice, which is past perfect tense in this question.
2. The rule is: "have" turns to "have been".
3. The subject "They" becomes the object and is written at last by changing its form to "them".
4. The object "the doors" which is the object becomes the subject and remains as it is.
5. The verb "painted" is not changed while only "have been" is written before it.

• Hence, the answer is provided.
