Question

all the milk has been drunk by the cat change into active voice​

Answer 1

The cat has drank all the milk.

To change to active voice, we swap the position of the subject and the object of the sentence.

Here, the subject in the sentence is cat which occurs towards the end and the object is milk which occurs towards the beginning. After swapping, cat will occur towards the beginning and milk will occur towards the end.

We can also see that the tense is in simple past tense. While changing the sentence to active voice, we have to maintain the form of the tense. In this case, you change been drunk to drank.

Answer 2

Answer:

The cat Drank all the milk
