Question

Nobody has been seen in the library .how to change into passive voice

Answer 1

The given sentence is already in the passive voice and can only be changed into the active voice:

We have not seen anyone in the library.

• In case of active voice, the subject directly performs an action.

So, the structure is: Subject+ verb+ object

• In case of passive voice, the subject interchanges its position with the object.

So the structure is: Object+ verb+ subject

• In the given sentence, there is no direct subject so we have used 'We' as the subject in the active voice.
