Question

there are a lot of things to do voice change​

Answer 1

A lot of things are there to be done

Answer 2

Active Voice refers to a sentence in which the subject is performing an action.

Passive Voice refers to a sentence in which the subject undergoes the action. In other words, it is writing the sentence in reverse order.

Example: She is taking down notes. (Active)

                Notes are being taken down by her. (Passive)

NOTE: Sentences that convey habitual actions/have intransitive verbs cannot be changed in to passive mode.

There are a lot of things to do. (Active)

A lot of things are there to be done. (Passive)
