Active and Passive Voice are two forms of any transitive verb. In passive sentences, we always use the past participle form of a verb. However, the syntax changes with each tense. Similarly, the passive form of the transitive verb DO is DONE and it’s used with different auxiliary verbs in different tenses. The following examples show the use of DO in its passive form in different tenses. They may help you understand its usage better:

a)     Simple Present:

Syntax: Object + am/is/are + DONE

Example: Sweeping is done every morning by them.

b)     Present Continuous:
