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:

Syntax: Object + am/is/are +being + DONE

Example: Research is being done to find a cure for cancer.

c)     Present Perfect:

Syntax: Object + has/have + been + DONE

Example: The work has already been done.

d)     Simple Past:

Syntax: Object + was/were + DONE

Example: All his marriage shopping was done in just two days!

e)     Past Continuous:

Syntax: Object + was/were + being + DONE

Example: No work was being done yesterday.

f)      Past Perfect:

Syntax: Object + had+ been + DONE

Example: The housework had already been done by Mr. Smith, when the guests arrived.

g)     Simple Future:

Syntax: Object + will + be + DONE

Example: No work will be done tomorrow.   

h)    Future Perfect:

Syntax: Object + will + have + been + DONE

Example: The homework will have been done by sunset.

i)      Modals (Can/Could/May/Might/Must/Should/Used to):

Syntax: Object + Modal + be + DONE

Example: More and more research must be done to discover an affordable way to convert sea water to drinking water.
