You have already learnt that, when you change active voice to passive voice:

– Change the position of the object and the subject. (This turns the object into the subject, but it doesn’t do the action.)
– Add ‘be’ (in the correct tense) and the past participle.
– If you want to say who or what did the action, add “by” the thing or person who did it.
– Change the subject pronoun to the object pronoun.

We sometimes use the verb ‘get’ with a past participle to form the passive voice. Examples:

– Don’t use that cup because you might break it. ► Don’t use that cup because it might get broken.
– My father got injured at work.

Note: If there are pronouns in the sentences you are changing, then they need to change too.

me ►I; him ► he; her ► she; us ► we; them ► they. (‘You’ and ‘it’ stay the same.)

Examples: Active voice ► Passive voice

Someone gave me a book. ► I was given a book.
Someone gave him a book. ► He was given a book.
Someone gave her a book. ► She was given a book.
Someone gave us a book. ► We are given a book.
Someone gave them a book. ► They were given a book.

Examples of passive voice in past, present and future tenses: 

The shop/shops has/have been closed now. (present perfect tense)
The shop/shops had been closed for several weeks. (past perfect tense)
The shop/shops will have been closed by then. (future perfect tense)

Examples of passive voice with modals:

The shop/shops could be closed today.
The shop/shops might be closed today.
The shop/shops has/have to be closed today.
The shop/shops must be closed today.
The shop/shops should/ought to be closed today.
