Formation of Imperatives in Passive Voice
Commands, suggestions, and requests are imperative sentences.
In imperative sentences (command), the active voice is changed into passive voice by using
let + object + be + past participle form of the main verb. For example:

Carry the bag home. (active)
O
Let the bag be carried home. (passive)
O
In imperative sentences (suggestion), the active voice is changed into passive voice by using
subject + must/should + be + past participle form of the main verb. For example:
Take meals at regular intervals. (active)
O
Meals should be taken at regular intervals. (passive)
O
In imperative sentences (request), the active voice is changed into passive voice by replacing
please with you are requested. For example:
Please lend me your book. (active)
O
You are requested to lend me your book. (passive)
O
Verbs that cannot be used in Passives

The sentences having intransitive verbs cannot be converted into passive voice. The only Active and Passive Voice
reason for this is that such a sentence has no object. When a sentence has no object, it cannot
be changed into passive voice. Generally, they are followed by adjectives, adverbs, verb
complements or prepositions. For example:

Five children died of malaria. The car arrived late, so we got late.
O O
Some common intransitive verbs that are not followed by objects are:

arrive cough act come
rise die cry excel
swim go laugh respond

emigrate immigrate sit run
smile lie
