Changing the Active verb into the Passive

When a sentence in the active voice is changed to the passive voice, the following changes occur:

1. The object of the active verb becomes the subject of the passive verb.
Alice invited John. (Active voice: subject – Alice; active verb – helped; object - John)
John was invited by Alice. (Passive Voice: subject – John; passive verb – was invited; object - Alice)
2. The verb changes its form according to the number and person of the subject.
have written a novel. (Subject – I; verb – have written)
A novel has been written by me. (Subject – a novel; verb – has been written)
3. The subject of the verb in the active voice becomes the object of the verb in the passive voice and is introduced with a preposition like by.
They built this house in 1990.
This house was built by them in 1990.
4. The active verb changes its form to become the passive voice.
am writing a letter. (Active verb – am writing)
A letter is being written by me. (Passive verb – is being written)

When the active verb has two objects

If the active verb has two objects, either of them can become the subject of the passive verb.
Ann will give you a present. (Active Voice)
You will be given a present by Ann. (Passive voice - indirect object becomes subject.)
A present will be given to you by Ann. (Passive voice - direct object becomes subject.)

Passive verb forms

Changing imperative sentences into the passive

The imperative sentence in the passive voice takes the following form:
Let + object + be + past participle

When the active voice is in the negative, the passive voice takes the following form:
Let not + object + be + past participle

Help me. (Active Voice)
Let me be helped. (Passive Voice)
Do it at once. (Active Voice)
Let it be done at once. (Passive Voice)
Carry it home. (Active Voice)
Let it be carried home. (Passive Voice)
Do not beat the dog. (Active Voice)
Let the dog not be beaten. OR Let not the dog be beaten. (Passive Voice) 
Sometimes we want to begin the sentence with you so that the emphasis is on the person addressed. In such cases, the passive voice takes the following form:
Help me. (Active Voice)
Let me be helped. (Passive Voice)
You are requested to help me. (Passive Voice)
Don’t touch it. (Active Voice)
Let it not be touched. (Passive Voice)
You are warned not to touch it. (Passive Voice) 
The passive form has to begin with you, when the object of the verb in the active voice is not given.
Work hard. (No object) (Active Voice)
You are requested to work hard. (Passive Voice)
Get out. (No object) (Active Voice)
You are ordered to get out. (Passive Voice)
