Students often like the passive voice because it is logical. If we were to introduce a pattern for the structure of Passive Voice we would have to identify 2 of them, depending on the form:
Regardless of which pattern we need to use one thing is common for all passive voice structures:
we change the word order plus we change the form of a verb (into verb III).
subject-> verb → object to object → verb → subject
As we learnt before, in an active sentence (a standard sentence) the subject does the action to the object: Subject → Action → Object
I drive the car.
In a passive sentence, we change the sentence order putting the object at the beginning of the sentence – Object → Action → Subject
The car is driven by me.
Let’s back it up with examples showing active and passive for each tense / structure:I drive the car.

We use Passive Voice in order to:
eg My car has been stolen. (We don’t know who did it.)
It is said that she is very talented. (It’s not important who says it.)
eg It’s requested that you do not smoke in here.
My cake has been eaten.
