We form the standard passive with be + -ed form. We form the get passive with
get + -ed form:
The trees in the garden were damaged in the wind. (standard passive)

passive, we also place a little more emphasis on the nature of the action
itself or on the person involved in the action:
There were blizzards over night and the whole town got snowed in. (‘Get
snowed in’ here means to be unable to leave the town because of heavy falls
of snow.)
I’ve got good news for you. Jim finally got promoted.

The get passive is commonly used in speaking of events that are negative or
not desired:
They’ve worked there for three years but they still got sacked (lost their
jobs).
He feels his paintings are always getting criticised.
Our car got stolen last night.
We sometimes use a reflexive pronoun with the get passive. This suggests the
subject was at least partly responsible for the event or made it happen:
I got myself locked out the other day. I stupidly left my keys in the
bedroom. (or I got locked out …)
