C Uses
We use the passive:
ь to avoid mentioning the doer
The accounts have now been prepared.
We are not interested in who prepared the accounts; so an active sentence cannot be used.
ь to emphasise the doer with a 'by' phrase
The figures have been prepared by our new accountants.
In speech, we usually put the information to be emphasised at the end of a clause. We call this 'end- weight'. So here 'our new accountants' gets more focus than 'the figures'.
ь in process descriptions
At the final stage, the finished products are packed into boxes.
We are not interested in the agent, but in the action.
ь in impersonal language
Hard hats must be worn on the building site at all times.
The passive is widely used in formal written announcements, where an impersonal tone is intended.
