Залог — это форма глагола, которая показывает, является ли подлежащее предложения производителем или объектом действия, выраженного сказуемым. Как уже было сказано выше, в английском языке имеется два залога: The Active Voice И The Passive Voice.
We only use the passive when we are interested in the object or when we do not know who caused the action.
Example: Appointments are required in such cases.
We can only form a passive sentence from an active sentence when there is an object in the active sentence.
To be + past participle
How to form a passive sentence when an active sentence is given:
— object of the «active» sentence becomes subject in the «passive» sentence
— subject of the «active» sentence becomes «object» in the «passive» sentence»
