Passive
- Use
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.
Form
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" (or is left out)
- object of the "active" sentence becomes subject in the "passive" sentence
- subject of the "active" sentence becomes "object" in the "passive" sentence" (or is left out)
