see how we form the Passive Voice.
we have this active sentence: They
are building the castle.
passive equivalent will be: The
castle is being built
has happened between the “active” sentence and the “passive”
have changed the subject of the sentence and we have brought in the verb
to be plus the past participle of the active verb.
this is the way we form the passive voice.
let’s see some examples with different tenses:
present, active: They keep the jewels in the safe
present, passive: The jewels are kept in the safe
continuous, active: Soldiers are repairing the drawbridge
continuous, passive: The drawbridge is being repaired by the soldiers
past, active: Some invaders attacked the castle
past, passive: The castle was attacked by some invaders
continuous, active: The constable was carrying the legal documents
for the meeting.
continuous, passive: The legal documents were being carried by the
active: A lady will visit the castle next weekend
passive: The castle will be visited next weekend by a lady
continuous, active: John the Fool will be training the bear for the
continuous, passive: The bear will be trained by John the Fool for
the royal show
active: The servants would prepare the banquet in the main dining
passive: The banquet would be prepared by the servants in the main
Perfect, active: They have signed an important decree
perfect, passive: An important decree has been signed by them
see when we use the Passive voice:
the subject is unimportant or irrelevant and we want to stress the thing
done instead of the doer of the action, such as:
The castle was built in 1226
we move from the active into the passive, the preposition “by”is
placed in front of the person carrying out the action: The throne was
built by the master carpenter.
