The Passive is formed by BE + ED (past participle)
In a passive sentence the object of an active verb
becomes the subject of the passive sentence
Active : - Columbus discovered America
Passive : - America was discovered by Columbus
N.B Only transitive verbs (that is, verbs that take an object) are used in the passive.
+ The passive is used when it is more convenient or important to stress the thing done than who performed it, or when the person who did the action is not known
Active: - The thief stole my wallet.
Passive : - My wallet was stolen (more usual)
