I was given a book on my birthday by him.

Extra Information ↴

(1) The object in the active voice becomes the subject in the passive voice.

(2) The subject in the active voice becomes the object in the passive voice. It is generally preceded by the preposition 'by'.

(3) The main verb (the finite verb) of the sentence is changed into its past participle form, and it is preceded by the correct form of 'be' verb in passive voice.

(4) The passive voice of the verb with two objects is formed by changing either of the two objects (preferably the Personal Object) into the subject and retaining the other as the 'retained object'.

(5) When the subject is a 'noun', it is used unchanged in passive voice but if the subject is a 'pronoun', the correct objective form of that pronoun should be used in passive voice.
