2. It is said that a prayer is in PASSIVE VOICE when the significance of the verb is got by the grammatical person to whom that one refers:


Buenos Aires was founded by Pedro of Mendoza.


(Buenos Aires was founded by Pedro of Mendoza).


3. He is formed with the auxiliary one of the verb to be and the participle spent from the verb that conjugates.
4. The complement of the active prayer goes on to subject of the passive one. Since in Castilian, the subject of the active one can remain as fastened agent.




5. When a verb has two complements two structures can be done of passive:


a) To book was sent to Tom by Mr. Smith, A book was sent to Tom by Mr. Smith.


b) Tom was sent to book by Mr. Smith (passive idiomatic). This structure is not possible in Castilian.
