Agent In a passive clause, we usually use a phrase beginning with by if we want to mention theagent - the person or thing that does the action, or that causes what happens. Examples: My mother   makes   sandwich every morning. Subject     verb1+s/es      O            C (adv. of time) Sandwich is made  by my mother every morning. Subject     to be+V3      Agent               C (adv. of time)
present continuous : [ S + to be + being +V3 (past participle) present perfect: [ S + has/have + been + V3 (past participle)
present continuous			Active Passive		A young boy is catching a butterfly. A butterfly is being caught by a young boy.
present perfect			Active Passive		Yano has returned the book to the library. The book has been returned to the library by Yano.
If you want to change an active sentence which has two objects into its passive forms, there are two ways: 1. Make its indirect object into the subject of the passive sentence. 2. Make its direct object into the subject of the passive sentence.
Examples: Active:			John  is giving  his girl-friend a bunch of flower. indirect object      direct object
Passive: The indirect object as the subject			John’s girl-friend     is being given         a bunch of flower.
Passive: The direct object as the subject			A bunch of flower    is being given to John’s girl-friend.
