Passive Voice
   It tells what is done to someone or something. 
   The object is the doer of the action. 
   The form of a passive sentence is: Subject + to be + past participle of the verb 

A little reminder: 

1. In passive sentences above, the subjects are the italicized words. When making an active voice a passive voice, the one being talked about will be the subject.  
2. Passive voice is used for a formal tone and if you want to focus on what is “done” or the “action” rather than who did it. 
3. Active voice is used to convey direct meaning.
