Examples: 


  "One car was parked outside of the gate." 
  "Your work volume is increased or not"
  "He was arrested"
  "She was raped"
  "After accident he was taken to hospital"
  "He was informed about this"
  “My heart was broken”


All above statements can be in the stative form if we do not mentioned the agent.
But if we use the agent i.e. By Driver, By Boss,  By Police, By  boyfriend, By  friend, By  father, By  husband respectively, then sentence become as passive voice.

My questions are 
a) How to quickly make out whether a sentence is in the passive voice or just a simple sentence (Stative)?

B) If i use had been in above sentence does it mean the same?


Question: Do metaphors tend to be an excuse for, or evidence of, imprecise thinking?
Answer: Making up new metaphors is evidence of thinking. Repeating other peoples' metaphors, and especially applying them broadly to things or events that don't fit the intent of the metaphor, rather than coming up with a more apt one, is evidence of a lack of creative thinking. What you notice most in the media are metaphors that have becom cliché. But hey, if the metaphor fits, wear it.  (I never metaphor I didn't like.)
