The Opening of "The Tell-Tale Heart"
-- Edgar Allan Poe

1. Place parentheses ( ) around each prepositional phrase. 
2. Underline verbs twice, their subjects once, and label complements (“PA,” “PN,” “IO,” or “DO”). 
3. Place brackets [ ] around each subordinate clause. If the clause functions as a noun, label its function. If it functions as an adjective or adverb, draw an arrow from the opening bracket to the word that the clause modifies.
4. Place a vertical line after each main clause. 

     TRUE! — nervous — very, very dreadfully nervous I had been and 

am; but why will you say that I am mad? The disease had sharpened 

my senses — not destroyed — not dulled them. Above all was the 

sense of hearing acute. I heard all things in the heaven and in the 

earth. I heard many things in hell. How, then, am I mad? Hearken! 

and observe how healthily — how calmly I can tell you the whole story.
