Directions:

     First, study the instructional material on subjects, verbs, and complements. Then the directions are always the same:
 

1.  Select any exercise. 

2. Place parentheses ( ) around every prepositional phrase. Draw a curved line from each opening paren to the word that the phrase modifies.

3. Underline finite verbs twice, their subjects once. Label complements (PA, PN, IO, DO).

You will find it much easier if you work your way through the text, one sentence at a time. Do your best with a sentence, then forget it and go on to the next.
