1. Put parentheses ( ) around each prepositional phrase.
2. Underline subjects once, finite verbs twice, and label complements (PN, PA, IO, DO).
3. Place brackets around each subordinate clause. If the clause functions as a noun, label its function (PN, IO, DO, OP) above the opening bracket. If it functions as an adjective or adverb, draw an arrow from the opening bracket to the word that the clause modifies. Put a vertical line at the end of every main clause.
4. Put a box around every gerund and gerundive. If it is a gerund (i.e., it functions as a noun) indicate its function over the box. If it is a gerundive, draw an arrow to the word it modifies. Put an oval around every infinitive and indicate (as in three above) its function.
5. Use the following labels for the additional constructions:
NuA -- Noun used as an AdverbAn Ass, having put on the Lion's skin, roamed about in the forest
and amused himself by frightening all the foolish animals he met in
his wanderings. At last coming upon a Fox, he tried to frighten him
also, but the Fox no sooner heard the sound of his voice than he
exclaimed, "I might possibly have been frightened myself, if I had not
heard your bray."
