Divide the following sentences into subject and predicate:
The man was old.
The weather turned cold.
The day grew stormy.
The boy became ill.
The concert proved successful.
What kind of man is referred to in the first sentence? What part of speech is "old"? What part of the sentence does it modify? In what part of the sentence does it stand? Could it be omitted? What then is its duty with reference to the verb? What are its two duties? (It completes the verb "was" and modifies the subject "man.")
Lead the pupils to deal similarly with "cold," "stormy," "ill," "successful."
Comparison, Abstraction, and Generalization, or Organization:
What two duties has each of these italicized words? Each is called a "Subjective Predicate Adjective." What is a Subjective Predicate Adjective? (A Subjective Predicate Adjective is an adjective that completes the verb and modifies the subject.)
