Question

1. copular verbs do not express ______________
2. instead, they connect the subject to _________________________

Explanation:

For question 4: Copular verbs (like be, seem, become) don't express action. They are linking verbs, so the blank is typically "action". For question 5: Copular verbs connect the subject to a subject complement (like a predicate noun, adjective, etc.), so the blank is "a subject complement (or a predicate adjective/noun)".

Answer:

1. action
2. a subject complement (or a predicate adjective/noun)
