You should be attentive.
When the adjective comes before a noun, it's called an attributive adjective, and when the adjective comes after the verb To Be (i.e., be, is, am, are, were, was, etc), it's called a predicate adjective.
You should be attentive. (Predicative: BE + adjective)
She is an attentive student. (Attributive: Adjective + Noun)
The difference between attributive and predicative adjectives is distance, or proximity. Attributive adjectives are next to, or close to the nouns they modify, whereas predicate adjectives are far away from the nouns they modify:
You should be attentive. (Predicative: far away)
She is an attentive student. (Attributive: next to, close)
