What does the main family table mean in English grammar?

The main family table is a basic structure, which is subject+copula+predicative. The subject is the object of sentence description, the predicate describes the nature, status and attributes of the subject, and the copula acts as a conjunction connecting the subject and the predicate.

Typical cardinality table structure: I+am+xxx, which means "I am ……", where I is the subject, xxx is the predicative describing the nature of I, and the be verb am is the link. The predicative xxx can be both a noun and an adjective. I am a student. I am a student. I am tired. I'm very tired.

Linking verb

In addition to the most basic be verbs, copula verbs also include sensory copula verbs. Such as feeling, smell, sound, etc. Example: This dish smells delicious. This sentence is also an explicit structure. The dish is the subject and the verb is a verb, which means "smell". Diligence is an adjective that describes the nature of this dish.
