The first sentence came out of nowhere, from the deepest part of his soul, two coordinate adverbials, which show the predicate verb and his mother object.

The second sentence is ellipsis. The complete sentence should be: Why does he draw his mother now?

The third sentence, interrogative sentence, his mother subject, as a predicate verb, what object, as an adverbial of place in his sentence, as an adverbial of time, like this prepositional phrase as an attribute, modifies time.

The fourth sentence, It subject, is a connecting verb and a simple predication.

In the fifth sentence, the subject is always adverbial of degree, auxiliary verb is used, predicate verb tell, indirect object him, and the whole sentence is used as direct object tell. When you feel nervous, anxious or afraid, you can call it an object clause, and take a deep breath.

In this clause, when you feel nervous, anxious or once afraid, it is an adverbial clause of time. You are the subject of the clause and feel it is a copula. Tense, anxiety or even fear are three juxtaposed adjectives as predications, and even adverbs modify fear. Or a conjunction.

The subject "you" of the main sentence is omitted, and the verb, object, attribute and breath are modified.
