除了主詞和受詞補語外，動詞、形容詞、副詞也可以有它們的補語。這些動詞、形容詞、副詞的補語並非修飾用的副詞或副詞片語，而是補充動詞、形容詞、副詞不足且必要的資訊。
但是在句型和文法分析的時候，我會把它們都視為是副詞，不論它們用來補足必要資訊，或額外的修飾。
In addition to subject complements and object complements, are there any other complements?

你說：
Can we consider verb complements and adjective complements adverbs or adverbial phrases?
ChatGPT 說：
Good question! While verb complements and adjective complements can sometimes resemble adverbs or adverbial phrases, they are not always the same. Let's clarify their roles.
1. Can Verb Complements Be Considered Adverbs?
Not exactly. Verb complements are essential to complete the meaning of a verb, while adverbs modify a verb but are not essential.
Key Differences:
Verb complements complete a verb’s meaning; removing them makes the sentence incomplete or ungrammatical.
Adverbs provide extra information about a verb, answering questions like how, when, where, or why, but they are not required for grammaticality.
Example of Verb Complements (Not Adverbs):
He wants to leave. (Infinitive phrase = verb complement; without it, "He wants" is incomplete.)
She enjoys reading books. (Gerund phrase = verb complement; without it, "She enjoys" is incomplete.)
Example of Adverbs (Not Verb Complements):
He left quickly. ("Quickly" modifies "left" but is not required for the sentence to be complete.)
She reads books often. ("Often" modifies "reads" but is optional.)
📌 Conclusion: Verb complements are necessary for a verb’s meaning, while adverbs are optional modifiers.
2. Can Adjective Complements Be Considered Adverbs?
Not really. Adjective complements complete an adjective’s meaning, while adverbs modify adjectives but do not complete them.
Key Differences:
Adjective complements provide necessary information to complete an adjective.
Adverbs modify adjectives but are optional.
Example of Adjective Complements (Not Adverbs):
He is afraid of the dark. (Prepositional phrase = adjective complement; "afraid" needs more information.)
She is happy to help. (Infinitive phrase = adjective complement; "happy" needs an explanation.)
Example of Adverbs Modifying Adjectives (Not Complements):
He is extremely afraid. ("Extremely" modifies "afraid" but is optional.)
She is very happy. ("Very" modifies "happy" but is optional.)
📌 Conclusion: Adjective complements are essential for completing the adjective’s meaning, while adverbs just modify adjectives.
Final Answer
Verb complements and adjective complements are NOT adverbs or adverbial phrases.
Adverbs modify verbs, adjectives, or other adverbs, but complements complete meaning.
The key distinction: Complements are necessary; adverbs are optional.
