I am very confused about the types of Chinese phrases in senior one. There seems to be a mistake. What is this 2 1 brother phrase?

Children, brothers, let's popularize the knowledge of phrase types for you first!

Say what a phrase is first. Phrases are linguistic units that can be collocated and combined at syntactic, semantic and pragmatic levels, and are also called phrases. It is a grammatical unit, bigger than a word, but not a sentence. Simple phrases can be used as syntactic components of complex phrases, and phrases with sentence tone can be sentences.

There are five basic phrase structures, namely, subject-predicate structure, verb-object structure, radical structure, coordinate structure and complement structure.

Subject-predicate phrases can be composed of nouns or pronouns plus verbs or adjectives, which is the most basic type of phrase structure. There is also a kind of subject-predicate phrase that is special, and the predicate part is served by nouns. Verb-object phrases consist of verbs and nouns. There are two types of phrases: neutral phrases and formal phrases. An attributive phrase consists of an attributive and a head, which can be a noun or pronoun. A phrase in adverbial form consists of an adverbial and a head word, and the head word is a verb or an adjective. There are also two kinds of complement phrases, namely, verb-complement phrases and form-complement phrases, and the structural auxiliary word "de" is the symbol of complement. There is no difference between the words of coordinate phrases, they are equal and joint. Coordinate phrases often need the same part of speech, but there are some differences.

Now let's do the problem!
