Learning English grammar is a particular headache, that is, what clauses are there? I am in high school, attributive clauses and nominal clauses.

Hello. First of all, the components of a sentence are called sentence components. In a sentence, there is a certain combination relationship between words. According to different relationships, the sentence can be divided into different components. Sentence components are represented by words or phrases. English: A sentence consists of seven parts: subject, predicate, object, attribute, complement, adverbial and predicative.

Predicates are used to describe the identity, nature, character, characteristics and state of the subject. Predicates are usually served by nouns, adjectives, adverbs, prepositional phrases, infinitives, verbs -ing and clauses, and are usually located after verbs (be, become, apparent, seem, look, sound, feel, get, small, etc.). ). If the predicate of a sentence is also acted by a sentence, then the sentence that acts as a predicate is called a predicate clause (see/view/111752.htm # sub11752).

Attributive is used to modify, limit and explain the nature and characteristics of nouns or pronouns. Adjectives, nouns, pronouns, numerals, prepositional phrases, infinitives (phrases), participles, attributive clauses or words, phrases or sentences equivalent to adjectives can be used as attributes. In Chinese, "de" is often used. The relationship between attribute and head language is the relationship between modification and being modified, restriction and being restricted. In Chinese, between the head and the attribute, some need to use the structural auxiliary word "de", some don't, and some are optional. "De" is an attributive symbol (see/view146579.htm # sub146579).

Clauses in English are divided into nominal clauses, relative clauses (attributive clauses) and adverbial clauses.

1. Nominal clauses: All kinds of clauses that function as nouns in a sentence are called nominal clauses. According to their grammatical functions in sentences, such clauses can be called subject clauses, object clauses, predicative clauses and appositive clauses respectively.

Clause conjunctions: conjunctions: that, the, if, conjunctions do not act as any components in clauses, among which that has no meaning and cannot be omitted except as the leading word of the object clause; Whether or not and if there is a meaning of "whether".

Conjunctive pronouns: what, which, who/who/who are subject, object, predicative and attribute in clauses, in which WHO can only be subject, WHO can only be object and WHO can only be attribute.

Connective adverbs: when, where, why and how, which act as adverbials of time, place, reason and way in clauses.

Obviously, we need advanced management. Obviously, we need advanced management.

The question is who can compile this computer program. The question is who will compile this computer program.

They are faced with the question whether they should continue to work. They are faced with the question of whether to continue the work.

2. Relative clause is a clause structure guided by relative words. Its main function in compound sentences is to act as a noun modifier, that is, the role of attribute, so it is also called an attribute clause.

Attributive clauses are used as attributes in sentences to modify nouns or pronouns, and the modified nouns or pronouns are called antecedents. Attributive clauses usually appear after antecedents and are guided by related conjunctions (relative pronouns or adverbs).

2. 1 Functions and syntactic functions of relative pronouns

Functions are used for restrictive and non-restrictive attributive clauses, and for restrictive attributive clauses.

Action replaces people, substitution replaces people and things.

Subject, who, which and that.

2.2 The function of relative adverbs is syntactic function.

Relative adverbs are expressed in attributive clauses and act in attributive clauses.
