What is a noun clause in high school English? How many categories are there?

A clause that is the subject in a sentence is a subject clause.

The function of a noun clause is equivalent to a noun phrase, which can act as a subject, object, predicate, homonymous, etc. in a compound sentence. Therefore, according to its different syntactic functions in the sentence, the noun clause is divided into subject clause, object clause, predicative clause and copositional clause.

A conjunctions that lead to noun clauses.

The conjunctions that guide noun clauses can be divided into three categories:

Dependent conjunction: (does not act as a clause.) any ingredient).

Conjunctive pronouns: what, whatever, who, whoever, whoever, whom, whomever, who, which, whichever

Conjunctive adverbs: etc.

Non-omitted conjunctions: 1Conjunctions after prepositions 2Conjunctions that lead to subject clauses and homonymatic clauses.

The difficulty of noun clauses.

1. The word order (word order) of the noun clause

2. The difference between noun clauses leading words.

1. The difference between whether and i f.

both whether and if mean yes. But whether cannot be replaced by an IF if:

whether leads predicative clauses and copositional clauses.

In the subject clause, if it is used as the formal subject, if whether is acceptable; Otherwise, just use whether

we will attend the meeting hasnt been decided

it hasnt been decided whether / if we will attend the meeting.

When leading an object clause after a preposition.

In English, according to the different grammatical functions of clauses, they can be divided into six categories: subject clauses, predicative clauses, object clauses, copositional clauses, definite clauses and adverbial clauses.

The first four types are commonly called noun clauses because the functions of subject clauses, predicative clauses, object clauses and homotopic clauses in the sentence are equivalent to nouns; The function of a definite clause is equivalent to an adjective and is called an adjective clause; Whereas, the adverbial clause function is equivalent to an adverb and is called an adverbial clause.

Where leads to a place adverbial clause where leads to a place adverbial clause such as where there is a will, there is a way--Where there's a will there's a way. The biggest feature is that the place adverbial clause part belongs to the subordinate position, which can be omitted and only the main clause there is a road is left.

The predicative clause needs to have antecedents This sentence has no antecedents In its entirety, the sentence is place, the adverbial clause where there was violence, and the main clause drugs were always behind it, the subject-subordinate compound clause is the object of saw.

A1: In the adverbial clause where there was violence, the connecting word where is not the subject or object in the clause but only the adverbial, and the remaining there was violence is the main system table also called the active complement structure. Where and there are no mutual constraints, i.e. only one of them can be used.

Sentence encoding is carried out entirely according to syntactic needs.

A2: The linking word in this sentence is where the one before there was violence, which is very simple A connecting word connects two complete sentences, there was violence and drugs were always behind itare two complete sentences where neither the subject-verb-object is missing, and where acts as a conjunction, leading the place to the adverbial clause.

First of all, see the structure of this sentence, the transitive verb saw omitted the that guide the object clause, the clause ( where ) there was violence , drugs were always behind it , and superimposed the where leading adverbial clause, the whole sentence is the object clause in the adverbial clause, there should not be understood as a place adverbial, there is there there structure table exists.

Examples of the same where: where there is a will, there is a way--Where there's a will there's a way.

Not as a leading pronoun for the later there, so it can't be explained by your statement.

2.There are no conjunctive words in this sentence.

The whole sentence translates as: As a police officer, I saw that there was violence behind drugs. This means that drugs can easily lead to violence.

For example, a sentence: where there is a will, there is a wayWhere there is something, there is a way. I don't know if you understand?

where there is a will there is a way.Where there's a will, there's a way, you must know this sentence. I'll change this sentence to look like the one above, you see:

as a student, i know where there is a will , a way is there.

A1, although there is a place adverbial, but it is used in the there be sentence structure, we often say, there are some kids playing on the playgroundThen I ask you, we all have it here, why do we have to be on the playground

Feel for yourself the peculiarity of the sentence structure).

A2, I'll change your sentence again:

as a policeman,i saw that drug were always behind it where there was violence.

where leads the definite clause modifying the pronoun it

Actually, it still feels a little weird... You should ask your English teacher, o(o).

i saw [(where there was violence ,)drugs were always behind it .]

The inside is the object clause, and the inside () is the adverbial clause in the object clause.

there does not affect where, there is the predicate, where is the adverbial, and it cannot be involved.

( where ) there was violence is an object clause that omits that, because there was violence is not lacking in components, a conjunctive adverb is required. Note the punctuation comma, which must be followed by a complete sentence.
