Noun clauses are commonly used conjunctions and detailed example sentences and explanations

Noun clause conjunction:

1. Conjunctions: that, whether, if do not act as any component of the clause).

2. Conjunctive pronouns: what, whatever, whoever, whoever, whom, whose, which

3. Conjunctive adverbs: when, where, how, why

Usage: (1) that: that connects the noun clause of the slow search, only plays the role of joining, and does not make components in the clause. It can be omitted in the object clause.

2) If and whether: have the meaning of whether or not, indicating general doubt. The subject clause and the predicative clause can only use whether, and whether cannot be used, and whether is not used as a component in the clause, but only plays the role of connecting the slag. Scramble the beam calendar.

3) Interrogative pronouns who, whom, whose, what, which: these conjunctions not only play a connecting role, but also make components of nouns or pronouns in the clause, such as subject, predicate, object, and definite. Conjunctive pronouns are missing, and the clause is incomplete.

4) Interrogative adverbs when, where, why, how: These conjunctions not only play a connecting role, but also make adverbial statements in the clause to indicate the time, place, reason and way.

The conjunctions of noun clauses are as follows:

1. Conjunctions: that, whether, if do not act as any component of the clause).

2. Conjunctive pronouns: what, whatever, whoever, whoever, whom, whose, which

3. Conjunctive adverbs: when, where, how, why

Usage: (1) that: that connects the noun clause, only plays the role of joining, and does not make the component redundant in the clause. It can be omitted in the object clause.

2) If and whether: have the meaning of whether or not, indicating general doubt. The subject clause and the predicative clause can only use whether, and cannot use and whether, nor do they make components in the clause, but only play a connecting role.

3) Interrogative pronouns who, whom, whose, what, which: these conjunctions not only play a connecting role, but also make components of nouns or pronouns in the clause, such as subject, predicate, object, and definite. Lack of concatenating bright prepronouns, incomplete clauses.

4) Interrogative adverbs when, where, why, how: These conjunctions not only play a connecting role, but also use Jing Changqing as an adverbial in the clause to indicate the time, place, reason and way.

Noun clauses include subject clauses, predicative clauses, object clauses, and copositional clauses. According to the common characteristics of these clauses, the conjunctions of noun clauses can be divided into three main categories: that, if whether and wh- (interrogative words).

Usage: 1 If a declarative sentence is used as the subject, predicate, object, or coposition of another sentence, then we generally use that as a conjunction. That itself has no meaning in a sentence and only serves as a connection.

2 If a general interrogative sentence is used as the subject, predicative, object, or homonym of another sentence, then we are going to use whether or if as a conjunction. whether if means 'whether' in a sentence. After becoming a noun clause, the word order of the original interrogative sentence should be changed to the word order of the declarative sentence (subject + predicate).

Subject: Predicate.

Note: The word order of the original interrogative sentence is changed to the word order of the declarative sentence in the clause, and the punctuation of the compound sentence is determined by the sentence structure of the main clause.

3 If a particular interrogative sentence is used as the subject, predicate, object, or coposition of another sentence, then we keep the original interrogative words as conjunctions, and the meaning of these interrogative words is also retained in the clause. After becoming a noun clause, the word order of the original interrogative sentence should be changed to the word order of the declarative sentence (subject + predicate).

Guiding noun clauses.

The conjunctions can be divided into three categories:

Conjunctions (5): that (meaningless in itself.) Lead a single object clause.

That can often be omitted, but leads to the subject clause.

Predicative clauses, homonymous clauses.

that is usually not omitted).

whether, if (both indicate "whether" indicates the uncertainty of the content of the clause).

as ifas though (both mean "as if", "seem").

None of the above acts as any component in the clause.

Conjunctive pronouns (10): what whatever, who whoever, whom whomever, whose whosever, which whichever

Conjunctive adverbs (7): when whenever, where wherever, how however, why

Non-omittable conjunctions:

1.Conjunctions after prepositions.

2.The conjunctions of the leading subject clause and the copositional clause cannot be omitted.

we heard the news that our team had won.

3.Make conjunctions of components in clauses. Both whether and if mean no. However, only whether:

1.whether leads the subject clause and begins the clause.

eg:whether he can come to the party on time depends on the traffic.

2.Guiding predicative clauses.

eg:the question is whether we can get in touch with her.

3.The whether clause is used as a prepositional object.

eg:i am thinking about whether i should quit my present job.

It can be used with or not, but only whether can be used immediately after or not.

we didn't know whether or not she was ready.(Only whether can be used at this time).

i wonder whether/if the news is true or not.(In this case, both can be used).

5.It is directly followed by the verb infinitive.
