How to distinguish between main clause and clause can distinguish the six major clauses in English

1. The six relations between the main clause and the subordinate clause: causal relationship, example relationship, contrast relationship, concession relationship, hypothetical relationship, and definition relationship.

2. In English, a sentence that can be stored independently is called a cong elimination as a main sentence, and a sentence that is only used as a component of the sentence and cannot exist independently is called a subordinate clause. The clause is guided by a related word and a subordinate conjunction, and the structure of the clause is a related word subordinate conjunction + subject + predicate + other components. The main clause is the subject + predicate + other components, so, whether the clause is in front or after, the connecting word is always with the clause.

The main sentence is the main body of the sentence, and the sentence that can be used or appear alone is a sentence that contains constituent sentences. A clause is relative to a main clause, that is, it is subordinate to a certain main clause and cannot be a separate sentence. Clauses are divided into noun clauses (subject clauses, object clauses, predicative clauses, copositional clauses), definite clauses, and adverbial clauses.

1.Emphasis on the structure of declarative sentences

it is was + the emphasized part (usually the subject, object, or adverbial) + that who (when the subject is emphasized and the subject refers to the person) + the other part.

Example: it was yesterday that he met li ping

2.Emphasis on the structure of a general interrogative sentence

Same as above, just put is was in front of it.

The example was it yesterday that he met li ping?

3.Emphasis on the structure of special interrogative sentences

The emphasized part (usually an interrogative pronoun or interrogative adverb) + is was + it + that who + other parts?

Example: when and where was it that you were born?

Sentence pattern of emphasis

a.The sentence pattern is: it is not until+emphasis+that+other.

Ordinary sentence: he didn't go to bed until/till his wife came back.

emphasis: it was not until his wife came back that he went to bed

b.Note: This sentence pattern only uses until, not till.

But if the sentence structure is not emphasized, till and until can be used universally; Because in the sentence pattern it is was not....It's already a negative sentence, and the subordinate clause after that should use an affirmative sentence, and don't use a negative sentence anymore.

5.Emphasis on predicate verbs

is/was...that...The structure cannot emphasize the predicate, if the predicate needs to be emphasized, use the auxiliary verb do do or did

do sit down.Please be seated.

do be careful when you cross the street.When crossing the street, be careful!

b.Note: This emphasis only uses do does and did, and there is no other form; The past tense is used did, and the predicate verb that follows it is in the original form.

A sentence that can exist independently is called a main clause, while a sentence that is only used as a component of the sentence and cannot exist independently is called a clause. The clause is guided by a related word and a subordinate conjunction, and the structure of the clause is a related word or a subordinate conjunction plus the subject plus the predicate plus other components; A main clause is the main body of a sentence, which can be used alone or appear in a sentence, and is a sentence that contains constituent sentences, and the structure is the subject plus the predicate plus other components.

Classification of clauses

1.Subject clause: A clause used as a wide and missing subject is called a subject of the main wandering clause. The related words that guide the subject clause are subordinate conjunctions, interrogative pronouns, interrogative adverbs, condensed conjunctive pronouns, condensed conjunctive adverbs, etc.

2.Predicative clause: A clause used as a predicative clause is called a predicative clause. The related words of the leading predicative clause are many the same as those of the introductory subject clause.

3.Object clause: A clause that acts as an object in a sentence is called an object clause. There are three categories of object clauses: object clauses of verbs, object clauses of prepositions, and object clauses of adjectives.

4.Homonymous clause: It is one of the main clauses in the noun clause (subject clause, predicative clause, object clause, copositional clause), and the subordinate clause is used as an isoposition to express the actual content of the noun (phrase) with the same position, and its role is equivalent to a noun, and the previous noun (phrase) is supplemented or further explained, which is equivalent to a predicative clause, and the relationship between them is the isotopic relationship, that is, the main table relationship.

5.Determinative clause: It is a clause guided by a relative pronoun or a relative adverb, and its function is to make a definite clause to modify a certain noun component of the main clause, which is equivalent to an adjective, so it is also called an adjective clause, which is generally followed by the antecedent word it modifies.

6.Adverbial clauses can be divided into: time adverbial clauses, place adverbial clauses, cause adverbial clauses, conditional adverbial clauses, purpose adverbial clauses, concession adverbial clauses, comparative adverbial clauses, mode adverbial clauses, and result adverbial clauses.
