How to distinguish between a preposition and a conjunction, the difference between a preposition and

Prepositions and conjunctions 1 and, with, with, with.

Sometimes it's a conjunction, sometimes it's a preposition, and it's hard to distinguish between them. Such as:

The younger brother and the younger sister left. (conjunction).

My brother borrowed books from my sister. (preposition).

There are three ways to distinguish it:

1) The components before and after the conjunctions are equal, and the positions can be swapped without the semantics basically unchanged. The preposition's preposition has a primary and a secondary, and cannot be interchanged, otherwise the meaning will all change. Such as:

The younger brother and the younger sister left. =

My sister left with my brother.

My brother borrowed books from my sister. ≠

My sister borrowed books from my brother.

2) If the predicate is preceded by an insertion"Both"、"Full"、"Together"and other words"And, with, with, with"It must be a conjunction. Such as:

The younger brother and the younger sister left. =

My sister and brother are gone.

My brother borrowed books from my sister. ≠

My sister and brother both borrowed books.

3) If"And, with, with, with"Some adverbial adverbs (eg"All the time"、"Always"), it must be a preposition. Such as:

The younger brother and the younger sister left. A * brother has been with his sister all the time.

My brother borrowed books from my sister. A younger brother has been borrowing books from his sister. 2 Because, because, for.

It is both a preposition and is used in a single sentence; Again, a conjunction, which is used in a compound sentence. The distinction is as follows: if it is followed by a body of speech word, it is a preposition. If it is followed by a predicate word, it is a conjunction. Such as:

He spent three years abroad because of his work. (preposition).

Because of the correct coaching, everyone made rapid progress. (conjunction).

Because of this incident, Xiao Wang was praised. (preposition).

Because Xiao Wang saved people, he was praised. (conjunction).

1. The composition before and after is differentConjunctions: Conjunctions are equal in composition and can be swapped without changing the semantics.

Preposition: The components before and after the preposition have a primary and secondary, and cannot be interchanged, otherwise the meaning will all change.

2. Different classificationsConjunctions: Conjunctions are divided into two types: parallel conjunctions and subordinate conjunctions.

Prepositions: Prepositions can be divided into temporal prepositions, place prepositions, mode prepositions, cause prepositions, quantitative prepositions, and other prepositions.

3. Different usageConjunctions: Parallel conjunctions: Parallel conjunctions: Parallel conjunctions: juxtaposed words, phrases, clauses, or sentences; Subordinate conjunctions are used to lead clauses.

Preposition: A preposition cannot be used on its own, it must be used with an object to form a prepositional phrase or to be used after a verb in a thing. Prepositional phrases play the role of adverbial, definite, predicative, and object complement in a sentence.

Prepositions and conjunctions 1 and, with, with, and sometimes conjunctions, sometimes prepositions, belong to conjunctive words, and it is difficult to distinguish them. For example, my brother and sister are gone.

Conjunction) The younger brother borrows a book from his sister. There are three ways to distinguish between (prepositions): (1) The components before and after the conjunctions are equal, and the positions can be swapped without the semantics basically unchanged.

The preposition's preposition has a primary and a secondary, and cannot be interchanged, otherwise the meaning will all change. For example, my brother and sister are gone.

My sister left with my brother. My brother borrowed books from my sister. My sister borrowed books from my brother.

2) If the predicate is preceded by an insertion"Both"、"Full"、"Together"and other words"And, with, with, with"It must be a conjunction. For example, my brother and sister are gone.

My sister and brother are gone. My brother borrowed books from my sister. My sister and brother both borrowed books.

3) If"And, with, with, with"Some adverbial adverbs (eg"All the time"、"Always"), it must be a preposition. For example, my brother and sister are gone.

A * brother has been with his sister all the time. My brother borrowed books from my sister. A younger brother has been borrowing books from his sister.

2 Because, because of, for are both prepositions and are used in a single sentence; Again, a conjunction, which is used in a compound sentence. The distinction is as follows: if it is followed by a body of speech word, it is a preposition.

If it is followed by a predicate word, it is a conjunction. For example, he spent three years abroad due to his work.

Preposition) Because the coach is right, everyone makes rapid progress. (conjunction) Because of this incident, Xiao Wang was praised. (preposition) Because Xiao Wang saved people, he was praised.

(conjunction).

In most cases, conjunctions and prepositions are very different, and the key is to grasp the grammatical characteristics of the two: the conjunction plays a connecting role, and the parts of speech before and after it are connected must be the same, such as "run and jump" and "you or me"; A preposition is an introductory function, and in the sentence component, before the verb predicate, it acts as an adverbial and after it as a complement.

Let's take "and" as an example to talk about how to distinguish between prepositions and conjunctions.

When "and" is used as a preposition, the components before and after "and" cannot be interchanged, and an adverb can be added as an adverbial in front of it, and there can be a pause in the back.

When "and" is used as a conjunction, the components before and after "and" can be interchanged, and the adverbial modifier cannot be added in the front, and there can be no pause in the back.

Do you know how to distinguish between imitation conjunctions and prepositions?

1.Conjunction:

Conjunctions are used to connect sentences, phrases, or words and express the relationship between them. Common conjunctions are:"and"(and),"but"(But),"or"(or) etc. They play the role of connecting different components in a sentence and can connect subjects, verbs, nouns, adjectives, adverbs, clauses, etc.

For example:"i like coffee and tea."(I love coffee and tea.) - Concatenate two parallel nouns.

he is tired, but he keeps working."(He's tired, but he keeps working.) - Concatenate two sentences side by side.

2.Preposition:

Prepositions are used to denote concepts such as location, direction, time, manner, cause, etc., and to associate nouns, pronouns, or verb phrases with other sentence components. Common prepositions are:"in"(in),"on"(on top),"at"(in),place)."for"(for) etc.

They usually appear before noun phrases and are used to illustrate the relationship between nouns. For example:

i live in a house."(I live in a house.) (preposition)."in"Represents a positional relationship.

she went to the store."(She went to the store.) (preposition)."to"Indicates the direction.

It is important to note that there are some words that can be used as both conjunctions and prepositions, and the specific use depends on the context. For example:"after"(in),After that) can be used as a conjunction to connect two sentences, or as a preposition to indicate a temporal relationship.

The four words "and", "with", "with", and "with" can be used as both conjunctions and prepositions, so how can we distinguish them? To sum up, it can be roughly analyzed from the following three aspects:

1) If the two words connected by the conjunction "and" are combined, they can generally be reversed and the basic meaning of the sentence remains unchanged. The two noun words before and after the preposition "and" have no direct grammatical relationship and cannot be used in interchangeable positions.

For example, "Dream of Red Mansions" and "Water Margin" are both classical masterpieces. (The positions can be swapped without the basic meaning of the sentence being the same).

I talked to him about it. (Positions cannot be swapped).

2) The preposition "and" can be preceded by the current language, and the conjunction "and" cannot be preceded by the current situation.

I talked to him about it. - I talked to him about it a few days ago.

3) The conjunctions "and" can be omitted, and the prepositions "and" cannot be omitted or replaced with a ton.

"Red Mansions Sell Dreams" and "Water Margin" are all classical masterpieces.

In order to accurately express ideas and avoid ambiguity, in the Constitution of our country, "and" is used as a conjunction, and "same" or "with" is used as a preposition. For example:

My country has established and developed diplomatic relations with other countries on the basis of the principles of equality, mutual benefit and mutual respect for sovereignty and territorial integrity.

It can be seen that if they are used together, it is generally customary to use "and" as a conjunction and "same" as a preposition. For example:

Xiao Wang quarreled with Xiao Zhang and Xiao Li. Brother Zheng Xiaoli and Xiao Zhang quarreled with Xiao Wang.

Conjunctions are used to connect two sentences, separated by a comma, and generally have two predicate verbs. Prepositions have no meaning, and they have to be matched with nouns and objects to have a certain meaning.

(conjunction).

A conjunction is a virtual word that cannot serve as a sentence component on its own, but only as a connecting word to word, phrase to phrase, and sentence to sentence.

Conjunctions can be divided into 4 main categories: coordinating conjunctions. Inflective conjunctions. Choose conjunctions and causal conjunctions.

Conjunctions can also be divided into 2 categories: coordinating conjunctions and subordinate conjunctions.

(preposition).

Prepositions, also known as prepositions, indicate the relationship between nouns, pronouns, etc., and other words in the sentence, and cannot be used as a separate sentence component in the sentence. A preposition is generally followed by a noun, pronoun or other parts of speech, phrase or clause equivalent to a noun as its object, indicating the relationship with other components.

A preposition and its object form a prepositional phrase, which is used as an adverbial, predicate, complement, definite or prepositional object in a sentence. At the same time, the usage of prepositions is also very flexible, the same preposition can express multiple meanings, and prepositions can be divided into time prepositions, place prepositions, mode prepositions, reason prepositions, quantitative prepositions, and other prepositions.

Preposition: indicates the relationship between nouns, pronouns, etc. and other words in the sentence, and cannot be used as a separate sentence component in the sentence. A preposition is generally followed by a noun, pronoun or other parts of speech, phrase or clause equivalent to a noun as its object, indicating the relationship with other components.

Conjunction: It is a kind of imaginary word, which cannot be used as a sentence component independently, but only plays the role of connecting words and words, phrases and phrases, and sentences and sentences.
