Please talk about the grammar of Chinese and English in senior high school. "What are Chinese, prepositions and words?" And "What are English, Predicate and Complement?"

1. Auxiliary words are function words attached before or after words, phrases and sentences, which indicate structural relations or some additional meaning. There are three kinds of auxiliary words: structural auxiliary words, tense auxiliary words and mood auxiliary words. Structural auxiliary words such as "de", "de" and "de", tense verbs such as "le" and "zhe", and mood auxiliary words such as "ma", "ne" and "ba".

2. Prepositions are words used to express the relationship between words and sentences. You can't be a sentence component alone in a sentence. Prepositions are usually followed by a noun pronoun or other parts of speech, phrases or clauses equivalent to nouns as objects. A preposition and its object form a prepositional phrase, which is used as an adverbial, predicative, complement or prepositional object in a sentence.

Such as: middle, middle, middle, middle and so on.

3. Conjunction is a kind of function words, which can't be a sentence component independently, but only plays the role of connecting words with words, phrases with phrases, sentences with sentences. Conjunctions can be divided into two categories: coordinate conjunctions and subordinate conjunctions.

Such as: and, and, but, although, but and so on.

English

Preposition:

Prepositions, also known as prepositions, are function words and do not constitute any sentence elements in a sentence alone. A preposition must be followed by a noun, a noun phrase or a noun clause to form a prepositional phrase, which can serve as various sentence components in a sentence, such as: The flowers in our garden are in full bloom. In this sentence, the prepositional phrase in our garden is place, which is used as an attribute to modify flowers, and the prepositional phrase in full bloom is used as a predication to indicate the state or situation of the subject. I met Mary before lunch. I met Mary before lunch. This prepositional phrase acts as an adverbial of time in the sentence before lunch.

Preposition is one of the most active parts of speech in English. The same preposition and different words can express different meanings. Many idioms are composed of prepositions and other words. Therefore, mastering prepositions is the key to learning English well. Prepositions have three forms, they are:

1. Simple prepositions, such as:

On, after, during, and starting from.

Some simple prepositions are transformed from the present participle adding, for example:

Consider, care, care and so on.

2. Synthetic prepositions, such as:

Into, up, inside, outside, nothing, through and so on.

3. A compound preposition consists of two or more words, such as:

According to, because, in front, in front, because and so on.

Note: No matter how many words a compound preposition consists of, the last word must be a preposition.

Adverbs:

Adverbs are words used to modify verbs, adjectives, adverbs, prepositions, conjunctions and other words or phrases to illustrate the characteristics of the nature or state of behavior. The main syntactic function of adverbs is to act as adverbials and modify verbs, adjectives, adverbs, prepositions, conjunctions or certain phrases, even the whole sentence. Adverbs can make the description of language more specific, comprehensive and vivid, so they play a powerful role in transmitting information and exchanging thoughts and feelings.

Commonly used adverbs are: now, before, before, today, tomorrow, always, oft, sometimes, already, late, soon, here, there, easy, comfortable, Hardy, happy, sad and so on.
