This question is very big, not a few sentences, I suggest you take a look at Mr. Wei's "Complete Breakthrough in Grammar for the High School Entrance Examination" ** tutorial, which contains all the grammar points to be mastered in junior high school. You can find it by searching the Internet.

Junior English grammar includes: simple present tense, present continuous tense, simple future tense, simple past tense, object clause, definite clause, adverbial clause, etc.

1. Simple present tense: Regular, anti-** action or behavior and a certain current situation.

2. Present continuous tense: indicates the actions and behaviors that are being carried out at the present stage or when speaking.

3. Simple future tense: Indicates an action that is about to take place, or a state of existence and an intention, a plan or a preparation to do something.

4. Simple past tense: an action or state that occurred at a certain time in the past; Habitual, regular actions and behaviors in the past.

5. Object clause: The clause that plays the role of an object in a sentence is called an object clause.

6. Determinative clause: A clause that modifies nouns and pronouns in a compound sentence is called a definite clause.

7. Adverbial clause: The adverbial clause represented by the clause in a compound sentence is called an adverbial clause, which can be used to modify a predicate (including non-predicate verbs), a definite or an adverbial, or the whole sentence.

Junior high school grammar includes subject clauses, definite clauses, predicative clauses, object clauses, etc. Grammar is simply the rules of language. English grammar is the rules of use of the English language, which studies the structure and use of the English language.

English grammar consists of two parts: lexical and syntactic.

Lexical is the analysis and description of the classification of words, the collocation relationship between words, and their variations in application. The syntax mainly analyzes and analyzes the various types of sentences, various sentence components, and the rules of word choice and sentence formation.

The role of grammar

Make learning easier: Since grammar is the study of the rules and rules of language use, when we master certain grammatical knowledge through grammar learning, we can make full use of the grammar rules we have learned to analyze language phenomena, summarize language characteristics, and discover language rules, so as to make English learning simpler and easier.

Make the expression more accurate: Having certain grammatical knowledge can make us use language more accurately, for example, we can analyze some unfamiliar linguistic phenomena through grammar. In addition, for some difficult long sentences, we can also use grammatical analysis to help understand.
