What is the grammar of a definite clause in junior high school?

The usage of the junior predicative clause is summarized as follows:

1. The concept of definite clauses: In compound sentences, the clauses that modify a certain noun or pronoun are called definite clauses. The modified noun or pronoun antecedent, the word that guides the definite clause is called a relational word, and the definite clause is generally placed after the antecedent.

2. Relative words of definite clauses: The relative words that guide definite clauses include relational pronouns and relational adverbs, common relational pronouns include that, which, who (accusative whom, possessive whose, etc., and relational adverbs include where, when, why, etc. Relative pronouns and relative adverbs are used to connect antecedents and definite clauses, and at the same time serve as important components of definite clauses.

3. Classification of definite clauses: According to the relationship between definite clauses and antecedents, definite clauses can be divided into restrictive definite clauses and non-restrictive definite clauses. The restrictive definite clause follows the antecedent immediately after the antecedent, the main clause and the clause are not separated by a comma, and the clause cannot be omitted.

There is a comma separation between the non-restrictive definite clause and the main clause, which plays a supplementary and explanatory role, and if it is omitted, the meaning is still complete.

4. Usage of relative pronouns:

1) That can be used to refer to both people and things. Be the subject, object, or predicate in a clause. It cannot be omitted as the subject, but it can be omitted as the object.

For example: Mary likes music that is quiet and gentleMary likes to be gentle**.

that as the subject).

2) Which is used to refer to something, as a subject, object or predicate in a sentence. The subject cannot be omitted, but the object can be omitted. For example:

the building which stands near the train station is a supermarket.The building near the train station is a supermarket. (as the subject).

1. The antecedents replaced by the words who, whom, and that are human nouns or pronouns, which are used as subjects and objects in the clauses.

For example: is he the man who wants to see you?Is he the person you want to meet? (who that is the subject in the clause).

2. Whose is used to refer to a person or thing, (only used as a definite term, if it refers to a thing, it can also be interchangeable with of which).

For example: please pass me the book whose (of which) cover is greenPlease hand me the green book.

3. The antecedent replaced by which, that is the noun or pronoun of the thing, can be used as the subject, object, etc. in the clause.

For example: a prosperity which that had never been seen before appears in the countrysideThere has been an unprecedented boom in the countryside.

which that is the object in the sentence).
