1. Definition

The above four sentences are all subject-subordinate complex sentences containing attributive clauses. The attributive clause is used as a _______ clause in a compound sentence to modify the _______ words or pronouns in the main clause.

2. Usage

In an attributive clause, the modified word is called the antecedent. The attributive clause is usually located in the antecedent ________ (before/after) and is introduced by the relative word. In junior high school, we need to be able to identify and understand attributive clauses guided by relative pronouns such as that, which, and who. Which refers to ________, who refers to ________, and that can refer to both ________ and ________. That or which is used as a ________ slang or a ________ slang in a clause; when used as a ________ slang, that or which can be omitted.

3. Note:

That and which are interchangeable when referring to things, but that must be used in the following situations.

(1) When the antecedent is all, everything, nothing, little something, anything, etc.

That is all that I know. That's all I know.

(2) When the antecedent is preceded by ________ modification.

He was the first person that helped me. He was the first person that helped me.
