高三英语一轮复习语法专题---定语从句的判断及基本用法课件(共31张PPT)

定语从句的判断 及基本用法 定语从句 Sentence pattern 英语句式可分为三类：简单句(Simple sentence)，并列句(Compound sentence)和复合句(Complex sentence) What’s the definition of these three patterns? 当一个句子只包含一个主谓结构时称为简单句。 含有两个或两个以上独立分句的句子叫并列句，这些独立分句处于平等的、互不依从的并列地位。 复合句是一个主句和一个或一个以上的从句构成。主句是全句的主体，通常可以独立存在；从句则是一个句子成分，不能独立存在。但是从句也有主语和谓语部分。所不同在于，从句须由一个关联词引导，起到联系从句和主句的作用。 Which sentence pattern is it? She was an author and she wrote this great book. She was an author. She wrote this great book. She was the author who wrote this great book. 并列句 简单句 复合句 How to distinguish an attributive clause?
