2021年中考英语专题复习讲义----第八讲 连词 （基础版）（含答案）

第八讲：连词
专题概述：
连词连接词与词、词组与词组或句子的桥梁。它是英语单词、词组和句子的逻辑符号，属于并列关系的词、词组、句子由并列连词连接，而从属连词用采连接两个有主从关系的句子。
语法考点：
1. 并列连词：并列连词用来连接平行的词、短语或句子；并列连词按照其在句中的作用可分为表示并列关系、转折关系、选择关系和因果关系的连词。
2. 从属连词：从属连词是用来引导从句的词。
连词(Conjunction)
是一种虚词，它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。连词主要可分为4类:并列连词.转折连词.选择连词和因果连词。连词也可以分为2类:并列连词和从属连词。
表示并列关系的并列连词
and (和；又；而且), as well as( 也 ； 和 )；both...and...( 既……又……)；not only...but also...( 不仅……而且……)；neither...nor... (既不……也不……)。
连词
