1、小升初语法第15讲：连词（二）知识点讲解与考题精练（有答案）连词（Conjunction）是用来连接词与词、词组与词组或句子与句子，表示某种逻辑关系的虚词。连词表示并列、转折、选择、因果等关系。如：“You and me.你和我。”“和”就是连词，表示并列。“You or me. 你或者我。”“或者”也是连词，表示选择。连词是一种虚词，不能独立担任句子成分，起前后连接作用，类似桥梁。连词主要分为并列连词和从属连词。【知识点】从属连词 从属连词是用来连接从句和主句的连词。从属连词后面连接的句子是从句，另一个句子是主句。常用的从属连词有when, before, after, as soon as
