连词ProducedbyZhangYaling连词ProducedbyZhangYaling概念连词是一种虚词,它不能独立地担任句子成分,只是连接词与词、短语与短语以及句子与句子的作用。英语中连词只要分两类：并列与从属连词。

并列连词：用来连接平行的词、短语或分句。 从属连词：用来引导一个从句。概念连词是一种虚词,它不能独立地担任句子成分,只是连接词与词连词是用来连接词、词组和句子的虚词。分为并列连词和从属连词。并列连词连接两个分句，构成并列句。

用从属连词引起两个分句，构成复合句。

连词是用来连接词、词组和句子的虚词。分为并列连词和从属连词。并列连词：

a.并列关系：and，aswellas,either…or notonly…butalso，both…and neither…nor.

b.转折关系：but，yet，or.

c.因果关系：for，so.
