英语语法：连词

高中英语语法总结大全之连词●要点清单连词连词是一种虚词，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。

连词主要可分为两类：并列连词和从属连词。

并列连词用来连接平行的词、词组和分句。

如：and,but,or,nor,so,therefore,yet,however, for,hence,as well as,both…and,not only…but also,either…or,neither…nor,(and)then等等。

并列连词与并列结构并列连词引导两个并列的句子。

1)and与or判断改错：(错)They sat down and talk about something. (错)They started to dance and sang.(错)I saw two men sitting behind and whisper there.(对)They sat down and talked about something. (对)They started to dance and sing.(对)I saw two men sitting behind and whispering there.解析：第一句：and连接两个并列的谓语，所以talk 应改为talked。

第二句：and连接两个并列的动词不定式，第二个不定式往往省略to，因此sang应改为sing。

第三句：and连接感观动词saw后面的用作的宾补的两个并列分词结构，因此whisper应改为whispering。

注意：and还可以和祈使句或名词词组连用表示条件。

（or也有此用法）Make up your mind,and you'll get the chance.=If you make up your mind,you'll get the chance. One more effort,and you'll succeed.=If you make one more effort,you'll succeed.2)both…and两者都She plays(both)the piano and the guitar.3)not only…but(also),as well as不但…而且）She plays not only the piano,but(also)the guitar.注意：not only…but also关联两个分句时，一个分句因有否定词not而必须倒装。
