初中英语语法连词
连词考查要求：通过连词来考查对句子的整体理解是近几年中考的热点，如两个分句的逻辑关系、结合连词考查的状语从句、连词的具体意义等。
经常考查的重点连词有and，but，or，while，however及引导从句的连词if和whether；before和after等。
考点一：并列连词并列连词用于连接语法地位相同的单词，短语以及句子的连词。
一．并列连词主要分四类：1.表平行或承接关系的并列连词，并列连词连接的双方是对等的。
( and, both… and…, neither… nor…, not only … but also…, as well as …等)2.表转折关系的并列连词( but, yet, while, however等)3.表选择关系的并列连词( or, either… or…, not…but…)4.表因果关系的并列连词( for, so等)二．并列连词的几个注意点1. 主谓一致(1) both… and…连接主语时，谓语动词用复数形式；Both Lucy and Lily speak Chinese well.(2)either… or…, neither… nor…, not only … but also…连接主语时，遵循“就近原则”；(或者..或者) （既不...也不）（不但...而且）Either Tom or his friends have been to China.(3)as well as …连接主语时，谓语动词与前面的主语在人称和数上保持一致。
（看前不看后）I as well as they am ready to help you.2. 不能同时出现在一个句子中的连词So 与because, but与although/though不同同时出现在句子中，只能二选一。
3. and 与or区别(1) and 用与肯定句，or 用与否定或疑问句(2) 否定句中，连接的两部分都有否定时，应用and.Jim has no sisters and no brothers.(3) 否定句中，without 后面的并列用and连接；肯定句中，without 后面的并列用or 连接Man can’t live without water and air. = Man will die without water or air.考点二：从属连词用来引导从句的连词。
初中英语语法归纳：连词
初中英语语法归纳：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。
第一类表示并列关系的连词并列连词：并列连词用来连接平行的词、词组和分句。
1)and 和判断改错：(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：1. 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 succeed2, A and B 当表示整体或者指同一人时谓语动词用单数, 当and连接的单数名词前分别有each，every，many等词修饰时，谓语也用单数。
