专题06连词-初中英语重点语法知识完整梳理（全国通用）

连词【定义】连词是连接单词、短语或句子的一种虚词，起辅助作用，在句子中不单独作成分。根据在句子中所起的作用不同，连词通常分为并列连词和从属连词。并列连词用来连接属于同一层次并具有同等句法功能的词、短语或句子；而从属连词用来连接不同层次，带有主从关系的词、短语或句子。【知识归纳】一、并列连词并列连词词义例句and和，又，及Heislaughingandtalking.but但是，可是（表转折）Heispoor,buthonest.or或者（表选择）Wouldyouliketeaorcoffee?so因此，所以（表结果）Hewasill,sohecouldn'tgotoschoolyesterday.both...and...两者都Bothyouandsheareright.notonly...不但Notonlyyoubutalsoeveryoneherelikeswatchingbutalso...而且……footballmatch.either...or...或者或者EitherheorIamright.neither...nor...既不……也不……NeitherthetwinsnorLiLeihasbeentoShanghai.【特例清单】.“祈使句+or+结果句"="Ifyoudont其中or意为“否则”例：Hurryup,oryouwillbelate.快点,否则你就会迟到了！=Ifyouhurryup,youwon，tbelate.如果快点，你就不会迟到了。=Ifyoudoifthurryup,youwillbelate.如果不快点,你就会迟到了。but“但是”，用来表示转折关系，注意它不能与though,although连用so“所以,因此”用来表示因果关系,注意它不能与because,since,as连用for“因为”，表示原因，主要用来进行补充说明，没有因果关系notonly...butalso,neither…nor…和either...or...连接两个主语时，谓语动词与最近的主语保持一
