高中英语语法填空考点篇一:高考英语语法填空连词考点及练习高考英语语法填空连词考点及练习一、知识点考点解密在近两年广东高考的语法填空中连词,都是两小题,占语法填空的五分之一,是考查的一个重要项目,具体考点有以下4大点:考点1:并列连词注:(1)when作并列连词,主要用于was/were doing sth. when sth./sb. did; was/were about to do sth. when sth./sb. did; was/were on the point of doing sth. when sth./sb. did等句型中,表示“当某人或某物正在或正要做某事,就在这时突然又发生了另一事”。
(2)在“祈使句+and/or+陈述句”句型中,祈使句表示条件,and/or后的句子表示结果。
考点2:引导状语从句的连词考点3:引导名词性从句的连接词名词性从句有主语从句、表语从句、宾语从句和同位语从句。
引导这些从句的连词有:(1)连词that:只起连接作用,没有任何意思,不作任何句子成分,在宾语从句中可省略。
(2)连词whether:有“是否”之意,但不作句子成分;引导宾语从句时,还可用if。
(3)连接代词:who(m), whose, which, what等均有各自的意义,在从句中作主语、宾语、定语等。
其中what除有“什么”“多么”外,还有“所……的”之意,相当于thething(s) that…。
(4)连接副词:when, where, why, how等,有意义,在从句中作状语。
(5)whoever, whatever, whichever等也可引导名词性从句,意为“无论/不管……”。
考点4:引导定语从句的关系词定语从句就是在复合句里充当定语的从句,它通常紧靠在所修饰的名词或代词后面。
引导定语从句的关系代词和关系副词及使用场合如下表:注: (1)先行词是occasion常用when,先行词是case, situation, scenes等时常用where。
高中英语连词经典习题(含答案)一、单项选择连词1._____________ comes will be welcome to the open-air concert.A.Whatever B.WhoeverC.No matter what D.No matter who【答案】B【解析】句意:无论谁来参加露天音乐会都会受到欢迎。
可知主语是人。
no matter who只能引导让步状语从句,不能位于句首,而Whoever则没有此类限制。
故只能选B。
2.He was about to tell me the secret __ _____ someone patted him on the shoulder.A.as B.until C.while D.when【答案】D【解析】试题分析:句意:她正要告诉我这个秘密,这时有人拍了一下她的肩膀。
beabouttodo...when...是固定句型,意为“正要做……这时……”。
考点:考查连词。
【名师点睛】用when引导时间状语从句的句型结构搭配beabouttodosthwhen刚要,即将;正要做某事,突然发生其他事bedoingsthwhen正在做某事突然haddonesthwhen刚刚做过某事突然beatthepointofdoingsthwhen就在做某事的关键时刻突然scarcely...when/hardly...when几乎未来得及就…;刚一……就……nosooner...than一……就……3.I’m sorry I got caught in the traffic;_________, I could have been here sooner.A.besides B.althoughC.anyway D.otherwise【答案】D【解析】考查含蓄虚拟条件句。
I could have been here sooner是和过去事实相反的虚拟语气,四个选项中只有otherwise可以充当含蓄虚拟条件,相当于if I had not got caught in the traffic.所以选D。
