状语从句
思维导图
易考易错点总结
状语从句包括时间状语从句、地点状语从句、条件状语从句、让步状语从句、原因状语从句、目的状语从句和结果状语从句。
对状语从句的考查主要集中在连接词上,尤其要重视as,until,before,since,when,incase等连词的各种语义功能和语法功能。
具体来说主要包括:
1.考查状语从句的连接词。
要掌握各个连词的含义及其用法,还有它们之间的区别。
如:
时间状语的连词有while,when,as,assoonas,until,not…until,before,after,since等;条件状语从句的连词有if,unless,incase,onconditionthat,provided(that),supposing,suppose(that)等;结果状语从句的连词有so…that(如此……以至于),such…that(如此……以至于)等。
2.考查固定搭配和习惯用法的连接词。
如:
nosooner…than…,hardly…when…,scarcely…before…,themoment/minute,directly。
3.考查不同性质的连词在不同的语境中所表达的不同意义。
如:
as既能引导时间状语从句,又能引导原因状语从句和让步状语从句;where能引导地点状语从句和定语从句等。
4.考查状语从句的时态。
主要考查在时间、条件、让步状语从句中用一般现在时表将来及用一般过去时代替过去将来时的用法。
5.考查状语从句的省略。
在时间、原因、条件、方式、让步等状语从句中,常常省略相同的主语或作主语的代词it以及be动词,保留现在分词、过去分词、介词短语、不定式等成分。
如果从句中有“itis+形容词”结构,也可以省略itis。
6.考查状语从句、宾语从句、简单句和并列句的句式结构。
如:
when引导时间状语从句意为“当……的时候”,引导宾语从句意为“什么时候”;if引导条件状语从句意为“如果”,引导宾语从句意为“是否”等。
一.状语含义:
修饰___词、_____词、____词或____,说明动作或状态特征的句子成分.
二.状语从句:
在主从复合句中做状语的从句。
结构为:
句子+引导词作状语。
如:
HehadlearnedalittleChinesebeforehecametoChina.
三.状语从句分类:
时间状语从句地点状语从句原因状语从句条件状语从句目的状语从句结果状语从句方式状语从句比较状语从句让步状语从句

类别
作用
例句
as
as表示“当……的时候”,往往和when/while通用,但它着重强调主句与从句的动作或事情同时或几乎同时发生。
ShecameupasIwascooking.(同时)
Therunnersstartedasthegunwentoff.(几乎同时)
when
(atorduringthetimethat)既可以表示在某一点的时候,又可表示在某一段时间内,主句与从句的动作或事情可以同时发生也可以先后发生。
Itwasrainingwhenwearrived.(指时间点)
Whenwewereatschool,wewenttothelibraryeveryday.(在一段时间内)
while
while意思是“当……的时候”或“在某一段时间里”。
主句中的动作或事情在从句中的动作或事情的进展过程中发生,从句中的动词一般要用延续性动词。
在when表示aperiodoftime时,两者可以互换。
Pleasedon’ttalksoloudwhileothersareworking.
Hefellasleepwhile/whenreading.Strikewhiletheironishot.(用as或when不可,这里的while意思是“趁……”)
注意事项:
a.as,when引导短暂性动作的动词。
例如:
Justas/Justwhen/WhenIstoppedmycar,amancameuptome.我一刹车,有一个人向我走来。
b.当从句的动作发生于主句动作之前,只能用when引导这个从句,不可用as或while。
例如:
Whenyouhavefinishedyourwork,youmayhavearest.
c.从句表示"随时间推移"连词能用as,不用when或while。
例如:
Asthedaywenton,theweathergotworse. 日子一天天过去,天气越变越坏。
