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, in case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，as soon as，until，notuntil，before, after, since等；条件状语从句的连词有if，unless, in case, on condition that, provided (that), supposing, suppose (that)等；结果状语从句的连词有sothat(如此以至于), suchthat(如此以至于)等。2 考查固定搭配和习惯用法的连接词。如：no soonerthan，hardlywhen，scarcelybefore，the moment/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“it is形容词”结构，也可以省略it is。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：He had learned a little Chinese before he came to China.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 让步状语从句状语从句名称常用连词时间When, while, as,as soon as, hardlywhen, no soonerthan, scarcely.when, since(自从),once,whenever, before, after ,till, until, the moment(the minute, the second, the instant, immediately, directly,instantly,),by the time, every time, each time, as long as(=so long as)地点Where, wherever条件If, unless, once(一旦就),in case(that)（万一）,so long as(as long as),on condition that ,as far as(so far as)原因Because, since(既然),now that, as , ,seeing that(看到),considering that(考虑到)结果Such(a, an)that, sothat, so, so that, that目的So that in order that, for fear that, in case（以防，以免）让步Though, although, as, ever if= even though, whatever, whenever, wherever, however, whichever, whoever, whomever, no matter what, no matter when, no matter where, no matter how no matter which, no matter who, no matter whom, whether or not= whether or not(不管与否)比较Asas, not so/asas, morethan, lessthan方式As, just as, as if=as though练习题1.While I was walking along the street, I found many beatiful buildings ( )2.
