1、1专题十五 状语从句分析全国各省市近 5 年中考真题可知，中考对状语从句的考查比重较大。主要考查状语从句的时态，特别是 if 引导的从句。考查连接状语从句的连词，常考：if, since, until, or, unless when 和while 的区分。21、状语从句的定义 用来修饰动词和形容词，以表明动作发生或状态存在的时间，地点，原因等等的句子叫做状语从句。二、状语从句的分类 1.、时间状语从句 时间状语从句表示时间，引导词有：when, while, as, till, until before, after, since 等。时间状语从句的引导词所表示的意思不尽相同，要注意把握不同
2、引导词所表示的不同时间关系，以及它在具体句子中对应的时态、语态等问题。 注意：(1)as(在时候，因为)，since(自从，因为)，它们可以引导时间从句，并强调主句和从句的动作同事发生。并且 while 有时还可以表示对比。(2)when(当的时候)，引导的从句的谓语动词可以是延续性动词，也可以是瞬间动词。从句动作可与主语动作同事发生，也可在其后发生。(3)when 和 while 的区别还在于：while 引导的时间状语从句多用于进行时态，而 when 引导的时间状语从句多用于一般时态。(4)as 译作 “一边一边”、“随着”，侧重主句和从句的动作同时发生。有时可与when，while 通用
3、。2.till 或 until 引导的时间状语从句 till，until(直到才)：一般情况下两者可以互换，但是在强调句型中多用 until。till 不可以在句首，而 until 可以放在句首。 注意：如果主句中的的谓语动词是瞬间动词时，必须用否定形式;如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。3.since 引导的时间状语从句 Since(自从)：引导的从句的谓语动词可以是延续性的动词，也可以是瞬时动词。一般情况下，从句谓语动词用一般过去时，而主句的谓语动作用现在完成时。但在 It is+时间+since 从句的句型中，主句多用一般现在时。4.由 bef
4、ore 和 after 引导的时间状语从句 注意：(1) before(在之前)：引导的从句不再用否定的谓语。(2) 当主句用将来时，从句总是用现在时;如果 before 引导的从句谓语用的是过去时。则主句动词多用过去完成时，这样以便体现动作发生的先后。(3) after(在之后)：表示主句动作发生在从句动作之后。如果主句用的是过去时，则从句多用过去完成时。(4) 由 as soon as ,immediately, directly ,instantly, the moment, the instant, the minute,等引导的时间状语从句：这些连词都表示“一就”注意 3hardly
5、(scarcely，rarely)when,before，no sooner than 相当于 as soon as 之意。主句用过去完成时，从句用一般过去时态。当 hardly，scarcely, rarely 和 no sooner 位于句首时，主句应用倒装语序。2、原因状语从句 原因状语从句表原因，常见的引导词有：because(因为)，since(既然)，as(既然)，for(因为) 1. because 引导的原因状语从句一般放于主句之后，because 表示直接原因，语气最强，回答 why引导的疑问句必须使用 because。注意 ：1.“notbecause” 结构中的 not
6、否定的是 because 引导的整个从句，2.Since 引导的原因状语从句一般位于主句之前，表示已知的、显然的理由。通常被翻译成“既然”，较为正式，语气比 because 弱。 3.as 引导原因状语从句时表示附带说明的“双方已知的原因”，语气比 since 弱，较正式，位置较灵活，常放于主句之前。4. for 引导的原因状语从句并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明，for引导的原因状语从句只能放于主句之后并且必须用逗号将其与主句隔开。三、条件状语从句 引导条件句常用的连词有 if(如果)，unless(如果不，除非)等，条件状语从句和时间状语从句一样，表示将来要用一般
7、现在时态。(1)if 引导的条件状语从句表示将来时，要用一般现在时代替，主句仍使用一般将来时态。 (2)将 if 引导的宾语从句和状语从句进行混淆考查，宾语从句中的 if 表示“是否”，可以使用一般将来时。 四、让步状语从句让步状语从句表示“虽然，即使，尽管”。引导词有 although，though，even though, even if 都表示“虽然，即使，尽管 ”之意。主句中不能用 but，但可用 yet、 Though 和although 语气较弱(其中的 though 比 although 通俗，不如 although 正式)，even if 和 even though 带有强调意
8、味而显得语气更强。注意 though 引导的让步状语从句的用法比较特殊，它可以倒装，也可以不倒装。5、地点状语从句 地点状语从句常由 where 和 wherever 引导，通常可置于主句之前或之后。6、目的状语从句 目的状语从句通常由 so that, in order that 引导，所引导的从句通常放在主句后面。目的状语从句中的谓语常含有 may (might),can (could),shall ,will 等情态动词。7、结果状语从句 结果状语从句常由 so that, sothat, suchthat 等引导，放在主句之后，sothat 与 suchthat 句型在一定条件下可转换
9、。注意 so that 引导结果状语从句和目的状语从句的辨别 4so that 从句之前有个逗号的常为结果状语从句，因表示某一行为带来的结果，从句中的时态常为过去式;so that 从句中有 may(might)，can(could)，should, will 等情态动词的通常是目的状语从句。8、比较状语从句 1. 比较状语从句常由 asas，not so(as)，than 引导。比较从句部分常为省略句。2. 通常把 the morethe more结构也归为比较从句，意为：“越越”。9、方式状语从句 1.方式状语从句常由(just)as(像)，as if/though(好像)引导，表示动作的
10、方式。2.as if/though 引导的状语从句，若描述非事实情况，常用虚拟语气。1.（2017 连云港市）一 Mum，_shall we have lunch?We will have it when your dad_.A when；returns B where returns Cwhere；will return Dwhen；will return2. （2017 昆明市）Could you please give me your e-mail address _you go?A. as soon as B. before C. after D. until3.2017 福州市一 H
