(最新实用)2020年高考英语语法专项突破训练专题14-状语从句
专题十五状语从句重难点分析状语从句是由从句担任状语，在句子中可修饰谓语动词（或其他动词）、形容词、副词或整个句子。
它可以用来表示时间、地点、条件、原因、结果、目的、让步、比较、方式等。
状语从句是一个较大的语法项目，也是近几年高考题中常见的重点考点。
高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考的热点，应做充分的准备。
同时对方式状语从句也应引起重视。
不同的状语从句所使用的连接词也各不相同。
如下表所示：一、时间状语从句1. while, when, as引导时间状语从句时的区别(1) while引导的状语从句中谓语动词必须是持续性动词。
谓语动词多为进行时或状态动词的一般时。
此时可与when互换。
如：Please keep quiet while/when others are studying. 当别人正在学习时，请保持安静。
(2) when除可指一段时间外，还可用来指时间点，等于“at the time”，即when引导的时间状语从句中的谓语动词可以是瞬间的，也可以是持续性的。
因此主句和从句的谓语可以是一般时、进行时或完成时。
如：When I went into the lab, the teacher was doing an experiment. (when不能换成while) 当我走进实验室时，老师正在做实验。
(3) as常可与when, while通用，但as强调“一边……一边……”。
如：As(When/While) I was walking down the street, I noticed a police car. 当我沿着大街散步时，我注意到一辆警车。
(4) when有时代替if，引导条件句，意为“如果，假如”。
如：I will come when(if) I am fine. 如果我有空，我就会来。
2. till, until引导时间状语短语或状语从句，用于否定句时，结构为not…until，主句谓语动词延续与非延续皆可，意为“直到……才……”；用于肯定句时，主句谓语动词需用延续性动词，表示“到……为止”。
高三英语 语法专项状语从句
领兑市安插阳光实验学校中学高三语法专项-状语从句(1)【考点分析】状语从句是每年高考必考的内容，在高考试题中加上其它从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。
1.时间状语从句由下列连词引导：when, while, as, before, after, once, till, until, since, as soon as, now that, hardly…when,scarcely…when, no sooner…than,有一些表示时间的副词（短语）或名词短语也可引导时间状语从句。
如：directly, instantly, immediately, by the time，the moment, the second, the minute, the instant, every time, each time, next time, the last time内容如下：①when, while, as引导的时间状语从句▲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。
She came up as I was cooking. (同时)The runners started as the gun went off. (几乎同时)▲when(at or during the time that )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。
It was raining when we arrived. (指时间点)When we were at school, we went to the library every day. (在一段时间内)When we arrived there, the film had already begun. (先后发生)▲while意思是“当……的时候”或“在某一段时间里”。

高考英语语法词汇专项突破：07聚焦逻辑主语与句子主语不一致的分词状语
高考英语语法词汇专项突破：聚焦规律主语与句子主语不全都的分词状语一般来说，分词作状语要求与句子的主语保持规律上的全都。
假如不全都，则用独立主格结构，或者是状语从句，信任这一点同学们都很清楚。
但是也有一些作状语的分词与句子的规律主语不全都，也是正确的句子，这样的分词被称为垂悬但不致病分词。
常见的状况有：与副词连用作评注性状语的分词；转变成介词的分词；转变成连词的分词。
一、作评注性状语的分词现在分词speaking与一些副词连用，意思是“……说”，generally (broadly/ frankly/ strictly/ honestly/ personally) speaking 一般地（泛泛地/ 坦率地/ 严格地/ 诚恳地/就个人来）说。
如：1. The limits of a person’s intelligence, generally speaking, are fixed at birth, but whether he reaches these limits will depend on his environment.一个人的智力极限，通常来说，诞生时就已经定型了。
但他是否能够达到这些极限则取决于他所处的环境。
3. Strictly speaking, I’m his stepfather, not his father.严格地说，我是他的继父，不是他的亲生父亲。
二、作介词的分词（一）judging from (by)… 从……推断；依据……来推断。
如：处排起的长队来看, 这部电影格外叫座儿。
（二）including 包括，包含。
如：1. There are 50 students in our class, including 15 girl students.包括十五位女生在内，我们班有五十位同学。
比较：There are 50 students in our class, 15 girl students included.（独立主格结构）2. All the railway officials,including the engine crew, had disappeared in the opposite direction. 全部铁路人员，包括机车组，都在对面消逝了。
高中英语语法专项—— 状语从句(九大状语从句详讲+配套练习)
语法专项2——状语从句【状语从句综述】由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。
一、时间状语从句1.表示时间的状语从句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner … than, hardly (scarcely) … when, every time等引导。
例如：When I came into the office, the teachers were having a meeting.当我进入办公室时，老师们正在开会。
He started as soon as he received the news. 他已得到这个消息，就出发了。
Once you see him, you will never forget him.一旦你见了他，你就不会忘记他。
No sooner had I gone to bed than I went to sleep.我一上床就睡着了。
2.when, while, as的区别这三个词都可以用作连接词，表示时间关系，但有所区别。
(1)when表示时间关系时，意思常常是“当(在)……的时候”。
主句和从句中的动作或事情可以同时发生，也可以先后发生。
例如：When we were at school, we went to the library every day.我们在求学的时候，每天都到图书馆去。
(2)while 用作连接词表示时间关系时，意思也是“当(在)……的时候”，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。
它有时可与when通用，但它只能指一段时间(a period of time)，而不能指一点时间的(a point of time)。

高考英语语法专项突破·高考真题分类状语从句【2013北京卷】30．I took my driving license with me on holiday，________I wanted to hire a car.A．in case B．even ifC．ever since D．if only【解析】in case以防万一，引导条件状语从句；even if纵然，即使，引导让步状语从句；ever since自以来，引导时间状语从句；if only要是就好了，常用于虚拟语气，表示一种强烈的愿望。
题干的意思是：我度假时随身带着驾照，以备我租车之需。
由句意可知正确答案为A项。
掌握连词的用法以及正确理解句意和前后的逻辑关系是解题关键。
【答案】A【2013天津卷】5．________ small，the company has about 1,000 buyers in over 30 countries.A．As B．IfC．Although D．Once【解析】句意：“尽管很小，但是这个公司在30多个国家有大约1 000个买家。
”根据句意及前后句的关系可知选择C项although“尽管”。
【答案】C【2013重庆卷】25．________we have enough evidence, we can't win the case.A．Once B．As long asC．Unless D．Since【解析】句意：如果我们没有足够的证据，我们就不能打赢这场官司。
分析题意可知，前后两句之间为条件关系。
A项意为“一旦”；B项意为“只要就”；C项意为“除非，如果不”；D项意为“自从”。
unless＝if...not，所以答案为C。
【答案】C【2013山东卷】26．Mark needs to learn Chinese ________ his company is opening a branch in Beijing. A．unless B．untilC．although D．since【解析】句意：马克需要学习汉语，因为他的公司将在北京开一个分公司。
本句中的“在北京开一个分公司”是“需要学习汉语”的原因，四个选项中引导原因状语从句的只有since。
unless意为“如果不；除非”，引导条件状语从句until意为“直到时”，引导时间状语从句；although意为“尽管，虽然”，引导让步状语从句。
【答案】 D【2013山东卷】28．________ I have to give a speech，I get extremely nervous before I start. A．Whatever B．WheneverC．Whoever D．However【解析】句意：每当我必须演讲时，在开始前，我都变得非常紧张。
whatever“任何事物，一切事物；无论怎样”，引导名词性从句或让步状语从句；whenever“每当；无论什么时候”，引导时间状语从句或让步状语从句；whoever“的人；无论是谁，不管是谁”，引导名词性从句或让步状语从句；however“不管怎样”，引导让步状语从句。
故只有whenever符合句意。
【答案】B【2013辽宁卷】24．One can always manage to do more things，no matter ________ full one's schedule is in life. A．how B．whatC．when D．where【解析】句意：无论一个人的生活日程有多么满，他总能设法做更多的事情。
本句中“no matter＋疑问词”结构引导让步状语从句，因为要修饰空格后的形容词full，故用how，no matter how意为“无论多么”。
no matter what意为“无论什么”；no matter when意为“无论何时”；no matter where意为“无论何地”。
【答案】A【2013江苏卷】28．In the global economy，a new drug for cancer，______ it is discovered，will create many economic possibilities around the world.A．whatever B．whoeverC．wherever D．whichever【解析】通过分析句子结构可知，________ it is discovered在句中作状语。
在这个状语从句中，不缺少构成句子的主要成分，所以引导词只能在从句中作状语，从而选择具有副词性质的词成为答题的关键。
分析四个选项可知符合条件的只有C项(wherever)，故答案选C。
句意：在全球经济中，无论是在哪儿发现一种治疗癌症的新药物，这都将会在全球产生很多经济方面的可能性。
【答案】C【2013湖南卷】23．You must learn to consult your feelings and your reason________you reach any decision. A．although B．before C．because D．unless【解析】although“虽然，尽管”，引导让步状语从句；before“在之前”，引导时间状语从句；because“因为”，引导原因状语从句；unless“除非”，引导条件状语从句。
题干的意思是：“做任何决定之前，必须学会尊重自己的情感与理智。
”空格前后的时间先后意味较为明显，所以答案为B。
【答案】B【2013安徽卷】23．It's much easier to make friends ________ you have similar interests.A．unless B．whenC．even though D．so that【解析】本题需要根据题干的意思和前后两句之间的逻辑关系来判断使用哪个关联词。
unless除非，表示相反的条件；when表示时间(有时兼有条件)；even though即使，表示让步；so that以便，表示目的或结果。
句意：当你们有相似的兴趣时，就更容易成为朋友。
此处为时间兼条件，故选B项。
【答案】B【2013四川卷】7．He is so busy. He cannot afford enough time with his son________he wants to.A．even if B．as ifC．because D．before【解析】本题四个选项都为常见连词(词组)，even if即使，as if好像，because因为，before在之前。
题干的意思是：他如此忙碌，即使想抽出充足的时间陪陪儿子也做不到。
even if在此引导让步状语从句，符合题意。
【答案】A【2013江西卷】28．She says that she'll have to close the shop________business improves.A．if B．unlessC．after D．when【解析】句意：她说如果生意不见好转，她就不得不关闭这家商店。
unless意为“除非；如果不”，符合语境。
【答案】B【2013陕西卷】18．I have heard a lot of good things about you________I came back from abroad.A．since B．untilC．before D．when【解析】从题干中的“have heard”可知是“已经听说”，所以应该是“自从我回来”，因此要用since引导时间状语从句。
题干的意思是：“自从我从国外回来，我听到了很多关于你的好消息。
