语法专题十一：并列句与状语从句
状语从句是比较重要的语法项目。《2017年普通高等学校招生全国统一考试大纲》附录语法项目表中将状语从句列为必考项。全国卷新课标Ⅰ对状语从句的考查一般在完形填空、语法填空和短文改错中，主要考查从句引导词的用法。
2015年高考全国卷Ⅰ没有考查状语从句。
2016年高考全国卷Ⅰ第43题（完形填空）考查了状语从句引导词Since /Although /As /If的选择。
2017年高考全国卷Ⅰ没有考查状语从句。
一、并列句
(一) 并列连词
①They co me from the same country，and they are good friends.
②I was glad to meet Jenny again, but I didn't want to spend all day with her.(2013·新课标卷Ⅱ)
③It must have rained last night, for it is wet all over.
④Yesterday, I forgot to pick my daughter up, so she waited in the kindergarten for nearly two hours.
⑤Would you like to leave or would you like to stay?
规律总结：
1．表示并列、顺承关系的并列连词有and。
2. 表示转折关系常用的并列连词有but, yet(然而), whereas(然而，但是), while(然而)等。
3．表示因果关系的并列连词有for, so等。
4．表示选择关系常用的并列连词有or, either ... or ..., not ... but, neither ... nor ...等。
(二) 祈使句＋and/or/otherwise句式
①Work hard and you will succeed.
＝If you work hard, you will succeed.
②Hurry up or we will be late.
＝If you don't hurry up, we will be late.
③A few more efforts and you will succeed.
＝If you make a few more efforts, you will succeed.
规律总结：
1．祈使句＋and＋陈述句＝If ...，＋主句。
2．祈使句＋or/otherwise＋陈述句＝If ... not ...，＋主句。
二、状语从句
英语中状语从句总共有九类，分别用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。状语从句是较复杂的语法项目，但是理解起来并不难。从本质上讲，状语从句就是利用不同的关联词语将几个分句连接起来，以表达分句之间的特定逻辑关系。例如：
①I have brought an umbrella because it is raining.(原因)
②I have brought an umbrella in case it rains.(目的)
③I have brought an umbrella so that I don’t get wet.(结果)
④I have brought an umbrella even though it’s not raining.(让步)
⑤You don’t need bring an umbrella unless it is raining.(条件)
因此，学习状语从句的关键是掌握引导九类状语从句的关联词，只要能记住关联词，一般都能识别是哪种状语从句，从而正确分析句子结构并理解句子意思。
下面分别对九大类别的状语从句进行举例说明：
（一）时间状语从句
时间状语从句表示时间。
引导时间的状语从句的常用引导词有：when, as, while, as soon as, while, before, after, since , till, until 等。
特殊引导词有：the minute, the moment, the second, every time, the day，the instant, immediately , directly, no sooner … than, hardly … when, scarcely … when等。
1.when/while/as/whenever
①When I went into the office, the teachers were having a meeting.
②While I was doing my homework, they came in.
③As time goes by, it's getting warmer and warmer.
④When/While/As I was walking down the street, I came across an old friend of mine.
⑤We shall go there whenever we are free.
规律总结：
(1)when既可引导一个持续动作，也可引导一个短暂动作，可用于主句和从句动作同时发生或从句动作先于主句动作。
(2)从属连词while引导的动作必须是持续性的，侧重主句动作和从句动作相对比。
(3)从属连词as可表示从句和主句的两个动作交替进行或同时完成，可译为“一边……(，一边……)”或“随着……”。
(4)如果主句表示的是短暂性动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作，此时when, while与as可互换使用。
(5)whenever是when的强势语，它描述的不是一次性动作，而是经常发生的习惯性动作，翻译成“无论何时”。
2.when的特殊用法
①He was about to go to bed when the doorbell rang.
②They were watching the World Cup when suddenly the lights went out.
③They had just arrived home when it began to rain.
规律总结：
when引导时间状语从句，意为“正在这时”，表示某件事正要发生、正在发生或刚刚发生时，突然发生另一动作。常见句型有：
①was/were about to do sth. when...
=was/were on the point of doing sth. when...
②was/were doing sth. when...
③had (just) done sth. when...
3．表示“刚……就……，一……就……”的常用表达
①The moment I heard the voice, I knew father was coming
②The boy burst into tears immediately he saw his mother.
③He had no sooner finished his speech than the students started cheering.
＝No sooner had he finished his speech than the students started cheering.(2011·辽宁高考)
④I had hardly got to the office when my wife phoned me to go back home at once.
=Hardly had I got to the office when my wife phoned me to go back home at once.
⑤Once you see him, you will never forget him.
规律总结：
(1)as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner ... than ..., hardly/scarcely ... when ...和once这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一……就……”。
(2)no sooner ... than ...，hardly/scarcely ... when ...的时态搭配：no sooner与hardly/scarcely后的句子谓语动词应用过去完成时，而than与when引导的句子谓语动词应用一般过去时。此外，当把no sooner和hardly/scarcely提到句首时，应用倒装语序。【注意】“一……就……”还可用on /upon doing 结构来表示。On arriving home he called up Lester.=As soon as he arrived home, he called up Lester.
4．before与since

高中英语状语从句讲解汇总 原因从句 除了下面A2，A3中所示各种类型外，这两种从句均可由as或because来引导。但是用as引导原因从句较为稳妥（参见A）；用because引导结果／原因从句较为稳妥（参见B）。 A 原因从句 1 由as／because／since 引导的原因从句： We camped there as／because／since it was too dark to go on． 我们在那里露宿是因为天太黑，不能再继续往前走了。 As／Because／Since it was too dark to go on，we camped there． [ 因为天太黑不能再继续往前走，我们就在那儿露宿了。 2 in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand． 既然你在这儿，你就帮我个忙吧。 As／Since／Seeing that Tom knows French，he’d better do the talking． 既然汤姆懂法语，最好让他来谈。 3 在as／since／seeing that意指以前共知的或共知的陈述时，可用if来代替： ~ As／Since／Seeing that／If you don’t like Bill，why did you invite him 既然／如果你不喜欢比尔，你为什么邀请了他 注意：if so的用法： —I hope Bill won’t come． —If so（＝If you hope he won’t come），why did you invite him —我希望比尔别来。 —如果这样（=如果你希望他不来），你为什么邀请了他 关于if＋so／not，参见第347节。 ~ B 结果从句由because或as引导： The fuse blew because we had overloaded the circuit． 保险丝烧断了，因为我们使线路超载了。 He was angry because we were late． 他生气是因为我们来晚了。 As it froze hard that night there was ice everywhere next day． 因为那天晚上冷得厉害，所以第二天到处都是冰。 ~ As the soup was very salty we were thirsty afterwards． 因为这汤很咸，后来我们渴得厉害。
语法专题一：定语从句 1. 定语从句的几个基本概念： 1) 先行词：即被定语从句修饰的名次或代词，通常位于定从的前面。 2) 先行词在从句中担当成份：根据不同成份，用相应的关系代词或关系副词。 3) 关系代词：即先行词在定从中作主、宾、表、定。 作主语：指物，则用that, which引导，且不能省略；指人，用that, who引导，不省略。 作宾语：即及物动词宾语和介词宾语：指物，用that, which引导，可省略； 指人，用that, who, whom引导，可省略。 注意：如将介词提到了定从之首，先行词指人，只能用whom; 指物只能用which。 作表语：一般指人、指物皆用that, 可省略。 作定语：指人、指物皆用whose,不省略。 4) 关系副词：即先行词在定从中作状语，指时间用when, 地点用where, 原因用why，亦 可用介词+which替代。 所谓作状语：即先行词不能直接放入从句中，需要有一个介词连接，而从句中却没有这个介词。 5) 非限制性定语从句：即用逗号与主句或先行词分开，用于补充说明。 (1) which: 用于指代先行词（物），或整个主句，不能省略。 (2) who / whom: 用于指代先行词（人），不能省略。 (3) all / some of + which / whom: 用于指代先行词的部分。 (4) as为关系代词，“正如、就像”的意思, 引导定从时可置于句首、句中或句末。 注意：在非限制性定从中，不能用that。 2. 一些特殊用法： 1) 一般只用that引导从句的情况： (1) 限制性定语从句中，当先行词被强调，如被any, every, each, few, little, no, some, the only, the very等修饰时； (2) 先行词是不定代词all, few, little, much, something, nothing, anything等时； (3) 先行词被序数词或形容词的最高级所修饰时； (4) 先行词既有人又有物时； (5) 当句中已有who时，为避免重复。 2) 一般只用which引导从句的情况： (1) 引导非限制性定语从句，指前面的某名词或它前面的整个主句时； (2) 引导介词、介词短语提前的定语从句时； (3）当先行词为集体名词时，着眼于整体，用which；着眼于各个成员，用who； (4) 替代某些固定短语中的指示代词，如this, that等, 引导定从。 3) 由as引导的定语从句的几种常见情况： (1) as引导非限制性定语从句，说明整个主句的内容，和which引导定语从句代替整个 句子的区别是：which不能放在句首，而as则可以；在句中，as有“正如”、“就象” 之意，而which则没有此意； (2）当先行词前有the same，such修饰时，或在“so / as…as”结构中，表示“那样…… 以致”，后用关系代词as引导限制性定语从句； (3) 在such…as结构中，as为关系代词，替代先行词，引导的是定语从句；在such…that 结构中，that为连词，引导的是一个完整的结果状语从句。

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, 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。when(at or during the time)既可以表示在某一点的时候，又可以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。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。
t 状语从句讲解和练习 状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当 。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语的位置比较灵活，可以位于句首、句末或句中。enough用作状语修饰形容词和副词时必须后置。 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，分别表示时间、地点、原因、目的、 结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解 和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词 和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day，the instant, immediately , dire ctly, no sooner … than, hardly …when, scarcely … when I didn’t realize how special my mother was until I became an adult. While John was watching TV, his wife was cooking. The children ran away from the orchard(果园) the moment they saw the guard. No sooner had I arrived home than it began to rain. Every time I listen to your advice, I get into trouble. 2．地点状语从句 常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories.
