英语语法口诀 第一部分定语从句 1.定语从句概述 a)定语从句起定语修饰作用，分为限定性和非限定性两种，非限定性通常有逗 号验证 I have plenty of friends who are from foreign countries. I have plenty of friends, some of whom are from foreign countries. b)先行词，关系词，定语从句，如此一线性 The man that instructed me is a famous expert. c)关系词分为关系代词和关系副词两种，关系代词作主宾表定，关系副词作状 语才行：关系词三大作用：1.代替先行词；2.引导从句；3.在从句中充当成分The murder was caught alive in the house where he killed three women. 2.三步法选关系词 a)首先找出先行词，带入从句看成分是其次，（主表宾定不合适，状语必然是， 用关系副词）再由先行词及其成分定关系词 I will never forget the day when I met the president. 3.关系代词的选用 a)人用that whom who。 b)which that 用于物 c)that 真是个人物，既充人又充物；既当宾又当主
d)whom 只做宾，which that who 既宾又主 e)whose 作定语（=名词+of which），不分人或物 The tall house whose windows face the south is my office. 4.关系副词的选用 a)先行词the time，需用关系副词时，用when 才可以 若关系词在从句中充当状语，则关系词应用when，the time +when（=on which）I will never forget the days when I lived with you happily. I will never forget the days which I spent learning English . b)先行词the place，需用关系副词时，where来效力 若关系词在从句中充当状语。则关系词应用where，the place+where（=in which） c)先行词the reason，需用关系副词时，why有用武之地 若关系词在从句中充当状语，则关系词应用why，the reason +why（=for which）d)When where why都可用“相应介词+which”来代替 Why=for which; where=on/in/at which; when=on/in/at which 5.某个关系词不能使用的情形和关系词的省略 a)介词后不用that，who，而用which，whom 引导定从的关系词如果在介词后作介词宾语，则关系词不能用that和who The train on which she was traveling was late. Who is the girl to whom you speak? b)逗号后that资格不够 c)限定性定从中关系词作宾或表，可去可留.注：在非限定性定语从句中，关系
原因状语从句的用法 原因状语从句表原因，以下逐一介绍高考中常见的原因状语从句的引导词： 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，最适合回答 why引导的疑问句。例如： I do it because I like it. 我做这件事是 因为我喜欢。 注意：“not ... because”结构中的not否定的是because引导的整个从句，有时也否定主句例如： The country is not strong because it is large. 国强不在大。I 2. since引导的原因状语从句一般放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。例如： Since you are free today, you had better help me with my mathematics. 既然今天你休息，你最好帮我补习数学。 注意： seeing (that)， now (that)， considering (that)， in that这几个词汇与since引导的原因状语从句意思相近，都表示“既然”。例如： Seeing (that) he refused to help us, there’s no reason that we should now help him. 他既然曾经拒绝帮助我们，我们现在没有理由要来帮助他。// Now (that) you are grown up, you should not rely on your parents. 既然你长大了，就不应该依靠你的父母了。// Considering (that) everyb ody is here, let’s begin our discussion. 既然大家都到了，我们就开始讨论吧。// In that he is ill, he feels unable to do it. 因为有病，他觉得做不了那件 事。注意： 1. considering 和 given 还可用介词。如： Considering his age, the little boy reads very well. 就他的年龄来说，这小孩读得 挺好的。 Given her interest in children, I am sure teaching is the right career for her. 考虑到她喜欢孩子, 我可以肯定教书是最适合她的职业。 2. 表示“因为”的连词不能与表示“所以”的 so 连用。如： 译：因为他病了，所以没有出席会议。 误：Because he was ill, so he didn’t attend the meeting. 正：He didn’t attend the meeting because he was ill. 正：He was ill so he didn’t attend the meeting 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，较为正式，位置较为灵活(常放于主句之前)。例如：As it is raining, you’d better take a taxi. 既然在下雨，你最好乘出租汽车。// As you are tired, you had better rest.
如何区分定语从句、宾语从句和状语从句？（附习题）| 虫虫讲英语 2018-12-02 14:52 「虫虫讲英语」老少咸宜的英语学习号——有时候，语法换一种方式讲，就听懂了。 如何区分定语从句、宾语从句和状语从句，是学生最常问我的问题之一。今天，我们通过青铜、白银、黄金、王者四级难度的例句，一起研究下怎样一眼辨别英语3大从句。 01 概念 3大从句的区别均在于前面两个字：定语、宾语和状语： 知道了这几个概念，这三种从句就很好理解了： >> 定语从句：作定语的从句，做adj.修饰先行词；
在这里，dog “狗子” 是先行词，即“走在定语从句前面的名词”；定语从句 that shits a lot 其中的 that，指 代了前面的 dog，告诉我们这是一条怎样的狗子：拉很多的狗子。 >> 宾语从句：作宾语的从句，放在动词或介词后面； 第一句，宾语从句为普通的陈述句，放在 think 这个动作后面，由连接词 that 引导。 第二句，宾语从句已经改成陈述句语序，原来人讲的话则是一般疑问句Do you let it go “你丫放不放手” ？该从句放在 depend on 的介词 on 后面，一般疑问句由 whether/ if 引导。 >> 状语从句：作状语的从句，给主句增加信息量。 状语从句，是3大从句中比较好记的一种：有个完整的主句，从句是提供更多信息的，比如上述例句告诉我们他为什么养狗。只要熟悉九大状语从句的引导词（← 戳可查看），几乎一眼就能辨别出状语从句。 02 当堂练习 现在，我们一起看几个句子找找感觉。请判断下列句子是定语从句，宾语从句还是状语从句？ >> 青铜 1. If it is fine tomorrow, I will visit you. 2. I helped an old man who lost his way.

状语从句 在复合句中担任状语成分的从句称为状语从句，修饰主句的谓语动词，形容词或副词，状语 说白了就是修饰动作的词或句，也可以理解成修饰谓语的词或句。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 , directly, 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. When , while, as 都可解释为“当```的时候”但侧重点有所不同。 1) When Eg: When I arrived home , I had a little rest. 注意点： when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be 可以省略。Eg: When (she was) walking along the street, she met her class teacher. 2) As As 除了表示“当```的时候”，还可表示为“一面``` 一面”，“随着” Eg: He sang as he danced.(一面 ```一面 ) You will grow wiser as you grow older.(随着) 3) While 表示“当 ``` 的时候” 强调主句的动作和从句的动作同时发生，从句一般用进行时， 从句动词必须是延续性动词。 Eg: While we were working, they were having a rest. While (they were) having a discussion, they got very confused. 注意点： while 有对比的含义，解释为“然而”。 eg: I prefer black tee, while he likes coffee. 1．until, not ? until 表示“直到 ```才” ,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。
对原因状语从句几个连词的区分 In the morning I didn’t need to get out early. I would always spend over an hour just surfing_______Internet. The same would happen at night. I didn’t go to bed ________I felt very tired and sleepy. Later I made a _________(decide) to develop a new habit because I didn’t like the feeling I had when_________(waste) time on the computer.

I am happy that I can decide when to turn on my computer and deal with emails and________to spend my time. 答案：the; felt; decision; waiting; which; relaxed; myself; as; for; how because, as, for, since这几个词都是表示“原因”的连词,语气由强至弱依次为：because→since→as→for;其中because, since, as均为从属连词,引导原因状语从句；而for 是并列连词,引导并列句. 1. because表示直接原因,它所指的原因通常是听话人所不知道的,其语气最强.常用来回答why的提问,一般放于主句之后,也可以单独存在.例如： (1)I stayed at home because it rained. 因为下雨我呆在家里. (2)Because Lingling was ill, she didn”t come to school. 玲玲因病,没有上学.

状语从句 一．分类： 种类连接词注意区别： 时间状语when/whenever/while/as/before/after/instantly /until/till/by the time/as soon as/hardly…when/directly /no sooner…than/the moment/the minute/immediately 有一些表示时间的名词短语也可用来引导时间状语从 句：the minute, the moment, every time, the first time 例：The moment he reached the country, he started his search. 他一到达这个国家，就开始他的探寻工作。 有一些表示时间的副词也可用来引导时间状语从句： directly 例：Directly the master came in, everyone was quiet. 校长一进来，大家就安静下来 as和when、while： as, when 引导短暂性动作的动词。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。从句表示"随时间推移"连词能用as，不用 when 或while。 till/until和not…till/until： Until可用于句首，而till通常不用于句首。 地点 状语 where//wherever where，表示某一个；wherever，表示任何一个。 原因状语Because/as/since/now that/for because和since、for、as、now that： because语势最强，用来说明人所不知的原因，回答why 提出的问题。当原因是显而易见的或已为人们所知，就 用as或since。由because引导的从句如果放在句末， 且前面有逗号，则可以用for来代替。但如果不是说明 直接原因，而是多种情况加以推断，就只能用for。now that都表示“既然”now that一定要是现在发生的，since 可以是现在，也可以是过去和现在。 条件状语if/unless/once/in case/as long as/on condition that 多用一般时态，如果表示一般将来的情况，就用一般现 在时，如果表示过去将来的情况，就用一般过去时。 目的状语(so) that,/in order that/for fear that/in case/lest so that和in order that后常接may, should, could, would 等情态动词 结果状语so…that, such…that 其规律由so与such的不同词性决定。such 是形容词， 修饰名词或名词词组，so 是副词，只能修饰形容词或 副词。so 还可与表示数量的形容词many, few, much, little连用，形成固定搭配。 比较 状语 Than/a s…as，not so/as…as/the more…the more 方式 状语 as if, as though, as, (just)as---so，as if 和as though引导的从句一般用虚拟语气。 让步状语Though/although/even if/even though/as，no matter what/who/which/how/when，whatever/whoever /whichever/however/whenever ，whether---or---（不管 ----都） as在让步状语从句中常用倒装形式；although和though 用正常语序，可和yet连用，但不可和but连用 时间状语从句： when (当……的时候) while (在……期间) as (当……的时候, 一边……一边……） before (在……之前) since (自从……以来) till/until (直到) hardly…when… (刚……就) as soon as (一……就……）after (在……之后) not…till/until（直到……才）no sooner…than…（ 刚……就)
大家一起来学语法状语从句 让我们大家一起学习语法, 学过动词时态再来研究形容词与副词, 限定词, 现在我们来学状语从句。大家可以把下列的资料copy然后粘贴在Notepad或word 里，根据你所知的英语资料，给下面材料进行增添和编辑。记住啊！可千万不要渗假信息在里面！要对学习有认真的态度, 才能真正学好英语。然后再把编辑好的文章贴在这里，让我们大家一起讨论学习。 状语从句 1 地点状语从句 地点状语从句通常由where, wherever 引导。 Where I live there are plenty of trees.我住的地方树很多。 Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。 2 方式状语从句 方式状语从句通常由as, (just) as…so…, as if, as though引导。 1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如： Always do to the others as you would be done by. 你希望人家怎样待你，你就要怎样待人。 As water is to fish, so air is to man. 我们离不开空气，犹如鱼儿离不开水。Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。 2）as if, as though 两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如： They completely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实，就仿佛它不存在似的。（与事实相反，谓语用虚拟语气。） He looks as if (as though) he had been hit by lighting. 他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。） It looks as if the weather may pick up very soon. 看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。） 说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如： He stared at me as if seeing me for first time. 他目不转睛地看着我，就像第一次看见我似的。 He cleared his throat as if to say something. 他清了清嗓子，像要说什么似
状语(adverbial)是句子的重要修饰成分。状语是谓语里的另一个附加成分，它附加在谓语中心语的前面，从情况、时间、处所、方式、条件、对象、肯定、否定、范围和程度等方面对谓语中心进行修饰或限制。在英语中，状语修饰动词、形容词、副词等的句子成分。 状语的功用：状语说明地点、时间、原因、目的、结果、条件、方向、程度、方式和伴随状况等。 状语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语来担当。其位置一般放在句末，但也可放在句首或句中。 副词是一种用来修饰动词，形容词，副词或全句的词，说明时间，地点，程度，方式等概念。 1.副词一般在句子中做状语. He speaks English very well. 他英语说得非常好.中的very是程度副词，用来修饰well。very well是修饰speak的程度状语。 2.不定式在句子中可以作目的状语。 I come specially to see you. 我专门来看你. 3.介词短语 Ten years ago, She bega n to live in Dalia n. 十年前，她开始住在大连。 The boy was praised for his bravery. 4.从句作状语 When she was 12 years old, she bega n to live in Dalia n. If I am not busy tomorrow, I will play football with you. 5.分词作状语 Havi ng had a quarrel with his wife, he left home in a bad temper 。 In hibited in one direct ion, it now seems that the Mississippi is about to take ano ther. 状语简介 概述 状语与定语相同的地方是，都是前者附加成分；不同的地方是，它是谓语里的附加成分，而定语是主语或宾语里的附加成分.从句子的层次上看，状语是在第二个层次和第三个层次里的成分，有时甚至是更低层次的成分.
一、状语从句分类及常用连词： 类别连词 状语从句when, whenever, while, as, before, after, since, till, once, as soon as,etc. 状语从句where,wherever 状语从句because, since, as, for, now that, etc. 状语从句so…that, so that, such…that, that, etc. 状语从句in order that, so that, that, etc. 状语从句if, unless, as(so)long as, etc. 状语从句though, although, even if, even though, however, whatever, as,etc. 状语从句as…as, so…as, than, etc. 状语从句as, as if, as though, etc. 二、相似连词的用法区别 1.when, while, as, while表时间，从句需用延续性动词，切不可用瞬间动词。 when表时间，从句既可以用延续性动词，又可以用瞬间动词。 as表时间，与when相似，但侧重强调主从句动作同点或同段进行。 when, while后可以接分词短语。 2.because, as, since, for 语气位置意义 because最强前或后“原因”；表客观因果关系；回答“”as较强前“由于”；把众人所知的事实当作理由since较弱前“既然”；就对方陈述的事实作为理由for最弱后“理由”；对某一事实进行推断的理由 注：上面所说的“前”，指从句在主句之前；“后”，指从句在主句之后。 3.so that, so…that, such…that so that“以便”、“结果”表目的和结果。注意：在从句中有情态动词表目的。无情态动词表结果。 so…that “如此的…以致于”表结果。该结构常见于： 1.so+形／副＋that 2.so+形＋a(an)＋单数名词＋that 3.so＋manymuch＋复数名词（不可数名词）+that such…that“如此的…以致于”表结果。该结构常见于： 1.such＋a(an)＋形＋名词＋that 2.such＋形＋复数名词／不可数名词＋that
状语从句 状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。 1. 时间状语从句 (1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如： When while as 的区别It was raining hard（rain hard 下大雨）when got to school yesterday. While he was doing his homework, the telephone rang. As he walked along（沿着走）the lake, he sang happily. He had learned a little Chinese before he came to China.
