(完整版)英语状语从句汇总整理版
英语中的九大状语从句状语从句在主从复合句中修饰主句中的动词、形容词或副词等，按意义可以分为时间、地点、原因、目的、结果、条件、方式、比较、让步等状语从句。
一．时间状语从句。
通常由从属连词when, whenever, as, while, before, after, as soon as, till, until, since, once (一旦), hardly……when…, no sooner…….than…; 等引导。
例如：The cyclist started just as the lights changed to green.Whenever we met with difficulties , they cam to help us.He didn’t leave his office until he had finished the day’s work.应注意的问题1．在时间状语从句中，通常要用动词的一般现在时态表示一般将来时态，用一般过去时态表示过去将来时态。
但when 引导一般疑问句或名词性从句时不受上述语法规则的限制，因此，应该加以区分。
例如：When China will enter WTO depends on the bilateral (双边的)joint efforts.Once you understand the rules of the game, you’ll enjoy it.2.when , while, as 的不同用法。
一般说来，当主、从句的动作是同时发生的事，三者可以换用。
when 既可以引导一个持续动作，也可以引导一个短暂动作，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；while 引导的动作必须是持续性的，强调主句和从句的动作同时发生，往往侧重主句和从句动作的对比；as 用于引导“在某行为的继续中发生某事”的“继续之行为”，所以多与过去进行时连用，翻译成“一边……一边……”或者表示动作的变化，翻译成“随着……”。

(完整版)定语从句(完整版)
定语从句定语从句及相关术语1. 定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。
2. 关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。
关系代词有that, whi ch, who, whom, whose, as等；关系副词有where, when, why等。
关系词常有3个作用：1,引导定语从句。
2,代替先行词。
3 ,在定语从句中担当一个成分。
注：关系代词有主语.宾语之分。
一般whom作为宾语。
4. 定语：定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语或句子，汉语中常用’••…的'表示。
主要由形容词担任。
此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任.单词作定语时通常放在它所修饰的词之前，作前置定语。
短语和从句作定语时则放在所修饰的词之后，作后置定语。
先行词：被定语从句修饰的名词、代词称为先行词。
（一）限定性定语从句一、关系代词（在句中作主语、宾语或定语）1. that既可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语也可以省略。
［eg : this is the book （which ） you want。
］而且，如果which在从句中作不及物动词+介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括当先行词是anyt hing, everything, nothing , none 等不定代词时，或者是由every, any, all, some, no, little, few, muc h等修饰时等，这时的that 常被省略还有先行词前有序数词或形容词最高级修饰时，或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时，都只能用that4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语5. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物，当它引导的从句修饰物体时，可以与of which调换，表达的意思一样。
(完整版)定语从句语法详解
定语从句语法专题（Attributive Clauses）教案一. 定语从句的概述:1.定语从句：在复合句中，修饰某一名词或代词的从句叫定语从句。
在句中做定语，被修饰的名词或代词，叫做先行词。
从句通常放在先行词之后，由关系词（关系代词或关系副词）引导。
其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。
eg She is the girl（who got the first prize.）girl先行词who充当从句主语, 从句做定语修饰girlThis is the boy who broke the window.这就是打破窗子的孩子。
the boy是先行词, who broke the window是限制性定语从句, 明确指出theboy是打破窗子的那个孩子,who 在从句中充当主语That is the house where he lived ten years ago.He is the man who/that lives next door.He is the man who I want to see.先行词关系词定语从句复合句: 是由一个主句和一个或一个以上的从句构成的句子, 复合句中的主句和从句都具有完整的的主语和谓语, 主句是复合句的主体, 可以独立存在, 从句需要有一个连词引导, 是修饰说明主句的, 不能独立存在, 根据在句中的不同作用, 从句可以分为三类: 定语从句, 名词性从句, 状语从句。
二. 引导定语从句的关系词有两大类:1.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。
关系代词: that, who, whom, whose, which, as（主, 宾, 定）关系副词: when, where, why.（状语）2.关系词的作用:（1）引导定语从句, 在先行词和定语从句之间起连接作用；（2）代替先行词在句中充当成分。

定语从句(完整版)
定语从句(完整版)定语从句是用关系代词或关系副词引导的从句，它的作用是修饰主句中的名词性成分，相当于形容词。
关系词包括关系代词和关系副词，常用的关系代词有that、which、who、whom、whose、as等，而关系副词则有where、when、why等。
关系词有三个作用，即引导定语从句、代替先行词、在定语从句中担当一个成分。
需要注意的是，关系代词有主语和宾语之分，其中whom通常作为宾语。
定语是用来限定、修饰名词或代词的，它可以由形容词、名词、代词、数词、分词、副词、不定式以及介词短语来担任，甚至可以由一个句子来担任。
在汉语中，我们通常用“……的”表示定语。
单词作定语时通常放在它所修饰的词之前，作前置定语；而短语和从句作定语时则放在所修饰的词之后，作后置定语。
被定语从句修饰的名词或代词称为先行词。
限定性定语从句有两种形式，一种是由关系代词引导的，另一种是由关系副词引导的。
关系代词that既可代表事物也可代表人，which则只能代表事物。
在从句中，that和which可以作主语或宾语，而that在从句中作宾语时常常可以省略关系词。
如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前面，但有些例外。
需要注意的是，代表物时多用which，但在带有特定词语的句子中，如anything、everything、nothing、none等不定代词时，或者是由every、any、all、some、no、little、few、much等修饰时，应该使用that而不是which。
此外，当先行词前有序数词或形容词最高级修饰时，或先行词就是序数词或最高级时，或者先行词中既有人又有物时，也应该使用that，而不是which。
