高中英语状语从句用法详细解析
高中英语状语从句用法详细解析之五兆芳芳创作一、定义：在句中作状语的从句是状语从句，修饰主句中的动词、形容词或副词等.状语从句由从属连词引导，从属连词在句中不充当句子成分，只起连接作用，状语从句放在句首时，要用逗号，放在句尾时不必.二、分类按照意义上的不合，状语从句可分为：①时间状语从句②地点状语从句③原因状语从句④目的状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从句⑧方法状语从句⑨比较状语从句三、时间状语从句（一）引导时间状语从句的连词有：as, when(whenever), before, after, as soon as,until(till), since, every time, once.（二）、“as” as, when, while都有“当……的时候”，可以互用When she was a child.While she was a child.

从句(语法)
英语从句分类与解析从句是相对于主句而言的，即它是从属于某一个主句，而不能单独作一个句子。
在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句，包括时间、条件、结果、目的、原因、让步、地点、方式等）。
主语从句用作主语，如：：That the earth is round is true．地球为圆的是真实的。
宾语从句用作宾语。
如：Do you know where he lives?表语从句用作表语，如：My opinion is that you should not go alone．我的意见是你不应单独前往。
同位语从句用于解释说明前面的名词。
如：The fact that the earth is round is true．地球是圆的的事实是真实的。
（that从句用于解释说明the fact）定语从句相当于一个形容词，用于修饰前面的名词。
如：The student who answered the question was John．回答问题的学生是John．状语从句相当于一个副词，如：When it rains，I usually go to school by bus．天下雨时，我通常坐公共汽车上学。
（时间状语）If he comes tomorrow，you will see him．如果他明天来，你就可以看见他。
（if 引导的条件状语从句，其结构为：if ＋状语从句，＋主句）。
要注意在状语从句中有一个规则是“主将从现”，即主句是将来时，则从句要用一般现在时表示将来。
He returned home to learn his daughter had just been engaged．他回家后得知女儿刚刚订婚了。
（结果状语，结果状语只是仅限于learn（得知），find（发现），see，hear，to be told（被告知），make（使得）等具有界限含义的动词。

2023年高中英语语法：名词性从句用法详解及强化练习分析
2023年高中英语语法：名词性从句用法详解及强化练习分析名词性从句分类简述名词性从句，就是指其作用相当于名词的从句，它包括主语从句、表语从句、宾语从句和同位语从句。
一、主语从句1. 引导词：主语从句就是在复合句中用作主语的从句，引导主语从句的引导词主要有三类：一是that;二是whether;三是那些可以用作疑问词的词语，如what, who, which, when, where, how, why 等。
如：That we shall be late is certain. 我们要晚了，这是确定无疑的。
What he says is not important. 他说的话并不重要。
Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。
2. 形式主语：有时为了避免句子显得“头重脚轻”，可用it作形式主语放在句首，而把真正的主语放在句末。
如：It’s a pity that he didn’t come. 很遗憾他没来。
It was uncertain whether he could come or not. 他是否会来还不肯定。
这三句句首的it均为形式主语，相应的真主语分别是that he didn’t come / what she did / whether he could come or not。
二、表语从句表语从句就是在复合句中用作表语的从句。
一般说来，可用于引导主语从句的引导词也可用于引导表语从句，如that, what, who, which, when, where, how, why, whether等。
如：My idea is that we should do it right away. 我的意见是马上就干。
That is what he meant. 这就是他的意思。
The problem is how we can find him. 问题是我们如何找到他。
英语定语从句语法解析
英语定语从句语法解析语语法是针对英语语言进行研究后，系统地总结归纳出来的一系列语言规则。
英语语法的精髓在于掌握语言的使用。
下面店铺带来英语定语从句语法解析，欢迎阅读！英语定语从句语法解析篇11.先行词为all, anything, something, nothing, everything, much, little, none等不定代词时，关系代词一般只用that，不用which。
在大多数情况下that可以省略.Please tell me everything you know about the matter.Thats all we can do at the moment.2.as引出的限制性定语从句在such as的结构中as可作关系代词，引出限制性定语从句。
有时和same连用，在从句中可作主语、宾语或表语等。
Such people as were recommended by him were reliable.Ive never seen such a talented young man as he is.I have the same trouble as you .3.as引出的非限制性定语从句as可作关系代词引出非限制性定语从句，代替整个主句，通常译为(正)如一样，(正)象一样等。
as引导的从句一般用逗号与主句隔开，可以位于主句的前面、中间或后面.I live a long way from work, as you know.She did not, as her friend had feared, break down.As is generally accepted, economic growth is determined by the smooth development of production.4.分隔式定语从句定语从句一般紧跟在先行词之后，但有时会被其他句子成分与先行词隔开，从而构成分隔式定语从句。
英语从句分类与解析
英语从句分类与解析主句和从句的划分方法是相同的。
句子的成分从谓语动词处来划分比较容易。
谓语动词前面的部分是主语，后面常接宾语，修饰谓语动词的是状语，修饰主语、宾语的是定语，若谓语是系动词，则系动词后的部分是表语。
如：从句是相对于主句而言的，即它是从属于某一个主句，而不能单独作一个句子。
在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句，包括时间、条件、结果、目的、原因、让步、地点、方式等）。
一、名词性从句引导这些名词性从句的关联词包括:从属连词that, if, whether;连接代词who,whoever,whom,whomever,which,whichever,what,whatever,whose;连接副词where, when, why, how。
其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分.注意：1.从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语从句。
whether可与or(not)连用, 而if不可以。
I don't know whether (if) she is at home. Whether she comes or not makes no difference.2.that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。
that可省略, what则不可省。
He always means what he says. She suggested (that) he do it at once.3.同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。
语法精讲——从句的辨析
一、弄清复句的概念。
复句是指“主句+从句”。
英语中共有：三种从句类型：状语从句，定语从句和名词性从句。
从句的构成：从句的标志词+陈述句。
从句存在的规则：两句并存有且必须有一主一从之分。
标志词的使用规则：两句并存有且仅有一个从句的标志词。
二、了解如下三大从句的功能解析。
定语从句：（整个从句在主句中充当一个定语）构成：the+先行词（被修饰名词）+关系词+陈述句。
如何判断是一个定从：只要主句中有一个名词或整个主句在后面的从句中充当一个逻辑意思成分，该从句即为定语从句。
如何选择关系词：看从句缺少什么成分，指什么。
关系词的功能：who（定从中做主语，指人）whom（定从中做宾语，指人）that（定从中做主/宾语，指人/物）whose（定从中做定语，指人/物）which（定从中做主/宾语，指物）as（整个主句在从句中做主/宾，从句中常含有know/see/expect 的标志，且此定从常可置于主句之前，译为“正如…样”）when（定从中做时间状语）where（定从中做地点状语）why（定从中做原因状语）☆翻译原则：先译定从加“的”再译被修饰名词。
名词性从句：（在一个句子中的名词性成分——主语、表语、宾语、同位语处出现的句子）构成：连词+陈述句分类：主语从句，表语从句，宾语从句，同位语从句。
如何选择连词：只要判断一个从句中缺何成分，指什么。
连词的各个功能如下：that（不做任何成分，没有任何实意，只陈述事实，宾从中可省）who（做主语，指人，译为“谁”）whom（做宾语，指人，译为“谁”）whose（做定语，指人，译为“谁的”）which（做定语，指物，译为“哪一个”、“哪一些”可和of连用表范围指人）what（做主、表宾，指物，译为“什么”或“是…的”）when（做时间状语，译为“何时”）where（做地点状语，译为“哪里”）why（做原因状语，译为“为什么”）how（做方式状语，译为“怎么”“怎样”）if（是否，只用于及物动词的宾从中）whether （是否，可用于一切名从中常和or not 连用）☆翻译原则：是按词序不变。
考研英语语法(从句)详细解析总结(含例句)
考研英语语法（从句）详细解析总结（含例句）(一)英语从句的原理1.我们已经学习过句子的成分【参考句子成分讲义】当一个完整的句子A成为另一个句子B的某一成分时，A就变成了从句●eg. I know that you are hard-working！我知道你们很努力●完整的句子A { you are hard-working } 就叫做从句，在主句 B [I know A]中作宾语➡️A随从/服从B2.英语的三种句子●简单句：不能再拆分的句子【参考简单句讲义】●复杂句：也叫做并列句，两个句子不分主次，仅仅逻辑关系词连接and、but、however，，，●eg. I like apples，and he likes bananas. = He likes bananas，and I like apples.●复合句：主从复合句，主句 + 从句，两个句子有主次关系(二)英语从句的分类所以有哪些句子成分就会有哪些从句类型：除了英语的核心动词之外，其他所有句子成分都可以有从句1.①形容词从句 = 定语从句 = 关系从句➡️英语从句中最重要的；内容最多的；最难的一类从句●概念●对某个人或者事物进行描述，具有形容词性质➡️形容词性从句●在句子中充当定语这个成分，起修饰作用➡️定语从句●构成往往需要关系词来引导➡️关系从句●形容词从句的思维方式●中文思维：形容词都放在被修饰词之前，即形容词/句子 + 的eg. 好吃的苹果；努力学习的他们●英语思维●单个词修饰时，也放在被修饰词之前eg. a tasty apple●用一句话来修饰时，就需要在被修饰词后面 + 一个与它有关系的词 + 另一个句子，即先行词 + 关系词 + 定语从句●思维对比：这也是我们在翻译时不能逐字逐句顺序进行的原因，定语从句就需要逆序先翻译●中文：兔子在吃一根我买来的胡萝卜【前置】●英语：兔子在吃一根胡萝卜（胡萝卜的关系词）我买的【后置】The rabbit is eating a carrot that I bought.●形容词从句的构成：关系词（引导定语从句）●关系代词：引导词起指代、替代的作用●方法：陈述句语序中，被修饰词更换为关系代词➡️把关系代词放到开头，就变成了从句●that（那）：The rabbit is eating a carrot that I bought.I bought that →that I bought●who（主语）：The student who is reading is my friend.who is reading →who is reading●whom（宾语）：The student whom I taught is my friend.I taught whom →whom I taught●whose（ta的）：The student whose bag is pink is my friend.whose bag is pink →whose bag is pink●which（那个）：The student which is reading/I taught is my friend.which is reading/I taught which →which is reading/I taught●that & which：指代人或物（主语宾语都可以），经常可以互换●先行词唯一：that●eg. The rabbit ate the biggest carrot that I 've ever seen. 兔子吃了我见过最大的胡萝卜●the biggest已经限定了先行词是唯一的，所以只能用that●先行词多选一：which●eg. The rabbit is eating a carrot that/which I bought.●我买了很多根胡萝卜，兔子吃的只是其中随便一根●关系副词：引导词的词性是副词关系副词 = 介词 + 关系代词●where（地点）：This is the place where I study.●why（原因）：This is the reasin why I study.●when（时间）：That was the day when I met him.●形容词从句的限定性和非限定性●通过前面的学习，大家已经明白了定语从句的主要功能就是修饰限定范围，所以限定性和非限定性的区别即：是否限定了先行词的范围/性质●限定性定语从句●上述例句均为限定性定语从句：全部都限制了先行词的范围●非限定性定语从句：通常有逗号隔开，作插入语补充信息●eg. I read the book，which is on the desk. 我读了本书，那本书在桌子上（有种接着说，补充说明的意思）●eg. My head，which is big，is useful when it rains. 我有大头下雨不愁（作插入语补充信息，即使删去也不影响原句子完整）●eg. Rabbits eat carrots， which is not surprising. 兔子吃胡萝卜，这事不稀奇（甚至可以指代一个完整的句子进行修饰）2.②名词从句●引导词：相当于一个信号告诉你“那么接下来从句要开始咯！”注意：引导词在从句开头；从句是陈述句语序●that：确定信息●whether；where；when；how；who；what：不确定信息●主语从句：将句子中的主语变成从句的形式●正常语序：主语放在句子最开头●eg. That rabbits eat carrots is obvious.●eg. Whether rabbits eat carrots is obvious. 是否吃●eg. Where rabbits eat carrots is obvious. 在哪吃●eg. When rabbits eat carrots is obvious. 什么时候吃●eg. Who eats carrots is obvious. 谁吃●eg. What rabbits eat is obvious. 吃什么●eg. How rabbits eat carrots is obvious. 怎么吃●形式主语：it指代主语从句，it本身没有什么意义【翻译时，可以拆成两句或是倒序先翻译主语从句】英语句子的主语从句过长就会头重脚轻，所以会改个形式说出来●eg. It is obvious that rabbits eat carrots. 很明显，兔子吃胡萝卜/兔子吃胡萝卜这事儿很明显●eg. It is obvious whether rabbits eat carrots.●可自行练习改写上述例句●表语从句：将句子的表语变成从句的形式●eg. The reason is that you need to study.●eg. It feels that you like me.●同位语从句：将句子的同位语变成从句的形式●一般修饰抽象名词：the fact；the idea...●eg. The question that/whether rabbits eat carrots is interesting.●宾语从句：从句作句子的宾语●确定信息&不确定信息●eg. I know that rabbits eat carrots.●eg. I know whether/where/... rabbits eat carrots.●宾语从句引导词that往往可以省略，注意判断●eg. I know rabbits eat carrots.●宾语从句的否定●在谓语动词前否定，而非在从句中，否则会有句意的改变●eg.

高中语法解析从句的分类与用法
高中语法解析从句的分类与用法高中语法解析：从句的分类与用法引言：语法是语言的基础，而从句作为句子的一个重要成分，在阅读和写作中起着关键的作用。
在高中语法学习中，对于从句的分类和用法的准确理解和掌握是提高语言能力的关键之一。
本文将从句子结构、从句的分类以及从句的用法三个方面进行解析，帮助读者更好地理解和运用从句。
一、句子结构中的从句从句是一个可以独立成句但在主句中起到名词、形容词或副词作用的句子，它有自己的主语和谓语动词。
从句的存在使句子结构更加丰富多样，起到了丰富句子含义和表达复杂思想的作用。
1. 名词性从句：名词性从句在句子中作主语、宾语、表语或同位语。
常见的名词性从句包括主语从句、宾语从句、表语从句和同位语从句等。
例如：- 主语从句：What he said is true.（他说的是真的）- 宾语从句：I don't know where he went.（我不知道他去了哪里）- 表语从句：The fact is that they lost the game.（事实是他们输了比赛）- 同位语从句：I heard the news that she got the scholarship.（我听说她获得了奖学金）2. 定语从句：定语从句用来修饰一个名词或代词，并对其进行进一步解释或限制。
定语从句通常由关系代词（that, who, whom, which等）引导，并放在被修饰的名词或代词之后。
例如：- The book that I bought yesterday is very interesting.（我昨天买的那本书非常有趣）3. 状语从句：状语从句用来修饰一个动词、形容词或副词，表示时间、原因、条件、目的、结果等关系，并对主句进行补充说明。
常见的状语从句包括时间状语从句、原因状语从句、条件状语从句、目的状语从句和结果状语从句。
例如：- 时间状语从句：After she finished her homework, she went to bed.（她做完作业后就去睡觉了）- 原因状语从句：He failed the exam because he didn't study hard.（他考试不及格是因为他没有用功学习）- 条件状语从句：If you come early, we can have lunch together.（如果你早点来，我们可以一起吃午饭）- 目的状语从句：She studied hard so that she could pass the exam.（她努力学习以便能通过考试）- 结果状语从句：He was so tired that he fell asleep immediately.（他太累了，结果立刻睡着了）二、从句的分类与用法从句根据从属关系和在句中的作用可以分为几种类型，并在句子中扮演不同的角色。

when用于先行词指时间时；that多指物，有时也指人，在定语从句中作主语或宾语。
本句story是物，引导词在从句中做主语，需用连接代词that；根据句意结构，可知选C。
3．When we speak of culture, we mean a way of life_________ a group of people have in common.A．what B．who C．where D．that【答案】D【解析】【详解】句意：当我们说起文化的时候，我们指的是一群人共同拥有的生活方式。
考查定语从句的引导词。
根据句意：当我们说起文化的时候，我们指的是一群人共同拥有的生活方式。
逗号后面的句中是含有定语从句的复合句，先行词是 life，表示“物”，用引导词 that，在从句中做宾语。
what 不能引导定语从句。
先行词是“人”，引导词常用 who。
where 在定语从句中做地点状语。
故选D。
【点睛】引导定语从句的关联词包括关系代词和关系副词。
(完整版)高中英语语法总结-名词性从句
名词性从句在句子中起名词作用的句子叫名词性从句（Noun Clauses）. 名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句.第一节知识点讲解顾名思义,主语从句在句子中作主语。
有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部,前面用形式主语it代替。
从句作主语时,谓语动词一般为单数形式。
如：What I saw was beyond any verbal description。
That his hair was turning grey worried him a bit。
Why the company denied the contract is still unknown。
When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing。
It remains to be seen whether the new novel will be well received。
Tips：主语从句的that绝对不能省去。
因为句子是不能做主语的，故用that引导.若去掉则没有了主语，而宾语从句的that可省。
主语从句:That he is right is known to all of us.宾语从句：We all know (that） he is right.1. It 作形式主语和it引导强调句的比较It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。
而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that.被强调部分指人时也可用who/whom。
句子结构 02 宾语从句和定语从句
二、复合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。
主句和从句都具有完整的主谓结构，主句是全句的主体，从句是主句中的一部分，不能独立存在。
根据从句在全句中的不同作用，从句可分为：宾语从句、定语从句、状语从句、主语从句、表语从句和同位语从句。
在这里重点讲解宾语从句、状语从句和定语从句。
（一）宾语从句1.宾语从句的引导词注意：Whether和if引导宾语从句时，一般情况下可以互换，但在下列情况下须用whether，不能用if。
①具有选择意义，宾语从句中有or或or not时。
例如：We really don’t know whether the news is true or not.我们真的不知道这消息是否是真的。
②在介词后接宾语从句或不定式时。
例如：We are talking about whether we’ll go back to our hometown.我们正在讨论是否回老家去。
③作discuss等词的宾语时。
例如：We discussed whether we should close the shop.我们讨论了是否应该把商店关掉。
2.宾语从句的语序宾语从句无论是陈述句、一般疑问句或特殊疑问句意义，一律用陈述句语序，即“主语+谓语”结构。
句尾标点符号取决于主句。
例如：Are you a student？He asks.→He asks if you are a student.他问你是否是学生。
Where does he work？Do you know？→Do you know where he works？你知道他在哪工作吗？3.宾语从句的时态宾语从句的时态原则上应与主句的时态一致。
具体情况如下表：【典型例题】（2009·陕西）—Can you tell me your parents at home?—I often wash clothes and sweep the floor.A. how will you helpB. how you helpC. how you will helpD. how do you help【解析】本题考查宾语从句。
定语从句用法(含例句及解析)
1.定义:在复合句中修饰某一名词或代词的从句，叫定语从句。
它所修饰的名词或代词叫先行词。
2.构成:先行词+关系词+定语从句关系词作用:连接主句和从句; 指代先行词; 在从句中充当句子成分。
3.分类:限制性定语从句、非限制性定语从句。
4.关系词关系代词: that, which, who, whom, whose, as关系副词: when, where, why关系代词的具体用法见下表 :关系代词that which who 先行词人、物物人在从句中所做的成分主语、宾语、表语主语、宾语主语、宾语whom 人宾语whose 人、物定语as 人、物主语、宾语、表语指人也可指物, 在定语从句中可作主语、宾语或表语，作宾语时可省略。

我认识那个人，他的房子在地震中被彻底摧毁了。
(作定语)①关系代词指代先行词在定语从句中充当主语、宾语、表语或定语，因此定语从句中不能再出现关系代词所替代的名词或代词。
昨天晚上我们看的那部电影非常吓人。
The film (that/ which) we saw it last night was very frightening.(×)The film (that /which) we saw last night was very frightening.( √)②关系代词在从句中作主语时不能省略，作宾语时可以省略。

揭秘名词性从句
“揭秘”名词性从句名词性从句是高中英语考查的重点，也是高一年级的同学们学习的难点。
现在我将该语法中的难点一一为你“揭秘”，为你扫清学习名词性从句路上的“拦路虎”。
名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
一、主语从句和表语从句：作主语的从句就是主语从句，做表语的从句叫表语从句。
如：What she lacks is experience.中what she lacks就是由what引导的主语从句；The problem is why he refused my suggestion. 中why he refused my suggestion就是表语从句。
考查主语和表语从句时重点考查它们的引导词。
请同学们看看如下有关此类从句的练习与分析：1.See the flag on top of the building . That was ___ we did this morning .A when B. which C. where D. what【答案解析】D。
表语从句中缺did的宾语。
2. ________ knowledge comes from practice is known to all.A.WhatB.WhereC.IfD.That【答案解析】D.主语从句中不缺少任何成分，用that引导。
二、同位语从句有很多名词后可以跟that引起的从句，说明其内容，称作同位语从句。
请同学们看下面一个小题。
如：Nobody would stand out admitting the fact they lost the game.A. thatB. whichC. whatD. why【答案解析】A “they lost the game.”在句子中做the fact 的同位语从句, 对the fact的内容进行解释。
【注意】that引导的同位语从句和that引导的定语从句的差别：同位语从句时对其修饰的名词进行解释和说明，that在从句中不做任何成分；定语从句中的that必须代替先行词在从句中做主语或宾语。
【英语】状语从句综合分类解析
【英语】状语从句综合分类解析一、初中英语状语从句1．—The novel seems a little boring.—You won’t enjoy it _______________ you put your heart into it.A．when B．if C．after D．unless【答案】D【解析】试题分析：句意：--这部小说似乎有点儿无聊。
--如果你不用心读的话，你不会享受到这本书。
when，当……的时候；if如果；after在……之后；unless，如果不，除非。
结合句意，故选D。
考点：考查连词的用法。
2．_______riding shared bikes is an easy way to travel, it also causes some problems. A．Although B．If C．Until【答案】A【解析】【详解】句意：虽然骑共享单车是一种简单的旅行方式，但也会引起一些问题。
A. Although尽管，虽然；B. If如果；C. Until直到。
根据下文it also causes some problems.可知上文是Although 引导的让步状语从句。
根据题意，故选A。
3．He has made great progress his mother is very pleased with him.A．so；that B．enough；to C．so；too D．such；that【答案】D【解析】【详解】句意：他已经取得了如此大的进步以至于他的妈妈对他非常满意。
从句意可知这里需要用到“如此….以至于”so+形容词/副词+that或such+名词+that，根据句子中的great progress意思是很大的进步，是名词短语，故用such…that, 故选D。
4．___________ she couldn’t see his face, she could tell by his voice that he was young. A．Unless B．If C．Because D．Though【答案】D【解析】【详解】句意：虽然她看不见他的脸，但是她能够通过声音分辨出他很年轻。

从句是相对于主句而言的，即它是从属于某一个主句，而不能单独作一个句子。
在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。
主语从句用作主语，如：：
That the earth is round is true. 地球为圆的是真实的。
宾语从句用作宾语。
如：
Do you know where he lives?
表语从句用作表语，如：
My opinion is that you should not go alone. 我的意见是你不应单独前往。
同位语从句用于解释说明前面的名词。
如：
The fact that the earth is round is true. 地球是圆的的事实是真实的。
（that从句用于解释说明the fact）
定语从句相当于一个形容词，用于修饰前面的名词。
如：
The student who answered the question was John. 回答问题的学生是John.
状语从句相当于一个副词，如：
When it rains, I usually go to school by bus. 天下雨时，我通常坐公共汽车上学。
（时间状语）
If he comes tomorrow, you will see him. 如果他明天来，你就可以看见他。
（if 引导的条件状语从句，其结构为：if +状语从句，＋主句）。
要注意在状语从句中有一个规则是“主将从现”，即主句是将来时，则从句要用一般现在时表示将来。
He returned home to learn his daughter had just been engaged.他回家后得知女儿刚刚订婚了。
（结果状语，结果状语只是仅限于learn（得知），find（发现），see，hear，to be told （被告知），make（使得）等具有界限含义的动词。
）
You must speak louder so that /in order that you can be heard by all. 你必须大声说话，才能让所有人听到你说话。
（目的状语，可以由that, so that, in order that, lest, for fear that, in case等词引导。
）
Since /As the weather is so bad, we have to delay our journey. 天气那么糟，旅行推迟了。
（原因状语从句，常用because, since, as, for fear ( 恐怕), seeing that ( 既然) ，now that (=since), considering that ( 考虑到) 等引导。
）
Though/Though he was worn out, (still) he kept on working. 虽然他已经精疲力竭了，但仍然继续工作。
（让步状语从句，引导的连词主要有以下这些：though, although, as; even if, even though; whether...or...; no matter+疑问词，疑问词-ever.)
Where I live there are plenty of trees. 我住的地方树很多。
（地点状语从句，通常由where, wherever 引导。
）
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。
（方式状语从句通常由as, (just) as…so…, as if, as though引导。
）
主句和从句的划分方法是相同的。
句子的成分从谓语动词处来划分比较容易。
谓语动词前面
的部分是主语，后面常接宾语，修饰谓语动词的是状语，修饰主语、宾语的是定语，若谓语是系动词，则系动词后的部分是表语。
如：
I am a teacher. 其中，I 是主语，am是谓语，a teacher 是表语。
He likes playing football very mucy. 其中，he是主语，likes是谓语，playing football是宾语，very much是状语。
