如何区分定语从句、宾语从句和状语从句
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.

定语从句与其易混淆句型的辨析
学法导航 定语从句与其易混淆句型的辨析 安丘一中高二英语组李建文 众所周知，定语从句是高中英语学习中的一个语法重点，老师、同学们都对此予以重点关注。由此造成了这样一种现象：做题时，一遇到从句就往定语从句上想，尤其容易把一些形式上与定语从句相似的句型（主要是同位语从句、强调句、地点和时间状语从句）也当作定语从句来理解，结果产生错误。因此，从某个方面来说，解答定语从句题的关键是弄清它和易混淆句型之间的区别。 一、定语从句与同位语从句 定语从句和同位语从句都置于被修饰的名词或代词之后，形式上非常相似，尤其是由that引导时，最难区分。实际上，两者的根本区别在于句法功能不同，与先行词的关系不同。 1. 句法功能不同 定语从句相当于一个形容词，用来修饰、描述或限制其前面的名词、代词（称为先行词）或整个句子；同位语从句则相当于一个名词，是先行词所述内容的展开，即说明先行词的具体内容。 定语从句的引导词that在从句中一定充当句子成分；而同位语从句中的引导词that（被称为连接代词）在从句中只起连接作用，不充当任何句子成分。 定语从句的引导词在从句中作宾语或状语时，可以省略或被其他词代替；而同位语从句的引导词则一般不能省略，也不能被代替。 例1The news （that / which） we picked up from his informal conversation is true.我们从他的闲谈中听到的那个消息是真实的。 例2The news that Mr Li will teach us English next semester is true. 李先生下学期将教我们英语这个消息是真实的。 点评：例1的中that从句是定语从句，其作用相当于一个形容词，用来限定the news，that在从句中作宾语，可省略。例2中的that从句是同位语从句，其作用相当于一个名词，本身就是the news的内容，that不能省略。 2. 与先行词关系不同 定语从句所修饰、限定的先行词可以是名词或代词，当that省略时，定语从句本身是一个不完整的句子。而同位语从句通常与一些本身有具体内容可展开的名词连用，对这些名词进行补充说明或解释。常见的此类名词有：answer， belief， doubt， decision，explanation， fact， hope， idea， information， message， news， order， possibility，problem， promise， question， reason， story， suggestion， thought， truth等。同位语从句本身是一个完整的句子，常用that连接而不是用which 引导，that本身不充当句子成分，表示疑问意义的名词（如doubt， question等）后也可用whether， who， what 等疑问词引导。 例3The fact (that / which) she told me yesterday is very important.她昨天告诉我的事实非常重要。 例4The fact that she hasn’t known the result of the examination is clear.她还不知道考试成绩这个事实是显而易见的。 点评：例3中that / which引导的是定语从句，修饰fact，用以限定说明是哪个fact，
初中英语语法状语从句大全
初中英语语法状语从句大全 1.时间状语从句 引导连词有when，while，till，not…until，since， after ,before ,as soon as The bus won’t start until everybody gets on. 公共汽车直到每人都上车为止，才开动。 When he knocked at the door I was cooking. 当他敲门时，我正在煮饭。 Last night before he came back home, his wife had already cooked dinner and waited for 2 hours. 昨天晚上在他回到家之前，他的妻子已经做好晚饭足足等了他两小时之久。 After I went to church, I went shopping. 2. 地点状语从句 地点状语从句通常由where, wherever 引导。 Where there is a will, there is a way. 哪里有志向，哪里就有出路。有志者事竟成。 Where there is a life, there is a hope. 哪里有生命，哪里就有希望。留得青山在，不怕没柴烧。 Wherever you go, whatever you do, I will be right here waiting for you. 不管你去哪里，不管你做什么，我都会在此守侯你。
3.原因状语从句 引导连词有because，as, since。 He didn′t see the film because he had seen it. 他没有看那部电影，因为他已经看过了。 They couldn’t get on the train，for it was too crowed. 比较：because, since, as和for 1) because语势，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。 I didn't go, because I was afraid. Since /As the weather is so bad, we have to delay our journey. 2) 由because引导的从句如果放在句末，且前面有逗号，则能 够用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。 He is absent today, because / for he is ill. He must be ill, for he is absent today.
初中英语——If引导的条件状语从句
初中英语――if引导的条件状语从句 在主从复合句中修饰主句中的动词、形容词、副词等的从句叫做状语从句，状语从句一般可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、比较状语从句和方式状语从句九种。 在句子中做条件状语的从句称为条件状语从句。可置于句首、句尾，有时还可置于主语和谓语之间。引导条件状语从句的连接词有：if ,unless,as/so long as等 1.if引导的条件状语从句 表示在某种条件下某事很可能发生。 If we pay much attention to the earth, we'll have a better world. 如果我们多关爱地球，就会拥有一个更美好的世界 If it rains tomorrow, what shall we do? 如果明天下雨，我们怎么办？ 注意：if还可以引导虚拟条件句，表示不可实现的条件，从句中多用一般过去时或过去完成时。 What would happen if there were no water ? 如果没有水会怎样？ 2.unless引导的条件状语从句 unless的意思是如果不，除非。可与if...not互换。 You will fail in English unless you work hard. 你英语考试会不及格的，除非你更加努力。 3.as /so long as引导的条件状语从句 as /so long as意思是“只要” So long as you're happy,i will be happy. 只要你高兴，我就高兴。 4.once引导的条件状语从句 once引导的条件状语从句，意为“一旦...，就”，从句可置于主句前或后 Once you begin,never stop. 一旦开始，就绝不要停止 Maths is easy to learn once you understand the rules. 一旦你理解了规则，数学就不难学了。 提示：在条件状语从句中，用一般现在时代替一般将来时，用一般过去时代替过去将来时。 If the weather is bad next week, we'll put off the climbing. 如果下周天气不好，我们将推迟爬山。 Father told me if i worked hard he would buy me a gift. 爸爸告诉我，如果我努力学习，他会给我买一份礼物。
地点状语与定语从句的区别
where引导的定语从句和地点状语从句的区别是什么？ 最简单的办法是看where是否有指代先行词 应到定语从句还是状语从句的区别主要可以从以下三点来看： 一、where引导定语从句时, where是关系副词, 在从句中作地点状语, 其前面有表示地点的先行词, where引导的从句修饰先行词。例如: The bookshop where I bought this book is not far from here. This is the house where I lived two years ago. We will start at the point where we left off. 二、where引导状语从句时, where是从属连词, where引导的从句修饰主句的谓语动词, where前面没有表示地点的先行词。例如: Wuhan lies where the Changjiang River and the Han Jiang River meet. Make a mark where you have any doubts or questions. I found my books where I had left them. 有时, where引导的地点状语从句兼有抽象条件含义, 可放在主句的前面, 而where引导的定语从句则不能。例如: Where there is a will, there is a way. 〔谚语〕有志者事竟成。 Where there is water, there is life. 有水的地方就有生命。 三、在有些情况下, where引导的定语从句可转换为where引导的地点状语从句。例如: A tall building was put up at the place where there used to be a desert. （＝A tall building was put up where there used to be a desert. ）在以前曾是沙漠的地方盖起了一幢高楼。 Bam boo grows best in places where it is warm and where it rains often. （＝Bamboo grows best where it is warm and where it rains often. ）温暖而多雨的地方最适合于竹子生长。

Eg2: If you can read as many English books as possible, your English will be improved. 2、用法 语法引导条件状语从句最常用的连词是if, 由if引导的条件状语从句表示在某种条件下某事很可能发生if引导的条件状语从句既可以将从句放前面也可以将从句放后面。除了if 之外，还有其他连词也可以引导条件状语从句。 【注：在条件状语从句中，绝大数情况下some要变为any。】 (1) unless conj.除非，若不，除非在……的时候 Eg1: You will fail to arrive there in time unless you start earlier.如果你不早点动身，你就不能那儿。 Eg2: Unless it rains, the game will be played.除非下雨，比赛将照常进行。 (2) on condition(that)...在……条件下，如果on condition (that)...引导的是主句事件发生的前提条件或唯一条件。 Eg1: I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相，条件是你答应保密。 Eg2: You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 Attention（注意）： ①unless = if...not.

定语从句与强调句和状语从句的区别
定语从句与其易混淆句型的辨析 众所周知，定语从句是高中英语学习中的一个语法重点，老师、同学们都对此予以重点关注。由此造成了这样一种现象：做题时，一遇到从句就往定语从句上想，尤其容易把一些形式上与定语从句相似的句型（主要是同位语从句、强调句、地点和时间状语从句）也当作定语从句来理解，结果产生错误。因此，从某个方面来说，解答定语从句题的关键是弄清它和易混淆句型之间的区别。 一、定语从句与同位语从句 定语从句和同位语从句都置于被修饰的名词或代词之后，形式上非常相似，尤其是由that引导时，最难区分。实际上，两者的根本区别在于句法功能不同，与先行词的关系不同。 1. 句法功能不同 定语从句相当于一个形容词，用来修饰、描述或限制其前面的名词、代词（称为先行词）或整个句子；同位语从句则相当于一个名词，是先行词所述内容的展开，即说明先行词的具体内容。 定语从句的引导词that在从句中一定充当句子成分；而同位语从句中的引导词that（被称为连接代词）在从句中只起连接作用，不充当任何句子成分。 定语从句的引导词在从句中作宾语或状语时，可以省略或被其他词代替；而同位语从句的引导词则一般不能省略，也不能被代替。 例1The news （that / which）we picked up from his informal conversation is true.我们从他的闲谈中听到的那个消息是真实的。 例2The news that Mr Li will teach us English next semester is true. 李先生下学期将教我们英语这个消息是真实的。 点评：例1的中that从句是定语从句，其作用相当于一个形容词，用来限定the news，that在从句中作宾语，可省略。例2中的that从句是同位语从句，其作用相当于一个名词，本身就是the news的内容，that不能省略。 2. 与先行词关系不同 定语从句所修饰、限定的先行词可以是名词或代词，当that省略时，定语从句本身是一个不完整的句子。而同位语从句通常与一些本身有具体内容可展开的名词连用，对这些名词进行补充说明或解释。常见的此类名词有：answer，belief，doubt，decision，explanation，fact，hope，idea，information，message，news，order，possibility，problem，promise，question，reason，story，suggestion，thought，truth等。同位语从句本身是一个完整的句子，常用that连接而不是用which 引导，that本身不充当句子成分，表示疑问意义的名词（如doubt，question等）后也可用whether，who，what等疑问词引导。 例3The fact (that / which) she told me yesterday is very important.她昨天告诉我的事实非常重要。 例4The fact that she hasn’t known the result of the examination is clear.她还不知道考试成绩这个事实是显而易见的。

(完整word版)初中条件状语从句(附答案)
条件状语从句讲解及练习 一、考点归纳 由连接词if或unless引导的状语从句叫做条件状语从句。（注意：在含有条件状语从句的复合句中，如果主句是一般将来时态，从句要用一般现在是“主将从现原则”。通常译作“假如，如果，除非”。引导词： 常用引导词： if , unless 1.if 引导词用法 学习" if " 引导的条件状语从句的用法,现在总结一下: if 条件句不一般, 几个要点记心间; 条件句,放在前, 逗号要放句中间。 条件句表可能，主句多用将来时； 条件句表事实，主句常用现在时。 if 引导的条件句有：真实条件句和非真实条件句两种: （1）真实条件句：表示在某种条件下某事很可能发生。Eg: a)If you ask him, he will help you. 如果你请他帮忙,他会帮你的。 b)If you fail in the exam, you will let him down. 如果你考试不及格,你会让他失望 的。 c)If it rains tomorrow, we won’t go on a picnic. 如果明天下雨，我们就不去野餐。 注意：切记紧跟着if的那句话是从句。 （2）非真实条件句是虚拟语气的一种，表示与事实相反，不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。 Eg: a)If I were you, I would invite him to the party. 如果我是你,我会邀请他参加聚会。 b)I would have arrived much earlier if I had not been caught in the traffic. 如果没有堵 车,我会到的早一点儿。 c)If I were you, I would go with him. 如果我是你,我会和他一起去的。 2. unless引导词用法 （1）固定搭配： unless = if...not 除非,若不,除非在……的时候。Eg: a)You will fail to arrive there in time unless you start earlier. =If you don’t start earlier, you will fail to arrive there in time. 如果你不早点动身,你就 不能及时赶到那儿。 b)Unless it rains, the game will be played. =If it dosen't rain，the game will be played. 除非下雨,比赛将照常进行。 c)Let's go out for a walk unless you are too tired. d)= If you are not too tired, let's go out for a walk 经典语句：If it dosen't rain tomorrow,we will go to the zoo. 条件状语从句就是用以表示“在某
When引导的定语从句与时间状语从句的区分
一、从句是如何出题的 1. 时态 2. 考连接词 3. 考语言顺序 二、学好从句的两个基本条件 1. 时态 2. 从句的三个必须:①必须是句子；②必须有连接词；③必须是陈述句 三、状语从句、宾语从句、定语从句重点 1.如何判断何种从句 2. 从句的时态 3. 从句的连接词与扩展 4. 经典单选、从句与选词、长句子分析 四、如何判断三种从句 1. 状语从句无先行词 2. 宾语(表语)从句无先行词有动词或词组 3. 定语从句先行词多为名词或代词 一、When引导的定语从句与时间状语从句的区分 1. when的译法不同。在时间状语中，when 翻译成“当……的时候”I want to be a teacher when I grow up. 当我长大的时候，我要做一名老师。在定语从句中，when不翻译。I won't forget the day when he says he loves me. 我不会忘记他说爱我的那一天。 2. 在时间状语中，when从句前面或后面是句子；定语从句中，when从句不能位于句首，且通常when前为表示时间的名词day、year等。 3. when在从句的作用不同。在时间状语从句中，when是连词，只起连接主句和从句的作用，不做从句的任何成分。不过when引导的时间状语从句修饰主句的谓语，做主句的时间状语。 在定语从句中，when是关系副词，在从句中代替先行词做从句的时间状语，修饰从句的谓语。 例1 I will always remember the days when I lived with my grandparents in the country. 例2 I always remember the days in the country when I see the photo of my grandparents. 点评：例1意为“我会永远记得跟我祖父母一起住在乡下的那些日子”，其中when 引导的是一个定语从句, 修饰the days, when在从句中作时间状语。例2意为“当我看到祖父母的照片时，总是会想起在
初中英语语法状语从句-精华版
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. After he finished middle school, he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： I’ll ring you up as soon as I get to New York. I will tell him everything when he comes back. He won’t believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里 如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。 如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。 例如： The young man read till the light went out（熄灭）. Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off（从下来）until the bus stops. 【。固定组合里from morning till night，till/until是不能替换的，】 2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow? Don’t leave the building unless I tell you to. (2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： I’ll help you with your English if am free tomorrow. He won’t be late unless he is ill. (3)“祈使句+ and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。例如： Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如： He didn’t come to school because he was ill. As it is raining, we shall not （不得；不应该）go the zoo. Since you can’t answer the question, I’ll ask someone else.
