从句的用法归纳总结
从句的用法归纳总结从句是英语语法中重要的一部分，它是指用一个句子来作为另一个句子的一个部分。
从句可以用来表达更复杂的意思，也可以用来让句子更加简洁。
下面将从六个方面来归纳总结从句的用法。
1. 从句类型从句可以分为三大类：名词性从句、形容词性从句和副词性从句。
名词性从句是指用一个句子来作为名词，例如：I think that he will come.（我认为他会来。
）其中that he will come就是一个名词性从句。
形容词性从句是指用一个句子来作为形容词，用来描述主语或宾语的特点，例如：He is a student that always studies hard.（他是一个总是努力学习的好学生。
）其中that always studies hard就是一个形容词性从句。
副词性从句是指用一个句子来作为副词，用来描述主句中的动词或形容词的情况，例如：When he comes, we will go to the party.（当他来的时候，我们会去参加聚会。
）其中When he comes就是一个副词性从句。
2. 从句引导词从句的引导词有很多种，不同的引导词可以引导不同类型的从句。
常用的引导词有：* that：可以引导名词性从句和形容词性从句，但是不能引导副词性从句；* what：可以引导名词性从句；* who：可以引导名词性从句和副词性从句；* whom：可以引导名词性从句；* which：可以引导名词性从句；* where：可以引导副词性从句；* when：可以引导副词性从句；* why：可以引导名词性从句；* how：可以引导名词性从句和副词性从句。
3. 从句语序在英语中，主句和从句的语序一般是不同的。
主句通常采用陈述语序，而从句则可以采用疑问语序或倒装语序。
例如：Do you know where he lives？（你知道他住在哪里吗？）其中where he lives就是一个名词性从句，采用了疑问语序。
从句归纳总结
从句归纳总结在英语语法中，从句是一种包含一个主语和一个谓语的句子，可以用作复合句的一部分。
从句可以分为主从句和名从句两种类型。
主从句是指在复合句中充当主句或从句的一部分，而名从句是指充当名词的一部分。
本文将对主从句和名从句进行归纳总结。
一、主从句主从句是复合句的一种常见结构，由一个主句和一个或多个从句组成。
主从句之间有明确的层次关系，从句在语法上依赖于主句。
下面是一些常见的主从句类型：1. 定语从句：用来修饰名词或代词的从句，通常由关系代词（如who, whom, whose, which, that）引导。
例如：The book that I bought yesterday is very interesting.（我昨天买的那本书很有趣。
）The person who is standing over there is my brother.（站在那边的人是我的哥哥。
）2. 名词从句：用来充当名词的从句，通常由连接词（如that, whether, if, who, what）引导。

）She asked me if I could help her.（她问我是否能帮她。
）3. 时间从句：用来表示时间的从句，通常由引导词（如when, while, before, after）引导。

）She was reading a book while she waited for the bus.（她在等公共汽车时看书。
）4. 原因从句：用来表示原因的从句，通常由引导词（如because, since, as, for）引导。

状语从句还可以分为条件状语从句、原因状语从句、方位状语从句和时间状语从句。

3.宾语从句（Object Clause）：在句子中起宾语作用的从句叫做宾语从句.宾语从句分为动词的宾语从句,介词的宾语从句和形容词的宾语从句。
一、主语从句★定义：主语从句时名词性从句中的一种，指句中的主语是一个完整的句子。

英语的从句类型与用法总结
英语的从句类型与用法总结
英语的从句类型与用法总结如下：
1.定语从句：在复合句中，修饰名词或代词的从句叫定语从句，被修饰的名词或代词叫先行词，引导定语从句的有关系代词（who, whom, whose, which, that 等）和关系副词（where, when, why等），关系代词和关系副词在定语从句中担任句子成分。

无论是哪种从句类型，在句子中充当成分的"句子"应该都具备以下特征：从句=从属连词+句子了解了从句的基本结构，那么应该如何辨别从句类型呢?1学生可以在句子中通过简单的公式进行辨认。
常见的从句出现形式有四类：1. 名词+从属连词+句子=定语从句/同位语从句2. 动词+从属连词+句子=宾语从句/表语从句3. ×+从属连词+句子=状语从句4. 从属连词+句子+动词=主语从句三、辨认方法和注意事项1. 名词+从属连词+句子=定语从句/同位语从句例子1：Yet, being friendly is a virtue that many Americans value highly and expect from both neighbors and strangers.(1997年Text2)从句类型：定语从句辨别方式：a virtue(名词)+that(从属连词)+many Americans value highly and expect from both neighbors and strangers(句子)译文：然而，表示友好是一种美德，美国人高度重视这种美德，并期望邻居和陌生人都能有这种美德。

meet again.他没有告诉我什么时候我们能再见面.三、动词的宾语从句大多数动词都可以带宾语从句We all expect that they will win , for members of their team are stronger.我们都预料他们会赢,因为他们的队员更强壮.★部分“动词+副词”结构也可以带宾语从句例句：I have found out that all the tickets for the concert have been sold out.我发现这场音乐会的所有票都卖光了.★动词短语也可以带宾语从句常见的这些词有：make sure确保make up one’s mind下决心keep in mind牢记例句：Make sure that there are no mistakes in your papers before you turn them in.在上交试卷前确保没有任何错误.四、可运用形式宾语it代替的宾语从句①动词find,feel,consider,make,believe等后面有宾语补足语的时候,则需要用it做形式宾语而将that宾语从句后置.例句：I think it necessary that we take plenty of hot water every day .我认为每天多喝开水是有必要的.②有些动词带宾语从句时寻要在宾语与从句前加it这类动词主要有:hate, take , owe, have, see to.例句：I hate it when they with their mouths full of food.我讨厌他们满嘴食物时说话.③若宾语从句是wh-类,则不可用it代替例句：We all consider what you said to be unbelievable.我们都认为你所说的是不可信的.五、介词的宾语从句用wh-类的介词宾语从句例句：We are talking about whether we admit students into our club.我们正在讨论是否让学生加入我们的俱乐部.★用that,if引导的介词宾语从句有时候except,but,besides三个介词后可见到that引导的宾语从句例句：I know nothing about my new neighbor except that he used to work with a company.对于我的新邻居我只知道他曾在一家公司上班,其他一无所知.六、形容词的宾语从句常用来引导宾语从句的形容词有:sure,certain,glad,please,happy,sorry,afraid,satisfied,surprised例句：I am sure I will pass the exam.我确信我会通过考试.七、if,whether在宾语从句中的区别①if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if②少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.③whether后可以加or not,但是if不可以.④在不定式前只能用whether.如：I can’t decide whether to stay. 我不能决定是否留下.⑤避免歧异时,我们常用whether而不用if.八、哪些宾语从句不可以省略引导词that1.当that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语时;2.当宾语从句较长时;3.当主语状语置于主句尾,宾语从句之前时;4.当主语谓语动词(包括非谓语动词)与宾语从句之间有插入语时;5.当一个动词带有两个或两个以上宾语从句时,此时第一个that可以省略,第二个that不可以省略;6.当宾语从句中的主语是this,that或this,that做主语的定语时;7.当宾语从句是双宾语中的直接宾语时;8.当宾语从句的主语是非谓语动词或主语从句时;9.当主语中的谓语动词是固定词组时;10.当宾语从句有it做其先行词时;11.在直接引语中,转述分句把宾语从句隔开时.九、宾语从句的否定转移主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致.例句：I

he?我们发现他从来不仔细听老师讲课,是不是?十、宾语从句的时态和语序当主句为现在时或将来时的时候,宾语从句的时态一般不受主句的时态所影响.当主句为过去时的时,细分为一下几种情况：①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生例句：I only knew he was studying in a western country,but I didn’t know what country he was in.我只知道他当时在西方的一个国家读书,可不知道是哪个国家.②从句过去完成时表示该动作发生在主句谓语动作之前例句：He told me that he had told Mary about the meeting already.他告诉我他已经把有关会议的事情告诉的了Mary.③从句谓语用过去将来时表示该动作发生在主句谓语动作之后例句：The reporter asked if the government would take necessary measures to put down the to-do.记者问政府是否会采取必要的措施镇压骚乱.★如果从句是一个客观真理,那么从句的时候不根据主句的时态而变化例句：The teacher said that the moon goes around the earth yesterday.老师昨天说月亮绕着地球转.★当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时,不能按正常语序安排,经常将这类引导词置于句首例句：Who do you think the public might choose as their favorite singer this year?你认为今年公众会选谁为他们最喜欢的歌手.同位语从句用法比较"固定",把关键的几个词背下来 下面这个材料供参考）：一、在复合句中用作同位语的从句叫同位语从句.它一般跟在某些名词后面,用以说明该名词表示的具体内容.如：I had no idea that you were here．我不知道你在这里.二、可以跟同位语从句的名词通常有news,idea,fact,promise,question,doubt,thought,hope,message,suggestion,words消息）,possibility等.如：I’ve come from Mr wang with a message that he won’t be able to see you this afternoon．我从王先生那里来,他让我告诉你他今天下午不能来看你了.三、英语中引导同位语从句的词通有连词that,whether,连接副词how,when,where等.（ 注：if,which 不能引导同位语从句.）如：l have no idea When he will be back．我不知道他什么时候回来.四、有时同位语从句可以不紧跟在说明的名词后面,而被别的词隔开. 如：The thought came to him that maybe the enemy had fled the city．他突然想起可能敌人已经逃出城了.五、同位语从句与定语从句的区别.1、同位语从句与前面的名词是同位关系,即说明它前面名词的内容；而定语从句与前面的名词是修饰与被修饰关系,即限定它前面的名词范围,或补充一些情况.如：The news that l have passed the exam is true．我通过了考试这一消息是真的.同位语从句,即从句所表达的意思就是前面名词的内容.）The news that he told me just now is true．他刚才告诉我的消息是真的.定语从句,从句对前面名词起修饰限制作用,即“他告诉我的”那个消息,而不是别的消息.）2、引导同位语从句的that是连词,在从句中不充当任何成份,而引导定语从句的that是关系代词,除起连接作用外,还在从句中充当主语、宾语或表语等.如：The idea that computers can recognize human voices surprises many people.计算机能够识别人的声音的想法使许多人感到惊奇.that在从句中不充当任何成份.）一个名词(或其它形式)对另一个名词或代词进行修饰,限定或说明,这个名词(或其它形式)就是同位语.同位语与被它限定的词的格要一致,并常常紧挨在一起.1) 非独立的同位语：常出现在被限定词前Bruce Lee (姓名) 李小龙Graf Schmidt (称号,浑名) 施密特伯爵Doktor Wang (职称,头衔) 王博士Uncel Liu (亲戚的称呼) 刘叔叔die Stadt Shanghai (类属名称) 上海市the Province Hebei (类属名称) 河北省das Jahr 2000 (类属名称) 2000 年three Kilo tomato (度量名称) 三公斤西红柿the University Bremen (专有名词) 不来梅大学。

英语的从句类型与用法总结资料
英语的从句类型与用法总结资料英语的从句类型与用法总结资料1英语从句分类介绍从句体系包括：从句体系(从句系统)图示从句体系(从句系统)图示第一，名词性从句(主语从句、表语从句、宾语从句及同位语从句)第二，定语从句第三，状语从句分类从句不能单独成句，但它也有主语部分和谓语部分，是一个特殊句子，就像一个句子一样。
所不同在于，从句须由一个关联词引导。
根据从句语法功能的不同可分为：主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。
前四类由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，所以通称名词性从句;定语从句功能相当于形容词，称为形容词性从句;而状语从句功能相当于副词，称为副词性从句。
状语从句还可以分为条件状语从句、原因状语从句、地点状语从句、目的状语从句、让步状语从句、比较状语从句、方式状语从句、结果状语从句和时间状语从句。
主语从句(Subject Clause)用作主语的从句叫主语从句。
引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。
表语从句(Predicative Clause)用作表语的从句叫做表语从句。
引导表语从句的关联词与引导主语从句的关联词很多都一样。
宾语从句(Object Clause)在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类：动词的宾语从句、介词的宾语从句和形容词的宾语从句。
同位语从句是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一，从句作同位语表示与之同位的名词(短语)的实际内容，它的作用相当于名词，对前面的名词(短语)加以补充说明或进一步解释，相当于一个表语从句，它们之间的关系就是同位关系，即主表关系。
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。
状语从句可分为：时间状语从句(adverbial clause of time)地点状语从句(adverbial clause of place)原因状语从句(adverbial clause of cause)条件状语从句(adverbial clause of condition)目的状语从句(adverbial clause of purpose)让步状语从句(adverbial clause of concession)比较状语从句(adverbial clause of comparison)方式状语从句(adverbial clause of manner)结果状语从句(adverbial clause of result)2英语八类状语从句的用法归纳一、概说状语从句即指在主从复合句用作状语的从句。
