从句归纳 区分定语从句、宾语从句、同位语从句
从句小结从句总述：从句有主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。
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，故而这4种从句又通称名词性从句。
1.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。
2.表语从句（Predicative Clause）：用作表语的从句叫表语从句。
引导表语从句的关联词与引导主语从句的关联词大都一样。
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.4. 同位语从句（Appositive Clause）：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。
其关联词多为that。
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等。
宾语从句学习宾语从句要抓住三要素：时态、语序、连接词。
一：时态和语序1·主句用一般现在时，从句可用任意时态。
2·主句用过去时，从句用过去某个时态。
3·主句用过去时，从句是真理时，只用一般现在时。
语序：宾语从句只能用陈述句语序，坚决不能用疑问句语序。
二：连接词①从属连词连接宾语从句的从属连词主要有that，if，whether. that引导表示陈述句的宾语从句,而if和whether引导表示“是否”的宾语从句.例句：He told that he would go to the college the next year他告诉我他下一年上大学.I don’t know if there will be a bus any more.我不知道是否还会有公交车.②连接代词连接代词主要有who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever等.连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述.例句：Do you know who has won Red Alert game你知道谁赢了这一局红警游戏吗③连接副词连接副词主要有when,where,why,how,whenever,wherever,however等.例句：He didn’t tell me when we should 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.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.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.I feel it a pity that I haven’t been to the get-together.我没去聚会,感觉非常遗憾.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.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.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：形容词的宾语从句一般来说形容词不能带宾语，更不能带宾语从句。
定语从句与易混淆句型
Let’s have a try at once
• She expressed the hope that they would come to visit China again.
同位语从句：they would come to visit China 对hope 进行具体的解释说明。
• The hope that she expressed is that they would come to visit China again.
4. (1) Is this school __D___ you ever visited? (2) Is this the school __A___ you ever studied? (3) Is this the school in __B___ you ever studied? A. where B. which C. that D. the one
定语从句与并列句的主要区别： 并列句有像and，but，so等并列连词 或两个句子用分号连接， 这时就不能再用引导定语从句的关系词了。
Practice:
① Mr. Smith made a lot of money，
most of ____ was spent helping the poor．
②It is the factory w__h_e_re_ Mr. Wang works．
强调句的结构为: “It is／was＋被强调部分＋that＋从句” 强调句检测的标准： 先把It is／was, that去掉，再把被强调部分还原， 在不增加或减少任何单词的情况下， 如句子仍然成立则为强调句，否则为定语从句。

英语句子成分主语谓语宾语表语定语状语补语同位语讲解[整理版]主语从句即一个句子作主语如:what he said is true. what he said是一个句子具备最短的句子所应有的主语(he)和谓语动词(said)。
又应有what引导词所以做从句，又Is 是大句子中的谓语动词，在主句中，所以其前的成分为主语，主语是一个句子，叫做主语从句。
宾语从句和主语从句同理，事不过宾语从句是在谓语动词后的句子，谓语后的成分是宾语。
如: He said that the girl is beautiful. that the girl is beautiful为宾语从句，做动词said后的宾语。
表语从句依然如此，只是动词为系动词或感官动词，动词后为表语从句。
如:He is who I am looking for. who I am looking for. 为表语从句，做系动词is的表语。
前几种句子均为名词性从句，引导词指人用who whose whom,指物用which，what。
其中which有范围 what没范围。
连接副词有:when where why how四种。
如:I don't know where he is going.(宾从)定语从句为形容词性从句，即一个句子像一个形容词，修饰一个名词或代词，而被修饰的词在句子前面，叫做先行词。
如:The girl who wears a red coat is my classmate. 其中who wears a red coat 是定语从句，修饰the girl, 所以the girl为先行词，主句为The girl is my classmate。
定语从句引导词指人和名词性从句相同，who whose whom;指物只用which，没有what;that 即指人又指物。
关系副词没有how 即 when,where,why.如: The year when I arrived there is 2000. (when I arrived there为从句)状语从句考点比较简单，记住他引导词的意思就行了，如时间是when while 等，地点是where wherever,原因是why 结果because等就可以了英语主谓宾表定状补成分精简讲解一(主语:主语(subject) 是一个句子的主题( theme)，是句子所述说的主体。
高中英语知识点归纳表语从句与同位语从句的区别
高中英语知识点归纳表语从句与同位语从句的区别高中英语知识点归纳——表语从句与同位语从句的区别表语从句和同位语从句是英语语法中相似但又有细微差别的两个概念。
在句子中，它们都可以作为主语、宾语或表语，但它们在句法结构和使用方法上有一些显著的区别。
本文将重点介绍表语从句和同位语从句的区别，帮助读者更好地理解并正确运用这两个知识点。
一、表语从句表语从句是一个从句，用来作为句子的表语。
它通常用来描述或说明主语的状态、性质、身份、职业等。
表语从句一般由连接词that引导，连接词that在口语中常被省略。
1. 结构及例句：表语从句的结构为：主语 + be动词/系动词 + that从句。
例如：- My dream is that I can travel around the world one day.（从句作主语）- The fact is that he didn't pass the exam.（从句作表语）2. 特点：- 表语从句中的谓语动词通常是be动词或系动词。
- 表语从句中的连接词一般为that，有时也可以用whether或其他连接词。
- 当主句的主语和表语从句的主语一致时，表语从句的主语可以省略，而只保留连接词和谓语。
二、同位语从句同位语从句是一个从句，用来解释或说明前面的名词或代词的含义、意义等。
同位语从句常常用来作为名词的同位语，起到进一步解释说明的作用。
1. 结构及例句：同位语从句的结构为：名词/代词 + 连接词 + 从句。
例如：- The fact that he didn't pass the exam disappointed his parents.（从句作同位语）- I have no idea who will be the winner.（从句作同位语）2. 特点：- 同位语从句中的连接词可以是that、whether、if等。
- 同位语从句同样可以出现在句子的各个位置，可以作为主语、宾语或表语。
高考英语复习难点：状语+定语+表语+主语+同位语+名词性+宾语从句
状语从句一、概说状语从句即指在主从复合句用作状语的从句。
按照其意义，状语从句可分为时时间状语从句、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、让步状语从句等。
状语从句是高中英语学习中的一个语法重点，也是历年高考重点考查的内容之一。
学习状语从句主要应注意引导状语从句的从属连词的用法与区别，以及从属连词在一定的语言环境中的意义与用法。
二、时间状语从句1. 引导时间状语从句的从属连词引导时间状语从句的从属连词很多，如较基本的有before, after, when, while, as, since, till, until, as soon as 等：Things were different when I was a child. 我小时候情况与现在不同。
We must strike while the iron is hot. 我们要趁热打铁。
It’s a long time since I met you last. 从上次见到你，已有很长时间了。
He waited until she was about to leave. 他等着一直到她准备离开。
除以上基本的引导时间状语从句的从属连词外，还有些本来不是从属连词却可用作从属连词的词：(1) 表示“一…就”的从属连词：the moment, the minute, the second, the instant, immediately, directly, instantly, once, no sooner…than, hardly…when等。
如：Immediately he came I told him the news. 他一来我就把消息告诉了他。
The moment I saw him I knew there was no hope. 我一看到他就知道没希望了。
We had no sooner set out than it began to rain. 我们刚出发就下雨了。
三种易混从句的辨别
三种易混从句的辨别专题策划：这样备考三类从句编者按：英语中有三类从句，即名词性从句、定语从句和状语从句。
这三类从句的学习、掌握和使用对同学们来说是一个颇为复杂的过程。
本专题通过对比分析这三大从句的区别，归纳三大从句与动词不定式的转换规律，希望能帮助同学们掌握区分从句与解答从句类考题的方法，并学会在书面表达中正确使用从句。
定语从句、同位语从句和状语从句有时候在形式上很相似，下面提供一些区分的方法。
一、定语从句与同位语从句定语从句与前面的名词是修饰与被修饰的关系，而同位语从句是用来说明前面名词的内容的。
that在定语从句中充当句子成分，可指物或人，而同位语从句中的that在从句中不充当任何句子成分，只起连接作用。
试比较：①The news（that/which）he told us was exciting.（定语从句，that/which在从句中作宾语，可以被省略）②The news that our team has won is exciting.（同位语从句，that从句是说明news的内容的，that在从句中不作任何成分，但不能省略）特别提醒：一般情况下，同位语从句紧跟在它所说明的名词之后，可是有时为了表达的需要，名词与从句之间被另外一些内容分隔开了，叫“分隔同位语从句”。
对于这类同位语从句，一定要根据句意，找准其所说明的名词。
例1 （2014年高考安徽卷）The exact year _____ Angela and her family spenttogether in China was 2008.A. whenB. whereC. whyD. which解析：本题中的定语从句的先行词是the exact year，后面的定语从句Angela and her family spent together in China中动词spent后面缺少宾语，所以使用关系代词which 引导这个定语从句，并在句中作宾语。

高中英语从句考点汇总,
高中英语从句考点汇总,建议收藏！语法是很多同学薄弱的地方，想要努力提分，却总是感觉有些力不从心？这几天小编将高中英语关于从句的内容全部整理了一遍，这部分内容也是考试中经常出现有容易出错的部分，大家赶紧收藏起来仔细学习，把不懂的语法内容都捋顺！一、主语从句在主句中用作主语的主谓结构称之为主语从句。
例句：That he will come to the discussion is certain. 他来参加讨论是确定的。
That the moon moves round the earth iswell known to all of us.月球绕地球转动，这是我们大家都熟知的。
When the meeting is to be heldhas not yet been decide.会议什么时候召开还没有决定。
主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。
例如上面的句子可以分别改写为：It is certain that he will come tothe discussion.It is well known to all of us thatthe moon moves round the earth.二、宾语从句在主句中作谓语动词、介词及非谓语动词的宾语的主谓结构称之为宾语从句。

1. 动词后的宾语从句We know that a parrot can’t really speak.我们知道鹦鹉不会真的说话。
He wants to tell us what he thinks.他想告诉我们他所想的事情。

Notice：
1、引导主语从句的that在从句中起到结构的作用，在句意中没有意义，但不可省略。 2、引导主语从句的whether不可用if替换。 3、单个主语从句的谓语用第三人称单数形式。
4、主语从句用陈述语序。
That education plays a vital role in all walks of life is clear.
Whether you can succeed in making your dream come true depends on hard work more than luck.
