英语八大从句类型总结用法有哪些
从句是复句中具有分属地位的分句，它是一种绝大部分语言都有的语法结构。在现代汉语的语法中，“从句”不作为专业术语被使用。
1 英语从句可以分哪几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（connective）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）

高中英语的定语从句归纳与总结
定语从句 概念：定语从句，一个简单句跟在一个名词或代词后（先行词）进行修饰限定，就叫做定语从句。在主句中充当定语成分。被修饰的词叫先行词。定语从句不同于单词作定语的情况，它通常只能放在被修饰的词（即先行词）之后。定语从句由关系词（关系代词、关系副词）引导，关系代词、关系副词位于定语从句句首。 结构：先行词+关系词+从句 关系词： 关系词的类型：关系代词：who,whom,which,that,在从句中可作主语或宾语，whose,在从句中作定语 关系副词：why,where,when,其中why=for which，where=in/at/on which， when=during/on/in which,在从句中做状语 关系词的作用：1.连接作用，连接主句和定语从句 2.指代前面的先行词 3.在定语从句中担任成分 关系词的选择:1.看先行词（被定语从句修饰的词）先行词是“物”可能用which，that，whose,where，when，why等,先行词是“人”可能用who，whom，that， whose等 2.看关系词在定语从句中所担任的句子成分①先行词是人且关系词在从句 中作主语，用who/that②先行词是人且关系词在从句中作宾语，用 whom/that③先行词是物且关系词在定语从句中作主语，用that,which. ④先行词是物且关系词在从句中作宾语，用that,which，也可以省略 记住：关系代词作宾语或表语是可以省略的，作主语是不能省略的，因为主 语后直接是动词，省略的话就出现先行词直接接从句动词的语法错误。举例： Is there anything that you want to say? 中的that就可以省略。而He is the headmaster of this school who also teaches Chemistry. 中的who就不能省 略。⑤先行词是“人”或“物”，关系词在从句中作定语表所属关系，用 whose引导定语从句.注意：表示所属关系不仅仅是人,这个就叫做所属关系， 因此所属关系除了whose以外就有两个，对人是of whom,对物是of which. ⑥先行词是时间、地点或理由的名词，则用关系副词引导定语从句。注意： 如果从句中的谓语动词是及物动词且后面无宾语，那么，即使先行词是表时 间、地点或理由的名词，也不能用关系副词（when，why，where），而要用 可作宾语的关系代词that或which，要考试的同学们千万千万要记住哦！ 3.必须用that引导的情况①先行词是不定代词all, few, little, much, something, nothing, anything等②先行词被序数词或形容词最高级所修饰③先行词被 all, any, every, each, few, little, no, some等修饰④先行词被the only, the very, the same, the last修饰时⑤先行词既有人又有物时⑥当句中已有who时， 为避免重复用that 限定与非限定定语从句 定语从句可分为限定性定语从句和非限定性定语从句 限定性定语从句： 例：I like the book which he bought yesterday.(我喜欢他昨天买的书) 非限定性定语从句：

英语六大从句用法总结
英语中六大从句用法总结 从句是指用于复合句中担当某个句子成分的主谓结构。虽说从句自身的句子结构是完整的，但是它不能视为独立的句子，因为它离开了主语就无法独立、完整地表达意思。按其所能表达的意义而言,它相当于一个词或是一个词组. 按从句的句子功能划分（也就是按从句在句子中所担任的成分来划分），从句可分为：主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句。 1.主语从句 1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有： *It is a fact\a pity\a question\good news that... *It seems\appears\happened\has turned out that... *It is clear\important\likely\possible that... *It is said\reported\estimated\has been proved that... It is said that comic books create a connection between people of the same generation. It seems that the performance is very useful. 2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。 What we lack is experience. 3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。 How the plan is to be carried out should be discussed again. I did know why I felt like crying. 2.宾语从句 1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。 *I promised that I would change the situation. *All this is different from what American young people would say about friendship. *He is certain that watching so much television is not good for children. *This article is well-written except that it is a bit too long. 2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。 He has made it clear that he would not change his mind. 3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。 He didn't think that the money was well spent. 3.表语从句 表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because.
