三大类从句
初中英语语法三大从句汇总
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、定语从句概念定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。
定语一般是由形容词充当，所以定语从句又称作形容词从句。
另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。
定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。
请看示例：The woman who lives next door is a teacher. (先行词)二、关系代词引导的定语从句关系代词代替前面的先行词，并且在定语从句中充当句子成分，可以作主语、宾语、定语等。
常见的关系代词有：who, that, which。
它们的主格、宾格和所有格如下表所示：（一）关系代词who, whom和whose的用法who代替人，是主格，在定语从句中作主语。
例如：An architect is a person who designs buildings. 建筑师是设计房屋的人。
whose一般代替人，有时亦可代替物，是所有格，在定语从句作定语。
例如：The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在国外留学。
（二）关系代词which的用法which代替物，在定语从句作主语或宾语，作宾语时还可省略。
例如：I do not like stories which have unhappy endings.我不喜欢有不幸结局的小说。
（which可以换成that）（三）关系代词that的用法that既可指人又可指物，在当代英语中大多指物，在定语从句作主语或宾语，作宾语时还可省略。
三大从句语法
从句可分为三类:即名词性从句、形容词性从句(即定语从句)与副词性从(即状语从句)。
引导从句得词称作关联句、一、名词性从句引导这些名词性从句得关联词包括: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,而连接代词与连接副词既起连接作用, 在从句中又充当一定得成分、不可省略得连词:1、介词后得连词2、引导主语从句与同位语从句得连词不可省略。
Thａt sｈe wａsｃｈｏsen made uｓverｙhappy。
We ｈearｄtｈe news tｈat our teaｍｈａd won。
比较:whethｅr与ｉf 均为”就是否”得意思、但在下列情况下,ｗhetｈer 不能被iｆ取代:1、ｗhetheｒ引导主语从句并在句首２、引导表语从句３、wheｔheｒ从句作介词宾语4、从句后有”ｏr not"例:Whｅther he will coｍe iｓnot cleaｒ、The fａct iｓｔhaｔhe didn＇t ｇｏto ｔhｅdinnｅr pａrty。
I don't kｎow if hｅwill atｔend tｈe meｅtｉｎｇ、1。
在含有主语从句得复合句中, 为保持句子平衡, 常用ｉt作形式主语,而将真正得主语从句置于句末、That—从句作主语通常用ｉt作先行词,而将thaｔ-从句置于句末,例如:It is ｑｕｉteｃｌｅar ｔhat thｅwhｏｌe project ｉs doomeｄｔo faｉｌｕrｅ、很清楚,整个计划注定要失败、It'sａｐiｔy thaｔyouｓhoulｄｈaveｔoｌeavｅ.您非走不可真就是件憾事。
英语中三大类从句
从句概述
• 从句只能做主句的某一部分,依附于主句 而存在,不能独立。
• 从句也具有句子的特征，即有自己的主 谓结构；而且带有引导词。
• 根据从句在句中的作用，可分为名词性 从句、形容词性（定语）从句和副词性 （状语）从句三类。
一、名词性从句
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。其关 联词有连词that, if, whether；连接代词what, who, which和连接副 词when, where, why, how等。
Ryan was worrying about whether he had hurt her feelings. ⑶ or not紧随其后时；I don’t care whether or not he has a holiday. ⑷ 后接不定式时。 She can’t decide whether to go.
连接词的用法 (三)
３．Who, whom, whose, what, which
连接代词Who, whom, whose, what, which等 在从句中既起连接作用，又担当主语、宾语、表 语等成分，并保留其特殊疑问词词义。如：
No one knows who he was waiting for. Tell me whose house it is. Let me know which train you will be arriving on.
④ It +v. (seems / happened, etc. )+that-clause It seems that Alice is not coming to the party at all. It happened that I was out that day.

从句可分为三类:即名词性从句、形容词性从句（即定语从句）和副词性从(即状语从句）。
引导从句的词称作关联句。

高中英语三大从句
高中英语主要要掌握三大从句。
分别是：1、定语从句（形容词从句）2、名词词从句（包括主语从句，宾语从句，表语从句，同位语从句）3、状语从句（副词性从句，包括时间，地点，结果，目的，原因等）一、定语从句：定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词。
定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
1、关系代词引导的定语从句关系代词所代替的先行词是人或物的名词或代词，并在从句中充当主语、宾语、定语等成分。
关系代词在定语从句中作主词保持一致。
（1）, who, whom, that既可作主语又可作宾语（作宾这些词代替指人，“whom”作宾语指人，“that”语可以省略），可以指人也可以指物。
（2），Which 用来指人或物(用作主语、宾语，作宾语时可以省略）（3），whose“whose”表示谁（可以为人也可以为物）的（东西）2、关系代词引导的定语从句（1），关系副词why主要用于修饰表示原因的名词（主要是the reason），同时它在定语从句中用作原因状语。
（2），关系副词when主要用于修饰表示时间的名词，同时它在定语从句中用作时间状语。
（3），关系副词where主要用于修饰表示地点的名词，同时它在定语从句中用作地点状语。
3、非限制性定语从句它起补充说明作用，缺少也不会影响全句的理解。
在非限制性定语从句的前面往往有逗号隔开。
二、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，名词性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。
引导名词性从句的连接词可分为三类：1、连词（5个）：that （宾语从句或表语从句中that有时可以省略）whether,if （均表示“是否”表明从句内容的不确定性）as if ,as though （均表示“好像”，“似乎”）以上在从句中均不充当任何成分2、连接代词（9个）：what, whatever, who, whoever, whom, whomever, whose, which, whichever3、连接副词（7个）：when, where, how, why, whenever, wherever, however三、状语从句状语从句（Adverbial Clause）状语从句指句子用作状语时，起副词作用的句子。
