高中阶段要求掌握和使用三种从句：1.名词性从句：主语从句，表语从句，宾语从句，同位语从句2.定语从句3.状语从句
高中阶段对从句的掌握要求：1.在语法填空（阅读填空）中能正确判断从句类型并填入连接词2.在书面表达中根据需要尽量使用含从句的复合句，避免全程使用简单句或简单的并列句
主语从句：在复合句中充当主语成分的句子
That he finished writing the cmpsitin in such a shrt time surprised us all.他在很短的时间内写完作文让我们都很惊讶。（主语从句位于主句的谓语动词之前）
同位语从句：在复合句中充当同位语成分的句子，对前面的抽象名词进行解释说明
宾语从句：在复合句中担任宾语成分的句子叫宾语从句
表语从句：在复合句中，担任表语成分的句子。

He tld that he wuld g t the cllege the next year.他告诉我他下一年上大学.（位于主句谓语动词动词、介词等词性后面）
主语从句常视作第三人称单数形式，主句谓语动词的单复数常据此判断。引导主语从句的从属连词有：that（不能省略）, whether(是否，不能用if替代)，连接代词：wh whever whm whse what whatever which whichever，连接副词：when where hw why whenever wherever hwever
表语从句用来说明主语的身份、性质、品性、特征和状态，常位于系动词（be, becme, appear, seem,lk,sund,feel,get,smell等词）之后。引导表语从句的从属连词有：that（不能省略），whether（不能用if替代），连接代词：wh whever whm whse what whatever which whichever，连接副词：when where hw why whenever wherever hwever连接代词：wh whever whm whse what whatever which whichever，连接副词：when where hw why whenever wherever hwever
同位语从句一般跟在某些名词后面，说明该名词表示的具体内容，可以跟同位语从句的名词通常有news，idea，fact，prmise，questin，dubt，thught，hpe，message，suggestin，wrds（消息），pssibility,decisin等有具体信息含量的抽象名词。引导同位语从句的词通常有连词that，whether，连接代词what，wh。连接副词hw,when,where等。（注：if不能引导同位语从句。）
宾语从句的从属连词主要有三类：that, if, whether（介词后，...与 nt连用）连接代词主要有wh, whm ,whse ,what ,whever ,whmever ,whsever, whatever, whichever，连接副词主要有when,where,why,hw,whenever,wherever,hwever
定语从句，一个简单句跟在一名词或代词后（先行词）进行修饰限定，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，可以指代先行词，在定语从句中充当句子成分。
wh, whm,that的先行词是人的名词或代词，在从句中担任主语或宾语
which, that的先行词是事物的名词或代词，在从句中担任主语或宾语
Whse 用来指人或物，表示与先行词之间的所属关系
关系副词when,where,why的先行词是时间、地点或理由的名词，在从句中作状语。
状语从句的分类及引导词1. 时间状语从句：when, while, after, befre, until, since2. 地点状语从句：where3. 原因状语从句：because, since, fr, as4. 条件状语从句：if, unless5. 目的状语从句：, 让步状语从句：thugh, althugh, even if, even thugh7. 比较状语从句：as(同级比较), than8. 方式状语从句：as, as if, hw9. 结果状语从句：s that, in rder that判断状语从句的引导词关键是理顺前后两句话的逻辑关系。
