有三大类 1.名词性从句 2.定语从句 3.状语从句 名词性从句中分： 1.主语从句：例,it is important to read book.(形主it作主语,真正的主语是to read book) that air has pressure was known long ago.(关联词that引导的句子that air has pressure作主语从句) 2.宾语从句：I think it necessary that he should do his homework.(形式宾语it引导的) I'm sure that my test will succeed.(sure后用that引导的宾从) 3.表语从句：系动词后的从句 it may be as you say(be是系动词,后面用as引导的) this is that he is too young to go to school.(有系动词is,后面由that引导的表语从句) 4.同位语从句：同位语从句是对前面名词的解释说明,如： The facts that he had done his homework.(事实就是he had done his homework,是对前面the facts的解释,是什么事实) 定语从句：在句子中起定语作用,修饰剧中的名词或代词的从句叫定从 例：the man (who is shaking hands with my father) is my teacher.(括号中就是定从,修饰限定the man) BeiJin is a city (which has a long history).(括号中是定从,修饰the city) 状语从句：在复合句中担任状语成分的从句叫状语从句 例：I will tell her about that (when i see her).为时间状从 just stay (where you are).为地点状语 Because he is ill,he is absent today.为原因状语 这也很局限,其实要讲的还很多,你可以多看看语法书之类的

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。

1、主语从句

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

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。

3、宾语从句

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

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。

5、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。

6、状语从句

用作状语的从句叫作状语从句，其关联词是一些从属连词。修饰主句中的动词、形容词和副词，通常由从属连词引导，按其意义和作用可分为时间、地点、 条件、 原因、让步、目的、结果、 方式、比较状语从句等。
