1.主语从句
例句： The person gave me a free ride is the lorry driver.
1）句子本身没有语法错误，但是这不是主语从句，只要把它化简分析就可以一目了然：
* 句子的主要成分：The person is the lorry driver. 主系表结构。
* 过去分词短语 gave me a free ride 是 the person 的后置定语，也可以改为定语从句：(the person) who gave me a free ride ,意思是“让我免费乘坐的（那个人）”。
2）所谓主语从句指的是用句子作主语，或者是把主语扩展成一个句子，引导主语从句有四种情况：
that 从句 —— 用来陈述一个事实，如：
* That the person gave me a free ride / is known to you. 那个人让我免费乘坐这件事你已经知道。
wh- 从句：陈述已知的具体问题，如：
* How the person gave me a free ride / is known to you. 那个人怎么让我免费乘坐你已经知道。
if/whether 从句：陈述未知的或然问题，如：
* If/whether the person gave me a free ride / was still not known. 那个人是否让我免费乘坐还是个未知数。
关系代词型从句：表示“所...的（东西、事情、话等）”
* What he said / was not quite right. 他所说的不完全正确。
另外前三种从句都可以用形式主语 it 改写：
* It is known to you / that the person gave me a free ride.
* It is known to you / how the person gave me a free ride.
* It is known to you / whether/if the person gave me a free ride.

2. 宾语从句
例句：I heard that a lorry driver gave you a free ride.
这是一个标准的宾语从句。除 that 引导外，也可以用上述的其它三种引导。

3. 表语从句
例句：The lorry driver is who gave me a free ride.
这个句子在语法表面很像一个表语从句，但是意思上却说不通。
这类从句的主语只能用表示事情的名词充当，不能用具体的人或东西。举例如下：
* The news I heard is / that the lorry driver gave him a free ride. 我听到的消息时达车司机让他免费乘坐汽车。
* The question is / when the lorry driver will give me a free ride. 问题是卡车司机什么时候让我免费乘坐。
* My doubt is / if the lorry driver will give me a free ride. 我的疑虑是卡车司机是否会让我免费乘坐。

4. 同位语从句
例句：I heard the story that a lorry driver gave you a free ride.
正确。

归纳：以上的从句统称为名词从句，名词从句有四种类型（已经在主语从句做过介绍）。
1）that 从句；
2）wh-从句（包括when, where, why, who, which 和 how）；
3）if/whether从句；
4）关系代词性从句（包括what/whatever——所...的东西、事情、话等；where/wherever——所...的地方；when/whenever——所...的时间；）

5. 定语从句
例句：This is the lorry driver who gave me a free ride.
正确。

6. 状语从句
例句：I thanked the lorry driver because he gave me a free ride.（原因状语）
正确。
