同位语：表示对一个名词或代词进行解释或补充说明的词。

同位语从句：

指的是在复合句中充当同位语的从句，属于名词性从句的范畴; 同位语从句用来对其前面的抽象名词进行解释, 说明该抽象名词的具体内容。

（同位语从句跟在__名___词后面，并对其进行__解释说明_）

四．引导同位语从句的连接词

	功能	例词
从属连词	只起连接作用，不充当从句中的任何成分。	that, whether
连接代词	既起连接作用，又在从句中担任成分（主语、宾语、表语或定语）。	who, what, whose, which, whom
连接副词	既起连接作用，又在从句中担任成分（状语）。	when,  where, why, how

1）从属连词

that : __无__意义、___无___成分、__不可_____省略，只起连接作用

whether: __有___意义、___无___成分、____不可___省略

I gave her a promise that I would come back after two days.

2）连接代词

who, what, whose, which, whom

既起连接作用，又在从句中担任成分（主语、宾语、表语或定语）。

They had no idea ____what______ time they were supposed to arrive.

3)连接副词

when,  where, why, how

既起连接作用，又在从句中担任成分（状语）。

特别提示:

①who，what，whose，which通常不引导同位语从句。

②同位语从句有时不紧跟在它说明的名词后面，而是被别的词隔开。

五．常见句式

Word came that…    消息传来说…

News came that…    消息传来说…

A story goes that…  传说…

A saying goes that…有一句谚语说…

六．虚拟语气

当名词为表示命令、建议、要求等词时，从句谓语要用(should)+动原。

1.His suggestion that we (should) have a map is reasonable.

2.The command that a meeting (should) be held before the event is from the president.

方法点拨:从句缺什么补什么

1. 看整个从句在主句中做什么成分（主、宾、表、同)，从而确定从句名称。

2. 看从句本身是否完整。

a. 若从句完整（不缺主宾表定)考虑用从属连词和连接副词

b. 若从句不完整（缺主宾表定）考虑用连接代词
