同位语从句与定语从句的区分

1)The proposal that he put forward is to be discussed at the meeting．

2)The proposal that we should hold sports meeting is to be discussed．

a．句1)是________从句，that在从句中________成分，句2)是________从句，that在从句中________成分，而且一般不省掉。

b．定语从句用来说明先行词的性质特征，起修饰或限制作用；同位语从句用来解释说明句词的内容，二者是________关系。

c．区分时可以在先行词与从句之间加一个系动词be，使之构成一个新句子，如果句子通顺且符合逻辑，则为同位语从句，反之，则为定语从句。

例如：The report that he was going to resign was false．他将辞职的传闻是假的。因为the report was that he was going to resign句意通顺，所以，that he was going to resign是同位语从句。
