同位语是位于所修饰的名词之后,对该名词起进一步说明或解释的作用。同位语可以用单词或短语表示,也可以用从句表示如:同位语的表现形式有以下几种:
(1) 单词
I myself will do the experiment.
(2) 短语
This is Mr. Black, director of our company.
(3) 句子
The question what we should do next hasn't been considered. 二. 同位语从句the Appositive clause

When was Dolly the sheep born?因为谓语部分很短,为了起到平衡句子的作用,把被修饰的名词和起修饰作用的同位语从句分隔开了,该形式容易被忽视。注意:Word/News came that our basketball team had won.
