沒有謂語從句，這裡做定語從句和同位語從句的區別。

定語從句 的先行詞在從句中充當成分,同謂語從句的先行詞在從句中不充當成分.這是最容易的區分方法.

eg: I was told the news that was published in the newspaper.(這裡定語從句的先行詞that在從句中做主語)

I was told the news that the president had been murdered.(這裡同謂語從句的先行詞that在從句中不充當成分,只是引導從句.)

同時同謂語從句的先行詞只有that而且不可以省略,定語從句的先行詞有多種形式,如that which where whose how..等等)

沒有謂語從句，

謂語是由動詞構成的，根據人稱，時態，語態和語氣在句子中進行相應變化。。
