一、理論常識

同位語從句是對其前面的抽象名詞(例如：idea , insistence , instruction , order , plan , proposal等)進行解釋說明，被解釋說明的詞和同位語在邏輯上是主表關系。同位語從句的結(jié)構一定是先行詞加引導詞加上從句的構成，that并不是可以引導同位語從句的引導詞，whether , why , who . 從句一定要具有完整的句子結(jié)構，主謂賓都必須齊全，引導詞不充當任何成分。

常見先行詞：

belief , fact , hope , idea , doubt , news , rumor , conclusion , evidence ,suggestion , problem , order , answer , decision , discovery , explanation , information , knowledge , law , opinion , truth , promise , report , thought , statement , rule , possibility .
