Question

(2011·重慶)It is still under discussion ________ the old bus station should be replaced with a modern hotel or not.

A．whether B．when C．which D．where

 

Answer 1

A

【解析】考查主語從句的引導詞。句意：這個舊汽車站是否應該被一個現(xiàn)代化的旅館取代還在討論之中。本句中的It是形式主語，真正的主語是從句“whether the old bus station should be replaced with a modern hotel or not”。whether在句中引導主語從句。
