【题目】After the deadly collision, the relatives of the kids protected them from the knowledge_______ their parents had already passed away.
A.whenB.whereC.thatD.which
在线课程【答案】C
【解析】
考查同位语从句。句意：在那次致命的撞车之后，孩子们的亲属保护他们，不让他们知道他们的父母已经去世了。their parents had already passed away.是一个同位语从句，解释前面的抽象名词knowledge。引导词在从句中不作任何成分，也没有实际意义，故选C。
