【题目】The explorer entered the cave, ____ was like a sleeping bag pulled over his head.
A.whose darknessB.its darknessC.darkness of whichD.which darkness
在线课程【答案】A
【解析】
考查定语从句。句意：探险者进入洞穴，洞里一片漆黑，就像一个睡袋套在他的头上。分析句子结构可知，此处是定语从句，从句的主语是“它的黑暗”先行词cave作定语从句的定语。故用whose darkness/the darkness of which/of which the darkness。故选A项。
