It was never clear _______ the man hadn’t reported the accident sooner.
A.thatB.howC.whenD.why
D
D【命题动向】考查名词性从句。
解析一:It做形式主语,真实主语由后面的句子来充当。从主语从句的句子成分看,表示原因是最恰当的。句意为:那个人并没有早点儿报告这次事故,其原因还不清楚。
解析二:本题意为“不清楚为什么这个男人没有及早汇报这个事故。”it是本句的形式主语,why引导的从句是真正的主语,表示原因。B选项放在句中句意不通,C选项when表示一个时间点,不能和完成时连用。A选项that放在句中句意不通。
