问题 Nevertheless, researchers of the Pleistocene epoch have developed all sorts of more or less fanciful model schemes of how they would have arranged the Ice Age______in charge of events.
选项 A、they had been
B、had they been
C、they had have been
D、were they
答案B
解析 本题为考查虚拟语气倒装的用法。how引导了两个倒装的句子，正常语序应是“Ifthey had been in charge of events，they would have arranged the Ice Age in certain model schemes．”由于model schemes做主句谓语动词developed后面的宾语，how引导的定语从句修饰宾语，形成倒装。if引导的虚拟从句，在省略if时，谓语动词提到主语前面，形成主谓倒装。本句中had提到they前面，形成had they been的倒装结构。因此，B选项正确。
