59. 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 had they been in charge of events.(3+) 然而，研究P时代的研究者发展除了各种各样的或多或少有些奇怪思想的模型系统，用来显示如果由他们来决定地质事件的话他们将会如何安排冰川纪。

　　难句类型：复杂修饰、倒装、修辞

　　解释：句末的由how引导的名词性从句中包括了双重的倒装，正常的语序本来是：If they had been in charge of events, they would have arranged the Ice Age in certain model schemes。本句中由于arrange的方式被提前，就造成了arrange的动作执行者也要提前，前面的if they had been 则必须后置;这样一来又造成了if被省略，成为had they been的倒装结构。 另外，作者为了表达其对于这些研究者的模型的负态度，并炫耀其幽默感，在本句中使用了虚拟语气，并使用了fanciful这个词以表示这些研究的不负责任、异想天开的幼童心理。

　　意群训练：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 had they been in charge of events.
