For one thing, no population can be driven entirely by density-independent factors all the time.难句类型:正话反说
请思考:如果文中说这句话的前提是:all population are driven by two categories of growth parameters, one is density-independent factors, and the other is density-independent factors. 那么作者说上面的这句话有什么用意。
解释:本句虽然貌不惊人,但本书既然将其收录进来,并标出难度5,就意味着其中有怪异之处。值得一提的是,本文前面曾把控制种群密度的因素分为两种,一种叫做density-dependent factors,另一种叫做dentsity-independent factors。原文的直译虽然好懂,但是总令人感觉说得不甚明白。显然,GRE或GMAT的作者不可能随便说一句无关痛痒的话,那么没有任何种群能够在所有的时间全被d-I因素所控制,其真正意思是什么呢?就是:一切种群都必然在某个时间内受到d-d因素的控制。本句是ETS在考试中惯用的正话反说的典型例子,请读者深沉体会。本句在文章中也是理解作者态度的关键所在。
意群训练:For one thing, no population can be driven entirely by density-independent factors all the time.
