问题    Our universe is dotted with over 100 billion galaxies, and each one contains roughly 100 billion stars. It is unclear how many planets are orbiting these stars, but it is certain that at least one of them has evolved life. In particular, there is a life form that has had the capacity and courage to speculate about the origin of this vast universe.
   Humans have been staring up into space for thousands of generations, but we are privileged to be part of the first generation who can claim to have a respectable, rational and coherent description for the creation and evolution of the universe. 【F1】The Big Bang model offers an elegant explanation of the origin of everything we see in the night sky, making it one of the greatest achievements of the human intellect and spirit. It is the consequence of an endless curiosity, a fabulous imagination, acute observation and ruthless logic.
   Even more wonderful is that the Big Bang model can be understood by everyone. When I first learned about the Big Bang as a teenager, 【F2】I was astonished by its simplicity and beauty, and by the fact that it was built on principles which, to a very large extent, did not go beyond the physics I was already learning at school. 【F3】Just as Charles Darwin’s theory of natural selection is both fundamental and comprehensible to most intelligent people, the Big Bang model can be explained in terms that will make sense to non-specialists, without having to water down the key concepts within the theory.
   But before encountering the earliest stirrings of the Big Bang model, it is necessary to lay some groundwork. 【F4】The Big Bang model of the universe was developed over the last hundred years, and this was only possible because twentieth-century breakthroughs were built upon a foundation of astronomy constructed in previous centuries. In turn, these theories and observations of the sky were set within a scientific framework that had been diligently crafted over two thousand years. Going back even further, the scientific method as a path to objective truth about the material world could start to blossom only when the role of myths and legends had begun to decline. 【F5】All in all, the roots of the Big Bang model and the desire for a scientific theory of the universe can be traced right back to the decline of the ancient mythological view of the world.
【F3】
选项
答案正如对于大多数聪明人而言，达尔文的自然选择论既基础又易懂，大爆炸宇宙模型也可以用非专业术语进行解释，且不会妨碍对该理论重要概念的理解。
解析 ①本句为主从复合句，带有一个方式状语从句。主句中包含一个由that引导的定语从句。②Just as意思是“正如……”，引导方式状语从句，把达尔文的自然选择论跟宇宙大爆炸模型作比较。从句句末的to most intelligent people作状语，表示从句限定的对象是什么，此处intelligent表示“有智慧的；聪明的”。③主句部分在后面，can be explained in terms意思是“能以……术语解释”，后面的定语从句修饰terms，指出这些术语的特点是：能被非专业人士理解。④介词短语without having…作状语，表示“伴随”。
