While some commentators suggest that abstraction and complexity in scientific research are signs that a given direction is misguided, Lisa Randall, a professor of physics at Harvard, counters that these qualities instead reflect the success of human ingenuity in (i) _____ the increasingly (ii) _____ challenges that nature presents. They can, however, make it more (iii) _____ to communicate scientific developments, even to colleague.
Blank (i) Blank (ii) Blank (iii)
A. creating D. difficult G. challenging
B. meeting E. conspicuous H. unproductive
C. eschewing F. pragmatic I. advantageous
答案：B D G
解析：题目翻译成：尽管一些评论员认为，科学研究的抽象性和复杂性表明一个给定的方向是错误的。哈佛大学的物理学教授Lisa Randall反驳说，相反，这些特征反映了人们在成功应对大自然日益困难的挑战方面的创造力。只是，这些特征使科学发展的交流更具挑战性，即使是在同事之间。
第一空是固定搭配，meeting challenges; 所以最恰当的选项是B. eschewing,避开。第二空第三空可由开头的abstraction and complexity推断，大自然的挑战是越来越困难的，科学发展的交流也是越来越有挑战性的。conspicuous，显而易见的;pragmatic，实际的;unproductive,徒劳的，不毛的;advantageous,有利的，有益的，不合题意。
