问题 Evidence suggests that populations of migratory birds in both the New and Old Worlds have (i)________, a (ii)________that carries the potential for significant ecological damage far beyond the shrinking numbers of the birds themselves.
Blank (i)     Blank (i)
A. scattered  D. dispersal
B. stabilized E. decline
C. plummeted  F. displacement
选项
答案E,C
解析 空格关系题。两空格联动。通读句子：东西半球的候鸟数量(populations of migratory birds in both the New and Old Worlds)是(i)________的，(ii)________所带来的生态破坏的潜力远远超过鸟群自身数量的缩减(shrinking)。两个空格之间没有转折词出现，属于顺承关系，后面说比种群缩减(shrinking numbers of the birds themselves)更易导致生态破坏。因此两个空格要体现出与shrinking有关的概念，E项decline，C项plummeted与shrinking同义对应，表示候鸟数量锐减。
