Before about 1960, virtually all accounts of evolution assumed most adaptation to be a product of selection at the level of populations; recent studies of evolution, however, have found no (i)____ this (ii)____ view of selection.
选项
A、departures from...controversial
B、basis for…pervasive
C、bias toward…unchallenged
D、precursors of…innovative
E、criticisms of…renowned
答案
B
解析
空格(ii):
- 方程等号:this为指示代词,指代分号前的观点,this后指代的内容和前文内容同义重复。
- 强词和对应:前文说几乎所有的观点都认为大多数的适应是生物种群水平上选择的结果,因此空格(ii)描述这个观点的特点,和all取同,体现选择的观点是得到“所有”或“广泛”认可的。controversial有争议的,pervasive普遍的,unchallenged未受到挑战的,innovative创新的,renowned著名的。选项B和C合适。
空格(i):
- 方程等号:however表示转折,反义重复。no取反。两次取反后最终同向。
- 强词和对应:however前说所有的解释都认为适应是选择的产物,however之后对这种观点取反,因为已经有no,所以空格填入一个正向词即可。departure from违反(错),basis for…的基础(对),bias toward对…的偏见(错),precursor of…的先驱(错),criticism of对…批判(错)。综合空格(ii),答案选B。
