Some paleontologists debate whether the diversity of species has (i)______ since the Cambrian period, or whether imperfections in the fossil record only suggest greater diversity today, while in actuality there has been either (ii)______ or decreased diversity.
选项
A、changed…escalation
B、increased…stasis
C、expanded…discontinuity
D、declined…reduction
E、improved…deviation
答案
B
解析
空格(ii):
- 方程等号:either A or B,A与B反义重复,
- 强词和对应:根据题意,空格(ii)和decreased构成反义重复,体现物种多样性“不下降”,即“上升”或者“不升不降”。escalation增加,stasis停滞,discontinuity不连续,reduction降低,deviation偏离。选项A和B合适。
空格(i):
- 方程等号:whether A or whether B,A与B反义重复。
- 强词和对应:空格(i)和greater构成反义重复。change改变(可能“变多”也可能“变少”,排除),increase增加(对),expand扩展(对),decline下降(错),improve增加(对)。答案选B,在这里increase和greater是程度差异,正确。
