If a species of parasite is to survive, the host organisms must live long enough for the parasite to (i)______; if the host species becomes (ii)______, so do its parasites.
选项
A、atrophy…healthy
B、reproduce...extinct
C、disappear…widespread
D、succumb…nonviable
E、mate…infertile
答案
B
解析
空格(i):
- 方程等号:if引导条件状语从句,前后句意同义重复。
-强词和对应:空格(i)和survive根据if取同,体现如果寄生虫的种类要存活,寄主必须活得足够长以保证寄生虫的“生存”。atrophy萎缩,reproduce繁殖,disappear消失,succumb死亡,mate交配。选项B和E合适。
空格(ii):
- 方程等号:分号说明前后句意同义重复。if引导条件状语从句,前后句意同义重复。
- 强词和对应:空格(ii)和survive构成反义重复或者同义重复,体现寄生虫的生存和寄主的生存是正相关的。选项B的意思是如果宿主灭绝,寄生虫也会绝种,正确;而选项E说如果宿主不育,寄生虫也不育,这一点显然很荒谬,所以排除E,答案选B。
-healthy健康的,widespread广泛的,nonviable不能生存的。
