问题 Within the foreseeable future there may be a major ______ of species, involving from one-third to two-thirds of all the species now in existence.

选项 A、exhaustion
B、exhibition
C、extension
D、extinction

答案 D

解析 在不久的将来可能会有物种的灭绝,包括现存的1/3~2/3的物种都会濒临灭绝。这道题考查学生辨别形近词的能力,这四个词长得很像,但意思却大相径庭:exhaustion耗尽,exhibition展览,extension拓展,extinction灭绝。
