问题
Many rare species of plants and animals are threatened with ______ with the worsening of environment and mass hunting.
选项
A、extinction
B、migration
C、destruction
D、extraction
答案
A
解析
逻辑关系题:因果。物种数量本已很少,再加上环境恶化和大规模的狩猎,它们面临的应该是物种灭绝的威胁。[A]extinction“灭绝”符合题意。[B]migration“移民”、[C]destruction“破坏”、[D]extraction“抽出,提取”均与句意不符。
