问题 Many rare species of plants and animals are threatened with ______ with the worsening of environment and mass hunting.

选项 A、migration
B、extinction
C、distinction
D、distraction

答案 B

解析 逻辑关系题:因果。句中后一个with引起的介词短语构成前面部分的原因;be threatened with是惯用表达方式,相当于be likely to be harmed or destroyed by,threaten一词也暗示了所填词的消极意义。选项中只有[B]extinction“(生物等的)灭绝”含有消极意义,符合题意要求。[A]migration“迁徙”,[C]distinction“差别,特性”,[D]distraction“困惑,娱乐,分心”。
