本文叙述了在南极洲南乔治亚岛上进行的大规模灭鼠运动。18世纪晚期，海员无意间把老鼠引入到南极洲南乔治亚岛这个清新的环境，为了让鸟类重回这里，他们开始灭鼠。估计这所产生的效益会在几十年的时间里完全实现。
小题1:细节理解题。根据第二段“It was sailors in the late 18th century who unintentionally introduced rats to what had been a fresh environment.”可知是18世纪晚期，海员无意间把老鼠引入到南极洲南乔治亚岛这个清新的环境。故答案选C。
小题2:细节理解题。根据“Some New Zealanders will be helping our campaign, including our chief pilot, Peter Garden, who was also chief pilot for the projects at Campbell Island and Rat Island, ”可知Peter Garden是灭鼠工程的首席飞行员，所以他为Campbell岛和鼠岛的灭鼠工程做出了卓越贡献。故答案选D。
小题3:细节理解题。根据“It is a huge operation, carried out during the stormy southern autumn when the rats are hungry and the risks of poisoning native wildlife are less than in the spring and summer months.”可知这场大规模灭鼠运动在多暴风雨的男方秋季实施，是因为这时候鼠类饥饿，而且毒死本土野生动物的风险比春天和夏天更小。故答案选C。
小题4:推理题。根据“Though rats and mice have done the most damage, cats, foxes, goats, deer, rabbits and other species have been targeted in the campaigns around the world.”尽管鼠类危害最大，猫狐狸山羊鹿兔子和其他物种在全世界范围内被定为目标。可知野生动物的消失不能只归咎于鼠类。故答案选B。
