※ 引述《vincactusi (吸)》之銘言： : 2.Some species of Arctic birds are threatened by recent sharp increases in the : population of snow geese, which breed in the Arctic and are displacing birds : of less vigorous species. Although snow geese are a popular quarry for hunters : in the southern regions where they hunter, the hunting season ends if and when : hunting has reduced the population by five percent, according to official : estimates. Clearly, dropping this restriction would allow the other species : to recover. : Which of the following, if true, most seriously undermines the argument? : 答案是 : B. It has been many years since the restriction led to the hunting season for : snow geese being closed earlier than the scheduled date. : 我不懂為什麼? 我剛剛看完了CD上的討論 http://forum.chasedream.com/dispbbs.asp?boardID=24&ID=141943&page=7 說實在我也不太確定這樣對不對 但是B似乎是在考文法 It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date. 桃紅色的字是說，以下這件事情 hunting season 提早結束，表示雪鵝被殺的比預期快，取消限制就會被殺更多 但是這件事情呢 已經是好幾年前的事情了 所以雪鵝被殺很多，是幾年前的事了 → 現在沒那麼受歡迎了 → 取消限制也不會有用 故反駁原文 其他答案我覺得都明顯錯，或是跟打獵無關 A: Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese. 這個限制是好多年前就已經實施的 C: The number of snow geese taken by hunters each year has grown every year for several years. 每年雪鵝被捕的量越來越多 → 支持原文 D: As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons. 因為雪鵝數量增加，他們又開始用了好久沒用的冬天棲息地 E: In the snow goose’s winter habitats, the goose faces no significant natural predation. 在雪鵝的冬天棲息地，他們沒有主要的天然捕食 (看不太懂) -- 別忘了. 山谷裡. 寂寞的. 角落裡 --
