It has been many years since something occured....... 代表 something occured 到現在都沒發生 For example: It has been many years since I saw you last time --> 從上次看到你到現在已經很多年了 --> 這幾年都沒看到你所以 (B) 是指: 上次禁令讓 hunting season closed early 到現在很多年了 --> 這幾年禁令都沒有都沒有實施過不管沒有實施的原因為何但證明了結論的 "dropping the restriction" 不會有任何影響 ※ 引述《SagiCapri (Hello~)》之銘言： : 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 winter, 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? : A Hunting limits for snow geese were imposed many years ago in response to a : sharp decline in the population of snow geese. : B It has been many years since the restriction led to the hunting season for : snow geese being closed earlier than the scheduled date. : C The number of snow geese taken by hunters each year has grown every year for : several years. : D As their population has increased, snow geese have recolonized wintering : grounds that they had not used for several seasons. : E In the snow goose's winter habitats, the goose faces no significant natural : predation. : OA: B : 某種北極圈的鳥因為雪雁數量遽增而遭受威脅。 : 即使雪雁在過冬時常常被獵捕， : 一旦雪雁數量因為獵捕而減少了5%時，狩獵季節則停止。 : 因此，廢除這個限制能讓其他物種生存。問削弱 : (不是很清楚B的意思 : 是說，過去幾年以來，由於這個限制導致狩獵季節提前結束　嗎？ : 暗指雪雁被獵捕的數量比預期的還早達到5%？) : 想請問選項B的意思以及如何weaken! 謝謝!! -- Dounts 機經班: http://ppt.cc/TeAz -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 180.176.240.33 ※ 編輯: dounts 來自: 180.176.240.33 (08/18 22:37)
