'The following appeared as an editorial in a wildlife journal. "Arctic deer live on islands in Canada's arctic region. They search for food by moving over ice from island to island during the course of a year. Their habitat is limited to areas warm enough to sustain the plants on which they feed, and cold enough, at least some of the year, for the ice to cover the sea separating the islands, allowing the deer to travel over it. Unfortunately, according to reports from local hunters, the deer populations are declining. Since these reports coincide with recent global warming trends that have caused the sea ice to melt, we can conclude that the decline in arctic deer populations is the result of deer being unable to follow their age-old migration patterns across the frozen sea." '下面這篇文章是一本野生生物雜誌的評論.「馴鹿生活於加拿大極地地區．他們會穿越海面上的冰而從一個島遷徙到另一個島，以找尋食物．他們的生活習慣使得他們只能侷限在某些特定的區域，這些區域必須夠暖，使他們賴以維生的植物能夠生長，但也在某些時候必須夠冷，讓分離各島嶼的海面結冰，這些馴鹿才能穿越冰塊遷徙到他處．不幸的是，當地獵戶指出，馴鹿族群的數量一直在下降．因為這份報告在時間點上恰巧與最近造成海面冰塊熔化的全球暖化趨勢吻合，我們認為馴鹿族群數量的減少，是因為馴鹿再也無法遵循這種穿越結冰的海的古老生活方式．」在練習碰到的一題，想請問大家會從何處切入反駁我目前找到的反駁論點有：一、deer無法遵循這種穿越結冰的海的古老生活方式，不一定和deer數量的減少有關，減少可能還有其他因素，像掠食者、疾病之類的。二、並沒有實際數據指出deer數量在減少，當地獵戶看到的deer可能只是一部份。三、從缺..Orz 不知道大家會從何處切入反駁，我覺得我的第二點好像不夠有力...= =a 先在這謝謝大家了祝大家考試順利 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.115.207.10
