Re: [問題] 搞不清楚這篇題目要怎麼答
※ 引述《windmoto (moto)》之銘言：
: The following is a letter to the editor of an environmental magazine.
: “The decline in the numbers of amphibians worldwide clearly indicates the
: global pollution of water and air. Two studies of amphibians in Yosemite
: National Park in California confirm my conclusion. In 1915 there were seven
: species of amphibians in the park, and there were abundant numbers of each
: species. However, in 1992 there were only four species of amphibians observed
: in the park, and the numbers of each species were drastically reduced. The
: decline in Yosemite has been blamed on the introduction of trout into the park
: ’s waters, which began in 1920 (trout are known to eat amphibian eggs). But
: the introduction of trout cannot be the real reason for the Yosemite decline
: because it does not explain the worldwide decline.”
: 小弟不才,剛剛在練習AWA的時候遇到這題,想了很久不知道從何下手,
: 因為題目已經說了一個理由且說這並不能解釋全球的問題,
: 所以我是要找出三個理由說the introduction of trout的確是全球的問題而不僅僅是在
: Yosemite這個地方嗎?
: 或者從哪些點可以切入說作者的邏輯有問題呢?
: 請各位神勇的鄉民指點一下!!
我的想法是：
1.study錯。
前面說amphibians的減少清楚指出是因為水跟空氣污染，
但是兩個study都無法confirm author的conclusion.
2.最後一行因果錯。
原文說trout不是造成在Yosemite的amphibian減少之原因，
因為其不能用來解釋全世界amphibian的減少。
--> 但不能用來解釋全世界amphibian減少，
不代表說Yosemite的amphibian的減少就不是trout造成的。
3.在Yosemite的amphibians的減少，可能有其它因素，而非trout造成。
(例如：其它天敵、遊客變多製造髒亂)
4.不能用區域性的現象來解釋全球性的問題，author必須提出更多證據。
不知道這樣寫對不對
有錯請指正!
