[問題]GWD 7-21

[la-vie]

better maneuver=操縱飛行的技術較好(意指可能飛的慢,但是飛的很平穩等等的)
這樣解釋行嘛?
還是想太多阿???????????????

我也是這樣想的說

[quote="James"]Which of the following most logically completes the passage?


Each species of moth has an optimal body temperature for effective flight, and when air temperatures fall much below that temperature, the moths typically have to remain inactive on vegetation for extended periods, leaving them highly vulnerable to predators. In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why ______.




(A)large moths are generally able to maneuver better in flight than smaller moths
(B)large moths are proportionally much more common in warm climates than in cool climates
(C)small moths are more likely than large moths to be effectively camouflaged while on vegetation
(D)large moths typically have wings that are larger in proportion to their body size than smaller moths do
(E)most predators of moths prey not only on several different species of moth but also on various species of other insects[/list]

這題我總覺得是A
higher optimal body temperatures 較能適應溫度變化 所以飛行技術好
也呼應了前面說的hence have a better chance of evading flying predators 和can fly faster than smaller ones 怎麼看都覺得這選項很完美

B 選項似乎是騙人的答案 難道小娥就不能選擇較高溫的環境 對它飛行也有利阿

有沒有人有其他看法 更好的解釋

"higher optimal body temperatures 較能適應溫度變化 所以飛行技術好"
好像有點誤解: 題目是說如果氣溫低於體溫,蛾就變得行動遲緩,容易被吃掉.
(B) 大蛾因為體溫較高,所以活在較暖和的地方,好保持活力,避免被吃掉.

題幹：體溫相關

與溫度無關選項：ACDE

[chris720503]

依題意： 大蛾因體溫高飛得較快，但易低於周圍環境的溫度而維持在inactive的狀態，也更容易被獵食。小娥體因溫較低而飛得慢，容易被捕食，但因不易低於環境中溫度而較不會 remain inactive。

我認為關鍵字為 but: 表示前後兩個句子是對比關係
In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why ______.
(A) 句意比較適合用 and連接
(C) 小蛾因為不容易 remain inactive 所以更不需偽裝
(B) 句意符合 but 的結構。 其實就是指大蛾或小蛾都有各自的優缺點。
