TPO17 ANIMAL SIGNALS IN THE RAIN FOREST - 英檢

※ 引述《buda (逆趨勢者套)》之銘言：
: 想請教該文中一個很tricky的INFER題：
閱讀一定要注意時態
原文想要表達的意思是這樣的
請注意我選起來的字

: Paragraph 4: Very little light filters through the canopy of leaves and
: branches in a rain forest to reach ground level—or close to the ground—and
at those levels the [yellow-to-green wavelengths predominate].

A signal [might] be most easily seen if it is maximally bright. In the green-to yellow
: lighting conditions of the lowest levels of the forest, yellow and green
: would be the brightest colors,
[but when an animal is signaling, these colors
would not be very visible] if the animal was sitting in an area with a
: yellowish or greenish background
:The best signal depends not only on its brightness
[but also on how well it contrasts with the background against]
: which it must be seen.

In this part of the rain forest, therefore,
[red and orange are the best colors for signaling], and they are the colors used in
: signals by the ground-walking Australian brush turkey. This species, which
: lives in the rain forests and scrublands of the east coast of Australia, has
: a brown to-black plumage with bare,
[bright-red skin] on the head and neck and
: a neck collar of
[orange-yellow] loosely hanging skin. During courtship and
: aggressive displays, the turkey enlarges its colored neck collar by inflating
: sacs in the neck region and then flings about a pendulous part of the colored
: signaling apparatus as it utters calls designed to attract or repel. This
: impressive display is
[clearly visible] in the light spectrum illuminating the
: forest floor.


您沒有抓到正確的轉折點
當看到 A signal [might] be most easily seen if
其實就是要說這不是正確的 或 被推翻的理論
在寫研究型論文的時候每一種時態都有不同的意義 後面又加上 if 條件
所以我不會注意這個訊息

之後果然寫
[but when an animal is signaling, these colors
would not be very visible]
these colors=Yellow and green

您選的 The best signal depends not only on its brightness
就是要說這件事 雖然森林底層的光線主要是 Yellow and green
所以反射Yellow and green的物體看來最亮
但是由於背景都是Yellow and green
反而不明顯

所以最好的訊號色不光只是亮度高的
而是對比明顯的
how well it contrasts with the background

In this part of the rain forest, therefore,
[red and orange are the best colors for signaling]
之後的生物都是用來支持此例子
所以這題只是考段落大意 並不是細節

很多戰友以為自己月讀太慢
其實可能是看了太多不必要的資訊
一定要瞭解作者想傳達的意思
注意句子之間的關係
: Q9. Which of the following can be inferred from paragraph 4 about yellow and
: green colors compared with red and orange colors at the bottom of the forest?
從文中可以推論 黃.綠 相較於 紅.橙 在森林底層的的對比 是...
: ○Yellow and green are better colors for signaling than red and orange
: colors.
錯 紅.橙 較好 有動物的顏色當例子
: ○Orange and red are brighter colors than yellow and green.
這不是問顏色本身的亮度
問的是森林底層的狀況 所以yellow and green 比較亮
原文有寫
: ○Yellow and green are likely to be more common in the background than red
: and orange.
雖然原文說 光線中yellow and green wavelengths predominate
卻不是只有這兩個顏色的光線
其實森林底層仍是彩色的 只是其他顏色相對較弱 換言之你還是能看到灰色的石頭
咖啡色的樹幹 並沒有說森林的背景只有黃.綠色
而是其他顏色 會相對較黯淡

能推論出森林底層的背景顏色
是因為 有這個條件句
these colors would not be very visible if the animal was sitting in an area
with a yellowish or greenish background
這個條件是否成立
看森林中的動物選用來傳訊息的顏色就知道了
光的原色是 紅 綠 藍 (黃＝綠+紅)
所以既然動物能用紅色與橘色 傳訊
就表示背景應該是綠色為主
這樣雖然紅光亮度較低 卻很明顯
( 黃光之中有紅光的成分 橙＝紅＋黃)
因此推論 應該是綠.黃 > 紅.橙

: ○Orange and red colors do not contrast as well with the forest floor as
: yellow and green do.
: 我的判斷是根據文中的
: The best signal depends not only on its brightness but also on how well it
: contrasts with the background against which it must be seen. 的前後文
: 所以我選擇A
: 但是正解為C
: 可是我覺得C根本不叫暗示，在該段第一句就說了
: "those levels the yellow-to-green wavelengths predominate"
: 不知做過該篇的大大有沒有這樣的問題？？
: 在下先謝過了~~
