[請益] TPO11第九題關於鳥的防衛巢的行為
第九題題目是
According to the lecture, when do birds put on their most
conscious distraction displays?
A. Just before they lay their eggs.
B. Immedicately after they have laid their eggs.
C. Just before their young become independent.
D. Immedicately after their yound have left the nest.
寄託的答案選A,這答案完全沒出現在原文
比較有可能的答案是B.C
我個人選C
我把原文附上，麻煩高手解惑。
Now, what’s interesting is that birds have different levels of performance,
um, these distraction displays. They don’t give their top performance,
their prime time performance every time. What they do is,
they save their best performances,
their most conspicuous and most risky displays for the time just before
the baby births become able to take care of themselves. （答案在這句話吧）
mbaby births是名詞 become able to take care of themselves
And the time that they wait because that’s when they’ll make the greatest
investment in parenting their young. So, they are not gonna put
on their best performance just after they lay the eggs,
because they haven’t invested that much time or energy in parenting yet.
The top performances are gonna come later. Now, you know some birds that
are quite mature, and quite capable almost as soon as they hatch.
And in that case, the parents would put on the most conspicuous distraction
displays just before the babies hatch, (條件一成立下的另一個可能答案)
because once the babies are hatched, they can pretty take acre of themselves.
And then you’ll have other birds they are
helpless when they hatch, in that case, the parents would save the best
performances until just before the babies get their feathers.（這跟主要情況一致）
大體來說答案應該是幼鳥有辦法獨立照顧自己之前，不知道大家覺得如何?
