非常喜歡 Snark大的常識面解答, 長了知識了, 感謝。
以下提供英文層面的解答, 我認為原PO沒有看懂題目的格式__條件填空題。
: TPO閱讀第一篇
: Speciation in Geographically Isolated Populations
: 第六題
: According to paragraph 3, separation of subpopulations by glaciers resulted
: in speciation in those groups of plants and animals that
: A Were reproductively isolated even after the glaciers disappeared
: B Had adjusted to the old conditions caused by the glaciers
: C Were able to survive being separated from their parent population
: D Had experienced some genetic divergences from their parent population
這是個填空題, 以中文思考的話就是:
冰河的阻隔, 將使speciation會發生在_____的動植物身上。
speciation in those groups of plants and animals THAT後面接的是"空格______"
D 這答案不夠好,
文章中 Some/ other groups 受到冰河阻隔的動植物, 全部都有發生 D選項說的
"some genetic divergences from their parent population"
Some/ other groups區分的標準, 是在於是否差異大到無法在相遇時還能交配繁殖(羞)。
A 的內容就是在說上面很害羞的這一句, 也就是"some groups..."這一組的特性。
最後請容我把題目改一下, 改成跟中文語法習慣比較接近的版本:
According to the parapgraph, (確認是細節題)
in which group of animals and plants (問題點)
did speciation resulted from the subpopulations by glacier (被問的主角)
happen? (發生/動作)
相信所有的鄉民都能輕鬆回答:
是"基因變異大到不能再跟對岸的同胞(??)繁殖" 的那一組, 就是 A
: 第三段是:
: Geographic isolation can also proceed slowly, over great spans of time. We
: find evidence of such extended events in the fossil record, which affords
: glimpse into the breakup of formerly continuous environments. For example,
: during past ice ages, glaciers advanced down through North America and Europe
: and gradually cut off parts of populations from one another. When the
: glaciers retreated, the separated populations of plants and animals came into
: contact again. Some groups that had descended from the same parent population
: were no longer reproductively compatible – they had evolved into separate
: species. In other groups, however, genetic divergences had not proceeded so
: far, and the descendants could still interbreed – for them, reproductive
: isolation was not completed, and so speciation had not occurred.
: 答案是A
: 但我選D
: 因為原文不是寫說冰河退去後，分開的物種又恢復連結
: 但A說Were reproductively isolated even after the glaciers disappeared
: "冰河退去後 物種繁衍被孤立"
: 這樣解釋不是相反了嗎?
