基本上,TOEFL iBT托福閱讀之事實細節 (Factual Detail Information) 題型,作答原則務必先審視題幹之敘述,搜索出關鍵字詞,原文定位,再進行訊息判斷。
以 TPO31 其中一篇閱讀篇章中的題目為例:
以 TPO31 其中一篇閱讀篇章中的題目為例:
Geographic isolation also can proceed
slowly, over great spans of time. We find evidence of such extended events in
the fossil record, which affords glimpses 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.
1. According to this paragraph, 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
根據段落,由冰河所形成次級種群 (subpopulation)之分隔導致在動植物群落中之物種形成(speciation) 為何?
● 關鍵字詞--- glaciers / plants and animals speciation
● 原文定位--- 段落第三句出現 glaciers,整句句首for example概為前句之例證---
因此閱讀前一句訊息 the
breakup of formerly continuous environments (冰河時期冰河造成環境之分隔);其次再定位 plants and
animals。本段第四句訊息後續提及冰河消退時,那些分離之動植物再度接觸時,某些源自相同母種之物種再也無法繁殖出一致性物種(no longer reproductively compatible),因而進化發展出不同之物種。因而判讀答案選項A符合。
A. were reproductively isolated even after the glaciers disappeared
--- 即使冰河消失後該動植物會繁衍生出不同之物種.
●重點單字提醒---
compatible (相符的; 一致的) = consistent = concordant = concurrent = congruous = corresponding = correspondent .
