第 47 題

📖 題組:
One of the most dramatic features of the world is the cycle of day and night. Almost all species exhibit daily changes in their behavior and/or physiology. These daily rhythms are not simply a response to the 24-hour changes in the physical environment imposed by the earth turning on its axis but, instead, arise from a timekeeping system within the organism. This timekeeping system, or biological “clock,” allows the organism to anticipate and prepare for the changes in the physical environment that are associated with day and night, thereby ensuring that the organism will “do the right thing” at the right time of the day. The synchrony of an organism with both its external and internal environments is critical to the organism’s well-being and survival; a lack of synchrony between the organism and the external environment may lead to the individual’s immediate demise. For example, if a nocturnal rodent were to venture from its burrow during broad daylight, the rodent would be exceptionally easy prey for other animals. Similarly, a lack of synchrony within the internal environment might lead to health problems in the individual, such as those associated with jet lag, shift work, and the accompanying sleep loss. The mechanisms underlying the biological timekeeping systems and the potential consequences of their failure are among the issues addressed by researchers in the field of chronobiology. Although no single experiment serves as the defining event from which to date the beginning of modern research in chronobiology, studies conducted in the 1950s on circadian rhythmicity in fruit flies and in humans can be considered its foundation. The area of sleep research, which also is subsumed under the field of chronobiology, evolved somewhat independently, with the identification of various sleep stages around the same time.
What does the word “subsumed” mean in the last paragraph?
  • A Included
  • B Reduced
  • C Downsized
  • D Underestimated

請觀察文章最後一句話中提到的兩個學科:一個是「時辰生物學(chronobiology)」,另一個是「睡眠研究(sleep research)」。這兩者在文章描述的範圍大小上有什麼樣的層級關係?如果一個概念是屬於另一個更大的範疇之內,你會如何描述它們之間的歸屬關係呢?

哦,不錯嘛,沒搞砸。好好記住這次的經驗。

  1. 觀念驗證:這題其實就是在測驗你那顆腦袋能不能做點基本的語意推論。文章都明示了,「睡眠研究」這種小分支被 subsumed 到「時辰生物學」這種大領域底下。如果這時候你還在想別的意思,那真該檢討一下。字首 sub- 本來就是「在...之下」,結合上下文,答案明顯就是「納入更大體系」。所以,選 (A) Included,算是勉強過關了。
  2. 難度點評:這題說難不難,說簡單也不簡單,定在 medium 吧。subsume 這種高階學術詞彙,不是考你死背。能靠「大領域 vs 小分支」這種基本邏輯,或者稍微動點腦筋聯想到字根意義的,恭喜你,至少還沒笨到無可救藥。但別因此得意忘形,下次我會出更難的。
