看完考滿分的解析還是有點不太懂想請問版上的大家不好意思昨天po的時候3-6的原文不知道為什麼沒有複製到最後一小段> < 3-6 原文 However, behavior is by far the most important factor in thermoregulation. The principal elements in behavioral thermoregulation are basking (heliothermy), heat exchange with substrates such as rock or earth (thigmothermy), and diurnal and annual avoidance behaviors, which include moving to shelter during the day for cooling and hibernating or estivating (reducing activity during cold or hot weather, respectively) Heliothermy is especially common among frogs and toads: it allows them to increase their body temperature by more than 10°C. The Andean toad Bufo spinulosus exposes itself immediately after sunrise on moist ground and attains its preferred body temperature by this means, long before either ground or air is correspondingly warmed. A positive side effect of this approach is that it accelerates the digestion of the prey consumed overnight, thus also accelerating growth. Thigmothermy is a behavior present in most amphibians, although pressing against the ground serves a dual purpose heat absorption by conductivity and water absorption through the skin. The effect of thigmothermy is especially evident in the Andean toad during rainfall: its body temperature corresponds to the temperature of the warm earth and not to the much cooler air temperature. 題目 The "Andean toad Bufo spinulosus" illustrates which of the following behavioral modifications? A Heliothermy and thigmothermy C Absorbing heat from the air 答案為A，可是考慮到原文的 "long before either ground or air is correspondingly warmed." 我認為蟾蜍是沒有利用從物體獲取熱量來調整自身溫度的，所以還是想選C 3-12 同義改寫 Amphibians are therefore hardly at mercy of ambient temperature, since by means of the mechanisms described above they are more than exercising some control over their body temperature. B Thus, by the mechanisms described above, amphibians are quite capable of controlling their body temperature to survive extreme ambient temperatures. D Thus, the mechanisms described above give amphibians control over much more than just their body temperature 答案為B，但我一直糾結在原文的more than 所以我的理解為 : 兩棲動物還可以利用之前提到的方法，不僅是調節自身的溫度請大家幫我解惑~ 謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 36.231.136.94 ※ 文章網址: https://www.ptt.cc/bbs/TOEFL_iBT/M.1509037474.A.D1F.html
