4周搞定2000+托福核心词
eccentricity = ecto(外部的) + centr(中心) + ic(…的) + ity(表性质) = 离开中心→古怪
ectothermic = ecto(外部的) + therm(热) + ic(…的) = 随着外部变化温度的→变温的
poikilothermal = poikilo(变化的) + therm(热) + al(...的) = 变温的
endothermic = endo(内部的) + therm(热) + ic(…的) = 温血的
外部从热变冷→变温动物
ectotherm
常考释义
n. 冷血动物；变温动物
An organism, such as a fish or reptile, having a body temperature that varies with the temperature of its surroundings; an ectotherm.
变温动物一 种体温随周围环境的 温度变化的生物体，如鱼或爬行动物；
Right! All animals are considered either endotherms or ectotherms.
对的！所有的动物都可以被划分成恒温的和变温的。
来源于：听力OFFICIAL37 L6Therm-that means heat, and the main thing that distinguishes endotherms from ectotherms is the source of body heat.
这两个术语的意思是体温是不是热的，还有，区分恒温动物和变温动物的主要依据之一就是体温的来源。
来源于：听力OFFICIAL37 L6And an ectotherm, ecto- meaning external, an ectotherm gets its body heat mainly from outside its own body, meaning from its environment, mostly from the sun's radiation.
And an ectotherm, ecto- meaning external, an ectotherm gets its body heat mainly from outside its own body, meaning from its environment, mostly from the sun's radiation.
来源于：听力OFFICIAL37 L6I mean, the metabolic rate of an endotherm, say, a mouse, is at least six or seven times that of an ectotherm of a similar size like a frog or a lizard.
我的意思是，一个恒温动物的新陈代谢速率，比如说一只老鼠的，至少是相同体型的青蛙或蜥蜴的六七倍。
来源于：听力OFFICIAL37 L6An ectotherm doesn't generate nearly as much heat internally.
一只变温动物并不主要靠身体内部产热。
来源于：听力OFFICIAL37 L6It's by means of such behavior that an ectotherm like this lizard regulates its temperature.
就是因为这种行为，像这种蜥蜴一样的变温动物可以做到调节自己的体温。
来源于：听力OFFICIAL37 L6But an ectotherm probably wouldn't survive in a place where the temperatures got too low, right?
But an ectotherm probably wouldn't survive in a place where the temperatures got too low, right?
来源于：听力OFFICIAL37 L6It's not what we endotherms do that keeps our temperatures within range, unlike ectotherms.
