TED演讲-口语练习：了解运动中的热应激

在TED演讲节目中，演讲者清晰的口语表达及其内容的写作手法都是值得我们学习借鉴的。在本期的TED演讲中，演讲者将讲述热应激从可补偿到不可补偿的风险与诊断。请结合视频内容，开始口语练习吧！

原文及翻译

When you exercise, nearly 80 percent of the energy you use is transformed into heat. In normal circumstances, this is what's known as compensable heat stress, and your body can dissipate the heat as quickly as it's generated through cooling methods like the evaporation of sweat. But with uncompensable heat stress, your body is unable to lose enough heat due to overexertion or high temperatures in humidity, which raises your core temperature beyond normal levels.

当你运动时，你消耗的能量有近80%转化为热量。在正常情况下，这就是所谓的可补偿热应激，你的身体可以通过蒸发汗水等冷却方法尽快散发热量。但是由于不可补偿的热应激，你的身体由于过度运动或高温潮湿而无法失去足够的热量，这会使你的核心温度超过正常水平。

This causes the proteins in cell membranes to denature, creating cells that no longer function properly and begin to leak their contents. If these leaky cells proliferate through the body, the results can be devastating, including liver damage, blood clot formation in the kidneys, damage to the gastrointestinal tract, and even the failure of vital organs.   

这会导致细胞膜上的蛋白质变性，使细胞不再正常工作，并开始泄漏其内容物。如果这些渗漏的细胞在体内扩散，结果可能是毁灭性的，包括肝损伤、肾脏血栓形成、胃肠道损伤，甚至重要器官衰竭。

So, how do you diagnose an exertional heatstroke? The main criterion is a core body temperature greater than 40 degrees Celsius, observed along with physical symptoms such as increased heart rate, low blood pressure, and rapid breathing, or signs of central nervous system dysfunction, such as confused behavior, aggression, or loss of consciousness.

那么，如何诊断劳累性中暑呢?主要标准是核心体温超过40摄氏度，并伴有心率加快、低血压、呼吸急促等身体症状，或行为混乱、攻击性、意识丧失等中枢神经系统功能障碍的迹象。
