TED演講-口語練習：了解運動中的熱應激

在TED演講節(jié)目中，演講者清晰的口語表達及其內容的寫作手法都是值得我們學習借鑒的。在本期的TED演講中，演講者將講述熱應激從可補償到不可補償的風險與診斷。請結合視頻內容，開始口語練習吧！

原文及翻譯

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.

當你運動時，你消耗的能量有近80%轉化為熱量。在正常情況下，這就是所謂的可補償熱應激，你的身體可以通過蒸發(fā)汗水等冷卻方法盡快散發(fā)熱量。但是由于不可補償的熱應激，你的身體由于過度運動或高溫潮濕而無法失去足夠的熱量，這會使你的核心溫度超過正常水平。

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.   

這會導致細胞膜上的蛋白質變性，使細胞不再正常工作，并開始泄漏其內容物。如果這些滲漏的細胞在體內擴散，結果可能是毀滅性的，包括肝損傷、腎臟血栓形成、胃腸道損傷，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，如何診斷勞累性中暑呢?主要標準是核心體溫超過40攝氏度，并伴有心率加快、低血壓、呼吸急促等身體癥狀，或行為混亂、攻擊性、意識喪失等中樞神經系統(tǒng)功能障礙的跡象。
