答案Oxygen氧气 Oxygen, that thing you breathe, / that essential gas that keeps the world going round / is really more important than you give it credit for. / Oxygen is what essentially and literally keeps you alive and keeps you going. / Consider this: people can survive for a few days without food and water, / but do you think a person can survive even a few minutes without oxygen? / No, the brain would die and the heart would stop pumping immediately. / This is how essential oxygen is to the human body. / It is used to convert fats and proteins from the food we consume into heat and energy / for the body and its normal functioning. / Oxygen is essential for the production of living cells / and for respiration of these cells as well. / Oxygen is also used in removing toxic waste from the body. / Quite simply put, the more the oxygen there is in the body, / the more energetic the body will be. /
