留美老師帶你每日說英文 第400期:水的化學性質

ing-bottom: 100%;">

臺灣籍旅美老師今天交給我們的句子是：

Well the water itself doesn't have any sugars or proteins like food so microbes aren't consuming it and rotting it. However, that's not to say the chemistry of the water hasn't changed.
水並不像食物一樣含有糖或蛋白質，所以微生物無法在其中滋生並使其腐壞，然而這並不代表水的化學性質沒有改變。
