记住这几个数字吧，一千两百毫升，也就是平均计算一个成年人一天所需的水量；二十五度，太冰的水会诱发心脑血管疾病，太烫则会伤害食道，诱发食道癌，所以温水对健康最有利。

You should memorize these figures: 1200 milliliters, which is how much water an adult needs a day on average; 25 degrees; water that's too cold will cause damage to the blood vessels in the brain and the heart, water that's too hot will damage the oesophagus, and cause oesophageal cancer. So warm water is best for your health.
